Panasonic and others offer a single or 3 axis accelerometer for Wi game controllers. They provide outputs in analog, or digital. Sts and others also have these with only digital outputs. The Single axis unit is 0.2 " square by 0.1 " high runs on 5 VDC.

system. Shaft encoders are beyond my budget. Do mice still have balls?
Once upon a time every old mouse had two optical shaft-encoders built right in. And mice can detect very tiny movements, so the sensors/encoders must be fairly precise. Nowadays, most mice are optical or 'laser', but apparently, some mice are still available with balls.
So, who is going to take a mouse apart and use the bits to sense AZ/AL angles on an antenna array?
