Hello everyone, this is my first project shared in Hackaday, before this project, I've been at Taipei Hackerspace for two years, where I started tinkering with Arduino, making interactive stuffs, and cubetrument here, is one of the projects I am currently tinkering with, I hope while sharing this project, I can also get your feedback, or even collaborate together, to make it even more playful.

The initial concept of cubetrument, is make a music contoller that is portable, and is visual attractive by itself, and bringing the music performance from stage to street, while playing it, it should also like dancing. One day I finish it, I want to bring it out to the street, dance and share the joy of making with passengers.

So that how it looks like, a cubic shape controller, with two axis on its diagonal, you can spin it. The pattern on the surface is the key for the controller at the same time, when it is touched, it will send signal to iphone via BLE and playing note by GarageBand.

And here is how it looks like:

It is a rotating cubic shape controller, and if you saw video above, you will see four rectangle geometry on four faces. When finger touched, it will sense capacitive changes and let micro controller send MIDI note to GarageBand. The rectangle shape is actually a wooden sheet sticker, and underneath the wooden sticker is an copper tape, which connects to capacitive sensing unit mpr121, and there are 12 input, and 4 input for each faces ( so totally 3 faces with responsible input key, one face is faked for aesthetic point of view).

As you can see, the wooden part is just sticker, and under the decoration is the half transparent, 5 mm acrylic, laser-cutted box.
