We spoke with Peter Griffin about Jumperless Breadboards, no-install GUI development, Excel, and puppies. Jumperless Breadboard at CrowdSupply Colab GUI for Jumperless Breadboard Website GUI for Jumperless Breadboard Excel GUI for Jumperless Breadboard (though it has some USB DTR issues as noted in the show: Jumperless_V5_GUI (Shared).xlsx. Note Microsoft Datastreamer is a serial interface to Excel  Teardown 2025 will have talks up soon! Cory Doctorow wrote about ‘Enshittification’ in Wired. We didn’t bleep the word for this episode since it’s becoming an essential part of tech criticism. The Flag of Maryland. You know what you did. Joel Spolsky’s You Suck at Excel Miso Come Here (Instagram, TikTok) shows puppy communication buttons.

It’s another episode with Elecia and Chris. This week they discuss people that have influenced their lives and careers, thinking about past career choices and regrets therein, identities, the Embedded Slack book club, and electronic projects. Chris is currently taking Dogbotic’s DIY Rhythm Widgets course which covers making an analog drum machine from components. We had Dogbotic founder Kirk Pearson on the show on Episode 491. Elecia mentioned the book that the Embedded Slack #book-club channel is working through, Data Driven Science & Engineering Machine Learning, Dynamical Systems, and Control, which you can find for free at https://databookuw.com along with code and examples. The group is two sessions in but if you want to join late, join the Slack group via Patreon or Ko-Fi. You can subscribe to the newsletter here. Transcript

Emily Lovell spoke with us about teaching how to contribute to open source, including her own experience creating the LilyTiny as a Master’s student and researching the impact as a PhD student.  The LilyTiny work was done in conjunction with Leah Buechley (Embedded episode 382). See the paper The LilyTiny: A Case Study in Expanding Access to Electronic Textiles or watch the video. UCSC Open Source Program Office (note this is different from the Center for Research in Open Source Software (CROSS) that we spoke about with Carl Maltzahn (Episode 285). Emily recommended the curriculum from TeachingOpenSource.org.  Emily’s other life is at EP Custom Pickups and Aberdeen Guitars. She spoke on a lutherie panel at NAMM.

The hosts dive into the adaptation of the 'Murderbot Diaries,' discussing casting choices and the subtleties of character dynamics. They explore the complexities of AI tools, humorously tackling their limitations in coding and legal scenarios. E-bikes come into play with entertaining biking anecdotes and tech-friendly infrastructure. The conversation turns technical, examining control systems and the delicate balance between empirical methods and advanced mathematics in engineering. It's a blend of thought-provoking insights and light-hearted stories.

We spoke with ecologist Dr. Meredith Palmer and embedded engineer Akiba about lions, terror, and technology.  Akiba works for FreakLabs.org on global conservation projects. We talked about their Boombox which Meredith uses to create experiments to map the landscape of fear in predator/prey relationships. While this may look like pranking animals with jump scares, well, there is real science being done.  What would it look like to be smooched by a lioness? (Video) Bird hears lion, decides to go over there (Video) Checking the reflexes of some zebras and other critters (Video) Hyena eating camara (Video) These are lots of fun to watch and you can find the freshest ones and help out science by categorizing some at Snapshot Safari. Or skip to using the data on Lila.science (Snapshot Safari 2024 data). Check out Meredith’s website for more github and Data Dryad links to data and science.  If you want to get involved, Wildlabs.net has discussions around conservation technology. There is also a Slack group by Sara Beery focusing on AI for conservation. Elecia mentioned David Quammen, an author who writes a lot about biology and ecology. And now, a guy gives birth to a botfly. Transcript If you’re interested in the intersection of neuroscience and engineering, you might want to check out what Mouser Electronics is doing with Brain-Computer Interfaces. It’s all about how you can control machines with your mind, and it’s one of the coolest areas of innovation right now. Mouser’s Empowering Innovation Together site has great content on BCIs, from videos to in-depth articles and podcasts that break down the tech. If this piques your curiosity, head over to Mouser.com/empowering-innovation and explore what’s happening with BCI and other exciting developments in the world of design and engineering.

In this discussion, Komathi Sundaram, a Principal Software Engineer at Cruise, shares her passion for software testing and automation. She dives into the exciting world of bug discovery and contrasts the roles of developers and testers. Topics include the importance of continuous integration, hardware-in-the-loop testing, and innovative simulation tools like WalkWe. Komathi also emphasizes effective communication in teams and the evolving dynamics between testers and developers, making the technical talk surprisingly engaging.

In this episode, Janet Hansen, an LED artist and founder of Enlighted Designs, brings her passion for lighted clothing to the spotlight. She shares her journey from engineering to designing striking illuminated garments for the entertainment industry. Highlighting stories from working with Daft Punk, she discusses the intriguing blend of technology and art. Janet also dives into the creative process, addressing both the joys and challenges of integrating electronics into costume design while embracing her artistic identity amidst the demands of commercial work.

At the end of this week’s show, Elecia reads a Winnie the Pooh poem as Cookie Monster death metal. Before that, Chris and Elecia chat about mental health, journaling, personal projects, and listener questions.  Please sign up for the Nordic Giveaway!  You can also sign up for the Embedded newsletter. Maybe now with job postings? Elecia’s journaling notebook is this one on JetPens (which is where she gets her nice pens and some of her stickers and washi tape).  From discussing some listener messages, we mentioned: Matt Keeter’s talk on debuggability in production where you don’t have access to the system that is faulting (video and slides) Letter boards (in the Adirondacks), see those in action here Wokwi simulator is a great place to get more embedded experience without buying all the kits. Christopher has said that there will not, definitely not, under any circumstances, be a whole death metal album of Winnie the Pooh poems. Elecia is practicing anyway.  Transcript Nordic Semiconductor has been the driving force for Bluetooth Low Energy MCUs and wireless SoCs since the early 2010s, and they offer solutions for low-power Wi-Fi and global Cellular IoT as well.
