Make a programmable binary LED watch
Instructables's 01 watch is a DIY binary watch where you solder on the LEDs and program the chip with a flexible firmware that includes "a voltage meter, binary counter, club mode and time display. The watch is fully programmable. Future firmware upgrades will include: stopwatch/timer, alarm, bicycle speedometer/odometer, data logging, and an advanced configuration menu." They briefly mention the possibility of a watch that displays the seconds since Unix epoch, which is what I really want, especially if it can do so in hex. - [Boing Boing]
