Introduction There are very few ways to improve one’s skills in conducting a live band. Practicing by conducting a real band requires coordination of many people and conducting along to pre-recorded songs does not provide feedback on the accuracy of the conductor’s selected tempo. The system we designed uses a glove with an accelerometer to […]

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

Introduction Smart home technology has been surging in popularity over the past decade. According to a recent poll, 46% of consumers believe that it is important that their current or next home has smart technology. Many smart home technologies are expensive to implement and require a third-party company to monitor and support the system. We

For our 4760 final project, we built a virtual bowling game interface on a black and white Television in which the ball can be controlled by the glove which has the flex sensors and the accelerometer attached to it. There are 5 flex sensors on the glove to detect the ball grasped and the ball
For our ECE 4760 final project, we designed and built a bicycle dashboard which displays the cyclist’s pedaling power, speed, cadence, and distance to enhance training. The major motivation of this project was to replicate a commercial product at a dramatically reduced price point. A commercial power meter costs around $1000 for just the instrumented
ukule-LED is a ukulele with LEDs embedded in its fretboard. These LEDs can light up in configurations corresponding to different chords, which can aid the ukulele player in learning how to play certain chords, or can act as a chord reference for a more advanced player. ukule-LED has two modes of operations. First, in “play”
Introduction This project visually displays the frequency content of an audio signal using an 8X3 grid of LEDs. A microphone and amplifier collect analog audio input which is sampled digitized using the MCU’s analog-digital converter. The samples are buffered and and a 32 point discrete cosine transform is performed in real time to obtain 32

Introduction For our ECE 4760 final project, we implemented an interactive CPR training dummy which can coach the trainees through the CPR process with a LCD to display instructions. The prototype CPR training dummy built is a budget-friendly one that contains a re-programmable Atmel ATmega1284 microcontroller and other hardware components so that it can interact

Introduction For our final project, we have decided to use the microcontroller provided to make a device which would measure body fat percentage of one’s body. The basic principle behind this project is known as bioelectrical impedance analysis. This technique uses a small alternating current flowing between two electrodes attached to skin surface to determine

we designed and implemented a speaker recognition device that acts as a lock triggered by the sound of your voice saying a specific passcode. The implementation uses hardware filtering from a microphone and many signal processing concepts in software. All software and matching is implemented in the ATmega1284p. The lock has two modes: training and
