Part of this video that we featured a short time ago was this Hand Held Self Contained Air Cannon. Now we can see some close up pictures and a detailed description of how it was made. What will come out of the FastMHz crazy high voltage lab next? We will have to wait and see…

“This is a relatively simple device bodged together from junk I had around. Take some PVC parts, an old tire inflator, solenoid, capacitor, inverter and various other stuff.

The design consists of a tire inflator compressor strapped to a PVC air chamber. In the rear the air goes in via the fittings seen below. The air is released from the front via a solenoid…it’s rated 48v…but it won’t trigger with 100psi at 48v, so I rigged up a capacitor to feed it 200v or so for a split second, enough to shoot perfectly. The short duration causes no damage to the coil in the solenoid, but not all may be as rugged as this one - YMWV. This one came from a junk box.”
