A project by students at Carnegie Mellon could save lives. Called the HopeBand, the wristband senses low blood oxygen levels and sends a text message and sounds an alarm if danger is imminent.

“Imagine having a friend who is always watching for signs of overdose; someone who understands your usage pattern and knows when to contact [someone] for help and make sure you get help,” student Rashmi Kalkunte told IEEE. “That’s what the HopeBand is designed to do.”

The team won third place in the Robert Wood Johnson Foundation’s Opioid Challenge at the Health 2.0 conference in September and they are planning to send the band to a needle exchange program in Pittsburgh. They hope to sell it for less than $20.

Given the more than 72,000 overdose deaths in America this year, a device like this could definitely keep folks a little safer.

There’s a lot of talk about the many potential uses of multi-legged robots like Cheetahbot and Spot — but in order for those to come to fruition, the robots actually have to go out and do stuff. And to train for a glorious future of sewer inspection (and helping rescue people, probably), this Swiss quadrupedal bot is going deep underground.

The robot is called ANYmal, and it’s a long-term collaboration between the Swiss Federal Institute of Technology, abbreviated there as ETH Zurich, and a spin-off from the university called ANYbotics. Its latest escapade was a trip to the sewers below that city, where it could eventually aid or replace the manual inspection process.

ANYmal isn’t brand new — like most robot platforms, it’s been under constant revision for years. But it’s only recently that cameras and sensors like lidar have gotten good enough and small enough that real-world testing in a dark, slimy place like sewer pipes could be considered.

Most cities have miles and miles of underground infrastructure that can only be checked by expert inspectors. This is dangerous and tedious work — perfect for automation. Imagine instead of yearly inspections by people, if robots were swinging by once a week. If anything looks off, it calls in the humans. It could also enter areas rendered inaccessible by disasters or simply too small for people to navigate safely.

But of course, before an army of robots can inhabit our sewers (where have I encountered this concept before? Oh yeah…) the robot needs to experience and learn about that environment. First outings will be only minimally autonomous, with more independence added as the robot and team gain confidence.

“Just because something works in the lab doesn’t always mean it will in the real world,” explained ANYbotics co-founder Péter Fankhauser in the ETHZ story.

Testing the robot’s sensors and skills in a real-world scenario provides new insights and tons of data for the engineers to work with. For instance, when the environment is completely dark, laser-based imaging may work, but what if there’s a lot of water, steam or smoke? ANYmal should also be able to feel its surroundings, its creators decided.

So they tested both sensor-equipped feet (with mixed success) and the possibility of ANYmal raising its “paw” to touch a wall, to find a button or determine temperature or texture. This latter action had to be manually improvised by the pilots, but clearly it’s something it should be able to do on its own. Add it to the list!

You can watch “Inspector ANYmal’s” trip below Zurich in the video below.

Fitness trackers and heart-rate monitors are all well and good, but if you want to track activity inside the body, the solutions aren’t nearly as convenient. Iota Biosciences wants to change that with millimeter-wide sensors that can live more or less permanently in your body and transmit wirelessly what they detect, and a $15 million Series A should put them well on their way.

The team emerged from research at UC Berkeley, where co-founders Jose Carmena and Michel Maharbiz were working on improving the state of microelectrodes. These devices are used all over medical and experimental science to monitor and stimulate nerves and muscle tissues. For instance, a microelectrode array in the brain might be able to help detect early signs of a seizure, and around the heart one could precisely test the rhythms of cardiac tissues.

But despite their name, microelectrodes aren’t really small. The tips, sure, but they’re often connected to larger machines, or battery-powered packs, and they can rarely stay in the body for more than a few weeks or months due to various complications associated with them.

Considering how far we’ve come in other sectors when it comes to miniaturization, manufacturing techniques and power efficiency, Carmena and Maharbiz thought, why don’t we have something better?

“The idea at first was to have free-floating motes in the brain with RF [radio frequency] powering them,” Carmena said. But they ran into a fundamental problem: RF radiation, because of its long wavelength, requires rather a large antenna to receive them. Much larger than was practical for devices meant to swim in the bloodstream.

“There was a meeting at which everything died, because we were like two orders of magnitude away from what we needed. The physics just weren’t there,” he recalled. “So were like, ‘I guess that’s it!’ ”

But some time after, Maharbiz had a “eureka” moment — “as weird as it sounds, it occurred to me in a parking lot. You just think about it and all these things align.”

