[bouLed] Visualization and 3D printing

For bouLED, we will need to know its orientation. The orientation can be represented as a quaternion but we haven’t implemented Madgwick’s algorithm yet. So, I wrote a python script to simulate a rotation. The script generates and writes a quaternion on the script standard output.

In fact the sphere will be an icosahedron. It‘s the regular polyhedron made of 20 equilateral triangles. So I drew a equilateral triangle on openscad in order to print it in 3D. Then we will stick on this triangle a LED strip, and we will judge if the resolution is high enough.
