jareklupinskiAfter some back and forths with designing the case, I realized that it would be much easier to produce the device if I re-engineered some of the sticking points around the previous design. So I cleaned up the entire back of the circuit board so that it can sit flush up against the housing. I also added a trackball for faster and more accurate navigation.

Very neat PCB design.
Perhaps I overlooked something, but I can't find the part number of trackball you used. It's really tiny.

Thanks! I prototyped using this https://www.sparkfun.com/products/9308 and bought a bag of like twenty of them on ebay for ten bucks or something

I that a lipo under the display?
Are you sure? yes | no
broken_display == blown_lipo :) I don't see any other chance for it to be powered.
Are you sure? yes | no
yup, the proper case will have recesses to hold and secure the lipo and screen. it will all be on the inside of a sealed transparent case, so youd have to hammer pretty hard to break it :
Are you sure? yes | no
sometimes LiPos just bloat, so when this bloats, it might crack the display. Al least that was my thought behind that sentence. Cool project though :)

TagConnect! How do you like it? I haven't yet taken the plunge, but it seems like a great solution for Atmel ISP and others.

It's not bad for when you really need it, but I wouldnt replace a good ol' 3x2 shrouded header if I have the board real estate.
Though if you're doing volume production, it does make a convenient pogopin test point array
