Made the dispenser of an automated reward system controlled by an Emotiv EEG at my first hardware hackathon! (Silicon Chef 2014) This contraption is meant to dispense candy when concentration goals are met. It's composed of just some toy parts, cups I found in the kitchen, and tape! Clear cups were used so the audience could see what's inside, and the paper cup for stability. The other reward system utilizes the Twilio API to send rewarding text messages. Materials: servo, parts from a K'nex kit, tape, recyclable cups, Twilio API, and a SparkFun RedBoard.
