Well I want to mod a PlayStation (the original one) but I've never done anything like this before. Which is why I'm practicing on a PS. But anyways I know how to wire leds I just don't know where to hook them up to on a PS! Please describe how to find a location and for how many leds. I know I'll probably need a volt meter... The led I want to add runs on 3 LR44 button cell 1.5V batteries. So what voltage would I need to find on a PS? Also, Is it okay to just add anywhere I find the right voltage or would it divert power away from something important?
