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 […]

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 For our final project we built a prototype of a circuit intended for a picosatellite that measures temperature and acceleration, sending the information wirelessly back to a base station receiver. The N-Prize is an amateur rocketry competition challenging groups to launch a very small (10g-20g) satellite into orbit for less than $2000, and track

Introduction Our project can be described as a simplified implementation of Wii-Music, utilizing a Nintendo Wii Remote (Wiimote) to play a gesture-based music game with the player as a virtual music conductor. We decided to do this project since it exploited two of the Wiimotes more peculiar features: its wand-like shape and the embedded 3-D

Motivation Deciding a direction of the final project in ECE 4760 can be very difficult. With small Micro Controller Unit, we can build anything and everything. We felt compelled to find something very creative and ingenious and had looked around our surrounding and have found something interesting, printer. There is a conventional printer that moves

Introduction We designed a device that measures and graphs various aspects of AC power and acts as a computer-controlled remote switch. With the recent push for green energy and environmental friendliness, more and more people are concerned about their personal daily power usage. We developed a microcontroller-based device to measure AC power. The user will

The Trumpet MIDI Controller allows trumpet players the freedom of synthesizing from and composing on their native instrument. The Trumpet MIDI Controller combines custom hardware and software with the Yamaha Silent Brass pickup mute to convert any standard trumpet into a fully functional MIDI controller and MIDI pass through device for up to 16 channels.

Introduction One Sentence Sound Bite Air Drums is an electronic drum kit played in the air that eliminates the need for tactile drum pads. Summary We created an electronic percussion set with three upright percussion sounds and a floor bass drum sound. The upright instruments require one/two modified drumsticks to play, while the floor drum

Introduction Our project was to create two individual microcontrollers that can play banjo notes cooperatively to play two-part songs using nothing but sound to communicate and synchronize. Humans have had the ability to synchronize musical instruments together to achieve a single, coordinated multi-part song for thousands of years. In our project we attempted to simulate
