- by - in Zany

The gun can either run off an Arduino board, or you can buy a custom made board from Rudolphlabs. It can be made to fire airsoft (Nerf) bullets if you don’t want to risk shooting someone in the eye with a paintball. It uses simple servo motors to aim and fire the gun, and a webcam for tracking targets. A microcontroller is hooked up between the gun and a computer to control the servos.

It’s a completely open-source project, and is even used by the Australian Navy for training exercises!

You can find all the instructions, code and schematics on the project site.
