Air Cannon

[Michael223]

I am working on building my own Air Cannon. I want to be able to fire multiple shots (of T-shirts), in a short period of time so recharging the cannon between shots needs to be done by either a CO2 tank like on a paintball gun or any other suggestions you might have. Does anyone know where any good Air Cannon designs are on the web? The ones I have found all need to be recharged between shots with either a bicycle pump or an air compressor. The idea is to be able to mount one of these on our old robot and create a promotional bot for high school football and basketball games to shoot our T-Shirts into the stands like they do at professional baseball games and other events. The simpler the solution the better. I am also working on designing a way to auto reload the cannon between shots. Thanks for the help!
