Carputer – AVR based car computer
Probably it is always interesting to modify things you are passionate about. As you know – car panel doesn’t show all information you would like to know during journey. Let’s say you want to follow fuel consumption, display temperatures and control air conditioning, and have centralized control of many other devices like electrical windows, etc.
So here is a nice project for this. It uses AVR microcontroller that is equipped with various sensors and LCD display which shows quite a bunch of info like momentary fuel consumption, momentary speed, journey time, passed distance and many average indicators. First working project version can be found here. Probably there will be another with more improvements.
