Quoted from DumbRecords:My big question is, I haven't researched the schematics for black hole, but I thought it would be cool if I could hook up some led strips that would be mounted to the curtain around the machine to create a lighted tunnel effect when the relay activates for the lower playfield lighting.
There are 28 volts lamps under the play field around the plexy lens. Connect a relay to the lamp wires. Run your fan on one set of contacts and the led strips on the other set.
