Hi everyone,

Since my 74861 was out of work, I kept on trying to make a simple turntable, which could work with Marklin CS3, it should be easy, reliable and cheap.



There are 3 main issues:
1. Shift direction of motor for turntable: I use a servo to change the positive and negative poles of the motor;




2. Pick up power and signal of contact track: I use Pogo pin same as Marklin, Marklin has 8 units, I can only make 5 units, but I add one line on the circle track on turntable base, then total 6 lines: track O, track B, contact track, shed light and two for blink lights;




3. Stop deck of turntable at specified location: I use magnet and Hall sensor to achieve this.




You may get more information from video and photos.

Have fun.
