Mind Balls :)

We were at the biggest music festivals in Poland (OWF, Opener, OFF)  in 2015 with our Mind Balls zone. Everyone with 3 bills of payment with MasterCard was able to win a prize. But there was a challenge – balls that one can move with their power of brain :).

One big construction, one Arduino Uno, one big stepper motor, one engine driver, one brainwave headset, few applications and a lot of cables equals FUN 🙂
