wireless battery-powered instrument

October 14, 2013

This project allowed me to improve my abilities to code onto a micro controller and code in C. The goal of this project was to design and construct a battery-powered instrument capable of playing a tone for a specified duration when requested via an mRF wireless command from a host computer.

A few design considerations in this model included having an open accessible back while still maintaining rigidity in order to access circuitry. The entire structure was laser cut and assembled via pressfits and screws. The front face attaches to the speaker with screws and pressfits into the arms at the bottom and leans against them at the top, contributing to the structure's balance. Furthermore, the knobs on the front panel allow for the user to turn the device on or off and adjust the volume as well.
