Linux 4.9 Release – Main Changes, ARM and MIPS Architectures
Linus Torvalds released Linux 4.9 on Sunday: So Linux 4.9 is out, and the merge window for 4.10 is thus open. With the extra week for 4.9, the timing for the merge window is obviously a bit awkward, and it technically closes in two weeks on Christmas Day. But that is a pure technicality, because I will certainly stop pulling on the 23rd at the latest, and if I get roped into Xmas food prep, even that date might be questionable. I could extend the merge window rather than cut it short, but I’m not going to. I suspect we all want a nice calm winter break, so if your stuff isn’t ready to be merged early, the solution is to just not merge it yet at all, and wait for 4.11. Just so you all know (I already bcc’d the main merge window suspects in a separate mailing last […]
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 […]
$59 RetroEngine Sigma Retro Game Console is Based on Orange Pi Lite Board (Crowdfunding)
2016 has been the year of retrogaming comeback with products like PocketCHIP, Nintendo NES Classic, GPD Win and quite a few other projects. There will soon be a new option with RetroEngine Sigma, an inexpensive Linux based retro-gaming console based on Allwinner H3 processor. RetroEngine Sigma fanless game console hardware specifications: SoC – Allwinner H3 quad core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU up to 600 MHz System Memory – 512 MB DDR3 Storage – 16 or 32GB micro SD card Video & Audio Output – HDMI port Connectivity – 802.11 b/g/n WiFi USB – 2x USB 2.0 host ports, 1x micro USB OTG port Misc – Programmable status LED, 2 user configurable buttons P1 & P2 Power Supply – 5V/2A via power barrel Dimensions – 110 x 85 x 33.5 mm The specifications look similar, so I went to my little list of Allwinner H3 […]
Qualcomm Starts Sampling of Qualcomm Centriq 2400 ARM Server SoC with Up to 48 ARMv8 Cores
Qualcomm has announced commercial sampling of Qualcomm Centriq 2400 series server SoC built with 10nm FinFET process technology and featuring up to 48 Qualcomm Falkor custom ARMv8 CPU cores “highly optimized to both high performance and power efficiency, and designed to tackle the most common datacenter workloads”. Qualcomm Datacenter Technologies demonstrated the new processor in a Live demo showing Apache, Spark, Java, and Hadoop on Linux running on a SBSA compliant server powered by Qualcomm Centriq 2400 processor, but the company did not provide any further technical details or preliminary benchmark results for the solution. The Qualcomm Centriq 2400 processor series is now sampling to select customers and is expected to be commercially available in H2 2017. That’s about all we know from the press release. However, Linaro have been working on Qualcomm Technologies QDF2432 based board for several months with support for Debian 8.x ‘Jessie’ and CentOS 7 operating […]
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 […]
Hardkernel ODROID-VU8C is 8″ LCD Display and Case Kit for ODROID C1+ and C2 Boards
While it’s quite easy to find displays for development boards, they do not always come with a case, so you’d have to make your own. One easier option for the Raspberry Pi boards is the official Raspberry Pi 7″ LCD touch screen Display, plus RS Premium touchscreen case that selling for $132 in total including Raspberry Pi 3 board. But Hardkernel has now launched their own ODROID-VU8C 8″ Touch Display Shell Kit compatible with ODROID-C1+ and ODROID-C2 boards. Specifications and Kit Contents: 8-inch TFT-LCD with 1024×768 resolution (4:3 ratio) 10 finger capacitive touch input Back-light brightness control with ODROID GPIO PWM Viewing angle : Left 75, Right 75, Up 75, Down 75 degree Screen Dimensions : 189 x 149 x 29 mm Viewable screen size : 162 x121.5 mm (active area) Power Supply – 5V/4A DC to power barrel (powering both the LCD and ODROID ARM Linux board) Power consumption […]
