Flugufrelsarinn's first build. 12x S06J *Ghetto warning*

I have always loved lasers. Since my dad gave me a little 5mW red laser as a child, to buying green lasers from China over the past few years.

I am almost ashamed to post this up here seeing some of the beautiful lasers you guys have put together on here.

I decided to try putting one together on my own. It is not finished yet, I am going to mount it in a project box to hide it's ugliness and solder in a few more voltage source methods.


The heat sink is a slice of a Al cylinder. I had to use a dremel tool to cut it because my cut off saw began to malfunction. I applied Arctic Silver Alumina thermal compound. Aside from how bad it looks, it hardly gets warm (80*F) after minutes of use at 400mA.




I also took some beam shots. The camera has a hard time handling the brightness. The camera is on a tripod below and to the right of the laser "dot." They were taken with the laser set to 40mA, 220mA, and 440mA.

Very nice man I love how the purple looks in the pictures!

Great job so far, nothing to be ashamed of. You can make it look nice in a project box. I know what you mean about the camera having a hard time handling the brightness, my cameras don't like lasers either but your beam shots look good. I look forward to seeing it when finished.

I bet it did if it is an abrasive disc saw. Al will gum up the discs on those rendering it
useless. The Dremel couldn't have been much better. The thing to use would be a hacksaw,
not to be confused with hakzaw.

Hakzaw1 is my favorite 'tool'

Looks good op. Nice beam at 440ma

Thanks guys!

I will update this thread whenever I get it mounted in a project box.

my first build was a violet in a project box. worse damn thing ever. its gone now. one day while sitting around i decided to take it apart. lost the module and so its gone forever. Oh well.

it is kinda, well, crude. but you built it yourself and it works. good job!
if i'm looking at your power supply right you have a lot of volts going to it at .442A.

^Ditto. I also noticed this, I am pretty sure you should not exceed 6.1-6.2V if you're using a CV supply. For laser diodes CC is recommended for a reason nevertheless good luck for the completion. The beams look pretty strong too your camera is definitely still better than mine. :gj: +1

It looks like he's using an LM317 driver. The input voltage isn't going to matter much with one of those
unless it goes over 32V. They can take a real beating.

Love those diodes I made one in one of jayrobs stainless kits years ago
