Nine Ball lamp boards are prototyped. A few months ago when the 555 lamp boards were being made to light up the Big Game bingo cards some of you were asking for something similar for your Nine Ball pin.
I had a prototype set sent to me a few days ago and after some fitting and trimming I got them soldered up an running today. They work nice. Actually, they work real nice.
Since this is a prototype, the board down at the flippers had to be trimmed a bit to fit due to clearance issues with the slingshot brackets; Because of clearance issues with 555 sockets at the 4 ball position and the 5 ball position, the final product will most likely have two permanent white LEDs installed which will allow for this board to fit properly out of the box.
The two boards that live next to the drop target assembly fit nicely and have no interference with the drop target parts. The first two prototype boards that were sent did have interference problems but the second set of prototype boards had this problem corrected.
They were easy to solder up and I had to change a couple of ground wires. But since I was making ground wire changes I went a little farther and added a brass grounding bus.
If you know how to solder they are a piece of cake to install. The two boards next to the drop assembly install to the 4 locating holes the factory boards used. The board between the slingshots has to be located (by you). This is easy to do, but you want to take your time and do a clean job.
I'm going to take this to the Nine Ball board to get an idea of how many will be interested in these for their Nine Ball.
