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.
The name for this laptop is “PI-TOP”, you can read more about it on the Pi-Top website and also follow the project on Facebook for updates.
Learn to write your own sketches for the Arduino in this multi-part course. No previous programming experience is needed.
The Arduino programming course consists of the following parts:
Each new part of the course will be added to his blog post as it becomes available.
You may find the Arduino Language Reference on the Arduino website helpful during the course.
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 Atmel SAM4N Xplained Pro evaluation board contains a ATSAM4N16C microcontroller. The board itself is rather basic with only one user programmable LED and one user programmable push-button switch (the second switch is a reset switch). Pins of the microcontroller are available on headers on the board.
An on-board Embedded Debugger is included on the board, so that no external tools are required to program or debug the ATSAM4N16C.
The video below shows the evaluation board being unpacked.
Some features of the ATSAM4N16C microcontroller are:
- ARM Cortex-M4 that can run up to 100MHz
- 3 USARTs and 4 UARTS
- Real Time Clock (RTC) with calendar and alarm features
- 10 bit ADC and DAC
- 1Mb Flash memory
- 80kb SRAM
- The usual SPI, TWI, timers, PWM, etc.
The ATSAM4N16C does not contain any USB ports, Ethernet or external bus.
