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. […]

n our final project, we designed an electronic multifunction instrument with a LCD touch screen and a microphone. The user can play three kinds of instruments on it — xylophone, flute and piano. Each instrument has a different interface and timbre. The piano part has a record/replay function which can echo the song previously played

Summary “Enabling secure storage capabilities for sensitive data through standardized methods of encryption or multiple agent distribution.” Our group chose to implement a secure form of storage for sensitive information such as passwords or identification numbers. This is modeled after Shamirs secret sharing algorithm. It allows us to distribute information regarding the secret key among

Introduction In this project, ultrasound around 24kHz was used to detect movement near an object. Waving a hand or other solid object near the source of the ultrasound (speaker) causes a shift in the frequency of the sound, which is then detected by a microphone. We detected characteristic shifts in frequency to determine whether motion

Motivation We design a smart home control system which allow people control their home devices by voice command at home. This is a wireless, voice control system. People could control almost all the facilities at home including lights, fans or even back ground music. Right now, the basic function of lights control, fan control and

Introduction Pulse Oximeter is a non-invasive medical diagnostic device used to detect the oxygen saturation of the blood. Heart rate meter detects the number of beats per minute of the patient, normally referred to as bpm. The pulse oximeter is designed using an infrared and a red LED, projected alternatively on the finger and detection

Introduction Robo-SLR provides a remotely controllable stand for a Canon EOS 550D DSLR camera, allowing for adjustable tilt and pan functionality along with the ability to remotely view through the camera’s viewfinder and take photos. An ATmega1284 microcontroller is used to control camera functions as well as tilt and pan over a wireless bluetooth connection

Our project is inspired by the commercial product, PicoDopp, which uses a similar scheme for foxhunting. Foxhunting is a contest where participants try to locate a transmitter, called the fox, simply by monitoring the signals it transmits. Typically this is done using highly directional antennas — antennas that only receive signals from one direction. However,

Customer’s Voice “Hello, I am interested in a race car logger than will be able to display and log crucial information during autocross and track events. I am interested in tracking vehicle speed, RPM, engine coolant temperature and lateral g-forces. Ideally, the data can be stored on a SD card which can later be read

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
