Samsung will support Alexa and Google Assistant on 2019 TVs

Posted: 06 Jan 2019 07:00 PM PST

Make way, Bixby: Samsung is opening up its 2019 TV lineup to other voice assistants. The company has announced that users will be able to control its upcoming QLED sets with either Amazon Alexa or Google Assistant. But there's one catch: you'll have to provide the assistant device — be it an Echo, Google Home, or other smart speaker — yourself. Samsung's TVs will understand and execute commands they receive from Alexa or Assistant, but the only built-in voice helper will continue to be Bixby.

Also, we're talking about fairly rudimentary support here. Alexa and Google Assistant can control volume, turn your TV on or off, switch inputs, or launch select apps. Bixby has deeper, more advanced capabilities since it's woven into Samsung's...

Samsung’s 75-inch MicroLED 4K TV is a huge step into the future

Posted: 06 Jan 2019 07:00 PM PST

After launching an enormous MicroLED TV called The Wall at last year's CES, Samsung has returned in 2019 with a smaller, 75-inch 4K TV that's a far more practical fit for the living room. It uses the same MicroLED foundation as The Wall, combining "individual tiles of self-emissive MicroLEDs, featuring millions of inorganic red, green and blue microscopic LED chips that emit their own bright light to produce brilliant colors on screen." There's no backlight required, so MicroLED displays can be incredibly thin.

But the bigger appeal of MicroLED is picture quality that should rival or beat OLED without any of the pitfalls of using an organic compound; that's what the O in OLED stands for, after all. In theory, MicroLED should deliver...

Nemeio’s e-ink keyboard lets you customize every key

Posted: 06 Jan 2019 06:55 PM PST

Nemeio, a new brand under French tech conglomerate LDLC, has taken the concept of a customizable software keyboard to whole new heights. At the annual CES Unveiled showcase here in Las Vegas, the company showed off an e-ink keyboard, yet to be officially named, that can be customized key by key. Nemeio imagines the market for such a device includes bilingual travelers or those who cross time zones and language barriers often for work, as well as anyone who's ever wanted all the power of Apple's MacBook Pro Touch Bar in a full keyboard interface.

If you happen to be a keyboard or CES aficionado, you also might remember Razer's ill-fated Switchblade, a concept keyboard from 2011 that tried to pull off the same thing in full color and for...

Leading crypto wallet adds Bluetooth support for mobile bitcoin access

Posted: 06 Jan 2019 06:46 PM PST

On Sunday at CES, the crypto wallet company Ledger revealed its latest device — the Bluetooth-enabled Ledger Nano X. The device is roughly similar to the previous Nano S, offering more support for multiple wallets and coin types but leaving internals otherwise the same. But Bluetooth will allow the X to connect to mobile devices through the new Ledger Live app, a powerful new way to access hardware wallets through your phone.

Hardware wallets let you hold bitcoin locally without keeping them in an exchange, a more flexible version of simply writing down your key on a piece of paper. The devices typically require a PIN to unlock and support multiple physical devices tied to the same key, providing strong protection against theft or...

Targus made a backpack with a wireless charging pocket

Posted: 06 Jan 2019 06:39 PM PST

Here's the new Targus Mobile VIP+ backpack, which has a built-in battery and a nifty Qi wireless charging cradle in one of the side pockets. The cradle holds your phone in place to keep it charging even as you move around, and it fits phones up to the iPhone XS Max in size — I tried my XS Max in Apple's leather case and it fit just fine.

The cradle connects to the internal battery with a standard USB cable, so you can replace it with a bigger battery if you want, and there's another pocket that blocks RFID signals if you're the paranoid type. Is someone trying to hack your keycard to the mainframe while you desperately run away with a dead phone battery? This could be the bag for you.

It's also a nice Targus bag, with the...

New Game of Thrones, Watchmen footage airs during Golden Globes

Posted: 06 Jan 2019 06:27 PM PST

The first footage from HBO's upcoming Watchmen series and Game of Thrones' final season aired during tonight's Golden Globe awards.

Although it was only a few seconds' worth, Game of Thrones' footage includes a look at Daenerys Targaryen arriving in Winterfell with Jon Snow. Daenerys can be seen talking to Sansa Stark, with Sansa declaring Winterfell's allegiance to the Targaryen queen. This isn't the first Game of Thrones announcement that HBO has made in anticipation of the show's final season, but it's the first clip that brought us any new footage.

HBO's sizzle reel also included a first real look at its upcoming Watchmen series, which is being handled by The Leftovers and Lost creator, Damon Lindelof. The footage doesn't give too...

SpaceX moon tourist scores most retweeted tweet ever with promise of free money

Posted: 06 Jan 2019 06:23 PM PST

Yusaku Maezawa, founder of massive Japanese online clothing retailer Zozotown, is a rich guy. Rich enough to pay Elon Musk's SpaceX a serious amount of money to become a passenger on a trip to the moon, and also rich enough to rack up the most retweets in history by promising to give away almost a million dollars.

Styled in the fashion of a Japanese new year's greeting card, which often contain gifts of money, Maezawa's January 5th tweet says he'll personally pay one million yen (about $9,200) to 100 people that follow and retweet him. The deadline is the 7th; Maezawa says he'll contact the winners via direct message.

I’m tired of waiting for water to boil

Posted: 06 Jan 2019 05:39 PM PST

Instant, on-demand water heaters are nothing new for your home. Now a company called Heatworks is trying to take that same technology and miniaturize it for consumer products. It has two such gadgets on display here at CES 2019 — and the more interesting to me is the Duo carafe. If you want hot water for coffee or tea, it promises to heat it instantly as you pour it out of the carafe instead of slowly heating the entire pitcher of water.

It heats the water instantly with a technology Heatworks calls an "Ohmic array." That's "ohmic" as in "ohm" as in electrical resistance. It uses the water itself as an electrical conductor between graphite electrodes, vibrating the minerals in it, as CEO Jerry Calahan explained to me here at the event....

Your Mac’s speakers can make movies and music sound 3D with this app

Posted: 06 Jan 2019 05:21 PM PST

Nahimic has been offering its 3D audio technology on PCs for years (specifically, MSI's gaming PCs), but at CES 2019, the company is expanding in a big way with a new Mac app that promises to bring that same 3D audio sound to your laptop, all without needing any new hardware.

I had the chance to demo the app here at CES, and it actually seems to do what it says on the can — it makes music and movies sound like they're in 3D audio. Or, if not fully 3D audio (since there's no cheating the fact that most of this content just isn't mastered for 3D sound), at least a fuller and richer sound that what Mac speakers usually put out.

Music in particular benefited in the demo, seeing a dramatic...

L’Oréal’s newest prototype detects wearers’ skin pH levels

Posted: 06 Jan 2019 05:00 PM PST

L'Oréal is continuing to invest in tech, and today at CES, the company introduced its newest wearable prototype that detects skin pH levels. L'Oréal says varying skin pH levels can cause inflammatory skin conditions, like eczema and dryness. The company wants dermatologists to use this new device's data to create health plans while also empowering users to learn about their own skin.

Wearers place the device on their inner arm and leave it there for between five and 15 minutes, however long it takes for those two dots to take on color. They then have to open the My Skin Track pH app on their phone and take a picture of it. (Those dots can assess sweat biomarkers like pH, glucose, lactate, chloride, as well as local sweat loss and sweat...
