Hackaday editors Elliot Williams and Tom Nardi discuss the ESP32-S31 microcontroller's dual RISC-V cores and Wi-Fi 6 capabilities, alongside the potential removal of i486 support in Linux 7.1. They explore a 'threadless ball screw' mechanism for linear motion, a hack connecting Bluetooth calipers to FreeCAD for real-time parametric modeling, and the history of early 3D printing filament production. The episode concludes with a discussion on long-term data storage options and the Artemis II mission around the Moon.

The host of The Electromaker Show reviews several maker projects, including Ralph S. Bacon’s exploration of wireless serial debugging, Carl Bugeja’s self-soldering PCB concept, and Ivan Miranda’s giant 3D-printed Lego go-kart. He also highlights the ZS Watch open-source smartwatch, the Puca DSP audio board, the FarPatch wireless debugger, and the newly announced ESP32 C6 module.
Dave Jones of EEV Blog and Chris Gammell of Contextual Electronics discuss the impact of AI on electronics engineering, using tools like Midjourney and ChatGPT to augment design and creative workflows. They analyze the new Espressif ESP32-P4 RISC-V microcontroller, noting its lack of integrated connectivity and potential to lower costs for high-performance embedded applications. The conversation also covers the physical limitations of satellite messaging, the trend of shrinking component sizes like 0603 capacitors, and practical advice for engineers navigating performance reviews and career growth.
Ian from Electromaker presents episode 77, highlighting the new Electromaker Educator series hosted by Robin Mitchell, which covers microcontroller platforms like STM32, AVR, and RP2040. The episode features Aaron Christophel’s project to flash Texas Instruments chips using an ESP32, and discusses the March Electromaker of the Month winners, including a DIY RP2040 Space Mouse and a retro arcade clock. It also covers Mitxela’s 1-inch HDMI second screen hack, the Roendi rotary encoder display on Crowd Supply, and the NXP Cup autonomous vehicle competition.
Hosts Dave Jones and Chris Gammell discuss a wide range of hardware topics, starting with Chris's preparation for Embedded World using FreeCAD and KeyCAD. They delve into Bluetooth Low Energy history and standards, then analyze the industry shift toward plug-in hybrids, citing Toyota's strategy. The conversation covers new silicon from Espressif, the TinyTapeOut project by Bitlooney, and Pete Bevilacqua's PowerMole Kickstarter, before concluding with a look at BeagleBoard.org's new Raspberry Pi-compatible board and a discussion on popular hobbyist components.
Host Ian reviews a mix of embedded hardware news, crowdfunding projects, and maker tutorials. He covers Nvidia's new Generative AI tools for robotics, the Tangara ESP32 music player on Crowd Supply, and Seeed Studio's high-refresh-rate Inkplate 6 Motion. The episode also highlights specific maker projects, including a DIY RC car using an ESP8266, a Silicon Labs gesture remote powered by Neuton.AI, and the open-source CLN17 stepper driver.
