The Bongo guy is Dean Cuadra of Santa Monica, California.

I make my living in electronics.  My mother tells me that I became fascinated with electricity as a rug rat, when I stuck a paper clip into a wall outlet (they hadn't yet invented baby-proof outlets).  The shock didn't scare me away from wall outlets--  it just made me want to learn about what comes out of them.  A few zillion electrical shocks later, I think I'm starting to get the hang of it!
