American Girl Pinball Teardown 6: New adapter PCB

Reverse engineering and customizing "The Flip Side", a 1:5 scale pinball machine created by American Girl (the doll company). This is the 6th video in a series where I disassemble and reverse engineer this cool little machine. In this video we connect the machine to a Teensy microcontroller using a custom printed circuit board (PCB) and control the playfield lights and backbox score digits.

Did you actually finish this project in the end, like getting the switches, etc. functional?

[@kyle5574]

Still working it! Switches are working. Sound is going to take a while. After that, I think I’ll have everything I need to get the machine functional with new code. Then I’ll have to figure out where to put the new microcontroller-it’s much bigger than the original.
