In this article, I'll show you how to make a high-powered, long-range, air-powered rocket gun. This launcher is based on a sprinkler valve, a modified propane tank, and a few other components. Though not hard to make, this device is VERY dangerous! The rocket can seriously harm, if not kill any living thing it's shot at. Here's a video of it in action, quite an accurate shot by my friend Chris... Parts
Christian Cantrell, Adobe's Air Product Manager and Evangelist, has released a video to demo websites that take advantage of the motion sensors in a mobile phone, tablet, or laptop via JavaScript. Now, let's take a look through the code and break down the core pieces that you'll need in order to build your own sites that can determine the 2-axis tilt, 3-axis gyroscope, and compass direction of the mobile device it's being displayed on.
You're never too young to start building your vast swarm of robotic minions. Taking over the world requires a whole lot of robots. The sheer volume of robots needed means your first wave will have to be made of cheap materials. After they take over key resources, you can upgrade to Kevlar and titanium. But to start, let's make popsicle stick insect robots!
This article is all about creating content and using it to build links to your website. Content, meaning articles, videos, and even podcasts is now really the new advertising. That’s because people go to the internet to look for information, not look at advertising. So you need to create compelling content about your business, your industry in general and any topics connected to your entire field that people will want to read, listen to or watch.
This article is all about creating content. This is a very important concept to grasp because the content that you create for a website is going to be the basis for how you will advertise and promote that website. Content, meaning articles, videos, and even podcasts is now really the new advertising. Instead of traditional types of advertising and instead of the traditional separation between editorial content and advertising, that has gone the way of the dinosaur.
In this article, I'll be covering Triggers and Coils, part two of the series (see part one here). Generally, a simple EMP generator consists of four components; a capacitor, a transformer, a trigger and a coil of copper wire. The transformer component can be varied, but the coil is very important, and must be precisely tuned.
When you buy computer parts, it can be a tough decision where you want to put all of your hard earned dollars into. Not only that, but when you buy a top of the line component, 3 months later (at most), your hardware will likely be outdated. This puts consumers like us in a bit of a pickle when it comes to purchasing, especially on a tight budget.
In honor of the new Astronomy World, I thought we should look at a few planetary icosahedrons. The icosahedron is the most round of the Platonic solids with twenty faces, thus has the smallest dihedral angles. This allows it to unfold into a flat map with a reasonably acceptable amount of distortion. In fact, Buckminster Fuller tried to popularize the polyhedral globe/map concept with his Dymaxion Map.
"Google+ is dead." How many times have you read that in the past few weeks? It seems like I can't get away from this notion that Google+, as a social network, is a total failure. Don't feel too sorry for them, though. +Bradley Horowitz isn't worried. In an interview with VentureBeat, he explains, “Six months from now, it will become increasingly apparent what we’re doing with Google+. It will be revealed less in what we say and more in the product launches we reveal week by week.” Indeed, som...
Increasingly, I'm turning to Google+ as a source of news, and it looks like I'm not the only one. On Thursday, news of a small earthquake broke on both Twitter and Google+. One curious user, +Keith Barrett, decided to try and find out which social network was faster with the news. Turns out it was a tie. As Google integrates Google+ more closely with the rest of its services, and more users post relevant stories, I think we'll start to see Google+ as a place that can create and break stories,...
It’s been a pretty big week for Google, and Google+ itself. There were a number of articles proclaiming the end of Google+, because allegedly traffic dropped over 60% after it opened to the public. Then +Steve Yegge accidentally posted a long rant on Google+ itself, which was originally meant only for Google employees and colleagues to see. Interestingly enough, the most inflammatory content wasn’t actually about Google itself, but about the horrible work environment at Amazon. The accidental...
By now you’ve heard about the iPhone 4S announcement, possibly through our article about Apple’s newest smartphone. However, the star of the show was not the only announcement, so here are a few other announcements that were served along side the main entrée this morning. Let’s talk iCloud, iPod, iOS, and more.
The lack of a search function within Google+ is driving me crazy. It takes me way too much time to find the posts I want to save and refer back to, and it's counter-productive for Google to launch their social networking product without an integrated search.
We're ending the week with a lot of big announcements and updates. To date, Google+ has updated its name policy, but is still forbidding pseudonyms. Blocking people on Google+ became even easier, and yesterday, games on Google+ launched.
Whereas yesterday's segment of Making Art on Your iOS Device focused on the technical elements of drawing from life, today we enter the painterly realm of David Hockney and Jorge Colombo.
Mediocre free Flash game websites are all too common. Many of them thrive off peddling the same few popular games to fans who have slim cause to pick one over the other. They thrive off the indifference of casual gamers and an environment that does not have to stand out to survive, only appeal to the lowest common gaming denominator with tower defense clones and brightly colored Peggle knockoffs. In that context, what Nitrome is doing seems downright commendable.
Three years ago, Double Fine productions held an in-house event called the Amnesia Fortnight. The company was split into four teams, each of which set out to spend two weeks developing an idea for a small game and present it to the other groups at the end of the duration. All of the ideas turned out to be winners, and founder/owner Tim Schafer secured publishing deals for all four games to be released on a combination of XBLA and PSN. In honor of the excellent Trenched becoming the third game...
Sticking with our theme of XBLA games with uninspiring names, we have Outland. This game shares its name with an unrelated sci-fi cult film from 1981, unrelated comic strip from the '90s, and unrelated region in World of Warcraft. Didn't exactly try hard to build name recognition. Other than that, Finnish developer Housemarque has created the best 2D platformer I've seen in years.
Welcome back to the two-part series of Ten foods to eat for clear, acne-free skin. Check out part 1 here.
