Rokenbok is now Kid Spark Education. Go to now!

Justin, an incredibly talented and long-time Rokenboker, sent us this video showcasing his latest build - a "ball contraption."

His ball contraption took several months to design and build. It very cleverly uses a single X2 unit to power the entire machine and rotate the arms that carry the balls to the top.

Justin came to help build at the Maker Faire - Bay Area. After a great weekend of building, Mr. Rokenbok gave Justin a bunch of our upcoming gear teeth to help take his ball contraption to the next level. As you can see, the gear teeth are working perfectly!

If you want to see some more photos of Justin's build (and several other Rokenbokers), head over to our forums and take a look!
