Read the excerpt from "On Becoming an Inventor" by Dean Kamen.Then Bart went off to college and I had use of the rest of the basement. I stopped doing photography and became interested in electronics. It was the early days of disco, when making music and light shows was the rage. Everyone wanted to buy a box that could connect to their stereo to create new light and sound effects. I started building boxes after school, buying components from a nearby Radio Shack, and reading up on electronic recipes for building loaders in the basement workshop. I began buying voltmeters, soldering irons, and other tools for making light organs to sell at school and in my neighborhood. I made enough money to stock more and more equipment in the family basement.
