Have you ever had the desire to see what can not be seen? I never had the ability to see in thermal infrared, and it is rather cool to be able to see in the thermal infrared part of the electromagnetic spectrum. Unfortunately, most thermal (FLIR) cameras are very expensive. In 2011 cameras frequently cost several thousand dollars. This project was created to develop a cheaper solution at a fraction of the cost.
The primary reason for the cost difference is the thermal infrared sensor. Instead of having a 2 dimensional array of sensors, a single sensor is moved in a raster scan pattern. Moving this single sensor takes time. So while you have fewer costly sensors, it takes longer to take a picture. This means the camera can not take images of moving objects, and the objects have to be very still during the scanning.
The original instructions can be found on my web site http://www.centralnexus.com/thermal/. These instructions require some soldering ability. It can take most of your weekend to assemble this camera once you have the parts. If you’re good with soldering you may be able to assemble it faster.
