Sincerely investigate any of these three short quotes as new concepts and you've taken your first step into a larger world:

"I regard consciousness as fundamental. I regard matter as derivative from consciousness..." - Max Planck. "Everything we call real is made of things that cannot be regarded as real" - Neils Bohr. "What we call physical things and events do not exist independently of subjective experience..." - Deepak Chopra.

Each of these three rabbit holes go deep, ending up in the same place.

Useless troll fighting.

oh boy another golden thread from LP:
1) typical not to be trusted chinese driver
2) theres an ebay thread for this, not that anyone cares about those drivers anyway
3) what are you surprised at? that they are mass produced? why do you think they cost like 7$ a piece?

They don't look like they would handle the current for a two watt laser diode from the size of that small semiconductor device/valve on it, but maybe it will. They sell these drivers for eight bucks if you just want one. I have some much lower current blue single mode 450nm diodes I'm considering them for, maybe try one and see if it will adjust down to 300 mills. I'd rather have a driver rated for a higher output running at low output than the other way around, if it will adjust that low.
