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 […]

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 […]

Android 4.0 Running on Raspberry Pi with Hardware Acceleration

Eben of the Raspberry Foundation announced that a developer (Naren) has been working on a port of Android 4.0 for the Raspberry Pi, and the port already appears to be a an advanced stage with hardware-accelerated graphics and video working smoothly. The only major issue is the lack of support for AudioFlinger. The demo below shows Android 4.0 running in the Pi without audio as it’s not implemented yet. The UI is relatively smooth, and video playback and YouTube video streaming work pretty well. This is quite impressive considering the Raspberry Pi has less than 256 MB of memory available to the system, and I suppose they must have made some compromises to make this work. Moreover, I would expect that many applications won’t run properly due to the ARMv6 processor and low system memory. The source code and binary release are not available yet, as this port uses a […]

84 MB Minimal Raspbian ARMHF Image for Raspberry Pi

Many embedded systems applications do not require a desktop environment or graphical interface on the screen (e.g. server), and you may want to only install the files you really need on the SD card either to reserve as much space as possible for data and/or your program or to reduce costs. After searching for a minimal image based on Raspbian ARMHF distribution for the Raspberry, I could only find Linux Systems minimal image based on the Alpha version of the Raspbian Wheezy. Their compressed image is 109 MB in size, has a custom kernel, sshd and ntpd are enabled, but the wireless tools were deleted, and at the time the swap was located in another partition instead of a file inside the rootfs. The uncompress rootfs is about 414 MB (as reported by df -h when mounted as a loop device). I decided to prepare a minimal image myself based […]

Raspberry Pi Releases Raspbian SD Card Image Based on Debian Wheezy ARMHF

The Raspberry Pi foundation announced the very first stable release of the Raspbian distribution, which is based on Debian 7.0 “Wheezy” armhf rootfs in order to take advantage of the FPU in Broadcom BCM2835. This distribution offers up to 40% performance improvement on several tasks, and for some specific tasks such as MP3 encoding is can boost the speed by nearly 6 times thanks to hard-float support. It is now the recommended distribution for the Raspberry Pi, runs LXDE environment, and comes with Midori browser, development tools and example source as per the previous Debian distros. omxplayer by gimli (XBMC developer) is also pre-installed in the image, and will allow you to play videos using hardware acceleration. You can download Raspbian via: Bittorrent – 2012-07-15-wheezy-raspbian.zip.torrent HTTP – 2012-07-15-wheezy-raspbian.zip The default credentials are pi / raspberry. Adam Armstrong has run some benchmarks to compare Raspbian (armhf) with the previous Raspberry Pi […]

HackBerry: AllWinner A10 Development Board with 1GB RAM

After the Raspberry Pi, the Gooseberry, here comes the HackBerry. This is another AllWinner board similar to the Gooseberry, but which Ethernet, a full sized USB ports, an IR sensor and 1GB RAM. Here are the board specifications : SoC – AllWinner A10 System Memory – 1 GB RAM Storage – 4GB Flash + SDHC slot USB – 2x USB 2.0 ports Connectivity: 10/100Mbit Ethernet Wifi – 802.11 b/g/n Video Output – 1 x HDMI + 1x Composite Audio I/O – Headphone + microphone IR sensor The board runs Android 4.0, but since it’s an AllWinner device, you can run what you want. In a way it’s similar to the Mele A1000, except it has more memory, but lacks SATA, VGA output and has one less USB port. I can’t see the serial port pins on the PCB picture either. There is pricing information or availability yet, as Jasbir only […]
