Disassemble it. Take it one step at a time. Double check and test everything at each step.

If this pisses you off, maybe you shouldn't be building lasers. I have broken lots of stuff ;)

Peace,

Yep..did that twice..then like i said^^ i used a diff driver...

Can you set and/or adjust the current when using a dummy load with either of your drivers?

Yes on the one i can. I tested it with an IR and a Red LD--no prob at all. Its this BR thats giving me a problem...and i dont feel like buying another, since the LD isnt dead....it just isnt.....finding a more powerful life. lol

I actually got burned(felt like a bee sting) by a phr at 90ma with aixiz glass lense, when my hand was at the focal point(about 6" from lense) while adjusting lense.

I have the same experience with a Daedal-built PS3 diode box/pointer. I believe he wrote down that it's 19mw, but it doesn't seem much brighter than my 9mw pointer. (I know, I know, human vision, 405nm, etc..:))
I'm a pasty fellow, so it surprised me to feel it on the inside of my wrist. If I sharpie myself, it stings fast and it's not pleasant.

20/20 only tells you how well you focus, not how well you perceive that wavelength of light. my parents have comparable vision, but my dad sees the violet much better. some people just don't see it as easily. my 100 mw non focusable laser's beam is visible at night, but not at all in the day.

IF the IR and red diodes work normally, and the violet diode does not, then either it is not getting enough voltage or the diode is blown. Those are the only two possibilities. LED light CAN be focused.

Thanks, but my eyes are pretty much as close as they get to perfect. :san::san: Its just that apparently i got a gay diode this time around

Your diode seems to have nearly no output. My 10mW bluray will cause white printer paper to fluoresce a very bright blue where the spot hits it. You sound like you have a dim violet LED at best. Also, as mentioned a few times already, 6V is not enough for a bluray when you use a linear driver like the LM317. You need at least 9V, you can test off a 12V bench supply to rule out bad batteries. The bluray diode needs about 5.5V and the LM317 has a reference voltage of 1.25V, but needs a little more overhead. Two fully charged lithium cells totalling 8.4V is usually the minimum to run a PHR and linear regulator of the LM317 type, three lithium cells is better. When ordering laser diodes, it's best to get more than one. It's Murphy's Law ... if I only have one LD and need the laser badly, the LD will be dead already, or I will drop it and step on it or something like that. Get a new diode and go through all the steps. Bench power to regulator and test load, verify and set current, disconnect from power, short cap, solder LD (quickly, no overheating), if it's winter where you are, use antistatic precautions, test driver and LD off bench supply, if good, test off batteries, if good then assemble laser ...

Best of luck, you will succeed!

Just be happy the PHR 803 T diodes have gotten so cheap. Imagine how you'd feel if that was a $200.00 + 12 X diode ?????

Perfect? Really? Have you been wavelength tested? What are your eyes range in nanometers?

Remember when we were paying <$50 for a drive just FOR THE CHANCE that we would get a PHR rather than a DT ?

Did you break the diode window? It is a small piece of AR coated glass that covers the hole where the laser is emitted.

It seems to go on and off. But for now it seems to be working! I have it at 125ma.... +/- 15ma...it pops balloons nicely..doesn't light matches tho..??..burns black material. A SLIGHT beam at nighttime. Using aixiz module (one off DX from a 5mw red) which may be the problem. as they are "crappy"
with their lens. With this laser (BR) i have to have it focused to a "pin-head" in order to burn. But its fine i guess. I eventually might just set it to 60ma and mod my airsoft thompson M1A1 for glow-in-the-dark BB's.
