| The basic principle is to have different compartments in a rotating wheel come in contact with a piezo element. | | The mechanism itself is quite simple compared to the original design of a Drehorgel. I placed a plastic cylinder filled with different materials in the middle of a square made with metal frames. With a handle attached to one side and the piezo microphone going into the other, I can control the rate of how fast the "Drehorgel" will rotate. |

| The original idea was to create the Drehorgel out of cardboard. The major cogwheel would be rotated by a smaller cogwheel, which can be rotated using a handle outside the box. I planned to attach the breadboard and wires on the inner walls of the box so that they can be close enough to come in contact with the materials and stay out of sight when in operation. With cardboard, however, the audience couldn't see the interaction between the piezo and materials, and that was one of the goals for this assignment.
