Aixiz(3) Predator's sight....

[Spyderz20x6]

So each diode is individually powered? How did you wire it up so each battery powered one diode?

They are all powered from the same source.  Look closely at the picture.  The lasers are case positive so you see the positive wires being returned into the head to make contact with the body of the host.  The negative wires are joined and connected to the negative contact in the host.  Each of the laser modules has its own driver inside the module.  So it is one power source, powering three different drivers, inside three separate modules.

Ok, thats how it though it was...

i love that tri-laser!
i thought long ago how to get a cheap grating that does this, split it into three beams.. heck, they do much more complex (and silly) patterns in those "laser with 100 pattern heads"!
the only reason i didnt build such a module from 3 lasers yet, is, that i cant think of anything to use it for.. but then, i still "use" my other lasers too?

A grating wouldn't work because those diverge and the projected pattern is bigger and bigger farther away, so your 3 dots would have horrible divergence, be really blurry and also diverge from each other. :-/

If you want to use a single laser you could split the beam 33-66 then the split the 66 beam 50-50 so you'd split your beam in three 33% beams, then use mirrors to align.You'd need 2 polarized beamsplitters though, and lose some power through mirrors and stuff.Better just use 3 lasers.

Would be cool to have such an optic to shine any of your lasers through and get an instant predator sight

The predator's sight has always been, is, and always be, 3 separate lasers, ok. ;D
Yeah, Switches post gave me a headache. More optics, more money, more work... I spent $7 a laser, and now you can get them for less, so they're not that expensive.

Hey , how can you be so sure? ;D

I mean, what if you wanna make a predator sight with 488nm?You're not gonna buy 3 argons are you? ;D

My concept could be doable with optics from 2 PS3 or PHR sleds.Though I have no idea where would you mount them all in :-/

Ermmmm . . . .Because, so far, as far as we know, IIRC he and I are the only ones who have made one besides the movie makers. I'm fairly confident that the movie makers would also use the easiest and most cost effective way to create the light. No one else has tried any other technique. At this point, Ace's statement stands. IF you build an optically based predator sight, only then will your question about confidence be valid.

Empericism vs. speculation -- it has always been thus

If you built the 3 lasers around a piece of tubing, couldn't you laze a 4th laser down the center of the tube, & use the resulting beam to align the other 3 at whatever distance you chose ?

I'm not sure I understand exactly what you mean, but technically, you could "wrap" as many lasers as you want around/inside whatever you want aligned however you want.

Yes, but maybe in the movie, the Predator's sight is supposed to have an optically based sight I mean, why not, since his technology is so advanced? ;D

But yea, just speculating... :
