Propane-powered Potato Gun

gf spud gun.jpgThanks to Design News for this Gadget Freak, featuring a tripple-barreled spud gun, charged with propane! Someone has had their chips.

Two PIC microcontrollers handle the User Interface, Azimuth and Elevation Aiming and Fire Control functions. Aiming is controlled with a joystick.

The Fire Control subsystem verifies a projectile is loaded in the selected barrel before injecting the controlled charge of fuel and that the barrel is armed before firing.

Remember, the system doesn't verify the operator's age, sobriety or aim - that's your responsibility! Take care out there - those potatoes are live.
