Giveaway Week – MINIX NEO P2 100W USB-C Charger

MINIX NEO P2 is a 100W Turbo 4-Port GaN Charger with two USB-C ports, two USB-A ports with support for USB PD 3.0, and Qualcomm Quick Charge 3.0. I’ve been using for recent reviews of NanoPI R2S & NEO3, as well as Raspberry Pi 400, and I really like it as it saves me a lot of space, I don’t have to worry about undervoltage, and I can power up to four boards from a single power supply. MINIX sent me two samples. I’ll keep one for me, and sent the unopened one to one of CNX Software readers. To enter the draw simply leave a comment with your country and whatever else you’d like to say. If the country is missing, I’ll consider the entry void. Other rules are as follows: Only one entry per contest. I will filter out entries with the same IP and/or email address. Contests […]

MINIX Unveils USB-C Hub with 960GB SSD, 100W USB Charger

MINIX USB-C Hub with 480GB SSD, 100W USB Charger

MINIX, the Hong Kong company, is well-known for its Android media hubs and Windows 10 mini PC‘s but in recent years they’ve started designing accessories for Windows & Mac computers and laptops. In the past, we’ve checked out MINIX NEO C Plus USB-C Adapter, an M.2 SSD card pre-loaded Windows 10 Pro for N42C-4 Mini PC, and another USB-C hub with integrated 120 or 240GB SSD. The company has now unveiled four new accessories with three USB-C hubs, including one with a 480GB or 960GB SSD, and one compact 100W USB charger using the latest Gallium Nitride (GaN) technology. This morning, I received two pairs of USB-C hubs with different colors and two 100W USB chargers. The model I did not get – MINIX NEO Storage Pro – is specifically made for Apple MacBook Air and MacBook Pro with built-in SSD storage, HDMI 2.0 up to 4K @ 60 Hz, […]

GuRu Launches Desk-Range Wireless Power Transfer Evaluation Kit

Several companies are developing wireless power at-a-distance solutions with various ranges, from desk power/charging to factory sensor power, including Energous and TransferFi. CNX Software has been contacted by another company working in the field with Guru Inc launching the GuRu mini evaluation kit capable of wireless power transmitting several watts within a desk using a 24 GHz chip. There are very few details about the internals of the transmitter and receiver, but the company told CNX Software GuRu developed its own 24GHz chip built in a standard CMOS process. The chip is said to use “Smart RF Lensing power transfer, enabled via highly focused, intelligently-controlled millimeter waves” in order to increase both power transfer and range by up to 10 times, as well as deliver smaller and cheaper devices. The (G3100-005-EVK) wireless power transfer evaluation kit is comprised of the following components/accessories: A generator unit (GU) suitable for desktop environment […]

Compact Wind Turbine Generates Up to 800 Watts, Outputs 12V or 24V DC

If I had to install some equipment at home were the mains are not easily accessible or would result in long cables, I’d immediately think about issuing solar panels to charge a battery, and discard the idea of using a wind turbine since in my mind those are really large and need to be fitted to a tall pole to be effective. But I’ve recently come across a relatively compact wind turbine that generates up to 800 Watts and outputs 12V to 24V DC. Key features and specifications: Rated Power – 800W Voltage 12V/24V Generator – 3phase AC PMG Rated wind speed – 11.5m/s Safe wind speed – 55m/s Wind direction auto adjustment Number of blades – 3 to 6 Windwheel diameter – 1.35m Material – High-strength PA66 and fiber-reinforced nylon Temperature Range – -40℃-80℃ Those are the specifications for the model I found on Banggood ($295.99), and I have […]

ZS1100A IoT Power Meter Supports Sigrok Open-Source Software (Crowdfunding)

A few months ago, I tested Qoitech Otii Arc power meter & DAQ system designed for developers of IoT devices, and fount out it would be incredibly useful to developers of battery-operated devices since it shows voltage and current graphs synchronized with the serial output making it easy to see where software might be optimized. The system can also capture analog and digital signals from the DUT and emulate batteries with user-defined characteristics. But this weekend, I’ve come across a very similar solution with ZS1100A IoT power meter that also happens to be compatible with Sigrok open-source signal analysis software, and the corresponding Pulseview GUI. ZS1100A IoT power meter specifications: Measurements Output Voltage Range – 0 to 6 V programmable in 10 mV steps with +/- 5mV accuracy, Current Measurement Range – -0.5 A to 1.5 A (linear range) with < 0.1 μA resolution, accuracy of 1% of measured value […]

Bluetooth USB PD Tester Connects to Windows and Android/iOS Apps for Data Logging

We’ve written about USB-C PD power meters in the past such as Satechi USB Type-C power meter. Those allow you to measure (charging) voltage and current displayed on the screen part of the meter. But thanks to Bluetooth and USB connectivity, Riden TC66C USB PD tester allows you to capture and log data over a period of time by connecting to a Windows program or Android/iOS mobile app. There’s also a version without Bluetooth – TC66 – that only works with the Windows program over USB. Riden TC66C/TC66 Bluetooth USB PD tester specifications: Display 0.96″ color IPS display with 160×80 resolution Auto screen off time – Adjustable up to 9 minutes Measurements Voltage Range – 0.005V-30V +/- 0.1mV; accuracy: ±(0.5%+10digits at 23℃) Current Range – 0 to 5A +/- 0.01mA; accuracy: ±(1%+20 digits, at 23℃) Power Range – 0-150W Temperature Range – 0 to 80°C Load impedance range – 1Ω to 9999.9Ω Charge […]

ATX12VO Standard Reduces Idle Desktop Power of ATX Motherboards

I remember a few years back when I still used an AMD FX8350 power tower PC power consumption was about 75 Watts at idle, and around 15-20 Watts when the computer was turned off. Those are really high numbers especially considering many systems can now run under full-load for up to 15-20 Watts. Power consumption has vastly improved since, but desktop computers are still not the most efficient even while idled or power off, so a new standard has been created. ATX12VO single rail power supply desktop platform form factor takes out the 3.3- and 5-volt rails from the power supply and relies on the motherboard instead that can handle those voltages more efficiently. The name makes sense as ATX12VO should read as ATX 12 Volts Only. The new motherboard standard was at least partially designed to meet the requirements of upcoming new energy regulations for desktop computers in the […]

Power Sensors and Boards with Water using 5V/12V Micro Water Turbines

I follow some online IoT groups, and many of the projects are related to smart farming and greenhouses. People may want to monitor temperature and humidity and other environmental factors using battery-powered sensors. If there are many of those sensors, this can be cumbersome to either replace or recharge batteries, and that increases maintenance costs. But since plants usually need to be watered there should be some water pipes around, and I’ve just found out some low-cost micro water turbines that can generate 5V or 12V when connected to a water pipe and water flows. Micro water turbines specifications: Output Voltage 5V model 5 +/- 0.3 VDC water flow 10+ L / min 3 to 5 +/- 0.3 VDC Water flow 4L / min 3 +/- 0.25 VDC Water flow 3.5L / min 12V model 12 +/- 0.3 VDC water flow 10+ L / min 5 ～ 12 +/- 0.3 […]
