Hackaday editors Elliot Williams and Tom Nardi discuss the EsparGos project, an ESP32-based array that visualizes Wi-Fi signals for direction finding and passive radar. They cover Amazon's decision to disable direct Kindle book downloads, the history of the Access Bus as a pre-USB alternative, and a multi-layered hack running Linux inside Animal Crossing. The episode also features discussions on 3D-printed active electronic components, East German Severit glass, and the limitations of modern voice control systems.

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.
The host of The Electromaker Show covers several maker electronics news items, starting with a Raspberry Pi Pico project that generates PAL video by overclocking the RP2040 chip. He then highlights an Arduino-based digital clock made from 24 analog clocks and a deep-dive video by Dave's Garage on building a Pong console from scratch. The episode focuses heavily on Nordic Semiconductor's release of the nRF7002 DK, their first Wi-Fi 6 companion IC, and Espressif's announcement of the ESP32-C5, a general-purpose RISC-V microcontroller with no wireless connectivity.
The host discusses Naveen's project running Linux on an Arduino Nano ESP32 and Uno R4 Wi-Fi, where the ESP32 handles the OS and the Uno manages I/O. He highlights several upcycling projects from the Raspberry Pi blog, including a Tomy Turbo dashboard turned into an Outrun arcade cabinet, a Wurlitzer jukebox retrofitted with a Raspberry Pi, and an Udo X86 vintage radio. The episode features the LattePanda Sigma as Product of the Week, a powerful X86 single-board computer, and covers Seeed Studio's SenseCap T1000 LoRaWAN Kickstarter. Finally, he announces Edge Impulse's Imagine conference on edge AI.
The host discusses Jumperless, a software-defined breadboard by Kevin Santo Capuccio (Archetois) that uses analog crosspoint switches and an RP2040 to eliminate physical jumpers, featuring a browser-based Wokwi bridge. He highlights Scott W. Harden’s project enabling audio playback on an Arduino Uno R3 using only its 32KB flash, and Volos Projects’ ESP32 Nano handheld console using a GC9A01 circular display. The episode also covers the ZimaBlade server pre-launch from IceWhale, which supports DDR3/DDR4 RAM and GPU attachment for local AI, and Sipeed’s new RISC-V devices including the LycheePi 4A cluster, tablet, and console.
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.
