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.

My Pi2 is my Christmas Tree. I think the older version is discontinued, but they have this one:

It's super simple to put up and take down. :) I have an sd card with the software set up to automatically run the lights when booted. I keep a bluetooth dongle plugged in, and when a cron job recognizes that the bt dongle has been removed it shuts down the rpi. Simple solution and everyone who sees it loves it.
