O'Cello MIDI v3 [concept]

An attempt to make a quadrophonic pickup system for the O'Cello. This, coupled with copper tape on the 'frets' of the o'cello that make contact with the strings as they're pressed down and send an electric single down a resistor ladder, would've allowed me to detect when an individual string is being played.

However, due to the resonance of the cello, the strings can pick up vibrations from all the other strings. So a big pluck/note on one string may register as a small note on all the others. This renders the whole

Plus the whole thing just takes up a lot of space and wouldn't be comfortable to play with.

Anyway, I figured I put this out there just for the sake of reaching a 'checkpoint' on this struggling project...

To get the Right side pickup holder, mirror the object in your slicing software of choice.

Note that the Right side Arm is actually a different height.

The two weird-looking '[ ]'-shaped parts use an MGB single-string pickup: https://mgbguitars.com/collections/pickups/products/single-pickup-with-cover

The other two are just flat coils: https://www.amazon.com/Magnetic-Levitation-Electromagnetic-Induction-Experiment/dp/B0B9332ZZY/

(I tried to use small electromagnetic relay coils, but I couldn't find a way to safely extract the coil from the body of the relay.

You've gotta toss some magnets on top to make it work as a pickup though.

Screws are M3s and M4s of various sizes. Nuts required.