His revelation: ultrasound.

Power at the speed of sound

You’re probably familiar with ultrasound as a diagnostic tool, for imaging inside the body during pregnancy and the like — or possibly as a range-finding tool that “pings” nearby objects. There’s been a lot of focus on the venerable technology recently as technologists have found new applications for it.

In fact, a portable ultrasound company just won TechCrunch’s Startup Battlefield in Lagos:

Iota’s approach, however, has little to do with these traditional uses of the technology. Remember the principle that you have to have an antenna that’s a reasonable fraction of an emission’s wavelength in order to capture it? Well, ultrasound has a wavelength measured in microns — millionths of a meter.

So it can be captured — and captured very efficiently. That means an ultrasound antenna can easily catch enough waves to power a connected device.

Not only that, but as you might guess from its use in imaging, ultrasound goes right through us. Lots of radiation, including RF, gets absorbed by the charged, salty water that makes up much of the human body.

“Ultrasound doesn’t do that,” Maharbiz said. “You’re just Jell-O — it goes right through you.”

The device they put together to take advantage of this is remarkably simple, and incredibly tiny. On one side is what’s called a piezoelectric crystal, something that transforms force — in this case, ultrasound — into electricity. In the middle is a tiny chip, and around the edge runs a set of electrodes.

It’s so small that it can be attached to a single nerve or muscle fiber. When the device is activated by a beam of ultrasound, voltage runs between the electrodes, and this minute current is affected by the electrical activity of the tissue. These slight changes are literally reflected in how the ultrasonic pulses bounce back, and the reader can derive electrophysiological voltage from those changes.

Basically the waves they send power the device and bounce back slightly changed, depending on what the nerve or muscle is doing. By sending a steady stream of pulses, the system collects a constant stream of precise monitoring data simply and non-invasively. (And yes, this has been demonstrated in vivo.)

Contained inside non-reactive, implant-safe containers, these microscopic “motes” could be installed singly or by the dozen, doing everything from monitoring heart tissue to controlling a prosthesis. And because they can also deliver a voltage, they could conceivably be used for therapeutic purposes, as well.

And to be clear, those purposes won’t be inside the brain. Although there’s no particular reason this tech wouldn’t work in the central nervous system, it would have to be smaller and testing would be much more complicated. The initial applications will all be in the peripheral nervous system.

At any rate, before any of that happens, they have to be approved by the FDA.

The long medtech road

As you might guess, this isn’t the kind of thing you can just invent and then start implanting all over the place. Implants, especially electronic ones, must undergo extreme scrutiny before being allowed to be used in even experimental treatment.

Fortunately for Iota, their devices have a lot of advantages over, say, a pacemaker with a radio-based data connection and five-year battery. The only transmission involved is ultrasound, for one thing, and there are decades of studies showing the safety of using it.

“The FDA has well-defined limits for average and peak powers for the human body with ultrasound, and we’re nowhere near those frequencies or powers. This is very different,” explained Maharbiz. “There’s no exotic materials or techniques. As far as constant low-level ultrasound goes, the notion really is that it does nothing.”

And unlike a major device like a medication port, pump, stint, pacemaker or even a long-term electrode, “installation” is straightforward and easily reversible.

It would be done laparoscopically, or through a tiny incision. said Carmena. “If it has to be taken out, it can be taken out, but it’s so minimally invasive and small and safe that we keep it,” he said.

These are all marks in Iota’s favor, but testing can’t be rushed. Although the groundwork for their devices was laid in 2013, the team has taken a great deal of time to advance the science to the point where it can be taken out of the lab to begin with.

In order to get it now to the point where they can propose human trials, Iota has raised $15 million in funding; the round was led by Horizons Ventures, Astellas, Bold Capital Partners, Ironfire and Shanda. (The round was in May but only just announced.)

The A round should get the company from its current prototype phase to a point, perhaps some 18 months distant, when they have a production-ready version ready to present to the FDA — at which point more funding will probably be required to get through the subsequent years of testing.

But that’s the game in medtech, and all the investors know it. This could be a hugely disruptive technology in a number of fields, although at first the devices need to be approved for a single medical purpose (one Iota has decided on but can’t disclose yet).

