The goal of our project was to create a persistence-of-vision (POV) analog clock using an LED display. The clock has a visual alarm system which lights up the entire display for two seconds if it reaches an alarm time. The current time and alarm times are preset into the clock before it begins to spin. […]

Introduction Our project records and extracts event-related features from a 36-point relative blood-oxygen concentration sensor array from the surface of the brain. We chose this project because of a combined interest in brain-computer interfaces. In an attempt to balance cost, complexity, and sensor density, we decided to implement a NIRS-inspired system. After collecting data from

Overview [top] As avid audiophiles, we wanted to apply our newly acquired knowledge of microcontrollers to build a fun consumer electronic device. Our project is a step sequencer drum machine. The user is able to program a 16-step percussion pattern using one of a wide range of percussion instruments on each of six different tracks.

Introduction In a Nutshell Our ECE 4760 final project was a car made of K’NEX that follows a LED strip. What We Did For this project we made a K’NEX car that follows a path made by a LED strip. We used two phototransistors to detect the lights from the LED, while considering ambient light.

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 We have designed and built a LED t-shirt capable of displaying the heart rate of the wearer via a pulsing LED heart. Largely, our project consists of two components: the plethysmograph and the LED display. How we came up with the Idea We had thought up the idea of a heart rate display led

INTRODUCTION Wouldnt it be cool to be this guy? Powerful laser shining into the audience, playing strings by sweeping your hands across the beams, rocking out in a room full of fog and fawning girls? We thought so. It turns out lasers are expensive, fog machines arent allowed in lab, and fawning girls experience some

Introduction The Weather Canvas is a robust outdoor weather monitoring system coupled with an indoor LED display. The outdoor system consists of a microcontroller, temperature sensor, humidity sensor, home-made anemometer, a Hot Wheels radar gun modified to measure precipitation, and a solar panel to measure sunlight and charge the microcontrollers power source. Once per minute,

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 For our final project, we built a mechanism that spun a linear array of seven LEDs at a velocity that made it appear as if a message was being displayed using persistence of vision for the human eye. To accomplish this, we first had to design and build the hardware components, which may have
