Clock

The clock I'm building is a massive led powered clock based off of schematics and a pic microcontroller. Arduino.

Router Interface

The clock interfaces with a Wrt54gl for time updates, twitter commands, and vpn connectivity.

• get-twitter reads the @replies for relevantclock for commands, parses them, and sends them to...
• clockctl reads in commands and interfaces with the serial port.
• send-twitter can send out updates.
