American Girl Pinball Teardown 4: Score display

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.

This is super cool! I would love to learn how to do this.

You can! I didn't know how to do it when I started. These videos pretty much walk through my learning process. Just doesn't show all the Google searches.

Awesome!
