How To: Make an Exploding Ashtray Prank for April Fool's Day

News: DIY Papercraft Architecture with Lighting

This is probably the least "Mathy" thing I will ever post. In my opinion, it's impossible to have architecture that isn't mathematical in some sense, so I am posting it anyway. Two years ago, I made a papercraft version of a cathedral in Christchurch New Zealand (It was severely damaged in an earthquake earlier this year) and cut holes for all of the windows and lit it with LED lights. I gave it to my Mom as a Christmas gift. I thought it made for a pretty amazing "Christmas Village" piece.

News: Get YouTube's New Layout Today with a Simple JavaScript Hack

As many of you may have noticed, nearly every Google product (i.e. Gmail, Google search, etc.) has gone through a bit of a makeover since the release of Google+. Big blocky buttons and enormous font sizes are apparently the thing of the future, and with a cool JavaScript hack, you can have a goofy YouTube, too! Now, I'm actually just being a bit facetious, the new YouTube is really the only thing that I like out of all of Google's recent redesigns. It looks pretty sleek.

More Speed without buying expensive hardware. Windows Vista was never the step up in performance that people hoped for after XP.

News: Steve Jobs and His Legacy

I was working on a different Google+ Insider's Guide post when suddenly, my Google+ stream started filling up with news of Steve Jobs' death. Since that moment, many people in the tech industry have paused to reflect on the legacy that Steve Jobs left behind, and talk about what his vision meant for the rest of the industry, and for them personally. There's no tech sector that was untouched by Steve Jobs' influence, and that includes Google.

News: Planning a Scavenger Hunt Based on Age

For any scavenger hunt to become a hit, you need to contemplate the age groups or capability levels of your persons who are actually going to take part. It's fairly apparent that the scavenger hunt easy enough to end up being completed by young kids could jolly well be boring for grownups that wouldn't be interested in something so easy. However, it is also a fact that integrating exactly the correct quantity of intricacy for various age ranges is usually pretty difficult. What do seven year ...

News: Friday Indie Game Review Roundup: Grand Theft Auto's Sci-Fi Genesis Granddad

Grand Theft Auto 3 was the biggest video game of the last decade, by far, introducing open-world adventure games to consoles, a genre that now rivals shooters and sports games for market dominance. A huge map, decentralized narrative, and myriad of interlocking quests and objectives that happen in a flexible order all became hallmarks of the "new" genre, along with the ability to shape the morality and reputation of your character. And most importantly, all of the quests and stories are compl...

News: World's First 3D Printed UAV Takes to the Skies

The use of unmanned aerial vehicles (UAVs) has been widely used by the military for surveillance and reconnaissance missions—even armed combat. But there are other beneficial applications of an unmanned aircraft, such as search and rescue operations, scientific exploration, locating mineral deposits, transporting goods and even filming bikini models. But drone development can be pretty pricey, unless you just happen to have a 3D printer...

News: Japan's Flying, Tumbling Reconnaissance Sphere Soars at 37 MPH

Flying orbs. At first, you might think of the Tall Man and his army of flying sentinel spheres, equipped with zombie brains and a mini-arsenal of saw blades, drill bits and shooting lasers. But these flying orbs weren't conceived from the evil mind of a superhuman mortician—they were designed by Fumiyuki Sato, a researcher at the Japanese Defense Ministry's Technical Research and Development Institute—for something other than deadly deeds.

News: Cantio Helps You Discover New Music (Using YouTube)

When it comes to finding great new tunes for your music collection, the last place you would think to look is YouTube. But more and more artists are posting music videos on the popular video hosting site as a means to getting noticed and hopefully—building a fan base. And since YouTube is not just a music video site, there's quite a bit of junk to sift through, making it virtually impossible to find new songs to add to your iPod's repertoire... unless you use Cantio.

How To: Test Drive Gmail's New Interface

Google's hard at work beefing up their new Google+ social network, and while they continue to improve new features like Circles and Hangouts, they haven't lost track of their other online features already widely in use. If you're already a part of the Google+ project (currently closed to invites right now), you've probably noticed the changes in Picasa Web, but Gmail has been getting some great updates as well—and you don't have to be in the Google+ network to use them.

LeafSnap: Identify Tree Species in Just One Click

Being a Southern Californian, I typically miss out on the incredible springtime bloom of flowering trees in the East. But not this year. By some stroke of luck, I was in Boston early last week, and witnessed the most spectacular trees and foliage at their prime—lilac, magnolias, crabapples, dogwood, and many more.

News: Bat Cave in San Francisco

What do you do when you desperately need to put a parking garage into the bottom floor of your Victorian apartment building, but the city's Department of Planning says "No". The simple and expensive answer: Create an elaborate secret garage door. If you own a pretty building, it is well within the jurisdiction of the Landmark Commission to inform you that even though you own the piece of property, you cannot remodel it any way you want. Seems un-American. But in San Francisco, specifically th...

News: Hulu Plus a Negative on Xbox Live?

If you powered up the ol' Xbox 360 last night to watch Netflix, you probably noticed that a new streaming service moved into Xbox LIVE—Hulu Plus. Netflix finally has some competition. Or maybe not. But with a week of free service, they're sure to attract some would-be watchers.

News: Birds as the Ultimate DIY Architects

The widely used expression "free as a bird" intimates an enviable existence: delicate, yet mighty wings transporting to destinations no human could so breezily venture. But despite their fanciful, superhero ability, in truth, the avian race leads one of the most difficult existences in the animal kingdom. Yes, birds have existed for eons—they likely evolved from small dinosaurs of the Jurassic period—but for these creatures, life can be ruthless.
