Qi hardware

Qi hardware is a defunct project which produces copyleft hardware, in an attempt to apply the Free Software Foundation's GNU GPL concept of copylefting software to the hardware layer by using the CC-BY-SA license for schematics, bill of materials and PCB layout data. The project has been both a community of popular open hardware websites and a company, co-founded by Wolfgang Spraul and Yi Zhang, that makes hardware products. Formed from the now defunct Openmoko project, key members went on to form Qi Hardware Inc. and Sharism At Work Ltd. Thus far, the project has released the Ben Nanonote, the Milkymist One, and the Ben WPAN wireless project to create a copyleft wireless platform. The examples of Qi hardware projects are the Ben NanoNote pocket computer, Elphel 353 video camera and Milkymist One video synthesizer.
