Here’s a rather very interesting DIY project that involves a marble maze controlled by a wireless accelerometer housed in a Wii Steering Wheel unit. Brilliant!
I purchased the Wii steering wheel unaware that an additional button is mounted to the back for the “B” controller input. At first I considered removing this button to prevent users from getting confused but decided to utilize it instead. During testing I found it awkward and difficult to hand off the controller or put it down without the maze going crazy as it continued to follow the accelerometer’s measurements. I decided that a “dead-mans” switch would be a useful addition so that the maze would only accept input when the button is held down. This allowed the controller to be handled without causing the maze to move unless desired.
