Regular spectrometers and infrared video cameras cost a lot of money. With a little effort, and a certain camera module for the Raspberry Pi, it is possible to build both an inexpensive Spectrometer and an inexpensive IR camera. The spectrometer is easily calibrated using light sources with known characteristics - for example a fluorescent light bulb has an emission spectrum governed by the mercury vapor in the bulb, which can be used in calibration. For the IR camera, the presenter found a cheap IR camera module that connects to the Raspberry Pi camera port, and then used Motion Eyes to view the video stream.
