Quoted from xfassa:

It looks fairly straight forward. If Scott has no future plans to produce and if he wouldn't object, I would be willing to make a set or two. Mainly because BOP is on my short list. I could design/print the bracket and most of the parts can be sourced from PinballLife. I would need a little more info on the circuit connections (haven't looked that closely). Also, I would just use an off the shelf hobby electronics board (far less elegant than Scott's professional board). Look like a fun project.
