INTRODUCTION: Our project is a wireless communication link which interfaces to the serial ports on the TI-83 and TI-84 calculators. SUMMARY: Our group created a wireless communication system for the widely popular TI 83/84 calculators. The system interfaces to each calculator through their 2.5mm serial ports. Using an instant messaging chat program written in TI […]

SensCap is a device that guides the visually impaired around obstacles. Introduction We designed and built a device to be worn on the head and around the hip to aid the visually impaired maneuver around obstacles. It provides information about obstacles near and around the head. When used with a cane, the user will have

Our Keyboard Synthesizer project aims to create a multi-instrument keyboard that can record several different synthesized instruments and play back the track simultaneously. We took a children’s toy keyboard and adapted the printed circuit board within to play a range of notes from various musical instruments. Our user interface is a phone-style keypad for command

Introduction For our ECE 4760 final project, we designed and built an electric guitar pedalboard that will take in an analog audio signal from a guitar and add analog effects such as equalization, gain control, as well as digital effects such as distortion, compression, and chorus. The processed sound will be outputted through a ¼”

Introduction and Rationale Our ECE 4760 design project integrates three different kinds of sensor measurements to track a user�s movement speed, regularity of gait, force on impact, pronation of foot, as well as other information that may be useful to a podiatrist. We believe there is a need for a cheap metering tool that can

For our final project we decided to construct a human tracking rotating platform that supports a fan. The platform, using dual element Pyroelectric Infrared Sensors (PIR) sensors, rotates itself independently to direct air flow to whatever position a person moves to. In addition, the fan includes another setting that allows precise rotation between two people.

Introduction The goal of this project is designing microcontroller operated drum set and guitar which are only consist of drums sticks, pedals, and pick. This is done by implementing accelerometers which are connected to the microcontroller. By swinging the sticks and picking the guitar in the air you can play drums and guitar. We also

Introduction We created a system that takes input from a piano and displays the musical notation for it on a television screen. The system uses hardware amplification and filtering of a microphone output with code in C compiled on two Atmel Mega644 microcontrollers. The basic tasks required are pitch identification, measurement of note duration, and

Part I. High Level Design 1 Rationale and Problem Overview As regular grapefruit consumers, both of us could appreciate the value in automating the cutting procedure. We saw the problem as suitable for a final project because it is [very] challenging while requiring a combination of software, analog electrical hardware, and physical components. The device has
