Automatic Object Movie Rotary Table
This is my latest hobby project -- photographic automatic object movie rotary table. It is used to shoot a sequence of photographs, then these photographs are assembled into an animated movie using QTVR (QuickTime Virtual Reality), Java, or MacroMedia Flash. This type of animation is becoming popular on some websites, and is the best way to showcase a product on Web.
Shooting an object movie using still camera (vs video camera) involves putting an object on a rotary table, then after each shot, the object is rotated by certain equally divided degrees, and continue on until a complete rotation. Having tried it myself, this process is very tedious. Then, it came to me that what if I synchronize rotation of object with my flash? When one photograph is taken, using flash of course, that will trigger a circuit to rotate the object.
Hence this project was born, though went through some costly mistakes and numerous experiments, I finally got a system that can take up to 20 pounds of load and rotate either 25 or 50 steps after each photo.
Now, I am very happy with it.
