So most of my raspberry pi 4’s are deployed. But I still have a 3B, Zero 2W, Zero, 400 and a 1A that I have that I’m not doing anything with. I don’t know what would be a good project to use them with. Looking for some inspiration/ideas.

Edit: my current 4’s are hosting my pi hole, homebridge and Immich frame.

You might be able to make an ADSB reciever. It's transponder signals that power sites like ADSB Exchange
