lol those film pieces are a pain to keep in place. but do not try to use super gule to hold them, which i did. say bye bye to web cam lens.
i guess im still trying to get good at this DIY stuff. it shouldnt have been this bad though.

i tried this with my logitech quickcam….i no longer have a working quickcam.

the infared filter is hidden behind the lens, which is glued down and must be removed. i managed to pry one side of this lens up, so i thought that it wasnt glued down. pulling more resulted in the thing snapping in half. so..its glued down. i now have a new out-of-focus infared camera.

Awesome hack. I just did it myself with an old webcam I had laying next to the computer. Soggy Waffle I used superglue before reading your comments and it worked fine!

It’s a shame the sun is setting where I am. Without a large source of IR I can’t see much.

Allow me to add some information in the goodness of science. Not only is Coke (kinda) transparent in IR, Pepsi Max is too!

well when i used super glue it caked all over the lens and the photo paper, and i cant get it off

just as a little helper because I tried this today… you may attempt to use a fired .45 (.50 would be beter but .45′s are more common) shell casing as a guide for cutting out the little circle for logitech webcams. a small paperclip properly modified (bent into a circle) and wedged in place will hold the film pieces in place very well.

if anyone is wanting to get rid of an old webcam i will gladly accept them… pedro_gonz@hotmail.com

Cool. I tried this with a cheapo webcam I had laying around. Works great. I used wood glue to fix the filter..

Now to find a good use…

This is kind of funny! I did the same a couple months back with a Logitech Quickcam 3000 and it really works well. Instead of using the film to block visible light I used the Kodak WRATTEN Gelatin filter(No. 87C) It’s meant to do that job and it’s very easy to cut to the squared shape filter holder.

#16: duh, just remove the IR filter in a camcorder

did it with an old webcam i had lying around, the ir filter was easy to get to, but the only way to get it out of the way was to break it, so i did. it was getting dark outside so i used the remote control for lighting…

I tried it with my Logitec Quickcam, but I couldn’t get the filter out. I ended up just scratching the lens a whole lot, and now I have an unworking quickcam, like #4. Alas

wasn’t this on hackaday before? And wasn’t there a brand of webcam which coated the lenses with a ir filter “paint” that made it so you needed to get a ir filter-less lens?

What would happen if you removed the IR filter and didn’t add a visible light filter?

i used my lego cam, but i couldn’t find anything that looked like an ir filter. just stuck the negative thing in and it can see the ir light just fine. The only problem is is it’s not fixed. sometimes half of the veiw is in ir only light and the other in normal color. what is weird is i can see the ir in the color half also, and i seriously did not remeber it being able to see it before. I repeat: I DID NOT TAKE ANY IR FILTER OUT. which is kindof weird.

I did this with both my logitech quickcam and an old digital camera (Ir cam to go! :D)

and what -WOULD- happen with no filter at all?

every webcam i’ve seen has a LED on the front to let you it’s on. has anyone tried replacing it with an IR LED to provide illumination?

to #26..

If you don’t place a Visible light filter in then when you use it with normal lights on or in sunlight then the sensor will do one of two things. 1. Explode..just kidding.. #1 is actually not focus correctly. The #2 is be washed out or have other color incorrectnesses.

If anyone has any used or even damaged webcams they want to get rid of, send them my way ( I’ll pay for shipping or something like that).

I am a complete noob at anything to do with electronics, but even I got this one working. My problem is finding out how to get my stuff to stay on the lens.

I had fun looking at stuff I own with this :)

:o neat!!! ;)

Hey! This is a great (and cheap) little hack. Thought about it for all of 5 seconds and realised a great improvement that someone with a bit more free cash might want to try. Would it not be possible to hook 3 of these together, each with a different filter, transmitting different parts of the IR mid-band to get a false-colour thermal imaging camera? Only problem I can see with this is that the cheapest filters in that part of the spectrum are

This is such an awesome idea. I tested it on my 3Com Home Connect USB webcam with sucess. So I took this same principle and modified my FujiFilm Finepix 2300 2.1MP Digital Camera. I also slipped a piece of the burnt 35mm film in front of the flash and now have an awesome IR digital camera. I may get some better filters in the future but so far so good.

