This beautiful build is a motion dolly for making time-lapse videos. It is at a point where you could consider it complete. After all, the segments featured in the video after the break look marvelous. But [Scottpotamas] has a few additions planned and it sounds like it won’t belong before he accomplishes his goals.
The build is a linear rail on which the camera rides. In the image above you can see the stepper motor which moves the camera mounted at the far end of the rig. This is controlled by an Arduino. Currently the camera is responsible for timing the capture of the images, but [Scottpotamas] says the firmware is nearly ready to hand this responsiblity over to the Arduino. The system is modular, with a simple setting for the length of the track. This way he can swap out for a longer or shorter rail which only takes about five minutes. He also included support for a panning mount for the camera. It allows the control box can be programmed to keep the subject centered in the frame as the camera slides along the track.

It’s neat to watch these lilies open and close during the time-lapse movie. But what makes it even better is to see the camera slowly move during the time-lapse event. It’s thanks to a special dolly which the photographers built for this purpose.
The system is based on two curved and inclined pipes which make up the rails of the system. The dolly that rides along the rails has a geared motor on it which turns at 2 RPM. This is used as a winch, spooling a string that is tied to the high-end of the rail system. As the winch winds the string, the dolly slowly moves along the track.
To make this work over multiple days they covered all of the windows in foil and lighted the room with fluorescent fixtures. An intervalometer was used to trigger the camera every three minutes. An Arduino monitors the camera’s shutter LED via a light dependent resistor. Sixty seconds after an image is take the Arduino will drive the dolly motor for a few seconds
The finished video, as well as a hardware show-and-tell, can be seen after the break.

A little bit of technology goes a long way when it comes to stop motion animation. In this case it’s a trio of simple camera dollies built during production of a short film called The Maker.
A Dolly is a method of mounting the camera so that it can be moved smoothly during a shot. Of course with stop motion the movement actually happens between the shots so it’s even more important that the camera be moved accurately. The video after the break shows off how they added CNC control for the camera. The first dolly was built from a pair of PVC pipes with a sled that moves along them. A motor moves a loop of 35mm film which is attached to the dolly. This is a great choice of materials since it doesn’t stretch and it’s free (one of the filmmakers is a projectionist). The next dolly is made from a flatbed scanner, and the final offering is seen above. Built from a bicycle wheel it provides a stationary platform above the hub for the models, while the camera rotates on an arm attached to the wheel. You can watch the complete film here.

Documenting your build process can sometimes be an incredible pain, as it’s quite difficult to take pictures or video while you are in the middle of soldering. Professionals who demonstrate things on TV for a living have the benefit of a camera crew and special rigs to catch the action from every angle – the rest of us don’t have that luxury.
[Steve] felt the same frustrations as many of us do, and decided to do something about it. He built a movable camera dolly that can be suspended from the ceiling above his work surface for less than $30. The bulk of his camera dolly is built from PVC piping, with assorted bolts and washers holding things together. Skateboard bearings were used as rollers to provide smooth 2-axis motion for the entire rig, then he hung the entire apparatus from the ceiling joists over his workspace.
According to [Steve], the build process seems relatively easy and should take no more than an hour or so, and it can support pretty much any full-size DSLR camera you can find.
Stick around for a quick video tour of his camera dolly build.

[Brian Grabski] was asked by a friend to design and build a dolly that would move a camera during a time-lapse sequence. Above you can see the product of his toils, and the videos after the break show off the parts that went into the design and showcase effectiveness of the build.
The dolly is designed to ride on a pair of tubular rails. These can be bent to match any desired path and the dolly will have no problem following it thanks to two features. First, the triad of skateboard wheels on each of the three corners are mounted on a swivel bearing that allows them to rotate without binding. The other piece of the puzzle is a set of drawer slides that let the third support move perpendicular to the other two sets of rollers. A motor drives a geared wheel to move the dolly along the track with speed adjustments courtesy of the motor controller. There’s also a failsafe that will shut the system down when it runs out of track, protecting that fancy piece of hardware taking the pictures.
We’ve seen timelapse equipment that moves the camera in the past, but those hacks usually involve rotating the camera along and axis. This track-based setup is a well executed tool useful at all levels of photography. We can’t wait to see the arch-based dolly that is teased at the end of the demo video.

[Andrew Curtis] does fantastic timelapse photography. He found that he wanted to be able to move the camera while taking the shots to give motion to the final product. While this isn’t exactly a new idea, not too many people mess with it. The dolly to do it with can be quite expensive as it has to support the camera and move it in an automated and controlled fashion. [Andrew] has been working on building his own dolly and has documented the process.
