Mike, that's the best part of all of this. I have seen the Ross TT at shows and they are very nice, but very pricey. Our TT cost (in parts) less than $200. However, you do need a $325 3D printer and a lot of time on YouTube learning how to use the design and slicing programs and then how to program an Arduino (the controller). In the end, we have a TT that is loaded with animation (as you will see later) and provides the same level of functionality as those on the market.
As to my previous post, here are some pics's of the actual TT top, disc, slipring, bottom mount, stepper motor, and control box. The mount for the stepper motor was the 1st 3D part, and the control box was the 2nd. I have also included a vid of my friends design for the draw bridge that will provide connection from an outside line to an inside line so as not to block a bedroom door. All (except the stepper motor) done with a 3D printer (just a little teaser. The close ups of the stepper on the underside show the gears that were added to provide even finer rotational resolution. The square blocks on the bottom of the table were spacers to provide the well that the TT mounts in (done for realism). And I threw in a couple pic's of my very incomplete layout--too much time on TT and learning new stuff.
