Open Source Hardware documentation for the Bulbdial Clock:

Source code: standard firmware (updated 8/2010, 33 kB .pde file) (Designed to run in the Arduino environment, version 0023.)
The standard source code makes use of the Arduino DateTime library, which you will need to compile it.
An updated version of the source code, to run in the Arduino IDE version 1.0, using the newer Time.h library, is now available here.
To set (sync) the Bulbdial time from your computer via a USB-TTL interface, use the "SetArduinoClock" Processing sketch, available here. Run this sketch with Processing.
Also available: "Hello Bulbdial" demo code, in Arduino .pde version or "straight" avr-gcc version.
Electrical schematics are here. (125 kB .pdf file)
The circuit board design is in gEDA, and you can download the design files here. (200 kB .zip file)
The standard case design is available here. (50 kB .pdf file)
