Zack Snyder reveals the Batmobile for ‘Batman v. Superman’ movie

Ben Affleck has quite a ride. It was always going to be hard to top The Dark Knight’s Tumbler, but the Batmobile in Zack Snyder’s Batman v. Superman puts up a pretty solid fight. Seriously: check out that weapon on the front. You can see the photo in high resolution over at Imgur.

Set photos of the Batmobile leaked earlier today, and clearly, Snyder wasn’t happy with them. He just published this new photo on Twitter, and it’s evident that his Batmobile is far better looking than it appeared in those earlier grainy shots. This shot’s photographer, Clay Enos, even calls out the poor quality of the earlier images. “iPhone photography is great,” he writes, “but some things deserve more.”

SanDisk’s 512GB SD card will hold all the 4K video you can handle

If you’ve been dabbling in 4K video recording, you probably know that most SD cards won’t cut it; you’ll be thankful if you have enough space for a wedding video, let alone a magnum opus. SanDisk may have a solution for that space problem in its new, extra-capacious 512GB Extreme Pro SDXC card. It’s fast enough (95MB/s) to shoot interruption-free 4K, but also has more than enough storage for a day’s worth of movies and high-speed photography. Capture 60Mbps video on Sony’s AX100, for example, and you could theoretically keep going for almost 19 hours. You’re going to pay dearly for all that headroom, though. The 512GB card sells for a whopping $800 — unless video production is your bread and butter, you’re probably better off “settling” for the Extreme Pro’s 128GB or 256GB variants.


Is this the smart watch you’ve been looking for?

Today I finally got to try on a smart watch that fits my wrist, looks good, and purports to be full-featured yet not overly annoying.

By Rachel Metz

While other smart watches I’ve tried and spied have been mostly clunky, finicky, ugly, and, frankly, not all that smart (see “So Far Smart Watches Are Pretty Dumb”), Apple’s just-announced Apple Watch looks stylish, thoughtfully designed, extremely customizable, and full of great technology that is cleverly implemented. In other words, it appears to be awesome.

Foldable Wind Turbine Fits In Backpack, can Charge Laptop

While most wind turbines are getting bigger – like a U.K. design with blades as long as a football field – a few are going in the opposite direction and aiming to become as small as possible. A new 3-D printed wind turbine is small and lightweight enough to fit in a backpack.

Now raising funding on Kickstarter, the  AirEnergy3D is portable enough to take on a camping trip, or move from a rooftop to a balcony to catch the biggest breeze. It can be fully assembled without any tools. Devices like a laptop or phone can plug directly into the turbine to charge, or it can send electricity back into a household power system.


Google’s panoramic Photo Sphere Camera app reaches the iPhone

Google’s all-encompassing Photo Spheres are no longer limited to Android users and those comfy with photo stitching software — the internet giant has just released a Photo Sphere Camera app for the iPhone-toting crowd. As before, it lets you create 360-degree panoramas just by spinning around in place. You can both share the resulting masterworks with others (including the Google Maps community) and check out others’ spheres in the Views hub. It’s overkill if you’re perfectly content with alternative panoramic apps or plain old landscape shots, but it’s hard to object to having one more way to liven up your vacation photos. Swing by the App Store to check out Photo Sphere for yourself.

Vizio recalls 245,000 HDTVs to fix tip prone stands

Vizio’s E-Series has been excellent cheap option for big HDTVs with full-array LED backlighting that enhances picture quality, but several versions are being recalled for a serious safety issue. According to the details posted by the Consumer Product Safety Commission, 39- and 42-inch models sold since late last year have a stand that can fail and lead to the TV tipping over. Vizio says there haven’t been any injuries as a result of 51 tipovers reported among the recalled sets, but HDGuru points out stats indicating thousands are injured every year in such accidents — meaning we should probably all take a second look at our TV stands, or at consider a wall-mount. If you have one of the 245,000 or so TVs being recalled, the recommendation is to detach the stand immediately and request a replacement (even if yours is wall-mounted you should request one, just in case it’s taken down later). Vizio is notifying owners, and has a website where they can check their set’s serial number to see if it’s affected before requesting the fix.


School district chose Google Chromebooks

When David Andrade became the CIO for the Bridgeport Public Schools District in Connecticut last year, he knew he was in for a big challenge.

Only a few old desktop PCs were located in the district’s public schools, and his limited budget made it difficult to place a big order for new computers. Being in a working-class community, where 95% of the students receive free or reduced-cost lunches, most students didn’t have access to computers outside of school, either.

So when he was asked to bring more computers to Bridgeport public schools, Andrade immediately thought of Google’s Chromebook.

Security researchers say broken USB security can take over Macs or PCs

The USB standard has a fundamental security flaw that allows an attacker to take over any device it is connected to, whether PC or Mac, say security researchers in a frightening piece by Wired.

Describing the proof-of-concept Karsten Nohl and Jakob Lell plan to present at the Black Hat conference next week, they say the weakness is fundamental to the way in which USB works. Rather than storing malicious files on a USB device, the researchers managed to hack the USB controller chip that enables a USB device to communicate with a computer, changing its firmware. That means it can allow absolutely any USB device, from a USB key to a keyboard, to be compromised.
