No matter how advanced technology gets, there will always be room for classic video games in the hearts of nerds everywhere. Mini arcades became very popular, as they allowed users to take arcade games on the go. As Game Boys and other mobile gaming devices appeared, the mini arcade slowly disappeared. Well, believe it or not you can combine the best of both worlds! Metku user Japala wanted to make his old Game Boy Advance SP "look cool again," so he turned it into a mini arcade cabinet.
Economists have long since known that people want to be rewarded for taking on risk. Investments are thus judged by their risk-adjusted returns (Sharpe ratios). A typical hedge fund has a Sharpe ratio of around 0.5. This means that its excess annual return over the risk-free rate is about half its annual standard deviation.
There's no shortage of uses for steel wool, but the majority of them tend to be on the pyromaniacal side, like DIY fireworks. This trick by Mike Mikkelson is no different—it uses a homemade reusable "wool cage" to create a spinning vortex of light, like in the photo below. You can do this with just a piece of steel wool on a cable, but Michael wanted something he could easily reuse no matter how many shots he took, so he built a small cage to house the steel wool out of chicken wire, a small ...
Having the ability to decipher any song that plays over the radio or during a commercial is a must for any music-loving fiend. That's what made Shazam so popular.
'Tis the season... for cheap (and free!) video games. THQ's Humble Bundle lets you get 7 games for any price you want, and now they're making it even better by offering fans a free Steam copy of Metro 2033 just for liking Metro on Facebook, which is gearing up for the latest Metro: Last Night release.
Inductive charging has been around since the days of Nikola Tesla, but it has yet to be integrated into a lot of popular devices. This is partially because it's slower and more expensive than methods that involve direct contact.
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...
There are plenty of ways to speed up your wireless network at home, some as simple as changing the placement of your router. While you can always buy equipment to boost your signal, there are plenty of cheap or free DIY solutions you can try as well.
One of the coolest things about chemical reactions is that they can be so unexpected. I mean, who would think you can make water explode?
What do Justin Bieber, Kim Kardashian, Chris Brown, Rihanna, and Soulja Boy all have in common? They suck at Instagram.
What if the Dark Knight used Apple's state-of-the-art Maps application for turn-by-turn driving directions? Well, let's just say you wouldn't want to be in a shopping mall when Batman is in a hurry. Movieclips posted some hilarious parodies of film characters using Apple's new Maps app for directions. Just see what happens when Batman tries to use his iPhone 5 to navigate Gotham on his way to save Rachel in The Dark Knight.
A couple of months ago at the Black Hat security conference, hacker Cody Brocious gave the hotel industry a nasty surprise when he figured out how to hack the locks made by Onity that are used in millions of hotels worldwide.
To say that I am disappointed with the new Maps application in iOS 6 is an understatement. And it seems like the rest of the world is with me, so I needed to find a solution—and quick. Installing the Google Maps web application is a nice quick-fix, but those looking for a beefier navigation solution should check out one of these free map apps.
Want to take advantage of your neighbor's super fast Wi-Fi connection? If they're smart, they probably have it password protected (otherwise you wouldn't be reading this, would you?). But if you have an Android phone, you can get back at them for always parking in your spot and slamming the door when they get home at 2 a.m.—by stealing...er, borrowing, their connection.
Planning on getting the iPhone 5, but want to keep your SIM card? The new nano-SIMs that manufacturers are adopting will be even smaller than the micro-SIMs that most of us currently use. It's fairly easy to cut a regular SIM down to a micro-SIM, but because the nano-SIM will be thinner as well as smaller than the micro, cutting it down to size will require a little more work.

