Flagship mobile devices often come with wireless charging capability, but there’s an easy way to add (Qi) wireless charging to almost any smartphone, or possibly tablet, thanks to wireless charging receivers that simply connect to the micro USB port of your mobile device, and can be purchased for as low as $7 on Aliexpress, Ebay, DX.com, etc… I’ve also seen Adafruit made a Qi Wireless Receiver module for Arduino with a 2.54mm pitch connector. They come in various sizes and shapes, but they’re all extra thin (1 mm), with a micro USB connector oriented upwards or downwards depending on your mode, and a thin cable, that allows you to place it inside your phone between the battery and the phone cover as shown in the picture below. It’s not always possible however, as for example the receiver would cover my phone’s rear camera lens, but you could always attach it […]
Vsmart V52D EZCast HDMI Dongle Supports Dual Band (2.4 / 5.0GHz) Wi-Fi
EZCast wireless adapters are now pretty common, allow you to display and stream documents, pictures, music, and videos from your smartphone or computer to your big screen TV, and sell for about $20, but the vast majority come with a 2.4 GHz Wi-Fi module, which may be a problem if your environment is crowded with other 2.4GHz routers. Vsmart V52D fixes that, as it includes a dual band Wi-Fi module supporting both 2.4 and 5.0 GHz frequencies. The other part of the specifications remain the same: SoC – Action Semi AM8251 @ 600MHz (MIPS) System memory – 128 MB DDR3 RAM Storage – 128 MB NAND Flash Video output – HDMI 1.3 make Wi-Fi – Dual band 802.11 b/g/n Wi-Fi module Standards – Miracast (EZMirror), Airplay (EZ Air), DLNA, and EZCast Video Containers – MPEG2, MPEG4, AVI, WMV, MKV, MOV, RM, RMVB Audio Formats – MP3, WMA, WAV, OGG, AAC, […]
Applied Micro X-Gene (64-bit ARM) vs Intel Xeon (64-bit x86) Performance and Power Usage
A group of researcher at CERN have evaluated Applied Micro X-Gene 1 64-bit ARM XC-1 development board against Intel Xeon E5-2650 and Xeon Phi SE10/7120 systems, and one of them, David Abdurachmanov, presented their findings at ACAT’ 14 conference (Advanced Computing and Analysis Techniques) by listing some of the issues they had to port their software to 64-bit ARM, and performance efficiency of the three systems for data processing of High Energy Physics (HEP) experiments like those at the Large Hadron Collider (LHC), where performance-per-watt is important, as computing systems may scale to several hundred thousands cores. Intel Xeon Phi platform based on Many Integrated Cores (MIC) computer architecture was launched the HPC market, and contrary to the table above features 61 physical cores. Applied X-Gene 1 (40nm process) was used instead of X-Gene 2 built on 28-nm process which was not available at the time. The ARM platform ran […]

Beyond Semi Introduces 32-bit BA20 Core with Cortex M4 Performance Efficiency, and Cortex M0+ Silicon Area
Beyond Semiconductor and CAST have jointly announced BA20 32-bit embedded processor core with PipelineZero Architecture (zero-stage execution pipeline), that rivals with ARM Cortex A4 in terms of performance per MHz, while using about the same silicon area as an ARM Cortex M0+. which could be critical for applications such as wearables, sensors, and wireless communication, that may require both a small footprint and high performance efficiency. The company’s PipelineZero micro-archirtecture can execute one instruction per cycle, hence saving energy by doing more in less time, and by operating at lower clock rates. Key features listed for BA20 IP core: PipelineZero architecture for high performance efficiency with tiny silicon footprint 3.04 DMIPs/MHz (vs ARM Cortex M4: 1.25 DMIPS/MHz) 3.41 Coremarks/MHz (vs ARM Cortex M4: 3.40 CoreMarks/MHz) 2µW/MHz (vs ARM Cortex M0+: 3µW/MHz) 10K gates (0.01mm2) in 9-track 40G (vs 0.009mm2 for ARM Cortex M0+) BA2 ISA Extreme Code Density for less […]
Radxa Rock Pro / Lite Development Boards are Now Open Source Hardware
Many projects claim to be “open source hardware” (OSHW) after they’ve released the schematics in PDF format, and source code. But the definition of OSHW has a few more requirements, which is practise means you’ve got to release schematics and PCB layout in the native format, not only in PDF, as well as the gerber files, and the bills of materials. Open Source Hardware can also truly be useful, if you can source the components. and for example, Broadcom BCM2835 processor might be impossible to procure, especially in small quantities, and that makes the Raspberry Pi unsuitable as an open source hardware platform. Existing companies / associations dedicated to OSHW include Arduino, Beagleboard.org, Olimex, etc.., and today Radxa has joined the club by releasing all hardware designs files for Rockchip RK3188 based Radxa Rock Pro and Lite development boards (2014 version) under a Creative Commons Attribution 4.0 International License.
