Mind Controlled Robot using Arduino and MindFlex
NeuroSky produces and supplies an IC that can provide filtered, raw EEG data from electrodes connected to our head. But they also produce an awesome hardware equipment for toys such as MindFlex (a game in which a ball is mind controlled using focus and relaxation level of our mind). For us this was a cheaper option to get the EEG data for our project . It could give us everything, neat and filtered for less than half the cost.