Whether you want to use it to keep your guests safe or just to see who's the most drunk, it's always fun to have your own breathalyzer at a party. We've seen DIY breathalyzers before, like this one by Craig Smith, but how about an Arduino breathalyzer?
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.
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.
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...
Looking to transmit some super-secret audio communications to your other spy buddies? A laser is the perfect tool for getting your sounds heard from a small distance—without anyone intercepting them— even if it's just a cover of your favorite pop song. A laser audio transmitter uses light rather than radio waves to transmit sound. This is a much more secure way to send audio communications because the laser is a focused beam of light, whereas radio waves are not controlled, so they can be pic...
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.
Dippin' Dots are a fun way to enjoy ice cream, but the price tag is not so fun. Plus, the company filed for bankruptcy last year, so they may not be around much longer. The good news is that you don't need them—you can make your own at home with some ice cream and liquid nitrogen. Redditor hypoid77 posted instructions on how to make your own DIY Dippin' Dots Maker out of a Styrofoam cooler, a couple two-liter bottles, a thumbtack, and some liquid nitrogen. Use the thumbtack to poke a 3-inch p...
André Broessel of rawlemon has developed a solar energy generator that can use both sun and moonlight to create usable power. Oh... and it's gorgeous. The device is essentially a huge glass sphere filled with water that uses a ball lens to refract light in a way that increases energy efficiency by 35 percent. It's completely weatherproof and has an optical tracking device, meaning that it can be incorporated into architecture. Here's a concept design of how it could be used to power buildings...
If you've ever been on your way to a party and felt that your outfit just wasn't flashy enough, engineering student 'Rambo' has got just the thing for you. His homemade LED suit lights up and dances to the beat of the music, and can even be controlled via Bluetooth.
Invented by Philadelphia tinsmith John L. Manson in 1858 for canning and preserving perishables, mason jars are experiencing a major resurgence in the DIY community. In addition to being a handy storage device for both food and non-food items, its old-timey, quaintly antiquated look also makes for good drinking glasses, candle holders, flower vases and eye-pleasing decorations.
Shooting a photo or video in a car can be rather difficult without a proper mount, and if you want to secure your camera outside the car, it can be just plain expensive. Luckily, there are tons of DIY camera mounts for both inside and outside your vehicle, and most of them are pretty cheap to make. Here are some of the best.

You probably already know that your digital pictures have quite a bit of information embedded in them. What you might not know is just how much personal information is included in that metadata, including your camera information, and in some cases, even the precise GPS coordinates of where you took the picture.
Hello! This post is for all who have medium sized or long hair and want to put them up quickly. I suggest you go for a simple small ponytail looking bun. It takes just a few seconds to make it and it looks elegant. It can push your hair a bit forward, above the forehead, so you're hairstyle does not look 'licked'.
Yesterday, Microsoft released the customer preview of its newest version of Office, the first version optimized for both touchscreens and desktop systems. The entire suite got a much-needed facelift and a few new cool features. Here are some of the most notable changes.
Turn the unmarked and unlined moleskine notebook into a productivity tool! All you need are a few small multi-colored Post-It tabs, a Hi-Liter and a regular pen. By color coding the separate sections of the notebook, you can easily flip to needed sections.
In this tutorial, Gary Rosenzweig of MacMost.com briefly goes through the steps to create a basic audio podcast. You must first set up a blog, then create the audio content, then link the audio to the blog posts, and then publicize your RSS feed.
Perfect for attaching the guy line of a tent to a peg or a post, this sliding loop is prized for its ability to adjust up or down, tighter or looser. If only pitching the rest of the tent were so easy.

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...
Instagram is one of the hottest mobile apps to date, yet they have no way to upload photos straight from your computer. You can log into the Instagram web app to like and comment on photos in your feed, but that's about it. Fortunately, there are third-party apps that let you do more on Instagram from your Mac or Windows computer, so you can enjoy Instagram pics on the big screen instead of your tiny iPhone or Android device.
There may come a time when you need to fix your car and you may not have the money needed to do all the maintenance. So the next best choice? Do it yourself of course! In this three part video tutorial you'll find out what it takes to remove the front bumper and grill to a Chrysler 300C.
In the Xbox 360 game Darksiders, you're nearing the end of the game when you get to the Black Throne, which consists of three guardians and Straga. Proceed across the bridge as it constructs itself then enter the main room of the Black Throne. Here you will find Azrael who will tell you about Straga and how he gains great power from the Well of Souls. You will need to defeat the three Guardians that protect the Well of Souls and use their power to destroy the three statues that imprison Azrae...
