This is an Air Cannon that I installed a motion sensing array and motor system onto.

It scans back and forth at a 45 degree angle much like a security camera, when motion is detected it fires a ping pong ball (or other loaded item).

It is in research because I would like it to be able to fire repeatedly and not just once!! I'm also looking into giving it the ability to stream video and take pictures.

A pet project as of now, I will make it available for purchase someday in the future. Be patient!! =)
