Hello, I found this really interesting Ball and Beam experiment on the web:

I would like to find a rotary servo like the one in the video.

Can anyone recommend suggest a rotary servo that is similar to the one in the video?

Thanks,
Joe

Anyplace that has parts for radio controlled models.

The mechanics look reletively simple. The PID calculation software, and software to drive the servo that is hard.

Good luck,
