Hackaday editors Mike Szczys and Elliot Williams discuss a Casio DMCA controversy involving an ESP32-based calculator hack, a thermochromic clock built by Daniel Valluk at CERN using a 32x32 resistor grid, and George Hilliard's reverse engineering of a RioLink security camera using a SOIC socket. They also cover Mateo Pisani's capacitive touch modification for Nintendo Switch Joy-Cons, Stefan's use of paving stones to dampen 3D printer noise, and Leo Fernicky's prototyping tips with copper clad and Teflon wire. Finally, they review Chris Metal's modular bench tool system, Corey Collins' conduit-based CNC, and Tom Nardi's proposal for lunar landing pads using rocket exhaust and alumina.

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.
Hosts Jen Castillo and Alvaro Prieto discuss their pandemic-era projects, including Alvaro's recreation of his father's 7400-series digital clock, a USB-C power adapter using a Cypress chip, and a t-shirt quilt. Jen details her reverse engineering of a greeting card chip, her exploration of Chinese manufacturing via Alibaba, and her choreography of a remote dance piece. They also cover the cancellation of hardware conferences like Hackaday Supercon and HackRF, and recommend movies such as 'Mood Indigo' and '3 Idiots'.
The host discusses stretchable PCB research from Yale's Faboratory and Charles Lohr's PolyLMN project, which use liquid metal pastes to create circuits that stretch up to 4x their size. He covers the potential Raspberry Pi 500 keyboard computer, the Pimoroni Pico Plus 2 W featuring the new RP2350 chip and in-house RM2 Wi-Fi module, and the M5Stack Cardputer ESP32 devkit. The episode also highlights the ESP32 Rainbow ZX Spectrum on Crowd Supply, solderless PCB prototyping with Opulo's Lumen PNP, and the ethical resolution of Jeff Geerling's voice cloning incident by Elecrow.
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.
Dave Jones of EEVblog and Chris Gammell of Contextual Electronics discuss their upcoming in-person meeting in Australia and New Zealand, highlighting plans for maker meetups and tech tours. Jones details his firmware hack of the Keysight 1000X-Series oscilloscope to unlock higher bandwidth and sample rates, while also noting a footprint error in his Mixy Tube clock project. The conversation shifts to industry news, including the CIA's Vault 7 leaks, the use of silicon carbide electronics for Venus landers, and the security risks of IoT devices like the Cloud Pet teddy bear.
