WeLoop Hey 3S Sports Smartwatch Review – Part 1: Specifications, Unboxing, First Try with Android App(s)

It’s been a while since I have reviewed a smartwatch or fitness tracker, simply because I found most devices to be lacking, and break easily after a few weeks or months. It’s also difficult to find a device that combines long battery life, waterproofness, a decent screen, and all that at a reasonable price. But I decided to give it another try when Geekbuying asked me whether I was interested in reviewing WeLoop Hey 3S sports smartwatch with 5 ATM waterproofness, a standby time of 30 days, a color display, an optical HRM, and built-in GPS. I’ve just received it , so I’ll start by posting specifications about the watch, and checkout what’s inside the package. Weloop Hey 3S Specifications Display – 1.28″ color memory LCD display with 176×176 resolution, touchscreen Connectivity – Bluetooth 4.0 LE, built-in GPS Sensors – Heart rate monitor Battery – 270 mAh LiPo battery good […]

HEIF Image Container Format Leverages H.265/HEVC to Store Photos and Image Sequences

A few years ago, Google introduced WebP image format leveraging VP8 video codec, and the Moving Picture Experts Group (MPEG) has decided to do something similar but instead of using VP8, they went with their own H.265/HEVC video codec for HEIF image container format. HEIF stands for High Efficiency Image File, and is defined by ISO/IEC 23008-12 (MPEG-H Part 12). The storage of the data is based on ISO Base Media File Format (ISOBMFF), and HEIF appears to be especially useful to replace animated GIFs file with better quality and much lower sizes, as well as burst photos. HEIF also appears to compress a little better than JPEG photo with similar quality, but HEIF appears to fallback to JPEG codec sometimes, so it may be improvement in the way metadata is handled? The comparison table show the different features between HEIF and other well-known image format (JEG, WebP, GIF, etc…). […]

ASRock J5005-ITX Pentium J5005 Motherboard Coming Soon for around $120 and Up

Several products based on Gemini Lake processors have already been announced, and some are already available through pre-orders, but so far, I’ve not seen many retail hardware based on Intel Pentium J5005, the most powerful processor of the family, except for one Intel NUC. ASRock J5005-ITX motherboard brings another option, and while it had been expected for a while, the company has now setup a proper product page, and the motherboard can be seen as “coming soon” for about $120 and up (excluding VAT) on some websites like Alzashop (in Europe) or Kakaku (in Japan). ASRock J5005-ITX motherboard specifications: SoC – Intel Pentium J5005 quad core processor @ 1.50/2.8 GHz with 18EU Intel UHD Graphics 605 up to 800 MHz; 10W TDP System Memory – 2x DDR4-2400/2133 SO-DIMM slots up to 8GB (2GB per module not supported) Storage 2x SATA3 6.0 Gb/s connectors, support NCQ, AHCI and Hot Plug 2x […]

Android Wear Becomes “Wear OS by Google”

Android Wear is an operating systems for wearables based on Android, but it may be confusing to (some) consumers, since an Android Wear watch may pair with an iPhone and an Android phone is not requires. Google actually reports one third of Android Wear watch users also own an iPhone, so the company has now decided to rename Android Wear to “Wear OS by Google“. Apart from the name change and new micro website, everything remains the same. Now if they could also change “Android TV” to “TV OS by Google” that would also prevent an other type of confusion among users…

How to Run Linux on RISC-V with QEMU Emulator

RISC-V open-source architecture is starting to become more and more interesting thanks to the growing RISC-V hardware & software ecosystem, and with the recent release of HiFive Unleashed, we even have a board capable of running Linux. The only problem: it costs $999. But luckily, it’s possible to experiment with Linux on RISC-V without extra hardware, just using your current PC. Imperas offers a commercial solution working on both Windows and Linux that relies on busybear-linux RISC-V Linux root filesystem comprised of busybox and dropbear SSH server. The rootfs also works with QEMU, so I tried it in Ubuntu 16.04. The instructions on Github are quite easy to follow. My computer is powered by an AMD FX8350 processor coupled with 16GB RAM, and the whole process took around 2 hours, so better use the fastest computer possible. It also requires around 26 GB of storage on your build machine. First, […]

STMicro VL53L1X Time of Flight (ToF) Sensor Extends Distance Measurement Range up to 4 Meters

STMicroElectronics VL53L0X ToF (Time-of-flight) range sensor is a tiny chip that can accurately and quickly measure distance up to 2 meters using laser light. I had the chance to test the sensor via TinyLIDAR board connected Arduino and Raspberry Pi, and found it was a great little sensor. TinyLIDAR includes an STM32 MCU, but you can also find standalone board for as low as about $4 shipped on Aliexpress. However, if 2 meters is too short a range for your project, the good news is that STMicro has now launched VL53L1X ToF “FlightSense” sensor with a range of up to 4 meters. VL53L1X is pin-to-pin compatible with VL53L0X, so existing PCBs could be re-used with the new sensor. STMicro VL53L1X main specifications: Emitter: 940 nm invisible laser (Class1) SPAD (single photon avalanche diode) receiving array with integrated lens Low-power microcontroller running advanced digital firmware Distance Ranging up to 4 meters […]

ACRN is an Open Source Hypervisor Built for IoT Device Development

ACRN – pronounced “acorn” – is an open source reference hypervisor with a small footprint, real-time capabilities, adaptability with support for Linux, Android, and RTOS guest operating systems, built for safety critical code in mind, and specifically designed for IoT and embedded devices. The project is managed / supported by the Linux Foundation. A few more details about some of the key features of the solution: Two main components: the hypervisor itself, and its device model complete with rich I/O mediators managed by Linux-based Service OS (SOS). Small footprint – Approx. 25K lines of code (LOC) for ACRN hypervisor against 156K LOC for datacenter-centric hypervisors. Real Time – Low latency, enables faster boot time, improves overall responsiveness with hardware communication Adaptability – Multi-OS support for guest operating systems like Linux, Android, RTOSes… Safety Criticality – Safety critical workloads have priority, isolation of safety critical workloads Built for Embedded IoT – Virtualization […]
