The [http://raspberrypi.org Raspberry Pi] is a $35 computer board designed to provoke and enable experimentation in programming and computer technology. It can be used as a simple desktop computer, but it also makes an excellent controller for embedded and robotics projects. It does not come with a case, and although many different cases have been designed and are available for the Pi, they are not suitable for demanding environments.
