Hello Everyone,

This is my very first completed laser project :D I got an A140 diode already installed in an Aixiz module from Danglasers. I made a LM317 driver with a one ohm resistor to bring it to near max current. The whole thing is crudely mounted on a 9V battery holder.

It was getting late, and I was determined to see a blue laser before I slept :P

Here are some pics:

yeah, but im not turning it on for more then a second or 2. Its not getting warm because of that. I plan on making a whole lab setup later. This was just to see it in action :)

I have a spare AMD cpu cooler with heatpipes. Im gonna make a metal adapter so i can slap a TEC between them.

Hopefully :P

Shamefully, I do not. I have a pair on order. I have only used this very sporadically to aim at the sky (away from anything moving up there).

Its astonishingly bright.

Until you get safety glasses I don't reccomend using it and if you really must, only point it at the sky. It hits something beside the sky (such as something in your house), don't look at the dot especially if the surface is white.
