This set of PVC cranks make you work for your game of Puzzle Bobble, also known as Bust-a-Move. It uses a little cannon centered at the bottom of the screen to pop bubbles based on like colors. There is a cartoon character that cranks as hard as it can to aim that cannon, and this hack brings that effort into the real world.
The controllers are made from PVC. A bit of creative use of joints and different pipe diameters make for a freely rotating rig. Rotation is monitored via the optical encoder wheel from an old mouse. Above you can also see the plastic container that hosts the ‘fire’ button. Since the mouse is already an input device, there’s no other electronic work to be done. Just plug the controllers in and map the wheel/buttons to the game you want to play. Make sure to check out the demo video embedded after the break.
If Angry Birds is more of what you’re playing these days you should consider building your own slingshot controller.
