Infrared Light: Raspberry IR Camera and cheap Spectrometer (i-Phos)

We Makers often use infrared light for their projects. Its main advantage also makes it sometimes hard to work with: It is not visible. This is what we will change today. We will measure its spectrum with a do-it-yourself spectrometer and build a wireless IR camera using a Raspberry Pi.
