Ok, does anyone know if perhaps there is a 6 volt power lead from the power supply? if not is there a way that i can convert a 12 volt molex to 6 volt somehow?
No there isn't one. 5v could possibly be close enough for your needs. I'd look for something like a cigarette lighter power adaptor and then wire that to a 12v molex lead.
I agree with the above poster, use a voltage regulator since depending on how much you are drawing, a resistor's rating may not be enough. Use either a variable voltage regulator or the 7806 set voltage regulator.
Thanx fer the suggestion gang and you were right firehed 5v was enough. it turns out 5v is actually 5.16v and i guess that was enough to run it....it was a plasma ball btw . maybe ill actually post this mod, maybe a work log too....
