This all sounds kind of lame compared to the other comments, but you asked: - Converted a car to electric drive when I was 20 - Was a contestant on a reality show pilot that aired on Discovery - Built a motorized rotisserie out of two old bicycles to cook ~100lb of lamb for my friend's wedding - Built a weight-controlled electric longboard (3wdm.blogspot.com) - Built my own Mazda 323 GT-R (not sold in the US) out of imported parts and a US-spec AWD Protege - Gutted and renovated a 1914 house, including all wiring, plumbing and heating, not to mention stripping eight layers of paint off of every last bit of the original woodwork and windows. Although countless other people have done it before me, I most proud of the last one. A project like that completely takes over your life. I was working to the point of complete exhaustion on it during every moment that I wasn't at my day job for well over a year.
