Using pinball score reels as wireless displays

[Scott] put together a system where he can use pinball score reels as a wireless display. As you can see in the video below, the result is really neat. The sound alone makes this shoot pretty high on our “things that are cool” radar. The display required 24V AC to operate the solenoids that actually let the display rotate, but he found that an 18V DC supply would allow him to fire a single solenoid. No problem, he just staggered their operation. This is barely perceptible due to how long it takes for the mechanical part of the spinning to occur.

You can download his Arduino sketch and see more on his site. He has big plans too, he just got 4 more of these to add once they are cleaned up.
