Portable Robotic Printer

This printer is outfitted for our day to day life. It has a rechargable battery and an on/off switch. It connects directly to smartphones andto the PCs, and allows the user to print on any size piece of paper.

Few things in life have frustrated me as much as printers. The small mobile printer is super-compact and most importantly easy to use. It connects via Wi-Fi and works with any computer, tablet or smartphone. In order to print, you simply align the Zuta with the paper by placing it at the top left corner of the page. Once it's set up, you can use the Zuta app to print whatever documents you'd like. The robotic printer chugs from left to right and, depending on what you're printing, can take awhile.

The wireless printer works for about an hour and is rechargeable via micro USB. Users can print on all sizes of paper and it works without drivers and can print from Macs, PCs iOS and Android.

 The size is just 10.2 centimeters in diameter  is a big selling point for the product. It is aimed at users who only need a printer infrequently. The fact that it also works with smartphones and tablets is a big deal too. More often than not, to print documents from phone more than laptop. It is small enough to fit into the palm of your hand, the four-inch wireless device makes it easy to produce images on the go.

The printer rolls back and forth over a piece of paper, until the on-screen image is recreated in about a minute. This Robotic Printer integrates with an app, which enables it to print what you see on your phone.

The battery just lasts about an hour, but it is rechargeable via a micro USB. It is compatible with Android, iOS and Windows. One ink cartridge can print about 100 pages.

Galileo Robotic Motion Control iphone

Robotic Motion Control iphone

This is an must have gadget for your iPhone, especially if you are into photography. If there's one accessory for the iPhone that has been breathlessly anticipated by a lot of photographers and videographers, it's the Motrr Galileo robotic iPhone mount. There are also white or black models, just in case you're fussy about making sure your motion-control mount matches your iPhone.

This test device was one of the Bluetooth models. It's a rather tiny device a squat cylinder about 3.25" in diameter and just two inches tall. There's a micro-USB port on one side for charging, one LED for battery status on the bottom, and several "cups" that are used to ensure a tight fit of your iPhone or iPod touch so it doesn't fall out during a photo session. The first thing you need to do is go out to the App Store and pick up the Motrr app. 

To link a Galileo-enabled app with the device, you simply twist the bottom and top parts of the mount to send a pairing signal to the iPhone. That's it. With the Sphere app, there was a special item under the "hamburger" button for linking the Galileo mount and starting the photography. What happened next was incredible: the Galileo began whirring and moving, stopping to take photos at precise intervals. Within a very short amount of time. The spherical image of my kitchen to navigate around.

The Motrr Galileo robotic mount is perfect for the iPhone or iPod touch photographer/videographer who desires precise control of camera movement. While there still aren't a lot of apps available offering support for the mount.

It is very precise and extremely quiet, perfect for filming video. Unique design offers almost spherical coverage of any scene through 360° pan and tilt. Can be mounted on any standard tripod. Not that many apps support the device at this point, particular the Bluetooth version of the Galileo.

 The iPhone videographer who wants a better way of controlling pan and tilt automatically during filming, the photographer who is working on time lapse photographs, or (coming soon) anyone who wants to control where someone else's device is pointed during a video call.

DIETSENSOR

DIETSENSOR

Manually logging in meals can be exaspirating, we know. That’s why we worked hard to develop this sleek, snappy, little app just for you. By scanning your food, it’ll take 10 times fewer clicks to log a food than with other manual input methods.

Do you need better control of your nutrition? Our app reads the spectrometric scans from your SciO scanner and provides accurate analysis of your homogeneous food or beverage. Spectrometry is the process we use to identify the chemical makeup of your food. This even takes into account specific cooking and additive ingredients, like cooking oil. We believe that if nutrition tracking isn’t accurate, it isn’t helpful.

DietSensor gives accurate results with any homogeneous food, even with homemade dishes and beverages that do not have a nutritional label. So you can stay balanced, even when it’s home cooked.


For those times when you need to input non-homogeneous foods, you’ll have access to our extensive, ever-expanding food database with over 600,000 food items from 50 countries (in 19 languages!) with ultrafast bar-code scanning.

DietSensor innovative progression chart gives you comprehensive information on carbs, fat protein, calories, and alcohol levels to provide customized nutrition goals. Stay on target by getting tailored-to-YOU feedback on the quantity and quality of your food. Recurring diet setbacks. Weight fluctuations. Low hydration levels. DietSensor helps you recognize and understand your own habit patterns and advises you accordingly.

DietSensor is in partnership with Consumer physics, creators of the first, pocket, wifi-connected molecular sensor. SCiO uses something called near infrared spectroscopy to determine the chemical makeup of food and drink. Each type of molecule in a food vibrates in its own unique way, and these vibrations interact with light to create a unique, optical signature. In brief, spectrometers analyze what is in a substance based on how its molecules interact with light

. The SCiO shines a light on the food or beverage of your choice when you click a button. Then, a tiny optical sensor (the spectrometer) collects the light reflected from the food sample. It breaks the reflected light down to its spectrum, or the array of varying wavelengths.

