Introduction The CCDImager is an Atmel Mega32 microcontroller driven imaging system that uses a Charge-Coupled Device (CCD) optical sensor to capture a still image. The purpose of this project was to design a basic imaging device from first principles. While brainstorming for ideas for the final project, we came across several varied applications of microcontrollers, […]

Introduction: Our project is a serial port-controlled, high resolution color television picture display. We divided the project into the image transfer and storage portion and the television display portion. We opted for an RS-232 port for picture transmission because it involves a relatively simple, well-known protocol that will allow us to change the picture on

Introduction Overview SecureLED is an optical access control device which replaces current RFID or Magnetic Strip technologies with a cryptographically secure, contact-less device which communicates over commodity Light Emitting Diodes (LEDs). Project Summary This project started with one central premise: current physical access control systems are insecure in fundamental ways. We sought a way to

Introduction Our final project is a programmable, self-playing xylophone with random melody generation and a pitch detection based interface. From early mechanical devices to todays musical greeting cards, history has seen numerous examples of automated music machines. This project represents a quick, modern take on that tradition with several additional features. We designed and implemented

Introduction This project implements a wireless surface electromyograph that displays the signal using a television as an oscilloscope. Electromyography detects the electrical signals that the human body generates to contract muscles. Detecting very low voltages in the milliVolt range on the skin surface is not a trivial task. As shown in figure 1, EMG signals
