The instrument above is the final version of the instrument that we were required to make for the Forum. Originally I had only incorporated two of the three required aspects, these being tone generation and piezo driving, so in the trouble shooting class during the break the third was added (this being physical computing).
As can be seen above the Arduino board was used with the digital out sketch. This then could activate each of the six square wave generators that were made on the bread board using 2 4093 chips. Each oscillator also had a potentiometer and an LDR connected so as the pitch could be adjusted and the performance could be enhanced.
The signal ran out through a mono jack socket which was connected to a piezo driver which was glued to the bottom of a small cast iron fry pan. The second piezo (mic) was connected using a peg to a small metal bowl which could then be moved and adjusted to played around with the timbre.Below is a screenshot of the Cubase MIDI piano roll which in which the sequence of notes, (which was looped) was kept simple for the purposes of this exercise. There is also an mp3 in which both myself and Tristan Louth-Robins are playing the instrument.

Unfortunately due to my files being lost when 'My Data Bus' stoped its free access, I've lost the the mp3 which had highlights of this instrument being played (we videoed it). As I cannot edit this video at home I've uploaded the entire video clip to Youtube. (approx. 5 mins duration)
