Comment Liquid Fuel Rocket Engine (Score 1) 535
I'm working on a regeneratively cooled LOX/Kerosene rocket engine.
When I was 15, I built a Z-80 computer from my own design. I entered it in the science fair but the judges thought it was a kit so it got disqualified. I guess I did too good of a job wire wrapping it. I'll never forget the experience of hand-entering the bytes for my "operating system" into the EPROM burner at the local computer store. Needless to say, it didn't work the first time...
