Driving LED matrix with AVR on glass board

Driving LED matrix is one part of the story. Everyone basically can do this. But how about circuit on the glass. This may take time and some effort. Andrew found this area interesting and started building 2D matrix on the glass driven by Atmega1284. The circuit seemed easy enough to trace on a single sided board.

To make traces he used copper tape which seems to be pretty robust thing to use. Just cut and stick to the glass. To make things faster, Andrew drew circuit and PCB layout with eagle, this way he only had to copy the layout. After copper layout was done, he simply coated traces with solder and soldered the components. Of course it takes time, but end result looks really great.
