Hosts Dave Jones and Chris Gamble discuss the open-source RC controller from Gizmo For You, highlighting its complex injection-molded cases and 8-layer PCB. They review Ken Lumbard's 'Reading Jim Williams' project, which curates and analyzes the application notes of legendary analog engineer Jim Williams. The hosts also cover rumors of a DARPA humanoid robot grand challenge and share experiences using CircuitLab for SPICE simulation.
Hosts Chris Gammell and Dave Jones discuss the recent Antares rocket explosion, the Hackaday Prize space trip controversy, and the passing of Tom Maglioli from Car Talk. They also cover U-beam's wireless charging technology, Dr. Greg Shaver's ultrasound chip startup, and DIY projects including a Tony Stark Halloween costume and reflow oven modifications.
Security researcher Mike Grover (MG) explains how he creates cable implants by milling tiny PCBs with an OXO mill to fit inside USB cables. He details the process of designing minimal HID attack circuits using ATtiny microcontrollers and the challenges of home-reflowing BGA components on ultra-thin FR-4 boards. Grover discusses the shift from wired to wireless implants and the importance of rapid iteration in hardware security research.
Hosts Jen Castillo and Alvaro Prieto discuss their pandemic-era projects, including Alvaro's recreation of his father's 7400-series digital clock, a USB-C power adapter using a Cypress chip, and a t-shirt quilt. Jen details her reverse engineering of a greeting card chip, her exploration of Chinese manufacturing via Alibaba, and her choreography of a remote dance piece. They also cover the cancellation of hardware conferences like Hackaday Supercon and HackRF, and recommend movies such as 'Mood Indigo' and '3 Idiots'.
Jeri Ellsworth, founder of Tilt Five, discusses her journey from reverse engineering Commodore 64 chips for the DTV toy to launching an augmented reality tabletop gaming platform. She details the technical challenges of emulating legacy silicon quirks, the manufacturing failures in China, and her strategy of using viral marketing to drive early sales. Ellsworth also shares insights on her current startup's upcoming Kickstarter, the importance of genuine brand personality, and her favorite tools for hardware debugging and assembly.
