postmarketOS Linux Mobile OS Supports Over 100 Devices

postmarketOS

postmarketOS is a Linux operating system that was first unveiled in 2017, with the developers aiming to provide long term support in order to extend the life of existing phones.  The operating system is based on Alpine Linux with touch-screen optimization, and the goal is to provide updates, including security updates, for at least 10 years just like you would get on a computer. The project was really getting started at the time, but now the community has provided an update for the first 600 days of development, and over 100 devices are now supported, mostly smartphones such as Google Pixel 3 XL or Motorola Droid 4, but also some SBCs, for instance, Pine A64-LTS and various Raspberry Pi boards. “Supported” means the 112 devices listed can boot postmarketOS, but the operating system is still considered to be alpha software, and for example, if you look at the features matrix in the list of the device, you’ll find only LG …

XinaBox’s xChips Enable Modular Electronics for Makers & STEM Education

Xinabox xCHIPS ESP8266 UV Index Monitor

So today, I decided to have a look a 96Boards website to see if there was anything new from the community, and I came accross “X in a Box B901“, an “☒CHIP is designed to interface with the 96 Boards, such as the Dragonboard 410c. This provides an interface to support the ☒CHIP ecosystem, adding support for many additional sensors etc…” I had no idea what it was all about, so obviously I had to investigate. Xinabox (X in a Box) is an ecosystem of modular electronics boards used for developing, making products and learning. There are now over 70 modular xChip” with cores/CPUs, sensors, power, communication, output, and storage. They are interconnected together without wires, soldering, breadboards, and adapters are provided for Raspberry Pi, 96Boards, and other development boards. xChips can be sorted into 8 categories: Cores – MCU/CPI cores based on Microchip ATMega328P, SAMD21, ESP8266, or ESP32 with or without a LoRa radio Bridges – Used to connect …

$16 Raspberry Pi Case Integrates a 3.5″ Touchscreen Display

Display Case for Raspberry Pi 3

Most Raspberry Pi cases are not really newsworthy, but there’s an unnamed case for Raspberry Pi 2 & 3 boards sold for $15.99 on Banggood that looks like a normal case, except the top cover is replaces with a 3.5″ touchscreen display, and the kit also ships with a stylus. Key features of the display: LCD Type – TFT LCD Interface – SPI Touch Screen Type – Resistive Touch Screen Controller – XPT2046 Colors – 65536 Backlight – LED Resolution – 320×480 (Pixel) Aspect Ratio – 8:5 There are two ways to assemble the kit. Either with the 3.5″ display and no fan, or without display, but a top cover including a fan. I’ve not sure why would anyone would purchase this kit without using the display but at least you know that’s an option. There are ready-to-use Raspbian images for Raspberry Pi 3 and Raspberry Pi 3 B+, but I doubt they’ll be updated, so instead, you may want …

FOSDEM 2019 Open Source Developers Meeting Schedule

FOSDEM 2019

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where developers meet on the first week-end of February to discuss open source software & hardware projects. FOSDEM 2019 will take place on February 2 & 3, and the schedule has already been published with 671 speakers scheduled to speak in 711 events themselves sorted in 62 tracks. Like every year, I’ll create a virtual schedule based on some of the sessions most relevant to this blog in tracks such as  open hardware, open media, RISC-V, and hardware enablement tracks. February 2 10:30 – 10:55 – VkRunner: a Vulkan shader test tool by Neil Roberts A presentation of VkRunner which is a tool to help test the compiler in your Vulkan driver using simple high-level scripts. Perhaps the largest part of developing a modern graphics driver revolves around getting the compiler to generate the correct code. In order to achieve this, extensive …

Linux 4.20 Release – Main Changes, Arm and MIPS Architectures

Linux 4.20 Changelog

After Greg K-H handling Linux 4.19 release, Linus Torvalds is back at the helm, and released Linux 4.20 just before Christmas: Let’s face it, last week wasn’t quite as quiet as I would have hoped for, but there really doesn’t seem to be any point to delay 4.20 because everybody is already taking a break. And it’s not like there are any known issues, it’s just that the shortlog below is a bit longer than I would have wished for. Nothing screams “oh, that’s scary”, though. And as part of the “everybody is already taking a break”, I can happily report that I already have quite a few early pull requests in my inbox. I encouraged people to get it over and done with, so that people can just relax over the year-end holidays. In fact, I probably won’t start pulling for a couple of days, but otherwise let’s just try to keep to the normal merge window schedule, even …

Steam Link Beta now Available for Raspberry Pi 3 / 3B+

Raspberry Pi 3 Steam Link

Steam is a digital distribution platform developed by Valve Corporation for purchasing and playing video games that was first launched in 2003 for Windows computer only. Since then Mac OS (2010), Linux / Ubuntu, as well as mobile devices running Android & iOS (2012) have been supported in Steam.

However more recently, the company released Steam Link app that allows players to stream games to their mobile devices, while being rendering on more powerful machines.  The good news is that Steam Link (beta) has now been released for Raspberry Pi 3 / 3B + boards. All you need is either board running Raspbian Stretch, and install Steam Link as follows: Once the app is installed launch it in the command line with steamlink, or launch it from the Games menu in the desktop environment. Steam Link support has already been added to RetroPie, and ETA PRIME …

MiniNodes Raspberry Pi 3 CoM Carrier Board Takes up to 5 Compute Modules 3

mIninodes raspberry pi com carrier board

Mininodes is known for their hosting services based on Arm development boards such as Cubieboard2, 96Boards Hikey, or Raspberry Pi 3, but the company unveiled their own hardware platform at Arm TechCon 2018 with miniNodes Raspberry Pi CoM (Computer-on-Module) carrier board that takes up to five Raspberry Pi Compute Modules 3. Beside the five sockets for CM3 / CM3L modules, the carrier board is also equipped with a gigabit Ethernet switch and RJ45 connector, as well as a DC jack to power the whole setup. The white round logo on the board most certainly means mininodes designed the board with Gumstix Geppeto web platform that allows you to fairly easily design your own custom boards in a web browser without having to draw schematics, and then handle the PCB layout. The company explains the Raspberry Pi 3 CoM Carrier Board can be used to provide edge compute capacity in remote environments, industrial settings, or space constrained locations. Alternatively, you could …

Diskio Pi 13.3″ DIY Tablet Kit for Raspberry Pi – Take 2 on Kickstarter

Diskio Pi with ODROID-C2 Board

Diskio Pi was a DIY tablet kit for Raspberry Pi, ODROID-C2/XU4 and other compatible boards with a 13.3″ Full HD display that launched last year on Kickstarter. But the project failed likely due to the high costs (350 Euros and up for early bird pledges without battery nor SBC) and an elevated funding target of 400,000 Euros. But the team did not give up, worked on reducing costs, improved the design, and recently relaunched Diskio Pi on Kickstarter with a more achievable 52,096 Euros target, and reasonable pricing with rewards starting at 189 Euros including VAT. Diskio Pi “basic” DIY tablet kit content and main specifications: Display – Innolux 13.3″ TFT/IPS display with 1920×1080 resolution, WLED backlight + 10-point touch capacitive panel connected over USB 2.0 Video control board with HDMI 1.4 to eDP converter, stereo amplifier, and 2x 1W speakers Daughter board with Genesys USB hub, 9V to 5V/4A buck converter, temperature control, HDMI external output Ethernet and audio …
