We have open source browsers, operating systems, and other digital solutions, but it’s heartening to see open source also make it into physical products. October’s Scientific American covers the Open Prosthetics Project, a clearinghouse for free new designs for better prosthetics. (Just think of groups of people swapping and checking in CAD files instead of pieces of code.)

All started by Jonathan Kuniholm—himself an amputee from the Iraq War—and his North Carolina firm Tackle Design, the project has generated numerous improvements to the classic prosthetic arm, fixing common failure points partially by working with test patients who take their prosthetic arms to extremes.
Also see the article in Wired, the BusinessWeek post, and the podcast with Red Hat Magazine. And note the Project’s interest in Eric Von Hippel’s Democratizing Innovation, the same dude that’s nuts for another open source approach to physical products, Threadless.
The problem for the Open Prosthetics Project is now an economic one. Through open source they’ve eliminated the cost of design and development, but they still battle the cost of manufacturing an improved design. There’s the challenge for physical product open source systems: after design and development, they still have to manufacture and distribute, something the digital world takes for granted.
