Your graphing calculator may not be getting much use these days now that other mobile devices can do the job, but it still has a few tricks up its sleeve if you're willing to do some tinkering. Christopher Mitchell's latest project, ArTICam, lets you turn a TI-83 Plus or TI-84 Plus calculator into a selfie-oriented camera. The mod mostly requires a Game Boy Camera and a programmable Arduino board like the Uno. After a little bit of wiring and some (thankfully ready-made) code, you can snap self-portraits with a calculator command. The 128 x 123 grayscale pictures you take won't win photography awards, but that's not the point -- this is more about having fun with gadgets that might otherwise sit in the closet gathering dust. Hit the source link if you have the gear and want to give ArTICam a whirl.
