Aquarium webcam
I’m headed out of town for a bit and I’d like to keep an eye on my tank. Luckily linux has software that can do that called motion (obtained via apt-get install motion). You can do all sorts of things with it like time lapse photography, stream at whatever fps you like, auto adjust brightness, etc etc. Had to remove the filter from my ps3eye so a little too much IR is showing through, but it should be sufficient to make sure everything isn’t dying, here’s a live picture (refresh to get a new one):
