- 0:00 - Introduction to the Problem: The video introduces the topic of setting up a WireGuard Side-to-Side VPN with a Fritzbox, which the presenter sarcastically calls a "stupid little thing" due to its limitations in this context.
- 0:23 - Demonstration Goal: The aim is to show how to configure a side-to-side VPN between a Fritzbox and an IP464 cloud router, and then analyze packet behavior with Wireshark.
- 0:46 - Initial Fritzbox State: The Fritzbox is shown connected to DSL with no existing VPN configurations.
- 0:59 - Cloud Router & Peer Setup: A new IP464 cloud router gateway is configured, defining two WireGuard peers: "Fritzbox" (Peer 1) and "my PC" (Peer 2). Internal IP addresses (e.g., 10.7.0.0/20) and the Fritzbox's local network (192.168.178.0/24) are defined for routing.
- 2:11 - Routing Table Configuration: A route is added on the cloud router to direct traffic destined for the Fritzbox's local network (192.168.178.0/24) towards the Fritzbox's WireGuard tunnel IP (10.7.0.2).
- 3:08 - Fritzbox WireGuard Import: The generated WireGuard configuration file is downloaded and imported into the Fritzbox. The Fritzbox successfully connects and acknowledges the remote network (10.7.0.0/20).
- 4:23 - PC WireGuard Configuration: The PC's WireGuard client is configured as Peer 2, setting its allowed IPs to include the Fritzbox's local network (192.168.178.0/24) to ensure traffic for that network is tunneled.
- 6:04 - Initial Connectivity Tests (Successes):
- Ping to the PC's own tunnel IP (10.7.0.3) works.
- Ping to the Cloud Router Gateway (10.7.0.1) works (~20ms latency).
- Ping to the Fritzbox's tunnel IP (10.7.0.2) works (~40ms latency), confirming the full tunnel path.
- Accessing the Fritzbox's web interface via its tunnel IP (10.7.0.2) works perfectly.
- 7:37 - The Core Problem Revealed (Failures):
- Pinging the Fritzbox's local LAN IP (192.168.178.1) appears to work, but the reply packet's source IP is observed to be 10.7.0.2 (the Fritzbox's tunnel IP), not the expected 192.168.178.1.
- Attempting to access the Fritzbox's web interface via its local LAN IP (192.168.178.1) fails.
- 9:48 - Wireshark Analysis & Source NAT Explanation: Using Wireshark, the presenter demonstrates that when a TCP SYN packet is sent to 192.168.178.1, the Fritzbox receives it and attempts to reply. However, the Fritzbox performs Source NAT, changing the source IP of the response packet from 192.168.178.1 to 10.7.0.2. The PC's operating system rejects this response because it comes from an unexpected source, thus preventing TCP sessions from establishing, while ICMP (ping) is less strict and still registers a reply.
- 13:17 - Conclusion and Proposed Solutions: The Fritzbox's unconfigurable Source NAT on VPN tunnel traffic makes it unsuitable for "clean" side-to-side VPNs, particularly for accessing TCP-based services on the remote LAN.
- Workaround: Implement Source NAT on the other side of the tunnel (on the PC/cloud router) to match the Fritzbox's behavior (less ideal).
- Recommended Solution: Place a dedicated device (e.g., a Raspberry Pi) behind the Fritzbox to handle the WireGuard VPN connection. This dedicated device will route traffic cleanly without unintended SNAT, with the Fritzbox simply forwarding relevant traffic to the Pi via a static route.
- 15:17 - Final Verdict: The Fritzbox, despite its "jack of all trades" nature, is deemed a "disaster" for specific, advanced networking tasks like proper side-to-side VPNs due to its unconfigurable NAT behavior.
- 0:00:02 The Explosive Allegation: The Wall Street Journal published a story about a letter Donald Trump allegedly sent to Jeffrey Epstein for his 50th birthday in 2003. The letter reportedly featured a drawing of a naked woman and a poem about a "wonderful secret" they shared.
- 0:00:43 Trump's Preemptive Behavior: The video contextualizes the story by highlighting Trump's recent and strange behavior, where he has preemptively dismissed the unreleased Epstein files as "phony stuff" and a "hoax."
- 0:02:02 The Letter's Incriminating Content: The alleged typewritten note within the drawing contains several troubling phrases, including "enigmas never age" and the closing line, "may every day be another wonderful secret."
- 0:03:32 Trump's Strong Denial: In an interview with the Journal, Trump firmly denied writing the letter or drawing the picture, calling it a "fake thing," stating it wasn't his language, and threatening a lawsuit.
- 0:05:01 Corroborating Evidence via Others: While Trump is the only person to issue a firm denial, other individuals mentioned in the WSJ article as having written letters for the same birthday album, such as Alan Dershowitz, gave non-denial responses.
- 0:06:36 Contradicting the Denial: The video presents evidence that Trump has created and donated marker "doodles" for charity auctions in the past, directly contradicting his claim that "I don't draw pictures." This is compared to Prince Andrew's discredited "no sweat" denial.
- 0:08:35 The Bookbinder Connection: A key claim in the WSJ report—that the album was made by bookbinder Herbert Weitz—is corroborated by a 2003 archived version of the bookbinder's website, which lists Jeffrey Epstein as a client.
- 0:12:40 A Call for Real Evidence: In response, Trump has called on his potential AG to release grand jury transcripts. The narrator argues this is a distraction, as the central piece of evidence is the physical letter and album, which would not be in a transcript.
- 0:14:51 A Call for Caution and More Proof: The video concludes by urging viewers not to immediately dismiss or accept the story. While there is significant corroborating circumstantial evidence, the definitive proof—a photo of the letter itself—has not been released by the Wall Street Journal or the DOJ.
- 0:00 Impressive Value: The video introduces the Luckfox Lyra Zero W, a $17 single-board computer (SBC) capable of running a full Ubuntu environment with WiFi and 40 GPIO pins.
- 0:44 Hardware Specifications: The board is detailed, featuring a Rockchip RK3506B SOC (3x ARM Cortex-A7 cores), 512MB RAM, 256MB SPI flash, SD card slot, USB-C, and a MIPI DSI interface in a Pi Zero form factor.
- 3:23 Quick and Easy Setup: Out of the box, the device boots in under 12 seconds into a Buildroot OS and is immediately accessible via ADB over a single USB-C cable.
- 4:53 Low Power Consumption: Power measurement shows the device idles at approximately 130mA (around 0.65W at 5V), making it suitable for low-power applications.
- 6:14 Flashing and OS Options: The video demonstrates how to flash a new Buildroot image to the internal SPI flash and also showcases a custom-built Ubuntu 22.04 LTS image running from an SD card.
- 11:30 WiFi Configuration: A step-by-step guide is provided for configuring and connecting to a WiFi network on both the Buildroot and Ubuntu operating systems.
- 13:19 Performance Benchmarking: Using a custom Python script, the SBC's performance is benchmarked, showing it is significantly more powerful than microcontroller-class devices like the RP2040 and ESP32-P4.
- 17:21 Driving a DSI Display: The board is shown to be capable of driving a 10.1-inch, 1280x800 DSI touchscreen display directly with no extra configuration needed.
- 18:46 Full Desktop Environment: The video demonstrates the installation and use of a full graphical desktop (XFCE via
xubuntu-desktop) on the device, showcasing a usable, albeit software-rendered and laggy, desktop experience. - 9:49 & 20:35 Giveaway and Availability: The presenter announces a giveaway for four of the boards and notes that they are available for purchase from his online store.

*Abstract:*
This video demonstrates the setup and inherent limitations of a WireGuard side-to-side VPN connection using a consumer-grade AVM Fritzbox router and an IP464 cloud router. The presenter successfully establishes the VPN tunnel and confirms basic connectivity via ping and web interface access to the Fritzbox's tunnel IP. However, a critical issue is revealed: when attempting to access devices in the Fritzbox's local network, while ping responses are received, TCP-based services (like browser access) fail. Wireshark analysis conclusively shows that the Fritzbox performs unconfigurable Source Network Address Translation (SNAT) on outgoing VPN traffic originating from its LAN, changing the source IP of response packets from the expected local network address to its own WireGuard tunnel IP. This behavior breaks TCP sessions as the receiving end expects the original source IP. The video concludes by labeling the Fritzbox as "stupid" for this unconfigurable flaw in side-to-side VPN scenarios and suggests a workaround: using a dedicated device like a Raspberry Pi behind the Fritzbox to handle the VPN, circumventing the Fritzbox's unwanted NAT.

The green LED looks different from the others and uses phosphor conversion because of the "green gap" problem where green InGaN emitters suffer efficiency droop at high currents. Phosphide based emitters don't start becoming efficient until around 600nm so also can't be used for high power green emitters. See the paper and plot by Matthias Auf der Maur in his 2015 paper on alloy fluctuations in InGaN as the cause of reduced external quantum efficiency at longer (green) wavelengths.

Narrowband filters we use in Astronomy (Astrophotography) are sided- they work best passing light in one direction so I guess the arrows on the filter frames indicate which way round to install them in the filter wheel.

The smearing on the image could be due to the fact that you don't use a shutter, so you see brighter stripes under bright areas of the image as you still iluminate these pixels while the sensor data ist shifted out towards the top. I experienced this effect back at university with a LN-Cooled CCD for Spectroscopy. The stripes disapeared as soon as you used the shutter instead of disabling it in the open position (but fokussing at 100ms integration time and continuous readout with a focal plane shutter isn't much fun).

The red LED reminds me of one from Roithner Lasertechnik. I have a Symbol 2D scanner which uses two very bright LEDs from that company, one red and one red-orange. The red-orange is behind a lens which focuses it into an extremely narrow beam.

Maybe the camera should not be illuminated during readout.
From the datasheet of the sensor (Onsemi): saturation 40300 electrons, read noise 12.5 electrons per pixel @ 18MHz (quite bad). quantum efficiency 62% (if it has micro lenses), frame rate 1 Hz. lateral overflow drain to prevent blooming protects against 800x (factor increases linearly with exposure time) saturation exposure (32e6 electrons per pixel at 4ms exposure time), microlens has +/- 20 degree acceptance angle
i guess it would be good for astrophotography

