Thermal imaging on the cheap

Stephan Martin writes in to tell us about his homemade thermal imaging system, the Thermoscanner. He mounted a TPA81 thermopile array onto an XY servo mount, then hooked it up to his computer using an Arduino microcontroller. A Processing program is then used to collect data from the sensor and display it in an image.

The resolution is pretty coarse, but it is pretty sweet to be able to make thermal images for around $150!
