GuitArduino is a futuristic guitar without strings

Alvin Coessens, Steven Thys and Lucas Daniels have built an experimental musical instrument in the context of a project for Fablab and the Media, Arts & Design Faculty in Genk, Belgium. The case description was to explore the possibilities of making a musical instrument through the newly openend Fablab (a concept from MIT). They build a futuristic electric guitar that could play music just by a touch , no plucking or picking is required. Also, the guitar has no strings attached, only the visible fret-board is there.

The team replaced the snares with light sensors (LDR’s) on the upper part so one can hold his fingers over the sensors to generate a tone, and integrated custom build capacitive touch sensors in the central part of the guitar to expand the range of notes.

The guitar was made out of 3.5mm multiplex wood. The beating heart of the GuitArduino is an Arduino Uno Board  which connects all the sensors to a computer. On the computer PureData is used to send the sensor information as a MIDI signal to Fruity Loops (or any other audio composing program of your choice). In Fruity Loops, the signals from the different sensors are attached to different sounds of a MIDI guitar. Coupling GuitArduino to software like Fruity Loops allows one to play any sort of sample or range of samples with the same instrument, kind of like a synthesizer.
