Xiaomi Introduces Mi Box 3c and 3s TV Boxes with Artificial Intelligence Capabilities

Xiaomi has launched two new upgraded models based on their Mi Box 3 TV box powered by Amlogic S905-H processor, with Mi Box 3s with Amlogic S905X-H and 2GB RAM, and Mi Box 3c with Amlogic S905-H and 1 GB RAM. Beside the box hardware changes, the most significant updates are the replacement of MIUI TV interface by allegedly the first set-top box system with AI in the world, which the company calls Patch Wall, as well as Mi Touch IR remote control which include a touch ring in place of the usual arrow keys (3s only). Xiaomi Mi Box 3s specifications: SoC – Amlogic S905X-H quad core ARM Cortex A53 processor + Mali-450MP GPU System memory – 2GB RAM Storage – 8GB eMMC flash Video Output – HDMI2.0a port with HDR support + AV port Audio – Dolby and DTS support Connectivity – WiFi 802.11ac Dual band 2.4 / […]

Make-WiFi-Fast Project Massively Improves WiFi Performance of Busy WiFi Routers

WiFi is a great way to add connectivity to a large group of people, but once everybody tries to connect at the same time, the network often becomes unusable due to very high latency, a problem that can occur on servers on the ISP side too, and that’s usually caused by excessive buffering, Bufferbloat. The Bufferbloat project aims to resolve this issue with both routers using CoDel and fq_codel algorithms, as well as WiFi via Make-WiFi-Fast project. Dave Täht gave a presentation of his work on Make-WiFi-Fast project entitled “Fixing WiFi Latency… Finally“showing how latency was reduced from seconds to milliseconds. It’s quite technical, but two slides of the presentation clearly shows the progress made. The first chart shows 100 stations connecting to a website using unpatched code with the top of the chart showing the bandwidth per node in MBits/s, while the lower part showing latency in ms. We […]

Meet Body Heat Powered MATRIX PowerWatch, The Activity Tracker You Never Need to Charge (Crowdfunding)

There are currently several issues with wearables that makes it sub-optimal devices, from displays that can’t be always-on, to unreliable sensors, and in my experience pretty poor reliability, as I’ve managed to go through 4 fitness trackers / smartwatches in a year. Another issue is that contrary to typical watches lasting 10 years with a coin cell battery, most wearables require to be charge every few days, weeks, with the very best devices being chargers every few months. MATRIX PowerWatch promises to solve latter, as you will never need to ever charge it since it charges itself by harvesting energy using your body heat. The company promotes it as a smartwatch, but it’s closer to an activity tracker, since you can’t keep the Bluetooth LE connection all the time in order to receive notifications to your smartphone. It’s basically used to show time, track your activity and sleep patterns, and […]

GR-LoRa is a Reverse-Engineered Open Source Implementation of LoRa PHY

LPWAN standards such as LoRa or Sigfox allow you to transmit data over long distance, at ultra low power (up to 10 years on a AA battery), and for free if your use your own network (P2P or gateway), or a few dollars per years if you go through a network provider. The low cost is possible since those standards rely on 900 MHz ISM bands, meaning nobody has to pay millions of dollars to the government to obtain a license fee. Matt Knight looked at LoRa, and while Level 2 and 3 of the protocol (LoRaWan) has public documentation, Level 1 (LoRa PHY) is proprietary and the standard is proprietary. So he decided to reverse-engineer LoRa PHY using Microchip RN2903 based LoRa Technology Mote and Ettus B210 USB software defined radio, and software packages and tools such as Python and GNU Radio to successfully deliver GR-LoRa open source “GNU Radio […]

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 […]

Marvin is a Plug and Play, Arduino Compatible, LoRa USB IoT Development Board (Crowdfunding)

LoRa appears to be one of the most popular LPWAN standards so far, with hobbyist development boards such as LoPy or LoRaONE, and we’ll soon have at least one more choice thanks to Marvin, a LoRa development board with a full size USB port. Marvin board specifications: MCU – Atmel/Microchip ATmega32u AVR MCU (same as Arduino Leonardo board) Connectivity – LoRa via Microchip RN2483; Supports both 868 MHz and 433 MHz frequency bands, on-board antenna USB – 1x USB, 1x micro USB port for power and programming Debugging – USB, and ISP header Expansion – 5x Grove connectors Power Supply – 5V via USB port Dimensions – N/A, but similar to USB flash drive The board can be programmed with the Arduino IDE, and they mention IBM Bluemix platform, and Node-RED, but overall details about documentation and software are scarce right now. One of the advantage of this form factor is […]

Embedded Linux Conference and OpenIoT Summit Europe 2016 Videos are Now Available Online

The Embedded Linux Conference and OpenIoT Summit Europe 2016 conferences took place on October 11 – 13 in Berlin, Germany, with many interesting talks about Linux, development boards, power management, embedded systems, software optimization, tools, and so on, as well as a few keynotes. The Linux Foundation has recorded most talks and keynotes, and made the videos available on their website. A free registration is required, and will redirect you to the full unlisted playlist on YouTube. Tim Bird keynote can be watch directly without registration. You can also download the slides for each presentation. Thanks to Harley for the tip.
