[TowerTalk] Prop Pitch Power Supply and Control Circuit

[john at kk9a.com]

Green Heron Engineering makes a nice prop pitch controller that provides 25 
to 28 volts for the motor and it uses a pulse feedback for direction 
control.

I am in need of a schematic for providing an adjustable 24VDC for a small
prop pitch.  Also need a circuit for controlling the direction other than
selsyn motors.  I understand that some people have used a Hall effect device
and a magnet mounted on the PP motor shaft.
