Professor Cindy Harnett spoke to us about new and different sensors and actuators, primarily designed for soft robotics and fabricated with relatively low cost materials. Cindy is a professor of electrical and computer engineering at the University of Louisville where she runs the Harnett Lab . The papers we discussed are here . You can find a longer list of Cindy’s papers on Google Scholar . The video of the SESAME actuator is especially interesting. Transcript…

Debra Ansell joined us to talk about finding friends and exchanging neat gifts, accidentally tricking people into making unmanufacutable boards, and happy, blinking lights. Debra is usually known by the moniker GeekMomProjects (also her website is geekmomprojects.com ). She has been writing for Make Magazine . Debra won one of the SuperCon badge add-on awards so her poseable Bendy SAO will be available at SuperCon Europe. Some other things we mentioned: Seeed Studio XIAO board Adafruit QT Py Debra’s Remoticon talk about PCB structures Martin Oehler is Maketvee on YouTube and Mastodon Janet Hansen is on Mastodon and has an incredible Enlightened Designs wearables website. #makergiftexchange on your favorite social media platform And some upcoming events that promise to have lots of LEDs: Teardown 2025 | Crowd Supply (Jun ‘25) Portland Winter Light Festival (Feb ‘25) Transcript…

Elecia and Chris talk with each other about the state of Chris’ mind, what makes an embedded developer stand out, “LEGO block” based design, unit tests, and astronomy. Whew! Elecia was recently on the Changelog podcast, talking about the world of embedded systems . Chris has been working with Micropython (we talked with Damien George about Micropython on episode 456 ). He’s using a Pyboard to start, but is looking to move on to this board from Sparkfun. Wikipedia has a nice reference on what the pulse-per-second signal is all about . Elecia talked about her experience using CFFI to drive unit tests. She also talked about some facts from Information is Beautiful . Chris’ telescope is the ZWO Seestar S50 . There’s also a smaller Seestar S30 now which has a wider field-of-view. Title reference (Chris and Elecia both thoroughly enjoyed The Good Place, the TV show this is taken from.) Transcript…

Nathan Jones chatted with us about his proposal for a computer architecture book based on a 4-bit computer. Nathan found the 4-bit computer in the Hackaday SuperCon 2022 badge and was amazed by some of the ideas that folks implemented (see SuperCon Badge Hacking Awards Ceremony ). Nathan spoke at Hackaday SuperCon 2023 on the processor architecture , highlighting some of his ideas for a book. If you’d like to try your hand at the badge, find it on Nathan’s Voja4 Tindie page . Nathan also spoke recently at the Embedded Online Conference ( Building a Simple CLI , OOP in C , and The Power of a Look-up Table ) and the Teardown Conference ( Making Your Own MCU Boards and Building a Simple CLI ). If you have an idea you’d like to propose, check out O’Reilly’s proposal for a book or class . While you may not go with them, the proposal is a good place to get all of your ideas down. We mentioned a few other computer architecture books as competitors for Nathan’s proposed book: Computer Architecture: A Quantitative Approach by John L. Hennessy and David A. Patterson Introduction to Computing Systems: From bits & gates to C & beyond by Yale N. Patt and Sanjay J. Patel The Elements of Computing Systems , by Noam Nisan and Shimon Schocken (MIT Press) with supporting material and simulator on nand2tetris . Nathan also did a survey of the Embedded Slack community. You can gain access by becoming a Patreon or Kofi supporter . Transcript…

Nikolaus is a Professor of Computer Science at the University of Colorado, see his lab website (or his Wikipedia page ). We discussed Nikolaus’ Introduction to Robotics with Webots Specialization Coursera course (or YouTube Playlist ). These go along with his Introduction to Autonomous Robots (which can be compiled from source from github ). Masters of Computer Science online via University of Colorado and Georgia Tech . While the Arcbotics’ Sparki is no longer in production, Nikolaus also mentioned the Amazon Racer . Transcript…

Chris and Elecia discuss her origami art show, ponder PRs for solo developers, attempt to explain GDB debugging, and make a to-do list for getting rid of Kanga. Elecia is having an Origami Octopus Garden art show at the Aptos Public Library for the month of November, 2024. The postcard advertisement is below. There are more pictures on her Instagram ( @elecia_white ). The python tessellation generator is here . Memfault’s Interrupt Debugging Firmware with GDB post is a much more considered explanation of GDB and includes pointers to other resources (including using Python with GDB). Transcript…

Chris and Elecia chat about simulated robots, portents in the sky, the futility of making plans, and grad school. A problem with mics led us to delay the show with Shimon Schoken from Nand2Tetris (co-author of Elements of The Elements of Computing Systems: Building a Modern Computer from First Principles ). Look for that later in the year. Elecia is playing with Webots , a robotics physics simulator. Simpler than ROS’s Gazebo, it also can run in an online mode where you can run it on a browser, selecting between many different robots . Chris talked about processing his photos of Comet C/2023 A3 (Tsuchinshan–ATLAS) using PixInsight and Siril . Then we talked about grad school (including Georgia Tech’s reasonably affordable CS Master’s Degree ). Tony sent in this insect detector: Mothbox .

Rick Altherr spoke with us about high-speed control, complicated systems, and making quantum computers. If you want to know more about building quantum computers, take a listen to Rick’s MacroFab episode: The Nuts and Bolts of Quantum Computing . If you want to make your own quantum circuit simulator, it only takes 27 lines of Python: A Quantum Circuit Simulator in 27 Lines of Python . What about if you actually want to know about quantum computing? Rick suggests Quantum computing for the very curious while we look back at Embedded.fm 344: Superposition, Entanglement, and Interference with Kitty Yeung, talking about her Quantum Computing Comic book and Hackaday lecture series. Rick works for IonQ where they do trapped-ion quantum computing (there are different physics methods for making ions dance to the tune of quantum computing). If you want to talk to Rick, maybe to get his advice about your resume or career prospects, he sets aside a few hours each week to share his wisdom: https://calendly.com/mxshift You can also find Rick on Mastodon and LinkedIn . He was also the guest on 311: Attack Other People's Refrigerators about security hacking and mentoring. Transcript…

Chris and Elecia talk about their current adventures in conference talks, play dates, and skunks. Elecia’s talks are available on YouTube: Creating Chaos and Hard Faults : An introduction to hard fault handlings, stack overflows, and debugging hard bugs Introduction to Embedded Systems (O'Reilly Expert Webinar) : An introductions to… well, embedded systems These are both advertising for the 2nd edition of Elecia’s book, Making Embedded Systems: Design Patterns for Great Software . You can also find it on O’Reilly’s Learning System and probably read it with your 30 Day Trial ( here ). Chris got a handheld game console, the Playdate ( play.date ), and has been writing a game for it. There is an interesting looking MicroPython port for it . We also mentioned Tiny Tapeout Demoscene which sounds pretty neat. And KiCanvas where you can see KiCAD schematics without loading KiCAD. Our newsletter has been off but will be back to normal next week. The RSS feed is probably not fun to look at but Elecia’s Rebloginator shows some Python tools for parsing feeds. Neither the dog nor the skunk seem contrite. Transcript…