so I've stripped all the bits of the
0:01
optical system so basically we've got
0:03
the uh the camera
0:05
itself which is mounted on this uh very
0:09
complex
0:10
adjustment thing which obviously to set
0:13
you the various tilt and uh alignment
0:15
stuff then there's two of these massive
0:18
lenses I've taken one of these apart I
0:20
think there's something like about eight
0:22
or nine Optical elements in here these
0:25
don't seem to do a great deal in terms
0:26
of electr magnification they're obiously
0:28
just about getting the image to where it
0:29
uh where it needs to be just so that
0:33
goes like that then this Optical block I
0:36
originally thought this was made of some
0:37
s crazy heavy material but it's just
0:39
really the sum of all these Optical bits
0:41
are just ridiculously heavy those lenses
0:43
are about 4 kilos each and then there's
0:45
this very heavy very solid um piece that
0:47
goes in the middle and this is so this
0:49
is the filter wheel assembly with a
0:51
hilariously oversized steper
0:53
motor driving this wheel with these very
0:57
large narrow band filters so we've got
1:00
various different shades of uh
1:03
filters there five Al together that
1:06
one's actually just showing up a silver
1:07
that's actually a a red but fairly low
1:10
transmission orangey red blue green
1:15
there's an excess cover on this side so
1:16
the filters can be accessed and changed
1:19
without taking anything else apart even
1:21
this is like ridiculous it's like solid
1:23
aluminium this is just basically a cover
1:25
the actual wavelengths of these are um
1:27
488 525 570 630 and 700 NM not sure what
1:32
the suffix on that perhaps that's the uh
1:34
the width of the spectral line say these
1:37
are very narrow band filters most of
1:39
them are you very little light through
1:41
so it's still very tight narrow band to
1:43
match the um fluoresence of the dies
1:45
they're using in the biochemical process
1:48
and obviously to reject the light that's
1:49
being fired at it from that Illuminator
1:51
box and then there's a there's a second
1:53
one of these lenses then the actual sort
1:55
of samples below that so uh very serious
1:58
amount of very uh chunky heavy Optics
2:01
okay let's take a look at this light
2:02
source made by company Lumen Dynamics
2:04
who are now part of
2:06
excelitas self-contained unit power
2:08
connector USB and this which one of the
2:11
Cable Bundle said was a TTL interface
2:14
USB wasn't used in uh the fluid
2:17
application output here and I think this
2:19
is an input for um light feedback I
2:21
don't if it's regulated or just a measur
2:23
measurement facility and the uh fiber
2:27
assembly
2:29
Square Inlet there and then there's two
2:32
outputs which have uh lens assemblies
2:35
and this small one which goes back into
2:37
that small Port just Loops out of here
2:40
straight back in So on this side we've
2:42
got the electronics which look pretty
2:44
straightforward we've got a bit of power
2:45
supply stuff over here and we've got
2:48
separate drivers for each wavelength now
2:50
interesting this is clearly been very
2:52
specifically made for this application
2:54
you I was half expecting like say some
2:56
generic drivers that could be used for a
2:58
number of different things but actually
3:00
literally specified the exact wavelength
3:02
on the PCB there is provision here for
3:04
385 NM which isn't populated but this is
3:07
clearly been designed very specifically
3:09
so these four drivers look the same but
3:10
then there's two higher power ones for
3:12
575 and
3:14
520 a slightly bigger heat sink on this
3:16
575 section there a p 24 which is
3:20
providing USB interface USB isolator the
3:23
USB interface just presents as a comport
3:26
I did have a quick look but I didn't
3:27
actually get anything sensible um I did
3:29
dump the Pi code out and there's a few
3:31
you a few sort of commands that you
3:32
could see in text but I didn't actually
3:34
manage to get it working properly I
3:36
found some software for related version
3:38
but it didn't seem to want to talk to it
3:39
but um I say that wasn't used for the
3:41
original application it might be quite
3:42
interesting to get try and get the Run
3:44
hours count out of it and the TTL
3:46
interface looks fairly straightforward
3:48
we've got positions for six opto
3:50
isolators but only five five are
3:52
installed so that corresponds with the
3:54
unused thing so I think this hopefully
3:56
should be as simple as just providing a
3:57
ttrl signal for each color to uh enable
4:00
it a big heat sink here which is there I
4:03
think there's like a big S of metal
4:04
plate through the middle of this that
4:05
all the leads are mounted on the other
4:07
side so this is heat sinking it with a
4:09
air flow from a uh just a fan in here
4:13
obviously don't have the air flow
4:14
anywhere near the Optics so conduction
4:17
cool through to this plate that's then
4:18
uh air cooled got some pots which are
4:21
presumably power
4:22
adjustments okay let's take a look at
4:24
the other side which is uh much more
4:27
interesting see we've got some uh very
4:31
uh neatly Twisted cable assemblies there
4:35
a bunch of leads so we've got one here
4:37
475 up here 430 NM 630 575 and 520
4:44
filters and dcro mirrors a quick way to
4:48
see what's white is if we just shine
4:49
some white light through
4:51
here not sure how it is is to see on the
4:54
camera but shining white light we do
4:55
actually get a bit of red a bit of blue
4:57
some yellow here so the obstacle path
5:00
575 it goes sort of here bounces off
5:03
this mirror and goes out the 520 goes
5:07
sort of down here across here and up
5:09
there 630 goes basically straight
5:13
through
5:15
430 goes across there down there along
5:17
there and the 475 goes down here and
5:20
left this is the light sensing thing
5:22
think here there's just a um I think
5:24
there a photo diode or other sensor
5:26
haven't actually taken that off and
5:28
everything's fixed down to this chunk of
5:31
aluminium which acts as the heat
5:32
spreader that then conducts the heat to
5:33
the back side for the heat
5:35
sink and the actual lead packages all
5:38
look fairly similar except for this one
5:41
on the 575 which looks quite a bit more
5:44
substantial big spay
5:46
Terminals and the interface for this
5:48
turned out to be extremely simple it's
5:50
literally a 5V TTL level to enable each
5:54
color doesn't seem to be any tensity
5:56
control but there are some additional
5:58
pins on that connector that weren't used
5:59
in the through time thing so maybe
6:01
there's some extra lines that control
6:02
that I couldn't find any data on this uh
6:05
unit and the um their current product
6:07
range is quite significantly different
6:09
so we've got the uh blue these
6:13
might may well be saturating the camera
6:16
so they might look a bit weird so that's
6:17
the 430
6:18
blue the 575
6:24
yellow uh
6:26
475 light blue
6:29
the uh 520
6:31
green and the uh 630 red now one
6:36
interesting thing I noticed for the
6:39
575 it's actually it's actually using a
6:42
white lead and then filtering it rather
6:44
than using all the other ones are using
6:46
leads which are the fundamental colors
6:47
but uh this is actually doing white and
6:50
it's a combination of this filter and
6:52
the dichroic mirrors that are turning to
6:55
Yellow if we take the filter out and a
6:57
lot of the a lot of the um blue content
7:00
is going this way the red is going
7:02
straight through these two mirrors so
7:05
this is clearly not reflecting much of
7:08
that so we end up with the yellow coming
7:10
out of uh out of there which is a fairly
7:14
light yellow color which you don't
7:16
really see from high intensity leads so
7:19
that's clearly why they've used the
7:20
white to uh do this power consumption of
7:23
the white is pretty high so going up to
7:25
about 2 and 1 half amps on that color
7:27
whereas most of the other colors are
7:28
only drawing half an amp or so at 24
7:30
volts the uh the green is up to about
7:32
1.2 but say this thing is uh much
7:35
brighter and if you actually run all the
7:38
colors at the same time you get a fairly
7:41
reasonable um looking white coming out
7:43
of it and one thing you might just be
7:45
out to notice is there is some sort
7:46
color banding around here that's not
7:49
getting uh everything s completely
7:51
concentric and I think that's where this
7:53
fiber optic thing comes
7:58
in I'll
8:00
get a couple of Fairly accurately shaped
8:04
very sort of uniform color and looking
8:06
at What's um inside here we've basically
8:09
just got this Square Rod so this is
8:12
clearly yeah the lights just bouncing
8:13
off all the all the various sides to um
8:16
get a nice uniform illumination uh this
8:19
back bit looks like it's all potted so
8:21
nothing I really do to get in there I
8:24
think this is fiber so I have come
8:26
across um cables like this which are
8:27
liquid fill but just looking through the
8:30
end of this it's probably a bit hard to
8:31
see it does look like there fiber ends
8:34
going going on there and so there's this
8:36
feedback thing which is just obviously
8:39
compensating for the any light losses
8:41
through here to get an accurate
8:43
representation of uh the light that's
8:45
been launched out of these two
8:47
fibers and you see uh
8:49
these have got this sort of trapezium
8:54
shape light guides again it's like a
8:56
sort of acrylic or glass light guide
9:00
guess projected just to make the right
9:03
rectangular
9:04
shape and look at this Center assembly
9:07
um the light output doesn't uh change
9:10
whether you feed this in or not so it's
9:11
clear not doing any internal Clos Loop
9:14
control obviously there may well be some
9:16
facility for it to do that but it's not
9:17
being used in this
9:19
application and so this output just
9:21
produces a voltage on the uh outle
9:24
connector proportional to the amount of
9:26
light that's present so there's a little
9:28
diffuser in the back there
9:30
and then there's just some kind of uh
9:33
Optical sensor looks like a
9:35
chip looking at the lead it's a very
9:37
small package on the PCB with this lens
9:40
assembly over the top and these look
9:43
like they're actually on a copper
9:44
Metalized PCB for maximum thermal
9:47
performance and yeah it's a very small
9:49
package looks like it's a ceramic
9:51
package and there's a thermister there
9:53
for temperature monitoring this is the
9:56
475 blue one this is the 520 need to
9:59
Green which is uh rather different OB
10:02
it's a much bigger D with lots of bond
10:04
wise but also this looks like it's using
10:05
a phosphor if I shine a blue light at it
10:08
lights up green so this is actually a
10:10
phosphor conversion green lead which
10:12
I've I've come across before they want
10:15
that specific wavelength so they may be
10:17
easier to tune a phosphor than tune the
10:20
um semiconductor material to get the uh
10:23
right right wavelength from the lead
10:24
directly uh red 630 similar size to the
10:28
blue one or does seem to have a uh a
10:31
lens on top of it there is a sort of red
10:33
coloring to
10:35
the die but that doesn't appear to be
10:38
fluorescent as far as I can
10:39
tell and the white one again a little
10:41
bit different sort of much higher
10:43
current
10:46
connectors a makeer name on that
10:48
connector flot light not sure if that's
10:52
the connector or the lead
10:54
itself and obviously with the phosphor
10:56
and I'd imagine that phosphor may well
10:58
be tuned to get the maximum to the uh 5
11:01
cenm and actually this white one looks
11:04
like a St fairly standard product I just
11:06
found it in Mouse made by luminous
11:09
devices in fact actually I think all
11:11
these are based on various luminous
11:13
devices modules and they're you take
11:17
looks like they taking the nearest
11:18
wavelength and then just using these
11:19
filters to clean it up to get a precise
11:22
uh spectral line out of it so quite a
11:25
nice neat and um extreme
11:30
bright light source uh sure I've got any
11:33
particular use for it so I think this
11:35
might end up on
11:36
eBay but uh very pretty to look out and
11:40
without the uh risk of burning your eyes
11:43
out like you do with lasers so I thought
11:45
it would be interesting to try and
11:46
figure out the runtime of this things
11:48
like this we usually keep some sort
11:49
record of runtime cuz leads degrade over
11:51
time I couldn't get any software to work
11:52
through the USB face but then had a
11:54
thought probably going to be writing the
11:55
runtime periodically to the e s prom so
11:58
I just just scope up that and noticed it
12:00
was doing right every 5 minutes so I
12:02
just ran it for a while periodically
12:04
reading the E squ I just held the pick
12:05
in in reset and um put clip over to read
12:07
the square prom and found it was writing
12:10
one location per color every 5 minutes
12:12
so if one color was on it would write
12:14
that location every 5 minutes and just
12:16
increment it by one so after doing a few
12:18
tests with different colors of different
12:19
time periods it looked extremely
12:21
straightforward it's like a four bite
12:22
count for each color looking at the
12:24
original data that was in it all the
12:26
colors apart from Green were reading
12:28
zero and the green was reading four
12:30
indicating a total 20 minutes run time
12:32
ever if it was turned on run for a short
12:34
time then turned off that might not have
12:36
been counted but even so indicates this
12:37
thing wasn't used a great deal the whole
12:40
s process of doing a run can be several
12:42
hours but it'll only be doing probably
12:43
the Imaging at the end of that so you
12:46
wouldn't expect to be running for a long
12:47
time but say a single color for 20
12:50
minutes over its whole lifetime does
12:52
seem a little bit on the low side okay
12:55
let's look at the camera un fortunately
12:57
I managed to not record any sound when I
12:58
did this it's also a couple of months
13:00
ago so there's going to be a few details
13:02
that I've forgotten so I'm just going to
13:04
dub this over the original footage so um
13:07
take the lid off see this massive great
13:10
heat sink so this is a pel cool camera
13:12
we've got this blower fan producing a
13:14
fair amount of air flow through
13:16
it the connector here there's the ccds
13:19
mounted on the board on the
13:24
right this unplugs so we've got a bit of
13:27
power supply stuff on here
13:29
USB interface I think that's the Cyprus
13:32
microcontroller High speeded USB
13:34
interface there's a zyink spon fpga some
13:40
RAM and there's a couple of ATD
13:42
converters can't quite read what those
13:45
those are but anal
13:47
devices um little bit of bodgery around
13:51
here extra decoupling obviously they
13:53
have having some noise issues this is
13:55
around the ram chip quite a lot of extra
13:57
capacitors been added there
13:59
uh there's a couple of amplifiers prior
14:01
to the HD converter buffers or Andor
14:05
amplifiers taking the CCD
14:08
signal um bit more power spy stuff here
14:11
this is probably all to do with
14:12
generating the various CCD bias voltages
14:14
they uh need quite a lot of exotic
14:18
voltages next board down is just a
14:20
shield and an interconnect
14:24
boardly shielding the power supply stuff
14:26
from some the more sensitive an log
14:28
stuff
14:31
and this is the bottom board which is
14:32
just all power supply
14:34
stuff as you can see tons of capacitors
14:37
or Transformer in
14:42
there and this is the CCD which is a uh
14:47
very impressive thing this is a kf50 100
14:50
originally by true sense then codec
14:53
there ON
14:54
Semiconductor it's 50 megapixels uh the
14:58
only price I could find was this one
15:00
5,000 bucks and the architecture you can
15:03
see there actually two separate halves
15:04
which explains the Dual AZ converters
15:06
and two amplifiers it's literally split
15:08
down the middle and duplicated so it's
15:10
outputting two streams in parallel just
15:13
to keep the bandwidth sensible and it's
15:15
got this amazing um diffraction effects
15:18
it's got micro lenses over the pixel so
15:20
there's there's a bit more Optics going
15:22
on than on a normal
15:25
sensor few more bodges on the CCD board
15:28
including this wire which isn't really
15:29
tacked down very well which is a bit uh
15:32
bit of a mess quite a few bits around
15:34
this board where they've uh tacked
15:36
various bits on which is not super
15:38
impressive looks like CCD drivers on the
15:40
left with those 3 ohm um damping
15:43
resistors on the
15:47
output get a few more little bodges
15:50
around here some of
15:52
the and there's this separator the
15:54
silica gel to keep the moisture down but
15:56
there's this separator that actually
15:58
appears to be cut from piece of
15:59
antistatic
16:04
bag and this sort of thermal block on
16:06
top of this stack of three pel Cola
16:12
modules so as with any Stacks they get
16:16
um larger as they go back towards the
16:18
heat sink because each P's got to not
16:20
only take the heat from the previous but
16:21
also the waste heat which is quite
16:27
significant you see a little temperature
16:29
sensor here that copper block which
16:32
makes contact with the back of the
16:37
CCD and this's the back of the
16:40
pelas this then contacts the heat sink
16:44
on the uh rear there a few thermal pads
16:46
as well for some of the other power
16:47
components on this
16:51
PCB okay I've connected this uh camera
16:54
up I found some drivers on the disc that
16:56
seem to work under Windows 7 couldn't
16:58
get to install under Windows 11 though
17:01
um in the absence of any sort of lens or
17:03
being bothered to the proper amount I've
17:04
just put some f over it and put a little
17:06
pin in there to make a pinhole lens and
17:08
software gives a few options I'm not
17:11
entirely sure what all these are there's
17:12
obviously a clock frequency 22 MHz low
17:15
gain and with PFG no idea what that is
17:19
something something game programmable
17:20
Something game perhaps ver exposure
17:23
types I think focus is just like a
17:25
continuous grab until you tell it to
17:27
stop not entirely sure all these options
17:30
are obviously exposure time uh triggers
17:33
there ex external hardware trigger inut
17:35
you just trigger using a um thing on
17:37
screen so the resolution is 8176 by
17:40
6132 and you can actually bin those
17:42
where you combine multiple pixels to get
17:46
increased gain at the expense of lower
17:48
resolution down this is a 10sec exposure
17:51
obviously of the pin hole it's very uh
17:53
intensitive so we just stand still now
17:56
downloading it there's the uh exposure
17:59
so when it's
18:01
um there's a little status thing down
18:03
here so that tells you the um exposure
18:07
[Applause]
18:09
time it's this is just it
18:15
downloading um it is quite I'm seeing
18:18
quite a lot like smearing I think that I
18:20
don't know whether that's just due to
18:21
pixels overloading or something else I
18:24
mean yeah it's not it's not um out of
18:26
the question that there's something not
18:27
totally right about this camera
18:28
certainly was bodge wise on there um I
18:31
don't I'd imagine a camera like this
18:32
it's got a fairly narrow range of
18:34
intensities that it's happy with I'm not
18:36
going to spend a great deal of time on
18:38
this if you're interested in this camera
18:40
maybe for astronomy or something and
18:42
happy to sort of take the risk of it may
18:44
not be uh perfect I'll um I think I'll
18:47
stick this on eBay along with the
18:48
Illuminator I'll put a link down in the
18:50
description to the listing take your
18:52
chances to grab a bargain so for example
18:54
here we see this vertical streaking so
18:56
I'm not sure how normal that is this is
18:58
on fairly bright scene looking out the
19:02
window if I cut the exposure time down
19:04
on that it's now 1 second
19:07
exposure again most of the image
19:09
disappears again this is looks like it's
19:11
possibly over still overloading here go
19:14
that go down to say say quarter a
19:16
second so again I think there might be
19:19
some Auto gain control going on here um
19:21
this is with the PFG option let's try
19:23
turning that off and see what
19:25
happens so I'm not sure this is actually
19:27
more streaking or which just it's
19:29
cranked up the gain all the dis display
19:31
gray scale to show what um you know the
19:33
range of things that it's captured
19:36
there's one of one of 12 things in the
19:38
software there's um you can see of you
19:40
can't seem to read out the temperature
19:42
of the pelta cooler but you can set the
19:44
temperature and if you said it's a
19:46
different temperature you see the power
19:48
consumption jump up running the cooler
19:50
to get the temperature you requested but
19:52
I can't see anything anywhere that tells
19:54
you whether the cool is at the at the
19:56
temperature other than the power
19:57
consumption going down and there's no
19:59
temperature read out
20:03
here and just some yeah this is just
20:05
sort of very basic software I'm sure
20:07
there's like an API for more
20:09
sophisticated
20:10
applications but so if you know anything
20:12
more about these cameras please um stick
20:14
in the
20:15
comments um incidentally when I was
20:18
editing I didn't notice there was a bent
20:19
pin on the um CCD but I did fix that
20:22
before doing these tests and also
20:24
reactivated the um silica gel desicant
20:26
cuz I noticed it was uh I was getting
20:28
bit of condensation on the window but um
20:31
yeah so a couple of uh interesting but
20:34
maybe not particularly uh useful pieces
20:37
of Kit except for someone that's got a
20:38
very specific use so um I'll stick a
20:42
I'll stick these on eBay put a link in
20:44
the description and say hopefully
20:45
someone could actually make some uh good
20:47
use of these things
Example Output:
**Abstract:**
This video presents Part 2 of a teardown focusing on the optical components of a Fluidigm Polaris biotechnology instrument, specifically the multi-wavelength illuminator and the high-resolution CCD camera.
The Lumen Dynamics illuminator unit is examined in detail, revealing its construction using multiple high-power LEDs (430nm, 475nm, 520nm, 575nm, 630nm) combined via dichroic mirrors and filters. A square fiber optic rod is used to homogenize the light. A notable finding is the use of a phosphor-converted white LED filtered to achieve the 575nm output. The unit features simple TTL activation for each color, conduction cooling, and internal homogenization optics. Analysis of its EEPROM suggests extremely low operational runtime.
The camera module teardown showcases a 50 Megapixel ON Semiconductor KAF-50100 CCD sensor with micro-lenses, cooled by a multi-stage Peltier stack. The control electronics include an FPGA and a USB interface. Significant post-manufacturing modifications ("bodges") are observed on the camera's circuit boards. Basic functional testing using vendor software and a pinhole lens confirms image capture but reveals prominent vertical streaking artifacts, the cause of which remains uncertain (potential overload, readout artifact, or fault).
**Exploring the Fluidigm Polaris: A Detailed Look at its High-End Optics and Camera System**
* **0:00 High-End Optics:** The system utilizes heavy, high-quality lenses and mirrors for precise imaging, weighing around 4 kilos each.
* **0:49 Narrow Band Filters:** A filter wheel with five narrow band filters (488, 525, 570, 630, and 700 nm) ensures accurate fluorescence detection and rejection of excitation light.
* **2:01 Customizable Illumination:** The Lumen Dynamics light source offers five individually controllable LED wavelengths (430, 475, 520, 575, 630 nm) with varying power outputs. The 575nm yellow LED is uniquely achieved using a white LED with filtering.
* **3:45 TTL Control:** The light source is controlled via a simple TTL interface, enabling easy on/off switching for each LED color.
* **12:55 Sophisticated Camera:** The system includes a 50-megapixel Kodak KAI-50100 CCD camera with a Peltier cooling system for reduced noise.
* **14:54 High-Speed Data Transfer:** The camera features dual analog-to-digital converters to manage the high data throughput of the 50-megapixel sensor, which is effectively two 25-megapixel sensors operating in parallel.
* **18:11 Possible Issues:** The video creator noted some potential issues with the camera, including image smearing.
* **18:11 Limited Dynamic Range:** The camera's sensor has a limited dynamic range, making it potentially challenging to capture scenes with a wide range of brightness levels.

