A project by Martin Pittermann demonstrates how to build a sophisticated ultrasound sensor using a Raspberry Pi Pico and basic components, employing Frequency-Modulated Continuous Wave (FMCW) radar techniques for distance measurement and potential wind speed detection.
Anfractuosity built a hyperspectral camera, the Waverider, using a miniature USB spectrometer, a stepper-driven x-y stage, and a Raspberry Pi Pico. It scans spectra one pixel at a time, taking nearly 19 hours for a 400x400 image but capturing more than just RGB values per pixel.
