Doh! I'm sorry, <I'm an idiot> indeed.

You mean that the LM317 constant current driver is legendary?

Oh. I didn't know they didn't all have optical feedback. Several other pages and datasheets make a big deal about the power output varying with temperature. this article is pretty informative, especially the circuit diagram... electronicdesign<dot>com/Articles/Index.cfm?AD=1&ArticleID=6316...

Agreed. But... Laser diodes have built in photodiodes. They aren't meant to be operated at constant current, instead they use the photodiode as feedback to get constant power output. I had forgotten that when I wrote my previous post. Anyway, you should be able to mix an analog signal from a...

No promises but what voltages and current ranges would you like for each LED. And/OR post some links to laser diode data sheets and I will think about it. Are you driving the LED's yourself or letting the driver board regulate the current (power)?

First off, hat's off to you ROG8811!!!!!!! Simply beautiful, completely pro job. Brought me and a few friends to LPF. I just ordered a broken PS3 drive from eBay and can't wait to get it. The loading mechanism is broken, I hope the blue ray LED is working. The optics on the sled will be nice in...
