For a semester project in stage design my daughter constructed and built (with a little help ) a funny little barrel organ.
A T3.6 reads and parses midi files stored on an SD card and controls the 16 valves of the organ. The valves are actuated by micro servos which are driven by a PCA9685 16 PWM board. Teensy wise not a big deal but the effect is quite funny.
Here the 'making of' video if somebody is interested https://youtu.be/CT8jgxc9tUY
