LAS VEGAS — Who ever thought a blood-pressure monitor could look cool?

Qardio did. The U.S. medical device maker is obsessed with crafting hospital-grade gear that wouldn’t look out of place sitting alongside your iMac.

The company’s latest product, unveiled during the International CES trade show here, is a smart scale that delivers feedback in the form of a smile or a frown, depending on how your weight is trending.

“It makes you feel good,” said Rosario Iannella, Qardio’s chief information officer.

LAS VEGAS — It seems like everyone is selling some kind of smart light bulb these days, but Sengled is setting itself apart by incorporating wild add-ons like Bluetooth speakers and Wi-Fi repeaters.

That’s right, a light bulb with a speaker.

At a demo during CES Unveiled here, the company showed me its lineup of four smart bulbs, all of which have their own gimmick beyond the to-be-expected remote control functionality through an app.

Imagine walking five street blocks in a city like, say, New York. Then think about climbing that distance straight up.

That’s what Kevin Schmidt does for a living: changing the airplane warning lights at the top of super tall TV towers.

This drone from PrairieAerial caught the guy in action as he climed the now-defunct analog KDLT antenna in Salem, SD. Watch the whole thing as he grabs a vertigo-inducing selfie at the top.

LAS VEGAS — For eight years, Paul Chavand been working hard to bring the world a pair of motorized skates. Why? To revolutionize the simple act of walking. Chavand’s dream is turn a simple stroll into an effortless glide on motorized wheels.

But don’t call them skates. Chavand, a mathematics teacher from France’s Burgundy region, gets rather upset at that. Skates imply imbalance, falling over and wildly flailing arms. Chavand’s Rollkers require no “skating.” You just stand still and the motorized wheels zip you along. Balancing is as simple as standing up, the inventor says.

So instead of “skates,” he calls his invention, rather comically, “under shoes.”

The big question is why you’d want them.

LAS VEGAS — Football in America is under attack after the revelation that concussions cause serious brain damage rocked the NFL. Youth participation has plummeted in the last two years but the folks at Linx have a new solution that will help parents keep track of when their kids are getting pounded too hard on the field.

The Linx IAS sports monitor is a tiny Bluetooth sensor athletes can wear in a skull cap or headband to keep track of every impact on the field, no matter if they’re playing football, lacrosse, soccer, hockey or pretty much any other contact sport.

LAS VEGAS — The small but humbling act of loosening your belt after a big meal is finally over!

Inventor Bertrand Duplat has developed a motorized belt that automatically loosens its grip when your gut bulges.

“The experience of the belt hasn’t changed in centuries,” Duplat told Cult of Mac at CES International. He calls his invention, which certainly will change your belt experience, Belty.

“When you sit down and eat a long dinner, it loosens automatically. It tightens up when you stand up,” he said.

LAS VEGAS — What if your entire life was like a Russian dash cam? Our phones already know where we are and what we’re doing every moment of the day, but the Narrative Clip takes things to the next level.

This tiny little square clips onto your person and takes a 5 megapixel photo every 30 seconds. Apparently wearing such a thing makes you a “lifelogger,” which sounds like a great term to drop on a first date. Then again, once you admit that you’re wearing an always-on camera during a date, it won’t really matter if you call it lifelogging or not. You’re not getting a second shot.

If you can suffer through the selfies, food shots and pet pictures, you can catch a glimpses of the revolutionary art form that is mobile phone photography. Book publisher Pierre Le Govic has positioned himself to be the first important curator of the fleeting beauty on Instagram.

Le Govic, who established a publishing house in France for mobile photography in 2013, has issued Out of the Phone: The Mobile Photo Book 2014 Edition, featuring one picture each from 100 photographers from 25 countries

LAS VEGAS — Not every wearable launched this year will get slapped on your wrist.

Quell, a new electrical-stimulation device designed to help alleviate chronic pain, gets wrapped around the wearer’s calf.

“I like to say it’s like a USB port into your central nervous system,” said Frank McGillin, SVP and general manger of Quell.

While a wave of fitness trackers and the upcoming Apple Watch are drumming up a healthy buzz about wearables, more and more medical devices work with smartphone apps and tap into Apple’s HealthKit platform. Quell doesn’t yet work with HealthKit, but McGillin told Cult of Mac that’s certainly in the cards.

For a man who played a part in coming up with some of the most gorgeous designs in recent history, I’ve never been too sure about the surprisingly bulky appearance of Venus: Steve Jobs’ 256-foot super-yacht.

With that being said, however, a new crop of photos showing the €100 million vessel in full ocean-going mode definitely makes me rethink my views on the subject.

Half-summer house and half Apple Store, it looks every bit the kind of vacay destination that would have helped Apple’s late CEO recuperate after a new iPhone launch — had he ever gotten the chance to use it.

Usually, we tell you what we think about things that come down the Mac and iOS news pipeline. But this time, we want your opinion: what do you think of this iPod Classic smart cover for iPhone that turns your handset into a vintage iPod, like the day of yore?

Google today announced a new Apple AirPlay competitor called Google Cast, which lets you stream audio from a whole bunch of popular apps to Cast-compatible speakers. The search giant has teamed up with a number of popular services for its launch, including Pandora, Rdio, and NPR One.

From forks that tell you whether you’re eating too much, to toothbrushes which quantify your brushing, the post-New Year season always has a few hygiene-related tricks up its sleeve.

