Michael emailed me with the link to his latest project. This is what everyone in my dorm at MIT dreamed of owning: an NTP-enabled analog panel clock!
NTP stands for Network Transport Protocol, and is how the Internet (and anything connected to it) knows exactly what time it is. By using NTP servers for updates, the clock will always be perfectly on time – useful when there’s a blackout.
The clock is powered by an Arduino. To connect to an NTP server, an XPort shield & XPort direct is used. The three analog panels are driven by the PWM channels and are tweaked by some analog circuitry on a proto shield. Theres great documentation, including code, schematics and diagrams so there is no excuse to not build one for yourself!
