Here are a couple other links to making non-workout stuff I've come across.
Makezine This is a REALLY good zine, primarily covering, but definitely not limited to, electronics. There is a popular torrent covering all the back issues.
Farmshow This is a magazine, (old fashion in the mail type), that covers homemade farm equipment. Farmers seem to be very good at coming up with homemade ideas. I enjoyed looking at the few issues I've run across.
