Looking in my drawer of old prototypes, I found two early attempts at a generator-mounted voltage regulator for my Harley Sportsters (Fig. 3). I started out using plated “pegboard” PCB material.

Grinding out copper is one way to create a printed circuit board, and low-cost CNC milling machines have improved to the point where it’s possible for many.

Now the printed circuit board (PCB) made by Steve Jobs to procure that original order of computers in 1976 is up for auction. It's labeled "Apple Computer A" and was hand-soldered by The Woz himself.