* **20:38 Availability on eBay:** Both the illuminator and camera are expected to be listed for sale on eBay.
Here is the real transcript. Please summarize it:
00:00:01 Hello everyone, today I want to
00:00:01 show you what a stupid little thing
00:00:05 a Fritzbox can be when it comes to this
00:00:07 topic. Side to Side VPN connection
00:00:10 using Zeg Guardard. And yes, you
00:00:12 heard right, a box like this is
00:00:14 often an all-rounder and can be found in
00:00:16 many households, but
00:00:18 nevertheless, it remains that way. Such a thing
00:00:20 is, after all, a small, stupid thing. But
00:00:23 why am I telling you this? I'll
00:00:25 now show you step by step how
00:00:27 I'm going to set up a side-to-side VPN
00:00:29 connection, like the one this box
00:00:30 offers us, on the Fritzbox
00:00:33 with the new cloud router from
00:00:35 IP464 and we'll take a look at the Wire Shark
00:00:39 and the packets and
00:00:41 see how small this
00:00:44 Fritzbox actually is. Let's
00:00:46 get started. So, we have
00:00:48 the Fritzbox here as usual. You see, it is
00:00:50 currently connected to DSL as normal
00:00:52 . No problem at all. And
00:00:54 we don't have anything here under Internet Sharing,
00:00:56 VPN Wegard.
00:00:59 Wonderful. We go to the cloud router.
00:01:01 We are adding a new cloud router.
00:01:03 We want to access this Fritzbox from outside, from
00:01:05 somewhere on the Internet,
00:01:07 or with VPN through this
00:01:11 Fritzbox to the end devices in the
00:01:13 background. So a side-
00:01:15 to-side VPN connection. But since we
00:01:18 have this V6 problem and
00:01:19 what not, we use
00:01:21 a gateway like this. But all right,
00:01:23 let's get everything set up. We now have a
00:01:24 new gateway here, and we're setting up
00:01:26 a second pier right away, because I
00:01:28 want to
00:01:29 connect to my PC somehow. But
00:01:31 let's start with Pier 1.
00:01:33 So, we go in here, let's
00:01:35 just say Pier 1 is ultimately the
00:01:37 Fritzbox and press save so that it
00:01:39 connects, let's say
00:01:41 a Keep Live, then it does it
00:01:42 automatically with a Keep and
00:01:45 down here with the Allocate addresses, I'll
00:01:47 do it a bit quicker, we'll get
00:01:49 to a DeepDive video at some point
00:01:50 , I'll enter that now, all right
00:01:53 10.7.0.0/20
00:01:55 0/20
00:01:56 this Fritzbox can now simply
00:02:04 communicate outwards via the Load IP addresses so that you
00:02:04 can also send me response packets via the
00:02:06 corresponding tunnel. This completes the
00:02:09 configuration for the Fritzbox
00:02:11 . We
00:02:12 still have to set up a route now, but
00:02:14 okay. Configuration is now
00:02:16 complete. Now we'll quickly create
00:02:17 the route for the Fritzbox. That means
00:02:19 we're saying new routing table here,
00:02:22 or new entry 122 168 178.
00:02:26 That's the network behind this Fritzbox
00:02:28 here.0/24
00:02:31 to 10,702.
00:02:34 This is the IP address of the
00:02:35 Fritzbox. 10702
00:02:38 is also there and we say route.
00:02:41 Now my gateway knows. Understood.
00:02:43 Requests come in towards
00:02:45 network 178 side to side.
00:02:49 Please just send this to the Fritzbox, to the
00:02:51 box here. She knows the net and she holds
00:02:53 this net tight. Everything's fine, get in touch
00:02:55 . We can check this by
00:02:57 clicking here on Getli Rooting Table
00:03:00 and there it says 178.0/24.
00:03:04 Please send 10702 to this
00:03:06 Fritzbox. So everything is wonderful. We
00:03:09 go back, we go to the pier and we
00:03:11 now get the configuration from
00:03:13 this Fritzbox. That means we
00:03:14 just say show config, everything is
00:03:17 in there. We get an IP, a bit of
00:03:18 DNS, a bit of private key, and here
00:03:21 under Load IPs we simply see
00:03:23 10700. This means that this Fritzbox
00:03:26 is allowed to send packets in the direction of 10700/20
00:03:31 .
00:03:33 So I have everything I need. I
00:03:35 now say download file here, go to my
00:03:37 Fritzbox, add connection, then
00:03:40 I clearly say I want side to side
00:03:42 . All right, we have them all.
00:03:44 Then he asks me the question, has
00:03:46 anyone else already
00:03:48 created this configuration? Yes, of course,
00:03:49 of course I do. So yes, we
00:03:52 simply enter a name for this
00:03:53 connection and select our
00:03:55 neatly created
00:03:58 configuration file and simply say
00:04:00 come on, finish. Just pump it all
00:04:02 in there. She doesn't complain either
00:04:04 . She says everything is fine. I
00:04:06 recognized everything, all IP addresses were
00:04:08 nice and clean. It now also says
00:04:10 remote network 10,700/20.
00:04:17 This means that it also knows where to
00:04:17 send packages if
00:04:19 any packages need to be sent in that direction
00:04:22 . Now
00:04:24 we have to finish my PC.
00:04:26 We said that we have a
00:04:27 second pier. This is the second pier
00:04:28 here. Edit Pier. Let’s call it
00:04:30 my PC. He has the 03 at the end.
00:04:34 We don't have to do that. We don't have to
00:04:35 do anything. We don't have to do anything.
00:04:36 We don't have to do anything. We don't have to
00:04:37 do anything. We press save. The
00:04:39 only thing we can do is
00:04:40 , I don't want my
00:04:42 PC to send all sorts of things everywhere,
00:04:44 I can
00:04:46 just tell my configuration here to use this
00:04:48 tunnel to send 10700 so that
00:04:51 my PC can reach everything, and
00:04:54 of course my configuration wants to
00:04:56 get into the Fritzbox network. No problem, let
00:04:59 's make 1 and 2168 1780/24.
00:05:07 So, now my configuration knows
00:05:07 about my device. It could
00:05:09 be my cell phone here too. Whatever what I know
00:05:11 now all right, if you want to go to 178.0/24
00:05:17 , off into the tunnel with it.
00:05:19 Configuration complete. We're not doing
00:05:21 anything different here. Oh, you see
00:05:22 , the Fritzbox is already green. The
00:05:23 Fritzbox has already connected. We
00:05:25 see it here. Now we need to
00:05:27 take our configuration. I just say
00:05:29 Copy to Clipboard. It has everything
00:05:31 I need. Open my Wirard.
00:05:33 Just edit this. Insert that
00:05:35 there. Everything in there. Wonderful. We
00:05:38 press save. We press
00:05:39 activate. We are connected. The
00:05:41 only thing I have to do now is
00:05:45 unplug the black cable from the Fritzbox, because that was my
00:05:45 direct connection from my PC
00:05:47 . To be on the safe side,
00:05:48 we briefly press deactivate,
00:05:50 activate again. So, because now my PC is
00:05:53 no longer connected to this Fritzbox
00:05:55 . It only has internet
00:05:57 and now, theoretically, we should be able to
00:06:04 access this Fritzbox via the internet. And yes, how do
00:06:04 you always test that? You always test
00:06:05 yourself from the smallest to the largest.
00:06:08 Then I would suggest that we
00:06:10 simply do the whole thing by
00:06:11 opening a nice CMD window
00:06:13 and then pinging our way
00:06:15 through it. So, my PC has
00:06:17 0.3.
00:06:19 Oh, look, it even says
00:06:21 ping 10.70.3.
00:06:24 I can ping myself. Okay,
00:06:26 minus less than a millisecond. Everything's
00:06:28 cool. Then let's just make
00:06:30 the gateway, so that we can reach the 7.0.1,
00:06:34 which
00:06:36 is the gateway of the IPv64 Cloud Router
00:06:38 . We can see that it's already over 20
00:06:40 milliseconds. We can still see here on the
00:06:42 left that a few
00:06:44 kilobytes are zipping around, right?
00:06:45 You can see everything beautifully. So
00:06:47 let's just take those two
00:06:50 . The second is the Fritzbox. Here, too,
00:06:52 you can tell quite clearly from the
00:06:54 milliseconds. My
00:06:56 connection goes out to the Cloud Gateway
00:06:58 at IP464 and goes back from the Cloud Gateway
00:07:01 to the DSL line
00:07:03 . Totals to about 40
00:07:06 milliseconds. Sure, forward weight 20
00:07:08 milliseconds, reverse weight 20
00:07:09 milliseconds, completely normal. Two
00:07:11 different internet connections, everything's
00:07:13 cool. That means we can
00:07:15 actually get this 10.7.0.2
00:07:18 . What's the
00:07:20 best way to look at this and prove it even more
00:07:22 ? Sure, we just enter
00:07:24 7.0.2 here in the browser.
00:07:27 Look at that. What a coincidence. We
00:07:29 can access this Fritzbox quite
00:07:32 normally. Works perfectly. Well,
00:07:35 now the problems
00:07:37 finally begin, because we have
00:07:38 n't even tested the remote
00:07:41 network once yet, and
00:07:43 we're going to take a look at that now. And first of all,
00:07:45 I'm going to cause a lot of confusion. We
00:07:47 know that my PC can be connected side to side
00:07:50 using this
00:07:51 configuration, using the routing that
00:07:54 we have set up here. We'll take
00:07:56 another look at it. Routing table, there it
00:07:58 is. Anything that goes towards 178.0
00:08:02 , please send it to the Fritzbox.
00:08:04 What is written there is also correct.
00:08:06 We'll take a look. Now comes the
00:08:07 confusion. Ping 192 168178.1
00:08:15 is the Fritzbox here. We said,
00:08:15 all right, we can ping there via this
00:08:16 tunnel. Ping off.
00:08:19 Wonderful, we get an answer.
00:08:21 Aha, okay. Now the very first thing we think is
00:08:23 ,
00:08:25 that actually looks wonderful.
00:08:26 That's what I ultimately
00:08:28 want. But now there is a small
00:08:30 difference. Do you see the difference
00:08:31 between the point 1 is
00:08:34 here. Do you see the difference? 40
00:08:36 milliseconds actually looks cool,
00:08:37 right? Now let's do the whole thing again
00:08:40 to 10.7.0.2,
00:08:42 which is also the Fritzbox. Hm. 40
00:08:44 milliseconds is also possible, but
00:08:47 here you have to pay attention not to the
00:08:49 command that I send, but to the
00:08:51 response, so to speak,
00:08:54 and then things get complicated. I'll
00:08:56 do it again. 178.1.
00:08:59 What do you notice about the answer? I
00:09:02 receive a reply from
00:09:06 10.70.
00:09:09 and not from the goal I
00:09:11 mentioned. And now I'll show you in
00:09:13 more detail why this is a problem
00:09:15 and what the
00:09:18 stupid little Fritzbox is doing wrong.
00:09:20 Look, we were just able to
00:09:22 type this in the browser perfectly. We get
00:09:24 to 10.7.0.2, we can work, we
00:09:26 get to the Fritzbox, that's no
00:09:28 problem. In theory you should
00:09:30 then be able to say 192 168 178.1,
00:09:35 which is the Fritzbox.
00:09:38 Yes, it doesn't work. It's weird. I can ping
00:09:41 , but things
00:09:44 like opening a browser do
00:09:46 n't work anymore. It's kind of weird.
00:09:48 I'll now show you why this
00:09:50 is the case. That means if we
00:09:52 go here now and just do
00:09:53 a Wirk and
00:09:55 say mercilessly, please listen to
00:10:04 what is happening here on my Wiru interface, on my PC. Let's
00:10:04 go to the browser and refresh
00:10:06 the browser. Take a look at the Wire
00:10:08 Shark and we can end the Wire Shark now
00:10:11 . I know it was
00:10:12 all very, very small. I'd have to
00:10:13 roll a little closer, but you can still
00:10:15 see something perfectly. Let's go
00:10:18 to line 7 here. My PC
00:10:22 just did the following:
00:10:24 opened the browser and said: "Hey,
00:10:26 Fritzbox, hello." With the IP address
00:10:29 178.1, h and sends you
00:10:33 a synd packet on port 7.
00:10:37 The Fritzbox also says, oh, there's a
00:10:41 data packet. Super 1A. And then
00:10:44 the Fritzbox says: "Yes, I'm
00:10:46 replying to the packet." You can
00:10:48 clearly see here that a
00:10:50 synac package is coming.
00:10:52 The big problem is that the Fritzbox does
00:10:54 not respond with its IP address
00:10:57 178.1,1, but rather it responds, just
00:11:00 as we have just seen here,
00:11:02 with its tunnel IP address, instead of with
00:11:05 its side to side IP address. Well, and since
00:11:09 ICMP is ultimately different from
00:11:13 TCP, say my PC is here or my browser
00:11:16 or my network interface,
00:11:18 guess something, I don't
00:11:19 care. Wait a minute, wait a minute. I have
00:11:25 received a response package from someone.
00:11:25 I didn't even mention that one. Wait
00:11:27 with that one. Wait a minute. Stop, stop. I do
00:11:29 n't want to talk to him. I'm
00:11:31 not interested in the 10702. I
00:11:33 mentioned the 1178.1. Why am I getting
00:11:37 your answer from you, bum? Well, and
00:11:39 that's ultimately the big
00:11:41 problem, that the Fritzbox goes and
00:11:44 then uses this nice alleged, let's
00:11:47 say, yes, maybe sometimes
00:11:49 it's a bit like that, it just makes
00:11:50 a so-called sourceut. A
00:11:54 source nut is exactly that. All
00:11:56 packages that come in here now
00:11:57 also zip to their destination.
00:11:59 We can also hang a PC behind here
00:12:00 . This even affects the PC.
00:12:04 The PC even responds to that. No
00:12:08 problem. The problem, however, is
00:12:11 that the Fritzbox now goes there, and with
00:12:13 the response packet that comes back to the box
00:12:14 , which is supposed to go out through the VPN tunnel
00:12:16 , the Fritzbox says: "Yes,
00:12:19 yes, I know, no problem. I'll send
00:12:21 the data packet out too." We can see it
00:12:23 here in the Wehark, but it's just doing
00:12:26 a source nut. This means that it changes the
00:12:30 data packet in the source area, i.e.,
00:12:33 where the IP address comes from, no
00:12:36 longer from 178. With the
00:12:38 source, it changes the IP address from its
00:12:40 IP address in the tunnel network. That's
00:12:43 what we ultimately
00:12:45 see here: 10,702.
00:12:48 The response packet no longer comes from
00:12:50 where we want it to come from. This
00:12:53 means that in this construct, as we
00:12:56 actually want it, we
00:12:57 want to access something behind
00:13:00 this Fritzbox from the outside, say,
00:13:03 simple TCP sessions,
00:13:06 no, I don't want that, because the
00:13:09 response packet doesn't come from where I
00:13:11 sent it. Well, and I ca
00:13:14 n't explain it any better, because
00:13:15 that's what the problem here is.
00:13:17 caused, right? It doesn't
00:13:19 matter whether I only query point 1
00:13:20 or the PCs behind it
00:13:23 . The problem can no
00:13:25 longer be solved this way, because this box here
00:13:28 simply creates a source nut. There are two
00:13:31 possible solutions from my point of view, and
00:13:33 I don't want to show you them now, because
00:13:34 I want to present a solution
00:13:36 as a separate video after this video
00:13:38 , because it doesn't make sense to do it
00:13:39 here. So
00:13:41 we'll do the whole thing theoretically now.
00:13:43 The problem should be clear to you now.
00:13:44 This little box is a small beep
00:13:48 and simply changes IP addresses on its
00:13:51 tunnel network. Yes, you could think that's
00:13:53 good, but in our case, if
00:13:55 we want to set up a side-to-side,
00:13:56 bad. Theoretically, what can you
00:13:58 do? Well, on the other side of the
00:14:01 tunnel you could go and
00:14:03 work with a source nut, so
00:14:06 that the IP addresses are
00:14:08 somewhat disguised. Who
00:14:10 comes from where with which IP address would work
00:14:12 . But the much better
00:14:14 solution is if you somehow
00:14:16 really have a, let's call it If you
00:14:18 want to do a clean side-to-side connection,
00:14:21 you can continue using the box,
00:14:22 but my top tip is to connect
00:14:25 a Raspberry Pi behind the Fritzbox
00:14:28 , which simply takes over the VPN connection
00:14:30 , because it does
00:14:32 n't do anything like that. It
00:14:34 also routes the data packets that
00:14:36 come in
00:14:39 through the tunnel without any source-nothing.
00:14:42 This means that you simply set up a
00:14:44 route here. Send everything that goes towards 10.7
00:14:46 point something
00:14:48 to the Raspberry Pi, and the Raspberry Pi
00:14:50 then takes over cleanly and well
00:14:52 and then sends the data packets to
00:14:53 my Cloud Gateway. This means that
00:14:56 we only set up one route here. The Pi
00:14:57 takes over the VPN, because this box

*Abstract:* This video analyzes a breaking Wall Street Journal report detailing an alleged letter sent by Donald Trump to Jeffrey Epstein for his 50th birthday in 2003. The report claims the letter, part of a larger album, contained a drawing of a naked woman and a typewritten note with incriminating phrases like "enigmas never age" and a reference to a shared "wonderful secret." The video examines Trump's vehement denial of the story, his claim that he doesn't draw, and his threat to sue the publication. It then presents corroborating circumstantial evidence, including the fact that other individuals mentioned in the article did not deny their letters, archived proof of the named bookbinder's connection to Epstein, and public records of Trump creating "doodles" for charity. The narrator argues that Trump's recent strange behavior regarding the Epstein files and his call to release grand jury transcripts (a potential distraction from the physical evidence) suggest he is concerned about what the files contain. The video concludes by urging caution against jumping to conclusions, emphasizing the need for the definitive evidence—the letter itself—to be made public. *Analyzing the Explosive Allegations Against Trump* * *0:00:02 The Explosive Allegation:* The Wall Street Journal published a story about a letter Donald Trump allegedly sent to Jeffrey Epstein for his 50th birthday in 2003. The letter reportedly featured a drawing of a naked woman and a poem about a "wonderful secret" they shared. * *0:00:43 Trump's Preemptive Behavior:* The video contextualizes the story by highlighting Trump's recent and strange behavior, where he has preemptively dismissed the unreleased Epstein files as "phony stuff" and a "hoax." * *0:02:02 The Letter's Incriminating Content:* The alleged typewritten note within the drawing contains several troubling phrases, including "enigmas never age" and the closing line, "may every day be another wonderful secret." * *0:03:32 Trump's Strong Denial:* In an interview with the Journal, Trump firmly denied writing the letter or drawing the picture, calling it a "fake thing," stating it wasn't his language, and threatening a lawsuit. * *0:05:01 Corroborating Evidence via Others:* While Trump is the only person to issue a firm denial, other individuals mentioned in the WSJ article as having written letters for the same birthday album, such as Alan Dershowitz, gave non-denial responses. * *0:06:36 Contradicting the Denial:* The video presents evidence that Trump has created and donated marker "doodles" for charity auctions in the past, directly contradicting his claim that "I don't draw pictures." This is compared to Prince Andrew's discredited "no sweat" denial. * *0:08:35 The Bookbinder Connection:* A key claim in the WSJ report—that the album was made by bookbinder Herbert Weitz—is corroborated by a 2003 archived version of the bookbinder's website, which lists Jeffrey Epstein as a client. * *0:12:40 A Call for Real Evidence:* In response, Trump has called on his potential AG to release grand jury transcripts. The narrator argues this is a distraction, as the central piece of evidence is the physical letter and album, which would not be in a transcript. * *0:14:51 A Call for Caution and More Proof:* The video concludes by urging viewers not to immediately dismiss or accept the story. While there is significant corroborating circumstantial evidence, the definitive proof—a photo of the letter itself—has not been released by the Wall Street Journal or the DOJ.

The green LED looks different from the others and uses phosphor conversion because of the "green gap" problem where green InGaN emitters suffer efficiency droop at high currents. Phosphide based emitters don't start becoming efficient until around 600nm so also can't be used for high power green emitters. See the paper and plot by Matthias Auf der Maur in his 2015 paper on alloy fluctuations in InGaN as the cause of reduced external quantum efficiency at longer (green) wavelengths.

Narrowband filters we use in Astronomy (Astrophotography) are sided- they work best passing light in one direction so I guess the arrows on the filter frames indicate which way round to install them in the filter wheel.

The smearing on the image could be due to the fact that you don't use a shutter, so you see brighter stripes under bright areas of the image as you still iluminate these pixels while the sensor data ist shifted out towards the top. I experienced this effect back at university with a LN-Cooled CCD for Spectroscopy. The stripes disapeared as soon as you used the shutter instead of disabling it in the open position (but fokussing at 100ms integration time and continuous readout with a focal plane shutter isn't much fun).

The red LED reminds me of one from Roithner Lasertechnik. I have a Symbol 2D scanner which uses two very bright LEDs from that company, one red and one red-orange. The red-orange is behind a lens which focuses it into an extremely narrow beam.

The pricing on that sensor is about right, I looked in to these many years ago when they were still in production since it's the only large sensor you could actually buy. Really cool to see one in the wild.

Maybe the camera should not be illuminated during readout.
From the datasheet of the sensor (Onsemi): saturation 40300 electrons, read noise 12.5 electrons per pixel @ 18MHz (quite bad). quantum efficiency 62% (if it has micro lenses), frame rate 1 Hz. lateral overflow drain to prevent blooming protects against 800x (factor increases linearly with exposure time) saturation exposure (32e6 electrons per pixel at 4ms exposure time), microlens has +/- 20 degree acceptance angle
i guess it would be good for astrophotography

