Cool beans !!
Plastic quarters for your coin door.
I don't know what else to call what I am going to show you.
As you Stern lovers are aware, there is no Free Play. So you either set your pin to award a game at 10,000 points, or you open the coin door and manipulate the wire on the coin switch, or you attach a door bell button to your cabinet, or you solder on a push button switch and leave it swinging by the wiring inside the coin door, or you keep a pocket full of quarters handy.
None of the above counts as plug-n-play. There is always something you have to contend with to add credits to your classic Stern. I call it a hassle-factor.
This morning I thought of something that might work better than all of the above. This afternoon I got it done. Up and running. I think it is pretty cool. A no-hassle way to add credits to your classic Stern.
Pics tell the story.
You need a mini-micro switch. The momentary type with a lever actuated push button. You need an alligator test lead cut in half with a clip on each end. Some shrink tube. Some polycarbonate. And some thin-bodied fast setting super glue. And some 3M super sticky double-backed tape.
It works like a charm.
You need to remove one of the coin chutes from the coin door. It is attached with 4 machine screws.
The black nub you see on the strip of poly will be the "button" that will actuate the lever on the micro switch.
It will fit into the slot in the coin chute.
Wires are soldered onto the micro switch.
Checking final fit of poly strip inside the chute. Nothing is binding. In my best NASA voice, " Everything is A-OK".
The two halves of the chute have been taped together to hold everything tight. The micro switch has been located into the best fitting position and locked on with some super sticky 3M double backed tape. Lightly pushing on the operating end of the poly produces the desired results of actuating the micro switch.
The coin chute has been reinstalled to the coin door.
Here is the front side.
Front side with me giving my new "button" a push. So far , so good.
I have trimmed some of the excess poly from the "button" to add some refinement. I am going to trim this a bit more and into a crescent shape so very little of the "button" will be showing.
The two alligator clips have been clipped on to the coin door switch.
As I said earlier, it works like a charm. I know a pinsider with a 3D printer. I'm going to see if he can print me up some of these plastic "buttons" because I want do all my Sterns this way.
Would anybody be interested in some of these if I can get them printed? I have no idea what they would cost.
