Let see who is the most creative:nanner2:
Took the stock plastic piece, cut a rectangle out. Designed a pulse width modulation circuit which is variable based on the value of a potentiometer. servos have three wires, PWM, power, and ground. I anchored a hobby servo to the underside of the stationary part of the dash panel, and several linkages to the hinged panel. The gauge pod face you see is made of wood, with some filler and lots of primer/sand repititions.The servo runs on 5vDC so rather than make my own voltage regulator, I ordered a plug-in cigarette lighter one for cheaper than the prototype board i'd have built it on (nevermind components)That is cool. Please explain how you did it.
