I 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).

    Goldfish Chunks

    Tyler Hoffman returns to the show to discuss diagnostics and observability data in embedded systems. We catch up on his life after startup acquisition, explore the hows and whys of keeping product data separate from operational data, and consider the realities of fleet management at scale.  Tyler is the co-founder of Memfault. Memfault was acquired by Nordic Semiconductor about a year ago. While Nordic has nRF Cloud as a smaller scale solution for Nordic devices (~100 devices), Memfault will continue to maintain support for non-Nordic platforms as well. During the discussion, Tyler advocates for a "device-in-control" philosophy, emphasizing that edge devices should retain the intelligence to manage their own firmware updates and telemetry. We also discuss the practical constraints of remote fleet debugging, outlining why tools built for high-bandwidth web infrastructure will quickly bankrupt an IoT company, and identifying exactly when a project is too low-bandwidth, or too small, to justify an external observability platform. Christopher shares his recent experiences with Memfault which leads to a discussion of chunks, flash memory buffers and MDS. The Memfault Diagnostic Service (MDS) is a standardized way for BLE devices to send the chunk payloads to a gateway device (mobile phone) which can then forward the data to the Memfault cloud. If you want a deep dive into the reasoning around starting Memfault, Tyler was on Embedded.fm episodes 390: Irresponsible At the Time and 395: I Can No Longer Play Ping Pong. Reaching back into the archives, Elecia, Tyler, and Phillip Johnston were on the Memfault Coredump Sessions podcast, a special crosspost with Embedded.fm, episode 451: From Concept to Launch  You can also find technical deep dives on Memfault's Interrupt blog.

    At The Jellyfish Conference

    Chris and Elecia talk about pushing out of their comfort zone, networking advice, adding STARs and action verbs to resumes, using rust, thermo forming plastics, soldering together audio gear, and winning awards.  If you are looking for an update to your resume or are interviewing for a new job and you haven't heard of the STAR method (Situation, Task, Action, Result), it is a good way to formulate what you've done in a way that helps people see your impact. The Rutgers College Career Development Center has a STAR description that includes how to take your current, boring "did the task" resume bullet point and move it into STAR format and then into resume format to say "got great things done". There are lots of examples of STAR in practice (ex 1, ex 2). We mainly talked about resumes but it is very useful for having coherent stories during interviews. (Search "STAR resume", "STAR interview", "STAR engineering" to find a presentation that works for you. The college career sites are probably the best ones I've found.) On the topic of resumes, if you don't know about resume action verbs, let us share some lists that will make writing your resume 25% less painful. Again, college career development centers have the best ones (Harvard Business School's action verb list is good for managers, Penn State has a nice set of verbs for engineering or see University of Houston's verb list for engineering.) And on the topic of interviewing and networking, do you have an elevator pitch for yourself? A short introduction of who you are? It is really handy to have that for conferences as well. Princeton has a short write up on putting one together; UPenn has a long write up (ironic given the topic but still useful). Will Chris be adding the Rust language to his resume? Too early to tell. He's been learning with Rust for Embedded C Programmers - OpenTitan Documentation.  Elecia has been playing with origami molded fabrics, as learned on Instructable Paper Mold Origami Fabrics 3.  The term on Instagram seems to be #plissage and it is covered in (super famous origami guy) Paul Jackson's encyclopedic Complete Pleats.  Chris has built a Colour Duo 2-Channel Colour Channel Strip Kit (a preamp with modifiable analog processing). This kit is from DIY Recording Equipment. He's enjoying working with it while recording music.  After Elecia's New Year's Resolution to apply for awards, we won a Communicator Award for Individual Episodes-Science & Technology, Distinction 2026 for an episode about engineering the landscape of fear and conservation technology in the wild: 501: Inside the Armpit of a Giraffe. This was quite the honor but after some consideration, we are even more honored to be nominated by listeners for the IEEE Educational Activities Board (EAB) Meritorious Achievement Award in Outreach and Informal Education. This award "recognizes IEEE members who volunteer their time and effort to improve the informal education community, helping to promote engineering to students, parents, and the general public." Having fulfilled the objective and gone beyond, Elecia is still planning to apply for the AAAS Kavli Science Journalism Awards where we'll need to find one or two episodes from July 2025 to July 2026 that show off "scientific accuracy, initiative, originality, clarity of interpretation, and value in fostering a better public understanding of science and its impact."