so I've stripped all the bits of the
0:01
optical system so basically we've got
0:03
the uh the camera
0:05
itself which is mounted on this uh very
0:09
complex
0:10
adjustment thing which obviously to set
0:13
you the various tilt and uh alignment
0:15
stuff then there's two of these massive
0:18
lenses I've taken one of these apart I
0:20
think there's something like about eight
0:22
or nine Optical elements in here these
0:25
don't seem to do a great deal in terms
0:26
of electr magnification they're obiously
0:28
just about getting the image to where it
0:29
uh where it needs to be just so that
0:33
goes like that then this Optical block I
0:36
originally thought this was made of some
0:37
s crazy heavy material but it's just
0:39
really the sum of all these Optical bits
0:41
are just ridiculously heavy those lenses
0:43
are about 4 kilos each and then there's
0:45
this very heavy very solid um piece that
0:47
goes in the middle and this is so this
0:49
is the filter wheel assembly with a
0:51
hilariously oversized steper
0:53
motor driving this wheel with these very
0:57
large narrow band filters so we've got
1:00
various different shades of uh
1:03
filters there five Al together that
1:06
one's actually just showing up a silver
1:07
that's actually a a red but fairly low
1:10
transmission orangey red blue green
1:15
there's an excess cover on this side so
1:16
the filters can be accessed and changed
1:19
without taking anything else apart even
1:21
this is like ridiculous it's like solid
1:23
aluminium this is just basically a cover
1:25
the actual wavelengths of these are um
1:27
488 525 570 630 and 700 NM not sure what
1:32
the suffix on that perhaps that's the uh
1:34
the width of the spectral line say these
1:37
are very narrow band filters most of
1:39
them are you very little light through
1:41
so it's still very tight narrow band to
1:43
match the um fluoresence of the dies
1:45
they're using in the biochemical process
1:48
and obviously to reject the light that's
1:49
being fired at it from that Illuminator
1:51
box and then there's a there's a second
1:53
one of these lenses then the actual sort
1:55
of samples below that so uh very serious
1:58
amount of very uh chunky heavy Optics
2:01
okay let's take a look at this light
2:02
source made by company Lumen Dynamics
2:04
who are now part of
2:06
excelitas self-contained unit power
2:08
connector USB and this which one of the
2:11
Cable Bundle said was a TTL interface
2:14
USB wasn't used in uh the fluid
2:17
application output here and I think this
2:19
is an input for um light feedback I
2:21
don't if it's regulated or just a measur
2:23
measurement facility and the uh fiber
2:27
assembly
2:29
Square Inlet there and then there's two
2:32
outputs which have uh lens assemblies
2:35
and this small one which goes back into
2:37
that small Port just Loops out of here
2:40
straight back in So on this side we've
2:42
got the electronics which look pretty
2:44
straightforward we've got a bit of power
2:45
supply stuff over here and we've got
2:48
separate drivers for each wavelength now
2:50
interesting this is clearly been very
2:52
specifically made for this application
2:54
you I was half expecting like say some
2:56
generic drivers that could be used for a
2:58
number of different things but actually
3:00
literally specified the exact wavelength
3:02
on the PCB there is provision here for
3:04
385 NM which isn't populated but this is
3:07
clearly been designed very specifically
3:09
so these four drivers look the same but
3:10
then there's two higher power ones for
3:12
575 and
3:14
520 a slightly bigger heat sink on this
3:16
575 section there a p 24 which is
3:20
providing USB interface USB isolator the
3:23
USB interface just presents as a comport
3:26
I did have a quick look but I didn't
3:27
actually get anything sensible um I did
3:29
dump the Pi code out and there's a few
3:31
you a few sort of commands that you
3:32
could see in text but I didn't actually
3:34
manage to get it working properly I
3:36
found some software for related version
3:38
but it didn't seem to want to talk to it
3:39
but um I say that wasn't used for the
3:41
original application it might be quite
3:42
interesting to get try and get the Run
3:44
hours count out of it and the TTL
3:46
interface looks fairly straightforward
3:48
we've got positions for six opto
3:50
isolators but only five five are
3:52
installed so that corresponds with the
3:54
unused thing so I think this hopefully
3:56
should be as simple as just providing a
3:57
ttrl signal for each color to uh enable
4:00
it a big heat sink here which is there I
4:03
think there's like a big S of metal
4:04
plate through the middle of this that
4:05
all the leads are mounted on the other
4:07
side so this is heat sinking it with a
4:09
air flow from a uh just a fan in here
4:13
obviously don't have the air flow
4:14
anywhere near the Optics so conduction
4:17
cool through to this plate that's then
4:18
uh air cooled got some pots which are
4:21
presumably power
4:22
adjustments okay let's take a look at
4:24
the other side which is uh much more
4:27
interesting see we've got some uh very
4:31
uh neatly Twisted cable assemblies there
4:35
a bunch of leads so we've got one here
4:37
475 up here 430 NM 630 575 and 520
4:44
filters and dcro mirrors a quick way to
4:48
see what's white is if we just shine
4:49
some white light through
4:51
here not sure how it is is to see on the
4:54
camera but shining white light we do
4:55
actually get a bit of red a bit of blue
4:57
some yellow here so the obstacle path
5:00
575 it goes sort of here bounces off
5:03
this mirror and goes out the 520 goes
5:07
sort of down here across here and up
5:09
there 630 goes basically straight
5:13
through
5:15
430 goes across there down there along
5:17
there and the 475 goes down here and
5:20
left this is the light sensing thing
5:22
think here there's just a um I think
5:24
there a photo diode or other sensor
5:26
haven't actually taken that off and
5:28
everything's fixed down to this chunk of
5:31
aluminium which acts as the heat
5:32
spreader that then conducts the heat to
5:33
the back side for the heat
5:35
sink and the actual lead packages all
5:38
look fairly similar except for this one
5:41
on the 575 which looks quite a bit more
5:44
substantial big spay
5:46
Terminals and the interface for this
5:48
turned out to be extremely simple it's
5:50
literally a 5V TTL level to enable each
5:54
color doesn't seem to be any tensity
5:56
control but there are some additional
5:58
pins on that connector that weren't used
5:59
in the through time thing so maybe
6:01
there's some extra lines that control
6:02
that I couldn't find any data on this uh
6:05
unit and the um their current product
6:07
range is quite significantly different
6:09
so we've got the uh blue these
6:13
might may well be saturating the camera
6:16
so they might look a bit weird so that's
6:17
the 430
6:18
blue the 575
6:24
yellow uh
6:26
475 light blue
6:29
the uh 520
6:31
green and the uh 630 red now one
6:36
interesting thing I noticed for the
6:39
575 it's actually it's actually using a
6:42
white lead and then filtering it rather
6:44
than using all the other ones are using
6:46
leads which are the fundamental colors
6:47
but uh this is actually doing white and
6:50
it's a combination of this filter and
6:52
the dichroic mirrors that are turning to
6:55
Yellow if we take the filter out and a
6:57
lot of the a lot of the um blue content
7:00
is going this way the red is going
7:02
straight through these two mirrors so
7:05
this is clearly not reflecting much of
7:08
that so we end up with the yellow coming
7:10
out of uh out of there which is a fairly
7:14
light yellow color which you don't
7:16
really see from high intensity leads so
7:19
that's clearly why they've used the
7:20
white to uh do this power consumption of
7:23
the white is pretty high so going up to
7:25
about 2 and 1 half amps on that color
7:27
whereas most of the other colors are
7:28
only drawing half an amp or so at 24
7:30
volts the uh the green is up to about
7:32
1.2 but say this thing is uh much
7:35
brighter and if you actually run all the
7:38
colors at the same time you get a fairly
7:41
reasonable um looking white coming out
7:43
of it and one thing you might just be
7:45
out to notice is there is some sort
7:46
color banding around here that's not
7:49
getting uh everything s completely
7:51
concentric and I think that's where this
7:53
fiber optic thing comes
7:58
in I'll
8:00
get a couple of Fairly accurately shaped
8:04
very sort of uniform color and looking
8:06
at What's um inside here we've basically
8:09
just got this Square Rod so this is
8:12
clearly yeah the lights just bouncing
8:13
off all the all the various sides to um
8:16
get a nice uniform illumination uh this
8:19
back bit looks like it's all potted so
8:21
nothing I really do to get in there I
8:24
think this is fiber so I have come
8:26
across um cables like this which are
8:27
liquid fill but just looking through the
8:30
end of this it's probably a bit hard to
8:31
see it does look like there fiber ends
8:34
going going on there and so there's this
8:36
feedback thing which is just obviously
8:39
compensating for the any light losses
8:41
through here to get an accurate
8:43
representation of uh the light that's
8:45
been launched out of these two
8:47
fibers and you see uh
8:49
these have got this sort of trapezium
8:54
shape light guides again it's like a
8:56
sort of acrylic or glass light guide
9:00
guess projected just to make the right
9:03
rectangular
9:04
shape and look at this Center assembly
9:07
um the light output doesn't uh change
9:10
whether you feed this in or not so it's
9:11
clear not doing any internal Clos Loop
9:14
control obviously there may well be some
9:16
facility for it to do that but it's not
9:17
being used in this
9:19
application and so this output just
9:21
produces a voltage on the uh outle
9:24
connector proportional to the amount of
9:26
light that's present so there's a little
9:28
diffuser in the back there
9:30
and then there's just some kind of uh
9:33
Optical sensor looks like a
9:35
chip looking at the lead it's a very
9:37
small package on the PCB with this lens
9:40
assembly over the top and these look
9:43
like they're actually on a copper
9:44
Metalized PCB for maximum thermal
9:47
performance and yeah it's a very small
9:49
package looks like it's a ceramic
9:51
package and there's a thermister there
9:53
for temperature monitoring this is the
9:56
475 blue one this is the 520 need to
9:59
Green which is uh rather different OB
10:02
it's a much bigger D with lots of bond
10:04
wise but also this looks like it's using
10:05
a phosphor if I shine a blue light at it
10:08
lights up green so this is actually a
10:10
phosphor conversion green lead which
10:12
I've I've come across before they want
10:15
that specific wavelength so they may be
10:17
easier to tune a phosphor than tune the
10:20
um semiconductor material to get the uh
10:23
right right wavelength from the lead
10:24
directly uh red 630 similar size to the
10:28
blue one or does seem to have a uh a
10:31
lens on top of it there is a sort of red
10:33
coloring to
10:35
the die but that doesn't appear to be
10:38
fluorescent as far as I can
10:39
tell and the white one again a little
10:41
bit different sort of much higher
10:43
current
10:46
connectors a makeer name on that
10:48
connector flot light not sure if that's
10:52
the connector or the lead
10:54
itself and obviously with the phosphor
10:56
and I'd imagine that phosphor may well
10:58
be tuned to get the maximum to the uh 5
11:01
cenm and actually this white one looks
11:04
like a St fairly standard product I just
11:06
found it in Mouse made by luminous
11:09
devices in fact actually I think all
11:11
these are based on various luminous
11:13
devices modules and they're you take
11:17
looks like they taking the nearest
11:18
wavelength and then just using these
11:19
filters to clean it up to get a precise
11:22
uh spectral line out of it so quite a
11:25
nice neat and um extreme
11:30
bright light source uh sure I've got any
11:33
particular use for it so I think this
11:35
might end up on
11:36
eBay but uh very pretty to look out and
11:40
without the uh risk of burning your eyes
11:43
out like you do with lasers so I thought
11:45
it would be interesting to try and
11:46
figure out the runtime of this things
11:48
like this we usually keep some sort
11:49
record of runtime cuz leads degrade over
11:51
time I couldn't get any software to work
11:52
through the USB face but then had a
11:54
thought probably going to be writing the
11:55
runtime periodically to the e s prom so
11:58
I just just scope up that and noticed it
12:00
was doing right every 5 minutes so I
12:02
just ran it for a while periodically
12:04
reading the E squ I just held the pick
12:05
in in reset and um put clip over to read
12:07
the square prom and found it was writing
12:10
one location per color every 5 minutes
12:12
so if one color was on it would write
12:14
that location every 5 minutes and just
12:16
increment it by one so after doing a few
12:18
tests with different colors of different
12:19
time periods it looked extremely
12:21
straightforward it's like a four bite
12:22
count for each color looking at the
12:24
original data that was in it all the
12:26
colors apart from Green were reading
12:28
zero and the green was reading four
12:30
indicating a total 20 minutes run time
12:32
ever if it was turned on run for a short
12:34
time then turned off that might not have
12:36
been counted but even so indicates this
12:37
thing wasn't used a great deal the whole
12:40
s process of doing a run can be several
12:42
hours but it'll only be doing probably
12:43
the Imaging at the end of that so you
12:46
wouldn't expect to be running for a long
12:47
time but say a single color for 20
12:50
minutes over its whole lifetime does
12:52
seem a little bit on the low side okay
12:55
let's look at the camera un fortunately
12:57
I managed to not record any sound when I
12:58
did this it's also a couple of months
13:00
ago so there's going to be a few details
13:02
that I've forgotten so I'm just going to
13:04
dub this over the original footage so um
13:07
take the lid off see this massive great
13:10
heat sink so this is a pel cool camera
13:12
we've got this blower fan producing a
13:14
fair amount of air flow through
13:16
it the connector here there's the ccds
13:19
mounted on the board on the
13:24
right this unplugs so we've got a bit of
13:27
power supply stuff on here
13:29
USB interface I think that's the Cyprus
13:32
microcontroller High speeded USB
13:34
interface there's a zyink spon fpga some
13:40
RAM and there's a couple of ATD
13:42
converters can't quite read what those
13:45
those are but anal
13:47
devices um little bit of bodgery around
13:51
here extra decoupling obviously they
13:53
have having some noise issues this is
13:55
around the ram chip quite a lot of extra
13:57
capacitors been added there
13:59
uh there's a couple of amplifiers prior
14:01
to the HD converter buffers or Andor
14:05
amplifiers taking the CCD
14:08
signal um bit more power spy stuff here
14:11
this is probably all to do with
14:12
generating the various CCD bias voltages
14:14
they uh need quite a lot of exotic
14:18
voltages next board down is just a
14:20
shield and an interconnect
14:24
boardly shielding the power supply stuff
14:26
from some the more sensitive an log
14:28
stuff
14:31
and this is the bottom board which is
14:32
just all power supply
14:34
stuff as you can see tons of capacitors
14:37
or Transformer in
14:42
there and this is the CCD which is a uh
14:47
very impressive thing this is a kf50 100
14:50
originally by true sense then codec
14:53
there ON
14:54
Semiconductor it's 50 megapixels uh the
14:58
only price I could find was this one
15:00
5,000 bucks and the architecture you can
15:03
see there actually two separate halves
15:04
which explains the Dual AZ converters
15:06
and two amplifiers it's literally split
15:08
down the middle and duplicated so it's
15:10
outputting two streams in parallel just
15:13
to keep the bandwidth sensible and it's
15:15
got this amazing um diffraction effects
15:18
it's got micro lenses over the pixel so
15:20
there's there's a bit more Optics going
15:22
on than on a normal
15:25
sensor few more bodges on the CCD board
15:28
including this wire which isn't really
15:29
tacked down very well which is a bit uh
15:32
bit of a mess quite a few bits around
15:34
this board where they've uh tacked
15:36
various bits on which is not super
15:38
impressive looks like CCD drivers on the
15:40
left with those 3 ohm um damping
15:43
resistors on the
15:47
output get a few more little bodges
15:50
around here some of
15:52
the and there's this separator the
15:54
silica gel to keep the moisture down but
15:56
there's this separator that actually
15:58
appears to be cut from piece of
15:59
antistatic
16:04
bag and this sort of thermal block on
16:06
top of this stack of three pel Cola
16:12
modules so as with any Stacks they get
16:16
um larger as they go back towards the
16:18
heat sink because each P's got to not
16:20
only take the heat from the previous but
16:21
also the waste heat which is quite
16:27
significant you see a little temperature
16:29
sensor here that copper block which
16:32
makes contact with the back of the
16:37
CCD and this's the back of the
16:40
pelas this then contacts the heat sink
16:44
on the uh rear there a few thermal pads
16:46
as well for some of the other power
16:47
components on this
16:51
PCB okay I've connected this uh camera
16:54
up I found some drivers on the disc that
16:56
seem to work under Windows 7 couldn't
16:58
get to install under Windows 11 though
17:01
um in the absence of any sort of lens or
17:03
being bothered to the proper amount I've
17:04
just put some f over it and put a little
17:06
pin in there to make a pinhole lens and
17:08
software gives a few options I'm not
17:11
entirely sure what all these are there's
17:12
obviously a clock frequency 22 MHz low
17:15
gain and with PFG no idea what that is
17:19
something something game programmable
17:20
Something game perhaps ver exposure
17:23
types I think focus is just like a
17:25
continuous grab until you tell it to
17:27
stop not entirely sure all these options
17:30
are obviously exposure time uh triggers
17:33
there ex external hardware trigger inut
17:35
you just trigger using a um thing on
17:37
screen so the resolution is 8176 by
17:40
6132 and you can actually bin those
17:42
where you combine multiple pixels to get
17:46
increased gain at the expense of lower
17:48
resolution down this is a 10sec exposure
17:51
obviously of the pin hole it's very uh
17:53
intensitive so we just stand still now
17:56
downloading it there's the uh exposure
17:59
so when it's
18:01
um there's a little status thing down
18:03
here so that tells you the um exposure
18:07
[Applause]
18:09
time it's this is just it
18:15
downloading um it is quite I'm seeing
18:18
quite a lot like smearing I think that I
18:20
don't know whether that's just due to
18:21
pixels overloading or something else I
18:24
mean yeah it's not it's not um out of
18:26
the question that there's something not
18:27
totally right about this camera
18:28
certainly was bodge wise on there um I
18:31
don't I'd imagine a camera like this
18:32
it's got a fairly narrow range of
18:34
intensities that it's happy with I'm not
18:36
going to spend a great deal of time on
18:38
this if you're interested in this camera
18:40
maybe for astronomy or something and
18:42
happy to sort of take the risk of it may
18:44
not be uh perfect I'll um I think I'll
18:47
stick this on eBay along with the
18:48
Illuminator I'll put a link down in the
18:50
description to the listing take your
18:52
chances to grab a bargain so for example
18:54
here we see this vertical streaking so
18:56
I'm not sure how normal that is this is
18:58
on fairly bright scene looking out the
19:02
window if I cut the exposure time down
19:04
on that it's now 1 second
19:07
exposure again most of the image
19:09
disappears again this is looks like it's
19:11
possibly over still overloading here go
19:14
that go down to say say quarter a
19:16
second so again I think there might be
19:19
some Auto gain control going on here um
19:21
this is with the PFG option let's try
19:23
turning that off and see what
19:25
happens so I'm not sure this is actually
19:27
more streaking or which just it's
19:29
cranked up the gain all the dis display
19:31
gray scale to show what um you know the
19:33
range of things that it's captured
19:36
there's one of one of 12 things in the
19:38
software there's um you can see of you
19:40
can't seem to read out the temperature
19:42
of the pelta cooler but you can set the
19:44
temperature and if you said it's a
19:46
different temperature you see the power
19:48
consumption jump up running the cooler
19:50
to get the temperature you requested but
19:52
I can't see anything anywhere that tells
19:54
you whether the cool is at the at the
19:56
temperature other than the power
19:57
consumption going down and there's no
19:59
temperature read out
20:03
here and just some yeah this is just
20:05
sort of very basic software I'm sure
20:07
there's like an API for more
20:09
sophisticated
20:10
applications but so if you know anything
20:12
more about these cameras please um stick
20:14
in the
20:15
comments um incidentally when I was
20:18
editing I didn't notice there was a bent
20:19
pin on the um CCD but I did fix that
20:22
before doing these tests and also
20:24
reactivated the um silica gel desicant
20:26
cuz I noticed it was uh I was getting
20:28
bit of condensation on the window but um
20:31
yeah so a couple of uh interesting but
20:34
maybe not particularly uh useful pieces
20:37
of Kit except for someone that's got a
20:38
very specific use so um I'll stick a
20:42
I'll stick these on eBay put a link in
20:44
the description and say hopefully
20:45
someone could actually make some uh good
20:47
use of these things
Example Output:
**Abstract:**
This video presents Part 2 of a teardown focusing on the optical components of a Fluidigm Polaris biotechnology instrument, specifically the multi-wavelength illuminator and the high-resolution CCD camera.
The Lumen Dynamics illuminator unit is examined in detail, revealing its construction using multiple high-power LEDs (430nm, 475nm, 520nm, 575nm, 630nm) combined via dichroic mirrors and filters. A square fiber optic rod is used to homogenize the light. A notable finding is the use of a phosphor-converted white LED filtered to achieve the 575nm output. The unit features simple TTL activation for each color, conduction cooling, and internal homogenization optics. Analysis of its EEPROM suggests extremely low operational runtime.
The camera module teardown showcases a 50 Megapixel ON Semiconductor KAF-50100 CCD sensor with micro-lenses, cooled by a multi-stage Peltier stack. The control electronics include an FPGA and a USB interface. Significant post-manufacturing modifications ("bodges") are observed on the camera's circuit boards. Basic functional testing using vendor software and a pinhole lens confirms image capture but reveals prominent vertical streaking artifacts, the cause of which remains uncertain (potential overload, readout artifact, or fault).
**Exploring the Fluidigm Polaris: A Detailed Look at its High-End Optics and Camera System**
* **0:00 High-End Optics:** The system utilizes heavy, high-quality lenses and mirrors for precise imaging, weighing around 4 kilos each.
* **0:49 Narrow Band Filters:** A filter wheel with five narrow band filters (488, 525, 570, 630, and 700 nm) ensures accurate fluorescence detection and rejection of excitation light.
* **2:01 Customizable Illumination:** The Lumen Dynamics light source offers five individually controllable LED wavelengths (430, 475, 520, 575, 630 nm) with varying power outputs. The 575nm yellow LED is uniquely achieved using a white LED with filtering.
* **3:45 TTL Control:** The light source is controlled via a simple TTL interface, enabling easy on/off switching for each LED color.
* **12:55 Sophisticated Camera:** The system includes a 50-megapixel Kodak KAI-50100 CCD camera with a Peltier cooling system for reduced noise.
* **14:54 High-Speed Data Transfer:** The camera features dual analog-to-digital converters to manage the high data throughput of the 50-megapixel sensor, which is effectively two 25-megapixel sensors operating in parallel.
* **18:11 Possible Issues:** The video creator noted some potential issues with the camera, including image smearing.
* **18:11 Limited Dynamic Range:** The camera's sensor has a limited dynamic range, making it potentially challenging to capture scenes with a wide range of brightness levels.
* **11:45 Low Runtime:** Internal data suggests the system has seen minimal usage, with only 20 minutes of recorded runtime for the green LED.
* **20:38 Availability on eBay:** Both the illuminator and camera are expected to be listed for sale on eBay.
Here is the real transcript. Please summarize it:
00:00:02 It's all coming out today. The Wall
00:00:02 Street Journal not only released an
00:00:03 article today they're getting sued as
00:00:04 well for this article about Donald
00:00:06 Trump's connection to Jeffrey Epstein.
00:00:08 It's explosive. It's about a letter
00:00:10 Trump sent to Epstein with supposedly a
00:00:13 drawing of a naked woman by Trump along
00:00:17 with a little poem which talks about a
00:00:19 wonderful secret that Jeffrey Epstein
00:00:21 and Trump share. We will go through all
00:00:23 the evidence because there's a lot to
00:00:25 this. You are very silly if you jump to
00:00:28 conclusions on a story this big with
00:00:31 this wide of implications. Let's set the
00:00:34 stage because we're going to take our
00:00:35 time going through this. The president's
00:00:37 behavior during the runup to this
00:00:40 Epstein file leak has been absolutely
00:00:43 strange.
00:00:43 Are you still talking about Jeffrey
00:00:45 Epstein?
00:00:46 It's pretty boring stuff. It's sorted
00:00:48 but it's boring.
00:00:49 You don't want to affect people's lives
00:00:50 if it's phony stuff in there cuz it's a
00:00:52 lot of phony stuff. You know, these
00:00:54 files were made up by Comey. They were
00:00:56 made up by Obama.
00:00:57 Even his supporters are like, "Well, why
00:01:00 is he acting this way? It's so weird.
00:01:02 All of a sudden, it goes from the files
00:01:04 exist to they don't exist to they're a
00:01:06 hoax actually, and there's a bunch of
00:01:08 phony stuff in there." This article, if
00:01:12 true, explains a lot of the strange
00:01:15 behavior. And we don't know if there's
00:01:17 more that's going to come out, if this
00:01:19 is all there is. But I'm going to go
00:01:20 through the main allegation, and I will
00:01:21 call it an allegation because Trump is
00:01:23 definitely going to sue over this. He's
00:01:25 already said as much. So, here's
00:01:27 basically the story. Supposedly, Gizlain
00:01:29 Maxwell collected letters from Trump and
00:01:32 dozens of Epstein's associates for a
00:01:34 2003 birthday album. It was for his 50th
00:01:37 birthday. Pages from the leatherbound
00:01:39 album assembled before Epste was first
00:01:40 arrested are among the documents
00:01:42 examined by the Department of Justice
00:01:44 officials. So there are birthday letters
00:01:46 to Epstein that supposedly have been
00:01:48 seen by the DOJ. They have them in their
00:01:51 files. And the one from Trump supposedly
00:01:54 has a naked woman which appears to be
00:01:56 handdrawn with a heavy marker. And the
00:01:58 future president's signature is a
00:02:00 squiggly Donald below her waist. The
00:02:02 Wall Street Journal goes on to say,
00:02:03 "It's not clear how the letter with
00:02:05 Trump's signature was prepared inside
00:02:07 the outline of the naked woman was a
00:02:08 typewritten note stopped as an imaginary
00:02:10 conversation between Trump and Epstein."
00:02:12 Voiceover, there's more to life than
00:02:14 having everything. Donald, yes, there
00:02:17 is, but I won't tell you what it is.
00:02:19 Jeffrey, nor will I since I also know
00:02:21 what it is. Donald, we have certain
00:02:24 things in common, Jeffrey. Yes, we do.
00:02:26 Come to think of it, enigmas never age.
00:02:29 Have you noticed that? As a matter of
00:02:31 fact, it was clear to me the last time I
00:02:33 saw you. And the final line is, "A pal
00:02:35 is a wonderful thing. Happy birthday,
00:02:37 and may every day be another wonderful
00:02:40 secret." Obviously, that is an insane
00:02:42 thing to write to what later would be
00:02:45 found out to be one of the world's most
00:02:46 prolific.
00:02:48 But there's also two lines in there
00:02:50 which are horrendous. One, enigmas never
00:02:54 age. That's just a strange line. It's a
00:02:57 very incriminating sounding line. We
00:02:59 don't know what it means exactly. And
00:03:00 then also we see may every day be
00:03:02 another wonderful secret. Of course,
00:03:05 this all written inside the outline of a
00:03:07 naked woman uh kind of tells you what
00:03:10 secret they may be talking about there.
00:03:12 Now, we're going to go over Trump's
00:03:14 response and then of course all the
00:03:16 evidence, all the denials, what you may
00:03:19 want to know before making up your mind.
00:03:21 Like I said, this is not a story where
00:03:23 you're going to want to snap to
00:03:24 judgment. Even now, I I'm still I think
00:03:27 there's still a lot we need to see. But
00:03:30 I want to go over Trump's response. He
00:03:32 gave an interview with the Journal on
00:03:34 Tuesday evening, and he denied writing
00:03:36 the letter or drawing the picture.
00:03:37 Quote, "This is not me. This is a fake
00:03:38 thing. It's a fake Wall Street Journal
00:03:40 story. I never wrote a picture in my
00:03:43 life. I don't draw pictures of women."
00:03:45 He said, "It's not my language. It's not
00:03:47 my words." He told the journal he was
00:03:49 preparing to file a lawsuit if it
00:03:50 published the article. I'm going to sue
00:03:51 the Wall Street Journal just like I sued
00:03:53 everyone else. What do we make of this?
00:03:55 Before we jump into the evidence, before
00:03:56 we jump into all the reactions, both
00:03:59 public and of the people involved, let's
00:04:01 just talk about what this could mean.
00:04:04 The denial puts Trump in a very
00:04:06 particular position because if it later
00:04:09 comes out and turns out to be true, it's
00:04:12 worth saying the Wall Street Journal did
00:04:13 not publish a photo of the letter, which
00:04:16 everyone's been asking for. There are a
00:04:18 lot of reasons not to publish it. Maybe
00:04:19 your source didn't allow it, but that's
00:04:22 a huge part that could come out that
00:04:24 changes the whole landscape of this,
00:04:25 right? If it comes out, it's very
00:04:28 devastating because you wouldn't lie
00:04:30 about something like this if you thought
00:04:32 it was no big deal, right? The denial
00:04:34 actually implies a lot of bad things
00:04:37 about what the letter could mean. If you
00:04:40 weren't worried about a story like this,
00:04:42 if you thought the letter was a, you
00:04:43 know, nothing, you wouldn't deny it. You
00:04:45 would just give no comment. You
00:04:47 certainly wouldn't give an interview.
00:04:48 So, now we're going to talk about the
00:04:49 reactions of the people involved because
00:04:51 it's worth saying Trump is not the only
00:04:54 letter mentioned in here. And I think
00:04:55 that's really important because in a
00:04:57 story like this, you want to look to
00:04:58 what could be corroborating evidence.
00:05:01 So, Alan Derswitz is cited in the piece
00:05:04 having written a letter that included a
00:05:06 mockup of a vanity unfair magazine with
00:05:09 mock headlines of who was Jack the
00:05:11 Ripper? Was it Jeffrey Epstein? Allen, a
00:05:14 former lawyer for Epstein, does not deny
00:05:16 this. He says, "It's been a long time
00:05:18 and I don't recall the content of what I
00:05:20 may have written." Lex Wexner also
00:05:22 supposedly had a letter in there. He
00:05:23 declined a comment. Supposedly, his
00:05:25 letter was, "I wanted to get you what
00:05:27 you want." So, here it is. After the
00:05:28 text was a line drawing of what appeared
00:05:30 to be a woman's breast. And then we have
00:05:32 a former assistant who was not cited who
00:05:35 sent Jeffrey a letter. Oh, Jeffrey of
00:05:37 Jeffrey. Everyone loves you. Fun in the
00:05:39 sun. Fun just for fun. Pretty innocuous.
00:05:42 And then of course we have Donald Trump
00:05:44 who denies of course the whole thing. So
00:05:47 we have some non-denials, some people
00:05:49 who just didn't respond. And then we
00:05:51 have Trump. Trump's the only one who's
00:05:52 firmly denying this letter so far with
00:05:55 him doubling down on Truth Social saying
00:05:57 it's not my words. It's not the way I
00:05:59 talk. Also, I don't draw pictures. I
00:06:02 told Rupert Murdoch it was a scam and he
00:06:04 shouldn't print this fake story, but he
00:06:05 did. And now I'm going to sue him in his
00:06:07 third rate newspaper. Now, a couple
00:06:09 comments quick on that one. The Wall
00:06:12 Street Journal is not a third-rate
00:06:13 newspaper. It's also not a super
00:06:15 left-leaning newspaper. Not that that
00:06:18 should matter in journalism, but I know
00:06:20 people's media literacy, that stuff kind
00:06:22 of does kind of tip off their signals.
00:06:24 It's unlikely they're going to publish
00:06:26 something they know they're going to get
00:06:27 sued for unless they have something. And
00:06:30 so, here's where I want to talk about a
00:06:32 little bit of the circumstantial stuff.
00:06:34 So, Trump obviously states, "I don't
00:06:36 draw pictures." But turns out
00:06:40 that's kind of not true. So in a book
00:06:42 called Never Give Up, Trump wrote, "Each
00:06:45 year I donate an autograph doodle to the
00:06:47 Doodle for Hunger auction at Tavern on
00:06:50 the Green. It's a great event." And sure
00:06:51 enough, publicly you can find several
00:06:53 doodles that Donald Trump has done. Most
00:06:56 of these are of skylines, architecture.
00:06:59 None of these are of women. Still, it's
00:07:02 strange to say I don't draw pictures
00:07:04 when you very clearly draw pictures and
00:07:06 they appear to be in thick marker, which
00:07:08 is what you were accused of drawing them
00:07:10 in. Now, none of that means anything,
00:07:12 but it just reminds me a little bit of
00:07:14 the Prince Andrew denial. I don't know
00:07:17 if you guys remember the sweat denial. A
00:07:19 big part of the interview with Prince
00:07:21 Andrew was the denial that he couldn't
00:07:24 have done anything bad because he
00:07:26 couldn't sweat. So this supposedly
00:07:28 falsified Virginia Guprey's whole story.
00:07:31 I I I
00:07:33 have a peculiar medical condition which
00:07:36 is that I don't sweat um or I didn't
00:07:39 sweat at the time.
00:07:40 So yeah, that was kind of this claim
00:07:42 like, hey, this couldn't be true because
00:07:44 I don't do X, but actually we see that
00:07:47 Prince Andrew actually does sweat. And
00:07:50 in the same way, it's not perfect proof,
00:07:53 but you really shouldn't say you don't
00:07:55 draw pictures when being accused of
00:07:57 drawing thick black marker pictures when
00:08:00 uh you definitely draw pictures
00:08:02 sometimes. I mean, it's just and it's
00:08:04 public. I mean, that that's just kind of
00:08:06 a just an obvious devastating hole in
00:08:10 your whole argument. Now, again, I've
00:08:13 got to say like it this is just the
00:08:15 basics. We do not have the letter, okay?
00:08:18 I'm relying on the Wall Street Journal's
00:08:20 reporting on this and we're
00:08:21 corroborating with different pieces of
00:08:24 public evidence. Ultimately, we need to
00:08:26 see if this was actually in the Epstein
00:08:29 files. But there are some other stuff
00:08:31 too that we can look to to corroborate
00:08:33 this story. So, we can look at the
00:08:35 bookbinder. So, in the Wall Street
00:08:37 Journal report, we see a very specific
00:08:39 and interesting corroboration. It says
00:08:41 the book was put together by the New
00:08:43 York City bookbinder Herbert Whites.
00:08:45 According to people involved with the
00:08:46 process, Whites listed Epstein as a
00:08:49 client on his website in 2003. So here
00:08:52 we have a chance to corroborate
00:08:54 externally. Of course, it's not a full
00:08:56 corroboration, but we have a chance to
00:08:58 look to see was it actually on his
00:09:00 website. Right? So if we go to the
00:09:03 archive, we see in 2003 at
00:09:05 whitesman.com,
00:09:07 we see a client list and we see Jeffrey
00:09:10 Epstein is listed on it with a different
00:09:12 spelling of Jeffrey, I should note. And
00:09:15 this says people for whom we have bound
00:09:16 up books and albums. This is another
00:09:19 piece of circumstantial evidence that
00:09:22 makes it hard to believe. It's just
00:09:23 fully made up. Now, you can believe
00:09:26 something in the middle. You can believe
00:09:28 that the letter exists and the Wall
00:09:30 Street Journal saw it and somebody
00:09:32 invented it, right? Like there are a lot
00:09:34 of options here, but the idea that okay,
00:09:37 it the Wall Street Journal is just fully
00:09:39 inventing this story. They're releasing
00:09:41 something with literally no evidence.
00:09:43 They're just fabricating it all. But
00:09:45 citing all these different people,
00:09:47 citing third party stuff that you can
00:09:49 fact check publicly, that's a piece of
00:09:52 evidence to think about. Now, we're
00:09:53 going to talk about the public reactions
00:09:55 to this. We have Caroline Levit, the
00:09:57 press secretary, saying, "The Wall
00:09:59 Street Journal published a hatchet job
00:10:00 with a fake birthday letter that's
00:10:02 supposedly from 2003. This is like the
00:10:05 steel dossier that kickstarted the
00:10:06 Russia Russia hoax all over again. The
00:10:08 Wall Street Journal refused to show us
00:10:09 the letter and conceded they don't even
00:10:10 have it in their possession when we
00:10:12 asked them to verify the alleged
00:10:13 document they're basing their entire
00:10:15 fake story on." Then you have Dan Walin
00:10:18 saying, "The amount of people who think
00:10:19 publications, the scope of the Wall
00:10:20 Street Journal, just put explosive stuff
00:10:22 out about a public figure without
00:10:24 wellestablished authentication
00:10:25 procedures and running it through a team
00:10:27 of lawyers know literally nothing about
00:10:29 journalism." Charlie Kirk says, "This is
00:10:31 not how Trump talks at all. I don't
00:10:34 believe it." Referring to the actual
00:10:36 letter's contents. Specifically, people
00:10:38 picked up on the idea that Trump says
00:10:40 enigma in the writing of it. in fact
00:10:43 Trump writing at all. Some people find
00:10:45 that hard to believe. JD Vance says,
00:10:47 "Forgive my language, but this story is
00:10:49 complete and utter bull." The Wall
00:10:51 Street Journal should be ashamed of
00:10:52 publishing it. Where is the letter?
00:10:53 Would you be shocked to learn they never
00:10:55 showed it to us before publishing it?
00:10:56 Does anyone honestly believe this sounds
00:10:57 like Donald Trump? Of course, then you
00:10:59 have a response to that where somebody
00:11:01 says, "Carson's an enigma to me." This
00:11:04 is clearly debunking the idea that the
00:11:06 word enigma is not in Trump's
00:11:08 vocabulary.
00:11:10 Now, Carson's an enigma to me. So that
00:11:12 clearly debunks the idea that he
00:11:13 couldn't have written this because
00:11:14 enigma wasn't in his vocabulary. It
00:11:17 actually is. So from where I'm sitting,
00:11:19 the letter is odd, but it also is in
00:11:22 line with some of these other letters
00:11:24 from people like Lex Wexner. It's also
00:11:27 in line with some of the doodles that
00:11:30 Trump has publicly made. And it is also
00:11:32 in line with Trump's recent odd behavior
00:11:35 with the Epstein files where he keeps
00:11:37 setting up the idea that there's this
00:11:39 big hoax coming that there's phony stuff
00:11:42 in there. And that actually is the most
00:11:45 persuasive piece of evidence Trump's own
00:11:47 behavior in this weird meltdown more
00:11:50 than anything which has convinced me
00:11:52 because on the one hand there are some
00:11:54 things which would tilt in the favor of
00:11:56 it not being Trump, right? The very fact
00:11:59 that it's a letter. the pros of the
00:12:02 letter is a bit strange and then you
00:12:05 also have the fact that okay if the DOJ
00:12:07 had this during the Biden years why
00:12:10 didn't it come out right so that's all
00:12:12 pretty compelling until you once again
00:12:15 just look at the way Trump has been
00:12:17 behaving I think it strongly suggests
00:12:19 that Trump saw something in the Epstein
00:12:21 files was debriefed on something that he
00:12:24 was worried about whether it was this
00:12:26 letter or something else I don't know
00:12:28 but clearly there's something in those
00:12:30 files that he was concerned about being
00:12:32 involved with. I think we need a full
00:12:35 declassification of these files except
00:12:37 for the CSAM and victims. Now to the
00:12:40 declassifying comment, Donald Trump
00:12:42 based on this has posted based on the
00:12:44 ridiculous amount of publicity given to
00:12:46 Jeffrey Epstein. I have asked AG Pam
00:12:47 Bondi to produce any and all pertinent
00:12:49 grand jury testimony subject to court
00:12:51 approval. This scam should end right
00:12:53 now. And Pam Bondia said, President
00:12:55 Trump, we are ready to move on the court
00:12:57 tomorrow to unseal the grand jury
00:12:59 transcripts. I think that ultimately it
00:13:01 needs to be everything or nothing. You
00:13:03 can't give a little bit at this point
00:13:05 with the level of allegations being
00:13:07 leveled against our president that he
00:13:09 would send pretty incriminating letters
00:13:12 to the world's most notorious
00:13:15 now again before he was arrested the
00:13:18 first time, right? But given the
00:13:19 letter's contents, given that they're
00:13:21 doing so much, they're going to be suing
00:13:22 the Wall Street Journal over this. To
00:13:24 deny it, I think if it turns out to be
00:13:27 true is devastating. I mean, totally
00:13:30 devastating and horrific. And no one
00:13:32 should defend it if it's true. And
00:13:34 that's what we need to find out at this
00:13:36 point. So, I think the answer is clearly
00:13:38 that yes, I would love the Wall Street
00:13:40 Journal to release this photo if they
00:13:42 have it in their possession, if they can
00:13:43 release it from their source. And I
00:13:44 would love for the DOJ to declassify the
00:13:47 actual relevant pieces of this whole
00:13:49 thing because the absolutely central
00:13:52 piece of evidence in this whole story
00:13:54 are these letters which are in a
00:13:56 leatherbound album and supposedly in the
00:13:59 DOJ's possession. That's clearly not
00:14:01 going to be a grand jury transcript.
00:14:03 That's going to be one of the pieces of
00:14:05 evidence they collected from Epstein or
00:14:07 Maxwell. And so that is a different
00:14:10 category altogether. So, I think given
00:14:12 that, it's hard to see this as anything
00:14:14 other than a distraction from what is
00:14:16 actually relevant here, which is, does
00:14:18 this album exist? Yes or no. Show us the
00:14:21 evidence, right? Show us the physical
00:14:23 evidence. Instead, this is just going to
00:14:25 get people riled up because it's an
00:14:27 Epstein release, but it's guaranteed by
00:14:29 definition not to have the evidence one
00:14:32 way or another. A transcript is not
00:14:34 going to have a piece of physical
00:14:35 evidence. And we need to demand answers
00:14:37 on that because either it exists or it
00:14:39 doesn't. And if it does exist, that's a
00:14:42 huge problem. If it doesn't for the Wall
00:14:44 Street Journal, that's a huge problem.
00:14:46 And I'm really not sure which we are
00:14:48 going to get first. All I know is that
00:14:51 if you are looking from the outside, I
00:14:53 would highly recommend that you don't
00:14:55 just dismiss things based on a quick hot
00:14:58 Twitter take. There's a lot to this
00:15:01 story that is corroborating. And also,
00:15:05 we need more evidence on before we can
00:15:07 really make up their mind. And I see a
00:15:09 lot of people have just already written
00:15:10 it off as completely true or completely
00:15:13 false. I think they're not thinking
00:15:15 through the implications of if this is
00:15:17 true, how really crazy it would be if we
00:15:21 live in that world. And then also the
00:15:23 people who are dismissing it as false
00:15:25 right away, you're not really thinking
00:15:27 through like you might be defending a a
00:15:30 right that that is one of the outcomes
00:15:32 that could be true here. We don't know.
00:15:34 Uh and again, even if it is true, we
00:15:37 don't know what is meant by things like
00:15:39 may every day be another wonderful
00:15:42 secret. Uh when calling Jeffrey Epstein
00:15:44 a pal, we wouldn't know what that meant.
00:15:46 But um yeah, it's it's just stunning. So
00:15:49 this report, you absolutely have to
00:15:51 watch it. It is we're going to have a
00:15:53 lot more in the coming days to try to
00:15:55 validate it or falsify it. And we'll see
00:15:58 which one happens first. And yeah,
00:16:01 that's pretty much all I'm prepared to

