Justin Lange, a student at NYU seems to have been deeply missing his dad's guitar play, whose shoulder got dislocated in an accident and left him unfit to play the guitar. Justin though tried to win back dad's happiness by working on a project that would help his father play guitar again. Though, his dad remained pessimistic about the possibility of such thing, Justin successfully completed a mod for guitars, dubbed as Folkbox.
Based on open-source single board microcontroller, Arduino the Folkbox mounts a frame over the finger board accompanied with a row of buttons mounted below the neck. The frame over the finger board is in turn connected to eighteen solenoids employed to push down the strings between the frets. The two-row button board helps in making choice of the desired chord. While the first button lets you choose the key, the second allows to switch between the chords. We were impressed by the scope of this setting as it can be used by people with different types of disabilities. In case the arm is completely unusable the row of buttons can be replaced by a foot pedal array to help play the chords. Though the current setting is limited in number of chords it can play, Justin is committed to add more chords to it with time.
