Qi hardware is a 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. The project is both a community of popular open hardware websites and a company, co-founded by Wolfgang Spraul and Yi Zhang, that makes hardware products. Originally formed from the ashes of the Openmoko project, several key members formed Qi Hardware Inc and Sharism At Work Ltd.
