thecapacity] sent us his iobridge project where he controls a coil gun with a Wiimote. To make the coil gun, he took apart an office golf putter that had a ball return. The mechanism to return the ball is a metal cylinder that is moved magnetically. He simply replaced the cylinder with a smaller diameter piece of metal to create the gun. His computer monitors the Wiimote axis changes and sends them to the ioBridge. The unit could be located anywhere, but without a camera on it, he’ll have a hard time aiming. There’s a video of it working after the break.
