Students at NTNU has since 2008 participated in the international student competition Shell Eco-marathon, held annually in Europe, Asia and America.The goal is to build energy efficient cars that run as far as possible, in as little energy as possible.
As a central device of this drive system is much mention computer Rasperry Pi , offered by the charity Raspberry Pi Foundation.The hardware, which largely consists of a circuit board with an ARM-based processor and various ports, costing from $ 25 plus tax.The first version of the device went on sale last year and has since been sold to more than one million copies , among other IT enthusiasts.But the founders of the project has also had a desire that it is used in teaching.
In the students' electric car is Pi-a connected to both a touch screen and the modular drive system.Jostein Furseth, studying for Master of Engineering Cybernetics, explaining that the team has developed a module that acts as an interface between Pi and on your car's own system.This mobile phone is connected to Pi-a-pin GPIO (General Purpose Input Output).
- The module takes care of the communication with the rest of the car system over CAN-bus (Controller Area Network) and mobile telephony (GSM / GPRS).In addition, it handles a number of practical small tasks like reading of buttons, analog signals, indicator lights and digital control of lighting systems.These different modules are the team from scratch, of us students, says Furseth.
- The reason for choosing the Raspberry Pi, was that this can run Linux, which makes it possible to program in high level language like Python.Since most touch monitors come with HDMI / DVI connectivity, the Pi-an easy to use, since it has these video interfaces, says Furseth.

A total of eleven modules that students make to the DNV Fuel Fighter.This includes a module which protects the system against surges, one that measures how much power is taken from the battery and how much is produced during the vehicle's solar panels.
It also developed a module that transmits the same information that the driver has access to a remote computer where the rest of the team can get continuous updates on how the car performs on the track.

According Catrine Hernes Hovland, as media and public relations manager for the year DNV Fuel Fighter team, the availability of information gold.
- There are small adjustments to be to get to push the car to perform better.The more information the system is able to collect, the better, says Hovland to digi.no.
She says that this year's team will have to compete against twice as many cars as last year.
- This is because the electric vehicle and solar classes of competition are combined into one class.To be among the top five will be more difficult.That said, we have made many improvements to the DNV Fuel Fighter.Magnet motor is powerful, and a number of other tweaks contribute to an even better car overall.Therefore, we have high hopes of making it as good, or better, than last year's car, says Hovland to digi.no.

This year's competition conducted in in Rotterdam on 15to 19May and the 30thin the series.The first was held in 1939 in USA.The competition has been held annually for the past 20 years.
On competition days the cars running ten laps around a roughly 1.6-kilometer track in the center of Rotterdam.The average energy will then be calculated, and the car with the best results wins the prestigious Eco-marathon trophy.This year a total of 262 participating teams from 20 countries.
DNV Fuel Fighter participate in the Urban Concept category, which means it focuses on practical design.The second main category, Prototype, focuses on maximum efficiency.Each of the two categories are divided into seven, based on the fuel vehicles use.
