MadLab has launched a soldering kit that delivers a functional recreation of a World War II German Enigma cryptography machine powered by a Raspberry Pi Pico's RP2040 microcontroller.
Pi Pico Rx is a modern electronic project inspired by the crystal radio. It describes how Pi Pico Rx, using a Raspberry Pi Pico, an analogue switch, and an op-amp, can create a simple yet capable SDR receiver covering LW, MW, and SW bands, capable of receiving signals from around the globe. The project is still in the experimental stage, with more technical details available in the provided documentation.
