Weekend Project: Stun Gun Potato Cannon
Launch potato projectiles 200+ yards with this stun-gun triggered, high-powered potato cannon with see-thru action.
Well, this clearly qualifies for artillery of the week. This three barrel potato gun uses electronic injectors to deliver propane to each of its three champers, ignition coils and spark plugs for ignition, and the entire unit, including pan and tilt control is controlled through PIC micro controllers by a gaming joystick.This spud cannon has a 110 mm barrel and a 200mm chamber.
