Kinect quadrocopter gets a new mission: 3D mapping (video)


In the future, our flying robot overlords won’t just navigate terrain autonomously, they’ll also report back to base with detailed 3D maps of everything they’ve seen — or at least that’s what this homebuilt UAV does in a video released this week. In a nutshell, MIT’s combined its room-mapping Roomba with the Kinect quadrocopter radar developed at UC Berkeley, resulting in a flying contraption sure to be the envy of topographers everywhere. We’re not sure that the world’s robot incumbents will be too happy, though — perhaps MIT should invest in some laser protection next.

Why Does the Sun Look So Weird and Beautiful In this Photo? [Astronomy]

This is a solar eclipse. One like you have probably never seen before, taken by NASA’s Solar Dynamic Observatory in space. It looks really weird, as if the Sun is fizzling away, fading into the darkness of space. Why is the edge of the shadow fuzzy? More »

High-Tech Home Brew Kit Would Make Beer Robot Swoon

The Synergy beer-making kit is a world away from the plastic buckets of student home brew

If Doc Brown ever made home-brew beer, he’d make it in something that looked like this, the Synergy Home Beer Brewing System. The all stainless steel setup will let you mash your own hops and barley, sparge the wort and then let it ferment. There are gas burners built in, and the high mash-tun lets you siphon the wort by gravity, meaning no pump is needed. Finally, all tubes are silicone, which won’t taint flavors, and won’t dry and crack with age or heat.

If the above paragraph leaves you confused, then don’t worry. You mightn’t be ready for this $1,900 setup, but you can do everything with stuff you likely have in your own kitchen (you’ll probably need to buy a big plastic bucket for the fermentation, though). The Synergy kit certainly makes things easier, though, and you’ll look like a real pro.

Is it worth making your own beer? Well, the hassle outweighs the cost savings, but it can be a lot of fun. As a student, I bottled a brew which I called Venusian Death Cell. Some guy on my fine art course had combined the pictures from porn playing cards with horror-themed Top Trumps cards. The last one remaining from his no doubt highbrow project was the Venusian Death Cell, which I photocopied 50 times over and glued to the bottles.

Like I said, a hassle, but lots of fun. The Synergy Home Beer Brewing System is available now, and can be further customized by the fine folks at Synergy Brewing Systems.

Scientists propose a ‘journey to the mantle of the Earth’

This particular “journey” may not involve any humans descending into the Earth, but that doesn’t mean it isn’t still plenty ambitious — a pair of scientists are now proposing to drill to the Earth’s mantle and bring back some samples, effectively picking up where the first attempt to do so left off some fifty years ago. Of course, the key word here is “proposing,” but the scientists, Damon Teagle and Benoît Ildefonse, say that we now have the technology and knowledge necessary to do so, and that drilling could begin by 2020 if everything goes as planned. They’re looking to get things underway well before that, however, and are already planning an expedition in the Pacific as soon as next month where they say they will “bore further into the oceanic crust than ever before.”

Android Exploits Can Help You Fool the Boss

Your soul is slowly shriveling while enduring the second work meeting of the day.

If you don’t get out soon, you’ll fall asleep. Or maybe explode. Or, worse, say something you’ll regret.

Good news, Dilbert: Your problems with the boss are over if you’re using Android, the world’s most popular mobile phone operating system. The platform offers hundreds of apps for spoofing phone calls or texts — or pulling other stunts that can help get you out of work.

Compare that to the limited variety of leg-pulling apps on Apple’s iOS platform, and you’ll see why Android is the mobile OS of choice for shirkers like myself.

April Fool’s Day is a good time to give these Android exploits a look. Get out of that work meeting by using an app to program your Android phone to send yourself a fake text or a bogus phone call.

I get them from Kim Kardashian all the time, forcing me to leave meetings to attend more, um, important business. Having to excuse oneself to go to the bathroom only works so many times when it comes to escaping a meeting.

Even better, hit the boss with pre-programmed fake text messages from Ms. Kardashian. That might get him to stop talking, or it might produce the sudden need to halt the meeting. Either way, the joke’s on him.

An Android application for bogus texting is “Fake-A-Text-Free.” The Android Market and third-party Android markets are littered with similar apps.

Then there’s the app “Fake Me Out of Here!” It’s for the truly lazy. No pre-programming is necessary for this app to make your phone ring with a fake call from anyone in your contact list.

But sometimes the boss just might have something relevant to say, but you still can’t stomach the thought of sitting through the meeting.

If you haven’t played the “bathroom card” too many times, excuse yourself and leave your phone behind. Then secretly record the meeting. Sure, it might be illegal, but nobody has to know. Play back the recording a month later, and you’ll know why you exited stage left.

