I have recently aquired an old Emergency Radio (Very Outdated) with a built in PIR motion detector. Instead of trying to bring it into the 21st century, I'm just going to salvage it for parts.
That's when I had an idea by which to turn the PIR into a Thermal Imager.
Since it has a wide viewing angle and works by sensing the average change in infared light coming to it, by employing a scanning barrel would it be possible to turn it into a compact imager?
I have seen it done before using a Parallax and a Nipkow Disk (link Below), but this method is not very streamline and fragil. Also a computer is required to make sense of the data. I want something that can be mounted onto a moving platform, with analog composite outs.

Perhapse this could make a great show challenge.
Anybody have any suggestions?
