3d scanner

[iplayfast]

You do need to rotate the object your scanning.
The 100 dollar printer/scanner dose not ship with a motorized turn table but instead will ship with a simple way for you to move the turn table very smothly by some other means.
We have come up with many many ways to do this but before I post about them Id be curious to know what the inventive minds here at 3d print board can come up with.

If you had an old style record player, and had a way of tracking how many times a second it rotated, you could then take a picture at the precise interval that the turntable would be rotated at any degree.
Also if you took a series of pictures of something rotating on a turntable, and found the "degree of closeness" to one image you would get a sign wave where the peaks would be where pictures were exactly alike. That would determine the period of the turntable.
