How To: Make a Totally Geeky LED Pocket Watch That Tells Time in Colors

The cell phone may have replaced the pocket watch, but thanks to some clever mods and hacks, "old-fashioned" time telling is making a comeback. Smart watches that connect to your mobile device cannot only tell you what time it is, but also change the song you're listening to and let you know how many Facebook notifications are waiting for you. Frank Zhao, an electrical engineering student at the University of Waterloo, decided to do something a little different with his LED pocket watch. It h...

How To: Turn Any Wall Portrait into Your Own Personal Scooby Dooish "Eye" Spy Surveillance System

Remember how the bad guys in Scooby Doo would always use cut-out portraits to spy on people through walls? Well, unless your landlord is super cool, you probably shouldn't start cutting holes in your wall just yet, but you can make a higher tech version, thanks to NASA employee Mark Rober. Mark used a cheap picture frame and a portrait with the eyes cut out to make the "Scoob Cam," which also doubles as a surveillance device. He used an iPhone and an iPad to start a FaceTime chat, then taped ...

How To: Turn Your Old NES into an All-In-One Retro Gaming Console

While the PlayStation and Xbox models may rule the current world of gaming, there are still those who love to keep it old school. The grittiness, toughness and nostalgia that is laced throughout old gaming consoles appeals to many people.

In the video below, Becky Stern from Adafruit uses a kit with a replacement glass back, tweezers, screwdrivers, and ...

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: Light Up Your Whole House with This DIY 'Nuclear Explosion' Chandelier

If you're the kind of person who misses the bright, sunny days of summer during the colder months, Michail has the perfect addition to your home. He built this "Nuclear Explosion" Chandelier that's as bright as daylight, so you can recreate the feeling of summer, no matter what time of year it is. It puts out 99,400 lumen (a typical 60W light bulb only produces 800 lm), so it takes quite a bit of electricity to run. Michail used 7 metal-halide lamps, which are much brighter and more energy ef...

How To: Add an Extra USB Port to Your Wired Computer Mouse

Ever try plugging in two flash drives into your MacBook Pro before? The USB ports on MacBooks are not only directly side by side, they're insanely close to each other, so it can be extremely difficult to plug in a large USB device with another smaller USB device. Sometimes it can fit, but it's a strain on the USB port and the device itself. If one of the items in question is a USB mouse, then your worries are over...

How To: This DIY Illuminated Isomorphic Keyboard Changes Colors as You Play Music

An isomorphic (or self-transposing) keyboard is "a musical device where a grid of notes is displayed to the user and the interval change between notes in constant for any given direction." For those of you who didn't grow up playing the piano like I did, that basically means that it lets you move between keys easily without having to learn new patterns because the keys are laid out so that a chord is the same pattern in every musical key.

How To: This DIY Xbox LIVE Traffic Light Tells You When Your Friends Are Gaming

Games are always more fun when you have someone to play them with, but if you're not always logged in to your Xbox LIVE account, how do you know when your friends are online? You can always log in and check, but where's the fun in that when you can hack together a traffic light to do it for you? Andrew F hooked up an Arduino with an Ethernet shield to check every five minutes to see how many of his Xbox LIVE friends are online. For each friend, it records either a zero or a one, depending on ...

How To: Use Your "Dead" Car Battery to Power Emergency Fans, Lighting, and More!

A common misconception is that all car batteries die. This, in fact, isn't true—the majority of "dead" car batteries just don't contain enough juice to power a car, but they can still provide enough watts to keep emergency fans and lighting running, which is great when a power outage occurs. So, instead of lugging the battery to the nearest drop-off center or just letting it collect dust in the garage, you can put that car battery to good use.
