This is the preliminary design for the structural frame that will house the recorder and all of its electronic and mechanical components. This design is a four sided open box design, which simultaneously allows for all the structural components to be attached and so that a viewer could observe the inner workings of the instrument. In the design, in order to maintain access to all holes on the front and back of the instrument, the recorder will be turned sideways, so all push solenoids, the arduino and the relay board can be mounted on either side of the recorder on shelf-like platforms.
