MNT Reform: A Journey in Open Hardware Laptops
0:15 Introduction: Lukas "minute" Hartmann, founder of MNT Research, discusses the challenges and learnings from building open hardware computers over the past seven years.
1:08 Talk Structure Change: Originally planned as a systematic walkthrough, the talk pivoted to a historical overview with lessons learned, aiming to be more engaging.
2:21 Origins of Reform: Frustration with Apple's planned obsolescence and lack of hardware documentation led to the Reform project's start in 2017. The goal was to create a transparent, customizable, and open-source laptop.
5:04 Collaboration is Key: Teaming up with industrial designer Anna Dantas was crucial. The advice is to find skilled, determined collaborators.
5:32 Iteration over Perfection: Prioritizing getting things done and iteratively improving proved more effective than aiming for perfection from the start.
6:14 Design Process: The initial design involved selecting an open and documented processor and development board, then hand-wiring components.
7:22 Custom Motherboard: A custom PCB was developed in KiCad. The use of a System on Module (SoM) simplified the design process, avoiding direct dealings with processor manufacturers.
8:22 SoM Trade-offs: SoMs are not typically open hardware but are treated as standard, readily available parts, allowing the rest of the system to remain open.
8:41 Early Prototypes: Early versions were largely 3D printed and laser-cut, including keycaps, and were described as a "huge and glorious mess".
8:58 Initial Demand: An early offering of ~10 hand-assembled units at β¬600 each sold out quickly, validating demand.
9:33 Manufacturing Challenges: 3D printing proved too slow and imprecise. Experiments with vacuum casting were unsuccessful. CNC milling of aluminum (outsourced to China) became the solution for the case.
10:24 Keycap Solution: DIY keycaps were inadequate. A partnership with a specialized keycap molding company resulted in injection-molded, laser-engraved keycaps.
10:58 Additive Manufacturing Limitations: Additive manufacturing couldn't achieve the required quality for crucial touch-related parts, leading to a reliance on traditional manufacturing methods.
11:33 Reform 2 Redesign: Issues with the original Reform led to a complete redesign and processor upgrade to the IMX8M.
11:51 Binary Blob Dilemma: The switch to the IMX8M introduced a binary blob for the memory controller, a compromise for 64-bit performance.
12:29 Crowdfunding: A Crowd Supply campaign enabled larger-scale production of the Reform 2.
12:43 Reform 2 Features: Radical elements included eight user-exchangeable 18650 battery cells (lithium iron phosphate) wired in series (up to 30V).
13:00 External Help: External help was crucial (Timon Scch, Ellen and Zoe of Fully Automated, F Schneider from fixme, Yosh).
13:47 "The Cursed Module": An attempt to create a fully open-source module with the NXP LS1028A processor (no binary blob for memory training) faced numerous challenges (processor shortages, boot issues). Only around 50 units were shipped.
16:11 Risk Assessment: Such ambitious designs are risky on a shoestring budget but possible with high pain tolerance.
16:29 FPGA-Based Module (RKX7): Another purity-focused project, creating an FPGA-based module with an open-source SoC at the gate level.
17:12 Resource Drain: These "purity projects" consumed significant time and energy with limited user benefit, hindering the company's sustainability.
17:25 Pick Your Battles: Philosophical purity is appreciated by few; most users are pragmatic and accept small trade-offs for usability.
17:59 Pragmatism and Incremental improvement are a good thing
18:27 Performance Issues: The initial processors struggled with demanding web applications, necessitating an upgrade.
18:58 RCM4 Module (Raspberry Pi Adapter): Initially a "joke," the RCM4 adapter allowed using a Raspberry Pi CM4 as the processor. A more popular, faster alternative was the Banana Pi with an Amlogic A311D processor.
19:31 BayLibre and Mainline Linux: BayLibre's work on mainlining Amlogic processor support and panfrost open-source GPU drivers was critical.
20:01 "David Lynch Way" of Development. Follow intuition/subconcious, even if it seems irrational.
20:13 Pocket Reform: A smaller, 7-inch device aimed at smartphone replacement for some use cases (writing, basic telephony). It used an NXP IMX8M Plus processor.
21:31 Production Obstacles: The chosen display (from the Nexus 7 v2 tablet) was end-of-life, with existing stock having quality issues. A replacement solution was found but caused delays and required modifications.
23:09 Pocket Reform Success: Despite challenges, Pocket Reform was more successful than anticipated.
23:33 Rockchip RK3588: The adoption of the Rockchip RK3588 SoC provided a significant performance boost, with Collabora contributing to mainlining drivers.
24:30 Altium to KiCad: Firefly's Altium schematics and footprints were converted to KiCad using KiCad's import feature.
25:01 Reform Next: A redesign of the 13-inch laptop aiming for a thinner profile (25mm vs. 45mm) while retaining the eight batteries and mechanical keyboard.
25:51 Design Changes: Sacrificed the acrylic bottom plate and trackball, splitting the motherboard into smaller PCBs. The processor is cooled by direct contact with the aluminum body.
26:11 Novena Inspiration: Includes a 40mm spaced mounting grid for user-added electronics, inspired by the Novena laptop.
26:25 Separated Ports: Ports are on separate PCBs, allowing for custom designs.
26:48 Crowdfunding Campaign: A crowdfunding campaign for Reform Next was launched.
27:02 Cloning and Modification: Users have successfully cloned and modified Reform designs, demonstrating the openness of the project.
27:52 Cost of new generation. Around 2000 dollars.
29:37 Module Choice Philosophy. They offer a range of modules and allow customers to prioritize between openness, speed, and specific features.
35:31 Easier OS Compatibility Support for edk2/UEFI will improve compatibility with different OS's.
38:12 CE Compliance Can be a significant cost, with chinese companies being cheaper.
