[simpits-tech] 360' potentiometer?

[Marv De Beque]

Interesting device, but it is only 340 degrees (+/- 10 degrees) rotation
electrically.

Mechanically it can rotate endlessly, but will have a 20 degree dead spot
each revolution.

Maybe you can use two of them and offset them.  A micro could interpolate
the actual rotation.
