David Levi aka Magnetovore, a student studying electrical engineering, has created a fantastic and very innovative magnetic cello, which resembles the size, shape, and playing style of an acoustic cello. However rather than using a bow, you use a magnetic rod which takes the place of the bow to induce a voltage in a coil which replaces the traditional bridge in a cello.
By moving the magnetic rod back and forth you can control the voltage that is used to control the volume of the signal. The pitch of the instrument is controlled by resistive ribbons that have replaced the traditional strings, and are controlled by a second voltage. Watch the video after the jump to see the innovative Magnetic Cello in action.
The Magnetic Cello design doesn’t use any micro controller or digital circuity, just capacitors, resistors, and the occasional IC. Levi is now working to improve the the tone and playability of his Magnetic Cello.
