And industrial/water proof version of these! :)

Some Circuits related to using these mouse optical encoders for other
purposes... such as robot positioning! :) David you'll like some of this
info :) 


http://hackaday.com/2005/06/09/quadrature-optical-encoder-built-from-a-m
ouse/ - This one can measure direction of rotation as well as how much
it has moved! Perfect for the rudder position application!!!

Also if your going digital for sensors of any sort... Have a look into
Arduino Microcontrollers! They have pressure sensors, temperature
sensors, humidity sensors, and you can even hookup a GPS receiver and
Bluetooth interface etc, I'm currently designing an autonomous boat (for
research and water quality testing purposes) and im thinking about using
the arduino + GPS as the whole navigation setup for the boat...

** what is the solution to waterproofing the potentiometer?

You better ask Alan about the underwater use of potentiometers, and how
to
waterproof them. Personally, I hope to find a way around it by using an
inductive device, that I hope will lend itself perfectly to epoxy
potting.

Best regards,
