how many amps can that power supply provide?
do you have any technical documentation on the LED's?
how many transistors do you have?
do you have spare "raw" wire laying around (heck at the currents we are talking about a old floppy disk or IDE cable is more than enough to scrap for wire)
do you have resistors?
whats your budget, do you want to spend more, or do you want to wire more crap up, keep in mind spending more is within a 10$ range, so whats your time worth to you?
and its no problem, I herd up electrical engineers for a living, I can handle a new guy wanting to get something done, EE's are scatterbrained on good days and they know what they are doing lol
