Ubuntu Edge Smartphone PC Hits Indiegogo

Canonical has announced Ubuntu for Phones and Ubuntu for Tablets at the beginning of the year, with the goal of bringing Ubuntu operating system to mobile devices, and transform high-end devices into the new PC when they are connected to an HDMI display. It turns out mobile phone manufacturers may not be ready to take the risk launching a completely new high-end platform to the market, so Canonical decided to leverage the power of crowdfunding but launching an Indiegogo campaign for Ubuntu Edge, a smartphone with hardware specs like no others, capable of running both Android and Ubuntu, and fully replacing your PC when docked. Ubuntu Edge Preliminary/Targeted Specifications: SoC – “Fastest Multicore Processor Available” System Memory – At least 4 GB RAM Storage – 128 GB flash Display – 4.5″ display with the best balance of resolution (720p), dynamic range and color accuracy, covered with sapphire crystal glass (Unscratchable, […]

Mediatek Smartphone and Tablet SoC Product Line (Mess) Explained

This week-end, I have been tipped about a $91 Mediatek MT8317 based 7″ Phablet, but I really did not know what to think about it as Mediatek seems to have so many SoCs, and really felt lazy trying to dig information about this. Yet, in the back of my head, I had decided to eventually make a post trying to clarifying Mediatek SoCs. This morning, I felt relieved not to have to spend hours investigating, as AndroidPC.es found an analyst paper doing just that, at least for recent and upcoming Mediatek processors. Mediatek Smartphone SoCs Roadmap MT6589 is certainly the most common SoC for cheap quad core smartphones, and starting this month, it will be available in MT6589M and MT6589T versions, the former with a weak video processing unit (VPU) and ISP, and GPU frequency, and the latter with higher GPU and CPU frequencies. Contrary to the table below, MT6589 […]

Fedora 19 ARM Remix R1 Release With Support for AllWinner A10, A10s, A13 and A20 SoCs

After releasing a stable version of Fedora 18 for AllWinner A10 and A13 in February, Hans de Goede, working at Red Hat and a Fedora contributor, has recently announced “Fedora 19 ARM remix for Allwinner SOCs” on linux-sunxi community mailing list. This released based on Fedora 19 for ARM together with linux-sunxi kernel and u-boot, adds support for A10s and A20 based devices, and 38 boards and devices are now supported. To give it a try, download the 665MB image:

then write it to an SD card (8GB or greater):

Where you have to replace [device] with your actual SD card device, e.g. sdc.Since u-boot is board/product specific, you’ll also have to update u-boot for your hardware. Remove the SD card, re-insert it, and run:<

The Little Black Box XBMC STB Gets Users’ Feedback, Becomes Available on Amazon

The Little Black Black Box (TLBB) is an set-top box running XBMC powered by AMLogic AML8726-M3 with 1GB RAM, 4GB Flash that comes with a dual sided RF remote control. The device became available for pre-order in April, and the first customers have started to receive the media player, one of them (flipfoelyfe) has uploaded a video, and posted some pictures. After initial issues setting up Wi-Fi (A bug seems to prevent the use of long passwords), his tweets about the device are rather positive, and he uploaded a short video demo showing Sports-a-Holic plugin playing a live NBA match, and a ESPN Boxing program. Whereas you had to pre-order and be patient for the first batch, LTBB is now available on Amazon for $129.99. Considering it also includes a dual sided RF remote control with a QWERTY keyboard, this single core set-top box is about the same price, or […]

Texas Instruments SensorTag Unboxing, Getting Started with Bluetooth Low Energy in Linux (with a Raspberry Pi)

Texas Instruments CC2541 SensorTag is a Bluetooth Low Energy (BLE) development kit with 6 sensors (IR temperature, humidity, pressure, accelerometer, gyroscope, magnetometer) mainly destined at mobile application developers for iOS, and soon, Android 4.3. I’m interested in BLE, as I expect most new phones with come with BT 4.0 BLE (aka Bluetooth SMART), and this technology may help bring the Internet of things to life, allowing us to interact with sensors, smart appliance (e.g. light switch)… Since it just costs $25 (including international shipping), I decided to buy it, and give it a try. Today, I’ll show some unboxing pictures, and how to communicate with the kit using the Linux command line. TI SensorTag Unboxing I ordered it at the end of May, and receive it by Fedex on the 18th of July, about 7 weeks later, in the package below. Inside we’ve got a Quick Start Guide for iOS […]

WigWag Simplifies Home Automation, Provides Raspberry Pi and Arduino Shields

WigWag is an home automation kit aiming at simplifying home automation, yet allowing developers to roll their own system via Arduino and Raspberry Pi Shields. Wigwag is currently composed of three devices: WigWag Sensor Block – Universal sensor device with 8 environmental sensors (light, detect motion, sound, temperature, humidity, movement…), 4 control features (relay, IR blaster…), and 2 expansion ports. It can be powered by 4x AA batteries (possibly for up to 1 year), or a USB power adapter. This device runs Contiki OS on Freescale MC1322 MCU (with built-in 6LoWPAN radio). WigWag Relay – Connects WigWag and third party devices to their cloud service, allowing interaction with Internet services, such as email, Dropbox and Twitter. It acts a bit like a central server managing all your WigWag Sensor Blocks or other connected devices such as Phillips Hue light bulbs or Belkin WeMo outlets in your house. IP networks (Wi-Fi & Ethernet) […]

DIY Stripboard/Veroboard Enclosure for Raspberry Pi (Part 2)

Rasbperry_Pi_Stripboard_LED_Relay

Following up my previous post entitled “DIY Modular Stripboard / Perfboard Casing for Raspberry Pi (Part 1)” where I explained how I created an modular enclosure made of perfboard, or the overall concept, I’ve now designed two “smart” sides for the enclosure: a 16-LED stripboard side, and a 5V relay stripboard side. Today, I’ll detail how I’ve done this, with details about electronics, soldering, assembly, the Linux distribution (built with Yocto), as well C programs, HTML page, and (CGI) shell scripts used to light up the 16 LEDs, and control a standard 220V lamp with a relay via my phone’s web browser. 16-LED Stripboard Top Schematics, Soldering, and Testing I had decided to design the top board of the enclosure with several LEDs, 3 LEDs on both side, and a Raspberry fruit (6 red LED) and 2 leaves (4 green LED) in the middle. Before getting started, I did some […]

A Preliminary XBMC Image is now Available for Wandboard, GK802

Yesterday, Stephan Rafin left a message on Wandboard mailing list saying he had released a preliminary (Linux) XBMC image that can run on Wandboard Quad development board. GPU and VPU acceleration work, but this is still work in progress, so if you want something that just works, this is not for you. But if you just want to give it a try, it should work on any hardware based on Freescale i.MX6, such as Wandboard Dual or GK802 mini PC, with some minor modifications. If you’ve got a Wandboard Quad board, the installation is straightforward from a Linux machine: Download the SD card image Decompress it with xz or 7x:

Dump the resulting to a 2GB or greater microSD card:

Where /dev/sdx is the sdcard device (e.g. /dev/sdc). You can check with lsblk command. If you’ve got a machine running Windows only, you can use Win32DiskImager for step […]
