Well, it looks like I won't have boards in hand until the 25th or 26th, which means I can't use them as a prop in my quarterfinals video. 

OTOH, I'm forging ahead on the documentation front. I just checked in a system description document that covers the overall intent and the hardware design. 

I realized that to make a really good impression on the quarterfinal video, I need to have some nice wireframes of the proposed app. I'm not any great shakes at that (and I'm still working on finding a software collaborator), but I think I can hack something out in time.
