You know the saying TJ!

If you're not going big...

Go home... ! :D



I'll put some pop-corn on and come back when it's done...

Only joking. Sorry.

I'm trying to cover my house in an IR beam web. I have plenty of low power IR diodes, I just dont want/afford to have to add 20 drivers to the set up.
 
They have IR spiders building beam webs now too?!!! :eek:

I'll take my pop-corn somewhere other than your house then! :crackup:

Something with this thread gave me a thought. I have seen the beam produced with the knife edge in this projector. It is ugly but is that because the stock lenses are not that great? If so could you swap out all the stock lenses for Aixiz 405 lenses and get a nice 24W beam out of the unit?
 
Awww, you didn't let me finish editing my above post... :( I want to see what CJ makes of that.


To your point though DTR, I don't think the beam would be pretty. You'd have to use other optics to get the dimensions down, (telescopics). I suspect they did something similar with that huge gimble mounted laser shining over a European city not so long ago although I'm not sure if they used the knife edge parts or just tidied up the raw beam.

He tends to eat a lot though.

I can take the wind out of anybody's sails.:p

I would not worry. TJ is the ultimate troll. He will find it like a mouse looking for a piece of cheese.;)

EDIT

And he did.:D

Hey TJ nice spider. Does that thing have four eyes?

From what I read the knife edge in the projector has too steep of angles to properly collimate.

Oh. I thought the crappy beam was from the lenses. Would have been a good idea is it was just the quality of the lenses.:beer:
 
Ahh, I love those little jumping spiders! I had one hanging around my room all summer a few years ago. A Zebra Spider. Cool critter and looked like it could take your leg off in a macro shot just like that one! I called him Boris, (I don't really know how to sex a spider so I assumed it to be male!). I would post his face-for-radio here but the HD storing the image was toast a long while ago. Those eyes... You know they have moving parts inside them? Seriously weird.

A tad off topic but hey...

Well its meant be to a light source, not a laser beam. So I dont they cared if it would collimate or not, LOL.

I like Boris. Seems to fit.
 
@ T_J: nice spider pet ..... er ..... does it bite, if you don't give him his cookie ? ..... ;) :D

@ DTR: spiders eyes are extremely varied and specialized from species to species ..... usually, a spider have eight eyes, but some species have only six or four ..... there are also species that, inside their "main" eyes, build each night, and destroy each day, an extra sensitive layes for very low light levels (some have almost 5 times more sensitivity than cats) ..... if that is a jumping spider, it probably have eight eyes ..... two couples of "side eyes", that it use for defense (back vision) and for see movement, a couple of "middle eyes" that works like a telephoto, for target and lock the prey, and the "main eyes", that it use like a telemeter, for precisely calculate the distance for the jump to the prey .....

Just wondering how can be, for a human, have to manage a similar sight system ..... a continuous headache, probably :p :D
 
Man if we had that many eyes protection for this hobby would be putting a box over our heads.:p

It is really neat how some of the eyes are different sizes.
 
God help any police 'copters with IR night vision flying over T_J's house , it'll look like Las Vegas :)

And they'll be blind.
 
Heh, i think spiders have one of the more complex sight systems ever created ..... i don't know all the details (i'm not a specialist :p), but i've read something, about it, in the past ..... some of them see IR with a pair of eyes, and normal light with the others, some others see high sensitivity and low resolution laterally, and binocular like a telescope with the central ones, some have "variable sensitivity" main eyes (their phisiology "grow" an extra sensitive layer inside the eye, when the night fall, and destroy it at dawn, each day :p), there are also some species that have one eyes pair that see polarized light only (and i don't know the reason ..... what utility can have, to have a pair of eyes that see polarized ?)

Spiders are, someway, strange creatures .....
