Every year, teams of students from universities around the world compete in the Formula Student auto racing competition. One team used a Raspberry Pi to monitor sensor data on the vehicle and send the results to the pit crew through a wireless connection. We'll show you how they did it.
Formula Student is an international competition in which qualifying student teams build and deploy a race car according to Formula SAE rules. The competition spans the disciplines of engineering design, cost analysis, and business presentation and provides hands-on experience designing for acceleration, autocross, endurance, and fuel efficiency.
The team known as joanneum racing graz built a Raspberry Pi into the race car to collect vehicle data and send it back to the pit crew over a wireless connection. To achieve this goal, they plugged the Pi into the CAN bus, a built-in bus found on many vehicles that facilitates communication among the on-board devices. The Pi then received and processed the vehicle data, posting it to web page using an Apache web server running on the Rasp Pi system. The support team then used a web browser to connect to the web server running on the Pi and read the device data in real time.
The rest of the story is all in the details.

University students take the Raspberry Pi to the streets, using it as a data logger for bicycles and motorcycles.
The fourth incarnation of the Pi and More conference brought Raspberry Pi fans together for a day of lectures, workshops, ideas, and experiences.
From all over Germany, Raspberry Pi fans went to Trier in mid-June for "Pi and More 3." For a whole day, visitors of all ages enjoyed lectures and participated in hands-on workshops.
A recent trend shows several data centers are offering professional hosting services for Raspberry Pis. What is this all about?
We show how to build a remote control for a toy car built out of Lego parts, a Rasp Pi, a game pad, and a Java program.
