Since I'm no electrician, I was wondering if someone could help me find a 5+ volt connection on an older PSX. I was going to load the thing with LEDs. Please hold the nasty comments - it's for an art project. Edit: 3.3 would be fine, too. As long as I can put a few LEDs on it without screwing up my Playstation, I'll be happy.
I'd take a look at where the Power LED comes from, and tap onto that. Can't say I've ever modded or dismantled a PSX however
