At the end of academic year ECE476 Cornell University students produced about 40 new projects mostly based on Atmega32. As every year students have their responsibility to choose their own final project. So there you can find various interesting ideas and designs including video games, robots, MIDI synthesizers, clocks, speech recognitions and so on. Projects here are accumulated since 1999 Spring(over 200 older projects). So you can surf inside pretty big knowledge base and find ideas, solutions and inspiration for your own designs.
The goal of this project was to build affordable mobile tracker. Device can be put in a car where it can trigger an alarm when car gets stolen. Device itself is very simple as GSM module already comes with GPS module (GM862) built in. Alexander Weber connected this module to Atmel’s Atmega8 microcontroller (circuit) and communicated using serial modem communication protocol. Device can send text SMS message with device GPS position data. Project author provided only eagle circuit.
