I’m really into Pico / RP2040 based projects these days. Mostly environmental monitoring type of stuff.

This was fun to play with.

On the Pi side its mostly remote video surveillance stuff. Motion Eye OS on a Pi 3B+ or 4B. A couple are Pan tilt setups.  
I have a Pi5 with NVMe, a Pi 400, a couple Pi 4B’s, some 3B+'s 3A’s and Zeros.
