Introduction: Earthshaker Sinking Institute
This is another one of my Non description, Pictures only Instructables.
I had a Williams Earthshaker pinball where the Earthquake Institue building was fixed in place and didn't move like in the original prototype. The idea was, that during the simulated earthquake the building would sink into the playfield. To save cost, Williams removed this feature from the game as it wasn't a necessary toy and didn't effect the gameplay. The code and hardware to control the building still existed in the production code so it was just a case of adding the motor and switches.
This is just an instructable on how the mechanics were done.
This is the test run
