- jasonostrander 11y agoThoughts on how they built this?
- jasonostrander 11y agoMy guess: a flywheel inside the ball to keep it stabilized, along with a motor and series of magnets to move the "head" around.
- ralfd 11y agoSure, but how exactly? If I hadn't seen the video I would have guessed a practical prop impossible. Mashable has an article about it, but they too have some hand-wavy-magnet explanation. http://mashable.com/2015/04/16/star-wars-bb8-technology/ http://mashable.com/2015/04/16/star-wars-bb8-technology/ Too bad there is no discussion on hn or reddit about the workings.