It’s a long road, all right, but at the end of it is the fulfillment of a promise straight out of sci-fi. It may be years before you have microscopic, ultrasound-powered doodads swimming around inside you, but that future is well on its way.

SpaceX’s futuristic Starship interplanetary craft may embody the golden age of sci-fi in more ways than one: in addition to (theoretically) taking passengers from planet to planet, it may sport a shiny stainless steel skin that makes it look like the pulp covers of old.

Founder and CEO Elon Musk teased the possibility in a picture posted to Twitter, captioned simply “Stainless Steel Starship.” To be clear, this isn’t a full-on spacecraft, just part of a test vehicle that the company plans to use during the short “hopper” flights in 2019 to evaluate various systems.

As with most Musk tweets, this kicked off a storm of speculation and argument in the Twitterverse.

The choice surprised many because for years, modern spaceflight has been dependent on advanced composite materials like carbon fiber, which combine desirable physical properties with low weight. When metal has been required, aluminum or titanium are much more common. While some launch components, like the upper stage of the Atlas 5 rocket, have liberally used steel, it’s definitely not an obvious choice for a craft like the Starship, which will have to deal with both deep space and repeated reentry.

As Musk pointed out in subsequent comments, however, stainless steel has some advantages versus other materials when at extremely hot or cold temperatures.

This is a special full-hardness steel alloy mentioned as being among the 300 series of high-strength, heat-resistant alloys — not the plentiful, pliable stuff we all have in our kitchens and buildings. Musk also mentioned another “superalloy” called SX500 that SpaceX’s metallurgists have developed for use in the Raptor engines that will power the vehicle.

So why stainless? It’s likely all about reentry.

Many craft and reusable stages that have to face the heat of entering the atmosphere at high speed use “ablative” heat shielding that disintegrates or breaks away in a controlled fashion, carrying heat away from the vehicle.

It’s unlikely this is a possibility for Starship, however, as replacing and repairing this material would necessitate downtime and crews wherever and whenever it lands, and the craft is meant to be (eventually) a quick-turnaround ship with maximum reusability. Heat shielding that reflects and survives is a better bet for that — but an enormous engineering problem.

Scott Manley put together a nice video illustrating some of these ideas and speculations in detail:

Musk said before of the Starship (then still called BFR) that “almost the entire time it is reentering, it’s just trying to brake, while distributing that force over the most area possible.” Reentry will probably look more like a Space Shuttle-esque glide than a Falcon 9 first stage’s ballistic descent and engine braking.

The switch to stainless steel has the pleasant side effect of making the craft look really cool — more in line with sci-fi books and comics than their readers perhaps ever thought to hope. Paint jobs would burn right off, Musk said:

You can’t expect it to stay shiny for long, though; it may be stainless, but like a pan you left on the stove, stainless steel can still scorch, and the bottom of the Starship will likely look pretty rough after a while. It’s all right — spacecraft developing a patina is a charming evolution.

Details are still few, and for all we know SpaceX could redesign the craft again based on how tests go. Next year will see the earliest hopper flights for Starship hardware and possibly the Super Heavy lower stage that will lift its great shiny bulk out of the lower atmosphere.

The technical documentation promised by Musk should arrive in March or April, but whether it will pertain solely to the test vehicle or give a glimpse at the craft SpaceX intends to send around the moon is anyone’s guess. At any rate you should expect more information to be spontaneously revealed before then at Musk’s discretion — or lack thereof.

Amazon this morning said its Alexa devices were among the holiday season’s best-sellers, particularly the Echo and Echo Dot. But the influx of new users setting up their devices for the first time on Christmas Day appeared to be more than Alexa could handle. The service crashed briefly on Christmas, as thousands of new Alexa device owners tried to connect their Echo to Amazon’s servers around the same time.

The Guardian first reported the Alexa outage, which began around 10 AM GMT and led existing Echo owners to complain they were unable to use their devices for regular tasks like playing music or smart home controls, for example.

Others said they were unable to set up their device, despite not having any other internet or home Wi-Fi issues, which seemed to point to a server-side outage.

Amazon’s Twitter account noted the issues were isolated to Europe, saying at 8:43 AM EST (1:43 PM GMT): “Over the past two hours some Echo devices in Europe have had intermittent connections.” The outage was resolved by the time the account had responded, meaning it had only lasted a couple of hours.

An Amazon spokesperson also confirmed the outage to TechCrunch.

“For a short period yesterday morning we had an issue that intermittently impacted some Alexa customers’ ability to interact with the service,” the spokesperson said. “The Alexa service is now operating normally.”

Amazon declined to offer details on what caused the outage, or explain how it was resolved. Likely, it was related to the increased number of requests. The Alexa app shot to the top of the App Store and Google Play on Christmas — another signal that points to a large number of first-time Echo owners setting up new devices on the holiday.

The website Down Detector also spotted troubles with Alexa that impacted Europe, with a peak of 2,183 reports coming in at the height of the outage. The reports then tapered off a couple of hours later.

This isn’t Alexa’s first outage by any means, nor even its first this year. The service can become unresponsive at times, either due to server issues or overloads. In March, for example, the voice service went down even while the Alexa mobile app still worked.

And in September, Alexa went down across Europe, apparently related to an AWS outage in Ireland. That was followed by a U.S. outage the following month, which led the assistant to respond to requests with “sorry, something went wrong.”

Europe is a growing market for Alexa, with Amazon having introduced its smart speaker to Italy and Spain this June. Alexa’s other international markets include the U.K., Australia, India, New Zealand, Germany, Japan and Ireland.

Researchers at the New Jersey Institute of Technology, while testing the “station keeping” functions of the glass knifefish, have created an augmented reality system that tricks the animal’s electric sensing organs in real time. The fish keeps itself hidden by moving inside of its various holes/homes and the researchers wanted to understand what kind of autonomous sensing functions it used to keep itself safe.

“What is most exciting is that this study has allowed us to explore feedback in ways that we have been dreaming about for over 10 years,” said Eric Fortune, associate professor at NJIT. “This is perhaps the first study where augmented reality has been used to probe, in real time, this fundamental process of movement-based active sensing, which nearly all animals use to perceive the environment around them.”

The fish isn’t wearing a headset, but instead the researchers have simulated the motion of a refuge waving in the water.

“We’ve known for a long time that these fish will follow the position of their refuge, but more recently we discovered that they generate small movements that reminded us of the tiny movements that are seen in human eyes,” said Fortune. “That led us to devise our augmented reality system and see if we could experimentally perturb the relationship between the sensory and motor systems of these fish without completely unlinking them. Until now, this was very hard to do.”

To create their test they put a fish inside a tube and synced the motion of the tube to the fish’s eyes. As the fish swam forward and backward, the researchers would watch to see what happened when the fish could see that it was directly effecting the motion of the refuge. When they synced the refuge to the motion of the fish, they were able to confirm that the fish could tell that the experience wasn’t “real” in a natural sense. In short, the fish knew it was in a virtual environment.

“It turns out the fish behave differently when the stimulus is controlled by the individual versus when the stimulus is played back to them,” said Fortune. “This experiment demonstrates that the phenomenon that we are observing is due to feedback the fish receives from its own movement. Essentially, the animal seems to know that it is controlling the sensory world around it.”

Whether or not the fish can play Job Simulator is still unclear.

“Our hope is that researchers will conduct similar experiments to learn more about vision in humans, which could give us valuable knowledge about our own neurobiology,” said Fortune. “At the same time, because animals continue to be so much better at vision and control of movement than any artificial system that has been devised, we think that engineers could take the data we’ve published and translate that into more powerful feedback control systems.”

A Juul is not a cigarette. It’s much easier than that. Through devilishly slick product design I’ll discuss here, the startup has massively lowered the barrier to getting hooked on nicotine. Juul has dismantled every deterrent to taking a puff.

The result is both a new $38 billion valuation thanks to a $12.8 billion investment from Marlboro cigarettes-maker Altria this week, and an explosion in popularity of vaping amongst teenagers and the rest of the population. Game recognize game, and Altria’s game is nicotine addiction. It knows it’s been one-upped by Juul’s tactics, so it’s hedged its own success by handing the startup over a tenth of the public corporation’s market cap in cash.

Juul argues it can help people switch from obviously dangerous smoking to supposedly healthier vaping. But in reality, the tiny aluminum device helps people switch from nothing to vaping… which can lead some to start smoking the real thing. A study found it causes more people to pick up cigarettes than put them down. It estimated that in 2015, 2,070 cigarette-smoking adults quit with help from vaping, but 168,000 teens and young adults who used e-cigarettes eventually started smoking real cigarettes daily.

