Modular DIY Photobooth

For my wedding in October 2011 I asked my fiance if I could build something, she only asked that it not be tacky. This is what I came up with. It's a modular folding photo booth. I designed the model in Sketchup, programmed it in Autoit, and gave it a nice Glados voice. I needed an input device and I decided to make a serial comm button. I took a 555 timer and made it generate a 4.8kHz square wave. At 9600 baud this translates to UUUUUUUU plus one garbage character when the button is released. f