Thanks Mike. Ooof! - with the level of bodgery going on around 15:48 I think shame would have made me do a board re spin, out of my own pocket if I had to.

The green LED looks different from the others and uses phosphor conversion because of the "green gap" problem where green InGaN emitters suffer efficiency droop at high currents. Phosphide based emitters don't start becoming efficient until around 600nm so also can't be used for high power green emitters. See the paper and plot by Matthias Auf der Maur in his 2015 paper on alloy fluctuations in InGaN as the cause of reduced external quantum efficiency at longer (green) wavelengths.

Yes, but may need a shutter to avoid light during readout

Narrowband filters we use in Astronomy (Astrophotography) are sided- they work best passing light in one direction so I guess the arrows on the filter frames indicate which way round to install them in the filter wheel.

That LED module says it can go up to 28 amps!!! 21 amps for 100%. You should see what it does at 20 amps!

I had an "Oh SHIT!" moment when I realized that the weird trapezoidal shape of that light guide was for keystone correction of the light source.
Very clever.

The smearing on the image could be due to the fact that you don't use a shutter, so you see brighter stripes under bright areas of the image as you still iluminate these pixels while the sensor data ist shifted out towards the top. I experienced this effect back at university with a LN-Cooled CCD for Spectroscopy. The stripes disapeared as soon as you used the shutter instead of disabling it in the open position (but fokussing at 100ms integration time and continuous readout with a focal plane shutter isn't much fun).

The red LED reminds me of one from Roithner Lasertechnik. I have a Symbol 2D scanner which uses two very bright LEDs from that company, one red and one red-orange. The red-orange is behind a lens which focuses it into an extremely narrow beam.

The pricing on that sensor is about right, I looked in to these many years ago when they were still in production since it's the only large sensor you could actually buy. Really cool to see one in the wild.

Maybe the camera should not be illuminated during readout.
From the datasheet of the sensor (Onsemi): saturation 40300 electrons, read noise 12.5 electrons per pixel @ 18MHz (quite bad). quantum efficiency 62% (if it has micro lenses), frame rate 1 Hz. lateral overflow drain to prevent blooming protects against 800x (factor increases linearly with exposure time) saturation exposure (32e6 electrons per pixel at 4ms exposure time), microlens has +/- 20 degree acceptance angle
i guess it would be good for astrophotography

That looks like a finger-lakes filter wheel, however, for astronomy they'd never use such a large stepper.

