I’ve reviewed CHUWI LapBook 14.1 laptop earlier this year with an Intel Celeron N3450 Apollo Lake processor, 14.1″ Full HD display and 4GB RAM, and found it to work reasonably well for the price in Windows 10, as well as Ubuntu 17.04. The company has been working on another model called CHUWI LapBook 12.3 with the same processor, but a smaller yet higher resolution 12.3″ 2K display, more memory (6GB RAM), 64GB eMMC flash, and support for M.2 SSDs up to 256 GB. CHUWI LapBook 12.3 specifications with highlight in bold showing differences against LapBook 14.1 model: SoC – Intel Celeron N3450 quad core “Apollo Lake” processor @ 1.1 GHz / 2.2 GHz (Burst frequency) and 12 EU Intel HD graphics 500 @ 200 MHz / 700 MHz (Burst freq.); 6W TDP System Memory – 6GB DDR3 Storage – 64 GB eMMC flash + micro SD slot up to 128 […]
Selecting a Micro USB Cable to Power Development Boards or Charge Phones
Yesterday one person contacted me on Facebook asking me whether there was any chance of me doing a “which usd-micro usb cable is best”, as there’s not much clear information on the Internet. His purpose was to charge his phone, but many development boards come with a micro USB port, and I’ve read many comments about powering the board. It also happened to me, and the main cause can either be the power supply which does not work as rated (usually 5V/2A), or the micro USB cable which may have a resistance a little to high leading to voltage drops. You’ll know you may have a power problem when the board refuses to boot, and usually boot loop, or randomly reboots especially under high load. The first solution is to get a power supply that provide the right voltage and amperage, and you can test that with USB Charger doctor […]
Hardkernel ODROID-XU4Q is a Fanless Version of ODROID-XU4 Exynos 5422 Development Board
[Update May 2018: You may be interested in ODROID-XU4Q review with Ubuntu 18.04] We had already seen ODROID-XU4 development board price drop to $59 earlier this year, but a frequent complain about the board remained: it requires a fan to operate at full speed, and makes noise while the fan turns. To address this issue, the company has now launched ODROID-XU4Q board with exactly the same specifications with Samsung Exynos 5422 octa-core processor, 2GB RAM, eMMC module support, Gigabit Ethernet, USB 3.0, HDMI 1.4 etc…, except the fan is replaced by a large heatsink. The company has also thoroughly tested both versions in different configurations such as setting the maximum frequency to 1.8 or 2.0 GHz, and found ODROID-XU4Q to be slightly slower under high load due to CPU throttling, as the large heatsink does not cool quite as well as the smaller heatsink in combination with a fan. However […]
Intrinsyc Introduces Open-Q 2100 SoM and Devkit Powered by Qualcomm Snapdragon Wear 2100 SoC for Wearables
Qualcomm unveiled Snapdragon Wear 2100 SoC for wearables early last year, and since then a few smartwatches powered by the processor – such as LG Watch Style and Watch Sport – have been launched, and Intrinsyc has now unveiled one of the first module based on the processor with Open-Q 2100 system-on-module, and a corresponding Nano-ITX baseboard. Open-Q 2100 SoM specifications: SoC – Qualcomm Snapdragon Wear 2100 (APQ8009W) quad core ARM Cortex A7 processor @ up to 1.094 GHz with Adreno 304 GPU System Memory – 512 MB LPDDR3 Storage – 4GB eMMC flash Connectivity – 802.11 b/g/n WiFi (WCN2320), Bluetooth 4.1 LE, Gen 8C GNSS (GPS/GLONASS) with on-board u.FL connector (WGR7640) Audio – Integrated Codec/PMIC (PM8916-1) with optional support for Fluence HD, Snapdragon Voice Activation, and Snapdragon Voice+ 2x 100-pin board-to-board connectors with USB 2.0, I2S, GPIO, MIPI DSI up to 720p @ 60 Hz, 2-lane MIPI CSI, SDC2/microSD […]
AIO Robotics Zeus 3D Printer, Scanner, and Editor Allows You to Print and Copy 3D Objects Without a PC
The 3D printer maket is brutal. Many people have tried to designed their own 3D printer, and launch them through crowdfunding campaigns, but the rate is failure is very high, and some cases, scams are also reported. When I covered BlackSmith Genesis 3D Printer, Scanner and Copier in 2015, I was hopeful it would become successful, as it solves one the main problem with 3D printing: the high skill sets required to operate the device as it would just operate as a 3D copier. Place the object inside the 3D printer, press copy, and a few minutes or hours later, you get a copy of the object without having to learn about 3D design or G-code format. But today, I noticed the website account at expired, and the 3D copier was nowhere to be found, so it looks like another failure. Around the same time in 2015, another company called […]
