I’m a big fan of time-lapses, but they are almost always more interesting when some sort of motion is involved. Normally the camera is rotated to make the subject (the world?) appear to move, but in this case,* the subject is a tiny grapefruit plant, photographed over several days of growth. It’s not a lot as of now, but you can see the resulting video after the “read more” link thing.
A scroll saw was used to cut most of this beautifully finished time-lapse rig, and a Shapeoko CNC router was used to cut the circular piece. I suppose one could also use a large hole saw if you didn’t happen to have a CNC router around.
A stepper motor drives the belt below the camera at a rate of one step per picture, which, in conjunction with the gear reduction going on, allows for a very slow rotation speed. Cleverly, the plant’s wooden pedestal is balanced on a cooling fan, acting as a thrust bearing for this relatively light load. Continue reading
