build a thermal imaging scanner with low tech materials

The author uses a camera, arduino, a couple of servos, and a cheap temp gun to map out the camera image for thermo signatures.  Its slow, but its pretty nice overall image (the thermo is overlayed onto the camera image).

Heck alot cheaper than a thermo camera.  Cheapest of that I have seen is 200 dollars.
