Thought-controlled music - playing synth with arm prosthesis

Psychologist and DJ Bertolt Meyer designed an electronic circuit that attaches to his arm, which then controls a synth with his thoughts. The SynLimb attaches to Meyer's arm prosthesis instead of his prosthetic hand. It converts the electrode signals that his prosthesis picks up from his residual limb into control voltages for controlling his modular synthesizer. The SynLimb allows him to plug his prosthesis directly into his synthesizer so that he can control its parameters with the signals from his body that normally control the hand. "For me, this feels like controlling the synth with my thoughts," Meyer says. Show the demonstration below.
