My "nerd" friends (I hate that term) are fiddling around with robots and hardware. Stuff like Arduino and mbed. I'm trying to spec out a DYI book scanner robot that can automatically scan all of my old books. But frankly, I don't think that's very nerdy. My blue collar friends that welders and electricians build stuff like that all of the time.
