Simple IR Camera From an Old Webcam
(1/1)
Nothing:
I remembered reading a while back about how all digital cameras can see into the IR but are limited by an IR filter they put en the lens. So tonight, I dug up an old webcam, took it apart and removed the filter. Had some trouble getting it back together, so it's not the prettiest looking thing, but it does the business. Here's a demo of it in action:

hmmmm wastes 1:57 mins of my life, coz I stopped watching the video after that.  |O Check this https://www.theengineeringprojects.com/2018/08/esp8266-pinout-datasheet-features-applications.html

I did this a while back but installed some old photographic film to block visible light. It makes some things look weird in particular, but mostly underwhelming.
Nothing:
There are some interesting videos of various things that are opaque in visible light but transparent in infrared. Bromine was one that I found surprising. Or there's the classic experiment where you can see through a garbage bag in IR. That's a good idea about blocking out visible light, though. I'll have to look into that. I'd really love to have a pure IR camera that doesn't cost an arm and a leg. Did you just put the film in front of the aperture or something? Or was there more to it?
Rerouter:
Some of the more interesting things you can see with an infrared luminance camera is clouds and plants, for a lot of small leafy plants you can see in the camera how healthy they are from much furthur distances than visable light, Equally I think I remember ripe mulberries having a very strong contrast compared to the plant.

For clouds, you can see the water that is not normally visible.

Slight downside is UV leakage, and you do need to refocus it, as the focal distance changes for different colors.
