Stay ConnectedI am Elecia White alongside Christopher White. We’re here to chat about the interests, careers, and lives of engineers, artists, educators and makers. Our diverse guest list includes names you may have heard and engineers working quietly in the trenches. Either way, they are knowledgeable, enthusiastic, and inspiring.
We’d love to share our enthusiasm for science, technology, engineering, art, and math (STEAM).

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 companies we discussed, check out Amanda's LinkedIn page.
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 Slack group. The book club is starting Prototype to Product: A Practical Guide for Getting to Market by Alan Cohen.
Wokwi Raspberry Pi Pico projects from Elecia: Command Line Interface and PWM Experiments with Logic Analyzer
Phillip Johnston of Embedded Artistry and Tyler Hoffman from Memfault are kicking off a quarterly embedded discussion panel. This month is about building embedded systems at scale using device metrics: Embedded Device Observability Metrics Panel
Jonathan Beri from Golioth created instructions on how to use USB from WSL2.
Thank you to Newark for sponsoring this episode of Embedded!
Dr. Shirley Davis spoke with us about her book: Diversity, Equity & Inclusion For Dummies.
Dr. Davis is a speaker and consultant on diversity, equity, and inclusion topics; her website is drshirleydavis.com.
Dr. Davis' books include:
This week we talk about CircuitPython with Adafruit's Kattni Rembor and Scott Shawcroft.
The suggested first board is CircuitPlayground Express with LEDs, sensors, and buttons. CircuitPython is also available for many other boards including the BLE Feather (NRF52832).
For a basic introduction take a look at What is CircuitPython and see some example scripts. To dig a little deeper, check out the many resources in Awesome CircuitPython. The whole thing is open source so you can see their code. If you are thinking about contributing (or just want some fun chats), get in touch on the CircuitPython channel of the Adafruit Discord server: adafru.it/discord
Many of the language's design choices favor ease-of-use over ready-for-production. Imagine teaching an intro to programming class without worrying what computers will be used or how to get compilers installed on everyone's machines before time runs out.
One final note: Kattni did a project that gave us the show title: Piano in the Key of Lime. After we finished recording, Chris asked her why she didn't add a kiwi fruit to her mix… Kattni explained she had limes and they were small. Chris only wanted a different fruit so she could rename it Piano in the Kiwi of Lime. It is always sad when we stop recording too early.
Machine learning engineer and science fiction author S. B. Divya joined us to talk about artificial intelligence, robotics, and humanity.
Divya's first full-length book is Machinehood which has been nominated for a Nebula (as was her novella Runtime).
You can find more about Divya on her website (sbdivya.com) or on her Wikipedia page.
Divya also co-hosted EscapePod, a podcast of science fiction stories.
Mihir Shah of Royal Circuits joined us to talk about how PCBs are fabricated and how companies are funded. Mihir was CEO of InspectAR before they were acquired by Cadence.
Mihir works for Royal Circuits and runs a newsletter called TheAnalog.io
We talked about InspectAR on Embedded 384: What Is a Board File? with Liam Cadigan.
This episode is sponsored by Newark, a leading international distributor of industrial and electronic components. From design and testing to production and maintenance, discover why so many choose to partner with Newark!
Jorvon Moss (Odd Jayy) joined us to talk about making robots, steampunk aesthetics, uploading consciousness to AIs, and the importance of drawing.
You can find Jay on Twitter (@Odd_Jayy) and Instagram (@odd_jayy). He's been moving his Hackster projects over to Digikey's Maker.io space: www.digikey.com/en/maker. Jay's projects are collected here.
Elecia brought up the science fiction book Machinehood by S. B. Divya. Jay returned with Martha Well's Murderbot Diaries.
Jay mentioned Mycroft.ai, open source voice assistant. Jay was interviewed by Make Magazine (article). He was on the cover of the magazine; the YouTube video where he was informed was heartwarming.
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 Wokwi Raspberry Pi Pico simulator with C.

Chris Lott wrote a Hackaday article about episode 404: Uppercase A, Lowercase R M with Reinhard Keil.
Elecia enjoyed Thanks for the Feedback: The Science and Art of Receiving Feedback by Douglas Stone and Sheila Heen.
Serial Wombat peripheral expander for Arduino will be on Kickstarter soon
Chris wanted machine readable datasheets, listener Nick responds with Cyanobyte on github.
Infineon (previously Cypress) PSoC (wiki) is a chip/FPGA thing. We talked with Patrick Kane about it in episode 32: Woo Woo Woo
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 processing and neural net components are optimized for speedy use. The SVD and DAP components are used by tool vendors so there may be components you care about more than others.
Keil Studio is Arm's new cloud-based IDE with a debugger that connects to boards on your desk: keil.arm.com. Reinhard talks more about the advantages of cloud-based development in this white paper.
Arm Virtual Hardware has multiple integrations, the official product page is www.arm.com/virtual-hardware. The MDK integration and nifty examples are described in the press release.
Reinhard mentioned the Ethos-U65 processor for neural networks.
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!).
Or start at his personal site: shawnhymel.com where you can find written tutorials like How to Set Up Raspberry Pi Pico C/C++ Toolchain on Windows with VS Code.
Shawn talked about Discovery-Driven Growth: A Breakthrough Process to Reduce Risk and Seize Opportunity by Rita Gunther McGrath and Ian C. Macmillan. He referenced Blue Ocean Strategy: How to Create Uncontested Market Space and Make the Competition Irrelevant by W. Chan Kim and Renée A. Mauborgne
