In Sum:
I've been engineering high-end high-tech products and in-house equipment for 25 years after being a technician for 12 years. I started professionally when I was 15. In 1972 I was building radios and test equipment with circuit boards that I etched myself. My first radio project was a crystal set I built in 1966. It all started when I was four; I cut the cord on my record player. That started a running fascination with those little blue guys who were dancing across those school scissors with which I hacked through the cord.

I'm still fascinated...
