After prototyping the capactive sensors and the polyphonic function I went about creating an enclosure for the full piece. I lazer cut and engraved a small box to fit in the palm of ones hand, and added a strap for security and comfort. It’s not the most ergonomic thing in the world, but it functions…
I ran into extensive problems with the capacitive sensors and wiring. Hopefully someon can exlpain this to me, but for some reason whenever I used wires longer than about ~6 inches they would begin to trigger from the proximity to the power wire. I then took apart the box and added another slot to run the sensor wires through, this proved also innefective as I ran into the same problem with longer wires. If I had more time I would have set up the whole thing inside the box, but at this point I had already taken it apart several times and was doubtful I could fit everything inside this small of a form factor. I settled for being able to hold the thing, and just not move around too much.
It has a volume control on the breadboard, and you can switch notes and key by changing the pins the wires go into.
I was unable to integrate the 3axis accelerometer for the other hand, but I’m happy with the piece as it is.
Happy to demonstrate in class!
