Hi all, this is my first post. And my first build.
I used:

-Aurora C6 host
-445nm M140 Diode In Copper Module With Leads*
& 405-G-2 Glass Lens
$72

-1.25A Diode Driver
-2x 16340 CR123a 1000mAh 3.7V batteries

I soldered the brass ring and the driver together. I soldered the driver to the diode. I attempted to turn it on. Not working. I never touched the wires of the diode with my hands, because I learned from LPF that this could damage the diode. Now I can not see something I did wrong, so my question is, did I get a failed diode? Or is it a damaged driver?

I am from the Netherlands btw

Thank you for your help


EDIT: It Works, I dont know why, but maybe it is the switch. Now I get a rectangular spot even if I focus the laser. Is this normal?
