I saw that the person who developed this device is looking for academic partners to take it further: https://www.sciencemadness.org/whisper/viewthread.php?tid=15...

It seems very well developed. The open source RamanPI [1] got some traction here a while ago. This looks like it may be more costly than RamanPI but it also is more thoroughly developed.

The original RamanPI project looked interesting but doesn't seem to have gone anywhere after several years, unless I'm mistaken. If there's any actual data from it, I couldn't find it.

On the other hand, Luc's results are drop-dead awesome: http://www.thepulsar.be/article/some-diy-raman-spectra/
