The Bat Hat Using Atmega1284

Introduction "An ultrasonic range-finding hat with variable haptic feedback for obstacle detection." -Project Sound Bite For our ECE 4760 final project, we designed and implemented an ultrasonic range-finding hat that uses haptic feedback to alert its wearer about obstacles in his or her path. The hat is equipped with an ultrasonic transmitter/receiver circuit, which is capable of emitting short pulses of u ...

Ultrasonic Pathfinder Using Atmega1284

Introduction: Our final project for the ECE 4760 course consists of a wearable device to provide aid for the visually impaired. An ultrasonic distance sensor located on a hat collects data of the surrounding environment scanning the area ahead of the user, and uses this data to give an audio feedback through stereo headphones. Using the principles of human sound localization this feedback provides informati ...

Acoustic Wayfinder Using Atmega1284

Our acoustic wayfinding device utilizes ultrasonic range finders and haptic feedback to facilitate indoor navigation for the visually impaired. The technique of acoustic wayfinding uses auditory cues, such as sounds from the natural environment or sounds created artificially, to determine an individual's surrounding physical space for the purpose of navigation. Our device is an automated and subtle implemen ...

Acoustic Impulse Marker Using Atmega1284

Introduction "A device that tracks sound impluses with a three microphone array" We designed and build a 2-dimentional Acoustic Impulse Marker system which is capable of detecting a sharp sound anywhere in its vicinity and precisely marking its source vector with a servo based pointer. Our system has a full 360 degree range, and is extremely effective at marking the source of sharp sounds to within 5 degree ...

Stabilized Gimbal System Using Atmega1284

This webpage describes the development of a Stabilized Gimbal Control System for the CUAir team, Cornell University's Unmanned Air Systems Team. The Stabilized Gimbal Control System will help the CUAir team compete at the Association for Unmanned Vehicle System International (AUVSI) Student Unmanned Air Systems (SUAS) Competition. The system developed will help the team accomplish the off-axis target imagin ...

Pushup Trainer Using Atmega1284

For our ECE 4760 final project, we choose to develop an electronic push-up trainer that could monitor people's movement, provide training package to optimize their push-up exercise and body health. A distance meter will be used to figure out whether the posture of the person is correct or not, and the touch screen used will be either an input and output device. It will take command and push-up input from us ...

Servo-Controlled Fire Extinguisher Using Atmega1284

Introduction We have created an autonomous, servo-controlled fire extinguisher that is capable of aiming photo sensors and a water nozzle along two axes to detect and extinguish candle fires a short distance (about 1 ft.) away using a small burst of water. Our inspiration originally came from thinking about an automated toy sentry turret that could fire at intruders (like a NERF® gun), but given ECE 4760’s ...
