Master Todd Kumpf used to create this functional work of art old turntable Yamaha YP-D4, computer Raspberry Pi, seven-band graphic equalizer, and a five-inch screen of the portable TV that had been placed in a home-made body of oak. All graphics on the front panel is made by galvanoplastiki. The device has a pair of AUX connector, and can play both records and audio from an external device as Wi-Fi.
