Out of every single RU-vid search result for a DIY pinball machine this one is the best. To me the most complicated element of building a pinball machine is the flippers and how you've done it is so straightforward yet so perfect (especially with regards to the ability to control the speed of the flippers). You sir are a proper genius! Thank you for posting. My only question is whether you ever finished it or not? I'd love to see the final product. I know this video was posted six years ago but if you every did finish it please show us. Even if it's just a few pictures.
