Ugoos UG310 and UG320 Android STBs Based on Rockchip RK3188

In the last few months, there has been very little innovation or novelty in the Android set-top box and mini PC space, and the latest Ugood Android set-top boxes are yet other devices based on Rockchip RK3188 processor with 1 to 2GB RAM, and 8GB flash, as well as Wi-Fi and Ethernet connectivity, and a 5MP camera. They only differ from the competition because of their casings. Both devices mostly share the same specifications: SoC – Rockchip RK3188 quad core Cortex A9 @ 1.6Ghz with Mali-400MP4 GPU @ 500MHz? System Memory – 1GB DDR3 for UG320, 2GB DDR3 for UG310 Storage – 8GB flash + microSD card slot (Up to 32 GB) Video Output – HDMI and AV outputs Audio Output – HDMI, optical SPDIF, and AV (CVBS). Connectivity – Wi-Fi 802.11 b/g/n, and 10/100M Ethernet. Bluetooth 3.0 is available in UG320 only. USB: UG310 – 2x USB 2.0 host […]

Ninja Sphere Home Automation and Monitoring Platform

Ninja Blocks is an company providing open source hardware solutions for home automation. Their first product was called Ninja Blocks Kit which includes a Ninja Block (Beaglebone + Arduino based gateway, but they now also support the Raspberry Pi), sensors, sockets, cables, and a power supply, and works with Ninja Platform, an open source software framework. The goal was to simplify the process of developing automation applications by taking care of all low levels tasks such as electronics, embedded programming, network protocols.., and letting “end users” / developers focus on their application. The company is now working on a new version called the Ninja Sphere, including a “Spheramid” gateway, location waypoints (Bluetooth low energy tags), and smart power sockets. Here are the key features of the gateway: Processor – ARM Cortex A8 (probably Texas Instruments Sitara) Color LED Matrix Connectivity – Bluetooth, Bluetooth LE, Zigbee, and Wi-Fi USB Port – […]

SD Association Announces Ultra High Speed (UHS) Speed Class 3 for 4K2K Video Recording

SD card are not the fastest storage devices, but they are usually good enough for the job. One of the main use case is storage for video cameras, but with devices supporting 4K2K (2160p) recording they are close to their minimum limits. That’s why the SD association announced Ultra High Speed (UHS) Speed Class 3 (U3), which provides at least 30 MB/s write speed. The updated SD card speed classes are shown in the table below. Marks Operable Under Applications SD Memory Card Speed Class High Speed Bus I/F Full HD video recording HD still consecutive recording SD, miniSD, microSD SDHC, miniSDHC, microSDHC SDXC, microSDXC Normal Bus I/F HD ~ Full HD video recording SD video recording UHS Speed Class UHS-I Bus I/F UHS-II Bus I/F Full higher potential of recording real-time broadcasts and capturing large-size HD videos (UHS Speed Class1 denotes a 10 MB/s minimum write speed) SDHC […]

Google’s Portable Native Client Builds Architecture Independent Executable for Portability, and Better Performance

Native Client (NaCl) allows to build native C and C++, and runs it in the browser for maximum performance. Applications such as photo editing, audio mixing, 3D gaming and CAD modeling are already using it. The problem is that you have to build the code for different architecture such as ARM, MIPS or x86. To provide a portable binary, Google announced the Portable Native Client (PNaCl, pronounced pinnacle), which “lets developers compile their code once to run on any hardware platform and embed their PNaCl application in any website”. Instead of compiling C and C++ code directly to machine code, PNaCl generates a portable bitcode executable (pexe), which can be hosted on a web server. Chrome then loads this executable, and converts it into an architecture-specific machine executable (native executable – nexe) optimized for the device where the code runs. Bullet physics simulators (Shown below) and Lua interpreters are two […]

CS918S Android STB Features AllWinner A31s Processor, a Retractable Webcam, Built-in 3G

K-R42-1, now better known as CS918, has been a fairly popular Android set-top box based on RK3188 due to its low price. There’s no a new model called CS918S with a similar casing, but replacing Rockchip RK3188, by AllWinner A31s, adding more flash (16GB), a retractable webcam, and an internal bay with an optional 3G/4G module. Here are the specs of this device: SoC – AllWinner A31s quad cortex cortex A7 processor @ 1.2 GHz + PowerVR SGX544MP2 GPU System Memory – 2GB DDR3 Storage – 16GB NAND flash + microSD card slot Video Output – HDMI and CVBS (AV) Audio Output – HDMI, optical SPDIF, and AV Video Playback / Encoding 2160p (UHD) H.264 decoding 1080p video decoding for Mpeg1/2, Mpeg4 SP/ASP GMC, H.263, H.264, etc. 1080p@30fps or 720p@60fps encoding 3840×1080@30fps 3D decoding, BD/SBS/TAB/FP supported 3840×1080@30fps 3D encoding Connectivity – Wi-Fi 802.11 b/g/n, Bluetooth 4.0 (Realtek 8723), 10/100M Ethernet, […]

Linaro 13.10 Release with Linux Kernel 3.12 and Android 4.3

Linaro has just posted a blog entry to announced Linaro 13.10 was available for download. This is normally supposed to occur on the last Thursday of the month, but it’s possible the release occurred on scheduled, and the blog post was late, or it may have been delayed because of Linaro Connect US 2013. You can access a summary of the event together with slides and videos of the sessions and keynotes when available. This release includes the Linux Kernel 3.12-rc5 (staging), Kernel 3.10.14 (LSK), Android 4.3.1, and Ubuntu Linaro 13.10 (still based on Raring). Android has been ported and updated to 4.3.1 from AOSP, and the OS can now boot using UEFI. More work has been done on ARM 64-bit (aka ARMv8 or Aarch64) for Android, the Linux kernel, and tools such as uprobes, o-profile, and ftrace. Some new hardware platforms I may have missed before have popped up […]
