I usually move the dolly by hand but for time lapse or slow movement I use a parallax continuous rotation servo that winds fishing line through a pulley attached to the dolly and onto a small spindle. I control the servo via a Traxxas (for a remote control car) controller and receiver. The Traxxas controller has a potentiometer on it that allows speed control of the servo in both directions. An easier option would be a rotisserie motor - I found one at Goodwill but didn't wind up using it cause I wanted to go wireless.
Give credit where credit is due, this project is a remix of these two projects:
DIY video & timelaps electrical dolly

Unfortunately, I am not mechanically oriented.
Do you think it will hold a camera like the Panasonic DV100A?
Thanks.

Is there any way that you could do a quick video w/ some detailed shots of the
"parallax continuous rotation servo that winds fishing line through a pulley attached to the dolly and onto a small spindle." and "the servo via a Traxxas (for a remote control car) controller and receiver." also how you attached the camera mount to the motorized arm.
Thx B
