This is much better in the real world with big lenses making a GigaPan, it's sturdy.
I wrote a simple library for it. You just need a screwdriver to modify it.
I removed the internal stops and made a simple one on the outside.
You could design a bearing to use with our tiny motors.
But I just mounted my T2i on the shaft! Made a wooden base for the motor.
It works fine so long as you have a level table or rock to set it on.
The Bescor goes 7deg/sec max.
Our stepper 30RPM which works out to 180deg/sec or 25x as fast.
Too fast to stop blur with a 200mm lens spinning on it.
That's why I wrote unramp() to stop and start.
With the Bescor I can take a panorama or Gigapan without stopping @300mm.
With the stepper I can capture 360 deg in 2 seconds.
I've been making endless panoramas, they just keep going and going, round and round...
