LG 24UD58-B 24″ 4K UHD IPS Monitor Sells for $219

When I bought my first 4K UHD TV in January 2015, I had to pay around $600 for LG 42UB820T 42″ model. It was good for about a year, after which it started to fail, and was somewhat outdated due to the lack of HDR support. Over four years later, prices for 4K hardware as dropped significantly, as as pointed out by Michael Larabel of Phoronix, it’s now possible to buy a 24″ 4K UHD display for just $219. LG 24UD58-B 24″ 4K UHD IPS monitor also have the advantage of supporting FreeSync helping avoid stuttering and tearing in games. LG 24UD58-B specifications: Screen Size – 23.8″ up to 3840×2160 resolution (16:9 aspect radio) Panel Type – IPS Color Gamut (CIE 1931) – NTSC 72% Color Depth (Number of Colors) – 10bit(8bit + A-FRC) Response Time – 5ms GTG Refresh Rate – 60Hz Brightness – 250 cd/m2 Contrast Ratio – […]

Semtech Releases Open Source Software for LoRa Gateways & Devices

Semtech has released open source software for LoRa-based gateways including LoRa Basic Station packet forwarder for Linux-based gateways, LoRa Basic MAC implementation of the LoRa Alliance’s LoRaWAN specification, and LoRa Basic loader bootloader capable of handling firmware updates. All three components are available for free under a revised 3-Clause BSD license. LoRa Basic Station supports LoRaWAN Classes A, B, and C, presents a unified radio abstraction layer supporting Concentrator Reference Designs v1.5 and v2, and implements various backend protocols. Apart from mbedTLS and libloragw/-v2, it does not rely on external dependencies, the code is written in C language only, and easily portable to Linux gateways and embedded systems. LoRa Basic MAC is a fork of IBM’s LMiC library, also implemented in C language, supports multiple regions selectable at compile and/or run time, and can handle Class A, Class B, and Class C devices. Basic MAC uses LoRa Basic loader to […]

Facebook Oculus Quest Standalone VR Headset Launched for $399 and up

One year ago, Facebook introduced their very first standalone virtual reality headset with Oculus Go. At $199 the price was fairly attractive, but the headset only supported 3DOF motion tracking. The company announced a new model at F8 2019. Oculus Quest is equipped with a more powerful Snapdragon 835 processor, two 1600 x 1440 displays, and support for 6DOF (degrees of freedom) virtual reality thanks to two handheld motion controllers. Oculus Quest specifications: SoC – Qualcomm Snapdragon 835 octa-core processor with 4x high performance Kryo 280 cores @ 2.20 GHz/ 2.30 GHz (single core operation), 4x low power Kryo 280 cores @ 1.9 GHz, Adreno 540 GPU System Memory – 4GB RAM Storage – 64GB or 128GB flash storage Display – 2x 1600×1440 OLED displays up to 72 Hz Camera – 4x wide-angle tracking cameras for inside-out position tracking Audio – Integrated speakers, 2x 3.5mm audio jacks Battery – Lithium-Ion […]

Rockchip RK1808 Datasheet, TRM, Schematics and Linux SDK Released

Rockchip RK1808 is the first chip from the company fully dedicated to artificial intelligence applications. The Neural Processing Unit (NPU) features an accelerator delivering up to 3.0 TOPS and is coupled with two low power Arm Cortex-A35 cores allowing it to run Linux. We’ve had the specifications for RK1808 for a while, but the company has recently posted hardware and software resources on their open source website. On the hardware side we’ve got: RK1808 Technical Reference Manual (TRM) RK1808 datasheet PDF Schematics for the company’s official RK1808-EVB On the software side we can get the Linux SDK from Github as explained in the Wiki:

git clone https://github.com/rockchip-linux/repo
mkdir linux
cd linux
../repo/repo init --repo-url=https://github.com/rockchip-linux/repo -u https://github.com/rockchip-linux/manifests -b master -m rk1808_linux_release.xml
../repo/repo sync

git clone https://github.com/rockchip-linux/repo

mkdir linux

cd linux

../repo/repo init --repo-url=https://github.com/rockchip-linux/repo -u https://github.com/rockchip-linux/manifests -b master -m rk1808_linux_release.xml

../repo/repo sync

Finally configure the build and start the build process:

sudo apt install liblz4-tool build-essential
source envsetup.sh rockchip_rk1808
./build.sh

sudo apt install liblz4-tool build-essential

source envsetup.sh rockchip_rk1808

./build.sh

After a while, or more accurately close to two hours on a Laptop with Ryzen 7 2700U processor, 8GB RAM, and hard drive, we’ll get U-boot, Linux, buildroot based rootfs, and firmware files and in […]

Battery powered MEGO Portable Power Supply fits into Breadboards

Breadboard power supplies like MB102 have been around for years, and some even designed a variable power supply for breadboards, but EVO-IN-MOTION MEGO looks much neater as a fully enclosed power supply, 4 to 24V output, fitted with a LiPo battery, and a display to show current voltage. MEGO enabled on-the-go breadboard projects without any cables for the power supply. Just connect the power supply, and you’re good to go with power delivered from the built-in battery. MEGO power supply specifications: Output Voltage – 4-24V DC Maximum Power – 6W Safety – Overload protection; short circuit protection Typical Power Efficiency – 88% Voltage Display Accuracy – <1% Ripple Voltage – <1% Load Regulation – 270mV Battery – 7.4Whs (2,000 mAh @ 3.7V) Misc – Power button;, adjust knob for output voltage; low battery and charging LEDs Dimensions – 73 x 59 x 32 mm Weight – 100 grams Temperature Range […]

Giggle Score Says ODROID-N2 Best Value, Raspberry Pi Zero Worst Value

[Update May 7, 2019: Giggle Score has been updated to use 7-zip to benchmark the boards instead of sysbench, and the “best value” rankings are now quite different] People like to compare single board computers, and usually want to have a simple answer as to which is better than the others. But in practice it’s impossible, because the beauty of SBCs is that they are so versatile and can be used in a wide variety of project, and that means in some cases the “best board” may be completely useless to you since it lacks a critical feature and interface for YOUR project be it H.265 video encoding or a MIPI DSI display interface. Still, it’s still always fun to look at benchmark scores and trying to compare SBCs, and for projects that mostly require CPU processing power it may also be useful. Robbie Ferguson has been developing and maintaining […]
