For some time I have wanted a more accurate antenna elevation measurement 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?
