fun at Columbia's Computer Music Center (CMC)!
acoustically self-resonant aluminum and 26 gauge galvanized steel sheet metals
High-powered magnets + piezo + impedance matching circuit + self-wound coil + 250 W power amp + galvanized steel & aluminum sheet metal. it's a prototype for a self-resonating, feedback system for multiple strips of sheet metal hopefully to be incorporated into an upcoming installation. all analog baby ; )
