Galileino 2

Galileino is a system to provide a hardware simulation of the Earth rotating on its axis and revolving around the Sun, meant for educational purposes.
It basically consists of a portable rotating arm, having at one end an Earth globe rotating on its axis, inclined as the actual Earth rotation axis, and fixed at the other end to a heavy hub that remains stable on a surface, while the former end can perform a revolution around the hub, so as to simulate both Earth rotation and revolution. A ball lamp is hung over the hub, to represent the Sun.
The earth rotation is actuated by a stepper motor and the revolution is actuated - in the version 2 - by two similar stepper motors in parallel commanding a rubber wheel moving on the underlying surface, all controlled by an Arduino.
The system is easily portable, as it consists of a first part being a rotating arm with globe, DC motor and gears and two pulleys connected by a toothed belt, a second part being a heavy hub that can be quickly connected to the first part with wing nuts, a flat connection cable and a control circuit box.
The system can be operated on any flat surface larger at least so as to contain a 120 cm diameter circle.