How fast has Juul swept the nation? Nielsen says it controls 75 percent of the U.S. e-cigarette market, up from 27 percent in September last year. In the year since then, the CDC says the percentage of high school students who’ve used an e-cigarette in the last 30 days has grown 75 percent. That’s 3 million teens, or roughly 20 percent of all high school kids. CNBC reports that Juul’s 2018 revenue could be around $1.5 billion.

The health consequences aside, Juul makes it radically simple to pick up a lifelong vice. Parents, regulators and potential vapers need to understand why Juul works so well if they’ll have any hope of suppressing its temptations.

Shareable

It’s tough to try a cigarette for the first time. The heat and smoke burn your throat. The taste is harsh and overwhelming. The smell coats your fingers and clothes, marking you as smoker. There’s pressure to smoke a whole one lest you waste the tobacco. Even if you want to try a friend’s, they have to ignite one first. And unlike bigger box mod vaporizers where you customize the temperature and e-juice, Juul doesn’t make you look like some dorky hardcore vapelord.

Juul is much more gentle on your throat. The taste is more mild and can be masked with flavors. The vapor doesn’t stain you with a smell as quickly. You can try just a single puff from a friend’s at a bar or during a smoking break with no pressure to inhale more. The elegant, discrete form factor doesn’t brand you as a serious vape user. It’s casual. Yet the public gesture and clouds people exhale are still eye-catching enough to trigger the questions, “What’s that? Can I try?” There’s a whole other article to be written about how Juul memes and Instagram Stories that glamorized the nicotine dispensers contributed to the device’s spread.

And perhaps most insidiously, vaping seems healthier. A lifetime of anti-smoking ads and warning labels drilled the dangers into our heads. But how much harm could a little vapor do? Well, nicotine and other chemicals in the vapor can impair blood vessel dilation, increase arterial stiffness, increase blood pressure and heart rate and hurt the lungs by being toxic to alveolar macrophage. Even if it’s not as bad as cigarettes, vaping is still dangerous, and it doesn’t necessarily stop people from burning tobacco.

A study found only 10 percent of former smokers who turned to vaping had actually quit cigarettes after a year. My friend who had never smoked tells me he burns through a full Juul pod per day now. Someone got him to try a single puff at a nightclub. Soon he was asking for drags off of strangers’ Juuls. Then he bought one and never looked back. He’d been around cigarettes at parties his whole life but never got into them. Juul made it too effortless to resist. 

Concealable

Lighting up a cigarette is a garish activity prohibited in many places. Not so with discreetly sipping from a Juul.

Cigarettes often aren’t allowed to be smoked inside. Hiding it is no easy feat and can get you kicked out. You need to have a lighter and play with fire to get one started. They can get crushed or damp in your pocket. The burning tip makes them unruly in tight quarters, and the bud or falling ash can damage clothing and make a mess. You smoke a cigarette because you really want to smoke a cigarette.

Public establishments are still figuring out how to handle Juuls and other vaporizers. Many places that ban smoking don’t explicitly do the same for vaping. The less stinky vapor and more discreet motion makes it easy to hide. Beyond airplanes, you could probably play dumb and say you didn’t know the rules if you did get caught. The metal stick is hard to break. You won’t singe anyone. There’s no mess, need for an ashtray or holes in your jackets or couches.

As long as your battery is charged, there’s no need for extra equipment, and you won’t draw attention like with a lighter. Battery life is a major concern for heavy Juulers that smokers don’t have worry about, but I know people who now carry a giant portable charger just to keep their Juul alive. But there’s also a network effect that’s developing. Similar to iPhone cords, Juuls are becoming common enough that you can often conveniently borrow a battery stick or charger from another user. 

And again, the modular ability to take as few or as many puffs as you want lets you absent-mindedly Juul at any moment. At your desk, on the dance floor, as you drive or even in bed. A friend’s nieces and nephews say that they see fellow teens Juul in class by concealing it in the cuff of their sleeve. No kid would be so brazen as to try to smoke a cigarette in the middle of a math lesson.

Distributable

Gillette pioneered the brilliant razor and blade business model. Buy the sometimes-discounted razor, and you’re compelled to keep buying the expensive proprietary blades. Dollar Shave Club leveled up the strategy by offering a subscription that delivers the consumable blades to your door. Juul combines both with a product that’s physically addictive.

