Our wireless music player allows the user to listen to uncompressed digital audio streamed over a wireless link. The music player reads uncompressed audio data from an SD card in an immobile “base station.” A pair of Xbee transceiver modules are used to stream data and control signals between the base station and a portable …
Introduction This project is a proof-of-concept device that transmits an audio signal using a laser beam, while removing the need for the user to align the beam themselves. For our project, we created a mono-axial transmitter/receiver setup that converts an analog audio signal, via a standard 3.5mm jack, and transmits it via a laser to …
Introduction We set out to make an easy to interact with, highly custimizable POV display In deciding on a project we looked for a challenge that would have a good mix of hardware and software problems. We ended up primarily concentrating on looking at unusual display technologies and decided that a persistence of vision(POV) display …

Introduction The goal of our project was to design a low cost and user-friendly FM radio receiver. Our project uses a FM receiver integrated circuit to perform the pre-processing units that are needed before the desired audio signals can be heard. The radio frequency is too fast for processing with our available hardware and the …
Introduction “We developed a wireless receiver capable of receiving and playing audio transmitted over an 802.11 Wi-Fi network” project soundbyte For our ECE 4760 final project we developed a wireless receiver capable of receiving and playing audio transmitted over an 802.11 Wi-Fi network. Our system was constructed using an Atmel ATxmega256A3U microcontroller and a RN-XV Wifly module made …

Our project is inspired by the commercial product, PicoDopp, which uses a similar scheme for foxhunting. Foxhunting is a contest where participants try to locate a transmitter, called the fox, simply by monitoring the signals it transmits. Typically this is done using highly directional antennas — antennas that only receive signals from one direction. However, …
We implemented an optical microphone which converts distant vibrations, including sound, to an audio signal. Measuring the reflection of a laser beam from windows or glass, it possible to hear sounds near the target. The system also includes frequency spectrum analysis with a real-time display and user-configurable ranges, and it also has an output for …

Introduction There’s a simple question asked by runners, walkers, joggers, and anyone who moves. How fast am I going? Runners want to pace themselves, athletes are trying to train for events, and even on a day to day basis you might wonder how far you are travelling. There are various existing methods of measuring pace, …