    Take A Taste Of Engineers

    Dr. Victoria Serrano spoke with us about STEM outreach, fostering curiosity, and inspiring students with engineering education. Victoria is a professor at the Technological University of Panama (her faculty page: UTP | Dra. Victoria Serrano). Her youtube channel is CIATEC PANAMA which talks about circuits, electronics, and robotics. The channel goes along with her ciatecpanama.com website which shows the types of courses and outreach she does with Arduino UNOs and other low cost equipment.  Victoria is also a Fulbright Scholar, an IEEE STEM Champion 2023, and Honorable Mention IEEE Rising Stars Conference 2024. She also received the IEEE EAB Meritorious Achievement Award in Outreach and Informal Education in 2019 (the award Elecia and Chris believe is related to their work on Embedded.fm and for which they were honored to be nominated). The final quote was from Haben Girma's book: Haben: The Deafblind Woman Who Conquered Harvard Law.  Transcript

    Some Sort of Metal

    Dr. Tom Williams spoke with us about robots, ethics, teaching, and books. Then we talked about mines, umpires, water, and more books. Tom is the author of Degrees of Freedom: On Robotics and Social Justice (free at MIT Press: Degrees of Freedom: On Robotics and Social Justice!).  As part of the discussion, we talked about some other books and media: Nonfiction: Sex, Race, and Robots: How to Be Human in the Age of AI by Ayanna Howard (Embedded episodes 367: Data of Our Lives and 207: I Love My Robot Monkey Head) Embodied AI Safety: Reimagining safety engineering for artificial intelligence in physical systems by Philip Koopman (related Embedded episode 514: Just Turn Off All the Computers)  Atlas of AI: Power, Politics, and the Planetary Costs of Artificial Intelligence by Kate Crawford Waki Kamino's research on robot umpires: Beyond Accuracy: Rethinking the Value of AI in Decision-Making Through Baseball's Automated Ball-Strike (ABS) System (or see the summary in the Cornell Chronicle: AI on deck: assessing impact of MLB's new ball-strike system) Fiction: A Psalm for the Wild-Built by Becky Chalmers  Platform Decay (The Murderbot Diaries Book 8) by Martha Wells (Embedded episode 432: Robot Bechdel Test)  Death of the Author by Nnedi Okorafor The Good Place TV show was mentioned a few times as an introduction to ethics for people who prefer their education crammed with amusement. Critical Role web series There was a discussion about water use in AI. Tom recommends Why is Everyone So Wrong About AI Water Use?? while Elecia unsurprisingly mispronounces synecdoche.  Tom is a computer science professor at the Colorado School of Mines where he runs the Mines Interactive Robotics Research Lab (MIRROR lab). See also Tom's page on mines.edu. The final quote is from an essay written by Karel Capek and translated to English in in The Man Who Coined the Word "Robot" Defends Himself - IEEE Spectrum.

    This Isn't a Movie

    Nathan Jones spoke with us about hardware security, motivation, conference talks, and writing. Nathan wrote an in-depth series of posts about the benefits of superloops vs RTOS: You Don't Need an RTOS (Part 1), Part 2, Part 3, and Part 4. He also wrote about How Hardware Gets Hacked (Part 1) and Part 2 which discusses the MITRE embedded CTF (Capture the Flag) challenge. See his EmbeddedRelated profile and Digikey profile. And Nathan's excellent Embedded for Everyone Github repo. Nathan recommends The Hardware Hacking Handbook by Jasper van Woudenberg and Colin O'Flynn. It is an excellent resource on embedded security. We spoke with Jasper about the book in 431: Becoming More of a Smurf and with Colin about the Chip Whisperer in 286: Twenty Cans of Gas. The European Cyber Resilience Act (CRA) has specific features that are required to be implemented by all devices that want the safety CE label. This is important for products shipping to Europe. If you are going to the Embedded Online Conference, you can get a discount with the code JONES100. Nathan will be giving a workshop on the Chip Whisperer Nano. (Recent guest Mark Omo will also be presenting: Security for the Rest of Us: What Matters and Where to Start.) Another conference for the security-minded is Hardwear.io which is in Santa Clara, CA, USA at the end of May and in Amsterdam in November. Last year, Nathan spoke about Exception Handling for EOC 2025 (video). Elecia mentioned her own Creating Chaos and Hard Faults from EOC 2024. The Embedded Slack book club is reading The Pragmatic Programmer, 20th Anniversary Edition. Well, some of us are just watching.  The quote came from Elizabeth Bear's Ancestral Night (White Space) which is part of a series with some neat mechanics around brain chemistry.  Transcript

