Adafruit Launches Raspberry Pi Starter Pack for $69.95

The Raspberry Pi is supposed to be great for hardware prototyping, but you may not know where to start and/or depending where you live it might be difficult to buy the small components needed at a decent price. That’s where Adafruit Raspberry Pi starter pack comes into play. It includes a case, some cables and power supplies, as well as a breadboard and a whole bunch of components. The package includes: Adafruit clear acrylic Pi Box USB Micro-B Cable to connect the Raspberry Pi to a power source 5V 1A power adapter USB TTL console cable to be used to access the serial console. Useful to debug the kernel or if you run your device without display and/or network. 4GB SD Card Adafruit Pi Cobbler kit with GPIO cable for connection to the GPIO/I2C/SPI/Power pins. USB microSD card reader for loading the image onto the SD card. Large full-size clear […]

HardKernel ODroid-X Development Board Unboxing and First Boot to Android

I’ve just received the ODroid-X development board based on Samsung Exynos 4412 quad-core processor together with lots of accessories: WiFi-Modules Kit USB-UART Module Kit 16 GB eMMC Module 5V/2A Adaptor 10.1″ LCD Module (1366×768) BlueTooth Dongle Camera Module HDMI Cable Since there is quite a lot of things to cover, today I’ll just show some unboxing pictures, how to connect all those modules to the board and run Android pre-loaded in the eMMC module, and I’ll do a more detailed review with Android and Ubuntu in another post. I received the kit in a large box sent via EMS. Here’s a picture with the board and all accessories present in the Box. From top left to bottom right: 10.1″ LCD Modules, ODroid-X development board, HDMI to mini HDMI cable, micro USB to USB cable (for debugging), 5V/2A power supply for the board, 9V/1.5A power supply for the LCD module, WiFi […]

WordPress for Raspberry Pi using Nginx and MySQL

I’ve been wondering how the Raspberry Pi would handle WordPress. I’ve found some instructions using Apache 2, but this may not be the best server to use for this type of low-end hardware. nginx server requires less resources, and as it is what I already setup for this blog, I decided to give it a try on the Pi. I’ll provide all the detailed steps I followed below, but you can also download the compressed SD card image (113 MB), uncompress it and copy it to an SD card the usual way. After the system boots, find your Raspberry Pi’s IP address, type it in your PC’s browser, and you should see the page pictured below. If you want to login to the dashboard, the username is “admin” and the password “raspberry”. Instructions to Install WordPress on Raspberry Pi You can use your default Debian Linux distribution (e.g. Raspbian) if […]

RasPiComm – Raspberry Pi Expansion Board

Daniel Amesberger has designed a tiny expansion board called the RasPiComm to make use of the extension header of the Raspberry Pi board. It connects to the RPi in a similar way to the shields for the Arduino board. The board comes with the following extensions: RS-485 port – Mainly used to control stepper motors. RS-232 (‘serial’) port – It can be used to access the serial console over “/dev/ttyAMA0″ serial device, which can be very useful for headless systems. 5 inputs connected to an onboard joystick and screw terminals 2 outputs (5V) with LEDs (green and red) also connected to screw terminals I2C connection – There are plenty of things you can do with I2C connections (Sensors, RTC, …), and Daniel successfully connected a tiny 128×64 I2C OLED display. Real time clock (RTC) with backup battery – Very useful for offline use if you need to keep track of the […]

HackBerry AllWinner A10 Board is Now Available for $60

The Hackberry “development board” is now available for sale on Miniand. This board powered by AllWinner A10 processor comes in 2 versions: 512 MB RAM version – Available now for $60 1GB RAM version – Available by the end of the month for $65. Both boards features a 4GB Flash, a SDHC slot, 2x USB 2.0 port, 10/100 Ethernet, Wi-Fi, HDMI & composite outputs, headphone & microphone ports and a IR sensor. The good thing is that serial interface and FEL connectors will be soldered on the board for easy debugging and recovery. The FEL recovery port allows to reflash the board using Livesuit. As a side note, Henrik, a developer involved in Allwinner A10 software development, has done some work to reverse engineer FEL USB protocol, wrote a small program to enter into Livesuit mode with an SD card (Go to the bottom of the page section “Forcing FEL […]

AllWinner A10 Initramfs Support and Linaro 12.07 Image

An initramfs is a minimal root filesystem that is loaded at an early stage of the boot process, before the rootfs partition is mounted. This is optional but is now used by many Linux distributions such as Ubuntu in order to speed up boot time among others things. Up to recently, there was no support for this in the AllWinner A10 nightly builds, and there would be lot of error messages due to ureadahead process with Ubuntu, but I’ve changed that by: Using a boot.scr file (U-Boot Script) for each supported device in order to either follow the default init boot method or do an initramfs boot if uInitrd file is present in the FAT partition. Adding a script (a1x-initramfs.sh) to generate and install uInitrd initramfs in the rootfs. The initramfs can’t be generated at build time since the hardware packs are (mostly) distribution agnostic. If you want an initramfs, […]
