I have made a 16×8 led word clock, a rectangular one. Break from square or almost square ones. This one is a complete modular design and can be scaled up or down in size / complexity according to ones need. The whole design and requisite files are in open domain and the project has also some good 3d pcb renders. The main clock controller is arduino-like and is again scalable.
The LED panel is composed of 8 individual panels of 4×4 LEDs. Each group of 4 such panels will be controlled by a MAX7219. Here are the schematics and board layouts of the 4×4 LED board and LED driver … They are on the way to a fab house….In the meantime I shall do 3D render of my project. Schematics & PCB designed using Eagle CAD 6.2.0 Lite Running on Linux Box.
