Sawomedia is the winner of the Seeedstudio Rainbow Carnival 2010 design contest. The winning entry was a RGB coffeetable using a handsoldered 64 Superflux Pixelmatrix and the Rainbowduino LED driver platform. It uses a 9V PSU, but can also use battery power. The supporting structure is made mainly from recycled materials.
Seeedstudio is also a source for the Open Bench Logic Sniffer for $50, with free worldwide shipping.
