Yes, I'm still trying to work out the best way to build a cheap (non astronomical) spectroscope...

Why not just use a difraction grating and a web cam? All the interfacing and hard parts are done for you.

You could use a flatbed scanner too. These calibrate at start and end of scan against black and white strips; this would likely need to be emulated.
