TechBuilder BB8

YouTuber, TechBuilder shows how to build a real working Starwars BB8 droid by only using household materials and Arduino! (No 3D Printers! No CNCs! No Mills!) Amazing work! I would (of course) use Parallax brains (microprocessors).

The droid can be controlled by any smartphone. It also talks as well. The makeshift design had cut the overall expenses to $120, making it cheaper than the Sphero toy.
