1969 Seven Up EM to Arduino Conversion

- This is just a compilation of pictures and video that I had for the EM to Arduino pinball project that I did. I didn't get all of the work captured, but the machine works 100%. This was a process that took me several months working a few nights a week for an hour or so. I actually did this prior to getting and fixing the Elvis pinball machine.
This started as a play-field that I picked up for $75 and morphed into this finished product. I had wanted to do an Arduino conversion and this made sense considering that the original cabinet was trashed.
This is driven by an Arduino Mega 2650 REV3 and the sound is going through a SparkFun WAV Trigger board. The complete Arduino code is too long to paste below, but if anyone needs it just leave a comment with your e-mail address and I will send it too you.
very cool...
This is great! I'd be curious of a couple details.. like what hardware did you use to trigger the solenoids? And.. is the arduino responsible to trigger the pop-bumpers, or do they self-trigger when the spoon switch is closed, and the arduino just monitors it for scoring? In the original SS boards, those are typically directly triggered to avoid delays in the software. Curious if that's a problem at 'arduino speed'.. I think it would be REALLY cool to make an arduino based replacement for original MPU boards..
I can't speak for Richard and what he used in his project, but the Arduino is easily fast enough to control and trigger the bumpers as long as you keep your code "clean" by avoiding delays wherever possible. To trigger the solenoids I use either relays (for the slow stuff like drop targets and ball releases) and Mosfets for the bumpers. Take a look at my projects if you're interested :)
