ARDUINOME/Chronome - FLIPMU
An Arduinome is a MIDI controller device that mimics the Monome using the Arduino physical computing platform. The plans for the Arduinome are released under an open source, non-commercial use only license. The Arduinome platform is noted for providing a lower cost alternative to the Monome and allows greater hackability of the interface.
Additionally, the Chronome was developed as part of my thesis, and aimed to incorporate new work from the community into a single device. This included support for RGB LEDs and pressure sensitivity for each of the 64 buttons. The Chronome was also released as an open source, non-commercial license.
