On the quest for new tangible interfaces Martin Hertig experimented with Zippers. The result is Zippy, a guitar bag transformed to a simple, but functional guitar. By pulling the zippers you can play it. One Zip is for playing notes or chords, one for changing the bar and one for the vibrato.
The zippers of the bag were transformed to MIDI-Controllers using an Arduino and multiple types of conductive thread stitched along the zipper. The Arduino was turned into a Plug-and-Play Midi-controller using the Hiduino-Firmware. The guitar-sounds are produced inside the bag by a Raspberry Pi running FluidSynth.

Created by Martin Hertig at ECAL, Sensible Data is a playful installation consisting of three machines that collect user’s personal data, evaluates mood, age, gender and beauty, to create a ‘passport’ that user can take away but which also randomly sent (without user’s knowledge) to another participant.
