YokaTV KB2 Review – Amlogic S912 TV Box with 32 GB Flash

CNXSoft: This is another review by Karl about Amlogic S912 based YokaTV KB2 TV box. Introduction Today we will be looking at Videostrong YokaTV KB2. Below are the specs from Videostrong website. This is my first S912 device so I had high expectation. I have been using it for quite some time now with no major issues. I received approximately 6 OTA updates since I started testing and some welcome updates have come. Build When I receive a box first thing I do is take it apart and check out the inside. I was excited when I found out it had 32 gig of storage. It is not too common. Then when I opened the box I was really happy to see an antenna that wasn’t soldered on. Makes it easy to add a different one. +1 for KB2. Then I noticed the heat sink. It seemed a little small. […]

Eweat R9 Plus Android TV Box and OpenWrt NAS Review – Part 1: Unboxing and Teardown

Zidoo X9S is getting some competition with Eweat R9 TV boxes based on the same Realtek RTD1295 processor with built-in SATA, Gigabit Ethernet, 4K VP9 and H.265, HDR, and USB 3.0. The company has three R9 models, and they sent me to top of the line R9 Plus with 2GB RAM, 16GB storage, a 3.5″ SATA bay, HDMI input, and dual Gigabit Ethernet ports for evaluation. I’ll start the first part of the review by checking out the hardware inside and out, before testing the firmware in the second part. Eweat R9 Plus Unboxing The device ships in a large package with a handle which can be convenient in brick and mortar shops since the whole package weights about 1.8 kilograms.The package then contains a smaller package will all accessories: a 12V/2.5A power supply, a “Quickly User Guide” (sic.), a HDMI cable, and an IR remote control taking two AAA […]

How to Use Sonoff POW ESP8266 WiFi Power Switch with MQTT and ThingSpeak

ITEAD Studio’s Sonoff is a family of cheap home automation products based on ESP8266 WiSoC, and I’ve already tested Sonoff TH16 wireless switch with a humidity and temperature sensor using the stock firmware and eWelink app for Android or iOS. It works, but up to recently it required a registration to a cloud service (the company will now allow use from the local network), and the source code is closed. So for the second device under review, namely Sonoff POW wireless switch with a power consumption monitor, I decided to install ESPurna firmware working on ESP8266 Sonoff devices and NodeMCU, as it’s open source, supports Sonoff POW natively, includes a web interface to control the device from the LAN, and includes an MQTT client. MQTT (Message Queuing Telemetry Transport) is a lightweight publish/subscribe messaging protocol used to control IoT sensors and devices, and it’s a popular method to gather data […]

How to Install ThingSpeak in Ubuntu 16.04

Last week-end I installed ESPurna open source firmware with MQTT server on Sonoff POW WiFi switch, and the next step is find a way to draw power consumption charts in some web based interface. We could do this in the IoT cloud with services like Xively or ThingSpeak, but since one of the goals of replacing the default firmware was not to rely on a proprietary cloud based solution, I decided to find a way to draw those chart in a local server, and it so happens that ThingSpeak is also open source with the code available on Github. Hardware platforms like NanoPi NEO / NEO Air, or Orange Pi Zero boards appear to be particularly well suited for the task of running an MQTT broker and Thingspeak, but at first I wanted to install ThingSpeak in my own Ubuntu 16.04 computer to have a try. As you can see […]

First Intel Apollo Lake J3455/J4205 Processor Benchmarks & Video Tests

Many products powered by Intel Apollo Lake processors have already been announced, but few are actually shipping, and I have yet to get one here. However, AndroidPC.es got hold of ASRock J4205-ITX and J3455-ITX motherboards powered by respectively a Pentium J4205 quad core processor and a Celeron J3455 quad core processor, run a few benchmarks, and tested videos in Windows 10 on the motherboards with Kodi 17 and MPC-HC. Let’s have a look at some of the benchmarks to better understand of what we can expect from Apollo Lake desktop processors. First there’s not that much of a difference between Celeron J3455 (1,771 points) and Pentium 4205 (1,830 points) in PCMark Home Convetional benchmark, however you should clearly feel a boost in performance compared to systems with Intel Cherry Trail x5-Z8300 processor (1,141), and the score is getting fairly close to a mini PC with an Intel Core i3-5005U […]

How to Build and Flash ESPurna Open Source Firmware to Sonoff POW Wireless Switch

ITEAD Studio Sonoff family is comprised of various inexpensive ESP8266 WiFi power switch, and the company sent me two of their latest CE certified models with Sonoff TH16 + external temperature & humidity probe, and Sonoff POW to measure power consumption. I checked the hardware is the first part of the review, and used Sonoff TH16 to control a water pump with the stock firmware and Ewelink Android app in the second part. It works reasonably well, but it relies on the cloud, so if you lose your Internet connection or the service closed, you can’t control the relay manually anymore. Luckily, the UART pins are exposed on Sonoff switches so you can solder a 4-pin header and connect a USB to TTL to flash your own firmware. Please don’t connect Sonoff devices to the mains when programming them, it’s very dangerous, instead the USB to TTL board will power […]

Getting Started with Pine64 PADI IoT Stamp – Part 2: Serial Console, GCC SDK, Flashing & Debugging Code

PADI IoT Stamp module powered by Realtek RTL8710AF ARM Cortex M3 WiFi SoC is a potential competitor to Espressif ESP8266 modules. Pine64, the manufacturer of the module, sent me their kit with a $2 IoT stamp, a breakout board, a USB to TTL debug board and a J-Link debug board. In the first part of the review I’ve shown the hardware and how to assemble PADI IoT stamp kit. In the second part I’m going to write a tutorial / getting start guide showing how to control the board with AT commands, build the firmware with GCC SDK, and finally demonstrate how to flash and debug the firmware with the J-Link debugger. The Quick Start Guide indicates you need to connect the USB to TTL debug board to UART2 instead of UART1 as I did on the very similar B&T RTL-00 RTL8710AF module, and set connection settings to 38400 8N1. […]

Adding Plus Sign and Tag to Email Address May Help Identify Source of (Spam/Junk) Emails

I’ve noticed several commenters using email formatted as [email protected] or [email protected] while posting comments on CNX Software blog, but I just thought they were using some specific emails account or some forwarding techniques to receive emails, but I did not investigate further, and by chance I came across the reason on reddit this morning: It’s just another character that can be in an email address. For example, [email protected], [email protected], [email protected], and [email protected] are all completely different email addresses. However, Gmail will ignore a + and everything after it in the username portion of an email address, so [email protected], [email protected], and [email protected] will all go to [email protected]‘s inbox. This is acceptable because Google does not allow + in its login names. Many people use this property to identify the source of an email. So I could not resist trying by sending myself an email by adding +source1 to my username, and […]
