A year and three months ago I built a shuffleboard scoreboard using a 21 position mechanical stepper to switch lamps behind computer generated number transparencies. I had since gotten another order to build another one. I can't find large LED seven segment displays along with the driver. Most require interface with a computer and I can't keep the price down to about $300 which most people will pay. Here's a picture of my finished scoreboard.
Nice Scoreboard! Not sure if any of the following links will help you out, hopefully so. The last link is for a bunch of manufacturers that may also have something. Let us know if you find what you need.
