It takes lots of work to mod the Xbox 360 to act like a Wiimote. The accelerometer works by outputting varying voltages for varying accelerations. I will use a 3-axis accelerometer so it will output 3 varying voltages. I will use an analog-to-digital converter to get the signals into a micro controller. The micro controller will do the processing that determines how the controller is tilted. It will then be output as an analog voltage to the controller in place of the on board potentiometers that are controlled by the analog stick. Analog sticks work by adjusting two potentiometers (pots). After I took the controller all apart and experimented I found the potentiometers had an upper voltage of 1.61 volts and a lower voltage of 0 volts. On the up/down pot all the way up is 1.61 volts and all the way down is 0 volts. On the left/right pot all the way right is 0 volts and all the way left is 1.61 volts.”

This is awsome, totally custom design and setup, love it. I personally have no use for a motion sensitive controller, but I love the idea and build ambition. Keep modding, I’m loving these 360 mods - people are doing button duplication and relocation as well as LED mods on the http://www.llama.com forums, I’ve done some LED mods to a wireless 360 controller myself here in the hackedgadgets forums.
Keep up the good work!
