You don't really want to be that douchebag that interrupts a movie or the middle of a lecture with their annoying ringtone just because ...

How To: Restring & Tune an Electric Guitar

Hello again, faithful readers. For today's lesson, we will be learning the correct way to restring and tune an electric guitar. I almost wasn't going to post this because it is so basic. But, as with many basic tasks, there are a lot of people who know how to do it, but can't really do it right. If you are a new guitarist, this is an essential piece of maintenance work, because guitar shops usually charge way too much for this task. Of course, I'm kinda cheap, so even 5 bucks is too much for ...

How To: New YouTube Capture App Lets You Record, Edit, and Upload Videos Easily with Your iPhone

After everyone updated their shiny Apple devices to iOS 6 a few months ago, they were shocked to find that their beloved YouTube app was missing. As it turned out, Apple decided to kick YouTube off their list of pre-installed stock apps. The new YouTube app (found in the iTunes App Store) is definitely better than the native one from iOS 5, but it's lacking a direct upload to YouTube option. Sure, you could upload videos from your iPhone's Camera Roll, but the options are limited as to what y...

How To: Listen to Text Messages and Other Notifications While Driving—Without Touching Your Phone

The car is arguably one of the worst places to receive a text message. You know you can't resist looking, and when you do, your attention is no longer on driving, it's on reading the latest gossip or whatever. You take your eyes of the road for just a few seconds and you could get an expensive ticket, or even worse—an accident. But you can't just ignore that notification sound or vibration, can you? So, if you just have to know what it says right then and there, why not at least do it in a sa...

How To: Hack Your Mini-Fridge into a Vending Machine to Take Care of Freeloading Friends at Your Next Party

It always sounds like a good idea to throw a party... until the party gets there. Next thing you know, you're running around hiding anything breakable, and once everyone leaves, you're stuck cleaning up the mess. But the worst part is footing the bill for everything, and if you don't charge at the door, your chances of getting anyone to chip in are slim to none once the party starts.

How To: Convert Your Old Cassette Tapes into Digital MP3 Music Files

Before my time, people used to listen to music recorded on these things... I didn't really know what this thing was until my parents clarified and told me that they were called cassette tapes. These "cassette tapes" were utilized to store sound recordings on either side of the tape, which could usually hold between 30 to 45 minutes. I laughed at that information as I took out my iPhone 5 (roughly the same size), which can store roughly 40,000 minutes worth of music.

How To: Turn Any Ammo Box into an Awesome Set of Portable Speakers

Believe it or not, an ammo box can still be of use to you once its rounds are gone. You can use it for storage, as a toolbox, or possibly even as a Faraday cage. But if you want to use it as more than just a container, why not turn it into a portable set of speakers that you can take with you anywhere? The ammo can speaker pictured above was made by Instructables user Dustin White. He started with an empty .50 cal box, though you could probably even use thinner 5.56 or 7.62 mm cans. He remove...

How To: Repair or Replace Your Broken Headphone Jacks

If you haven't met a person that's broken a pair of headphones, you might need to get out more. No matter how expensive or cheap a pair of headphones are, the sound can get buggy, the wire can get cut, or the headphone jack itself can be broken or ripped off the cord. But instead of buying a new set of headphones or borrowing the ones from your cousin with the earwax problem, you can easily fix it yourself.

RoboDoc: A Kid-Friendly DIY Robot That Makes Doctor Visits a Little Less Scary

Remember going to the doctor when you were a kid? If the word 'traumatizing' comes to mind, you'll love the RoboDoc by MarkusB, a robotic doctor that makes checkups a little less scary (and a lot more fun) for kids. It all started when Markus took his 14-month-old daughter for a checkup. The finger clip that the doctor used to check her pulse terrified her, so Markus decided to build a heartbeat monitor just for kids that's much more likely to make them laugh than cry.

News: Windows 8 Reports Your Downloads to Microsoft, But Is It Really a Security Threat?

Security researcher Nadim Kobeissi has discovered that the Windows 8 SmartScreen feature, meant to screen downloads for malicious software, actually reports the data about which applications users are installing to Microsoft. He also says that "the Microsoft server is configured to support SSLv2 which is known to be insecure and susceptible to interception." The two main concerns are the ability of law enforcement to subpoena Microsoft for the information and of hackers to intercept user data...

News: Freaking DIY Magma! Syracuse University Creates Recyclable Red-Hot Lava Flows

Believe it or not, it's possible to make your very own lava—if you have a furnace capable of heating up to 1,200 degrees Celsius, that is. Bob Wysocki and Jeff Karson started the Syracuse University Lava Project to study basaltic lava and give students a hands-on way (hypothetically, of course) to learn about it. Oh, and they also want to use it for art projects. Sign me up for that class! It all starts with 1.1 billion-year-old basalt gravel, which apparently anyone can buy. They put the gra...

News: Colloidal Display Turns Soapy Bubbles into a Transparent 3D Projection Screen

We've all played with bubbles as kids, but I think most would agree that they're not exactly the most functional of objects. An international team of researchers made up of Yoichi Ochiai, Alexis Oyama and Keisuke Toyoshima wants to change that. They've figured out how to project both 2D and 3D images onto a micro membrane (soap bubble) using ultrasonic sound waves and a standard projector. The bubble is made of a solution of sugar, glycerin, soap, surfactant, water and milk. The glycerin and ...
