High-Efficiency Wireless (HEW), better known as 802.11ax, is a new WiFi standard that is supposed to deliver up to 10 Gbps bandwidth over 2.4 and 5.0 GHz frequencies, and improve the average throughput per user by a factor of at least 4 times in dense environments. Several draft of the specifications have been voted on, but the latest 802.11ax timeline seems to indicate the final 802.11ax specifications will only be approved sometimes in 2019. This has not prevented companies to announce or unveil 802.11ax SoC or solutions based on the draft specifications, as we’ve seen in the past with NXP Layerscape LA1575 programmable WiSoC, Qualcomm gateway reference design, and Broadcom Max WiFi chips. Marvell has now joined the fray with their 802.11ax wireless portfolio. All Marvell 802.1ax WiSoCs support all using uplink & download OFDMA / MU-MIMO, 1024 QAM, off-channel spectrum scanning, dedicated in-service monitoring, and precision location. Three SKUs […]
Turn Your Raspberry Pi into a “Smartphone” or Cellular IoT Gateway with PiTalk 3G HAT (Crowdfunding)
The Raspberry Pi boards are used in a countless number of projects, and some of those turn one of Raspberry Pi boards into a (thick) smartphone powered by Linux. The first one was probably PiPhone based on Raspberry Pi 1 Model B, and other followed suit such as TyTelli based on Raspberry Pi Model A+, and more recently ZeroPhone powered, as its name implies, by Raspberry Pi Zero board. UK based SB Components Ltd is offering another option with their PiTalk HAT based on a Quectel 3G UMTS module, and kits adding a 3.2″ to 5″ display, an optional camera, and/or Raspberry Pi 3 board. PiTalk board specifications: Cellular Connectivity Quectel UC15 3G/2G UMTS/HSDPA and GSM/GPRS/EDGE module with up to 3.6 Mbps download, 384 Kbps upload SMA antenna connector Push push SIM card holder Voice, SMS and data support Audio – 3.5 mm audio jack, speaker and mic support via […]
Anavi Light pHAT Adds RGB Light Strip Support to Raspberry Pi Boards (Crowdfunding)
He works as a software engineer for his main job, but Leon ANAVI is apparently enjoying his hobby of designing open source hardware, as after RabbitMax Flex home automation HAT, and ANAVI Infrared pHAT with IR transmitter and receiver, he has come up with as third project: Anavi Light pHat, an add-on board for Raspberry Pi 3/Zero (W) that adds support for RGB light strips. Light pHAT specifications: Compatible with 40-pin Raspberry Pi header EEPROM with board manufacturer information and a device tree fragment Terminal block for a 12V RGB LED strip 3x 4-pin I2C headers for sensor modules 1x 3-pin header for PIR motion sensor 1x 4-pin UART header for debugging Dimensions – pHAT form factor You first need to connect the pHAT to your board, and then LED strip, and you can then control the lights using Home Assistant open source home automation platform, with the strip integrated […]
Azulle Byte3 Mini PC Review – Windows 10, Linux Support, Benchmarks, and Video Playback
The Azulle Byte3 is a fanless Apollo Lake device featuring both M.2 slot and a SATA connector, as well as supporting HDMI and VGA. It includes USB (both 2.0 and 3.0 including a Type-C port) as well as Gigabit Ethernet: It features an Apollo Lake N3450 SoC and comes with 32GB of storage plus an option of either 4GB or 8GB of RAM and a further option of either with or without Windows 10 Pro meaning Linux users can save around USD 20. Azulle provided me with a device for review and it came in a presentation box complete with a power adapter, and remote control together with a quick guide pamphlet. Whilst the power adapter includes an interchangeable plug it only came with one suitable for the US. Looking at the detail specifications: it is important to realize that the Type-C USB is USB 3.0 which […]
Rockchip RK3288 To Be Phased Out Soon? GPD XD+ Android Console To Get Mediatek MT8176 SoC, 4GB RAM Upgrade
[Update: I have now seen an email exchange with ASUS replying that Rockchip RK3288 will still be in production for 5 years, so GPD claims that manufacturing will stop for RK3288 may be incorrect, or misunderstood Update 2: Rockchip has now confirmed RK3288 will not be phased out. So I’m guessing there may have been info lost in translation with GPD simply not manufacturing their own RK3288 board anymore] Rockchip RK3288 32-bit Arm processor was first spotted in a company presentation in the summer of 2013, before being announced – with some confusion (Cortex A12 vs A17) – at CES 2014 in January. The quad core Cortex A17 processor had then its moments of glory with inclusion in products such as Chromebooks (2015), and ASUS Tinker board SBC earlier this year. Another product based on the processor is GPD XD Android game console, but according to a report on reddit, […]
Meet the First Windows 10 Arm “Always Connected PCs” – HP Envy x2 (2017) and ASUS NovaGo TP370
Qualcomm and Microsoft showcased some Snapdragon 835 based Windows 10 “Mobile PCs” at Computex 2017 last June, and while the press was allowed film the demo, the device could only be operated by a Qualcomm employee. But both companies and their partners have made progress, and at the Snapdragon Technology Summit, Qualcomm announced “Always Connected PCs” which will run Windows 10, be always on and always connected at Gigabit LTE speeds, and support all-day battery life while keeping thin and fanless designs. all while incorporating Windows 10. HP and ASUS unveiled their very own “Always Connected PCs”, respectively Envy X2 and Novago TP370. What I used to call laptop or in this case 2-in-1 hybrid (laptop) is now apparently called “Always Connected PC”, but in any case let’s have a closer look at both devices. HP Envy x2 (2017) Specifications: SoC – Qualcomm Snapdragon 835 Mobile Processor @ 2.6GHz with Adreno […]
Sega Genesis Flashback Retro Game Console is Powered by “Monkey King 3.6” Processor, Runs Android
Retro gaming is cool again with products like Nintendo NES Classic / SNES Classic, DIY solutions based on firmware like RetrOrangePi, and the upcoming Atari console among others. Another model is AtGames Sega Genesis Flashback, a smaller replica of Sega Model 1 Genesis with 85 pre-loaded games including the Sonic series, Mortal Kombat series, Phantasy Star series, and Shining Force series games. The console ships with two wireless controllers, connect to your TV via HDMI with 720p resolution, and includes a cartridge slot that works with Sega Genesis and Mega Drive cartridges. The console has been out for several months, and it would be an understatement to say reviews are not very positive with titles / bylines such as “do not buy” (partially because the console requires a power adapter….), This Genesis does not do what Nintendoes, or “More like Trashback“. But what caught my eyes is ETA Prime’s Sega Genesis Flashback HD […]
Mozilla Adds HTML5 AV1 Video Support to Firefox 59 Nightly Builds
Last year, we wrote about AV1 royalty-free open source video codec managed by the Alliance for Open Media (AOMedia), a non-profit organization with members such as Amazon, Cisco, Google, Intel, Microsoft, Mozilla, and other companies. Eventually AV1 should be 25 to 35% more efficiency than H.265 or VP9, but encoding will be slower, and at the time, my AMD FX8350 based computer could encode CIF (352×288) video at less than 0.5 fps, and I had to use command line tools to encode and decode/playback the videos. But thing are progressing nicely, and it’s now possible to stream AV1 video with HTML5 / in Firefox 59.0 (nightly) using Bitmovin Player. If you are using Ubuntu, you can also install Firefox nightly as follow:
1 2 3 |
sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa sudo apt-get update sudo apt-get install firefox-trunk |
Start it and visit the demo page to stream an AV1 MPEG-DASH/HLS stream in your web browser. It works from 360p @ 200 Kbps up to 720p […]
