yea i looked at it, and i wired it up as the diagram showed on daeduls's pics, but when i read the box, it said pin 2 is Vout instead of Alt[/quote]
Ignore daedal's pin numbering and go by the circuit in the link I provided for you. The rheostat and resistors all need to be connected in series between the adj. and voltage out.

Redo it...I am not so sure your diode is dead... 
It is worth it to find out right???

I'll bet it should work =]
I accidentally put 6v into my 6x DVD LD yesterday by wiring a polarised capacitor on the wrong way round :-[ and yet, it still works
EDIT: That's why daedal's circuit is so good, I had my 50ohm pot all the way up and a 10 ohm resistor in series so the current was too low to fry it...
That or I'm just lucky :

well haha, i couldnt wait and i re did it, but even with the way that was specified, the POT wasnt able to do lower or max the current going thru.... so i had to Re-wire it by putting the positive lead from the battery pack off the lead 1 of the LM371, and soldered it to the POT's pin 1, then on the pot hooked pin 2 and 3, and then soldered a wire there to the lead 1 of the LM371, that let me increase and decrease the current, i checked this with a white led.
but when i hooked up the LD, the diode was actn the same, and i tried to touch the brass part and it was hot within a few second.
oh man.

What pot and resistor are you using, maybe some pictures?

Tried using the other diode?
I had a light JUST like that from the non-burning LD.

Most likely, IR or not is debatable but it is certainly visible and looked like that!
My diode is so cold at the minute... even after a few minutes, I need to double up the 10ohm resistors like you have.

I borrowed a Volt meter from a friend of mine.
When i hooked it up to the battery source directly (4 X AA) it read 5.51v)
when i hoooked it up to the positive and negative leads where the LD should be hooked up to, it reads 4.80v
i dono whats goin on, whats not working? now i know how i killed the diode, too much current to it i guess!

Dawgz - you are getting current and voltage mixed up ! I will post some (Plain English) instructions in a few....We wil get you up and running, for sure !
