We have done this with an array of relays for the last two years and had no problems with inspection. I havn't read the rules carefully enough to see if it is legal this year though.

It Looks to me like Rule R51 prohibits this sort of thing. There may be a loophole however. I believe that all the jumper does is pull a pin either high or low. there is no rule that i can see that prevents you from directly connecting this pin to a digital output. I wouldn't consider this a "custom circuit". This may be a loophole but i feel it does not go against the spirit of any rules. You are not providing a PWM outpur, not directly controlling movement and not posing a safety rist. BTW I believe the signal pin is the middle one.
...I tried to pump it up to the 47 inches. I stopped around 42 inches, than tried getting it through a 36" door. It got stuck, I proceeded to dropkick the thing in front of my team and a girl I had gone out with the previous Fri. It didn't move, I hit the floor.
Ouch, my pride. - ChrisMcK2186 [more]
