Re: How to Modify 5mw Leadlight Green Laser upto 4

Just wondering, what's the most mW someone has ever gotten out of a Leadlight with a pot mod?
 
Re: How to Modify 5mw Leadlight Green Laser upto 4

Is it true that people have gotten up to 25mW by doing so?
 
Re: How to Modify 5mw Leadlight Green Laser upto 4

Most I've got with a pot mod alone on Leadlight 105 is 55-60mw.

/ubbthreads/images/graemlins/smile.gif Sounds pretty good, hope I can get my 105 to 15-20mW with a pot mod... when it comes /ubbthreads/images/graemlins/smile.gif

Re: How to Modify 5mw Leadlight Green Laser upto 4

Just done my pot mod! Still shaking and sweating from working on my precious greenie, but wooooo - is it bright!
 
Re: How to Modify 5mw Leadlight Green Laser upto 4

Just did the stage 1 mod and used a 3/64" flathead screwdriver to turn the pot. I could make it much dimmer but not much brighter. I measured using the green LED method described earlier at about 6mW. I felt hard limits in either direction for the POT. Is this the case? I don't want to turn it too much/hard and break it off.

edit: used a more accurate multi-meter and measured 11-14 mW. Very nice beam is visible in non sunlight, bright light. Thanks for the instructions.
 
Re: How to Modify 5mw Leadlight Green Laser upto 4

I just bought a laser from abeland1 and told him I was from CPF so he sent me a higher powered laser. There was a post it note on the box that said "23.6 G", but I can't tell if its a uppercase G or a lowercase "a". My friend says that means its a 23 mW laser, is this right? If that is right, would a pot mod make it even brighter?

This is the first green laser I have ever seen too, so I have nothing to compare it to.

The post-it note is the reading from my Coherent Lasercheck after one full minute of operation. Please do not try to modify it by increasing the input current to the pump diode. This is just as likely to decrease the final power output as it would be to increase it. The "G" means simply that it has Gold colored trim.. Try to find someone with a a pointer form another source and compare the performance against theirs and your mind will then be at rest.

Re: How to Modify 5mw Leadlight Green Laser upto 4

Wow! I successfully completed both mods and am very pleased.

I have ran into a small problem however. The beam is no longer centered on the focusing lens. I have disassembled (unscrewed), and reassembled the lens several times, thinking perhaps it wasn't on properly. Nothing I do seems to resolve the problem.

The beam is way off-center (almost touching the metal edge). I cannot put the front aperture cap back on, as it practically blocks the beam.

Any ideas on what may have caused this? Thanks in advance.
 
Hi all, im new to the board. I ordered a leadlight from vital spirit and just recieved it today. (yay)It was already impressively bright. I think brighter than my old GLV5 greenie I had. Anyway I wasted no time and opened it up, did the pot mod which made it conciderably brighter. Then I unsoldered the diode from the board and losened the locking ring and twisted the diode around looking for where the brightest spot would be but it never gets any brighter so it seems that my pointer isnt responding to stage 2 at all which is a shame and disappointment. Im guessing the crystals are just not a good set. Im not sure what mw its running because I dont have a multimeter. Anyone know any other reason it could not be responding to stage 2 of modifying a leadlight?
 
Why didn't you first guess that your laser had already good alignment. Mine had too. And this is far from a "shame" /ubbthreads/images/graemlins/wink.gif.The quality pointers have their diodes already fine aligned. The stage 2 is not "modifying" but more likely - fine tunning. So, only badly build units will respond positively to the stage 2.
 
lol, how bout this one then.
i did the pot mod. saw a big difference in brightness (for less than a minute), put it all back in the case only to have snapped the white button off. i gave it to my friend to fix since he has a soldering iron. looks like he did a good job, not messy and the button is on well. but.... it doesnt work. he has offered to buy me a new one. but i wanna try to fix this, i feel like im just wasting it.

what can be done to fix it?
im going to buy another its just its eating at me cuz it seems like an easy fix and it was only the button that snapped off.

thanks guys
 
Kudos to everyone involved in helping the dummies like me figure out how to modify these lasers! Within minutes of receiving my 105, I had performed the seemingly miraculous improvment of step one. Wow!! But, the gadget-geek side of me couldn't rest until I tried step 2. That's where I should have left well enough alone.

After performing the re-alignment process, the reassembled light seemed slightly dimmer. I thought perhaps I had bumped the pot, knocking it down a notch or two. So, I tried to re-adjust it. Having gained some confidence by those that has posted the ultimately bright lasers by shorting the pot to the case - well, I tried that.

Without so much as a pulse of light, it went dark. It was just a momentary short - not even an 1/8th of a second. It did something. Something bad.

Now, when I look into the front of the assembled laser, I see a very, very dim red dot. When adjusting the pot to every possible position, I'm able to spark an ever-so-faint green dot. The pot still works, but the range is from off, to red dot (internally), to extremely faint green light.

I went back and resoldered everything - thinking perhaps a marginal solder point couldn't handle the over-current of the shorted pot, but that didn't make a difference. I've tried re-shorting the pot, but it just turns off the laser all together.

Has anyone been able to revive this? I went ahead and ordered a replacement, but I didn't just want to throw this away with out trying other things.

I'm bummed, but I knew going into it that I would probably break it. It was a risk I was willing to take - and I don't regret trying it...
 
very sad day indeed, i know what you feel like. from the sound of it, your Diode is dead. and there's definately nothing you can do about that. sorry about the loss

I too broke a laser trying to do the stage 2 mod, but it was because of my marginal soldering skills/ very cheap soldering gun. In hindsight, I shouldn't have tried the stage 2 mod at all, because the laser was already very bright after the pot mod, but as erkme73 said, my inner geek got the better of me.

I did the mod and had it working after resoldering (although I don't think I actually got it any brighter), but the circuit board must have been slightly off center, because the diode/ circuit board assembly was too tight to fit all the way back in the pointer housing.

When I tried to take it back out, two of the contacts between the circuit board and the diode pulled out of the diode. There's no way I will be able to fix it. When I get a new one, I'm going to forego the stage 2 mod.

So, the moral of the story is "leave well enough alone, unless you really know what you're doing."

P.S. If anyone thinks they could fix my broken laser, I'd be willing to sell it pretty cheap. Otherwise, I'll just keep it as interesting junk.

Has anyone heard of the Leadlight laser from Z-Bolt (BTG 6 Plus)? If so, can you tell me if it is the Leadlight 105 or 110? I can't tell and am thinking of purchasing one.

Thanks...
