During an ITP Camp session run by the folks from littleBits, one pair of campers designed and made this fantastic sound-triggered bubble maker. Toshitaka Amaoka and Chris Mansfield made it using a fan, a 9 volt battery, some wood, a plastic cup, and the upcoming sound trigger module from littleBits. Not only did they design and make this fun project in under two hours, but the documentation for their project is already posted to the littleBits community site. Now that’s what I call rapid prototyping!
Don’t Blow Bubbles, Clap Them
