Sounds fun. Might want to call it openspectro. There are lots of different types of meter.
In terms of the competition, I worry about lack of need for a mobile power supply, unless we can get this thing carry-able? Also what is the light source?
We could also think about if we can make cheaper cuvettes somehow. I'm thinking slides and hot glue (as long as the light doesn't shine through it, it should be okay) --Eb4890 10:59, 7 March 2011 (UTC)
