What about the Bayer filter? Did you leave this on the CCD? Was it integrated with the IR filter you removed?

I found another interesting use for an infrared camera like this. You can use it during christmas time to take a peak at your presents. The camera can pick up some of the lettering/pictures under the wrapping paper. It worked for me at least. If there are thicker wrapping papers, it probably wouldn’t. It probably also needs a good infrared light source.

Long time Hackaday viewer, long time poster.

I read through all the comments to make sure this wasn’t already covered but I would like to shed some light on your project vs. the other one.

Personally I found the other one is far more informative and the people like Markie and Geoff definitely did not read it. Except to copy and paste that bit of text. While Geoff, you may feel that he got the idea from you he did not. If you clicked the link that is under the text you copied from his site you would see that it goes to a different project, and by providing that link he does give credit. Also Geoff, you do not mention IIRC or Internal IR Cut Filter on your project, the other web cam project does. The other project also does the IR heat pictures as well. So I believe he did get the idea from that site since Ka Nai’a mentions an internal cut filter and does the heat picture as well on the electric stove.

The other project uses a Fuji FinePix 2300 while Markie’s uses a FinePix 1300. I can see why someone would think it is a rip-off of the other project.

But what I am disappointed in is you still continue to claim this as your own original idea, to do this to a digital camera and not a web cam, while you should be giving credit to the other project since anyone else who ever stumbled upon this would see the creation dates and see that his site at least inspired yours.

My final point, has anyone actually e-mailed or tried talking to Ka Nai’a to see his method, inspiration, or other hacks? I doubt it. He probably doesn’t even know this site exists yet all these people are going behind his back and either defending him or spreading libel about him. But I for one will bring this site to his attention, if for anything else just to get his $0.02 on this matter.

well, i can tell you for sure i didn’t see that one (I did see the webcam-hack like I said in the article), when and where was this featured?

This almost looks like a blatant rip-off of the same digital camera IR hack that was featured a while back. The same camera too. So what, he built a stupid IR pack and gets featured on here? Did anyone actually read the other one. His idea for an IR flash is much better and works better too.

Found it….

Anyone interested in making/aquiring ir flashes for cameras etc. Should definitely check out your local Army Navy etc. Surplus store. The milspec issue handheld rescue/signal strobe as cheap and very easy to find. Its actually a strong visible light strobe with a plastic IR filter. There are 2 kinds of filters; a slide on and a pop on. I much prefer the pop-on because the strobe will still fit in its pouch w/it on and it dont slide off at the WRONG time. If your just going to cut it up it probably dont matter. Dont buy one without the filter. Youd have to take it apart though to get it to be in sinc w/your exposure but I dont think that will be a problem for you guys. When your getting them, make sure you keep the nicest one for yourself. Theyre great to have. If you ever get lost in the woods it will save your life. Great for roadside emergencies/breakdowns etc. Other military people will know your military when they see it flashing though, lol!

Youd have to use multiple diodes from a remote ctrl to make a good flashlight. Ive looked at my remote beams through military NVGs and they looked pretty weak. Instead of buying led arrays for a flashlight, whats wrong with just getting a bunch of junk remotes and pulling the diodes?

Well, someone posted the wikipedia-link in my comments, which can be helpful for understanding why people aren’t glow-in-the-dark on this camera-hack ;-)

btw, thanks for the link :D

I used to have an old B&W Quick cam that I converted to IR that was great. I wish I hadn’t tossed it a few apartment moves ago.
I’ll have to get around to doing this with my Nikon 950 one of these days…

is there any type of film out there that would be able to pick up thermal wavelengths?

By: Justin

Justin — Tue, 25 Oct 2005 22:24:39 +0000

A typical CCD at max is able to detect wavelenths as high as 1000nm. The thermal wavelengths are at least twice that length if my memory serves me right.

16: boy, that would be GREAT! Unfortunatly, i’m afraid this is next to impossible. i can’t recall the exact numbers, but the frequencies of infrared that a digicam’s imager can detect are pretty far away from that of thermal. the band a ccd can see is really just barely outside the human eye’s range. the thermal band, however, is pretty distant indeed…

is there any way to mod a camera for thermal imaging? that way i can use it to detect heat leaks from the house and insulate accordingly.

Ok I can match that. How about 4 arrays for $15 + Shipping. Thats 60 Leds, with no need to worry about the circuits. The Resistors are on the PCB already. All you have to do is hook them up to a battery or some other power supply. Simple and easy.

Make me an offer if you want more than 4 arrays. I’m just trying to get rid of them.

sorry to be a dick justin h…
But I scored 50 IR leds on ebay a year or two back for 13 bucks shipped. They even came w/ the resistors needed to wire them to 12v. Some auctions include a pcb for like 10 dollars more that can make a nice 50 array.

good luck people, later.
