Quoted from Pac-Fan:
You don't have to remove the resistor to go back to normal incandescent. The lamps work fine with it still in place as they have lower resistance than the resistor.
Yep, as I stated at the bottom of my message
Wow.. Okay, 7 sets (each game would require 3x mini boards to interface with the connectors/harness) of boards would probably cover my first PCB fab run. I haven't priced things out, but a friend who does a lot of fab-ing for some battery charger projects thought there would be no problem in doing this for about $30 for a set of boards (PCB fab, installed components soldered in, testing). Is that within a reasonable range -- $30 per game?
Yep, count me in also.
