Dismantling "The Flip Side", a 1:5 scale pinball machine created by American Girl (the doll company). This is the 4th video in a series where I disassemble and reverse engineer this cool little machine. In this video we use a logic analyzer to figure out how to control the score digits in the backbox using a Teensy microcontroller.
