Here is a little demo of an instrument which I have just finished. I have spent quite some time getting this thing to work. I will continue working on this and making it better.

The magnetic cello has a similar size, shape, and playing style of an acoustic cello. However, instead of a horsehair bow, the player uses a magnetic rod (the "bow") to induce a voltage in a coil (the "bridge"). This voltage is used to control the volume of the signal. The pitch of the instrument is controlled by resistive ribbons (the "strings") which control a second voltage. Note that this creation does not use a microcontroller or digital circuity--just capacitors, resistors, and the occasional IC, like in a simple radio.

This was finished over the summer. Now that I am in college (studying electrical engineering) I will be able to improve the tone, playability, ect. of this instrument. Sub to get the updates! Thanks for reading all of this.

The pitches sounded like a Viola, which sounds pretty cool.

Check out our newest video, it shows how strings are now selected by switches on the bow. You can't play power chords on this instrument (without an external filter) but you can do many things that you can't with an acoustic cello.

how do you do chords? how does it know which "stirngs" you want to bow?

How much do you want for the cello?

Hello, First I would like to congratulate him for trial, found it very creative. I would like to know where I can find any material related to the experiment, such as circuit diagram, components used. Well, I would like to be studying and getting m little more information on the subject. If you can send me some information thank you. Thank you for your attention.

@c4r50n1 I don't think I can post url's in the comments. I'll PM you the link.

@magnetovore Oh, that's cool. Can you link me to it.

@c4r50n1 The instrument is loosely based on the Theremin Cello, in fact.
