You guys probably already saw this... but :)check out this laser harp build. This is really cool. I would love to build one of these! ARDUINO LASER HARP WORKING PRINCIPLE 1 - YouTube

If anyone is interested in making their focus ring action smooth like butter... I just put some thermal paste on my 405-G-2 Glass Lens Focus ring and now it has just enough "ease" and resistance... before, it had a lot of play... rattle... bump it by accident and it turns wildly... anyway, I...

fyi: Titanium is fairly hard (although not as hard as some grades of heat-treated steel), non-magnetic and a poor conductor of heat and electricity. Machining requires precautions, as the material will soften and gall if sharp tools and proper cooling methods are not used. Titanium -...

Thanks for all the constructive comments. As I am new to this, obviously I dont have any idea of pricing etc. The picture with the wires coming out of the module confused me I guess... I bought my first 445nm blue laser diode module and driver from DTR. I was very satisfied. However, I ignored...

Apologies up front if this is the wrong type of question or asked in some improper manner... Can anyone tell if the link below includes a driver? Brand New 445nm 1W (1000mW) Blue Laser Diode in Aixiz Module HighTechDealZ - 445nm 1W (1000mW) Blue Brand New Laser Diode in Aixiz Module

Thanks, I will search the forum again.... no luck yet... lots of stuff but no specific video showing the test for current with a laser driver... I guess everyone assumes that the viewer is not a noob like me and skips the basics...

thanks for your reply!!! I'll check it out!

Anyone have a video showing how to properly use a multimeter to measure current on laser driver using test circuit with explanation? :shhh:

Very nice!

Anyone know of another place to purchase these kinds of beam combiners? Quad Beam Combiner ELITE | Micro Laser Labs This one combines the output of 4 separate laser diodes into one beam. :thinking:

I am looking for a rectangular "box" host that I can attach switches, temerature readout, and other controls... for my laser... cant seem to find anything on the web that I like. any ideas?

Hi, I bought 1.3W 445nm Blue Laser Module W/Microboost & 405-G-2 Glass Lens here: https://sites.google.com/site/dtrlpf/home/diodes/445-m140-didoes I want to house this in a box with switches for "master power", "arm laser power", and "fire". Inside I want the laser, heatsink and fan. The only...
