Amperage Fail... On yellow LED string 3 -- dimming.
$35 later this be the upgrade.
IC is K847PH (4 in one fun), Inputs 1 to 3 in series from HDD header on mobo (pin 1 with blue wire). Collectors in parallel. Lovely "negative" terminal layout.
Problem solved though though I am having a "sad"
This is Definately Sparta...

It is a modification to a computer case to increase the number of "hard drive activity" LEDs. I call it "The Heart of Koios" for the obvious related effect.

Basically one single-channel optoisolator wasnt enough to push the 45mA of current to all of the LEDs I wanted. One of my strings dimmed below reasonability (due to current division) as I should have realized it before I soldered it up.
So I had to redo all this wiring (thankfully not glued like it is now) http://www.furaffinity.net/view/10990425/ and put in a "4 banger"
(aka Quad Channel Optoisolator with 1 channel per string or 'loop' - see the PDF)
