I have considered myself a "car guy" for the past 40+ years. About a decade ago I realized that to be a car guy these days, one must have at least a working knowledge of electronics & electrical (aka digital & analog). I bought a Radio Shack basic electronics book, a bread board, some proto boards, and a fist full of resistors, capacitors, comparators, op-amps, & 555 timers, etc. It's been quite a journey, but now I work with surface mount components driven by PIC microcontrollers that I program, touch screens, and some other awesome stuff.
