Quoted from lyonsden:Hope this is useful to some people. Next up on my list are building a backbox LED and flasher kit for a Stern whitestar (LOTR) and perhaps an under cabinet flash kit. The under cab kits are neat and I am all for excessive pinball LED bling, but I don't think it will work out well for where I have my machines.
In any case, the parts are ordered, but take a while to arrive (LED strips are coming from China).
There is one thing I'd like to figure out, but haven't dug into yet: How to add an interrupt for the backbox LEDs that turns them off when the game's GI turns off (nice lighting effect). If someone has already figure it out, please pass it along.
Maybe a relay in the GI circuit in the backbox that you wire the orange positive flasher wire through. So when the GI is on the relay is switched to allow flashers to get power. Then when GI is off the relay turns off and cuts power to the backbox flashers. ??
