How To: Get Around Apple's Expensive Lightning Adapters

Lightning has struck, but not everyone is excited. Apple's new 8-pin Lightning connector for the iPhone 5 has replaced the aging 30-pin connector.

How To: Deter Data Thieves from Stealing Your Flash Drive by Disguising It as a Broken USB Cable

Having a flash drive is more or less a must, but the biggest downside is that they often get stolen, and it's not hard to figure out why. They're small, so they easily fit into pockets, and a lot of people store valuable information on them. Want to pretty much guarantee no one takes yours? Disguise it as a broken USB cable like Windell Oskay of Evil Mad Science Labs so it just looks like a piece of junk to would-be thieves. The materials are pretty simple: a flash drive (the smaller the bett...

The iPhone 5 will be here in no time. Pre-orders started at 12:01AM PST this morning and it's expected to start shipping in about two weeks. Verizon, AT&T, and Sprint are all handling unlimited data plans differently, so if you currently have an unlimited plan and are going to get the iPhone 5, you'll want to know what your carrier is doing before you upgrade so you don't end up with a very unpleasant surprise on your next phone bill.

How To: Upgrading to iOS 6? Try It Out Now Before the Official Release Date

Apple announced earlier this week that the official release date for iOS 6 will be September 19, but why wait when you can get it now? The Gold Master developer version was made available on Wednesday, and it's the same file as the final version that's going to be released to users on the 19th. Anyone can download it, so if you want to avoid being part of the frenzy on Wednesday when everyone else is trying to get it too, it may not be a bad idea to get a head start. A quick note: If you inst...

How To: Customize Your Chrome Extensions for Specific Websites with Extension Automation

Browser extensions help us do all sorts of things, and there's one for just about everything, but like anything else, they can be easy to get carried away with. If you use a lot of add-ons, your browser is probably running some of them in the background on sites that don't actually use them for anything. You can disable them, but it's a pain to change your settings all the time, which is where Extension Automation comes in. Extension Automation is (ironically) a Chrome extension that lets you...

How To: Getting a New iPhone 5? Check Out These 11 Cool and Practical Uses for Your Old iPhone

The new iPhone 5 was just revealed yesterday, and it's 18 percent thinner and just 1/5 the weight of its 4S predecessor. It's also taller with a larger screen, which gives you a fifth row for apps now. As far as speed is concerned, it has a speedy A6 chip and can tap into wireless 4G LTE networks for fast Internet. Both the iSight and front-facing FaceTime cameras were improved, too. The only downside seems to be the tinier "Lightning" connector, which replaces the standard 30-pin connector w...

How To: Trick Your Twitter Followers into Thinking You're Somewhere Besides Where You Really Are

There are plenty of reasons not to use location information when you tweet, whether you're trying to stay safe or just don't want your crazy ex showing up while you're in line at the grocery store.

How To: Moving Soon? This DIY Alarm Will Make Sure Your Stuff Stays Safe in the Truck Overnight

The worst part of moving into a new place is, well...moving. It's tedious, a lot of hard labor, and it can take forever, and don't even get me started on all those labels. It's also one of the only times in your life when everything you own can be stolen at once, since it's sitting in a movable container. Rather than risk losing everything, try this DIY Moving Truck Alarm System by Tim Flint that lets you know when the loading door is opened so you can catch would-be thieves red handed.

How To: Planning on Buying an iPhone 5? Here's How to Get the Most Money for Your Old iPhone 4 or 4S

Apple is notoriously cryptic when it comes to the reveals of its new products, and as usual, they've kept us guessing about the release of the iPhone 5 (or "New iPhone?"). It's expected to be officially revealed on September 12, and rumor has it that sales will begin on the 21st. Though the whole world seems to be anxiously awaiting the announcement, there has also been some controversy surrounding the iPhone 5's production. With the high number of suicides and poor working conditions at Foxc...

How To: Access the Boot Menu and BIOS in Windows 8

One of the most played-up features of Windows 8 is that it's so much faster than previous versions. So fast, in fact, that Microsoft had to change the way that users access the BIOS because 200 milliseconds just isn't enough time to hit the right key. It may take some getting used to, but it's probably a welcome change for most people, considering that the "right" key is different depending on what type of computer you're running the OS on.

How To: Find Out If the FBI Is Keeping Tabs on Your Apple Device (UPDATED)

It's no secret that there's a lot of surveillance going on these days. It's easier than ever to end up in a database, and even former government agents are speaking out about the atrocious amount of spying being done against our own citizens. They've targeted our laptops, cars, IP addresses, and now they're coming for our iPhones. AntiSec hackers managed to get their hands on a list of over 12 million Apple UDIDs (Universal Device IDs) from an FBI computer, and they published 1,000,001 of the...

How To: Build a Cheap Arduino Tachometer to Measure the RPMs of Spinning Fans (And More)

A tachometer, or RPM counter, is a device that measures the speed of something that's rotating. In a car with a manual transmission, the tachometer can be helpful in determining when to release the clutch and how much gas to give when you're taking off. This DIY Arduino Tachometer by Chris on PyroElectro uses an infrared transmitter and receiver break-beam pair to measure the RPM of a computer fan. When the fan blade passes between the transmitter and receiver, the IR beam counts the interrup...

How To: Satisfy Your Need for Speed with This DIY Arcade-Style Racing Cockpit

The pedals, shifters, and steering wheel are laid out to match the measurements in his rea...

DIY Portable Power Pack: Turn Your Backpack into a Solar-Powered Gadget Charger

A smartphone is pretty much useless with a dead battery. When you're out and about, it can be hard to find a place to plug in (if you remembered your charger, that is).

Theodore started with just a normal backpack, some solar panels, 18 gauge wire, and a USB port and hacked it into a traveling solar ch...

How To: Your Guide to Finding Free Creative Commons Images and Other Media Online

Creative Commons is awesome—really. If an image, video, or audio file is tagged with a CC license, that means you can use it as long as you give appropriate credit to the owner. For bloggers with no money for pricey stock media, it's a godsend. When you license your own media under CC, you can choose how you want it to be used by others and whether or not it can be used commercially.

How To: This DIY Baby Monitor Uses Lasers and a Wiimote to Detect Your Child's Breathing

Proud new papa Gjoci wanted to make sure he never had to worry about whether or not his baby girl was breathing, so he built this amazing breath-detecting baby monitor using a Wii remote, a printed circuit, and a laser. First, he opened up the Wiimote and took out the camera, then used an Atmel Atmega88 microcontroller to make a printed circuit. Low-power infrared lasers shine on the baby's clothing and the Wii camera detects the motion of the baby's breath, activating an alarm if the motion ...

How To: Undo Instagram's Photo Filter Magic with Normalize for iPhone

Tired of the Instagram wave? If you're sick of having to view the world through low-contrast and sepia-toned filters, there's a way to get them back to how they're supposed to look, and it's called Normalize, which undoes the magic filtering that Instagram and similar photo filter apps provide. The process of un-Instagramming your (or anyone else's) photos with Normalize is perhaps easier than Instagramming them in the first place. All you need to do is copy and paste them into the app and wa...

How To: Find Out What Personal Data Your Mobile Apps Are Leaking with Mobilescope

If you use apps on your smartphone, chances are you have no idea what those apps are doing with your information. Just this year, there have been several scandals involving apps transmitting user data, like Path uploading users' entire address books onto its servers, HTC's Security Flaw, and Brewster exposing users' personal information (even Ashton Kutcher's). A new service called Mobilescope wants to make sure you always know where—and to whom—your data is going. Lots of apps copy your cont...
