Woah, what a fitting name for such a beast! Great work Petros, +1 well earned bud!

Re: Blue Destroyer ( 2 W 445nm )

Thanks dlmb, I think I can do better than this, but the lack of creativity sometimes doesn't let you come up with better designs :( Anyway I like it very much! Plus it's my most powerful laser atm :D

@ Trevor, you earned the name. I call this the Lizard laser from now on. :crackup:
No kidding :)

you know that you can run a +12 volt and use the +5 volt for negative you get 7 volts right? that is if that is a computer power supply.

^It's not.

Isn't brown line and blue neutral?

I see there's a voltage adjust pot. Turn that down.

How about a 12V fan hooked into the unused terminals ? Forced air cooling with a filter (to control dust) and lots of 12V fans are bigger which means they can run quieter and slower for less noise while cooling.

Nice laser!

Do you have a link to that power supply? I've been looking for a high amperage 24v one and I think two of those would be great.

12V 5A DC Universal Regulated Switching Power Supply | eBay

It makes no noise while ON and has small safety delay by the time I hook the power cord to the mains till the laser turns on. I like it very much. I don't know how much it will last but since a lot of people use it in their projectors, I gave it a try.

@Cyparagon, I was told that the voltage would drop no less than 11+ V by adjusting that pot. Same applies if I wanted to exceed 12 Volts. Or is that incorrect?

What laser is that? And yes, my camera sucks. High exposure time makes the image too bright plus these 445 lasers make it even worse ^^ I will get a new camera soon :)

Do you guys think the cree driver would handle 12v to power a 445 @ maybe 700ma with continuous duty cycle? Would sink the driver of course.

Or do you think rather go with a sinked lm317??

This is a very cool looking build. It looks dangerous even to the untrained eye.

Which is good. That big heat sink even if you have no idea wtf a heat sink is looks like serious business!
