The new Star Wars is coming to cinemas soon and a lot of people are already very thrilled for months. It is even possible to buy an BB-8 Droid made by Sphero which is advertised as the droid we are looking for as a merchandise.
In the video published by Sphero one can see that it is really a fun gadget which is controlled via smartphone or tablet and can, for example, go on patrol which means moving around autonomously in the room. Unfortunately as far as I found out, the possibility to program it is missing or at least very limited and it is as well a quite pricy toy.
So a different option is to build an own BB-8 Droid as altapowderdog did at the OHI/O Hackathon. In an YouTube Video he explains his construction in detail:
He states that he did not finish his project within the 24 hours duration of the Hackathon, but he will build a second version of the BB-9 droid which he hopes is more durable. I’m really curious about his next try to build the droid!
