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…

Amanda “w0z” Wozniak spoke with us about her career through biomedical engineering and startups. Amanda contributed a chapter to Building Open Source Hardware: DIY Manufacturing. (A book we spoke with Alicia Gibb about in #289.) Amanda’s chapter was titled Design Process: How to Get from Nothing to Something. For more information about the companie…
 
Chris and Elecia chat about tools, interrupts, and general happenings. Thank you to Newark for supporting the show! The part that was not guessed was an RF FET: MRF1K50HR5. Elecia found MCU on Eclipse (Eric Styger)’s tutorials on Visual Studio Code for C/C++ with ARM Cortex-M (Part 1). Embedded has a Patreon page where you can get access to the Sla…

Chris and Elecia talk about burnout, a SPI + RTOS bug, newsletters, receiving feedback, Elecia’s class, and listener projects. Elecia’s Making Embedded Systems course on Classpert is starting a new cohort on March 19th. She gave a live talk related to the class about looking beneath the surface of Arduino (YouTube version). She’s excited about the …
 
Reinhard Keil joined us to talk about creating the Keil compiler, the 8051 processor, Arm’s CMSIS, and the new cloud-based Keil Studio IDE. MDK-Community is a new free-for-non-commercial use, not-code-size restricted version of the Keil compiler (+ everything else). CMSIS is a set of open source components for use with Arm processors. The signal pr…
 
Shawn Hymel spoke to us about creating education videos and written tutorials; marketing by and for engineers; and bowties. You can find Shawn teaching FPGAs, RTOSs and other interesting topics on Digikey’s YouTube channel. Shawn also has two embedded Machine Learning courses on Coursera (free!).

Chris Svec of iRobot and Phillip Johnston of Embedded Artistry join Christopher and Elecia to talk about the hows and whys of estimating software schedules.. The article that started the discussion was Agile Otter’s Platitudes of Doom. You can participate in these sorts of discussions on the Embedded Slack Channel by supporting Embedded on Patreon.…
 
Matthew Liberty (@mliberty1) shared good advice for lowering power. We talk about different ways to measure current (Matt has a nice write-up) and things software can do to decrease power consumption. Sleeping is critical, of course, as is choosing your clock speed and setting the GPIOs to good states. Everything is fine until you start getting int…
