Here’s a look at four ways smartphone electrocution can occur and how to make sure it doesn’t happen to you. Don’t Charge and Use Your Cellphone While in Water In December 2016, a 32-year-old British man was found dead in the bathtub. The cause was a charging smartphone. He was resting a charging iPhone on his chest when the device made contact with the water. His injuries were severe, including burns on his chest, arms, and hand....

Besides donating or recycling, another popular option is to sell your used electronics for money, something you can do right at home or work, usually without fees. To sell used electronics online, you have to answer some questions to value the items, print off a free shipping label, package the products in a box that you or the company provides, and then send it off. Once they receive the items and verify that the condition is as you described, it’s common for them to pay you via a check, PayPal, gift card, or some other means just a few days later....

What’s Taking up So Much Space on My PC? One of the simplest places to look for items taking up a lot of space on your PC is the Recycle Bin. The Recycle Bin is where your deleted files go. Files aren’t automatically deleted. Instead, they are marked for deletion and placed in the Recycle Bin. That gives you some time to restore the files if you have mistakenly deleted one, but it can take up a lot of space....

Sadly, it’s become increasingly common to advertise that a registry or other PC cleaner program is free to “download” even though the all-important “cleaning” part will cost you.

Researchers at MIT have designed a modular chip that uses flashes of light to convey information between its components. One of the design goals of the chip is to enable people to swap in new or improved functionality instead of replacing the whole chip, in essence paving the way for perpetually upgradeable devices. “The general direction of reusing hardware is a blessed one,” Dr. Eyal Cohen, CEO and co-founder of CogniFiber, told Lifewire over email....

The Trouble With USB and Older Head Units While USB seems like just another type of auxiliary input, there’s actually more going on under the hood than a lot of people realize. Normal auxiliary inputs require an analog signal from a device like a satellite radio, CD player or MP3 player, which is fine, but USB allows a device to offload digital audio data to a head unit and allow it to do the heavy lifting....

According to Apple rumormonger Mark Gurman, Apple is working on not one, not two, but several new monitors. After a years-long drought in the Apple displays department, this kind of revelation gets the imagination going. One of these will be an update to the current high-end 32-inch Pro Display XDR, but other than that, we can only speculate. So, speculate we shall! “It’s possible that Apple may incorporate some of the technologies it has developed for its iPhone and other devices into its new external monitors with Apple Silicon....

The iPad Air 4 received a major facelift compared to the previous generation, but the new aesthetic is hardly the biggest change here. Equipped with the powerful A14 Bionic processor, a beautiful and fully-laminated Liquid Retina display, and a magnetic Magic Connector that works with accessories like the second-generation Apple Pencil and the fantastic Magic Keyboard, Apple has quietly built a solid competitor for the iPad Pro at a lower price point....

Ohm’s Law Ohm’s law is the relationship between voltage, current, and resistance in a circuit. It is the most common (and most simple) formula used in electronics. Ohm’s law can be written in several ways, all of which are commonly used. The current flowing through a resistance is equal to the voltage across the resistance divided by the resistance (I=V/R).Voltage is equal to the current flowing through a resistor times its resistance (V=IR)....

Overall Findings Block heaters are useful in very cold situations, as they help to warm the engine prior to starting it. This helps reduce damage caused by starting an engine in freezing temperatures. Remote starters, on the other hand, simply start the engine from a distance, allowing you to wait from a warm environment as the car interior warms up. Use Cases: Engine Maintenance vs. Remote Convenience Block heaters are electric heating elements that prevent engine coolant from gelling....

How to Use a Car Cassette Tape Adapter Cassette tape adapters allow you to play external audio devices—including CD players, smartphones, and MP3 players—from any vehicle’s tape deck head unit. They are shaped like compact cassettes on the outside, but the internal workings are quite different. While compact cassettes hold two connected spools of magnetic tape for audio, car cassette adapters contain magnetic inductors that fool tape decks into thinking they are cassettes....

When run from outside Windows, you can use this program to destroy a hard drive that has any operating system installed to it. From within Windows, this free tool can completely erase any internal or external drive other than the one you’re using for Windows, which is usually the C: drive. More About CBL Data Shredder CBL Data Shredder comes in two versions, both of which are useful for different scenarios....

While modern networks only loosely follow the conventions laid out by the OSI model, enough parallels exist to be useful. What Are Some Helpful Memory Aids for the OSI Model Layers? Students learning networking often have difficulty memorizing the name of each layer of the OSI network model in the correct order. OSI mnemonics are sentences in which each word starts with the same letter as the corresponding OSI model layer....

Dell calls them the “world’s first video conferencing monitors certified for Microsoft Teams,” but there’s an even more important point here. Big manufacturers are making it much easier to work from home, and to stay connected. And with an all-in-one solution like this, you no longer need to call the IT department to help set it all up. Home + Work More of us work from home than ever before thanks to the pandemic, and we might stay that way afterwards....

While we often think of Disney movies as the ultimate family-friendly content, some older classics feature racist stereotypes and inaccurate depictions of people. Instead of erasing the content, the media company has added an advisory before these films on its Disney+ streaming platform to acknowledge the problematic scenes and encourage viewers to read more about a new initiative dedicated to better representing its audience. Choosing to show these scenes with commentary—as opposed to erasing them or showing them without any mention of their problematic nature—is an “important step” for Disney to reckon with its own film library, as well as the country’s reckoning of the past, Darnell Hunt, UCLA’s Dean of Social Sciences, told Lifewire in a phone interview....

What Is an EMZ File? A file with the EMZ file extension is a compressed image file, more specifically referred to as a Windows Compressed Enhanced Metafile file. These types of files are actually just GZIP compressed EMF files, which is a graphics format used by Microsoft applications like Visio, Word, and PowerPoint. How to Open an EMZ File The free XnView MP program can view EMZ files on Windows, Mac, and Linux....

How Big Is It? If you want measurements, the Power Bar is about 2.75 inches (7 cm) wide, 7.25 inches (18.5 cm) long, and a little over 1 inch (3 cm) thick. It’s good for a bag and can sit on or inside of a desk, but it’s way less portable than a lot of other charging solutions, especially when you factor in the cords and adapters you might also need to bring along....

We haven’t even gotten into the weeds here, and already let’s recap. There are free (likely level 2) chargers on public land in North Carolina that add maybe a few miles every hour to an EV. They’re probably at parks, rest stops, and other areas where people congregate with vehicles. Moss is so angry at this scenario; he would rather destroy these stations with up to $50,000 than let some people charge their vehicles....

When it comes to sound quality, a good smart speaker should have exceptional voice recognition and music playback, so far-field microphones are just as important as tweeters and woofers. The far-field microphones must be able to hear your voice commands in the face of background noises, and you shouldn’t have to shout to get the speaker to pick up your voice commands from a distance. Audio software is also important, and more and more speakers are incorporating features like adaptive audio, which allow your smart speaker to adjust to the acoustic conditions of the room....
