Building and Testing

I constructed a set of canvas bellows that seem to work well. Millboard was cut and glued to the inside of the bellows to provide a structure.





Here is a video of the bellows in action.



I still need to work out a way of sealing the ends of the bellows and attaching a tube to carry air to the accordion. I hope to build a few sets of bellows that will operate in concert to provide air to the accordion. Having several seperate bellows will provide a way of visualizing what the accordion is doing - giving it a strange set of lungs that show how the Deep Listening Device is reacting to what it hears.

I plan to use stepper motors to operate the bellows because they can be precisely controlled. I started working with the Arduino microcontroller, using it to drive a stepper motor. The stepper motor is connected through a Darlington transistor array to provide enough current to power the motor.



Here are some sketches of what may become the Deep Listening Device.
