    Jul 25 2026

    Marine biologist Dr. Steven Haddock joins the show to share the alien, glowing, and transparent wonders of the deep ocean. We discuss his beautiful new book, The Radiant Sea, and explore the complex engineering and high-sensitivity optics required to capture living deep-sea creatures. Steve walks us through the evolutionary logic of biological light, how vantablack organisms trap photons in the dark, the horizontal sun-compass navigation of jellyfish blooms, and what it's like to play games underwater with giant Pacific octopuses and jumbo squids.

    Dr. Steven Haddock is a Senior Scientist at the Monterey Bay Aquarium Research Institute (MBARI) and an adjunct professor at UC Santa Cruz.

    Chris Svec returns to the show to discuss the messy, non-linear realities of engineering management and onboarding new college graduates. We explore why companies should bother hiring fresh grads in the first place, how to prevent junior developers from going dark when they get stuck, and why admitting ignorance publicly is an absolute workplace superpower. Along the way, we dive into managing genius firmware engineering hires, battling technical debt and software entropy, and why your development team shouldn't communicate solely through pull request comments. Chris Svec is the Director of Embedded Software Engineering at Insulet. If you're looking for an experienced leadership or management thought partner to help scale your development team, Chris Svec offers private coaching and consulting. You can reach him directly at the email given in the show (or hit the contact link and we'll forward your message along).

    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.

    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."

    526: Take A Taste Of Engineers
    May 28 2026

    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.
