would you happen to know where i could get a red burning diode? that i could see the beam or dot, I would rather have one i could see. thx

Thanks for the info, Is he pretty good on quality?

ya the driver is hooked into the pc power supply I did not have anything else to power it with.

what diode can I get for this circuit that would be visible?

OK got a new power supply using from computer 12 v. at min its pulling .179 amps at max its pulling 1.080 amps, I tried the web cam trick and saw a very faint light at max with the diode right up aginst the white paper(the ir rays were not nearly as large as yours, I could barly see mine). I...

Ok thank you for the help ill try to find a different power supply.

I payed about 40 dollars for it on ebay.

Ok i got the rest of the parts and built the circuit to the schematics you sent identical to them except i used the 1117 regulator you said to use. I hooked a 9 volt battery to the diode and turned it on, i kinda leaned over and looked at it on an angle and saw a tiny dim red light but thats all...

Ya iam just trying to get the most power out of the diode and also a long life, or what i can. ya I was thinking about just puting 3 10ohm resistors in parallel like you said, would that still be ok with thw 100 ohm trimmer?

Do you think I could use a 100 ohm trimmer instead of a 50 ohm?

Would you happen to have another wiring diagram or modify the one you sent to me with the 470 ohm resistor and capasitor, sorry i do better looking at the wiring diagram then trying myself. lol thx

Ok I got the stuff kinda but the electrolytic capacitors are 35v instead of 16v will that work? also I could not get ahold of a 3.3 ohm resistior to save my life. but i got everything else i guess. what else could i use to replace that 3.3 ohm resistor?

Thank you for the help, I will let you know what happens when I get the components.

Hmm looks like iam going to have to get more parts, so did I blow up my diode then? I mean in the diode function on the dmm it still reads like a normal diode. Ya I thought that schematic might have been messed up my diode only had 2 legs.

I built another driver and the still nothing but this one the regulator actually get hot and iam getting .789 amps out of, http://3.bp.blogspot.com/_4wHo2MPDwAc/R2YuBFTq09I/AAAAAAAAAAU/4FCiHm71rQE/s1600-h/Driver.jpg that is the electrical schematic I followed but I only used 1 4 ohm resistor...

Do you use yahoo messanger or aim? this might be easer to be walked through, I opened the ground on my diode and put my dmm in series measuring amps and the circuit is pulling .012 amps

Ok with the diode wired the correct way iam measuring voltage at the diode legs (with everything wired up) I read 1.415 volts with a 9 volt battery. now with thw diode unplugged, at the output wires Iam reading 8.59 volts. And both ways my voltage regulator is cold to touch (also diode when...

the diode still reads 1.179 one way and OL the other way, Iam not sure about laser diodes but on a normal diode thats good. So what to try now? On the back of the diode I see one leg looks like it is just part of the diode housing and the other has a black ring around it and goes into the diode...

I tried reversing the polarity on the diode, still nothing.

No nothing happens, no light or anything even with the 9 v.
