Hackaday editors Mike Szczys and Elliot Williams discuss a range of hardware hacks, including Ben Heck's logic-chip solution for WS2812 Neopixel timing and Wayne Holder's ATtiny10 firmware alternative. They analyze the accuracy of temperature-compensated real-time clock chips like the DS3231 and PCF2129, and highlight Fran Pirnos's DIY 3D CT scanner built from a dental X-ray tube. The episode also covers the end of Airbus A380 production, skepticism regarding DSRC vehicle-to-vehicle communication, and the growing crisis of global e-waste.

Hosts Elecia White and Christopher White discuss the technical implications of the 2038 time bug, the utility of the 'single-file libraries' GitHub repository for embedded development, and Christopher's hands-on MIDI project using an STM32 NUCLEO-144 board. Elecia also shares her exploration of Tiny ML for PID controller tuning and her attempt to apply for a NASA NIAC grant using curved crease origami for sensor systems.
Chris Gammell of Contextual Electronics and Dave Jones of EEVlog discuss various hardware topics, including Gammell's work with the CH32V003 microcontroller and RISC-V ecosystem, and Jones's troubleshooting of a Maddie Mac pool robot. They explore the technical details of 32-bit audio recording in microphones, the ease of setting up a Home Assistant smart home system using Zigbee, and the reliability issues of wireless light controllers. The conversation also covers the use of NRF24 radio modules, the physics of relativistic time dilation, and critiques of consumer devices like the Humane AI Pin and Apple Vision Pro.
The host of The Electromaker Show presents a roundup of maker electronics news, including a DIY UPDI programmer for ATtiny chips, a quiet 3D printing guide by Matt from Not Enough Tech, and a USB paper punch tape reader. He highlights crowdfunding projects like the Noctis & Aurel educational robots and the PlainDAQ precision DAQ module for the Raspberry Pi Pico, alongside Pine64's open-source PineSound audio dev board and the Vintage Computer Festival East.
Elecia White and Christopher White discuss Christopher's recent Kickstarter fulfillment, his learning journey with Blender for 3D graphics, and the importance of understanding Make and CMake for embedded build systems. They answer listener questions regarding unusual microcontrollers, specifically detailing a painful experience with Dallas Semiconductor 1-Wire authentication chips that turned out to be counterfeit. The episode also covers TCP/IP implementation on microcontrollers using lwIP and the challenges of sensor data interpretation.
Dave Jones and Chris Gammell discuss recent tech hype, including debunking viral claims about the 'Water Cube' dehumidifier and beta-voltaic 'nuclear diamond' batteries. They cover the merger of Evil Mad Scientist and Bantam Tools, a side-channel security vulnerability affecting ESP32 microcontrollers, and the acquisition of a used TVM pick-and-place machine. The conversation also touches on power grid issues, CAD software choices like Fusion 360 and Onshape, and the failure of solar roadways.
