Podcasts about circuitpython

This week, Hackaday Editors Elliot Williams and Tom Nardi start the episode off by discussing the latest CircuitPython developments before covering some impressive reverse engineering efforts, the benefits of modeling your projects in 3D, and some of the most incredible timepieces that have ever graced the pages of Hackaday. You'll also hear about the fascinating potential of combing 3D and UV printing, Linux on the ESP32, and a virtual TV station that pulls from the Internet Archive. The episode wraps up with a Hackaday Europe double-feature: one talk extols the virtues of keeping things simple through bare metal development, while the other covers off-world hacks and fixes that will make you want to sign up for Space Camp. Check out the links if you want to follow along, and as always, tell us what you think about this episode in the comments!  

This is a replay of The Bootloader's livestream on the Adafruit YouTube channel on CircuitPython Day. Tod and Paul take a look back at the last year and share some of their favorite CircuitPython projects and features. This episode has been slightly edited and we do use screensharing, so you may want to check out the video on YouTube.Show Notes00:00 Intro01:04 CircuitPython in the last year1:32 CircuitPython 10 Audio EffectsTing alternate CircuitPython voice effects firmware4:32 CircuitPython 10.1 and 10.2 updates4:45 MicroPython and upstreamMicroPython home page5:10 The Adafruit Fruit JamAdafruit Fruit Jam Learn GuideFruit Jam OS5:34 Sean Carolan's Pac-Man CloneSean on The CircuitPython Show6:31 Dan Cogliano's Z Machine and Zork8:27 Dan Cogliano's Fruit Jam ScreensaversMoon Miner9:22 Liz Clark's Fruit Jam Video Music PlayerAtari Video Music original hardware11:49 picogame by Vladimir SmitkaWrite-up of picogame on chiptron.eu16:31 Lorraine's Autonomous LEGO Train with CircuitPython and LIDARAmazon LIDAR example or dfrobotPython code for Raspberry Pi19:50 RV Circuit Studio by Armstrong Subero24:18 Liz Clark's Chiptune PlayerCircuitPython AY8912 libraryVGM fan websites27:39 PicoTTYEmbedded Systems News story30:37 Wrap-up

In this episode of Teaching Python, Kelly Schuster-Paredes and Julian Sequeira are joined by engineer and maker Todd Kurt to discuss what happens when code leaves the screen and starts interacting with the physical world. The conversation centers on CircuitPython, MicroPython, and physical computing, with a focus on how these tools are used in classrooms and maker projects. Todd explains his background in engineering, web development, and open source hardware, including his work on LED devices and his recent focus on CircuitPython. He describes the differences between CircuitPython and MicroPython, emphasizing that CircuitPython is designed to feel closer to desktop Python and to support teaching, while MicroPython makes more efficiency-focused tradeoffs. The discussion also covers the practical challenges of hardware-based learning. Todd and the hosts talk about bootloaders, UF2 files, board compatibility, library management, and common mistakes such as using the wrong cable, the wrong board file, or wiring power and ground incorrectly. They note that these issues can make hardware feel frustrating, especially for beginners and teachers preparing classroom kits. Kelly and Julian share their classroom experiences, including using preloaded boards, NeoPixels, sensors, and simple student-designed projects. They discuss how hardware can support troubleshooting skills, file-system awareness, and persistence, and why students often engage more when they are building something tangible, such as a sensor-based wearable or a small robot. The episode also includes Todd's stories about early embedded work, including a costly lab mistake, and his involvement in hardware that contributed to space missions. He closes by describing a compact synthesizer project built around a Raspberry Pi Pico and by noting that he shares work through his website and online accounts.Special Guest: Tod Kurt.
