Open Source Hardware (OSHW) is a term for tangible artifacts -- machines, devices, or other physical things -- whose design has been released to the public in such a way that anyone can make, modify, distribute, and use those things. The official version of the "Open Source Hardware (OSHW) Statement of Principles and Definition v1.0" has now been published. This publication can be seen as profound and game-changing as the original "Open Source Definition," created by Bruce Perens and the Debian developers as the "Debian Free Software Guidelines" in 1997.
