WordPress Mobile Caching with Zencache PRO Cache Plugin

March 28th, 2015 3 comments

This post has nothing to do with embedded systems, but I’ll document some of the changes I made to the website in the last few days for better mobile support. Recently Google sent me a message recommending to “Fix mobile usability issues found on http://www.cnx-software.com” via Webmaster Tools, and a user recently complained about readability from his smartphone.  So I had to fix this issue. This involves WordPress cache plugins and WPtouch Mobile Plugin, the latter automatically generates a mobile version of the website as shown on the right in the screenshot above. In theory, it’s very easy, you simply install WPtouch Mobile plugin, and mobile user agents get served the mobile page while other get the desktop version. But when you mix it with a cache plugin, it can become more complicated, and desktop user may be served mobile pages, and mobile user may get desktop pages. The easiest way to work around this is have a list of…

Howchip is Teasing ExSOM-7420SB Development Board Based on Samsung Exynos 7420 Processor

March 27th, 2015 No comments

We’ve already seen a few Cortex A53 boards announced in the last few months with Nobel64, as well as Hikey & DragonBoard 410c 96Boards, but none of them are based on the more powerful Cortex A57 cores. Howchip is going to change that with the upcoming ExSOM-7420SB single board computer featuring Samsung Exynos 7420 processor used in Galaxy S6 smartphone. The company has released very few details about the board, except the block diagram above that shows Exynos 7420 with 3GB LPDDR4 PoP memory, and various interfaces such as USB 2.0/3.0, UFS/eMMC, Ethernet, HDMI, MIPI DSI, Camera, as well as Wi-Fi and Bluetooth connectivity. The board will support Android 5.0 Lollipop 64-bit. No word about Linux. That’s the video teaser, but you won’t learn much… More details should eventually be published on ExSOM-7420SB product page. Alternatively, Hardkernel will also probably launch an ODROID-XU4? board based on the latest Exynos 7 processor in due time. We’ve already seen a few Cortex…

PiJuice Battery HAT Module for the Raspberry Pi Boards Comes with an Optional Solar Panel (Crowdfunding)

March 27th, 2015 2 comments

The Raspberry Pi is a low power board that can be powered a few hours or a few days with batteries, and the easiest solution is probably to use a USB power bank connected to the micro USB port of the board, but the solution is not really integrated. That’s where PiJuice comes into play. It’s a HAT compatible module that connects nicely to the latest Raspberry Pi boards with 40-pin header (A+, B+ and B2), and include a 1,400 mAh battery that can be used as UPS (Uninterrupted Power Supply), an RTC, and more. Key features of PiJuice HAT: 1400 mAh  Lipo battery, good enough to last up to 24 hrs in constant use. 5,000 mAh batteries are also said to be supported. Full UPS (Uninterrupted Power Supply) solution Integrated RTC (Real Time Clock) On board intelligent on/off switch Low power deep-sleep state with wake on interrupt/calendar event On board intelligent micro-controller (MCU) with custom firmware Programmable multi-colored RGB…

PiPO X7s mini PC Dual Boots Windows 8.1 and Android 4.4 for $130

March 27th, 2015 4 comments

Pipo X7 Bay Trail-T mini PC was very popular at the beginning at it sold with an apparently valid Windows 8.1 license for $90, even including one-year subscription for Office 365, which normally sells for $99. Unfortunately, it turned out the Windows license was not so valid, as Pipo used the free Windows 8.1 with Bing for tablets, something that Microsoft did not allow, and mini PCs instead need to use another $25 to $30 license (Windows 8.1 with Bing NTE), which brought Pipo X7 price to around $120, closer to its main competitors. There’s now Pipo X7s, another version based on the same hardware, that can boot both Windows 8.1 (with proper license) and Android 4.4, and can be pre-ordered on GeekBuying for $129.99. The hardware specifications appear to be identical to the Windows only version: SoC – Intel Atom Bay Trail Z3736F @ 1.33 GHz (Burst Freq: 2.16 GHz) with Intel HD graphics. System Memory – 2GB DDR3L Storage…
