Instructions Included

http://www.instructables.com/

I am addicted to this site.  Bored at home?  Slow at work?  Waiting for your friends to get ready to go somewhere?  Pull this place up and LEARN something.  While writing this, your author has learned how to make a forge from a torch and a can of beans, a set of beads to count kilometers while walking, and a “Boba Fett” helmet from old carboard. 

Practical, outdoorsy, or frivolous, Instructables is a great site for accumulating info and ideas no matter how much of it you actually make or use.
