So you should be able to record IR-light of stars or UFO’s on a camera. (assuming that this light isn’t filtered by the atmosphere.QuoteYou must be joking right?
Stars give off light (or rather, radiation, if you want to be technical) in the entire electromagnetic spectrum? Why wouldn't they show up on a video?Ok, I'll bite...
First of humans can't see the entire electromagnetic spectrum, only a small portion of it. Electromagnetic radiation that people can see is referred to as (surprise-surprise) visible light. People can't see IR (Infra-Red) because it is not visible light.
Second of all even if humans could see IR, IR images would not show up on a photograph, film, or video unless the film or video recorder were sensitive to it. There is no point in goingto the expense of making video recorders that are sensitive to IR because nobody would be able to see it any way.
Thirdly, even if people could see IR and all video recorders could record it there would still not be very much to see because the earth's atmosphere filters out almost all of it.
Wikipedia - "The principal limitation on infrared sensitivity from ground-based telescopes is the water vapour in the Earth's atmosphere, which absorbs a significant amount of infrared radiation. For this reason most infrared telescopes are built in very dry places at high altitude (above most of the water vapour in the atmosphere). Suitable locations on Earth include Mauna Kea Observatory at 4205 meters above sea level, the ALMA site at 5000 m in Chile and regions of high altitude ice-desert such as Dome C in Antarctic...."
Astronomers are able to make IR images visible to the human eye by using false colors (i.e. frequency shifting IR image into the visibe spectrum). You can click here to see a false color IR image of the Milkyway captured by the Spitzer Space Telescope.

Thanks Mr Ooze-ee-air! It'll have to be USB stick sorry bud, your all new car will have to rely on YOU for said SDLet me know if you need PAL or NTSC!!!
NOTEAGE: Okay, maybe even a commentary on the USB too
Quote from: ProgZmax on Mon 01/06/2009 20:44:45Of course you can - there has been an incredible invention callde the power toggle - on your speakers (if you have those small active ones) (or, as in my case, on the old stereoset beside my PC which I use for sound), if that won't work, you could always pull the plug out from your PC's sound card. Of course, this won't guarantee you will be able to follow the dialog at all, since maybe they don't have those "old-fashioned" lines of dialog floating above the heads of the characters.
As long as I can turn off the voices to avoid Dominic Armato's incredibly annoying nasalspeak I'll give these a try. I'd rather play them with just the text, anyway.

I promise I'll keep up on the maintenance schedule, regular oil-changes etc. I'll even polish them up for you before the hand-over, put them in a shiny new envalope (I can afford all the new envelopes I want, even ones with diamonds ruond the edges - once I'm done winning the lottery).Quote from: The Ivy on Thu 25/06/2009 00:42:30