so I've stripped all the bits of the
0:01
optical system so basically we've got
0:03
the uh the camera
0:05
itself which is mounted on this uh very
0:09
complex
0:10
adjustment thing which obviously to set
0:13
you the various tilt and uh alignment
0:15
stuff then there's two of these massive
0:18
lenses I've taken one of these apart I
0:20
think there's something like about eight
0:22
or nine Optical elements in here these
0:25
don't seem to do a great deal in terms
0:26
of electr magnification they're obiously
0:28
just about getting the image to where it
0:29
uh where it needs to be just so that
0:33
goes like that then this Optical block I
0:36
originally thought this was made of some
0:37
s crazy heavy material but it's just
0:39
really the sum of all these Optical bits
0:41
are just ridiculously heavy those lenses
0:43
are about 4 kilos each and then there's
0:45
this very heavy very solid um piece that
0:47
goes in the middle and this is so this
0:49
is the filter wheel assembly with a
0:51
hilariously oversized steper
0:53
motor driving this wheel with these very
0:57
large narrow band filters so we've got
1:00
various different shades of uh
1:03
filters there five Al together that
1:06
one's actually just showing up a silver
1:07
that's actually a a red but fairly low
1:10
transmission orangey red blue green
1:15
there's an excess cover on this side so
1:16
the filters can be accessed and changed
1:19
without taking anything else apart even
1:21
this is like ridiculous it's like solid
1:23
aluminium this is just basically a cover
1:25
the actual wavelengths of these are um
1:27
488 525 570 630 and 700 NM not sure what
1:32
the suffix on that perhaps that's the uh
1:34
the width of the spectral line say these
1:37
are very narrow band filters most of
1:39
them are you very little light through
1:41
so it's still very tight narrow band to
1:43
match the um fluoresence of the dies
1:45
they're using in the biochemical process
1:48
and obviously to reject the light that's
1:49
being fired at it from that Illuminator
1:51
box and then there's a there's a second
1:53
one of these lenses then the actual sort
1:55
of samples below that so uh very serious
1:58
amount of very uh chunky heavy Optics
2:01
okay let's take a look at this light
2:02
source made by company Lumen Dynamics
2:04
who are now part of
2:06
excelitas self-contained unit power
2:08
connector USB and this which one of the
2:11
Cable Bundle said was a TTL interface
2:14
USB wasn't used in uh the fluid
2:17
application output here and I think this
2:19
is an input for um light feedback I
2:21
don't if it's regulated or just a measur
2:23
measurement facility and the uh fiber
2:27
assembly
2:29
Square Inlet there and then there's two
2:32
outputs which have uh lens assemblies
2:35
and this small one which goes back into
2:37
that small Port just Loops out of here
2:40
straight back in So on this side we've
2:42
got the electronics which look pretty
2:44
straightforward we've got a bit of power
2:45
supply stuff over here and we've got
2:48
separate drivers for each wavelength now
2:50
interesting this is clearly been very
2:52
specifically made for this application
2:54
you I was half expecting like say some
2:56
generic drivers that could be used for a
2:58
number of different things but actually
3:00
literally specified the exact wavelength
3:02
on the PCB there is provision here for
3:04
385 NM which isn't populated but this is
3:07
clearly been designed very specifically
3:09
so these four drivers look the same but
3:10
then there's two higher power ones for
3:12
575 and
3:14
520 a slightly bigger heat sink on this
3:16
575 section there a p 24 which is
3:20
providing USB interface USB isolator the
3:23
USB interface just presents as a comport
3:26
I did have a quick look but I didn't
3:27
actually get anything sensible um I did
3:29
dump the Pi code out and there's a few
3:31
you a few sort of commands that you
3:32
could see in text but I didn't actually
3:34
manage to get it working properly I
3:36
found some software for related version
3:38
but it didn't seem to want to talk to it
3:39
but um I say that wasn't used for the
3:41
original application it might be quite
3:42
interesting to get try and get the Run
3:44
hours count out of it and the TTL
3:46
interface looks fairly straightforward
3:48
we've got positions for six opto
3:50
isolators but only five five are
3:52
installed so that corresponds with the
3:54
unused thing so I think this hopefully
3:56
should be as simple as just providing a
3:57
ttrl signal for each color to uh enable
4:00
it a big heat sink here which is there I
4:03
think there's like a big S of metal
4:04
plate through the middle of this that
4:05
all the leads are mounted on the other
4:07
side so this is heat sinking it with a
4:09
air flow from a uh just a fan in here
4:13
obviously don't have the air flow
4:14
anywhere near the Optics so conduction
4:17
cool through to this plate that's then
4:18
uh air cooled got some pots which are
4:21
presumably power
4:22
adjustments okay let's take a look at
4:24
the other side which is uh much more
4:27
interesting see we've got some uh very
4:31
uh neatly Twisted cable assemblies there
4:35
a bunch of leads so we've got one here
4:37
475 up here 430 NM 630 575 and 520
4:44
filters and dcro mirrors a quick way to
4:48
see what's white is if we just shine
4:49
some white light through
4:51
here not sure how it is is to see on the
4:54
camera but shining white light we do
4:55
actually get a bit of red a bit of blue
4:57
some yellow here so the obstacle path
5:00
575 it goes sort of here bounces off
5:03
this mirror and goes out the 520 goes
5:07
sort of down here across here and up
5:09
there 630 goes basically straight
5:13
through
5:15
430 goes across there down there along
5:17
there and the 475 goes down here and
5:20
left this is the light sensing thing
5:22
think here there's just a um I think
5:24
there a photo diode or other sensor
5:26
haven't actually taken that off and
5:28
everything's fixed down to this chunk of
5:31
aluminium which acts as the heat
5:32
spreader that then conducts the heat to
5:33
the back side for the heat
5:35
sink and the actual lead packages all
5:38
look fairly similar except for this one
5:41
on the 575 which looks quite a bit more
5:44
substantial big spay
5:46
Terminals and the interface for this
5:48
turned out to be extremely simple it's
5:50
literally a 5V TTL level to enable each
5:54
color doesn't seem to be any tensity
5:56
control but there are some additional
5:58
pins on that connector that weren't used
5:59
in the through time thing so maybe
6:01
there's some extra lines that control
6:02
that I couldn't find any data on this uh
6:05
unit and the um their current product
6:07
range is quite significantly different
6:09
so we've got the uh blue these
6:13
might may well be saturating the camera
6:16
so they might look a bit weird so that's
6:17
the 430
6:18
blue the 575
6:24
yellow uh
6:26
475 light blue
6:29
the uh 520
6:31
green and the uh 630 red now one
6:36
interesting thing I noticed for the
6:39
575 it's actually it's actually using a
6:42
white lead and then filtering it rather
6:44
than using all the other ones are using
6:46
leads which are the fundamental colors
6:47
but uh this is actually doing white and
6:50
it's a combination of this filter and
6:52
the dichroic mirrors that are turning to
6:55
Yellow if we take the filter out and a
6:57
lot of the a lot of the um blue content
7:00
is going this way the red is going
7:02
straight through these two mirrors so
7:05
this is clearly not reflecting much of
7:08
that so we end up with the yellow coming
7:10
out of uh out of there which is a fairly
7:14
light yellow color which you don't
7:16
really see from high intensity leads so
7:19
that's clearly why they've used the
7:20
white to uh do this power consumption of
7:23
the white is pretty high so going up to
7:25
about 2 and 1 half amps on that color
7:27
whereas most of the other colors are
7:28
only drawing half an amp or so at 24
7:30
volts the uh the green is up to about
7:32
1.2 but say this thing is uh much
7:35
brighter and if you actually run all the
7:38
colors at the same time you get a fairly
7:41
reasonable um looking white coming out
7:43
of it and one thing you might just be
7:45
out to notice is there is some sort
7:46
color banding around here that's not
7:49
getting uh everything s completely
7:51
concentric and I think that's where this
7:53
fiber optic thing comes
7:58
in I'll
8:00
get a couple of Fairly accurately shaped
8:04
very sort of uniform color and looking
8:06
at What's um inside here we've basically
8:09
just got this Square Rod so this is
8:12
clearly yeah the lights just bouncing
8:13
off all the all the various sides to um
8:16
get a nice uniform illumination uh this
8:19
back bit looks like it's all potted so
8:21
nothing I really do to get in there I
8:24
think this is fiber so I have come
8:26
across um cables like this which are
8:27
liquid fill but just looking through the
8:30
end of this it's probably a bit hard to
8:31
see it does look like there fiber ends
8:34
going going on there and so there's this
8:36
feedback thing which is just obviously
8:39
compensating for the any light losses
8:41
through here to get an accurate
8:43
representation of uh the light that's
8:45
been launched out of these two
8:47
fibers and you see uh
8:49
these have got this sort of trapezium
8:54
shape light guides again it's like a
8:56
sort of acrylic or glass light guide
9:00
guess projected just to make the right
9:03
rectangular
9:04
shape and look at this Center assembly
9:07
um the light output doesn't uh change
9:10
whether you feed this in or not so it's
9:11
clear not doing any internal Clos Loop
9:14
control obviously there may well be some
9:16
facility for it to do that but it's not
9:17
being used in this
9:19
application and so this output just
9:21
produces a voltage on the uh outle
9:24
connector proportional to the amount of
9:26
light that's present so there's a little
9:28
diffuser in the back there
9:30
and then there's just some kind of uh
9:33
Optical sensor looks like a
9:35
chip looking at the lead it's a very
9:37
small package on the PCB with this lens
9:40
assembly over the top and these look
9:43
like they're actually on a copper
9:44
Metalized PCB for maximum thermal
9:47
performance and yeah it's a very small
9:49
package looks like it's a ceramic
9:51
package and there's a thermister there
9:53
for temperature monitoring this is the
9:56
475 blue one this is the 520 need to
9:59
Green which is uh rather different OB
10:02
it's a much bigger D with lots of bond
10:04
wise but also this looks like it's using
10:05
a phosphor if I shine a blue light at it
10:08
lights up green so this is actually a
10:10
phosphor conversion green lead which
10:12
I've I've come across before they want
10:15
that specific wavelength so they may be
10:17
easier to tune a phosphor than tune the
10:20
um semiconductor material to get the uh
10:23
right right wavelength from the lead
10:24
directly uh red 630 similar size to the
10:28
blue one or does seem to have a uh a
10:31
lens on top of it there is a sort of red
10:33
coloring to
10:35
the die but that doesn't appear to be
10:38
fluorescent as far as I can
10:39
tell and the white one again a little
10:41
bit different sort of much higher
10:43
current
10:46
connectors a makeer name on that
10:48
connector flot light not sure if that's
10:52
the connector or the lead
10:54
itself and obviously with the phosphor
10:56
and I'd imagine that phosphor may well
10:58
be tuned to get the maximum to the uh 5
11:01
cenm and actually this white one looks
11:04
like a St fairly standard product I just
11:06
found it in Mouse made by luminous
11:09
devices in fact actually I think all
11:11
these are based on various luminous
11:13
devices modules and they're you take
11:17
looks like they taking the nearest
11:18
wavelength and then just using these
11:19
filters to clean it up to get a precise
11:22
uh spectral line out of it so quite a
11:25
nice neat and um extreme
11:30
bright light source uh sure I've got any
11:33
particular use for it so I think this
11:35
might end up on
11:36
eBay but uh very pretty to look out and
11:40
without the uh risk of burning your eyes
11:43
out like you do with lasers so I thought
11:45
it would be interesting to try and
11:46
figure out the runtime of this things
11:48
like this we usually keep some sort
11:49
record of runtime cuz leads degrade over
11:51
time I couldn't get any software to work
11:52
through the USB face but then had a
11:54
thought probably going to be writing the
11:55
runtime periodically to the e s prom so
11:58
I just just scope up that and noticed it
12:00
was doing right every 5 minutes so I
12:02
just ran it for a while periodically
12:04
reading the E squ I just held the pick
12:05
in in reset and um put clip over to read
12:07
the square prom and found it was writing
12:10
one location per color every 5 minutes
12:12
so if one color was on it would write
12:14
that location every 5 minutes and just
12:16
increment it by one so after doing a few
12:18
tests with different colors of different
12:19
time periods it looked extremely
12:21
straightforward it's like a four bite
12:22
count for each color looking at the
12:24
original data that was in it all the
12:26
colors apart from Green were reading
12:28
zero and the green was reading four
12:30
indicating a total 20 minutes run time
12:32
ever if it was turned on run for a short
12:34
time then turned off that might not have
12:36
been counted but even so indicates this
12:37
thing wasn't used a great deal the whole
12:40
s process of doing a run can be several
12:42
hours but it'll only be doing probably
12:43
the Imaging at the end of that so you
12:46
wouldn't expect to be running for a long
12:47
time but say a single color for 20
12:50
minutes over its whole lifetime does
12:52
seem a little bit on the low side okay
12:55
let's look at the camera un fortunately
12:57
I managed to not record any sound when I
12:58
did this it's also a couple of months
13:00
ago so there's going to be a few details
13:02
that I've forgotten so I'm just going to
13:04
dub this over the original footage so um
13:07
take the lid off see this massive great
13:10
heat sink so this is a pel cool camera
13:12
we've got this blower fan producing a
13:14
fair amount of air flow through
13:16
it the connector here there's the ccds
13:19
mounted on the board on the
13:24
right this unplugs so we've got a bit of
13:27
power supply stuff on here
13:29
USB interface I think that's the Cyprus
13:32
microcontroller High speeded USB
13:34
interface there's a zyink spon fpga some
13:40
RAM and there's a couple of ATD
13:42
converters can't quite read what those
13:45
those are but anal
13:47
devices um little bit of bodgery around
13:51
here extra decoupling obviously they
13:53
have having some noise issues this is
13:55
around the ram chip quite a lot of extra
13:57
capacitors been added there
13:59
uh there's a couple of amplifiers prior
14:01
to the HD converter buffers or Andor
14:05
amplifiers taking the CCD
14:08
signal um bit more power spy stuff here
14:11
this is probably all to do with
14:12
generating the various CCD bias voltages
14:14
they uh need quite a lot of exotic
14:18
voltages next board down is just a
14:20
shield and an interconnect
14:24
boardly shielding the power supply stuff
14:26
from some the more sensitive an log
14:28
stuff
14:31
and this is the bottom board which is
14:32
just all power supply
14:34
stuff as you can see tons of capacitors
14:37
or Transformer in
14:42
there and this is the CCD which is a uh
14:47
very impressive thing this is a kf50 100
14:50
originally by true sense then codec
14:53
there ON
14:54
Semiconductor it's 50 megapixels uh the
14:58
only price I could find was this one
15:00
5,000 bucks and the architecture you can
15:03
see there actually two separate halves
15:04
which explains the Dual AZ converters
15:06
and two amplifiers it's literally split
15:08
down the middle and duplicated so it's
15:10
outputting two streams in parallel just
15:13
to keep the bandwidth sensible and it's
15:15
got this amazing um diffraction effects
15:18
it's got micro lenses over the pixel so
15:20
there's there's a bit more Optics going
15:22
on than on a normal
15:25
sensor few more bodges on the CCD board
15:28
including this wire which isn't really
15:29
tacked down very well which is a bit uh
15:32
bit of a mess quite a few bits around
15:34
this board where they've uh tacked
15:36
various bits on which is not super
15:38
impressive looks like CCD drivers on the
15:40
left with those 3 ohm um damping
15:43
resistors on the
15:47
output get a few more little bodges
15:50
around here some of
15:52
the and there's this separator the
15:54
silica gel to keep the moisture down but
15:56
there's this separator that actually
15:58
appears to be cut from piece of
15:59
antistatic
16:04
bag and this sort of thermal block on
16:06
top of this stack of three pel Cola
16:12
modules so as with any Stacks they get
16:16
um larger as they go back towards the
16:18
heat sink because each P's got to not
16:20
only take the heat from the previous but
16:21
also the waste heat which is quite
16:27
significant you see a little temperature
16:29
sensor here that copper block which
16:32
makes contact with the back of the
16:37
CCD and this's the back of the
16:40
pelas this then contacts the heat sink
16:44
on the uh rear there a few thermal pads
16:46
as well for some of the other power
16:47
components on this
16:51
PCB okay I've connected this uh camera
16:54
up I found some drivers on the disc that
16:56
seem to work under Windows 7 couldn't
16:58
get to install under Windows 11 though
17:01
um in the absence of any sort of lens or
17:03
being bothered to the proper amount I've
17:04
just put some f over it and put a little
17:06
pin in there to make a pinhole lens and
17:08
software gives a few options I'm not
17:11
entirely sure what all these are there's
17:12
obviously a clock frequency 22 MHz low
17:15
gain and with PFG no idea what that is
17:19
something something game programmable
17:20
Something game perhaps ver exposure
17:23
types I think focus is just like a
17:25
continuous grab until you tell it to
17:27
stop not entirely sure all these options
17:30
are obviously exposure time uh triggers
17:33
there ex external hardware trigger inut
17:35
you just trigger using a um thing on
17:37
screen so the resolution is 8176 by
17:40
6132 and you can actually bin those
17:42
where you combine multiple pixels to get
17:46
increased gain at the expense of lower
17:48
resolution down this is a 10sec exposure
17:51
obviously of the pin hole it's very uh
17:53
intensitive so we just stand still now
17:56
downloading it there's the uh exposure
17:59
so when it's
18:01
um there's a little status thing down
18:03
here so that tells you the um exposure
18:07
[Applause]
18:09
time it's this is just it
18:15
downloading um it is quite I'm seeing
18:18
quite a lot like smearing I think that I
18:20
don't know whether that's just due to
18:21
pixels overloading or something else I
18:24
mean yeah it's not it's not um out of
18:26
the question that there's something not
18:27
totally right about this camera
18:28
certainly was bodge wise on there um I
18:31
don't I'd imagine a camera like this
18:32
it's got a fairly narrow range of
18:34
intensities that it's happy with I'm not
18:36
going to spend a great deal of time on
18:38
this if you're interested in this camera
18:40
maybe for astronomy or something and
18:42
happy to sort of take the risk of it may
18:44
not be uh perfect I'll um I think I'll
18:47
stick this on eBay along with the
18:48
Illuminator I'll put a link down in the
18:50
description to the listing take your
18:52
chances to grab a bargain so for example
18:54
here we see this vertical streaking so
18:56
I'm not sure how normal that is this is
18:58
on fairly bright scene looking out the
19:02
window if I cut the exposure time down
19:04
on that it's now 1 second
19:07
exposure again most of the image
19:09
disappears again this is looks like it's
19:11
possibly over still overloading here go
19:14
that go down to say say quarter a
19:16
second so again I think there might be
19:19
some Auto gain control going on here um
19:21
this is with the PFG option let's try
19:23
turning that off and see what
19:25
happens so I'm not sure this is actually
19:27
more streaking or which just it's
19:29
cranked up the gain all the dis display
19:31
gray scale to show what um you know the
19:33
range of things that it's captured
19:36
there's one of one of 12 things in the
19:38
software there's um you can see of you
19:40
can't seem to read out the temperature
19:42
of the pelta cooler but you can set the
19:44
temperature and if you said it's a
19:46
different temperature you see the power
19:48
consumption jump up running the cooler
19:50
to get the temperature you requested but
19:52
I can't see anything anywhere that tells
19:54
you whether the cool is at the at the
19:56
temperature other than the power
19:57
consumption going down and there's no
19:59
temperature read out
20:03
here and just some yeah this is just
20:05
sort of very basic software I'm sure
20:07
there's like an API for more
20:09
sophisticated
20:10
applications but so if you know anything
20:12
more about these cameras please um stick
20:14
in the
20:15
comments um incidentally when I was
20:18
editing I didn't notice there was a bent
20:19
pin on the um CCD but I did fix that
20:22
before doing these tests and also
20:24
reactivated the um silica gel desicant
20:26
cuz I noticed it was uh I was getting
20:28
bit of condensation on the window but um
20:31
yeah so a couple of uh interesting but
20:34
maybe not particularly uh useful pieces
20:37
of Kit except for someone that's got a
20:38
very specific use so um I'll stick a
20:42
I'll stick these on eBay put a link in
20:44
the description and say hopefully
20:45
someone could actually make some uh good
20:47
use of these things
Example Output:
**Abstract:**
This video presents Part 2 of a teardown focusing on the optical components of a Fluidigm Polaris biotechnology instrument, specifically the multi-wavelength illuminator and the high-resolution CCD camera.
The Lumen Dynamics illuminator unit is examined in detail, revealing its construction using multiple high-power LEDs (430nm, 475nm, 520nm, 575nm, 630nm) combined via dichroic mirrors and filters. A square fiber optic rod is used to homogenize the light. A notable finding is the use of a phosphor-converted white LED filtered to achieve the 575nm output. The unit features simple TTL activation for each color, conduction cooling, and internal homogenization optics. Analysis of its EEPROM suggests extremely low operational runtime.
