Drawdio an open sourced project established by Jay Silver. The design essentially turns the act of drawing into sound, through the conductivity of graphite and interconnecting touch, through the conductive human body. The sound produced fluctuates depending on the resistance between pencil point and finger point. Our objective is to develop the existing design by directing the project into a stage of refinement. Starting with reducing the scale of the electrical components, as well as in housing the design but still allowing creative freedom for further iterations. Our contribution to the Drawdio design introduces digital manufacturing, by implicating the use of milling PCB boards and 3D printing.
