Martin and Kilian love playing the Ocarina and the Piezo speakers inspired us :) Hence we built a little Arduino Ocarina that allows you to play one Octave (8 tones).

It is activated by pressing the chin on the Ocarina. The volume can be adjusted using the attached Potentiometer.
We couldn't get the battery pack running. Therefore the USB Cable is still attached to the Arduino to power it.

I have quite a lot of experiences that I forget to bring my Cal ID card when I go to the gym or South Hall. Especially, it really annoyed me this weekend because I came to the South Hall twice without my Cal ID card so that I wasn't able to enter the building.