Some apps to help perform this nefarious deed are appropriately named: They are called “Informant,” “Secret Recorder” and, among others “Spy Recorder Voice Recorder.”

For the 007 diehards, why not secretly record video as well? Yep, there are apps for that.

One of them is called “Spy Phone.” Position your phone, which looks like it’s off, at the correct angle and it starts recording video, and nobody will be the wiser. Another app, the “Android Spy Camera,” promises to secretly take pictures with “no flash and no shutter sound.” You better hope that app lives up to its promises or you may find yourself wishing you could attend a work-related meeting.

So what’s next? You’ve successfully left the meeting. Now it’s time to take this exploit to the next level.

Sure, you could hit the local tavern for the afternoon. But why be so sheepish? Don’t put your Maxwell Smart tendencies to waste.

Go ahead and hit the Bahamas. After your fourth beach-side margarita, you’ll have completely forgotten about that work meeting.

Best of all, your boss won’t even know your lathering up with sunblock. That’s because he’ll think you’ve been abducted to one of the world’s most notorious prisons.

That’s right, go ahead and use FourSquare to check in, or Facebook to “like,” the Diyarbakir prison in Turkey by using GPS-spoofing apps to fake your global positioning. Many apps allow for this digital teleportation, and they are apply named with titles like “Fake GPS Location,”  ”My Fake Location” and, among others, “GPS Route Simulator.”

Better yet, don’t even bother showing up to work. Send your boss a spoofed e-mail from your doctor, informing the Big Kahuna that you’ve got leprosy. There’s a bunch of apps for that. Search for them under “fake email” in the Android Market.

The practice, of course, is legally questionable.

What’s more, the e-mail spoofs might help you get a wage increase without having to explain your new tan.

Upon your return from Diyarbakir, send your boss a spoofed e-mail from your competitor with a message saying the company wants to hire you away.

Sure, it might backfire. Your boss might not give you a raise and instead point you to the door.

But don’t fret. You still got an ace up your sleeve: You used one of a host of Android apps, including “Call Recorder – Total Recall” or “HTC Call Recorder Widget” or tons of others to secretly record a telephone call between yourself and the boss. If you were able to catch him saying anything untoward — like dissing his boss — you might have all the leverage you need to keep yourself in clover indefinitely.

Sure, extortion and clandestine phone recording are illegal. But no worries, the cops might go easy on you if you can hook them up with Kim Kardashian.

Three-In One Lightbulb Is an Energy-Saving Matryoshka

GE’s 3-in-1 bulb lights up instantly yet still saves power

Can’t decide between a warm, instant-on halogen bulb, a long-lasting, low-power compact fluorescent or a plain old incandescent in its familiar bulb shape? You don’t have to. Just buy GE’s new hybrid and you get all three, in one handsome glass bauble.

The bulb looks like any bulb you may have bought in the last hundred years or so, but inside you’ll find a cool CF tube coiled spring-like around a hot halogen core. When you flip the switch, the halogen lamp lights up instantly, and the CF tube starts to warm up. When the tube reaches full power, the halogen lamp winks off.

The bulb, which will start showing up in stores this month, will come in two colors, both of them white: 2,700 Kelvin and a slightly warmer 2,500 Kelvin. They will burn for up to 8,000 hours, eight times the life of an incandescent. You’ll pay between $6 and $10 depending on the wattage and model you choose.

I like this, and I think I may send one to my parents to put in their computer room (yes, they still have a “computer room”). Whenever I Skype them, usually when it’s late and I’m drunk enough to want to talk to them, they flip on the CF light in their room and I am treated to ten minutes of dim orange shapes looming into view on my 27-inch monitor. Finally the lights come up to speed and I can actually make out my mother, at which time the gin finally kicks in and everything goes blurry again.

Rogers’ Xperia Arc and Xperia Play launch details leaked

O Canada, we stand on guard for thee — in this case “we” being the Xperia Arc imaging flagship and Xperia Play gaming handset. We knew this day was coming, but it now looks like Sony Ericsson’s hottest new pair of Android smartphones will be available from Rogers “late April” for $99. Of course, you’ll have to commit to one of those insane 3-year contracts with a minimum $45 voice and data plan for the privilege, but the Gingerbread toting Xperia Arc and Xperia Play could be yours as soon as April 19-21, which is when the devices are expected to ship to stores. While there’s no indication when pre-orders will be starting, folks who pre-order could win a trip to sunny Florida. Just promise to send us pictures of Shamu taken with your new phone if you win, OK?
