    First laser build problems

    Thanks Jordan, I went ahead and did as you said and tested the diode and it does indeed work. I then did a closer inspection of everything and noticed that a small part of the battery board was bare (like the metal contact point was worn off). To fix it I simply soldered a small amount of solder...

    First laser build problems

    Alright, I got the laser back from DTR today. I immediately set to re-assembling it and soldering everything in place. I put freshly charged batteries in (being VERY careful not to reverse them), pushed the on button and........ NOTHING. The laser does not work at all!! I have taken it all...

    Very basic and probably dumb question.

    Shadowsix, Thank you for the suggestion. I just ordered some 5A 40V Schottky diodes. I could only order them in much larger quantities than I need (40 pcs), but they will be here on Monday. I decided to get the 5A 40V ones because I am running the driver at 2.4A and wanted a little more...

    Very basic and probably dumb question.

    I simply wired the negative (black wire) from the diode to the negative (black wire) of the battery board. Same with the positive (red) leads.

    Very basic and probably dumb question.

    I recently built a laser using the survival lasers black anodized Host, copper extended heat sink, copper pill, 9mm 445nm diode from DTR with his 2.4A driver. Everything worked great at first, but I soon started having issues. I sent it back to DTR and he fixed it for me. He said that I probably...

    Thanks DTR, PM me your address and I will send it out to you.

    First laser build problems

    I have three lenses and they all look the same. I haven't burnt anything close up at all. I am more impressed by the burning from a distance. The only thing I burned was a match from about 15 feet away. The laser was fine when I turned it off, but about 5 minutes later when I turned it back on...

    First laser build problems

    That really sucks. I don't see how it could have overheated, I only ran it for a few seconds at a time. It looks like I am done building lasers for a while. I just can't afford to keep dropping money on diodes. I've already spent almost $200 just on diodes. At this point it has cost me like $5 a...

    First laser build problems

    I am using a three element glass lens from DTR. I think it is the diode. Here is a raw output shot (no lens).

    First laser build problems

    I take it back, I already have another problem. The divergence is suddenly all over the place. It started out very normal, but now I cannot focus the beam well and it is a weird shape. Here are a couple of pics. What happened and is there anything I can do to fix it?

    First laser build problems

    Got the battery board and pill today, put everything together and the laser is now alive. It definitely has a lot more power than my roommates 2W 445 laser. It burns EVERYTHING much faster than his. The only issue I have now is the duty cycle. I knew that it might be a short duty cycle with this...

    First laser build problems

    I got the new diode with driver from DTR's today. I cannot fully express how impressed I am with the level of service Jordan provides. Now I am just waiting for the new pill and battery board to arrive. They shipped today, so I expect to see them by Wed. A couple of other things I ordered...

    Thoughts and Advice needed

    Great, I guess I will see how warm it gets and adjust my duty cycle accordingly. Unfortunately, I accidentally toasted my first diode, so I ordered a new one from DTR. This time I decided to get the diode with the driver all ready attached. This means that there really is no option to heatsink...

    Thank you. I actually ordered those yesterday as well.

    iPad problems on LPF

    It does not happen once I have logged in. The trouble is that I don't even have time to log in before it kicks me into the app store. Is there anyway to delay the first ad for, say, 30 seconds to allow time to log in?

    First laser build problems

    I checked the driver and it was operating properly. The only thing that would not work was the diode. I went ahead and ordered a new diode from DTR's Laser Shop. This time I went ahead and ordered it with the 2.4A X-Drive driver already attached. I figure this will keep this headache from...

    iPad problems on LPF

    I have noticed this on my ipad and iphone. It is quite IRRITATING!

    First laser build problems

    It looks like this is exactly what happened. I did not even think about shorting the driver before re-attaching it to the diode. I have already ordered a new diode from DTR. I guess I can check this lesson off. It has been learned, never to be forgotten again.

    First laser build problems

    The switch is not the problem, I have already gone through all of the steps to check it. Unfortunately, I think I damaged either the driver, or worse, the diode. I guess this time I will have to order the diode with the driver already attached from DTR and hope for the best.

    First laser build problems

    These are the best I can get. The Diode came from DTR with the leads soldered on. The driver is mounted in the brass ring and soldered to the pill, so I can't get pics of the connections to the driver. The driver came with the leads soldered to it as well.