    Bad Experience With Donuts

    Chris and Elecia chat about Leapfrog toys, things they like, large company politics, awards, and open source governance.  The Toy Story 5 Trailer with LilyPad toy which is suspiciously similar to the LeapFrog LeapPad tablet. Which is different from the original LeapPad which had cartridges and capacitive touch (capacitive touch was used on the globe as well… the latest globe also has a screen). Why does Elecia want an award? Who knows? But right now, she's getting ready for a listener to nominate the show (Chris and Elecia) for IEEE's Meritorious Achievement Award in Outreach and Informal Education. Probably. But we've got nominators and endorsers so that's mostly sorted. She also signed Embedded up for the Women Podcasters Award which is a popularity contest. You can vote here: www.womenpodcasters.com/awards-voting. The show is under the Science Podcasters category. Some things we like: Ctrl-R: In a command shell, ctrl-r searches your history. Better than ! because you don't have to remember as much. Data bars in Excel: This can create a plot of your data in the column. Merlin Bird ID: Want to know what bird is making that sound? Want to know the name of the bird you just saw? Merlin Bird ID is a free app that is amazing. Plucky Cards: Want to have a 1:1 where you talk about more than your status? Choose a card, any card. Or maybe just look through and have a 1:1 by yourself Just reading about Bunnie Huang's new RISCV board Dabao Evaluation Board for Baochip-1x taught us things! We're not sure what we'd use it for yet but it does spark a few ideas.  The Embedded.fm Patreon Slack book club is reading Pragmatic Programmer 20th Anniversary Edition. Talking about open source projects and governance models, we referenced three contributing guidelines: Valetudo, ESPHome, and Zephyr. Some later research led to Leadership and Governance | Open Source Guides and presentation by Cornelius Schumacher – The spectrum of FOSS governance models (Slides). The link between the politics associated with the size of companies and the open source governance models clearly needs a bit more thought. Transcript

    The Information Is In Poop

    Sonia Grego speaks with us about a topic no one likes to talk about, but could be used to monitor personal dietary health and widespread disease outbreaks. Toilets! Sonia leads Duke University's Smart Toilet Lab and the spin out Coprata which makes the Microbiome Activity Tracker.  As discussed in the show, when developing a project far from where it will be deployed, there are many common issues. The Lessons Learned chapter of Sonia's recent book gives an excellent introduction to the unexpected environment far from the comfort of desks. The book is (free online!) Engineering Field Testing of Non-Sewered Sanitation Systems: Compendium of Lessons Learned,  See Sonia Grego at  Duke Electrical & Computer Engineering, the Smart Toilet Lab  as well as Sonia's company Coprata.  Some terms that came up in the show: Coprolite: fossilized excrement (Wikipedia entry has great(?) pics!) Scatological: material, humor, or language that relates directly to bodily waste Helminths: parasitic worms including roundworms, tapeworms, and fluke (oh look. more great images on Wiki entry) Poop jokes Transcript

    Are You The Tiny Domino?

    Kenneth Finnegan entertained us with stories about accidentally contributing to the internet's ability to network. Wondering how the internet works? All those terms about IPv4, IPv6, BGP, OSPF, CDN and other alphabet  soup? Check out the YouTube videos by NetworkChuck. Kenneth writes about his adventures on his blog, The Life of Kenneth. Some of the posts related to this show are: Creating an Internet Exchange for Even More Fun and Less Profit Building an Anycast Secondary DNS Service  Building the Micro Mirror Free Software CDN  We also mention FCIX aka fcix.net or the Fremont Cabal Internet Exchange You can also find Kenneth at @kwf@social.afront.org where you will find more about half-dollars, nickels, and trains. If you also secretly long to run a locomotive, take a look at the Run-A-Locomotive program at WPRM. The title is related to the XKCD comic 2347: Dependency. Transcript
