Hello, what would happen if someone were to be in the same room as this machine, a 3000mw/450nm laser engraver without protection? Is it true you would go blind, flashbang style?
What are the actual dangers and their specifics?

Oh misread that, the laser stopped working, fan is on, moving thing is on, software is on but it wont turn on now, arduino issue, so that's nice, I still need to be sure it goes away now, he can always get another.
They're seeking to repare the arduino, or find out whatever happened, not even I know, it could have been fixed today, if so I'll run away now but tell me more now please

Buy exactly the same laser engraver and place it in your room, turn it on everytime your neighbor does.
The laser waves will interference eachother out of phase because of same frequency, the interference will cause them to cancel eachother so all their energy will be lost

Be honest with me, can they reach my room or not? Can the photons remain in the air if I open the door after the laser and fuck my eyes? I'm an artist.
I will be sending myself to a mental institution for a year before that happens, I don't want to be around it when it's on

You dont look at the laser but looking at the dot is still like looking at the sun. Your eye picks up some solid angle of the radiation sphere and this power is focused on a single spot on your retina.

ask /b/.
i mean /sci/ is technically the right place, but since /b/ has more traffic, you might get more engagement.

Just wear laser protection googles because you never know, they are mandatory in all companies and labs that use lasers.
