    great instructable, i have a slight question though.
    this is how it works? the infrared led's send out infra red light. which the naked eye cant see. however the night vision state on the videocamera can pick up IR, and then use that to generate the image, instead of regular light?

    my question is this then, what if you used normal infrared googles? like theese https://www.instructables.com/id/Homemade-Infrared-Goggles!-For-Under-%2410/ <---. shouldent you in theory then, be able to see in a completely dark room, lit only by infrared, since theese googles will allow you to see the ir?

    you can try it out just don't look directly in to the leds. i don't think it would work because i don't conciter those true infer red goggles. heck if they would work y would the millatary use big expencive ones when they could use moded welders goggles and leds.

    well im confused, are you sure the military ones have lcd screens inside the googles? i dont see why it shouldent work :S maby a reason to use a digital screen is that then no matter how much infrared bombardment there is your eyes wont take any damage as their only exposed to the screen? if anyone can explain please do.

    Human eyes cannot detect IR. Using an IR filter gets rid of the visible light and leaves only the IR light that we cannot see (detect). If there is enough IR light, our eyes can still be damaged by the IR light, even though we cannot see it. That is why IR lasers are so dangerous. You don't "see" the light until you are already blinded by it. Think about ultrasonic whistles for dogs. Human ears cannot hear the sound, but dog ears can. It doesn't matter if there is absolute silence and the ultrasonic whistle is the only sound, we still cannot hear it. Same with IR. even if there is no other light (because the IR filter got rid of all the other light) we still cannot see it. The light energy is still there however and can still damage our eyes.

    well, damage to your eyes depends on the brightness of the screen. also, if there too much infrared, you can fry the camera sensor.

    im asuming thay have lcd screens because they cost thousands but i have never checked i got to play with a pair 4 years ago but naver thought to look at how they worked just put them on my head and flicked a switch

    Hi, Sorry for digging up an old post here, but i spose its good for when other people read through this...
    it wouldnt work, those goggles filter out most visable light and give an infa red effect and allow some form of IR, BUT  infared is invisible to the naked eye, wether the rest of the spectrum is blocked out or not.  the way the military do it is using a small CCD camera, these can detec IR and will show it up on screen as a light source,  it would be awsome if we could see IR and use things like that though :(

    Do you know how short the range is on that? It's virtually useless unless you get a lot of high power LED's and a large power source.

    I've got to admit, I'd never heard of them before I saw KipKay on YT talking about them - so I guess they're more of an American thing than UK..
