This video from Open Research Institute Inc. reports on their successful participation in the annual DEFCON hacker conference in Las Vegas and a recent RockSat-X launch. At DEFCON, the team showcased a suite of open-source digital radio projects, including the Locutus modem, Locus conference server, Interlocutor human-radio interface (emphasizing accessibility), RFBitBanger kit, regulatory work, Ribbit Radio, and open-source synthetic aperture radar (SAR) using GNU Radio and Pluto SDR. They staffed two tables for 20 hours over three days, receiving overwhelmingly positive feedback, particularly for the accessibility features of Interlocutor. Concurrently, they announced a successful RockSat-X launch collaboration with the University of Puerto Rico, featuring an older version of their Opulent Voice system transmitting from space. The report highlights the community's enthusiasm for hands-on radio projects and the growing demand for interdisciplinary skills in FPGA design, digital signal processing, and hardware.
Summarizing the Transcript: DEFCON and RockSat-X Highlights
0:00 - DEFCON Participation: The Open Research Institute (ORI) successfully exhibited their open-source digital radio projects at DEFCON, a major hacker conference in Las Vegas, specifically within the RF (Radio Frequency) Village.
Locutus Modem: A live demonstration of their minimum shift keying (MSK) modem, visualized on a spectrum analyzer, attracting significant attention.
Locus Conference Server: Its first public live demonstration.
Interlocutor: A human-radio interface demo, highlighting accessibility with multi-station setup, headphones, microphone, and keyboard, allowing direct user interaction. It's Python-based and runs on various platforms including Raspberry Pi, Macintosh, and Windows (in progress). ORI is committed to making it accessible for users with visual, auditory, mobility, or cognitive challenges, and plans to integrate the "Atkinson's hyperlegible font" for enhanced readability.
RF Bitbanger Kit: A floor model was displayed, with links to ORI's eBay store for purchasing the kit.
Ribbit: Presented as a poster session (volunteer absent), but was recognized and used by many attendees.
Open-Source Synthetic Aperture Radar (SAR): A radar demo using cantennas, GNU Radio, and a Pluto SDR, based on an MIT courseware class adapted to modern SDRs.
3:45 - Event Logistics & Engagement: ORI staffed two tables for 20 hours over three days with a crew of four volunteers. They were filmed for Defcon TV and interviewed by staff, also engaging with the Policy Village on regulatory work.
4:46 - Accessibility Focus: A key takeaway was the strong appreciation for ORI's commitment to making their radio projects, especially Interlocutor, as accessible as possible.
12:02 - Audience Interaction: The team engaged with a diverse audience, from radio novices to highly knowledgeable experts, guiding them based on their hardware or software backgrounds. They also encouraged individuals taking the ham radio license test (Defcon holds the record for the largest amateur radio exam session in the US).
13:40 - Learning Curve Insights: They noted that many struggle with concepts like complex baseband and IQ modulation in software-defined radio, which are crucial for advancing in the field.
14:50 - Industry Demand: Observations at the booth indicated a high demand for professionals skilled in FPGA design, digital signal processing, and hardware, highlighting a rare combination of expertise.
7:59 - RockSat-X Launch: ORI reported a recent successful RockSat-X launch in collaboration with the University of Puerto Rico, where an older FSK version of their "Opulent Voice" system successfully transmitted from space.
8:56 - Positive Outcomes: Both events were described as invigorating, with overwhelming positive responses from enthusiastic attendees who appreciated the hands-on demos and open-source approach.
