Yeah! I purchased most of the parts back then, but I still haven't built this one.

I did get started with a much simpler visible spectrometer though:

But even this one has a long way to go :p

That's awesome. I too built one with the same grating, a raspberry pi camera, pelican case, and raspberry pi. I want to redo it sometime with 3d printed parts. I was able to get spectra of a bunch of sources. I'll post some pics here when I get back from vacay!
