My 2c is that John needs to make the light flash in unison with the 1st and 2nd player lights... "anything less would be uncivilized."

Yeah that is what i was saying to do  . The only thing is, I wouldn't use the IRF510. Let me find one real quick |

Okay nevermind on the IRF510. I was going to try to pick out a better FET but i realized that was a huge waste of time for how little current you are going to use. Ill scan something real quick

well the thing in the middle is the IRF510. I didnt draw it schematic like that one you should understand. The arrow thing is the LED.

So.... 5v goes direct to the led and then the other led lead to the MOSFET? Then one leg of MOSFET to ground? The other to pulsing 5v? |

yep.
Just curious... That doesn't match what the other guy said. Does it? |

No it doesn't match. You wouldn't be able to turn on the mosfet if you attach the source to the LED. Its a bit complicated so I'll spare you that. But the gist is, N-type fet's (IRF510) have to be on the low side of the load, P-type's have to be on the high side (as described by the other poster)

Cool! Thanks. Looks like radioshack has the MOSFET. I'll grab one.

Ok, I stopped at Radio Shack on the way home from work and grabbed a MOSFET.
And....
IT WORKS!!
Couple of things:
#1 - I cannot use the non-ghosting LEDs. If I do, the roller light goes OFF when I start the game. The voltage must be dropping below 4V.
#2 - The roller flashes the exact OPPOSITE way the 1p+2p cone buttons do. Not horrible, I can live with it.
#3 - During the attract mode the roller pulses from DIM to BRIGHT, DIM to BRIGHT. It's never 100% off. It still looks cool. However, when I start the game it goes to 100% lit but DIM. Still looks good.
Ian, what do you think of all this?
