The best way to really get an idea of an item is to touch it, hold it, use it, take it apart, and see its guts. I try to do a good job of showing the guts of what I build but it's the internet so the tactile sensations will have to wait until better peripherals exist. In the mean time I like to show rotational views because they give a spatial sense to what's being seen. Personally, I think they look cool.
My original intention was to use a continuous rotation servo motor to slowly spin a rotating platform, a lazy Susan, and activate a camera shutter whenever the servo motor turned a full rotation as the servo stopped then make a full stop once the lazy Susan made one complete rotation. It was going to be controlled by Arduino.
As I built this project the automation seemed overkill. Usually I'm all about overkill but I stopped myself this time with the hope that more people will actually build one of these. That is not to say that I won't build a deluxe version in the future.
Enough background.
----------
A dull2 1/2" (63mm) hole cutting saw was inserted into a drill press and a piece of scrap 1/2" (12mm) plywood was cut half way, flipped and the cut was completed from the other wised to avoid hole blowout. The dull bit left scorch marks on the wood due to excessive friction. The wooden biscuit was sanded on a belt sander by first holding the center hole and allowing the the biscuit to spin. A more effective method was to place a screwdriver the hole and allowing it to spin on the sander while holding it an an angle to the belt travel direction.

The sanded disc was divided into eighths by sight using a steel rule. Spots were marked 1/4" (6mm) from the edge on each segment line and small holes were drilled. Countersunk neodymium magnets were installed at each hole with screws which came with the magnets. There is a magnet approximately every inch (25mm) on the circumference of the wheel. The number of pictures taken in a given session will be determined by the circumference of the rotating platform.
