I am not that experienced with hardware so Arduino seemed a no brainer for me

I am quite interested in that (assuming you are talking about halogen sources) - would you point me in a right direction?

I had the chip assembly left from experiments with SLR/n nonlinearities in the last 1/6 stop (we discussed it a while ago if you remember) so it was an easy choice.
I had extracted my ProBack spectras tonight and they are rubbish. The first attempt went astray so I will need to redo it. I'd need to correct a few things as well:
- I used Kodak firmware capacity to subtract black on long exposures but it still generates a lot of noise so will need to do black subtraction myself
- have not closed viewfinder (I know its stupid but I forgot) for the 400-450 range so blue is captured quite badly
- I need to invent something to connect camera to integrating sphere more tightly to prevent even slightest leaks
- And add baffle to either entry from monochromator or photodiode (the latter seem to be influenced a bit by entry light positioning and sits opposite exit from monochromator albeit offset a bit).
