Word Clock (not World Clock)

"It is ten to eight"

Made with a Diavolino (from Evil Mad Scientists Laboratories) and a LolShield (from Jimmie Rodgers), a piece of paper with carefully crafted mirrored printing, and a recycled solar garden lamp enclosure.

A good way to learn how to tell time in French...

The Diavolino has its own crystal, which makes it one of the few barebones Arduinos that you can actually make a relatively accurate clock out of. It's also one of the cheapest around. Thank you Wendell!

The LolShield uses "charlieplexing" to drive 126 LEDs with only 12 pins...

Setting the clock still requires a serial port.
