I recently converted a discarded waterfall / nature sound machine into an automatic photographer for use at parties, which I have dubbed the Smilebox. The project was an exercise in salvage as I was able to find almost all the materials in piles of discarded E-Waste.
Similar to larger photobooths, the participants pose in front of a camera and initiate a countdown sequence by pressing a button. So far the unit is entirely self contained and battery powered since all the pictures are stored on the camera for later processing. In the future it would be nice to add an uploading feature so that the pictures are automatically transferred to a photo sharing site such as Flickr or Google Picasa.
