I started this project a few months ago to record video at a distance of 18 meters. Most pan and tilt systems I tried were not suited for slower and smoother speeds, but with the modified PT785-S System from ServoCity, I was able to get smoother control.
I used ServoCity’s worm drive to get slower motion and more toque.
Also, sometimes I needed to mount the camera up high. This is the light stand I used. The stand is reinforced with two galvanized steel pipes.
The controller took the longest to build. This is a early picture of the inside showing the motor driver and Arduino.
I have a Ethernet cable running to the motors and servo from the Arduino controller.
