Real-Time Pitch Shifter. Using Atmega

Leave a Comment / Using Atmega / Tech Master

Introduction “A device that pitch-shifts voice in real time” For our final project, we attempted to implemented a real-time vocal pitch shifter. The system was designed to work as follows: a user speaks into a microphone, their vocals are processed using a pitch shifting algorithm, and the resulting signal is output through speakers. All of

Digital Compass Using Mega 32

Leave a Comment / Using Atmega / Tech Master

I. Introduction The goal of this project is to build a digital compass that displays both the direction and cardinal points on a television. Other functionalities were added to complement the sensor interface, such as, temperature display, magnetic declination input and disability option. At the highest level, this project involves acquiring two output readings from

Multisensor Data Transmission Using Atmega32

Leave a Comment / Using Atmega / Tech Master

Introduction For our final project we built a prototype of a circuit intended for a picosatellite that measures temperature and acceleration, sending the information wirelessly back to a base station receiver. The N-Prize is an amateur rocketry competition challenging groups to launch a very small (10g-20g) satellite into orbit for less than $2000, and track

Optical eye tracking Using Atmega644

Leave a Comment / Using Atmega / Tech Master

Introduction We have endeavored to develop a means by which eye gaze can be detected. This goal was achieved using the same principles learned in Lab4, where we recorded the motor speed of a small hub fan using the combination of IR emitter plus phototransistor, henceforth referred to as an emitter-phototransistor pair. High Level DesignSeveral approaches

Flexicopter Using Atmega644

Leave a Comment / Uncategorized / Tech Master

Introduction The purpose of our project is to control a toy helicopter using flex sensors attached to a glove. The flex sensors are intended to replace the remote control that is generally used to fly the helicopter. Additionally we also created another mode which will allow us to use an accelerometer to control the forward

Radio Station Tracker Using Atmega644

Leave a Comment / Using Atmega / Tech Master

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,
