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.
Carl Bugeja, an engineer from Malta and creator of flexar.io, discusses his work creating actuators from flexible PCBs to flap origami figures and drive a foldable rover. He details the design of self-soldering circuits using resistive squiggles and PCB motors with printed windings, explaining how he overcame thermal limitations and component shortages. Bugeja also shares insights into his open-source hardware philosophy, his YouTube documentation process, and the business model behind selling development kits.
Carl Bugeja, founder of microbots.io, discusses his transition from electronics engineering and YouTube experimentation to commercializing PCB motors and actuators. He details the engineering challenges of designing flexible PCB coils, managing manufacturing tolerances, and selecting drivers for tiny robotics. Bugeja explains how his company is scaling production and developing new products like the 'Time Flap' display and a foldable rover robot.
The host of The Electromaker Show covers several maker projects and tech news, including a perpetual solar-powered watch by Suhi Trush and an Arduino-based meme machine using old keycap lamps by Alex Kout. The episode highlights the ESP32 C6 Bug on Crowd Supply, the Tinko HUSH EL light engine, and the overclocking of the Raspberry Pi 5 by Jeff Geerlings. It also discusses open-source efforts to reverse-engineer the Rockchip NPU and provides details on the upcoming Arduino Days 2024.
Ian from Electromaker announces the winners of the Eurocircuits PCB Design Contest, including Alistair’s Trundlebot for first place and Daniel Mantioni’s retro computing cartridge for sustainability. He then recaps Maker Faire Rome 2022, highlighting projects like Brillo the Bartending Robot, Airquno air sensors, and Arduino’s new Make Your Uno kit. Finally, he reveals the Electromaker of the Month winners, led by Naveen’s snoring detection device using a Nordic Thingy:53.
