Best of luck with the project. I think the really good idea is the open-source spectral library. You need to educate your readers a bit more, though. They need to be aware of the kind of spectroscopy the machine does, i.e UV-Vis, and what information it provides. I might try DIYing it, but what would be really interesting is an IR spectrometer, under 250$. Tough.