One of the common mistakes I see a lot of candidates make when they go to an interview is that they think it is a question and answer session. They approach the interview with a mindset that their role is to be prepared to answer a bevy of questions thrown at them. This puts you in a passive role, playing defense. A much more effective approach is to go into the interview with the mindset that you are a salesperson, and the product you are selling is you. You want to convince the employer tha...
Watch enough Glee and Buffy's Once More, With Feeling and it will never fail to instill the urge to do something stupid in public. And hey, what better way to do this than to drag others down with you? Welcome to the world of flash mobs, and in just a few simple steps you too could be arrested!
Hi OLers read the following article to gain some great insight into the mischevious advertising ways of food labels. Thanks to the New York Times for this great article below. Happy Eating6 Meaningless Claims on Food LabelsAlthough food labels are supposed to tell us exactly what’s in the food we’re buying, marketers have created a language all their own to make foods sound more healthful than they really are.Today’s “Consumer Ally” column on AOL’s WalletPop site explores misleading food-labe...
Three-dimensional printing is one of the many wonders of modern technology. It's the first step towards real life Star Trek replicators and Timeline-esque teleportation chambers. While we aren't at the level of reconstructing strands of DNA, it's already possible to make tons of fun and useful designs on a 3D printer.
It turns out that the popularity of soft circuit electronics has leaked out of the interwebs and into the hands of the U.S. military. Soft circuit electronics allow you to literally sew electronics circuits into fabric using flexible conductive thread instead of wire. Soft circuits can be used for all sorts of fun projects, like the TV-B-Gone Hoodie and the Heartbeat Headband.

It's once again Monday, which means it's time to highlight some of the most recent community submissions posted to the Math Craft corkboard. Since two of these posts were on polyhedral versions of M.C. Escher's tessellations, I thought we'd take a look at building a simple tessellated cube based off of imitations of his imagery.
Torus knots are beautiful knots formed by wrapping a line around a torus and tying the ends together to form a loop. The resulting knot has a star-like appearance when viewed from above. The 36 examples with the least number of crossings can be seen at the Knot Atlas's page on torus knots.
Google Reader is ostensibly just an RSS aggregator, a tool that lets you catch up on your favorite blogs. How could Google have anticipated that getting rid of its social features could have angered so many people who were actually using it as their default social network, and who enjoyed it precisely because it didn't function like Facebook or Google+?
One of my favorite simple projects is building two circle wobblers. I love how such a simple object amazes with its motion. The two circle wobbler is an object made out of two circles connected to each other in such a way that the center of mass of the object doesn't move up or down as it rolls. This means that it will roll very easily down a slight incline. It will also roll for a significant distance on a level surface if you start it by giving it a small push or even by blowing on it!
Last Thursday, on October 7th, indie game developers from around the world walked down a red carpet in Santa Monica, California in the hopes of winning an IndieCade award. We previously discussed the IndieCade festival and conference, but the award show is a smaller, more inclusive event that provides finalists the opportunity to see their project on stage with rewards by sponsors such as LG, who presented this year’s ceremony.
This week seems to have gone by in a flash. Maybe it was the three day weekend, but I don't think it accounts for the flurry of activity I've been seeing on Google+. Updates, debates, and new initiatives are unfolding every day, and the best part is that most of them are coming from outside of Google. People love Google+ so much that they want to evangelize to others about it. What more could Google+ ask for?
This week, Google held back on introducing a slew of new Google+ features, and introduced new Chrome extensions instead. The new additions won't replace of your favorite Chrome extensions, but they are very useful, and elegant.
Last week's round up was all about third party services that sprang up to fill any Google+ voids. This week, I'll let you know how to keep up with the latest Google+ updates, and give you some great tips for interacting with your followers.
Facebook games are ostensibly all about connecting their players. Yet, in many ways they exist on an isolated island. That's one of the reasons traditional gamers and game franchises have avoided Facebook in the past. And all of the breakout hits so far on Facebook have been cheap PC game ripoffs from the 90s, like FarmVille and ports of other popular casual games.
The philosophy of street art is a long and complex one. This is just the first in a series of the individual street art philosophys i have come across.
Minecraft was first released just a few years ago, but when a paradigm-shifting piece of media comes along the rest of the world is quick to take inspiration from it. The absolutely terrible XBLA knock-off FortressCraft was the first, and last month a much more interesting game called Terraria came out on Steam for $9.99. It is clearly inspired by Minecraft, and there is a long checklist of identical features. It is, nonetheless, a very different product, and just might be called the first in...
For most Americans, the bane of the hangover is typically remedied by lots of water, painkillers, greasy food, and a day wasted on the couch. But if you're tired of potato chips and fried eggs, perhaps it's time you enter unfamiliar territory. Below, a combination of unorthodox methods for taming the beast, derived from science, sparkly Whole Foods new ageism, and the far East.
If you're a lucky owner of the iPhone 4, you know that the upgrade to its camera app includes a front-facing camera feature which acts like a video cam on your computer. Apple, of course, intends the front-facing feature to be mainly used for the FaceTime application which enables you to hold video phone conferences with other iPhone 4 and Mac users who have FaceTime installed on their device. This is all well and good, but there several other ways the front-facing camera can be used.
I've decided to write this post so some of the fledgling street artists who may or may not follow this world in the future are informed about two things in the urban art world that are either not discussed at all, or distorted (intentionally or otherwise) to the point of misinformation. Those two things are, as the title says, the dangers of street art, and the morals of street art.
Guiding internet users to useful content is one of the most lucrative businesses in the world. This process is called aggregation. Google and other search engines form the top of the food chain, aggregating all of the content on the web in response to queries. There are all sorts of other important aggregators though, and you probably use at least one every day: Fark and Reddit for web content, Rotten Tomatoes for movie reviews, and Metacritic for a variety of media, but most importantly, vid...
