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. Link (via Make Blog)
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
