ARM Interview about Cortex A17 Processor [Video]

When ARM announced their new Cortex A17 core, I could not quite understand why they would release another core with performance and features somewhat similar to Cortex A12 and Cortex A15. Charbax interviewed Nandan Nayampally, ARM VP of Processor Marketing, at Mobile World Congress 2014 and everything is much more clear now. Cortex A17 is based on A12, but adds support for big.LITTLE processing support with Cortex A7, and further improves performance. In some work loads Cortex A17 can currently match Cortex A15 performance, and by 2015, Cortex A17 will have performance similar to A15, and replace it in mid range devices as it has a lower footprint and lower cost. High-end products will switch to 64-Bit with Cortex A53 or A57 next year. The interviewee did not say this explicitly but it could be many companies will simply skip Cortex A12, and directly use Cortex A17, just like Rockchip […]

Yeelight Blue and Yeelight Sunflower Bluetooth Low Energy and Zigbee Smart Light Bulbs for iOS and Android

When it comes Smart light bulbs, which can be dimmed and made to change color, the most popular product must be Philips Hue, using the Zigbee protocol, which you can control via iOS and Android devices though a Zigbee gateway, and costs about $60 on Amazon. Alternative have started to show up such as iLumi Bulbs, with Bluetooth 4.0 Low Energy (BLE) technology, that you can control with recent iOS and Android 4.3+ device without the need for a gateway, but with a price starting at $89. If you’re looking for cheaper alternatives, you’d have to turn to Chinese companies such as Yeelight which provides both Bluetooth LE and Zigbee light bulbs, respectively called Yeelight Blue and Yeelight Sunflower. Yeelight Blue does not require a gateway, but you’ll need a smartphone or tablet that supports Bluetooth 4.0 Low Energy. Recent iOS 5.0+ devices should support it. If your Android device […]

DIY Farm & Garden Automation with Arduino and APDuino Project

You would like to start to grow your own vegetables but you don’t really have enough place and/or time to take care of your garden. No problem! Just go vertical and automate your garden with an Arduino Mega, an Ethernet shield, and lots sensors and valves. That’s basically what Rik Kretzinger, who grew up on a Christmas tree farm, and has a major in horticulture, has done at his home. This whole system use a farming technique called aquaponics, mixing aquaculture (raising fish in tanks) and hydroponics (cultivating plants in water), and except planting and harvest, is mostly automatized. The hard part is to set it up. The firmware is based on APduino “Internet-of-growing” open source project that runs on Arduino Mega to gather data from sensors (humidity, temperature, pH, light…) and control the valve. Rik’s system also upload data automatically to Xively cloud so that he can monitor his […]

Google’s Project Tango Phone Prototype Generates Real-time 3D Maps

Google ATAP (Advanced Technology and Products), the team who is currently working on Project Ara for Google, and recently moved from Motorola following the acquisition by Lenovo, has also been busy on another project called Tango, which centers around a phone equipped with cameras and sensors capturing 250,000 data points per second to track motion and generate 3D maps in real-time. The prototype is 5” phone with hardware and software customization designed to simultaneously track the 3D motion of the device, and creating a 3D map of the environment. The device runs Android and includes development APIs to provide position, orientation, and depth data to standard Java, C/C++ Android. This is still early development, but the team imagine the technology could be used to easily create a 3D map of your home, facilitating furniture shopping. Other usa cses include indoor navigations, visually-impaired aid, and product location in a store. Augmented reality […]

Try Ubuntu Touch on Your Computer with Ubuntu Touch Emulator

Canonical has just announced Meizu (China) and Bq (Europe) will be the first manufacturers to launch Ubuntu Touch phones at the end of 2014. But if you want to try Ubuntu Touch, and don’t own a Google Nexus 4 or 7, or simply don’t want to flash Ubuntu Touch to your devices, you can do so using Ubuntu Touch x86 Emulator in your computer running Ubuntu , or in an Ubuntu Virtual machine in Virtualbox or VMWare. The emulator has been available since last November, but Ricardo Salveti announced an updated version, the first public preview, with the following changes: Better TLS handling (not using the Android slots, but using pthread_set/getspecifics instead) Qt packages compatible with OpenGL ES 2.0 available at https://launchpad.net/~rsalveti/+archive/qt-gles-test It has been tried on Ubuntu Trusty (14.04), but I could run it just fine on Ubuntu Saucy (13.10), by following the instructions below in a terminal: Download […]

Intel Bay Trail Graphics Overview – FOSDEM 2014

Bay Trail SoCs are new low power Intel ICs for tablets (Bay Trail-T, Z3000 series), mobiles (Bay Trail-M, N2800, N2900 and N3500 series), desktops (Bay Trail-D, J1800, J1900 and J2900 series) and embedded / industrial platforms (Bay Trail-I, E3800 series). Many Atom processors used to features PowerVR GPU, but it has now been replaced by Intel HD graphics in Bay Trail SoC. Jesse Barnes, working at Intel on software and drivers for Intel graphics devices, gives a presentation about Bay Trail SoCs with a focus on graphics. After an overview, and some ARM bashing regarding performance (Nvidia Tegra 4 and Qualcomm Snapdragon 800), and even power consumption (Tegra 4 only), he describe further details about Intel HD graphics found in the new Intel processors. Everything is basically in mainline, and you’ll need Linux 3.10 or greater, Mesa 9.2 or greater, and libva 1.2.1 or greater for proper support. Some initial […]

Oliver Schinagl, a member of linux-sunxi community working on open source kernel and bootloader for AllWinner SoCs, has given a presentation of the community at FOSDEM 2014 to give an overview, and show what progress has been made to date. I’ll write a summary in this post, but if you want to watch the video and/or access the slides scroll down at the bottom of the post. After explaining what sunxi is, and introducing himself, he gave some information about AllWinner and their SoCs: Founded in 2007 in Zhuhai, Chiang now with 550 employees including 450+ engineers 15% market share in 2013 for tablet SoCs, only behind Apple. Products: F-series SoC (2010), A10 (2011), A13, A10s (2012), and A20 (2013). (cnsoft He skipped A31(s) and A80 here as they are not really supported by the community). They list “Open Source Source” and “GPLv3” in their marketing materials although they clearly […]
