Interest guage - 200mw 660nm red pointers...

Ok, it was a long wooden safety match, red tip, and I sharpied it. I just ran the test again and it lit in less than 1 second.

Just for note, I had to turn the lens out 1 turn from how it was originally focused. This placed the focus about 10 inches out from the front of the laser. At 10 feet, the beam diverges to about 1.5 inches.

Thanks for that Tom. I have a do it yourself red laser and it will light an unsharpied match, like the match you were using, at up to 4 feet away. But it has to be perfectly focused. I don't have a power meter yet, but since I am supplying 240ma of current to the diode, I know it is putting out well over 100mw of power. Of course the lens itself has a lot to do with burning too. I think with a bit of tinkering, you might be able to get the match to light without having to sharpie it.
 
Sounds like a fairly easy fix if not too many of the threads are damaged. Eagerly awaiting for mine to arrive. :)

I'll see if I can post a picture sometime today if I have some time. But I see the main problem. Take a look at the first post that greg made. The front of the laser is metal. Then there is a short plastic segment that has a threaded portion that screws into the alum. battery barrel. To make the positive connection to the battery section, there is a small brass washer with the positive wire soldered to it. When assembled, the spring makes contact to the neg battery contact and the brass washer contacts the positive battery case.

It seems that the washer on the broken unit is about three times thicker then the unit in Greg's picture, thus limiting the amout of threads for the mating of the parts. So when the unit was damaged in shipping, it just pulled the threaded part out, stripping the last thread in the plastic part.

Other than that, it looks to be a well made unit. If I can get a thinner washer, I think it will go back together just fine.

Now, I am waiting to see if anyone else opens their laser up to see if I can get to the current regulator.

On another note, my two laser diodes arrived today. Again,  a big thank you to Greg.


Regards,
Tom

I received my "Broken Laser" yesterday. Here is my review. Take it for what it’s worth.
Condition: in the electrostatic bag (opened to test from Greg I presume). The laser was in two halves as Greg said he received them. Upon my personal inspection here is what I found out. There is a brass ring that goes around the end of the battery tube where the laser head screws in. The brass ring was 2-3 times thicker than it should have been. This means that there was all of one or two REALLY tiny threads holding the metal battery tube on. . . . that’s where the laser broke. When looking in the battery tube and on the laser head where the threads are I could see left over residue from GLUE. It looks as though they tried to Glue this area together, and the glue had no chance getting through shipping together… I cleaned the glue off of the metal battery tube with a wire brush tip on my dremel, and then used a Nylon brush tip on the laser head threads being It’s made of plastic so it’s non conductive. I then proceeded to grind down the brass ring that conducts the power to the laser. It’s about 1/3 the size it used to be and now leaves plenty of threads free to grab onto the battery holding tube. Then I popped some CR123a batts in and turned her on, BOOM nice bright red goodness coming out the end. Quite a fat beam, too fat to light matches without culminating it. I grabbed a plastic screwdriver and tuned the beam to around 17in from the laser. I was able to burn through trash bags with ease, black anything instantly starts smoking and a sharpie match lights almost instantly. I will be taking pics and vids later and will post them up on my google pages to view.

In an Mr Burns voice, "Excellent"! Looking forward to the pics (HiRes?? :))

"Hires?"

Well, I'll be using my 12 mega pixel Sony, but I'll be shrinking them down for online.

That sounds like a steal!! $75 for such a red laser is really one hell of a bargain... If I had the money I would have most definitely gone in for one, but alas, I'll just have to wait... hopefully something else will pop up soon :)

I am also anxiously waiting for the pictures and videos that you will provide of this thing in action :D

Thanx;

Okay, folks - latest and greatest update - buckle your seatbelts !

I am sending back all the underspec units for replacements - the 6 that were stuck in customs have been sent back to the vendor. Once they receive the out of spec units (shipping them out on Thursday) They will validate the output power of the entire shipment, re-wrap everything securely, and use FEDEX instead ! Those damned DHL clowns actually sent me a bill for "handling charges" while the lasers were in customs. Jerks !

Anywho - I am looking at this in a great light - as in there is FINALLY light at the end of the tunnel on this damned ordeal ! Bear with me a little bit longer - it will work out for the best (finally !)
 
Very nice Greg! Thank you again for all your hard work, time, and money you put into this group buy!
 
Thanks - I FINALLY feel like there is a light at the end of the tunnel, now ! :-?
 
Hi SenKat, is there a chance that there would be enough bits of broken laser knocking about in the bottom of the box for me......I came on the scene rather late :-[

Greg, Thanks for doing all the hard work and putting up with all the Bull so we didn't have to.
