Chris and Elecia question embedded systems then answer listener questions about embedded systems. They mostly agree except about one thing which, after some discussion, they agree upon. Mostly. Video of Cissy Strut cover where Chris plays all of the instruments Video where Elecia shows off some programmatic origami and simulation (not discussed but…
 
Alexandra Covor spoke with us about engineering, making, drawing, school, and what it means to be an artist. Alex’s projects are on GitHub and Hackster.io. Her electronics comics can be found as PikaComics on Instagram. The 2022 Open Hardware Summit named Alex as part of the Ada Lovelace Fellowship. Her favorite talk from the summit was Anuradha Re…
 
John Catsoulis is the founder of Udamonic and creator of the Forth-based Scamp development board. He spoke with us about Forth, electrical engineering, and writing a technical book Find out more about Udamonic’s Scamp at udamonic.com. There are some hardware projects under the Create menu. The Forth programming language is famous for its small size…
 
Laura Abbott of Oxide Computing spoke with us about a silicon bug in the ROM of the NXP LPC55, affecting the TrustZone. More information about the two issues are in the Oxide blog: Another vulnerability in the LPC55S69 ROM Exploiting Undocumented Hardware Blocks in the LPC55S69 More about LPC55S6x and their LPC55Sxx Secure Boot Ghidra is a software…

Tom Anderson returned to the show to describe how transistors and passives work. We discuss everything from vacuum tubes to diodes to transistors (PNP and NPN) to resistors and capacitors. We search for synonyms among the confusing terminology of cathodes, plates, emitters, anodes, grids, bases, and collectors. This was a tech heavy episode so litt…
