18.04.2012 - Make a wide spectrum camera at home
(Note: Much better write-up of this is now available at Ribbonfarm: https://www.ribbonfarm.com/2016/05/12/artem-vs-predator/)
Let's say you want to make a camera. A digital camera to take pictures in any spectral band.
No CCDs, no car-priced thermal IR matrices.
It may not be perfect, but it was worth the effort.
The camera described here can be made out of low-level components - a photodiode, some stepper motors, an obligatory Arduino and a wooden pinhole box.
