Those of you who are familiar with the Atlas HO Turntable know it's pretty much impossible to find a ready-made solution to add DCC indexing capability. It doesn't support an easy way to add indexing like the more expensive Walthers turntables. But for me, an Atlas turntable was ideal because of its size, so I went with it. However, I wanted DCC indexing functionality, so using an Arduino with a hall effect sensor as a tachometer (installed inside the gearbox) I built a custom DCC control system for the turntable.
It's not totally done yet, because I still have to program the interface to my layout PC (which runs JMRI), but that will be fairly straightforward.
I can post more details if you guys are interested; let me know what you think! I included a short demo video with a little bit of explanation.

You can also read more about it in this post on my blog, and you can view/download/contribute to the code on GitHub.
