This is a gesture controlled MIDI controller I designed and built as a commissioned work. It has a tilt sensor which affects to MIDI parameters it is sending out but also the color of the ball. I built several stereotypes to get it work the way I preffered. The pictures are from third generation. I am currently putting together fourth generation with better LEDs.
Pallo has two groups of four LEDs: red, green, blue and white LEDs. All are LEDs are superbright. I’m using red, green and blue leds to for rgb colors and white to give white color, as it seemed that creating white with colored leds was difficult. In future models I’m testing true superbright RGB LEDs that shouldn’t have this problem.
The heart of the controller is Arduino microcontroller. I have used Pro Mini -version of Arduino. It is fully functional Arduino without usb connection and built to a circuit board size of a stamp. The tilt sensor is Lilypad Accelerometer and the device is powered from on 9V battery. One battery should last approzimately 10 hours.
The MIDI signal the device is sending out is two different CC parameters that are tilting in X- and Y-axis. Sadly there is no footage of using the MIDI out of the device which I didn’t have time to shoot before I sent the ball(s) to my client.
If you are interested of custom MIDI controllers, please contact me and I’ll see what I can do.
Making of with more details coming soon…