When you finish a pack of cigarettes, you could be done smoking. There’s nothing left. But with Juul you’ve still got the $35 battery pack when you finish vaping a pod. There’s a sunk cost fallacy goading you to keep buying the pods to get the most out of your investment and stay locked into the Juul ecosystem.

One of Juul’s sole virality disadvantages compared to cigarettes is that they’re not as ubiquitously available. Some stores that sells cigs just don’t carry them yet. But more and more shops are picking them up, which will continue with Altria’s help. And Juul offers an “auto-ship” delivery option that knocks $2 off the $16 pack of four pods so you don’t even have to think about buying more. Catch the urge to quit? Well you’ve got pods on the way so you might as well use them. Whether due to regulation or a lack of innovation, I couldn’t find subscription delivery options for traditional cigarettes.

And for minors that want to buy Juuls or Juul pods illegally, their tiny size makes them easy to smuggle and resell. A recent South Park episode featured warring syndicates of fourth-graders selling Juul pods to even younger kids.

Dishonorable

Juul co-founder James Monsees told the San Jose Mercury News that “The first phase is proving the value and creating a product that makes cigarettes obsolete.” But notice he didn’t say Juul wants to make nicotine obsolete or reduce the number of people addicted to it.

If Juul actually cared about fighting addiction, it’d offer a regimen for weaning yourself off of nicotine. Yet it doesn’t sell low-dose or no-dose pods that could help people quit entirely. In the U.S. it only sells 5 percent and 3 percent nicotine versions. It does make 1.7 percent pods for foreign markets like Israel, where that’s the maximum legal strengths, though refuses to sell them in the States. Along with taking over $12 billion from one of the largest cigarette companies, that makes the mission statement ring hollow.

Juul is the death stick business as usual, but strengthened by the product design and virality typically reserved for Apple and Facebook.

Bellabeat, the company behind a variety of health and wellness wearable devices aimed at women, is now selling its first smartwatch. The device, which is simply called “Time,” was announced earlier this month right in the midst of holiday shopping season. Like other fitness trackers, the watch is capable of basic tasks like counting your steps, tracking sleep patterns and reminding you to move. But unlike traditional smartwatches — which, aesthetically, are still very much just a screen on your wrist — the Time is designed to look like jewelry.

The hybrid device looks like a watch — albeit not a very expensive one.

It’s squarely in the range of fashion jewelry, with either silver or rose gold stainless steel finishes to choose from, and a minimalist watch face that forgoes complications like the date or the moon phase, for example. It even lacks a second hand.

That said, I prefer its cleaner look-and-feel to the gaudier smartwatches put out by brands like Michael Kors and Fossil. (Plus, there’s no Android Wear/Wear OS to contend with here.)

As an analog watch, it has both its pros and cons.

It’s designed to be hypoallergenic so as not to irritate those with sensitive skin, and it has some water resistance. (ATM grade 3, meaning it can withstand a vigorous hand washing and the rain. You can’t swim, bathe or dive with it.)

You also don’t have to charge it, which makes it feel more like a “real” watch than a gadget.

However, there’s a potential downside here, too — the coin cell battery only lasts “up to” six months. You’ll then need to use the tiny tool it ships with to replace the old battery with a new one.

Of course, some will see a user-replaceable battery as a perk. I don’t, but that’s a personal preference on my part.

I much prefer just dropping my Apple Watch onto a charger rather than having to keep up with a small watch tool, which can be easy to lose or misplace in the time between repairs. I’m also not a fan of having to unscrew tiny screws and then finding some sort of small, sharp object to pop out the battery. Perhaps that’s because I have a child with a dozen or so battery-operated toys. I’m constantly unscrewing things to replace batteries, and frankly I don’t need another.

In any event, among the watch’s better aspects is the fact that it packages up fitness and wellness tracking in a device that passes as a regular — and even fairly attractive — piece of fashion jewelry. The Time will go better with some of your outfits where you just don’t think the Apple Watch works — even with one of Apple’s fancier bands.

Of course, it’s not as seamless to use Time as the Apple Watch, which has the Apple platform advantage. (Or an Android smartwatch paired with an Android phone, for that matter.)

Instead, you have to sync your activity between the watch and the third-party Bellabeat app to view things like the steps taken or hours slept. You do so by tapping a sync button in the app and double-tapping on the watch face.