Very cool!

Just did it, and added a few IR led’s to it, works great. Logitec quickcam. Used hammer and small screwdriver, drove the screwdriver between the lense and the barrel, pulled out and the lense poped out.

This is actually amazing I made one today. Anyone seen anything cool apart from the tv remote, using this?

great hack! Just to let you guys know that it worked for my Logitech Quickcam Messenger (this cam is not supported at all under Linux, so it’s quite useless for me :p ). I’ve “blinded” the camera with two layers of non-exposed and processed color film. Althoug the focal point changed drastically it was easy to refocus (by moving the “screw”). Very nice, congrats!

Gave it a shot on an EasyCam Pro (model: ho98064) and it works! The IR filter is square and pops out if you break the circular piece of plastic around it. I used superglue around the edges of two squares of exposed film to replace the IR filter and whallah! Of course, I lost the install CD for the cam so I didn’t know it worked until I found the drivers. They are a bitch to find, by the way. If anyone else needs them, follow this link: http://www.jascoproducts.com/computer_software_cams.html

It’s interesting to see which lights give off infrared and which don’t. The sun obviously does. My cell phone doesn’t. Regular light bulbs do.

A bit of trivia. Army NVGs can see low light as well as ir and they have a little ir lamp on them to help see in total darkness. Sometimes people would forget to turn the lamp off and you could spot them from quite a distance.

The heating elements in toasters are basicly just like light bulbs for infra red ( http://pfsoup.blogspot.com/2005/06/glod-in-infra-red.html ), so a possible light source, might be warm though.

If you have a Logitech Quickcam Express, as I have, there is no need to modify it, since it already shows IR light. Just point your TV remote or any kind of remote at the camera and you will see a white light that isn’t visible to our eyes. Magical!

Can anyone confirm whether this works with “Logitech ClickSmart 420″ or “Logitech USB ClickSmart 310 Dual Cam” ??

do somebody had done images with the visible light filter (exposed film)? I need a vision system that allow me to only see the objects illuminated by the IR light in a day light ambient.

Does anyone know how to do this hack w/ a creative webcam pro? The IR filter is circular and between two other lenses…
Any help would be greatly appreciated

Sounds really cool, I tried it and I ruined one webcam I think a stupid Qcam which I found in the garbage and while trying to separate the lens and a rubber ring with a knife I cut my finger and I can see the bone…
So I’ll call it a day and I’ll retry it tomorrow

i mean is there a way to do it without an image intensifier? i can afford one, but am just wondering if i need to spend the money/time

ok ok ok…how about instead of bothering with all this crap…you take a camcorder…and put it in night shot…ooo wow look you can see infrared….how amazing

Ok well….Great point actually

Errr.
Excellent and all that.
But im an idiot and somehow managed to do this by ACCIDENT.
my webcams really cheap and doesnt even have the brand written on it.
anyway, one day i was using it and noticed that half was kinda, doubled up and light in the corner. thought something was stuck behind the lense and took it off.
the IR filter mustve fallen off because when i shoved it back on my camera is now IR all the time!
Took me a week to figure out what happened heheh. anyone know how to get some sort of filter back on so i dont look like a scary albino all the time?
thepirateferret(at)yahoo(dot)com
if anyone knows.
cheeers.

Bought a cheap ClickSmart 310 dual cam just to see what it was. It worked ok with QC Express drivers – so go figure.

But image quality was worse than expected – soft focus and flare. Disassembled and discovered that one side of the IR filter had a fine-textured pebbled surface (excess glue?) After replacing with black film squares, the images are … strange … but much sharper.

The 310 is fixed-focus, however, it looks like the designers provided an option to assemble it as adjustable-focus. If you can break through the locking glue without damaging the lens barrel, and if you then snip off a tang and add a drop of glue to another location, it still looks stock, but is adjustable.

You can also use the metal-coated plastic that is used inside a floppy disk.

I used a microcamera(http://imagenes.solostocks.com/media/4/8/2/media_1361284.jpg) & with a hole punch i cuted film to create the filter. Isn’t necesary to glue the filter because it fits perfect apliyng a little pressure (like it were a rubber plug). only takes 4 min.

But i cant see it working :)