The camera module teardown showcases a 50 Megapixel ON Semiconductor KAF-50100 CCD sensor with micro-lenses, cooled by a multi-stage Peltier stack. The control electronics include an FPGA and a USB interface. Significant post-manufacturing modifications ("bodges") are observed on the camera's circuit boards. Basic functional testing using vendor software and a pinhole lens confirms image capture but reveals prominent vertical streaking artifacts, the cause of which remains uncertain (potential overload, readout artifact, or fault).
**Exploring the Fluidigm Polaris: A Detailed Look at its High-End Optics and Camera System**
* **0:00 High-End Optics:** The system utilizes heavy, high-quality lenses and mirrors for precise imaging, weighing around 4 kilos each.
* **0:49 Narrow Band Filters:** A filter wheel with five narrow band filters (488, 525, 570, 630, and 700 nm) ensures accurate fluorescence detection and rejection of excitation light.
* **2:01 Customizable Illumination:** The Lumen Dynamics light source offers five individually controllable LED wavelengths (430, 475, 520, 575, 630 nm) with varying power outputs. The 575nm yellow LED is uniquely achieved using a white LED with filtering.
* **3:45 TTL Control:** The light source is controlled via a simple TTL interface, enabling easy on/off switching for each LED color.
* **12:55 Sophisticated Camera:** The system includes a 50-megapixel Kodak KAI-50100 CCD camera with a Peltier cooling system for reduced noise.
* **14:54 High-Speed Data Transfer:** The camera features dual analog-to-digital converters to manage the high data throughput of the 50-megapixel sensor, which is effectively two 25-megapixel sensors operating in parallel.
* **18:11 Possible Issues:** The video creator noted some potential issues with the camera, including image smearing.
* **18:11 Limited Dynamic Range:** The camera's sensor has a limited dynamic range, making it potentially challenging to capture scenes with a wide range of brightness levels.
* **11:45 Low Runtime:** Internal data suggests the system has seen minimal usage, with only 20 minutes of recorded runtime for the green LED.
* **20:38 Availability on eBay:** Both the illuminator and camera are expected to be listed for sale on eBay.
Here is the real transcript. Please summarize it:
00:00:00 We have a fully
00:00:01 working Ubuntu environment
00:00:04 with an LTS release and a
00:00:05 good kernel on a $17 device
00:00:08 that has wifi that's got 40 GPIO pins
00:00:10 that draws nearly no power.
00:00:12 This thing is just phenomenal.
00:00:14 Welcome back everyone.
00:00:16 Today we are looking at the brand new
00:00:18 Luckfox Lyra Zero W.
00:00:21 This thing just came out
00:00:23 last month and I love it.
00:00:24 I think it's absolutely amazing.
00:00:26 So we're gonna dive into
00:00:27 all the details about this.
00:00:29 We're gonna benchmark it.
00:00:30 We're gonna flash it
00:00:30 with different images.
00:00:31 We're gonna plug it into some
00:00:33 screens and see how it works.
00:00:35 But first I just wanna let you know
00:00:36 that this video is sponsored by Brilliant
00:00:38 who can help you become a better thinker.
00:00:40 But more on them in a little bit.
00:00:41 Time to get into this.
00:00:44 So looking at this up close,
00:00:46 it is a very familiar zero
00:00:48 as they call it form factor.
00:00:50 So it's essentially,
00:00:52 I wouldn't say it's
00:00:53 competing with the Raspberry Pi Zero
00:00:54 but I think it's a
00:00:55 very, very good alternative
00:00:56 especially for how cheap it is.
00:00:58 So we've got a 40 pin
00:01:00 standard Pi Two style header there.
00:01:02 Now that's got I think 29
00:01:04 Rockchip Matrix I.O. pins on it.
00:01:07 So they can be multiplexed through
00:01:09 every different function.
00:01:10 That's because this has the RK3506B
00:01:13 which is a great little SOC.
00:01:15 The SOC has three cores
00:01:17 that are all ARM Cortex A7.
00:01:20 So 32 bit and it's the ARM
00:01:22 V7 instruction set or ARM HF.
00:01:24 It also has the
00:01:25 Cortex M0 in there as well.
00:01:28 But it's a very low power but very
00:01:30 powerful little SOC.
00:01:32 Next to that, we've then got 512 mega RAM
00:01:34 which is just insane.
00:01:35 We've got our wireless module there.
00:01:37 That's 2.4 GHz, SD card slot.
00:01:40 We've got USB pins there like
00:01:42 we've seen on the other Lyra.
00:01:44 We've got our power and USB on the go.
00:01:47 We've got a normal USB port
00:01:48 there, MIPI CSI for display,
00:01:52 an onboard antenna, an external antenna.
00:01:55 And then we have 256 meg
00:01:57 of SPI flash on the bottom.
00:02:00 So this is a very dense,
00:02:02 very powerful little device
00:02:04 and it's stupidly cheap.
00:02:05 It's 17 US dollars and I
00:02:08 have it in stock of course.
00:02:09 I also have four of these to give away.
00:02:11 So Luckfox was nice enough
00:02:13 that they decided to send me some extras.
00:02:15 They sent me five extras.
00:02:16 I'm keeping this one.
00:02:17 But four of them I'm gonna give away.
00:02:19 So hang around and
00:02:20 watch more of this video
00:02:22 to see how you can get
00:02:23 one of these for free
00:02:24 if you want one that is.
00:02:25 Going over to the Wiki.
00:02:28 You can see here that the documentation
00:02:30 is actually just a little bit lacking.
00:02:32 It's such a new product
00:02:33 that I haven't
00:02:34 finished filling this out yet.
00:02:35 If you jump up to the
00:02:36 product introduction here,
00:02:37 you can see the Lyra Ultra
00:02:39 and Ultra W do also use this.
00:02:41 So you get a little idea here.
00:02:43 It's got the 512 meg, it's got WiFi,
00:02:46 it's got the MIPI CSI interface there.
00:02:48 Sorry, MIPI DSI.
00:02:50 It's got your USB ports, 29 IO pins,
00:02:53 it doesn't have the
00:02:54 embedded controller though,
00:02:55 it doesn't have that 8 gig eMMC.
00:02:57 So I did do another
00:02:58 video previously on these
00:03:00 if you wanted to check it out,
00:03:01 but this is the Lyra Zero W.
00:03:04 So it's a little bit
00:03:05 thinned out as you would expect.
00:03:07 Getting started with
00:03:08 this is very easy now too.
00:03:11 It's got a initial image
00:03:13 flash onto the SPI flash
00:03:14 that we can boot up.
00:03:15 That has ADB.
00:03:17 So all we really have to do
00:03:17 is connect it using this port
00:03:19 to the power on our computer
00:03:20 and we'll be able to connect to it.
00:03:21 Let's have a look at how to do that.
00:03:23 For this, I'm just gonna
00:03:24 grab a standard black USB type C
00:03:27 cable, one end into the air, into there.
00:03:30 The other end, I'm gonna
00:03:31 plug it into my computer
00:03:32 over here and you'll
00:03:33 see very, very quickly
00:03:34 you've got this little heartbeat LED.
00:03:36 So that does not take long to start.
00:03:38 That's showing that it's
00:03:38 basically loaded the kernel already
00:03:41 and in a few seconds,
00:03:42 that's gonna be at a desktop environment.
00:03:44 Now, if we had configured WiFi,
00:03:45 we could SSH straight to it,
00:03:47 but we're gonna use the ADB
00:03:48 shell that's built straight in.
00:03:50 So jumping back over to the computer,
00:03:52 which is here, you can see,
00:03:55 we got ADB devices, it's listed there.
00:03:59 So if we got ADB
00:04:00 shell, we are straight in.
00:04:05 Have a look, we have Buildroot 2402.
00:04:08 So that's the one that comes, that's the
00:04:11 one that's in the SDK.
00:04:13 And what else do we have?
00:04:14 We have our 512 mega
00:04:15 RAM, no swap configured.
00:04:17 We have our 256 meg of SPI flash.
00:04:22 We have a 6.1 kernel, which is awesome.
00:04:25 You can see here, it's
00:04:26 that ARMv7 instruction set
00:04:28 and I can't type.
00:04:33 There we go.
00:04:34 So there are our three cores.
00:04:36 So this is a very,
00:04:37 very capable little device
00:04:39 for something that booted so quickly
00:04:41 and less than 12 seconds to be
00:04:45 completely ready essentially.
00:04:48 It's $17, boots out
00:04:49 quickly, that easy to connect
00:04:51 is actually quite amazing.
00:04:53 What I'm curious though is
00:04:53 how much power it consumes.
00:04:55 So we can test that out by
00:04:56 putting the FNB58 in the way.
00:04:59 Now this is just gonna be an initial,
00:05:02 what's it consume off
00:05:03 the bat sort of thing.
00:05:04 In fact, I'm gonna plug
00:05:06 it in over on this side.
00:05:07 It's not gonna be whilst it's running
00:05:09 anything too intense.
00:05:10 We will do that later.
00:05:12 I just wanna see to start
00:05:13 with what sort of power profile
00:05:14 we're looking at for
00:05:15 something that you can plug in,
00:05:16 use instantly and it's ready to go.
00:05:21 So there we go.
00:05:25 It's drawing stuff all.
00:05:30 It peaked at 370 milliamps there, which
00:05:32 you should have seen.
00:05:33 So it did manage to draw a bit whilst
00:05:35 it's doing something
00:05:36 but now it appears to have booted
00:05:38 and it's idling around 128.
00:05:40 If we jump back over to the
00:05:41 computer, it's kicked us out.
00:05:43 It hasn't picked it up yet.
00:05:45 Oh yeah, of course,
00:05:45 because it's not plugged in.
00:05:47 This power cable goes up
00:05:48 to my dedicated power supply
00:05:50 but that's stable at 130 milliamps now
00:05:53 running a Linux distribution,
00:05:54 which really is really incredible.
00:05:58 Now, if you are enjoying this content
00:05:59 and if you like
00:06:00 seeing this sort of thing,
00:06:01 please don't forget to like and subscribe
00:06:02 because the algorithm is
00:06:04 pretty harsh on YouTube
00:06:06 but every bit of
00:06:07 engagement, whether it's a thumbs up,
00:06:08 whether it's the
00:06:09 subscribing to the channel
00:06:10 or just leave me a comment
00:06:11 below, really, really helps.
00:06:14 Now, this, as I said,
00:06:16 is the initial image
00:06:17 that it comes with.
00:06:18 It's not necessarily the
00:06:18 latest one from the SDK.
00:06:20 So you can either
00:06:20 download it or build it yourself.
00:06:22 In this instance, I have built it myself
00:06:24 but if we have a look
00:06:25 at where to download it,
00:06:26 coming back over here, if
00:06:27 we go to image flashing,
00:06:29 you can see it does
00:06:30 support Ubuntu and Buildroot
00:06:32 but unfortunately the Ubuntu
00:06:33 images are no longer available
00:06:34 because they don't
00:06:35 have approvals anymore.
00:06:36 I'm not sure of the exact story
00:06:38 but you can click on
00:06:39 the Google Drive link
00:06:40 which I've actually already got here
00:06:42 and you can download
00:06:43 the Lyra Zero images.
00:06:45 Now, there's no point
00:06:45 putting that on an SD card
00:06:47 unless you want more storage
00:06:49 but you can always mount
00:06:50 that separately, I believe.
00:06:51 So downloading and
00:06:52 extracting that flash zip file,
00:06:55 you're left with a pile of files.
00:06:57 So if we have a look
00:06:58 at those extracted files
00:06:59 that I've got here, let's go
00:07:01 into here, you got a couple.
00:07:03 All the one that we're really gonna need
00:07:04 is that update.image.
00:07:07 So we have this upgrade tool
00:07:09 and you can use this or RK Dev tool.
00:07:12 The instructions are in here.
00:07:14 So image flashing, here we go.
00:07:16 You can see all the different platforms
00:07:18 and how to flash it.
00:07:20 Now I am using the update tool
00:07:23 which I have copies in here as well.
00:07:24 So on my GitHub repo, I do
00:07:26 put some of my own images up
00:07:27 and I will be putting
00:07:28 another one up for this
00:07:29 but in the Linux folder, you can see I've
00:07:31 got the upgrade tool
00:07:31 and the RK flash script
00:07:33 if you want it to save
00:07:34 downloading the whole SDK
00:07:35 because it does
00:07:36 actually unfortunately say
00:07:38 that it needs to
00:07:39 download the SDK to get it
00:07:41 but stuff that if we go upgrade tool LD,
00:07:44 we can't see it connected
00:07:45 because it is still over here.
00:07:47 I will grab this from there,
00:07:51 plug it back into the computer.
00:07:53 There we go.
00:07:55 What I forgot that we
00:07:56 need to do is hold down
00:07:57 the boot button whilst we connect it.
00:08:00 So that's gonna put it in the mode
00:08:01 where we can flash it with a new image.
00:08:03 And I usually just hold it
00:08:04 for two or three seconds.
00:08:05 Once that's done, we can
00:08:07 go back to the computer
00:08:08 and we'll see that device is there.
00:08:11 So if we do clear that,
00:08:14 we can do upgrade tool,
00:08:18 update firmware, and then we
00:08:20 can specify this update.image.
00:08:22 So now that's gonna push that image
00:08:23 straight onto the SPI flash
00:08:25 and it's gonna reboot
00:08:26 straight away afterwards.
00:08:27 When it does, it's gonna
00:08:28 have the latest image there
00:08:29 for us to use.
00:08:31 Now, of course, you can
00:08:32 also do an SD card image
00:08:34 with the, it needs the
00:08:35 windows tool to do that.
00:08:36 So I'm gonna put an SD
00:08:37 card image up for you
00:08:39 that is a raw grab that you
00:08:41 don't need to use SD Disk Tool
00:08:42 for, you can use Balena Etcher out
00:08:44 or just the discs utility in Linux.
00:08:47 If you are wanting to do that,
00:08:49 I'd recommend coming
00:08:50 and grabbing one of these.
00:08:51 I've just got these in stock
00:08:53 and started using them myself
00:08:55 because of how damn good they are.
00:08:57 There was a review here where this bloke
00:08:59 kind of broke down every SD card
00:09:01 and had a look at what they can do
00:09:02 and how reliable they are.
00:09:04 Go have a read of it if you want.
00:09:05 But these are extremely
00:09:06 cheap and extremely fast.
00:09:08 So I got those.
00:09:09 What you may also want,
00:09:11 depending on what your
00:09:12 wifi at home is like,
00:09:13 is an external antenna for this.
00:09:15 Now that's what I've been
00:09:16 using, but you don't have to.
00:09:18 Now to connect the antennas,
00:09:20 you do wanna be pretty careful.
00:09:22 I recommend doing it
00:09:22 because I have found this
00:09:23 onboard antenna isn't too great.
00:09:25 I'm not too sure what the reason is,
00:09:27 but I've got this one here
00:09:28 and you just wanna be a little bit gentle
00:09:30 when you connect this
00:09:31 little IPEX connector
00:09:32 because they can
00:09:33 easily break off the board
00:09:34 and you probably don't want
00:09:35 it powered on like I have here.
00:09:38 Now that's all flashed.
00:09:40 And if we come back over here,
00:09:42 we can see we've got
00:09:43 our little blinking light
00:09:45 on the computer as well.
00:09:46 If we again go ADB
00:09:47 shell, we are straight in.
00:09:49 Now I did say I had four of
00:09:51 these to give away for free
00:09:53 and thank you to
00:09:54 Luckfox for sending them.
00:09:55 To do so, all you need to do is buy one
00:09:58 with anything else from my shop
00:10:00 and throw in the discount code.
00:10:02 So having a look here,
00:10:03 I'm gonna grab one of
00:10:04 these SD cards as well
00:10:05 because you'll probably want one too
00:10:06 when you see what we've got
00:10:07 coming up and the antenna.
00:10:10 And then we'll go to the Lyra 0W,
00:10:12 which is easily available
00:10:13 on the homepage at the moment
00:10:15 and marked down
00:10:15 because it's new and awesome
00:10:17 and I want everyone to have them.
00:10:18 So once you've got the
00:10:19 accessories in your card
00:10:20 along with your Lyra
00:10:21 0W and you go checkout,
00:10:23 all you have to do here is put in this
00:10:26 Lyra 0W discount code
00:10:29 and you can see it 100% discounts that.
00:10:31 Then you just pay for the
00:10:32 accessories, plus shipping
00:10:34 and it'll arrive in
00:10:34 your post box, your PO box,
00:10:36 whatever you've got in a couple of weeks.
00:10:38 Probably if you're in
00:10:39 the US a week or two,
00:10:41 but I ship out of Australia, so it's
00:10:43 subject to where you are.
00:10:45 Now, as I said, this does
00:10:47 technically support Ubuntu,
00:10:48 but they have taken it out.
00:10:50 I happen to have an older
00:10:51 version of the SDK though,
00:10:52 that still had Ubuntu in it.
00:10:54 And so I have actually
00:10:56 created an SD card image
00:10:59 with Ubuntu for this,
00:11:00 which was a little bit of work,
00:11:02 but I think is absolutely worth it.
00:11:04 Alrighty, so over here on the computer,
00:11:06 if we just go ADB shell,
00:11:08 the same as we did before,
00:11:09 we're straight back in.
00:11:10 And if we have a look at
00:11:11 the release information,
00:11:12 we can see we now have
00:11:13 this 22.04.5 environment,
00:11:16 which is a little bit more capable.
00:11:18 We still have that
00:11:19 same 6.1.99 kernel too,
00:11:22 and you'll see that we do have the same
00:11:24 resource consumption
00:11:25 and that is a tiny, tiny
00:11:27 amount of RAM to be used.
00:11:29 Now, a lot of people of course,
00:11:30 do want to join the
00:11:31 wifi and use it that way.
00:11:33 As I said, the external
00:11:34 antenna really helps,
00:11:35 but you do need to configure it too.
00:11:37 So the first thing is
00:11:38 configuring the network details
00:11:42 in this configuration file.
00:11:43 I'm using my nice secure PiFi.
00:11:46 And just so you know,
00:11:46 all of this is
00:11:47 actually in the documentation.
00:11:49 If you go to the Lyra,
00:11:51 you'll see there's a wifi
00:11:51 and Bluetooth page here.
00:11:52 For some reason I've got the Chinese one,
00:11:54 but it shows you what to do.
00:11:56 So me showing you,
00:11:57 we've modified that file.
00:12:00 We're gonna do kill all
00:12:01 minus nine wpa_supplicant,
00:12:04 just to terminate
00:12:05 that background process.
00:12:06 And then we're gonna run it again.
00:12:07 So wpa_supplicant minus
00:12:10 capital B for background,
00:12:11 minus I to specify the WLAN0 interface,
00:12:14 minus C to then give it that config file.
00:12:18 That takes a quick second
00:12:19 and we'll see that we
00:12:20 have this interface up now,
00:12:22 but it doesn't have an address.
00:12:23 So you do also need
00:12:24 to do dhclient WLAN0.
00:12:27 Now, if you're still in
00:12:28 the Buildroot environment,
00:12:30 the command you wanna use
00:12:32 is udhcpc minus IWLAN0.
00:12:35 Back here though, we
00:12:36 can see that is connected
00:12:39 and we have internet.
00:12:41 That is all you really need
00:12:43 because then you can start
00:12:43 using apps to install things.
00:12:46 One thing you might
00:12:46 have issues with though,
00:12:47 is of course systemd and resolved.
00:12:50 So always just go to name server 1.1.1.1
00:12:54 and make sure that works with a quick
00:12:55 little ping of Google
00:12:56 or something like that.
00:12:57 So we have a fully
00:12:59 working Ubuntu environment
00:13:02 with an LTS release and a
00:13:04 good kernel on a $17 device
00:13:06 that has wifi that's got 40 GPIO pins
00:13:09 that draws nearly no power.
00:13:10 This thing is just
00:13:12 phenomenal, but it still does more.
00:13:14 And that's what I'm
00:13:15 gonna have a look at now
00:13:16 and show you the last
00:13:17 awesome part of this.
00:13:19 Before I do that last bit actually,
00:13:20 I'm gonna put a little heat sink on here
00:13:22 and I think we can give
00:13:23 it a bit of a benchmark
00:13:24 and see what it's doing.
00:13:25 Again, you shouldn't
00:13:26 put that heat sink on
00:13:28 whilst it's running, but I'm done.
00:13:29 What are you gonna do?
00:13:31 Back over on the computer,
00:13:33 if we have a look over here,
00:13:34 I can go apt install
00:13:36 python3 numpy and python3 psutil.
00:13:40 We're gonna need these for
00:13:41 a little benchmark script
00:13:42 that I've written.
00:13:44 Back in my GitHub repo,
00:13:45 if we have a look here,
00:13:47 I've got one called ML
00:13:49 accelerator benchmarks.
00:13:50 I started putting these
00:13:51 together a few months ago
00:13:52 and I haven't been keeping it up to date,
00:13:54 but it is actually pretty cool.
00:13:56 The idea is to be able
00:13:57 to benchmark small devices
00:13:58 where Geekbench might not run.
00:14:00 And I'm starting to
00:14:01 store some results in here.
00:14:02 You can see I actually ran
00:14:04 this already a few days ago,
00:14:06 but I'm gonna show you
00:14:07 how to run it now as well.
00:14:08 To make it easy, I'm just
00:14:09 gonna grab the one python file.
00:14:12 We can see here,
00:14:13 we're gonna need that one
00:14:15 and we're gonna need that one.
00:14:16 I think most of the others
00:14:18 should already be on here,
00:14:19 but we will find out very shortly.
00:14:21 So let's install those.
00:14:24 Once they're installed,
00:14:25 I'll download that python file
00:14:27 and we will get Geekbench going too.
00:14:29 If you have a look at Geekbench preview,
00:14:33 I'll just type that in.
00:14:35 Version five supports 32 bit.
00:14:37 Version six requires ARM arch 64,
00:14:40 but this has the ARMHF
00:14:41 or the ARMv7 version.
00:14:44 So we'll test that out too.
00:14:47 There we go.
00:14:48 And now let's see if we're
00:14:50 missing any extra dependencies.
00:14:52 I'm hoping that's it though.
00:14:53 No, look at that, look at it go.
00:14:55 All right, it just took a leap.
00:14:56 I didn't actually
00:14:57 expect it to get this far.
00:14:58 It got up to 2048 by 2048
00:15:00 and it says it can go higher.
00:15:02 So it leaves a little bit
00:15:03 of a safety factor there,
00:15:04 gives you a bit of
00:15:05 background information.
00:15:06 It will do some warmup runs
00:15:07 and then it's gonna
00:15:07 start absolutely hammering
00:15:09 the matrix multiplication
00:15:10 to see what the performance is like.
00:15:12 I will let this finish
00:15:13 and then we'll come back
00:15:14 and we'll have a look
00:15:15 at the results of this.
00:15:18 Now, this isn't something
00:15:19 I learned in school though.
00:15:21 Unfortunately, I had to teach myself
00:15:23 and that's why I'm thankful
00:15:24 for today's sponsor, Brilliant.
00:15:26 If you wanna start
00:15:27 learning to program in Python,
00:15:28 which is consistently ranked
00:15:29 as one of the most
00:15:30 popular programming languages
00:15:31 and has gained widespread
00:15:32 use in machine learning and AI,
00:15:34 then Brilliant's programming with Python
00:15:36 is the place to start
00:15:37 and gives you hands-on
00:15:38 experience with real programs
00:15:39 and helps you to learn to
00:15:40 think like a programmer.
00:15:42 I started using Brilliant
00:15:43 before they even offered this sponsorship
00:15:45 when I wanted to sharpen
00:15:45 my circuit design skills.
00:15:47 And now my partner's using it too,
00:15:48 although she's
00:15:48 started with visual algebra.
00:15:51 Brilliant helps you build
00:15:51 your critical thinking skills
00:15:53 through problem solving,
00:15:54 not through memorizing.
00:15:55 So whilst you're building real
00:15:57 knowledge on specific topics,
00:15:58 you're also becoming a better thinker.
00:16:00 Whether on the computer or mobile,
00:16:01 diving into a new course
00:16:02 like programming in Python
00:16:04 or doing a quick practice
00:16:04 session of some algebra,
00:16:06 Brilliant is the go-to platform
00:16:07 to help you reach your learning goals.

00:16:24 Brilliant, learn by doing.
00:16:27 Coming back to these results,
00:16:28 what we can see here is
00:16:29 the theoretical power,
00:16:31 the final number that we wanna look at
00:16:32 that we can compare to other things.
00:16:34 There are some more details here
00:16:35 if you really wanna dive into it,
00:16:38 but this one, which
00:16:39 probably needs some commas in it,
00:16:40 is the important one.
00:16:41 So that's 169 million.
00:16:43 Doesn't sound like much,
00:16:44 but if we compare that to
00:16:46 the ESP32-P4 or an RP2350,
00:16:49 we start to see some patterns here.
00:16:51 So this one is at one million
00:16:54 and that's the ESP32-P4,
00:16:56 1.8 million I should say.
00:16:58 The MicroPython RP2350
00:17:02 was an amazing 8.3 million.
00:17:04 And as you'd expect, we'd
00:17:06 got just under one million
00:17:08 in the results for the RP2040.
00:17:10 And I included a quick breakdown of the
00:17:11 math in this one too.
00:17:13 So it is a very, very powerful device.
00:17:17 And now we can get into the last thing
00:17:19 that I wanna do with this.
00:17:20 And this is the cool bit.
00:17:21 I wanna put a display on it.
00:17:24 This is the WaveShare
00:17:25 10.1 inch DSI display.
00:17:27 I've got these in stock.
00:17:29 I think they're about
00:17:30 80 Australians, so 50 US,
00:17:31 but they are a great display.
00:17:33 They're compatible
00:17:34 with this out of the box.
00:17:35 And so we can plug it
00:17:36 in and see what happens.
00:17:37 Let me just sort that out quickly.
00:17:39 All right, that is all plugged in.
00:17:41 I'm also gonna plug in my USB receiver
00:17:45 for the keyboard and mouse.
00:17:47 Grab these over here
00:17:48 and plug the power in.
00:17:54 Now there isn't edge case
00:17:55 to do with the power timings
00:17:57 for this and you can see
00:17:58 I've hijacked the power
00:17:59 straight from the board
00:18:00 there, but nothing's happened.
00:18:01 So I'm just gonna hit reset
00:18:03 because sometimes the
00:18:04 display hasn't initialized
00:18:06 before it tries to
00:18:06 output from what I can figure.
00:18:08 We can see though, the
00:18:09 display is instantly working,
00:18:10 which is awesome.
00:18:11 This is burning Ubuntu now
00:18:12 because we still have that SD card in,
00:18:14 but even if we didn't,
00:18:15 it does the same thing
00:18:16 with the Buildroot environment as well.
00:18:20 There we go.
00:18:20 It's given us a little
00:18:21 warning about the wifi
00:18:22 and we are there.
00:18:23 So we can just go route and route
00:18:27 and we have our
00:18:28 environment much like we had before
00:18:30 when I got Doom running on this as well.
00:18:31 If you're curious,
00:18:32 check out the recent video
00:18:34 about the other Lyras, the
00:18:35 Lyra Ultra that I tried out.
00:18:38 All righty, over on the computer,
00:18:40 we have our internet working now.
00:18:42 And what's really cool
00:18:43 is this gives us an option
00:18:44 that you may not consider.
00:18:45 And that's what we can just do,
00:18:46 apt install xubuntu-desktop.
00:18:50 So that's a meta package that's got XFCE,
00:18:53 Lite DM and everything like that
00:18:55 to get going with the
00:18:55 Graphical Interface.
00:18:56 Now this is a frame buffer interface.
00:18:58 It doesn't have a GPU backing it,
00:19:01 which means it is software driven
00:19:02 and it is gonna be slow,
00:19:04 but it does give you a lot of options.
00:19:06 Now you don't have to use,
00:19:07 hit yes to start that going.
00:19:09 You don't have to use that.
00:19:11 If you have a look at
00:19:12 the documentation here,
00:19:13 they do actually have a
00:19:14 bit about the Qt environment.
00:19:16 And that's because Qt can output
00:19:18 to the frame buffer interface.
00:19:19 So any apps that you
00:19:21 can get web browsers,
00:19:22 there's forks of web browsers,
00:19:24 fork of Chromium I think,
00:19:25 that outputs straight to the frame buffer
00:19:26 and that's how I did it with Doom.
00:19:28 That though is
00:19:29 downloading and installing.
00:19:31 To skip the wait,
00:19:31 I've got one I've
00:19:32 already prepared earlier.
00:19:33 So back over here,
00:19:35 let's just pull that
00:19:36 power straight out of there.
00:19:37 We'll pop that SD card
00:19:38 straight out of there.
00:19:40 And we'll put my other one in
00:19:41 that I already
00:19:42 downloaded these files onto
00:19:43 and see something absolutely awesome.
00:19:48 Boot back up or not,
00:19:51 hit the reboot button.
00:19:53 Now we have our display.
00:19:57 There we go.
00:19:58 That is our XFCE login prompt.
00:20:00 So we have a $17 device
00:20:03 with triple core 512 mega RAM,
00:20:05 SPI flash and SD card slot,
00:20:08 three USB ports,
00:20:09 40 pin pie to header
00:20:10 that can power a 1280 by 800 DSI display.
00:20:14 That is just amazing.
00:20:16 Now this is also a touch display,
00:20:18 as you can see.
00:20:19 So if we put our password in here,
00:20:21 we can log in with touch.
00:20:23 As I said, it's still software driven.
00:20:25 So this is gonna be a laggy interface,
00:20:27 but it gives you a lot of options.
00:20:28 There is a lot of cool stuff
00:20:30 that you can do with something so cheap,
00:20:31 so powerful and so capable.
00:20:34 I love this thing.
00:20:35 I'm giving four of them away for free.
00:20:37 If you want one, go and grab it.
00:20:39 What I'm gonna do after this
00:20:40 is put the other SD card back in,
00:20:43 download Geekbench and we'll
00:20:44 benchmark it there as well.
00:20:45 So we have some
00:20:46 comprehensive benchmark results
00:20:47 of what this is actually capable of
00:20:49 without anything
00:20:49 running in the background.
00:20:50 And I'll leave this heatsink on
00:20:52 because it is doing it
00:20:53 a little bit of a favor.
