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.

    I jus did a search on eBay for a geared motor.

    Look for something I between 10rpm to 15rpm, ideally 12rpm

    Well, I made use of the 12v supply so 12v would be a good place to start. but as it's normally a dc motor that is driving the gears then 12v-15v will do.
