Summary

I had a turntable which I wanted to use for 3D scanning, but turning it by hand made things more difficult than they already were.
Uses a NEMA17 motor, some M3 screws and a rubber band which fits over the stepper wheel.

Really nice. Is the power of the NEMA17 really enough to turn a person with 80-100kg? Which shield you are using for the NEMA17?

As you can see, this is a very small turntable. There is an EasyDriver driving the motor, and an ATTiny25 controlling it via a potentiometer. I can't imagine the torque being enough for a person. The plastic parts are certainly not strong enough for the task; maybe when the design is lasered or cut out of stronger material, it should suffice.

what kind of software to scan you use?

I have tried the Microsoft Kinect SDK, ReconstructMe and some other software. They become quite touchy when the object is rotating - not the camera. Whe I find the time and a good line laser and webcam, I will try David Lasescanner next.

Hello NilsRoe, quick question when you say Laserscanner you mean adding the laser to kinect (lined up some how) and it will give back better quality?

David Laserscanner works differently from Kinect. It uses a line laser and a webcam to scan in a 3D object. You place an object in a pre-calibrated area (with a special print-out pattern) and scan along the 3D object with the line laser. Then you turn the object slightly and scan again. Repeat until you have scanned all sides of your object.
