My first book project began in 1998, titled Lessons In Electric Circuits, and I didn’t call “quit” until six volumes and five years later. Even then it was not complete, but being an open-source project it gained traction on the Internet to the point where other people took over its development and it grew fine without me. The impetus for writing this first tome was a general dissatisfaction with available electronics textbooks. Plenty of textbooks exist to describe things, but few really explain things well for students, and the field of electronics is no exception. I wanted my book(s) to be different, and so they were. No one told me how time-consuming it was going to be to write them, though!
