Introduction This goal of this project is to make an effective, low-cost 3D scanner. Summary Our project implements the hardware necessary for a laser triangulation 3D scanner as well as a PC user interface for controlling the scanner and acquiring data via an Ethernet connection. Our scanner facilitates 360-degree scans through the implementation of a […]

Introduction The purpose of this project was to design and implement a debugger for the ATmega644 that communicated through its JTAG interface and was capable of controlling program execution by setting breakpoints and accessing registers and memory. We have three main objectives in this report: To enable a user to properly download our code onto

Introduction For our final design project, we designed and built a prototype acoustic modem to serve as a physical transport layer for digital communications. It converts between a digital communications scheme (RS-232) and an acoustically coupled communications scheme of our own design. Our project consists of a pair of such modems to operate as transmit/receive

Introduction We created a handheld mouse device that measures its tilt and then wirelessly transmits the data to a base unit, which is connected to a PC through a USB cable and can be recognized by certain modern computers as an actual mouse. The purpose of this project was to explore the possibility of creating

Introduction For our Final Project in ECE 4760, we built a controller that interfaces with a computer running a PowerPoint display through USB. The device can control slide transitions based on hand motions or button presses as well as play MP3 files when it detects people near the display. We chose to do this project

Introduction The tags used to monitor wildlife can either be passive or active. Passive tags simply identify an individual, whereas active tags may send out a radio beacon or even collect data. These active tags, more commonly referred to as “bio-loggers”, are typically battery powered, and thus have limited life. This is especially true for

Introduction Our goal was to build a brain-computer interface using an AVR microcontroller. We decided that the least invasive way of measuring brain waves would be using electroencephalography (EEG) to record microvolt-range potential differences across locations on the user’s scalp. In order to accomplish this, we constructed a two-stage amplification and filtering circuit. Moreover, we

Introduction “A wireless mouse unit that requires no flat surface by using ultrasonic positioning.” For our ECE 4760 final project,we have designed a surface-less mouse interface using ultrasonic transmission as our final project in this class. The idea is to have a ultrasonic transmitter as a mouse, which represents the mouse’s position in space, with

Introduction Our project is building one set of NFC module including a NFC transmitter and a NFC receiver both using ATmega1284p microcontroller. We will be using coupled coils to transmit message modulated by a high frequency carrier, whose frequency is the standard frequency for Near Field Communication (NFC) – 13.56MHz (Wikipedia, 2013). In our project,

Introduction A modern-day twist on the classic theremin musical instrument. This project uses two IR sensors and the ATMEGA1284P microcontroller to create an inexepensive, easy-to-use theremin. The theremin is a musical instrument which is controlled by the electromagnetic field your body body produces naturally. One hand is used to control the volume of the instrument,
