I’ve recently started using my Android phone as a mobile hotspot with mixed results so instead, I’ve switched to using PinePhone as a hotspot with Manjaro Arm Linux with Plasma Mobile instead, and performance seems much more stable now. Early this year, I received Pinephone with PostMarketOS beta, and after playing with it a bit I did not do much with it so far. But in recent times, I’ve been staying in various places without WiFi, so I purchased a lost cost SIM card with a one-year cellular data plan to be able to work from any location using my Android 10 smartphone (Huawei Y9 Prime 2019) as a mobile hotspot. It works most of the time, but sometimes I have massive packet loss, and the only way to recover is to turn off and on the hotspot, and in some cases even reboot the phone. Playing with settings on […]
Why you should request open-source software for your IoT devices
I usually think of open-source hardware and/or software are enabling skilled people to more easily fix bugs, improve on the design, get feedback from the community, etc… But in a world where IoT devices become more prevalent, there’s another reason why you should request open-source software: Long term support. What made me think about are two things. The first one if that I own WeLoop Hey 3S smartwatch, which I love and wear since March 2018. That’s quite a feat since most cheap devices I own often only last a few months or a year or so. I’m also used to the watch face and Weloop app interface. So what’s the problem exactly? WeLoop company closed on December 31, 2019, and while the app worked fine for about a year after that, recently I have been unable to login to the app to access my data and/or update settings for […]
PineDio indoor LoRa gateway to combine Pine A64-LTS SBC with RAK2287 LoRaWAN concentrator module
RAKwireless has offered Raspberry Pi-based indoor LoRaWAN gateways for development/evaluation purposes for several years, including the more recent RAK7246 LoRaWAN developer gateway equipped with Raspberry Pi Zero W SBC. But there’s will soon be another option, also not directly from RAKwireless, as Pine64 PineDio indoor LoRa gateway will feature RAK2287 LoRaWAN concentrator module connected to Pine A64-LTS single board computer via a custom-designed adapter board. PineDio indoor LoRa gateway preliminary specifications: SoC – Allwinner A64 quad-core Arm Cortex A53 processor @ 1.0 GHz with Mali-400MP2 GPU System Memory – Up to 2GB LPDDR3 Storage – 128Mb SPI boot Flash, MicroSD card slot, optional eMMC flash module Video Output – HDMI 1.4 up to 4K resolution @ 30 Hz Connectivity Gigabit Ethernet Optional WiFi & Bluetooth module LoRaWAN via RAK2287 mini PCIe concentrator module based on Semtech SX1302 with support for RU864, IN865, EU868, AU915, US915, KR920, AS923; external antenna GNSS […]
PinePhone Keyboard to make for a cheaper, albeit slower Cosmo Communicator
Pine64 PinePhone is a popular Linux smartphone among the developers and Linux enthusiasts’ communities and some of the most popular Linux operating systems support by the phone include KDE Plasma Mobile, PostMarket OS, Manjaro, and UBports for an Ubuntu Touch like interface. But soon, you’ll be able to use your PinePhone like a portable Linux computer, a 5.95-inch mini laptop of sorts, that’s similar to the 2-in-1 Cosmo Communicator device, but at a much lower price, albeit with lower performance, thanks to PinePhone Keyboard accessory. The PinePhone Keyboard is not quite ready yet, but Lukasz Erecinski (aka Luke) has shared the progress of the latest version of the prototype, and almost looks like a finished product, albeit we’re told another revision will be made as the tolerances on the keycaps are not suitable. Here are some of the main features we can expect from the keyboard: QWERTY keyboard (by default). […]
InfiniTime 1.0 firmware released for PineTime smartwatch
The PineTime smartwatch was unveiled and first launched in 2019, as a low-cost, open-source wearables development kit/platform for developers wanting to work on firmware development for the Nordic nRF52 powered device. Progress was made on various solutions such as ATCwatch Arduino firmware, and as time passed, the PineTime slowly became more like an “enthusiast-grade” end-user product. This is basically what it has become with the first stable release of InfiniTime firmware, which was selected as the default firmware in September 2020. The main features of InfiniTime 1.0 firmware include: Two clock faces – digital and analog Apps – Stopwatch, music control, navigation, heart rate, as well as Paddle and 2048 games User settings – Display timeout, time format, wake up conditions OTA upgrades via an open-source bootloader based on MCUBoot Heart rate monitoring and step counting Between 3 and 5 days of battery life depending on usage Firmware based on […]
Linux 5.12 – Main Changes, Arm, MIPS and RISC-V Architectures
Linux 5.12 release was expected last Sunday, but Linus Torvalds decided to release one more release candidate, namely Linux 5.12-RC8, to “make sure things are all settled down“, so the latest Linux kernel is now expected this weekend. Tihs should not yield any significant changes, so we can check what’s new in Linux 5.12, notably with regards to Arm, MIPS, and RISC-V architectures often used in SoC’s found in embedded systems. Around two months ago, the release of Linux 5.11 added support for Intel’s software guard extensions (SGX) and Platform Monitoring Technology (PMT), AMD “Van Gogh” and “Dimgrey cavefish” graphics processors, MIPI I3C host controller interfaces, and much more. Some interesting changes in Linux 5.12 include: Added support for ACRN hypervisor designed for IoT & embedded devices Added support for Playstation DualSense & Nintendo 64 game controllers, as well as Nintendo 64 data cartridges Dynamic thermal power management via a […]
Quartz64 Model B SBC revealed, Model A gets hit by production delays
Pine64 unveiled the Quartz64 SBC powered by Rockchip RK3566 processor a few months ago. More specifically they provided details about Quartz64 Model A at the time, a featured-rich variant with SATA, PCIe, multiple display outputs, etc… During the announcement, Pine64 also indicated a Raspberry Pi-sized Quartz Model B was in the works but did not have a prototype to showcase just yet. In the latest Pine64 April update, the community showcased the new board, reported software progress, and information about production delays for Model A. Quartz64 Model B Specifications: SoC – Rockchip RK3566 quad-core Cortex-A55 processor up to 1.8 GHz with Arm Mali-G52 GPU supporting OpenGL ES 1.1/2.0/3.2, OpenCL 2.0, Vulkan 1.1, 0.8 TOPS NPU for AI acceleration System Memory – 2GB to 8GB LPDDR4 Storage 128 Mbit SPI Flash optional eMMC module from 16GB up to 128GB capacity bootable SDHC/SDXC MicroSD card up to 2TB Video Output / Display […]
Chip shortage and high prices threaten supplies of SBCs and other electronics products
A few weeks ago, we started to hear news about a chip shortage for the automotive industry, but the shortage appears to be affecting all sectors now apparently due to a drought in Taiwan where a reservoir could be a risk of being depleted, and TSMC has been asked to reduce its water usage by 7 percent. I’ve also started to see several companies in the maker market warn about shortages and price increases. Pine64 announced it would only open pre-order for PinePhone, PinebookPro, PineTab, and other products once they could secure stocks of components, and while they hope to be able to do so within this month, there’s no guarantee. (1/2) [PSA] Re. availability of #PinePhone, #PinebookPro, #PineTab, etc., Due to component shortages, component price-increases & related issues, we will only open orders/pre-orders when production is securely underway. We are more cautious than usual, also for your sake (…) […]
