I have a couple of prototype angle sensors looking for a good home.
http://www.brickshelf.com/gallery/johnbarnes/Sensors/thumb/rotation.jpg_thumb.jpg
These simple devices contain a potentiometer and a small series resistor so
they vary from 1k - 11k while the input shaft is rotated through approx. 270
degrees. There is a built in slipping clutch, so the device will not be
destroyed if the input shaft is inadvertently over-rotated.
The primary intended use for this sensor is as a feedback element in a
control loop - a motor output is used to drive a mechanism which is
monitored by the sensor which feeds back the current angle via a passive/raw
input port. The RCX code is thus able to "servo" the mechanism to specific
position.
If you want one, please email me describing briefly the intended application.
