Heya everyone!
Just completed my brass bar laser!
At the time of this post, I don't have actual pictures, but here's my finely edited HD video of it.
I filmed and edited a full video showing how to make this, but its not complete yet, so here's just the tail end of the video:
Homemade 1.2 Watt brass bar blue laser - Burning Power! - YouTube
Enjoy!
Details:
DTR 445nm diode.
LM317 driver circuit (with 1 ohm resistor)
2 heatsinks on the LM317 (plus heatsink compound)
12 volt computer fan (although it actually cools the regulator more than anything XD)
Made from solid brass bar. The fan isn't even needed. It still stays ice cold!
Tap-threaded hole and set screw for Aixiz
Click on/off square switch
Steel grounded power adapter port (for versatile power input)
The only parts that weren't laying around my basement were the diode/aixiz, and the lm317 and 2 watt resistor.
Still waiting for my glass lens, so I'm playing it safe and letting it rest until I get it.