Perhaps 2015’s first such device is the so-called Breathometer Mint, which offers something that no other smart device has yet managed — by telling you whether or not you’re suffering from morning breath, as well as measuring your hydration levels.

LAS VEGAS — Everyone hates loudmouth jerks who talk too loudly on their cellphones in public. If this is you know or someone you love, a new startup may have the answer.

Onvocal’s Mix360 is a Bluetooth headset with a microphone that detects ambient sound. So if you’re talking on your cell, you can hear exactly how loud you are and modulate your voice accordingly.

“It’ll end those annoying calls where people can’t hear how loud they are and are shouting into their phones,” said Ashley Waters, a spokeswoman for the Massachusetts-based startup.

LAS VEGAS — For more than 10 years, Michael Wallace and Darin Barri were toy designers. Depressed about plummeting sales because of video games, the pair went on a week long bender to drown their sorrows.

They both loved lychee martinis, which are tricky to make. They dreamed of a smart cocktail mixer that uses weight — rather than volume — to make mixed drinks. So they hacked a kitchen scale with some electronics and coded an app. The resulting system, called Perfect Drink, makes it impossible to screw up martinis and dozens of other cocktails. They took it to Brookstone, who loved it and put it on the market. Eighteen months later, they’ve sold 120,000 units.

Now they’re back with Perfect Bake, a foolproof baking system that uses the weight of ingredients, rather than volume, to guide clueless home bakers.

Dell doesn’t usually impress us with its Android-powered offerings, but its new Venue 8 7840 tablet could be far more impressive than the onslaught of new slates we see at CES this week. It’s powered by a speedy Intel processor, has four cameras, and takes the title of the world’s thinnest tablet to date, measuring just 6mm thick.

Quick: How much does an iPhone 6 cost? If you read this blog at all, you probably know that answer can range wildly depending on a variety of factors: how much storage it’s got, whether it’s subsidized, what carrier it’s on and what coverage you’ve got. Even so, would you ever guess that an iPhone 6 costs $7,500? Well, that’s just what two contestants on The Price Is Right did on a recent episode of the show.

Alcatel Onetouch wanted the world to see its new smartwatch so badly that it actually previewed the device last week ahead of its official unveiling. But at CES in Las Vegas today, the company confirmed a few juicy details we didn’t already know — such as compatibility with iOS devices, and the WATCH’s $149 price tag.

We said that Apple was going to dominate this year’s Consumer Electronics Show — despite not being there in person — and here’s another example of why that’s true.

Although the Apple Watch isn’t out yet, mobile-marketing firm TapSense is taking advantage of CES mania to unveil its plans to release an Apple Watch ad-buying service, aimed at developers. This service will let businesses create ads targeted at individual users of Apple’s upcoming wearables device.

These ads would use “push notifications” to alert customers of specific deals they may be interested in, although only inside apps that have already been opened.

LAS VEGAS — As soon as I saw this Wi-Fi-connected kettle, I wondered to myself: “Why on earth would anyone want a Wi-Fi-connected kettle?”

This is crazy. Connectivity gone mad. It’s got Wi-Fi for the sake of it. It’s a gimmick. Tech trying to solve a problem that doesn’t exist.

But I talked to the CEO, and his answer surprised me. Now I totally want one.

The Smarter Wi-Fi-connected kettle, called the iKettle in the U.K., is so British it’s not funny. Every household in the U.K. has an electric kettle. It’s on all day, every day, making cuppa after cuppa, all day long.

If you’ve ever wanted an ultra-slim hard disk drive to go along with your MacBook Air or other supermodel-thin device, now’s your chance: the Seagate Seven is set to be the world’s thinnest HDD ever — measuring just 7mm thick.

To put that in perspective, that’s 01.mm thinner than even the slimline iPhone 6 Plus: an astonishing engineering feat, which also pulls off the difficult task of being a gorgeous piece of design. On top of that, it offers 500GB of storage, excellent speeds, and USB 3.0 connectivity.

What more could you ask for?

Rumors of a larger 12-inch iPad have been swirling for months now, but we’ve yet to see any credible parts or renders. That may have just changed, though: renders of a larger rear iPad Pro shell, allegedly from a Foxconn factory.

More than a year after Apple broke ground on its futuristic “spaceship” Apple Campus 2, we have another progress report courtesy of a new drone flyover video from Myithz.

As you can see from the video (which looks absolutely stunning on a 5K iMac, thanks to its high resolution), the forthcoming Apple headquarters is really starting to take shape now, as building continues on the $5 billion campus.

Check it out after the jump:

LAS VEGAS — I love basketball, but I have a weakness — I can’t jump.

I’ve hit the gym. I’ve tried jumping exercises.

None of it has worked, but a new fitness sensor called VERT might be the first wearable that finally helps me get above the rim, thanks to its workouts, which are designed to help you improve your leaping ability, while also preventing injuries on the court.

SAN FRANCISCO — It’s easy to see how the UE Megaboom could become your favorite way to listen to music. The new Bluetooth speaker packs great features into a rugged cylindrical package that won’t go tits up if you drop it or leave it out in the rain.

The UE Megaboom is bigger and louder than its predecessor, the similarly shaped UE Boom. It delivers glittering, precise highs and satisfying bass. It’s lightweight and boasts a 20-hour rechargeable battery. All in all, it’s a perfect device for the way we listen to music in the streaming era.
