Overview

Traditional control devices such as a computer mouse and touch screen are used to sense movement on a flat surface. The Radio Drum takes this concept one step further by tracking movement in a three dimensional space. By moving a small transmitter over a receiver board, the Radio Drum can be used to detect position along the x, y, and z axis by utilizing capacitive moments. The applications of the Radio Drum are limited only by the imagination. Some current projects make use of the Radio Drum as a musical instrument as well as a communications device for quadriplegics. Currently the entire system must be purchased from an outside supplier, and is expensive and bulky. The control circuitry will be redesigned with the goal of minimizing cost and size in mind. The goal of this project is to redesign the Radio Drum control box for UVATT with the purpose of minimizing cost and size. UVATT is currently exploring applications of the Radio Drum as a 3D position and motion-sensing device in areas such as music therapy and communication facilitation for persons with limited motor control. The current system is very expensive, and has a number of features that are unnecessary to UVATT. The existing design will be simplified and customized to the specific needs of UVATT. A number of potential improvements are being investigated. The MIDI control circuitry will be eliminated, as well as the LCD screen. More robust connectors and cables will also be incorporated where possible. If time permits, a PCB layout will be generated, however the first priority is to develop a functioning circuit. Finally, this report outlines recommendations for individuals who choose to continue with this project.

The Radio Drum is a three dimensional motion sensing device. It uses capacitive moments sensing to determine the position of an object moving in a three-dimensional space above a surface. The goal of this project is to redesign the Radio Drum control box for UVATT with the purpose of minimizing cost and size.
