Huawei K3V2 Based MediaPad 10 FHD Tablet Hands-On Video

Earlier this year, Hisilicon – a subsidary of Huawei – unveiled the K3V2 quad-core Cortex A9 processor at Mobile World Congress and Huawei showcased the Ascend Quad D Android 4.0 smartphone as well as an high-end Android ICS Tablet based on this processor called Huawei MediaPad 10 (which nobody was allowed to use). This tablet features a 1920×1080 display with a 10-point touchscreen, 1GB RAM, 32 GB Flash and a 8MP rear camera together with a 1.3MP front camera. It also comes with a 6,600 mAh battery and is only 8.8mm thick. Huawei brought the device at CTIA 2012 and Engadget could shot an hands-on video of the MediaPad 10 FHD. No release date nor pricing is available, nevertheless it’s listed for 699.99 USD on Android-Sale.com.

Tizen OS Running on Samsung Smartphone Reference Design (Video)

After Tizen 1.0 (codenamed Larkspur) release last week, a Samsung prototype was showcased at the Tizen Developer Conference on May 7-9 in San Francisco. The Samsung prototype fearures a 4.65 inch 1280 x 720p HD Super AMOLED display and runs Tizen on an Exyons? 1.2 Ghz dual core Cortex A9 chip with 1 GB of RAM. Vaibhav Sharma of The Handheld Blog, who has tried this developers’ reference design at the conference, shows us the main menu (similar to TouchWiz), system settings, the web browser (which scores 408 on HTML5Test.com), the picture gallery, the music player, youtube video playback etc… and it looks pretty smooth as shown in the hands-on video below. This is just a prototype, so performance will most likely be further improved once a Tizen smartphone is made available to the general public.

SCUBAPRO-UWATEC Meridian Dive Computer Powered by EFM32 Gecko Cortex M3 MCU

SCUBAPRO-UWATEC and Energy Micro have unveiled the SCUBAPRO Meridian dive computer powered by Energy Micro EFM32 Gecko MCU. Meridian is a sophisticated dive computer in a watch design, powered by a CR2032 lithium battery. The companies claim the Meridian is the world’s first 32-bit dive watch-computer. It can operate at depths of up to 120 meters, incorporates an advanced diving algorithm, performs multi-gas decompression and features an heart rate monitor that enables adaptive workload calculations. The watch computer can be used both during diving, configured to display a variety of dive information including depth, dive time, decompression status and water temperature, and above the surface where it handles remaining desaturation time, no-fly time. Its built-in thermometer and altimeter can also be used for mountain treks. The MCU used in the Meridian is the Energy Micro EFM32G890 Gecko, a 32MHz 32-bit MCU based on ARM Cortex-M3 consuming 180µA/MHz is active mode […]

Build Your Phone Android Distro with CyanogenMod Compiler 0.4 GUI (Cmc-pygtk) for Ubuntu

Lithid, a member of XDA Developers Forum, has recently released the 4th version of a GUI tool (Cmc-pygtk) to build Android for a given smartphone as long as it is supported by CM. The CyanogenMod Compiler is supported by Ubuntu 10.04 32/64-bit and greater, and you can either download a deb file or build it yourself by following the instructions below: Install dependencies:

sudo apt-get install build-essential devscripts ubuntu-dev-tools debhelper \
dh-make diff patch cdbs quilt gnupg fakeroot lintian pbuilder piuparts \
flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools \
libncurses5-dev  zlib1g-dev openjdk-6-jdk pngcrush schedtool

sudo apt-get install build-essential devscripts ubuntu-dev-tools debhelper \

dh-make diff patch cdbs quilt gnupg fakeroot lintian pbuilder piuparts \

flex bison gperf libsdl1.2-dev libesd0-dev libwxgtk2.6-dev squashfs-tools \

libncurses5-dev zlib1g-dev openjdk-6-jdk pngcrush schedtool

Clone the source tree:

git clone git://github.com/lithid/Cmc-pygtk.git

1	git clone git://github.com/lithid/Cmc-pygtk.git

Generate a gpg key:

keygpg --gen-key

1	keygpg --gen-key

Delete the changelog or dpkg will use lithid key instead.:

cd Cmc-pygtk
rm os-versions/common/changelog

1 2	cd Cmc-pygtk rm os-versions/common/changelog

Edit the EMAIL field in the Makefile and replace it with the one used to generated the gpg key. Build it for your version of Ubuntu. For Ubuntu 12.04 32-bit:

make cmc-12.04-32

1	make cmc-12.04-32

And install it:

cd out
sudo dpkg -i cmc-12.04-32-v0.4.deb

1 2	cd out sudo dpkg -i cmc-12.04-32-v0.4.deb

Before using CyanogenMod Compiler (CMC) is installed, you need to install google repo tool:

curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo &gt; repo
chmod a+x repo
sudo mv repo /usr/local/bin/repo

curl https://dl-ssl.google.com/dl/googlesource/git-repo/repo > repo

Detect Mobile Devices with WURFL in Websites and Mobile Apps

When designing a mobile application or webpage, you may want to know exactly to know what devices access your site or run your application for example to differentiate automatically between desktops, laptops, tablets and smartphones and provide a user interface which is appropriate for a given screen size. This can be achieved with WURFL (Wireless Universal Resource FiLe), a Device Description Repository (DDR). This software component maps HTTP Request headers to the profile of the HTTP client (Desktop, Mobile Device, Tablet, etc.) and provides a description of the capability of the device that made the request. WURFL repository is an xml file (wurfl.xml – Direct links to version 2.3.1: wurfl-2.3.1.zip or wurfl-2.3.1.xml.tar) containing the definition of thousand of devices which can be access using the WURFL APIs. Several large Internet companies such as Facebook and Google are using WURFL, and ScientiaMobile, the company behind WURFL, claims that it is the […]