The app can also serve as way to keep up with other aspects of your health and wellness, including your hydration goals, stress, meditation time and your period.

The stress metrics are calculated for you, based on factors like activity levels, sleep quality, reproductive health and meditation over the past week. But hydration and menstruation have to be logged manually (*unless you’re using Bellabeat Spring — see below.)

The mediation tracking only calculates your progress through the app’s own selection of more than 30 included exercises. While it’s nice to have access to those resources included in the app, many people are already using popular meditation apps like Calm or Headspace. An “import” option for externally logged “mindful minutes” would have been nice here.

One of Time’s better features are its silent alarms and inactivity alerts. Instead of pings and loud noises, the watch more calmly reminds you of things with vibrations you configure. There are also included alarms for waking up, taking your vitamins, taking your contraception pill and another general alarm setting, each with their own toggle switches and settings.

There is something to be said for a quieter smartwatch, especially if stress levels are a concern. (There’s also something to be said for a device that’s built by a woman with the needs of women in mind. Remember how long it took for Apple to realize period tracking was a thing?)

That said, it’s unfortunately becoming harder for smaller device makers to compete with the Apple Watch, which has now moved into advanced areas with its Series 4 line, with sports, life-saving ECG and fall detection features, along with smarter workout detection (and yes, you can still swim with it), plus its ability to work with the broader iOS app ecosystem in a more native way.

But the Apple Watch is pricier at $399 and up for current models. Bellabeat’s Time, by comparison, is $179.

The Bellabeat mobile app will work with other Bellabeat products, including its wellness tracker Leaf (which can be worn as a bracelet, necklace, clip, etc.), and $59 smart water bottle, Spring.

Combined, the Spring and Time could be a good entry point into the world of fitness and wellness trackers for those who never felt that wearables and trackers were right for them. Bellabeat’s line is more of a lifestyle choice based just as much on looks as on tech, if not more so.

The question now is whether or not Bellabeat can carve out a big enough slice of the smartwatch market, which continues to be dominated by Apple, to sustain itself in the years ahead.

Bellabeat was a Y Combinator 2014 grad founded by female entrepreneur Urska Srsen, and has raised ~$19 million to date, according to Crunchbase. It previously sold products for expectant mothers, as well, but those have been phased out. Bellabeat declined to share any user metrics or revenue figures, when asked.

We will be holding a small event during CES in Las Vegas and we want to see you! We’re looking to meet some cool hardware and crypto startups, so the good folks at Work In Progress have opened up their space to us and 200 of you all to hold a meetup and pitch-off.

There are only 200 tickets, so if you want to come please pick one up ASAP. The meetup is open to everyone, so head over if you’d like to talk tech. You can pick up a ticket here.

If you’d like to pitch at the event I’ll be picking 10 companies that will have three minutes to pitch without slides. Because this is a hardware event I recommend bringing a few of your items to show off. If you’d like to pitch, fill this out and I will contact those who will be coming up on stage.

See you in Vegas!

There were countless gadgets released in 2018. It’s the end of the year, so Brian and I rounded up the best of the best and the worst of the worst.

Some where great! Like the Oculus Go. Or the Google Home Hub. But some were junk, like the revived Palm or PlayStation Classic.

CES 2019 is a few weeks away, where manufacturers will roll out most of their wares for the upcoming year. But most products will not be available for purchase for months. What follows is a list of the best and worst gadgets available going into 2019.

The Best

Google Home Hub

Google took its sweet time bringing an Echo Show competitor to market. When the Home Hub did finally arrive, however, the company lapped the competition. The smart screen splits the size difference between the Echo Spot and Show, with a form factor that fits in much more comfortably in most home decor.

Assistant still sports a much deeper knowledge base than Alexa, and the Hub offers one not so secret weapon: YouTube. Google’s video service is light years ahead of anything Amazon (or anyone, really) currently offers, and the competition shows no sign of catching up.

DJI Osmo Pocket

I wanted to dislike the Osmo Pocket. I mean, $349 for a gimbal with a built-in screen is pretty steep by any measure — especially given the fact that the drone maker has much cheaper and more professional options. After an afternoon with the Pocket, however, I was hooked.

