Laser out of a CD player

Unexpected image from a laser extracted from a CD player shown on a sheet of white paper. The infrared energy is visible only with a black & white video camera or video camera with night-shot capability. The focusing coil is controlled by a joystick interfaced through a bank of transistors.

Latest Air Cannon

This is our latest air cannon sized for tennis balls. The design has two electromechanical valves to maximize the rate of air pressure release.

Air Cannon with two tennis balls

A short video with sound of the new air cannon in action. The object that falls off to the left is a Gatorade bottle used as packing as it fits perfectly inside the PVC barrel. The two tennis balls are loaded after the bottle and some water is added to increase pressure seal and provide some smokey aesthetics. Note the tennis balls simply dissapear into the sky; excellent performance, difficult to find the tennis balls when they land.
