Best Bluetooth Sports And Fitness Earphones and Headphones 2019

If there was just one thing you could take to the gym with you, I'm pretty sure it'd be a good set of earphones. Whether that's to block out the person grunting on the squat rack next to you, or just to help distract you from the torment of going for a long run, they're definitely a fitness essential in my eyes.Sports Bluetooth Headset price

But with so many available now, how can you know which are the best type to train in? Well, wireless earphones are usually the best for any type of exercise, but still, there are literally thousands of these on the market now all promising different things, so knowing which are any good before you buy isn't easy.

Well, I've tried a bunch of the biggest headphone and earphone brands out there right now to answer this very quandary, and so here are some of the best money can buy, whether it's for running, cycling, working out in the gym or simply chilling out after.
By far my favorite pair of headphones - possibly ever - is the Earin M-2. These are easily the most subtle and slimline in-ear buds I've ever used or seen. And while that's their main sell, they are also super confortable due to their remarkable light weight, and the sound quality is just top notch. They also feel like they are noise-canceling, despite not having this technology bult in, mainly because of how far and snugly they fit into your eardrums.

They aren't waterproof, but they are beautifully designed, come in a super slick charging case that is the same size as a lipstick, and generally just a pleasure to use. A* for the M-2s!

The Best Portable Chargers and Power Banks for 2019

Watching your phone or tablet steadily run out of juice when you're nowhere near a power outlet is stressful. Fortunately, there's no shortage of third-party backup batteries, and they come in every size, capacity, and price range to keep your device going when your battery icon starts to dip in the red. And it doesn't end there. Some power banks are equipped with features like fast charging, wireless charging, built-in cables, AC adapters, LED flashlights—even the ability to jump-start your car.Mobile Power Bank low price

With so many options to choose from, how do you know which power bank is right for you? Read on for the most important points to consider.

Size and Capacity
Generally speaking, the bigger the battery, the higher the capacity and quantity of ports you get. Power banks that fit comfortably in your pocket are typically good for a full phone charge or two, while anything designed to keep you going all day is going to require a bag or a purse.On the pocket-friendly front, most smaller batteries that maximize portability have a capacity of 3,500mAh and under, which gives you just enough charge to top up most phones once.

Once you get above 3,500mAh, battery size increases to the point where it's less likely to fit into your skinny jeans, but can still be stowed in a jacket pocket. There are even batteries that let you power laptops, and have enough juice to charge the average phone 10 times. Of course, they're some of the biggest and heaviest of the bunch, and definitely need to be carried in a bag.
Input and Output Ports
The type of port (or ports) a battery has determines not only whether it is compatible with the devices you want to charge, but also charging speed. At a minimum, most battery packs will have a standard micro USB port for input and a USB-A port for output. But with more phones, tablets, and laptops adopting the USB-C standard, you'll often find a USB-C port in addition to USB-A.

USB-C generally allows you to charge faster, consolidates input/output to one port, and can be found in many new phones. Now, you do have to be careful, because while some power banks have USB-C input, they don't have USB-C output.Lightning is a proprietary Apple technology, so companies need to pay Apple when they use it; that makes it a bit less common to find.

Samsung Shows Off Latest Verizon 5G Home Modems

At Mobile World Congress here today, Samsung Networks showed off what may be the final version of Verizon's home 5G equipment. The company's gigabit home Internet service will debut in Sacramento later this year; Verizon has promised a fixed-wireless 5G service for homes in "three to five cities" in 2018.Industrial gsm gprs modem

Last year, we saw an early form of the 5G home equipment (and in fact gave it a Best of MWC award), but it's changed a lot in the past year. Formerly a big black slab that looked like a cable box, it has now become a vertically oriented white box about the size of a hardback book, with an Ethernet port on the back. It sits in your window, receives a 5G signal, and then distributes it as Wi-Fi in your home.

Running in Samsung's booth, the white "consumer premise equipment" (CPE) was quiet, but hot. The only status indicators on the device are four green LEDs recessed into the area where the ports go.

Samsung also showed off the 5G millimeter wave cell site that will serve Verizon's 5G neighborhood, and the external modem unit that will serve homes where Verizon's millimeter-wave spectrum can't make it into the windows.

All of the system's components are, thankfully, a lot smaller and less obtrusive than we expected. 5G cell sites will be able to sit in "shrouds" on light poles, and are about the size of a backpack. That's important, because they'll have to be placed every 500 to 1,000 feet as the fast, millimeter-wave signal doesn't have much range. The external, weatherproofed antenna unit for the outside of a house is more like the size of a coffee table book. It's all a heck of a lot less imposing than a satellite dish.

