V-Bridge Muses DTV Modulator and Video Encoder Review – Part 2: Muses-β Turnkey Solution Demo

V-Bridge Muses-α and Muses-β boards can be used to respectively broadcast video to DTV standard from your PC, and as a turnkey solution taking any HDMI, CVBS, or USB inputs. The VATek SoC used in those  board support various DTV standards including DVB-T, DVB-C, ATSC/QAM, DTMB, ISDB-T/TB up to full HD resolution. I’ve received an early prototype for each, and I’ve already taken pictures and show how to assemble both Muses-α and Muses-β kits in the first part of the review. Today, I’ll show a demo with Muses-β turnkey solution taking HDMI input from an Android TV box (R-Box Pro), encoding and modulating the video to DVB-T, before broadcast it to an Android STB with a DVB-T/T2 tuner (U4 Quad Hybrid). This tool could be useful to test STB featuring ATSC or ISDB-T too, as those two standards are not supported in my country, and I could instead generate signals […]

Rikomagic MK22 Review – Part 2: Android Firmware, Video & Audio in Kodi, Benchmarks…

Rikomagic MK22 is one of the many Android TV boxes powered by Amlogic S912 octa-core processor with typical hardware specifications such as 2GB RAM, 16GB flash, Gigabit Ethernet and dual band WiFi. I’ve already taken the box apart to check out the hardware in the first part of the review, so I’ll focus on the firmware, but I’ll keep it short focusing on typical problem areas, as I’ve already reviewed a bunch of other Amlogic S912 TV boxes such as Qintaix Q912 or Beelink GT1. First Boot, Firmware Update, and First Impressions After having connected all usual cables and  accessories include a 1TB USB hard drive, and RF dongles for my air mouse and wireless gamepad, I booted the device, and after around 45 seconds (typically), I got to the main launcher. Since I received the device about a month ago, I decided to go to the UPDATE&BACKUP app to […]

Amlogic USB Burning Tool Still Sucks in 2016

[Update November 2016: If you don’t like USB Burning Tool or don’t have the necessary USB cable, you can flash Amlogic IMG firmware to a micro SD card instead] In the first few years when Android TV Boxes/mini PCs started to hit the markets, in the 2012-2014 period, online firmware update was inexistent for the vast majority of the boxes, and if you wanted to update your firmware you had to use some windows tools like USB Burning Tool for Amlogic, AndroidTool for Rockchip, or PhoenixUSBPro / PhonixSuite for Allwinner platforms. All those tools have poor design, for example the window is not resizable, so it’s impossible to your an old netbook (1024×600 resolution), and then you have to install drivers which is easy, for after detection of the box may be hit and miss, and you have to follow a procedure with the right power sequence with a USB […]

Sonoff POW and Sonoff TH16 WiFi Relays Review – Part 1: The Hardware

Sonoff TH16 is a WiFi 16A relay that can take external sensors via a 2.5mm jack, while Sonoff Pow is a WiFi relay capable of measuring power consumption. Both have been designed by ITEAD Studio, and feature Espressif ESP8266 WiSoC. The company sent me both items for review, and I’ll start by checking out the hardware a little more closely than what is possible during the product announcement. I received Sonoff TH16 together with Sonoff AM2301 temperature and humidity sensor, which I’ll use to use to control an outdoor water pump and gather temperature and humidity data, as well as two Sonoff POW relays,which I plan to use to measure power consumption in my office, both from the power outlets and my aircon. All three WiFi relays support 3500 Watts, and 85 to 250V input. The packages have three QR codes for eWeLink iOS app, the Android app (coolkit.apk), and […]

ONENUTS Nut 1 TV Box Specifications, Unbagging and Teardown

I first discovered Shenzhen Tomato’s ONENUTS brand through ONENUTS T1 3-in-1 projector, tablet, and mini PC, but the company has now launched a new product with ONENUTS Nut 1 Android TV box powered by Amlogic S912 processor, and the usual 2GB RAM and 16GB storage, but the product stands out a little thanks to its presentation as we’ll see below. ONENUTS Nut 1 Specifications The technical specifications are pretty much standard: SoC – Amlogic S912 octa-core ARM Cortex A53 processor @ up to 1.5 GHz with ARM Mali-820MP3 @ up to 750MHz System Memory – 2GB DDR3 Storage – 16GB eMMC flash + micro SD slot up to 32GB Video Output – HDMI 2.0a up to 4K @ 60Hz with CEC and HDR support, and AV port (composite) Audio Output – HDMI, AV (stereo audio), and optical S/PDIF Connectivity – Gigabit Ethernet, dual band WiFi 802.11 b/g/n/ac, Bluetooth 4.0 USB […]

Getting Started with RabbitMax Flex IoT and Automation Hat for Raspberry Pi

At the beginning of the month I showed how to assemble RabbitMax Flex, a Raspberry Pi HAT compliant add-on board for Raspberry Pi boards with 40-pin header, that targets IoT and home automation project with its relay, IR transmitter and receiver, I2C headers for sensors, buzzer, RGB LED, and more.  Since I’ve already described the hardware, I’ve spend some time this week-end following the user’s guide to play around with the board using a Raspberry Pi 2 board, and try various features. The user’s manual explains that you need the latest version of Raspbian, but I’d not played with my Raspberry Pi 2 board for a while, so the kernel and firmware were quite old:

So the first thing I had to do was to upgrade Raspbian. There are basically two options to upgrade, either downloading and dumping the latest Raspbian firmware image to your micro SD card, and […]

Realtek RTL8710AF (PADI IoT Stamp) vs Espressif ESP8266 (ESP-07) WiFi RF Performance Comparison

After I posted about PADI IoT Stamp IoT kit based on RTL8710AF ARM Cortex M3 WiSoC yesterday, I was soon asked whether I could compare the RF performance against ESP8266 modules like ESP-12. I don’t have any equipment to do this kind of test, except for some simple test like testing range with WiFi Analyzer app, but I remember Pine64 told me they had some comparison data a little while, and accepted to share their results. The test setup is comprised of Litepint IQ2010 multi-communication connectivity test system and PC software, as well as the device under test (DUT) with PADI IoT Stamp (version with u.FL antenna connector) and ESP-07 ESP8266 module as a u.FL connector is required to connect the test system. They’ve tested 802.11b, 802.11g, and 802.11n, but for IoT projects 802.11b is the most important as usually long range is more important than data rate. Test results […]

Pine64 PADI IoT Stamp WiFi IoT Kit Review – Part 1: Hardware, Debuggers, and Soldering

Back in September, Pine64 unveiled their $2 PADI IoT Stamp based on Realtek RTL8710 ARM Cortex M3 WiFi SoC aiming to compete with Expressif ESP8266 solutions.  The company has now sent me their complete kit for review, which beside the module itself includes a breakout board kit, and some hardware debug tools. In the first part of the review, I’ll check out the hardware, and solder the kit. I received a package with four antistatic bags. From top left to bottom right, we have PADI IoT Stamp, JLINK-OB debugger based on an STM32 MCU with some jumper wires (aka Dupont cables) for SWD signals, and a USB cable to your computer in order to flash the firmware or do some bare metal programming, a breakout board kit including two headers, a RED LED, and a resistor, and finally a USB to Serial board based on CH340G with 4 jumper wires […]