The software takes a little getting used to, but once you’ve mastered it, you’re off to the races, using many of the same tricks you’ll find on the Mavic line. Time-lapse, FaceTrack and the 10 Story Mode templates are all impressive and can help novices capture compelling video from even the most mundane subject matter.

Oculus Go

The most recent wave of VR headsets has been split between two distinct categories. There are the high-end Rift and Vives on one side and the super-low-cost Daydreams and Gear VRs on the other. That leaves consumers in the unenviable position of choosing between emptying the bank account or opting for a sub-par experience.

Oculus’ Go headset arrived this year to split the difference. In a time when virtual reality seems at the tail end of its hype cycle, the $199 device offers the most compelling case for mainstreaming yet.

It’s a solid and financially accessible take on VR that shows that the category may still have a little life left in it yet.

Timbuk2 Never Check Expandable Backpack

Granted, it’s not a gadget per se, but the Never Check is the best backpack I’ve ever owned. I initially picked it up as part of a Gift Guide feature I was writing, and I’ve since totally fallen for the thing.

As someone who spends nearly half of his time on the road these days, the bag’s big volume and surprisingly slim profile have been a life saver. It’s followed me to a Hong Kong hostel and a Nigerian hotel, jammed full of all the tech I need to do my job.

It’s also unassuming enough to be your day to day bag. Just zip up one of those waterproof zippers to compress its footprint.

Happy Hacking Keyboard Professional 2

Like most nerds, I have more keyboards than friends. In 2018 I gave mechanical keyboards a chance. Now, at the end of the year, I’m typing on a Happy Hacking Keyboard Professional 2. It’s lovely.

This keyboard features Topre capacitive 45G switches. What does that mean? When typing, these switches provide a nice balance of smooth action and tactile feel. There are a handful of mechanical switches available, and after trying most of them, this switch feels the best to me. The Topre capacitive switch is available in a handful of keyboards, but I like the Happy Hacking Keyboard the best.

The HHK has been around in various forms since 1996, and this latest version retains a lot of the charm, including dip switches. Everyone loves dip switches. This version works well with Macs, has two USB ports and is compact enough someone could throw it into a bag. Starting just last month, the keyboard is available in the U.S. through Fujitsu, so buyers don’t have to deal with potentially shady importers.

The Worst

Palm

The Palm is the kind of device you really want to like. And I tried. Hell, I took the thing to Africa with me in hopes that I’d be able to give it some second life as an MP3 player. But it fell short even on that front.

This secondary smartphone is a device in search of a problem, appealing to an impossibly thin slice of consumer demographics. It’s definitely adorable, but the ideal consumer has to have the need and money for a second display, no smartwatch and an existing Verizon contract. Even then, the product has some glaring flaws, from more complex user issues to simple stupid things, like a lack of volume buttons.

It’s easy to forgive a lot with a fairly well-designed first-generation product, but it’s hard to see where the newly reborn company goes from here. Palm, meet face.

Red Hydrogen One

Where to start? How about the price? Red’s first foray into the smartphone space starts at $1,293 (or $1,595 if you want to upgrade your aluminum to titanium). That price will get you a middling phone with an admittedly fascinating gimmick.

After what seemed like years of teasers, the Hydrogen One finally appeared in October, sporting a big, metal design and Rambo-style serrated edges. The display’s the thing here, sporting a “nano-photonic” design that looks a bit like a moving version of those holographic baseball cards we had as kids.

I showed it to a number of folks during my testing period, and all found it initially interesting, then invariably asked “why?” I’m still having trouble coming up with the answer on that one. Oh, and a few told me they became a touch nauseous looking at it. Can’t win ’em all, I guess.

Facebook Portal

“Why?” is really the overarching question in all of these worst devices. It’s not as if the Portal was a bad product. The design of the thing is actually pretty solid — certainly it looks a lot nicer than the Echo Show. And while it was initially lacking in features, Facebook has made up for that a bit with a recent software update.

The heart of the question is more about what Portal brings to the table that the Echo Show or Google Home Hub don’t. It would have to be something pretty massive to justify bringing a Facebook-branded piece of hardware into one’s living room, especially in light of all of the privacy concerns the social media site has dealt with this year. There’s never been a great time for Facebook to launch a product like this, but somehow, now feels like the worst.

Portal delivers some neat tricks, including impressive camera tracking and AR stories, but it mostly feels like a tone-deaf PR nightmare.
