Teenager Demonstrates How to Build a Life-Size BB-8 for Less Money Than the Toy


The Sphero BB-8 is cool and everything, but it’s just a tiny toy and also costs $150. After seeing BB-8 roll around on stage at the Star Wars Celebration last year, all we’ve really wanted is our own life-size version, and for the ambitious ones out there, this is how you can make that happen.

17-year-old Angelo Casimiro made this model for only $120 by using household materials, and you can to do the same by following his instructions on Instructables. It’s even controlled by smartphone just like the tiny Sphero version. If you didn’t get enough BB-8 action in the instructional video above, here’s a dry run with the head’s magnetic base to show just how well it really works:
