In the spirit of regular folk turning their back on industry and making stuff themselves, two things:
1) The “open source hardware definition” is now an official thing. Phil Torrone of Make Magazine (quoted on Boing Boing): “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 definition provides a standard for for developing open source hardware licenses. What does it mean? I don’t fully know. But, I guess it provides a format for the guys in part 2) to distribute their designs.
2) Open Source Ecology is a project set up by a group of engineers, farmers and others to design and build (on an open source basis) a set of tools that would allow a small group of people to create a sustainable community from scratch. This is the Global Village Construction Set. Watch the video, and then think about getting together a few friends and $20,000 and going to live in the wilderness.
