PineTime Smartwatch Specifications Released, Availability Scheduled for H1 2020

PineTime Charging Cradle & Heart Monitor

A couple of weeks ago, we covered PineTime smartwatch for PinePhone Linux smartphone that should be launched next year for around $25. At the time we had limited information from a Tweet as well as information provided by TL Lim, founder of Pine64 community, such as the watch would be based on Nordic Semi nRF52832 or nRF52840 multi-protocol WiSoC. But we now have much more details about specs and other details can be found in the Wiki. PineTime specifications: SoC (undecided, one or the other. See differences between nRF52832 and nRF52840 for details) Nordic Semiconductor nRF52832 Arm Cortex-M4F MCU @ 64 MHz with 512KB Flash, 64KB SRAM, Bluetooth 5 (no long range) Nordic Semiconductor nRF52840 Arm Cortex-M4F MCU with 1MB flash, 256KB flash, Bluetooth 5 (long range), 802.15.4 (e.g. for Zigbee), Arm Trustzone, etc… Storage – 8MB SPI NOR Flash (final product may use 16MB flash instead) Display – 1.3″ […]

HEGduino IoT Real-time Neurofeedback Platform Aims to Increase Brain Function (Crowdfunding)

The HEGduino Alaskit has developed a way to measure the blood-oxygen levels in the brain and create a biofeedback system that is said to increase brain function. The new tech is called HEGduino and is a connection between a biofeedback method and an IoT platform. Past Reported Medical SBCs In the past, CNX has covered several health-based platforms for the Raspberry Pi (Healthy Pi HAT) and ESP32 (Hearty Patch, ECG reader) medical SBCs. HEG Particulars The HEG in HEGduino stands for Hemoencephalography, a neurofeedback technique similar to EEG measurements in brainwave activity. The difference is HEG can measure neural activity based on neurovascular coupling, which can be approached through near infrared and passive infrared techniques – both of which are ways to cerebral blood flow can be matched to metabolic activity. HEG Functions The HEG is a way to alter brain function through a series of “training” sessions based […]

Linux 5.3 Release – Main Changes, Arm, MIPS & RISC-V Architectures

Linus Torvalds has just announced the release of Linux 5.3: So we’ve had a fairly quiet last week, but I think it was good that we ended up having that extra week and the final rc8. Even if the reason for that extra week was my travel schedule rather than any pending issues, we ended up having a few good fixes come in, including some for some bad btrfs behavior. Yeah, there’s some unnecessary noise in there too (like the speling fixes), but we also had several last-minute reverts for things that caused issues. One _particularly_ last-minute revert is the top-most commit (ignoring the version change itself) done just before the release, and while it’s very annoying, it’s perhaps also instructive. What’s instructive about it is that I reverted a commit that wasn’t actually buggy. In fact, it was doing exactly what it set out to do, and did it […]

PineTime is a $25 Smartwatch / Companion for PinePhone Linux Phone

We’ve recently seen Linux smartphones are coming in a few weeks or months, but the $150 PinePhone may not come alone, and soon be joined by a $25 companion, namely PineTime smartwatch. That’s what we learned through a tweet by Pine64 explaining the PineTime is a Linux smartphone companion that can run FreeRTOS or Arm Mbed operating systems. It will be a side-project however, and the focus is still on PinePhone and Pinebook Pro, meaning it will take a while depending on the level of community engagement. Available information is limited to the discussion in the tweet at this stage, but we do know the watch will be made of zinc alloy & plastic, come with a charging dock, a 20 mm wristband, an heart-rate monitor and last several days on a charge. We’ve also seen people interested in porting ZephyrOS to the watch, and others would like to make […]

Huawei Releases their Open Source Ark Compiler for HarmonyOS

Back in May, there were rumors Huawei was working on HongMeng OS as an alternative to Android mobile operating systems, as the OS was brought to light due to US sanctions against the company. The new operating system was later confirmed and will be called HarmonyOS outside of China. A few days ago I received a tip in Chinese with this link explaining Huawei had released the open-source Ark compiler for HarmonyOS aka OpenArkCompiler. The compiler works with Java apps and converts the source into AArch64 binaries. The illustration below implies it should also work with C, C++, JavaScript, and Kotlin programming languages. Three links were shared in the announcement: The official website – https://www.openarkcompiler.cn/home The code hosting website – https://code.opensource.huaweicloud.com/openarkcompiler/openarkcompiler/home A mirror for the code – https://gitee.com/harmonyos/OpenArkCompiler As a side note, I had never heard about Gitee, and the site is an alternative to Github in China, which may […]
