[Jochem] wrote in to share a neat time lapse camera dolly he constructed out of Lego bricks. He is a big fan of the two-axis panning time lapse effect where the camera moves while recording images. He figured it would be easy enough to construct one of his own, so he dug out his pail of Lego and got to work.
The rig consists of a stationary motor platform which pulls a movable sled using a simple gear and string. The motor platform is controlled by an Arduino, which pulls the movable sled along every so often, snapping pictures along the way. [Jochem’s] Nikon D80 supports shutter release via IR, so he programmed the Arduino to send a quick IR pulse each time it has finished moving the dolly.
The rig looks like it works pretty well as you can see by the video below, but [Jochem] says that it still needs a bit of work. We just can’t wait to see what other time lapse movies he puts together once he finds an “interesting” time lapse subject.
