Unlike standard spud guns, “the PIC controller allows for lots of safety features such as only allowing a single charge of fuel and ensuring that there is a projectile in place before fuel can be introduced.” Video after the jump.

This project is definitely not small potatoes — three barrels loaded with spuds and charged with propane! 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
