Finally got it to work. I played it safe with 10 ohm resister. it still burns and fits nicely!!!

WOW! 10 ohm resistor will get you about 120ma. that's a really weak laser considering. I use a 3.3 ohm resistor to get me roughly 300ma and a 5ohm resistor to get me about 250ma. Now these #'s are ballpark as the driver on the dorcy puts out different current in each flashlight. You really need to use a dead laser diode (led'd) to test the current on each and every one of these things!

Unfortunately, I have no more dead diodes. After an LD dies, I hit it with a butane torch.
I didn't want to burn out my last diode so I put a 10ohm. Radioshack doesn't give me exactly what I wanted.

yeah with the radio shack resistors I ended up using 4 in parallel to get the desired current. that or two. both are good. So now you know. Keep those dead diodes handy. they do serve a purpose after death.

but its fun to melt them too! lol

I'm gong to cut a heat sink and fit it into the head with the laser module through it.

I've been afraid to push it to 250 let alone 300 ma Ken. Is 250 your CW operating current now on your production lasers and how long have you been able to keep them lit? I finally got a decent digital multimeter thinking that my old analog workhorse was off and it does indeed confirm I'm only pushing this thing to 200 ma with the 3.8 ohm resistor and cap. I thought I finally had it nailed before that LD with the strange projected pattern abruptly died. I've got to rule out voltage and current and even heat as the killers. The only thing I can think of is that it was defective and self destructed. Boy am I having bad luck with these. For what I've invested, I could have purchased one of yours but I really want to accomplish this myself. Is there anything you can think of that I missed before I try again?
Also, where are you getting your warning labels? Thanks!

I honestly don't know what to tell ya conserning the problems you've been having. I'm running my production one's at 300ma but I'm also using my heatsinks.

Ken:
As you are using pretty much exactly the same electronic configuration as I am And successfully driving yours much harder than mine. I have to assume it was a bad diode and try again. I know what happened to the previous LD's, it's just the last one that had me perplexed. I'm also using that massive aluminum heatsink so that can't be it either. SenKat is sending me another diode so I'll give it another try.

try the method I'm using now of the plastic base and put a peice of plastic between the legs of the diode. I've had to replace 2 diodes from lasers because the pins shorted together. that might have been a problem.

I just made my first Dorcy and would like one also. If they aren't for sale I understand. Could you post the dimensions please?

also, another question, for the actual diode, does it matter if its an open can or not, do they use the same axis housing?

You can use an open can or a closed can as long as the diode is the smaller 6.5mm

Phazonx I could only find a 10 Ohm resistor and mounted that in, but it doesn't even light a match Where is everyone getting their 5 Ohm and 2.5 Ohm resistors? I can't find any shop or anything online for up here in Canada. I checked out Digikey, but they are out. Is it the 1/4 watt 5 Ohm resistor?

Kenom, are you not putting in the cap anymore? I noticed in some of you previous posts, you use 4x10 Ohms resistors and 2x10 Ohm resistors. What should I be doing?

Thanks for your help guys


Cheers
