Hey everyone, I dont really post here often but I lurk enough to know this is feasible.
What I want to do is make a 445nm laser show thats bright enough to be seen in a well-lit room, but not harmful for eyes.
So a question on that would be: around what power is it safe to look at 445nm on a WHITE wall from a distance of a few feet? (printer paper on a door actually)
I also would like to know what kind of software i would need / need to develop in order to spin one or two mirrors to display a name and logo, and how compact i could possibly make it.
I have all time until next September to make this from scratch. So far, i took apart an old red laser show and hooked up my arctic to a decent holster and pointed it at the mirrors :crackup:
(I also never realised how well yellow paintball glasses worked with blocking 445nm light until today, turns out the pair works better than WL's goggles)
one last thing before I forget:
