IR Videos





Introduction: IR Videos

With a digital camera in movie mode, or with a camcorder, the diy infrared filter can also be used to record videos, giving them an eerie and mysterious atmosphere.
However, due to the short exposure of video shots, it is hard to get satisfactory results with two pieces film. In the video on the first page of this instructable, as well as the one underneath, the footage was recorded through a single slide of photographic film, which does let in a fair amount of natural light, as well as IR light. The result is an hybrid, which has an interesting mood to it however.

Is there any way that there can be a mod that can make heat clear, like so:

People use infrared cameras for all sorts of applications. They're VERY effective for energy efficiency. If someone could find how to make a cheap DIY alternative to the cameras that are usually thousands of dollars, it would be of enormous benefit.

I'm pretty sure that thermal imaging cameras have heat reactive chemicals in their lenses that filter visible light out and make infrared heat more prominent. I don't think they use a normal CCD like you would find in a normal camera either. They don't have to be cooled, but cooling does make their images a higher quality.

There's still probably some way that it can be done.

From what I recall reading in the past these types of cameras are built using a ccd and a cooling device maybe you could try hacking a camera with a peltier device to cool the ccd to bring the sensitivity up. I'm pretty sure thats the only difference. I found this out after finding out that during my research on the "Stirling Engine" that they can also use the engine for heat transfer so they put them in night vision. This might help get you some extra out of the IR range... It would be worth testing the theory. I have also wanted to know about where to get a cheap heat cam because those home wasted energy surveys are pretty neat and would be a pretty cool job. Though its not a big focus of mine just have some vague info on them.

I'm replying to this months later...
That is really, really interesting. Do you have some info on how the stirling engine works in nightvision?
What is a peltier device?
I wonder how far you could go into IR... do you have any idea?

From what I read years ago some night vision work better when the CCD is colder thus being able to pick up IR a bit easier, so the stirling engine comes into play here by acting more like a heat pump than an engine. Google References: (shortened)  I basically stumbled across this information wanting to learn more about the Stirling engine itself.  

From what I recall a night vision setup with this configuration could essentially see in Zero Lux (complete darkness)  As to how far? I'm not sure, from what I gather there is two types basically of night vision theres ones that use IR illumination and ones that are passive.  Obviously the passive ones are the ones used in the field due to stealth issues but if you just need night vision for whatever reason illuminated seems fine but limited.

I've wanted to make an Instructable that would show you how you build a cheap diy Infra Red Spotlight/Floodlight but just haven't had the time.  It seems as though all the current day IR arrays are built from LED's which are still not even close to matching normal bulbs in their power and efficiency / cost comparison.  But most consumer grade Night Vision cost around 200 something some for less but you'll know why when you get one.

It's not hard. Open up the camera and take out the IR filter, then put a floppy disk / film filter in it's place. Heat shows up as blue-white to me; toasters/soldering irons can light up a small area. Stoves look particularly cool.

Really! I did a lot of research and was becoming convinced that this was impossible. I guess I was only trying to understand how thermography cameras work and realized it was very specialty components (phased array optics). I guess I needed to understand how more basic film tech works. Anyway Can you pleeeease upload some pictures of it? Also, can you see heat escaping out of or coming into crack in a window? That would determine whether you could use it for energy efficiency... Thanks a lot

Sorry, I misunderstood.. it's not nearly that sensetive, I'm afraid. You won't be able to see people through walls, etc; you need a heat source such as a toaster or a stove or a lighter, etc for this to work.

No, I didn't mean that sensitive.
I meant being able to, say, see heat coming through the crack of a window from outside a heated house.
Nonetheless, do you have pictures to upload, even if it is of toasters/ovens?
It would give me a much better idea.

In case you're all wondering why I'm so interested in this...
I read a while ago that the most energy efficient town in the US, Osage, IA, started by using thermography, and building by building, giving images free to people. They saw where their heat was escaping, and plugged up the holes. They now save an average of about $800-1000 per household.
I'd like to do this as well, and see if we can at least start out doing it as inexpensively as possible.
Maybe if we can all find a way, we should make a separate DIY.

An article to look over:

I've been in touch with the Municipal Utilities in Osage. They use the following camera, costs about $15,000:
