After buying a new car that didn't have a trip computer to display fuel consumption statistics, open hardware hub member "winneymj" decided to make his own version based around an Arduino-compatible circuit. This is possible with some vehicles that have what is known as a CAN-BUS connector. The CAN-BUS is an automotive data bus that carries information between various devices in vehicle, such as the engine management computer, door locks, HVAC and so on.
