Instructables
Featuring Howtoons illustrations and a lot of handholding, Instructables is a "step-by-step collaboration system that helps you record and share your projects with a mixture of images, text, ingredient lists, CAD files, and more...Show your colleagues how to operate a machine, show your friends how to build a kayak, show the world how to make cool stuff." We like the Pimped Out Megaphone Helmet. Not hardcore enough for you? Try the Metalworking Lathe. Even harder? Dare we link to the No-Sew Disco Gear? [lifehacker]
