Re: pic: Off-Season Kicker Design

[quote=rahilm;968133]We're planning on putting a potentiometer on the shaft for the kicker

I would recommend not using a potentiometer. We tried using a potentiometer for sensing the position of our surgical tubing powered kicker. It lasted for about 20 kicks before the acceleration of the shaft twisting the potentiometer wiper caused it to fail. We replaced the potentiometer with an encoder which has lasted two regionals (well into the eliminations of both), and 3 or 4 demonstration/exhibition showings.
