As long as you have a camera with long shutter capability you are definitely on your way, but to create 'smooth' rotations it's necessary to have some sort of "Camera Rotation Tool" and a tripod ... I think probably one of the easiest ways would be to get a 'generic' arca swiss l-bracket and tripod with a head that can rotate 360 ... it's kind of hard to explain but if you look up camera rotation tool I'm sure you'll get the idea, there is even a tutorial video, as well a facebook group if you are really interested.
