Voice Over IP slot car racing!

Voice Over IP slot car racing? Come again? Apparently, this project takes advantage of Asterisk to take in the phone data and spit that out to a Java based softphone. This softphone takes in a SIP stream and then measures the waveform amplitude data (volume). The louder you speak, the faster your VoIP-enabled slot car goes. Just don't take a breath or pause or your slot car will stop. The amplitude data is sent serially down to an Arduino board.

I remember playing slot cars in a friend's garage, which was a lot of fun. Somehow the thought of screaming into a phone to make your slot car go faster might get a little old after awhile. Still, might be fun. Pretty amazing what fun and interesting projects you can do with open source Asterisk!
