“If you want to add interest to any video you are making, a good way to doing it is to add motion. There are an infinite number of motion effects you could use in your videos, but a classic, and very pleasing one, is a sliding effect. You will see this effect used in numerous videos in which the camera smoothly slides across the frame.
Producing shots like these requires a bit of hardware. A camera slider consists of a rail across which a camera smoothly slides. For more controlled motion, many camera sliders use a motor. However, for such a seemingly simple device, camera sliders can cost a bit chunk of money.
Thats why, in this Instructable, we will be building our own motorized camera slider. The slider will use 3D printed parts and off-the-shelf components. The slider will be controlled via WiFi using a bespoke application. The cost for this whole project will be a fraction of what it would cost to buy a motorized camera slider at retail.”
