Thanks for the quick reply and for the help!
and yes I use 190nm to 540nm 55% faded red googles, my eyes hurts even when I only point at the wall :D
I'm not pretty good at powerful lasers so I started out with a ebay laser :)
yeah I'll post a picture for scales.
Just got my blue laser pointer from Ebay and I'm new on this forum.
It's powered by 2x 16340 3.7V 1500mAh batteries. As you can see here on the pictures it was pretty well build and was pretty good I could say for a blue laser pointer, it burns pretty well and I'm going to post a burning test...
