Hosts Chris Gammell and Dave Jones discuss the Hamvention electronics convention, highlighting the aging demographic of attendees and the role of Arduino in revitalizing the hobby. They detail a debugging challenge where Jones identified that an Analog Devices op-amp's offset voltage was dependent on the power supply rail, a flaw not clearly documented in the datasheet. The conversation also covers Jerry Holkins' upcoming augmented reality glasses project, the low-cost Georgia Tech/edX online master's degree, and recent news regarding Arduino's Linux capabilities and Formlabs' successful Kickstarter.

Other shows on the same ground, closest first.
Hosts Elecia White and Christopher White discuss the show's new transcript availability, the technical details of using a Cricut Maker with SVG files, and the legal and technical risks of using the Arduino IDE for professional products. They also cover debugging strategies for intermittent bugs and share personal experiences with focus, motivation, and executive function challenges.
Jen and Alvaro interview Chris Svec of SEGGER, Josh Lifton of Crowd Supply, Richard Whitney of the Happy Robot Company, Alex Glow of Hackster, and Chris Gammell of Contextual Electronics at the 2018 Hackaday Superconference. They discuss reverse engineering tools like the SEGGER J-Link and Analog Discovery 2, and projects including the Open Steno Project, Charmware, and the Happy Robot's cuddly robots. The guests share personal anecdotes about electronics mishaps, such as shorting high-voltage rails and dealing with thermal printer integration issues at Crowd Supply.
Hosts Alicia and Christopher White celebrate the 200th episode of Embedded.fm with a panel of former guests: Alvaro Prieto, Andrei Chichak, Elizabeth Brenner, Chris Svec, and Chris Gammell. The group discusses their favorite embedded tools, including Saleae logic analyzers, Digilent Analog Discovery, Beyond Compare, and HP16C calculators, while sharing humorous field stories and interview anecdotes. They reflect on the joys of working in embedded systems, such as seeing products on retail shelves and the satisfaction of debugging complex hardware-software interactions.
Mike Szczys and Elliot Williams discuss the closure of Maker Media, a GPS hardware failure grounding flights, and a Raspberry Pi 3 B+ power management chip vulnerability. They also review community hacks including a vintage speech synthesizer, an SOIC test clip debug connector, and a mechanical drum machine, before analyzing the Takata airbag scandal.
Hosts Amelia Cook and Christopher White reunite with guests Star Simpson and Jen Costillo to reflect on the evolution of the hardware hobbyist landscape over the two years since their first appearance. Star Simpson, who works at Orion, discusses her wearable device project and her open-source FPGA toolchain initiative called Balboa, while also recounting the challenges of crowdfunding the Octopart reference card. The group analyzes the shifting attitudes toward privacy and security in the Internet of Things, the rise of accessible prototyping tools like 3D printing and Crowd Supply, and the changing ecosystem of development boards including the Odroid and Arduino.
