LightPrint

LightPrint was my Final Project at the University of Victoria. The goal was to create a small inexpensive detector of greenhouse gasses. LightPrint operated on the basis of spectroscopy. Light from a selection of wavelengths would be combined and directed through a prism onto Photodiodes with different peak wavelengths, moving the spectra across the photodiodes allowed us to look at absorbed light and determine concentrations of gasses.

In 4 months we had a custom PCB which was able to detect the peaks of the wavelengths of light generated by the diodes and was able to draw a spectra on a graph.
