Here's my first prototype, constructed September 18/19. (This picture is from 5:23 AM on Sept 19.) I didn't actually use the Patch Shield for this one; it was just still on there from when I put the kit together ages ago. The DS1307 breakout board is connected by means of micrograbber jumper wires. I carried this home and then back to Protospace on the bus and surprisingly didn't get many weird/curious looks.

When I made this, I ended up staying awake for about 25.5 hours (not all prototyping, obviously), followed by sleeping for almost 21 hours, which is probably the longest I've ever slept. (Which is weird, because I used to make a habit of staying up for 24 to 36 hours and never slept for more than 15 hours before this.)
