This is one of the coolest party tricks ever. One enterprising party host built and set up FaceBooth, a DIY one touch Facebook posting photo booth. Just stand in front of the camera, press the button, and it snaps your picture and uploads it to Facebook automatically. Here’s what the full setup looks like:
He used a program called DSLRBooth to post the photos, made the wood box himself, and wired the button to an Arduino via a protoboard with additional output to his TV. The result is a party-proof photo booth where guests can take their own photo no matter what sort of altered state they are in (more eggnog!!!!) Nice project.
