I think I've figured out how to program the radiation collection, and writing aspects of the program. Considering I don't actually have the data writer shield, nor the radiation shield I can't really test the program, but I'll try to get some time this week to start writing the code.
The thing I'm having a bit of trouble figuring out is the power requirement. I've looked on both websites you sent me, and don't see anything about the power they draw, nor the weight of the components. They do mention that with the backlight it draws a current of 21 mA, if that helps..
