I have a history of killing 445nm diodes, probably $300 in the hole over a period of 5 years. Not from too much current but from overheating or too long a duty cycle. So I just bought one of DTR 7w NUBM44 V2 450nm Diode In 12mm Copper I got the 12mm so I could attach a thermistor connected to...

Copyright © 1994-2004, Samuel M. Goldwasser So, many led and laser diodes seem to only have a voltage regulator and a diode for reverse battery protection. Some have current regulators, but all the green ones seem way more complex. I'm interested in using the following laser in a project but...

So what is recommended for measuring Class 1 IR laser compliance? What kind of money can I expect to spend?

Needing some answers to an idea I had. From the time I watched the first terminator, I've thought of a 40w portable laser. Just wondering if I could make the below idea work, or if the wavelengths would cancel each other out. Take a 90mm makutov telescope. Build a heatsink in front of the...

Just now getting into green lasers, Not familiar with the diodes in common usage. Looking for something around the cost and as usefulness as my Jayrob 445nm build. Any advice and option suggestions would be appreciated. Thanks

I have a mini 904nm diode and the lens is so small it can't easily be cleaned and a little dust messes up the beam. In front of the diode is a .4" cylinder shape area I can put a sacrificial lens. I guess I can either screw a module into this place or bond a lens in this area. Any idea where I...

I've been keeping to the norm and using flexdrives set at 1.5amps, but they get pricey when you have several projects going on. There is a plethora of LED drivers ranging from 300ma - 750ma - 1,400ma on ebay that can be had for less than $6. By combining 2 or 3 of these you could achieve a lot...

I've got a little project going. I've got a 1.4" tube to work with, and need to cram as much battery power and axiz modules that I can in it. My favorite battery is the AW 18650's, I can only fit two of them in the tube, but I could change batteries if the benefit is great enough. I'd like to...

I wanted to try my hand at casting and pooring some custom heatsinks. Obviously some metals are a lot easier to work with than others. I am looking for something is affordable, has a low melting point, and will work well as a heatsink for my 1.8w lasers. Any recommendations?

Looking for some round safety lenses. One for 445nm and one for 808nm. Anyone have a quality source that will not cost a fortune? Thanks

Thinking of getting one of the cheap 1w 808nm laser diodes from ebay to do some testing with. Where can I get a suitable Axiz module lens for it? Can these types of diodes be focused at longer ranges? Thanks

I was looking at the new 2w 445nm laser posted over in the review section. With that massive heatseak I saw no reason that both an IR and a 445nm laser could not be mounted in it at the same time. To keep it simple since there would not be much room left on the back of the heatseak I would want...

I need some circuit boards with battery contacts on one side and pos. and neg. lead wires on the other. Like a Cree LED Driver but without the electronics. Any help would be great. Thanks

Whats the limit on this diode? I've seen 1.6w reviews. How far can we push it? I'm curious what it could do if it was only on for 10-15secs and had a cooling fan on it.

What are the differences in these, pertaining to distance they can burn/focus. Beam quality .etc Is one perferred over the other for IR spotlight purposes? The IR lasers I have all display lines of illumination.

I was approved by wicked lasers for the G1 model, but they sent me a Smart Switch version of the laser instead. After waiting for over 3 months I am tired of dealing with them. What I need to do is have the ability to activate the laser instantly and remotely using my own switch and safety key...
