When I was in jr. high school (8th grade), I also had an extremely gifted and talented friend who would bring little electronic gizmos to school. I remember flashers, beepers and a pill bottle set up to shock people. Kids in our boy scout troop called him "Mmmm Buzzz Click."
We'd be walking though the school hallway and he would stick out his hand with the shock bottle toward someone and say: "Here. Hold this." Anyone who complied, of course, got a nice little shock.
One day he was talking about an oscilloscope that he had made from an old TV. When I asked him how he knew how to do all of that, he said: "I don't know. I just know." To this day I find that a fascinating answer.
Sadly, brains weren't all that well respected in the little logger town I grew up in.
