I use AixiZ 445 glass lens..
I cant remember did I short the drivers connections... Stupid me.
And I only soldered two wires together, I didnt solder the diode directly..
And the laser could burn matches etc - but Imo it wasnt outputting ~1.2W
Then just one morning, the dot has turned to that (picture in OP) :cryyy:
Now the laser wont even turn on...
@Eudaimonium
Alright, I'll make a picture of the build soon.
I will check the connections. Thanks
Edit:
Okay heres some pictures of the build
It goes like that
Here is my driver pill soldered to diode (sorry for bad quality)
Everything looked okay from inside.
