The Raspberry PI laptop computer reported in Elektor News was created using a 3D printer for the case, model B+ Raspberry PI, laptop keyboard, track-pad, WiFi, battery and 13.3″ HD screen. The battery lasts 6 to 8 hours.
More than one operating system can be loaded to the same Raspberry PI SD card using the NOOBS installation files. This allows easy experimentation and evaluation with different operating systems.
In the article on booting multiple operating systems, Raspbian, RISC OS Pi and Arch Linux are loaded onto a single 16Mb SD card to show how easy it is to boot multiple operating systems on the RPI.
The Raspberry PI Model B Plus is now available. The first thing to note about the B+ model is that you will need to load your operating system of choice to a micro SD card, so don’t forget to order one if you don’t already have one.
Some of the other major changes are:
- There are now 4 USB host ports on the board
- The I/O pin header now has 40 pins instead of 26 pins
- The new micro SD card socket now latches the card: push the card in to lock it in the socket, push the card again to unlock it
- The composite RCA socket has been removed
