so is this for dual shock only? i hooked up the led and the most i could get out of it was a blink every now and then (about 30sec) w/o the resistor.
i would hook up a transistor straight to the battery but there isn't enough voltage.
i made sure that the 3 points work with 1 3mm led hooked up (they will probably be fine with more, i will post when i find out), i suggest you use tp11 or tp12 since the R4 point is very week and comes off the board easily.
i didn't test tp11 but tp12 works fine with 5 leds.
