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.
If you have a 3D printer, ou can make a wifi enabled camera out of the zero 2W if you buy a small raspi cam module and connect it to a powerbank and or solarpanel. As a security camera or if you add some basic motion detection a nature/animal camera.
