The Monome ( http://www.monome.org http://www.monome.org ) would be a better example of open source hardware. They provide source files to the 40h with schematics, parts lists and firmware ( http://docs.monome.org/doku.php?id=tech:source_files:40h http://docs.monome.org/doku.php?id=tech:source_files:40h ). The larger monomes are just tiled versions of the 40h. A group of monome users ported the monome to the arduino (I built myself a Arduino-based monome port). There is a great community centered around the monome
