Nice job! I'm very interested abut your solution for motoring the DEC axis. What kind of parts did you use? Where did you buy them?

The infamous Chinese platform... taobao

Ha! I was not familiar with Taobao but now, I'm.

If I wanted to do the same in my mount, do you have a list of parts that I could buy somewhere? I think it is a very tempting project to try to motorize the DEC plate.

I checked my taobao record, I believe this is the motor:

And this is the main gear:

The motor controller is rather easy, since this is a DC motor only... you reverse the polarity, the direction of rotation will change.
