Title says it all, we can’t get enough of people doing cool car stuff with their Raspberry Pi’s. Each one is a little bit different and have a little different purpose. So up is Keith’s Toyota Echo. Keith is going green, he wants to watch the environment and his wallet.
So he’s got his Raspberry Pi, an OBD-II sensor, and a Nokia LCD. He’s written an app in python that reads his vehicle speed and mass air flow sensor. From that he is able to calculate his estimated fuel consumption at that specific point in time. He’s logging this data in a SQLite database and displaying it in real-time on the LCD. Nice job Keith.
