  • Pitter: This camera picks up near infrared, around the same wavelength as that emitted by the IR LEDs mounted on it. To see the heat of a human body, you’d need a camera that’s sensitive to far infrared of much longer wavelengths. That’s why those FLIR cameras are so expensive, a regular CCD isn’t sensitive to the right wavelengths for such cool blackbody radiation.
    However, you could pick up the light from something that is slightly cooler than “red-hot”. For instance, fireplace embers will appear to have a larger “hot” surface than they do to the naked eye.

No public wish lists :(
