Thanks for the coverage Caleb (by the way my name is Charlie not Chris). I've added a number of new features and I'm in the process of doing battery life tests, so far it is lasting longer than expected.
That's a nifty little board and the layout is very pretty -- something you need if it's going to be displayed like artwork. What I'm wondering (but not enough to follow the link right now) is how to set all those modes with just two buttons? Standard cheap clocks are hard enough with two buttons, and they only have a couple of modes.
