placing them on separate regulators<<

When I was in college I designed and built a 16 bit CPU (130 chips wire
wrapped so densely it looked like a birds nest) that was packed with LEDs.
I was going for the look of the minicomputers of the time, with rows of data,
address and status LEDs. My memory of electronics is kind of rusty now, but
I think I strobed them with a 555 timer which reduces the current your device
will draw. And by varying the pulse width using a pot, it also acts as a
dimmer control.
