## Summary

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.
