We present a kit comprising cardboard mechanical components and a custom printed circuit board, designed to support novices in building computational percussive instruments with everyday materials. We set three design criteria: accessibility, adaptability, and expressivity. We conducted two workshops with experts and novices to assess the usability of our kit and observe the variety of constructions that users make. The kit enabled both experts and novices to build working instruments and to explore creative experimentation with different materials and objects.
