It has taken a long time, but the Magnetic Cello is ready for demonstration.
This instrument 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.
I have just started college (I am studying electrical engineering) I will be able to improve the tone, playability, ect. of this instrument soon.
