So, who is going to take a mouse apart and use the bits to sense AZ/AL angles on an antenna array?
I have a sacrificed recently a roller-ball mouse from aopen to my az-el rotor system project...
I'm not decided yet for shaft vs. gray encoders... (gray encoders are almost winning... !!!)
6 bits gray encoders give 64 positions in 360 that's aprox 5 degrees steps... pretty good...
7 bits will be 2,8 degrees steps...
UTP cable is almost inexpensive.... has 8 wires ... hum... ground + 7 bits... interesting... parallel port of a PC as the input/output device... software will be written in python... (put your favorite prog. lang. here)
