This project really combines a few of our favourite things, with MicroPython, 3D-printed parts, and a load of electronic goodies from Pimoroni: a LiPo Amigo Pro charger, a DS-959MG servo, a Display Pack 2.0 for Pico, a 400mAh battery, and a Pico Proto prototyping board. Oh, and a Raspberry Pi Pico W.

Just like in the film Ghostbusters, the PKE meter raises and lowers its arms as a response to the strength of a nearby signal, though in the case of this build, it’s looking for WiFi signal rather than ectoplasmic activity.
