ESP8266 Wi-Fi Module is Now Supported in Arduino IDE

ESP8266 revolutionized the IoT world by offering an ultra low cost Wi-Fi solution either standalone or connected to a micro-controller board via SPI or UART. There are plenty of tutorials on the web to play with the Wi-Fi module, but it’s only recently an Arduino IDE has added support for ESP8266. If you want to try it, you can download the binary for Linux, Windows, or Mac OS X. Since my computer is running Ubuntu 14.04, I download and extracted arduino-1.6.1-linux64.tar.xz to install it in my PC. Now simply run the arduino script to start the IDE, and select to Tools->Board->Generic ESP8266 board. I don’t own an ESP8266 module myself, but Olimex tried it on their ESP8266-EVB: They connected a serial debug board and selected Tools->Port->/dev/ttyUSB0 in the IDE Selected Tools-> Programmer->esptool Loaded Blink example, and modified it to turn on and off the relay on their evaluation board.

Kodi 14.2 Final and Kodi 15 Alpha 2 Released

Kodi developers have recently announced two release for Kodi: the stable version of Kodi 14.2 Helix, which should be the last Kodi 14 release, and Kodi 15 Alpha 2 Isengard with some interesting new features. Since Kodi 14.2 is a minor release, no new features have been added, but they fixed several bugs: Application stopped responding on Windows Gap-less playback on MP3 Playback of rtmp protocol Scanning of newly added episodes Fix multipath source scanning Loading external subtitles in some cases packaging of PIL module on Android. This fixes some script error when using weather add-on Fix video playback on all platform after refresh rate change Various bugs that were present in PVR add-ons. Save weather location Fix filtering of foreign add-ons ftps handling Use LastWrite instead of ChangeTime for file system on Windows As usual, you can download the release via Kodi download page for Windows, Linux.

Mr.NUC V3-J1900 is an Intel NUC Clone Based on Celeron J1900 Processor

Intel NUC (Next of Computing) are tiny and relatively low cost computers made by Intel. But in case you wondered if there were any clones available to save a few extra dollars, and/or gain a faster processor, a Chinese company is now selling Mr.NUC V3-J1900 barebone system with an Intel Celeron J1900 quad core processor for $169 + shipping, which adds over $40 since the mini PC only ships by courier. If you happen to live in the US, it’s probably not such as good deal, but in other countries maybe… This mini PC is said to be based on a custom designed motherboard made by Gigabyte (MZBAYAP) for Realan, with the following technical specifications: SoC – Intel Celeron J1900 Quad core processor  @ 2.0 GHz (base) / 2.41 GHz (Burst) with Intel Gen 7 HD graphics (10W TDP) System Memory –  DDR3L 1333/1666 MHz SO-DIMM slot Storage – 2.5″ […]

MeLE F10 Lite is an Air Mouse with Keyboard using 2x AAA Batteries

MeLE has several models of air mouse, and they are great to use with Android mini PCs, and sometimes I also use these with my regular PC. I started with the original MeLE F10, but then switched to MeLE F10 Deluxe which provides a better pointer control. It’s not perfect as game mode only works with MeLE media devices, I could never make the IR learning function work, and the pointer tends to jump when I press the OK button, so I’m using the mouse button for clicks instead as it does not suffer from this issue. Nevertheless, MeLE F10 Deluxe is still the device I prefer to use during my mini PCs and boards’ reviews. Previous MeLE F10 air mice all comes with a built-in battery, but some people prefer to use standard batteries, and that’s just what the latest MeLE F10 Lite uses, with other features similar to […]

Intel Provides Details for Atom x3, x5 and x7 Processors

Intel had already announced their plan to change Intel Atom branding to use x3/x5/x7 nomenclature in order to make it easier for consumers to navigate their product offerings, but the company has now provided much more details during their press conference at Mobile World Congress 2015. Intel Atom x3 (previously known as SoFIA) will be entry and ultra-low cost processor up with 3G or LTE connectivity found in products up to around $150, while Atom x5 and x7 (previously known as Cherry Trail) will be found in tablets between about $200 to $400, with the top performing devices going with Intel Core M processors. Intel Atom x3 are very interesting because they mix Intel 64-bit cores with ARM GPUs (to keep the cost down), and parts with RK suffix are made by Rockchip. Three x3 processors are currently available: Intel Atom x3-C3130 – Dual-core processor up to 1.0 GHz with […]

Vidonn X6 Activity Tracker Promises Up to 15 days Battery Life

I reviewed Vidonn X5 fitness tracker last yet, and I found many issues or letdowns: battery life is too short (2 days), the digits are much smaller than advertized, the screen cannot be read under direct sunlight, a button must be pressed to check the time, the smartband is not as waterproof as advertized, and the Android app is a disaster. Despite all these issues, I still wear it everyday, as it helps me walk or run a bit more if I have not reached my daily target. The company has now release a new model Vidoon X6 that I discovered today on DealExtreme for $33.90. Vidonn X6 specifications: MCU/Memory – Unknown Display – 0.88″ OLED display (vs 0.49″ for X5) Connectivity –  Bluetooth 4.0 LE and micro USB Battery – 45 mAh Li-battery (vs 40 mAh) good for 15 days in standby mode. IP Rating – IP65 (Dust-proof and […]

Raspberry Pi 2 / ODROID C1+ Development Boards Comparison

Raspberry Pi 2 Model B board has just been released, and although it’s not a direct answer to ODROID-C1, as Broadcom started the design for BCM2836 SoC for RPI2 a long time ago, both low cost development boards have similar specifications, with a quad core processor, 1GB RAM, Ethernet, and four USB ports, as well as the exact same price: $35. So I’ve decided to compare both in details to find out the actual differences, and which one may be more suitable to a particular application. Let’s get straight to the comparison table. [Updated on November 24 to use ODROID C1+ instead of ODROID C1] Hardkernel ODROID C1+ Raspberry Pi 2 Model B Comment Processor Amlogic S805 quad core Cortex A5 @ 1.5 GHz (Overclockable to 1.7 GHz or more) Broadcom BCM2836 quad core Cortex A7 @ 900 MHz (Overclockable to 1.1GHz or more) Despite the architecture advantage for Cortex […]

X29 Intel Celeron J1800 / J1900 mini PC Sells for $125 and Up

Today, somebody asked me to test 4K output on Intel Atom Z3735F, but I can’t do that since the platform only supports 1080p. As I just posted my unboxing of MeLE PCG03 mini PC, I noticed several ICs where added for extra functionalities, and people also started to complain about lack of Gigabit Ethernet, Fast Ethernet via a USB bridge, no USB 3.0, and no SATA. That’s what happens when you use a Tablet SoC in a mini PC, but if you’re ready to pay a little more, you could still get a mini PC with a proper desktop processor (Bay Trail-D) including SATA, USB 3.0, and Gigabit Ethernet (maybe) for about $125 (shipped) with X29-J1800 computer powered by Intel Celeron J1800 (10W TDP). That’s the price for the barebone system without RAM or storage, and if you want a complete system with 32GB eMMC and 4GB RAM the price […]
