ProjectExciteBike is a mod that turns your exercise bike into a controller for the Xbox 360. This model will receive pedal input from the cranks of the exercise bike, where a ring of five hall effect sensors will be able to detect a passing magnet that is attached to the crank. Such sensor data is then collected and processed by an Arduino which in turn is hooked up to a wireless Xbox 360 controller for output. While you won’t see professional gamers adopt such a setup anytime soon, who says you can’t lose weight while playing the Xbox 360 when compared to the Nintendo Wii?
