Getaway Pinball Tachometer Mod 3: PCB Development

Design, implementation, and integration of an automotive tachometer modification for my "The Getaway: High Speed 2" pinball machine. This is part 3 of a multi-part series. Part 1 described the concept, circuit design, and multiple phases of prototyping the tachometer control circuitry. Part 2 described integration with the circuitry of the pinball machine. Part 3 describes schematic and printed circuit board (PCB) development using the DesignSpark PCB software application.
