I have a design issue with creating a NOR gate. I have a sticky piston facing upwards and a block immediately to the side and one unit above it with a stone pressure plate on top of it. About 6 or 7 blocks away, I have another iron pressure plate.
I want both the pressure plates to be inputs to a NOR gate whose output is routed to the sticky piston. If one of the plates is pressed, the sticky piston should retract.
The problem I'm currently having is that when the stone pressure plate is pushed, the redstone current immediately resulting from that is being routed to the sticky piston, keeping it extended. Any suggestions would be much appreciated.
