    hi everyone first time posting here. ive been looking in to buying a night vision camera for hunting but they are far to expensive so i looked on you tube and people are makeing them out of digital cameras and infrared lights. i have most of my stuff except the infrared bulbs and was wondering if i could use a 54 LED Infrared Illuminator Replacement For CCTV Camera and run it off a 9v battery and if so how would i hook it up? here is a link to the bulbs

    http://www.ebay.com/itm/54-LED-Infr...985?pt=LH_DefaultDomain_0&hash=item3a608ce6a1

    thanks in advance

    It doesn't say what voltage it runs from. My suspicion is that it may run from 12V. If so, it won't produce significant amounts of IR from 9V.

    It also doesn't say what current it draws. If the LEDs are running at only 20mA, then the drain from a 9V battery might be 360mA. If you're thinking of a small (type 216) 9V battery, then its life might theoretically be as long as an hour.

    it runs off of 12v. i was wondering if i used a 9v and 2AA that would get me 12v correct? i wouldnt have it continuously running for hours either

    You would be far better off with 8 x AA cells.

    so i could use that 54 LED Infrared Illuminator and hook it up to 8 AAs?

    Assuming it requires 12V, 8 x AA cells will give you approx 12V.

    this kit is already assembled if you want to use it. I also found this link which may help you further http://www.haydnallbutt.com.au/2008...our-own-140-led-infrared-light-source-part-1/

    what sort of camera you using? From memory if you use a cmos camera then there is an issue.... someone may correct me there but am sure it was a cmos camera I saw that said not to use the IR on it.

    anyway I found a heap of things by googling "infrared floodlight". hope this all helps

    im making night vision goggles and im using a digital camera and taking the ir filter off it, then i need to build some ir leds to put on it just like this

    it looks kinda funky but looks like it works good

    The latter one says it's for 12V, the former (which appears to be the same one you mentioned earlier) doesn't seem to say.

    so would i have to run 11AA to make it work then or how many batteries would it take to make it work. thanks

    At the very least you want 8 x AAA cells. However they'll not weigh much less than 8xAA cells, they'll last a small fraction of the time and they'll cost more.

    It makes no difference.

    To get more light you need more LEDs or more current through the LEDs.

    For a given amount of light (all other things being equal) the requirements for the batteries are not gong to change much. The made up boards look like the best option.