WiFi firmware bug affects laptops, smartphones, routers, gaming devices

Details have been published today about a vulnerability affecting the firmware of a popular WiFi chipset deployed in a wide range of devices, such as laptops, smartphones, gaming rigs, routers, and Internet of Things (IoT) devices.WIFI GPS Router

Discovered by Embedi researcher Denis Selianin, the vulnerability impacts the firmware of Marvell Avastar 88W8897, one of the most popular WiFi chipsets on the market, currently deployed with devices such as Sony PlayStation 4, Xbox One, Microsoft Surface laptops, Samsung Chromebooks, Samsung Galaxy J1 smartphones, and Valve SteamLink cast devices, just to name a few.

In a report published today, Selianin described how someone could exploit the Avastar firmware (based on a custom implementation of the ThreadX real-time operating system) to execute malicious code without any user interaction.

"I've managed to identify ~4 total memory corruption issues in some parts of the firmware," said Selianin. "One of the discovered vulnerabilities was a special case of ThreadX block pool overflow. This vulnerability can be triggered without user interaction during the scanning for available networks."

The researcher says the firmware function to scan for new WiFi networks launches automatically every five minutes, making exploitation trivial. All an attacker has to do is send malformed WiFi packets to any device with a Marvell Avastar WiFi chipset and wait until the function launches, to execute malicious code and take over the device.

"That's why this bug is so cool and provides an opportunity to exploit devices literally with zero-click interaction at any state of wireless connection (even when a device isn't connected to any network)," Selianin said.

Convert ATX PSU to Bench Supply

The standard computer power supply unit (PSU) turns the incoming 110V or 220VAC (alternating current) into various DC (direct current) output voltages suitable for powering the computer’s internal components and with a little bit of imagination it is possible to convert ATX PSU to a bench mixed Signal connector .

atx psu
Most computer PSU’s range from about 150W up to 500W so there is plenty of power. The original ATX standard connector used for powering the motherboard was a single 20-pin Molex that has all the required +12VDC and +5VDC voltages with huge output currents and short circuit protection as well as a Power-ON wire that allows the PC’s software to turn “OFF” the PSU on shut down.

Firstly and more importantly before you start to convert ATX PSU, make sure that the PSU is unplugged from the mains supply and discharged by letting it sit unconnected for several minutes before you start. This is important! as it could result in a potentially dangerous or even lethal situation due to the high voltages inside the PSU if you decide to dismantle it. Also make sure that the metal box of the PSU is correctly earthed or grounded. You are responsible for your own safety!.
We can not just simply plug the PSU into the mains supply and expect to get the required 5 or 12 volts output. The standard PC power supply unit has two safety mechanisms that prevent it from being switched “ON” without the motherboard attached.

There are several different coloured wires attached to the 20-pin ATX connector providing several different voltage outputs such as +3.3V, +5V, +12V, -12V, -5V as well as a number of black ground wires and a couple signal wires as shown in the following image along with their colour-code and description.

Best Wear OS watch 2019: our list of the top ex-Android Wear smartwatches

The Fossil Sport is now our favorite Wear OS watch that you can buy. Read on below to see why it's now ranked in top place.best 3G Smart Watch

Google's Android Wear had a shaky start, but it's now an increasingly mature platform thanks to the Android Wear 2.0 update and the switchover to the Wear OS name in early 2018.

Android Wear may be over, but Wear OS is now better than the former ever was thanks to updates to improve navigation, battery life and more on the platform. This list has changed a lot since we first ranked the best Android Wear watches.

One of the main reasons Google renamed its operating system is to make the watches more palatable to those who own an iPhone. Wear OS watches work with both Android and iPhones, but it's worth checking compatibility before you buy as each watch will only work with certain devices.

What is the difference between a shielded and unshielded modular coupler?

A Shielded Coupler is encased in a metal structure allowing it to ground to a metal wall plate or panel; an Unshielded Coupler is not.rj45 unshielded connector

A shielded coupler would be required when using a shielded cable terminated with a shielded plug. The shielded plug would tie the shield to the coupler, thus grounding it as well as passing it on to the shielded cable assembly plugged into the other side of the coupler. Because of this, a shielded coupler is only required if you are using shielded cable assemblies.

If the cable assemblies you are using do not have shielded plugs then you do not need a shielded coupler.These products are primarily used in the networking, telecommunications, computing, military, aerospace, transportation and broadcasting industries. Bel's product groups include Magnetic Solutions (integrated connector modules, power transformers, power inductors and discrete components), Power Solutions and Protection (front-end, board-mount and industrial power products, module products and circuit protection), and Connectivity Solutions (expanded beam fiber optic, copper-based, RF and RJ connectors and cable assemblies). The Company operates facilities around the world.
