Accelerometer Mouse

Bernard shows us how to use an use an accelerometer as a mouse. This project uses a MEMS X/Y accelerometer, a PIC microcontroller and a old mouse. He also describes a trick for powering the new mouse with the unused RS232 serial control lines.

This is a great idea. My optical mouse is always goofing up on my desk’s wood grain and traditional ball mice, well… they suck. Word has it that Apple’s next Mighty Mouse is going to be accelerometer based. Why wait when you could build your own?
