OBD-II Autocross/Track Data Logger for BMW E36 M3 Using Atmega644

Customer's Voice    top “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 on a computer. An LCD display showing two or more parameters will be extremely usef ...

Brain-Computer Interface Using Atmega644

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 used the built-in ...

Digital Saxophone Using Atmega644

Abstract My final project was the design of a digital saxophone which can reproduce the sound of an actual saxophone through digitally synthesized electrical waveforms. The digital saxophone consists of a microphone to sense the user blowing into a mouthpiece, push-buttons to control the note to be played, and the Atmel644 Micro-Controller which processes the inputs and produces the digital output that soun ...

Virtual Saxophone Using Atmega644

Our ECE 4760 final project was to create a virtual saxophone that uses Direct Digitial Synthesis (DDS) to synthesize the output notes. Pushbuttons are connected to a PVC pipe to mimic the saxophone's mechanical structure, and a microphone that detects noise is used to determine whether or not the user is blowing into the device. We decided to do this project because we enjoyed the ECE 4760 Lab on DDS and wa ...

Auto-composing keyboard Using Atmega644

Project Overview We designed an electric piano that automatically composes a piece of music for the ECE 4760 final project. All the user need to do is to select a mood of the music and play two notes upon which the music is based, and then he can just lie down and enjoy the music created for him. He can also choose to train the piano by first playing several pieces of music he is fond of. The piano would th ...

MicroKart 644 Using Atmega644

The Micro Kart 644 is a mobile device that provides additional capability to the traditional RC car experience. Allowable functions are recording multiple tracks, which consist of all user controls sent to the car over a 25 second interval, and replaying the tracks so the cars replicate the movements made during the recording. In addition, we interfaced with not one but two cars, which allows the user to mi ...

Touchpad Figure Recognition Using Atmega644

Our project implements a touchpad input system which takes user input and converts it to a printed character. Currently, the device only recognizes the 26 letters of the alphabet, but our training system could be easily generalized to include any figure of completely arbitrary shape, including alphanumerics, punctuation, and other symbols. A stylus is used to draw the figure/character on the touchpad, and t ...
