C2 - utopia

Musical/visual/dance performance of Borut Kržišnik's new album, Utopia, with Ryuzo Fukohara dancing and triggering / modulating sounds and projections by Simon Svetlik.

We plan to plant 5-6 sensors on Ryuzota, the IMU signals will be converted into midi for Borut in Simon.

Sometimes doesn't want to flash; hold BOOT button and click RESET to enter flash mode. cnmat/OSC SlipEncodedSerial needed a modification; constructor argument typecast to HWCDC.

Should be compiled with -DARDUINO_USB_CDC_ON_BOOT=1 to enable USB CDC.

We also need some velcro tape to make sensors easily mountable and protoboards to hold it all together.

And a charging station for batteries (TODO).
