Say hello to the Magnetic Cello, the perfect companion to your magnetic drum kit. Crafted by college student David Levi (AKA "Magnetovore"), the instrument vaguely represents a traditional cello in structure, but the similarities pretty much end right there. To play it, for example, musicians use not a horsehair bow, but a magnetic rod that produces a voltage within an attached coil (the "bridge," in this case). Its "strings," meanwhile, consist of resistive ribbons connected to a voltage-controlled oscillator, allowing users to manipulate volume with the magnet-bow. The result sounds surprisingly cello-like, though Levi says he's still tinkering with its tone and playability. Waltz past the break to see the beast in action for yourself, or find more details in Levi's provisional patent application at the link below.
