3.3v is what it looks like everything is coming down too, the case I am working on will most likely not have enough room, but the battery is now a non-essential and future revision. Now is 3.3v going to limit the usability of the device? many sensors (such as the parallax PING sensor) require 5v, and a ping sensor would be very handy on this watch...
Anyway, again revisions are made. The jumper solution hit me square in the face today... The breadboard I want to test... IS THE JUMPER LOCATION. Make the board bigger, house 26 pins in that small rectangular space and BAM! everything is solved.
I spent this past day working on the band, nothing special, but sturdy. It's 4mm thin, and 40mm wide. This is the smallest, lightest, and cheapest ($20 to fab) version yet. I still need to get a model fabricated to see what my true limits are, for all I know the band can be 1mm thin.
Again another picture of the revision, this thread is nowhere near dead...
