Vintage Pinball Repair Modernization Update: Williams Little Chief Pinball Part 2

Part 1:    • The Saga of Little Chief: Timmy's Wil...  
The Saga Of Little Chief Playlist:    • The Saga Of Little Chief  

Timmy continues his slow but tedious work on the Little Chief pinball machine. He gets the playfield partially working for some simple testing/flipping for fun, cleans some of the features, and replaces some rubber. Then, he does some experimenting and learning on a (knockoff) Arduino Uno. Later, he reworks the chime unit and builds some prototype mosfet transistor control boards and successfully tests the chime unit. Finally, we do some wiring on the playfield and test the 50 point switches along with the partially reinstalled chime box unit.

NOTE: We accidentally left out the explanation and design theory of the MOSFET solenoid circuit control out of this video, which was referenced a couple of times. We will be sure to add it in Part 3 down the road! A diagram and explanation of the MOSFET circuit can also be found in the hackster.io link below.
