Make your own Pong-clock: MONOCHRON

Phil Torrone sez, "Hardware hacker 'Ladyada' has released an open source retro arcade style table tennis for two clock called the MONOCHRON. According to MONCHRON project page they 'wanted to make a clock that was ultra-hackable, from adding a separate battery-backed RTC to designing the enclosure so you could program the clock once its assembled.' It includes a ATmega328 processor (with'Arduino' stk500 bootloader for easy hacking). It's completely open source hardware, all firmware, layout and CAD files are yours to mess with."

MONOCHRON (Thanks, Phil!)

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.

Smoobly

Ever since Tiger came out, I’ve had a Dashboard widget that does exactly this.

Life imitates Apple.

So, how does it change the time at the top of the hour when both players numbers need to change simultaneously? One person gets a point and both scores change?

And of course it changed to 4:20, what other time would they have chosen??
