Fully portable polyphonic harp using conductive fibers and neodymium rings as main interface between musician's fingers and the instrument. Metalic tray from mother-in-law's kitchen used as a resonator to provide the instrument with a particular resonance frequency & timbre.

How does it work?
9 ring-shaped neodymium magnets are attached by means of conductive fibers to an MPR121 capacitive sensor which is attached to a daisy running full-tone and half-tone synths. Each magnet is corresponding to one note of an octave, additional one is used to switch between the octave. Simultaneous touch of two juxtaposed tones generates their intermediate half-tone.
Mono audio-signal is amplified and transferred to a shaker attached to a sweet spot on a metalic kitchen tray. All is powered by a powerbank, whole instrument is thus fully portable .
A powerful microcontroller for synthesis programmed through C++, Arduino, Pure data and Max MSP
A touch capacitance sensor can detect anything that is conductive
