The right eddy sensor board (WMS #A-16922, Prox Sensor II PCB Assembly) on my ST:TNG has crapped out. It always thinks a ball is present and trimming the pot doesn’t help.
Rather than spend any time trouble-shooting the board, I’ve decided to use this as an excuse to fab a circuit board, order parts, and assemble it. I’ve been doing a bunch of electronics stuff at work and I’m just itching to make a board for the pinball machines (even if it is a trivially simple one).
