How To: Unroot & Revert Your OnePlus 5 or 5T to 100% Stock

To please those of us who love to mod and root our Androids, OnePlus has made both the OnePlus 5 and 5T relatively easy to customize — so much so that the 5T topped our list for the best phones for rooting. Unfortunately, unlocking the bootloader and using root to modify the firmware on your OnePlus 5 or 5T makes it hard to update to a new firmware such as Oreo when compared to stock.

How To: Everything You Can Do with the Camera Control Button on Your iPhone 16 or 16 Pro

The devices in the new iPhone 16 series lineup have one feature no other iPhone models have: a physical Camera Control button.

How To: Adjust Your Samsung Galaxy Note's S-Pen Sensitivity for Better Touch Response

Touchscreens are all the rage these days, and it seems that the stylus has become a relic of the past thanks to newer and better fingertip responsive smartphone displays. But when it comes to phablets like Samsung's Galaxy Note line, the added S-Pen is definitely helpful for more accurate and precise actions (and a less greasy screen). Of course, there are disadvantages of using an S-Pen too, one being hardware issues. Unlike your finger, the S-Pen can malfunction and become a huge problem, n...

How To: Rotate Wallpapers on Your iPhone to Photo Shuffle All Your Favorite Pics by Tap, Lock, Hour, or Day

Your iPhone has plenty of already-created Apple wallpapers just waiting for you to set as your Lock Screen and Home Screen backgrounds.

How To: Sideload Apps on Chromecast with Google TV — Get Virtually Any Android App on the Big Screen

At launch, Chromecast with Google TV is fairly limited in the number of compatible apps. Many of the usual suspects are there, but there are some interesting omissions, like Google Stadia (though support is coming).

How To: Unlock Apple's 'Dark Mode' in iOS 11, 12 & 13 for iPhone

Apple gave us the ability to invert colors on the screen a very long time ago. Then they gave us grayscale mode in iOS 8, Night Shift in iOS 9, and the red screen filter in iOS 10.

How To: Boot Your OnePlus 5 or 5T into Recovery & Fastboot Mode

Both the OnePlus 5 and 5T have two pre-boot menus that every owner should know about: Recovery mode and bootloader mode. The recovery screen lets you wipe cache, perform a factory reset, or install firmware, which can help save the phone from a soft-brick. Bootloader mode, on the other hand, lets you send Fastboot commands via PC or Mac to lock or unlock your bootloader or flash images.

How To: Make the Platonic Solids Out of Playing Cards

Computer Science Professor Francesco De Comité has a fantastic gallery of mathematical images on Flickr. As part of this collection, he has a few hundred images of real or rendered polyhedra made out of paper or playing cards which he calls "slide togethers." These are constructed by making cuts and then sliding one component into the other, creating a shape without using any glue. He constructed the entire set of the platonic solids—the cards form their edges—which can be seen in the image b...

How To: Purify Urine for Drinking with an Emergency Solar Still

It’s called Urophagia—the art of consuming urine. There could be any number of reasons for having the desire to drink your own urine (or somebody else’s). There’s the so-called term “urine therapy,” which uses human urine as an alternative medicine. In urine therapy, or uropathy, it’s used therapeutically for various health, healing, and cosmetic purposes. There’s also those people who drink urine as sexual stimulation, where they want to share every part of each other. And then there’s the o...

How To: Cut a Cooked Steak the Right Way

There is no greater food to master than steak.

How To: Customize the App Icons on Your iPhone's Home Screen

The most significant customization aspect of the iPhone is most definitely the home screen.

Now, there are great customizability options to give you a real personalized touch, and that includes app icons.

How To: iOS 16 Has a Hidden Unit Converter for Temperatures, Time Zones, Distance, and Other Measurements

Fans of "The Hitchhiker's Guide to the Galaxy" will remember the Babel fish, the universal translator you put in your ear so you can understand every language you hear.

How To: Set Up Contact Key Verification for the Highest Level of iMessage Security

Your iPhone is fairly secure by default, but Apple's Lockdown Mode takes it to Fort Knox levels of protection. If you're a high-value target for spyware, phishing attempts, and other sophisticated cyberattacks, it's an essential feature. But for almost everyone else, it's an extreme move. If you simply want to verify someone's identity when chatting, Contact Key Verification is a more practical option.

Apple has changed up quite a few things regarding notifications in iOS 11.

In the process, they've also included another handy feature — the ability to hide certain app notifications from appearing in that History list.

Safari is an excellent app for all your web browsing needs, but Apple gives you the freedom to choose a different default web browser on your iPhone to open links in.

Steampunk Spray Painting: How to Make Almost Anything Look Like Metal

What I'm going to do in this tutorial is, as the title implies, teach you how to make nearly anything look like metal. This can especially come in handy in Steampunk, as most of us don't have the ability to machine brass. We do, however, have access to wood, PVC, and spray paint. Not to mention that, as a costumer, I can speak from personal experience when I say that things made of brass are really, really, really heavy!

How To: 10 Ways to Whiten Clothes Without Using Any Bleach

Whites are the hardest color to keep looking bright and new after just a few months' time.

News: Why Nikola Tesla's Wireless Power Was Fated to Fail Due to Exploding Airships

Francis Bacon, a 16th century philosopher and scientist, caught pneumonia and died because he was trying to stuff snow into a dead chicken. Marie Curie died as a result of her long-term exposure to radioactivity, and her papers from the 1890s are too radioactive to touch without protective gear to this day.
