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 […]
AllWinner Linux-sunxi Community Presentation and Status Report – FOSDEM 2014
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 […]
How to Build and Run Tizen 2.0 on AllWinner Boards – FOSDEM 2014
Leon Anavi has spent some time building and running Tizen for Olimex A10s-OLinuXino-MICRO board based onAllWinner A10s cortex A8 processor, and gave a short presentation at FOSDEM 2014 showing the main steps involved in the project. The final result is basically a non-portable Tizen tablet with a main board connected to an LCD display. If you have an LCD screen, you could also use a monitor (VGA/HDMI) instead. After a short description of the hardware, and explaining it should also work on other AllWinner platforms such as Cubieboard, Leon gave a few no-nonsense recommendations he learned from his mistakes: Get a USB serial board for debugging Use recommended accessories from the manufacturer such as power supply or LCD display to make development easier Buy a board that can boot from micro SD or SD card, again for ease of development If something does not work… Restart the board! 🙂 In […]
