Hackaday editors Mike Szczys and Elliot Williams discuss several hardware projects, including Elliot's discovery of Chinese clone STM32 microcontrollers (CS32, GD32) on 'Blue Pill' boards that caused programming failures with standard tools. They also explore Top Point TV's zero-ohm jumpers in various SOT packages, which offer creative but risky PCB layout solutions. The episode highlights a 3D-printed Selectric typewriter ball, an ESP32-based time-lapse camera project by Bitlooney that battles a shared GPIO bug, and a detailed look at RF modulation using RTLSDR dongles.

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.
Ian from Dangerous Prototypes discusses the evolution of the BusPirate, culminating in the BusPirate 5, which utilizes an RP2040 microcontroller and features an LCD, adjustable power supply, and current sensing. He details the creation of DirtyPCBs and other services like DirtyCables, explaining how he automated PCB ordering in Shenzhen to disrupt the market. Ian also shares anecdotes about his time in Huaqiangbei, including the 'Expressway to Pleasure' project and his experiences with local manufacturing quirks.
Corey discusses his ongoing ping pong scoreboard project, which uses discrete logic chips like the CD4026 and struggles with CD4518 counters due to clock rise time violations at 12V. He details his debugging process involving breadboards, hex buffers, and the decision to design a PCB using Fritzing. Meanwhile, Karl introduces the STM32F723ZE microcontroller, highlighting its built-in USB High-Speed PHY, but warns of software library incompatibilities, and outlines his own project: a custom CNC Raspberry Pi hat integrating an Arduino and RS485 communication for a variable frequency drive.
Dave Jones and Chris Gammell perform a teardown of the Rode Wireless Go 2 receiver, identifying a confusing mix of chips from Dialog Semiconductor, Nordic Semiconductor, and SmartCore. They discuss the implications of 3G network sunsets on devices like insurance trackers and solar monitors, and analyze the end-of-life announcement for the EDA tool EAGLE by Autodesk. The episode concludes with a look at a vintage Intergraph Corporation PCB, highlighting the density and routing techniques of older hardware.
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.
