NIME: Interrupting Music Box

 

This music box interrupts itself a lot.

Essentially, my idea for the project came as a series of interruptions, which in turn led me to want to create an interruptive music box. That is an intentional quality of this device. Essentially, it is mapped to accept input from both the right and left button on the circuit playground express, as well as accept input from the potentiometer. When a button is pressed, it overrides any other input. 

This project works through the use of two buttons, and by turning the potentiometer. Every single interaction with this project interrupts another aspect. When music is played, the servo will stop moving. Alternatively, pressing down on the right button will allow for a moment of escape from the music box’s clicking. The servo will remain paused for as long as the user holds down the right button. In regard to the potentiometer, when turned, the servo will interrupt its own spin cycle and go in an alternate direction. There is some indication drawn onto the box to let the user know what might happen based on interaction; however, the feedback is only apparent through an aggressive change in what is happening. 

This device is not so much a music box, as an annoying single person game. In some ways, I can see a similarity to an omnophone. 

I suppose the biggest question I have is how could I have improved the aesthetics to better depict my intention?
