My team and I all collaborated on all parts of the construction process. We
ultimately made MESI using cardboard, foam mesh, and fabric (in addition to
the electronic components).
When finished, M.E.S.I. was comprised of a large, soft board,
9 embedded photosensors, and 3 speakers. The photosensors detect when
hands or objects move over the board. As different combinations of
sensors are covered, the board produces notes through the speakers. Up to
3 notes could be played at once, making it possible to create harmonies and encouraging
kids to share the experience of playing music with their friends.
Another key component of this design is that it is durable and easy to clean.
The soft outer layer of the board can be easily removed and washed.
In future iterations, smaller microcontrollers could be embedded in the board,
eliminating all of the external wires and electronics.
