The Clocksquared word clock, which displays time and birthday messages
The mechanical design files are stored inside the Mechanical Design folder. There's a main assembly file, clocksquared_assy.prt. Each of the individual components are stored in their own folder. Most files have a PDF file available with a technical drawing of the respective part.
There are several source code files. Besides the main wordclock.ino file, there are other Arduino programs available for testing purposes or additional functionality (such as scrolling text).
A full build log of this clock is available at my website. You can also contact me through my website if you have any questions or remarks regarding this project.
