Still very much in progress, but here’s the first iteration of my motorized camera slider. The camera slider ends are this part, and the carriage is this part. I also learned about silicone spray to get things sliding more smoothly, and the fact that it’s better to leave bearings a little loose if you don’t have precision alignment.
The “motorized” part is pretty simple…actually too simple, and I need to complex it up a bit. It’s a continuous rotation servo with a spool attached and some string wound onto it. It just slowly pulls the camera across the rods. I need to add some controls to allow for setting the speed, and some gearing might also help things move a little better.
Ultimately, I want to have a camera rig that will move the camera slightly, then trigger the camera to snap a photo, then repeat. I’ve got the code for all this, so right now it’s mainly a matter of the mechanical build (needs improvement) and wiring things up without it being too messy.
