Antique Weather Clock
An antique clock retrofitted to connect to the internet, download the current weather forecast, and display the weather condition and temperature.
Body
The clock has been stripped of its original mechanism and the face replaced with one that was designed to match the appearance of the clock body. The original hands were retained and used to keep visual consistency.
The face was designed in the GIMP using graphics found on the Internet. The source file and a JPEG of the face can be downloaded below.
Hardware
The clock is run by an Arduino Duemilanove with a Adafruit ethershield (Wiznet) and a Freeduino protoshield which provides the connection for two GWS PICO+ servos.
A schematic for the circuit can be downloaded below.
Software
The Arduino runs a sketch that connects to the Environment Canada website after a set interval, parses the page which is received, and updates the hands accordingly. The Arduino also has a web server which hosts pages to the local network which provides a more detailed forecast and allows the update interval of the clock to be changed.
Three third party libraries were used; PString to handle parsing the incoming website, Flash for memory management, and Streaming for easier coding.
The current version of the sketch and third party libraries can be downloaded below.
