My old iPhone 13 is kind if just sitting there, and I was wondering if you have any ideas to use it to do anything cool? Like as a mini display for weather/other kinds of data, any of that stuff. I have a 3D printer, so I could easily print a makeshift mount or stand for it to go on my desk, shelf, whatever.
Remember that old phones with no SIM are still able to call 911. You can use them as emergency call boxes.
