WeTek Hub and WeTek Play 2 TV Boxes Giveaway

I may just have finished Giveaway Week at the beginning of the month with my own review samples, but I have three new devices to offer courtesy of WeTek who asked me whether I could organize a giveaway for two WeTek Hub and one WeTek Play 2 Android & OpenELEC TV boxes on CNX Software. For some reasons I’ve been unlucky with my attempted reviews of the two devices with my WeTek Hub review sample having severe stability issues, while my country’s customs office required time-consuming and expensive paperwork for WeTek Play 2, so I had to abandon the package. End of the day, I did not review either. Other reviewers were luckier, with – from what I’ve seen – positive reviews for both devices. For example, Mark Hodgkinson concluded his review of WeTek Hub on AV Forums as follows: The Wetek Hub is a well-designed little device, both inside […]

R-Box Pro 3G Android TV Box Review – Part 2: Android 6.0 Firmware

The vast majority of octa-core Android TV Boxes sold on the market comes with 2GB RAM, but Amlogic S912 based R-Box Pro TV box was interesting with its 3GB RAM option (aka R-Box Pro 3G), as I wondered if I would see any noticeable improvements during my tests with the extra RAM. We’ve already confirmed the the hardware comes with 3GB RAM using 2x 1GB + 2x 512MB RAM chips configuration in the first part of the review last month, and it’s now time to check out whether this translates to anything in Android, as well as go through the usual hard-to-get features to work like automatic frame rate switching and HD audio pass-through. First Boot, Firmware Update, and First Impressions One positive with the device is the four USB ports, so this time I did not need an USB hub at all, and connected a USB HDD, two RF […]

Raspberry Pi 2 Gets an Upgrade to 64-Bit Broadcom BCM2837 Processor with PCB Version 1.2

With the launch of Raspberry Pi 3 based on Broadcom BCM2837 quad core Cortex A53 processor earlier this year, sales of Raspberry Pi 2 boards have suffering meaning the demand for Broadcom BCM2836 quad core Cortex A7 processor has also been reduced, and it appears the Raspberry Pi foundation has now launched Raspberry Pi 2 V1.2 with the faster BCM2837 processor. The new Raspberry Pi 2 v1.2 runs BCM2837 CPU cores up to 900 MHz, instead of 1.2 GHz on RPi 3, and includes 1 GB RAM. The main difference with Raspberry Pi 3 is the lack of the WiFi and Bluetooth module, which may also prevent some UART issues if you want to access the serial console or use an add-on board with UART. Since both boards cost the same ($35), most people should probably stick with Raspberry Pi 3, unless you’d rather not have any wireless module on […]

A Closer Look at Ingenu RPMA Alternative to LoRa or Sigfox LPWAN Standards & RPMA Development Kit

I’ve recently started to write a bit more about long range LPWAN standards for IoT applications, especially LoRa and Sigfox, as commercial networks are being launched, and relatively low cost hardware platforms are being introduced to the market. There are also other highly expected standards such as Weightless and LTE Cat M that will bring more competition to the market. Ingenu RPMA (Random Phase Multiple Access) is another available standard that’s been in deployment for a while, and based on an earlier comparison of  long range LPWAN standards, it comes with long range, supports up to 384,000 nodes per “sector”, operates in the unlicensed 2.4 GHz ISM band, and offers high combined uplink and downlink bandwidth than competitors. Ingenu recently contacted me and provided some more details and information about their technology and development kit. One of the documents includes an “independent analysis completed by ABI Research, Inc.” comparing features […]

How to Create a Bootable Recovery SD Card for Amlogic TV Boxes

I reviewed Rikomagic MK22 TV box about two weeks ago, and with the firmware I had, online firmware update was not enabled, and the company only released .IMG firmware for Amlogic USB Burning Tool, a windows-only tool that’s not well designed, and requires some procedure that vary slightly from boxes to boxes which in some cases forces to buy a male to male USB cable. I’ve now started reviewing R-Box Pro TV box also based on Amlogic S912 processor, online firmware update is not working either, and again I only managed to find .IMG firmware for the box on GeekBuying. However, I’ve been informed that “USB Burning Tool” firmware can now be flashed through a micro SD card, or USB flash drive with all recent Amlogic TV boxes, so I’ve tried this method instead of R-Box Pro, and decided to report my experience in this post following some instructions on […]

Vorke Z1 Amlogic S912 Android TV Box Comes with 3GB DDR4 Memory

DDR4 memory is coming to one more TV box. We first discovered it in Yundoo Y7 TV box powered by Amlogic S905X processor, but now Vorke, which started with Vorke V1 Intel Braswell mini PC and then V2 Ultra earlier this year, has now launched Vorke Z1 TV box with an octa-core Amlogic S912 processor combined with 3 GB DDR4 memory with higher bandwidth than your typical DDR3(L) memory. Vorke Z1 specifications: SoC – Amlogic S912 octo-core ARM Cortex A53 processor @ up to 1.5 GHz with ARM Mali-820MP3 GPU System Memory – 3GB DDR4 Storage – 32GB eMMC flash + micro SD slot up to 32GB Video Output – HDMI 2.0a with HDR and CEC support up to 4K @ 60 fps, and 3.5mm AV jack for composite output Audio Output – HDMI, AV jack (stereo audio), and optical S/PDIF Video codecs – VP9, 10-bit H.265 up to 4K […]

Getting Started with Sonoff TH16 ESP8266 Relay and Sensor using the Stock Firmware and eWelink Android App

Sonoff TH16 is a WiFi relay device powered by Espressif ESP8266 WiSoC, able to handle a load up to 16A (3500Watts @ 220V), and including a jack for sensors. The company recently sent me a sample together with  Sonoff AM2301 temperature and humidity sensor, and Sonoff POW power meter device, and in the first part of my Sonoff review I checked out the hardware for all three items. In the second part, I’ll report my experience with Sonoff TH16 and the temperature sensor with a practical example, as I’ve installed it to control a groundwater pump. What you see above is a picture of my house water tank with two pumps, the white one keep the pressure in the taps and is always on, and the blue one pumps the water from the ground and is the one I’m going to control. Over the last year or so, I’ve tried […]
