a pot, two pulleys, a belt, and a digital ohm meter... if you are careful about picking the size of the pulleys and the value of the pot you could even get it to read 0-360 without any conversion.

mast already in place and you can't get a pulley on it?  use a waxed string around the mast and pulley with a little spring to keep it tight.

or of course just use an analog meter and write the beam headings on the meter face, then you don't have to worry about the sizes of the pulleys or pot as much.
