Bodhi Linux Distribution Has Dropped Official ARM Support (For a While)

Linux is omnipresent in your life via gadget running Android, but in the desktop world, as many of you already know, it’s not straightforward to get a Linux distribution fully work on ARM platform, because each ARM SoC or board is different, and above all binary blobs used for GPUs, VPUs, Wi-Fi and Bluetooth chips can make it extremely complex, even impossible, to have a fully working ARM Linux distribution for a given hardware. After considering that ARM Linux required too much effort, and was not used by many people, Bodhi Linux developers decided to call it a day in October this year, and dropped official support for ARM hard-float images: Effective immediately Bodhi is dropping official support for ARM devices. What does this mean? We will no longer be advertising an ARMHF download link on our front page Updates to ARM images will be infrequent/not at all. The ARM […]

$5.40 CHARGER Doctor Makes USB Power Measurements Easy

One way to make power measurement for USB powered devices is to make your own USB cable to allow for current measurement via a multimeter, but if you think it’s just too much hassle, I’ve found and purchased a small test device called CHARGER Doctor that shows voltage and current on a 4 digit display, and sells for $5.40 on DealExtreme. The device features a USB female out port, and a USB male input port, that you can place between your USB power adapter, and the cable to your device to alternatively display voltage (4 seconds) and current (9 seconds). It can be used for power consumption measurements, to test if your charger is working normally, or finding out the power adapter that will charge your phone the fastest. It’s said to support measurement between 3.5 to 7V and 0 to 3 A, with an accuracy of +/- 1%. I’ve […]

Rezence Wireless Charging Standard Gets Rid off Charging Pads, Leverages Bluetooth 4.0 LE

I’ve just found out via my twitter feed that Nordic Semiconductor had announced the availability of the Bluetooth LE-based S120 8-link central protocol stack and nRF51 Wireless Charging SDK for wireless charging applications based on a new wireless charging standard called Rezence. The Alliance for Wireless Power (A4WP) gave their wireless power technology the name Rezence a couple of weeks ago. Rezence uses magnetic resonance, instead of inductance used in first generation products, and bring several key improvements: Greater charging range – Your device does not need to be placed on a charging pad, but it can be placed anywhere within range (I could not find data yet). Multiple device charging – Ability to charge multiple devices with different power requirements at the same time, such as smartphones, tablets, laptops and Bluetooth headsets. Up to 8 devices with Nordic Semi solutions mentioned in the introduction. Ready for the real world […]

WiDicast EC-E2 Wi-Fi Display (EZCast / Miracast / DLNA) HDMI Dongle Review

After my review of Tronmart T1000, an EZCast / Miracast / DLNA HDMI adapter, I’ve received another EZCast dongle with the same features called WiDiCast EC-E2 sent to me by Shenzhen EC Technology, the manufacturer of the device. In case you are not familiar with this type of device, they allow you mirror and control your smartphone / tablet (Android, iPhone, iPad) or computer (Windows, Mac OS X) display on an HDMI TV. Today, I’ll go through the specifications, show some pictures including a comparison with T1000, and try it with an Android smartphone. WiDicast EC-E2 Specifications Like all other EZCast adapters,WiDicast is based on Actions Semi SoC: SoC- Action Semi AM8251 @ 600MHz (MIPS) System memory – 128 MB DDR3 RAM Storage – 128 MB NAND Flash Video output – HDMI Wi-Fi – 802.11 b/g/n Wi-Fi Standards – Miracast, Airplay, DLNA, and EZCast Video container formats – avi, .divx, […]

Mini Review of Jynxbox Live, a $350 Android Live TV Streaming Box

A few days ago I showed some unboxing pictures and videos for Jynxbox Android M6 and Jynxbox Live, followed by Jynxbox Android M6 review, and today I’ll quickly review Jynxbox Live, an Android TV Box that based on Rockchip RK3066 (full specs available in unboxing post) that can stream over 200 live TV channels after install a Live TV app / crack, and happens to cost a “mere” $350 allegedly because it give access to these live TV channels. From the outside, Jynxbox Live looks very much like any other Android TV box, with HDMI, Ethernet, S/PDIF, three USB ports, a micro SD slot, a few LEDs, and a Wi-Fi antenna. To get started I’ve connected the provided HDMI cable to the box and my TV, as well as an Ethernet cable, before powering up the device with the USB power supply. After a few seconds wait, you’ll get the […]

Android 4.4.2 KitKat Beta Released for Rockchip RK3188 mini PCs

I’ve just been informed that Android KitKat, version 4.4.2, is now available for Rockchip RK3188 powered mini PCs based on AP6210 Wi-Fi module. This is a beta version, but it’s known to work for MK908 II, CX-919, GM282, GK525, iMito QX2, and IPPLI Mars I2C HDMI TV dongles. Albeit MK908 is also based on AP6210 Wi-Fi module, it does not appear to work right now, and the “new” model of MK802 IV with AP6210 might work, but has not been tested. Devices based on AP6330 and other Wi-Fi modules, such as T428 mini PC, are not working with this firmware, and you’ll have to wait a few more days or weeks to get a compatible firmware. Android 4.4 will bring new features that can be interesting with mini PCs such as printing support, screen recording, and overall better graphics and streaming performance. So with the recent release of AndrOpen Office, […]

Crowdfunding Report 2013 on CNXSoft Blog

Crowdfunding has really took off in 2013, with sites like Kickstarter and Indiegogo, as they enable start-ups to launch new and innovative products, and some established, even large companies, I’m thinking Canonical with Ubuntu Edge here, have also tapped into that market, actually shifting part of the risks from shareholders, to customers / individual funders. In this post, I’ll go through all the crowdfunding projects, 16 Indiegogo and 25 Kickstarter campaigns, featured on cnx-software.com between the beginning of December 2012 till the end of November 2013, to find out which ones have been a stellar success in terms of funding and on-time delivery, and those that have failed in one way or another, with some being close to looking like scams. There was a wide range of products with dealing home automation, the Internet of things, wireless Arduino compatible boards, Linux development boards, media players and more. Let’s go straight […]
