Please note: This is a companion version & not the original book. Sample Book Insights:#1 I had a lot of fun with radios. I started with a crystal set that I bought at the store, and I used to listen to it at night in bed while I was going to sleep, through a pair of earphones. One night my mother and father came home from a night out and very, very quietly took the earphones off me. The radio blew a fuse, and the bell went off with a helluva racket.#2 I built an amplifier for a photo cell that could make a bell ring when I put my hand in front of it. I bought radios at rummage sales. I didn’t have any money, but it wasn’t expensive. I would fix them and then sell them.#3 When a person has been negative to you, and then you do something like that, they’re usually a hundred percent the other way, to compensate. They’ll usually tell everyone how great you are, and how you fixed the radio by thinking.#4 I have a puzzle drive that explains my desire to decipher Mayan hieroglyphics, or open safes. I was always known for solving puzzles in high school, and I continued doing so at MIT.
