For those eagerly waiting for info on this project here is a small update.
The PCBs arrived today for the interface board that senses when a game is in play and then delivers power to the shaker driver board - in the pic below you can see where it mounts in the machine (the initial "home made" prototype board) and the following pic shows the first one made up but missing a few connectors and resistors (parts we are waiting on delivery).
This is a function I had overlooked during the initial design as I was mainly looking to incorporate the shaker in Homepin pinballs so this add-on kit is a bit of an afterthought, this extra board isn't required in our pins (or Sterns with shaker code either).
We are getting there.....
