Hi all, I was thinking of building a 2+W 445 from one of the new 9mm diodes. I will definitely by buying a pair or rated and certified 445 glasses for use indoors, but I plan on using it outdoors quite a bit too, and I was wondering, what would be a safe distance (assuming a nice matte object...

I did not have it in a custom made laser heat sink, but I had it surrounded by some scrap aluminum I had and had a fan on it. It did not get hot and blew pretty much immediately, so I don't think it was overheating that did it.

Yes, I do have a capacitor. I believe I did short its pins before I attached the diode through, if that's what you were getting at.

That might well be, I forgot the dropout voltage of the driver was 3V. Will the diode in the driver drop voltage as well, like it does in a test load? Anyway, when I put 2 9V in series to test it, I believe it killed the diode for some reason, it certainly does not work anymore, or even LED...

Hi everybody, this is my first post here, so I apologize if I ruffle any feathers, but here goes. I have build a PHR-805 build using a LM317 driver with a 10 ohm resistor as the adjustment, such as described here: Laser driver - It can be done. I am not using a pot for the PHR-805, just the...