DietSensor builds spectrometric models that translate the resulted information into something really useful – a calorie count and the percentage of carbohydrates, fat, and protein contained in your food. This is all quickly sent and clearly displayed on the DietSensor app on your smartphone.

We are ever-expanding our database to give you the widest range of food and drink possible, so you can always get a clear readout, even for those healthy muffins you just pulled out of the oven.

Paper Battery

Paper Battery

A paper battery is a flexible, ultra-thin energy storage and production device formed by combining carbon nano-tube s with a conventional sheet of cellulose-based paper. A paper battery acts as both a high-energy battery and super capacitor , combining two components that are separate in traditional electronics. This combination allows the battery to provide both long-term, steady power production and bursts of energy. Non-toxic, flexible paper batteries have the potential to power the next generation of electronics, medical devices and hybrid vehicles, allowing for radical new designs and medical technologies.

It is basically a device which can act both as a capacitor and as a battery. It is a flexible, light weight device made up of carbon nano tubes emboldened on paper (cellulose). It is basically formed by combination of cellulose with carbon nano-tubes. It consists of infusion of carbon nano-tubes with paper consisting of an ionic liquid as an electrolyte.

Paper battery can actually prove beneficial for applications where portability and size is the main requirement. Modern day electronic equipments like smart cards, digital watches facilitate the requirement of thin batteries which are long lasting and non toxic. Wearable Computers – One of the latest real time examples of wearable computers is Google Glass. 

It actually is a normal spectacle with an optical head mounted display and Glass is a computer in the form of a pair of eyeglasses and includes an optical head-mounted display which allows the user to use a smart phone. It can also be used for low power devices like calculators, wrist watches and wireless communication devices like mouse, Bluetooth headphones, keypads etc.

Paper batteries may be folded, cut or otherwise shaped for different applications without any loss of integrity or efficiency . Cutting one in half halves its energy production. Stacking them multiplies power output. Early prototypes of the device are able to produce 2.5 volt s of electricity from a sample the size of a postage stamp.

The devices are formed by combining cellulose with an infusion of aligned carbon nano-tubes that are each approximately one millionth of a centimeter thick. The carbon is what gives the batteries their black color. These tiny filaments act like the electrode s found in a traditional battery, conducting electricity when the paper comes into contact with an ionic liquid solution. Ionic liquids contain no water, which means that there is nothing to freeze or evaporate in extreme environmental conditions. As a result, paper batteries can function between -75 and 150 degrees Celsius.

One method of manufacture, developed by scientists at Rensselaer Polytechnic Institute and MIT, begins with growing the nano-tubes on a silicon substrate and then impregnating the gaps in the matrix with cellulose. Once the matrix has dried, the material can be peeled off of the substrate, exposing one end of the carbon nano-tubes to act as an electrode . When two sheets are combined, with the cellulose sides facing inwards, a super-capacitor is formed that can be activated by the addition of the ionic liquid. This liquid acts as an electrolyte and may include salt-laden solutions like human blood, sweat or urine. The high cellulose content (over 90%) and lack of toxic chemicals in paper batteries makes the device both bio compatible and environmentally friendly, especially when compared to the traditional lithium ion battery used in many present-day electronic devices and laptops.

As a result of the potentially transformative applications in electronics, aerospace, hybrid vehicles and medical science, however, numerous companies and organizations are pursuing the development of paper batteries.Specialized paper batteries could act as power sources for any number of devices implanted in humans and animals, including RFID tags, cosmetics, drug-delivery systems and pacemakers. A capacitor introduced into an organism could be implanted fully dry and then be gradually exposed to bodily fluids over time to generate voltage.

Working:

Internal operation of paper batteries is similar to that of conventional batteries with each battery generating about 1.5V. If one can recall traditional batteries work in the manner where positive charged particles called ions and negative charged particles called electrons move between positive electrodes called anode and negative electrode called cathode.

Current flows as electrons flow from anode to the cathode through the conductor, since the electrolyte is an insulator and doesn’t provide a free path for electrons to travel.

Similarly in some paper batteries, carbon nanotubes act as cathode, the metal is the anode and paper is the separator. Chemical reaction between metal and electrolyte results in production of ions whereas chemical reaction between carbon and electrolyte results in production of electrons. These electrons flow from the cathode to the anode through the external circuit.

Given below are three ways to create paper batteries:

1. The first method involves fabricating zinc and manganese dioxide based cathode and anode. The batteries are printed onto paper using standard silkscreen printing press. This paper is infused with aligned carbon nano-tubes which are used as electrode. This paper is dipped in a solution of ionic liquid which acts as the electrolyte.

2. The second method is a bit complex and involves growing nano-tubes on a silicon substrate. The gaps in the matrix are then filled with cellulose and once the matrix is dried, the combination of cellulose and nano-tubes is peeled off. Thus sheets of paper consisting of layers of carbon nano-tubes are created. Two such sheets are combined together to form a super capacitor with a ionic liquid like human blood, sweat or urine being used an electrolyte.

3. The third is a simple method and can be constructed in a laboratory. It involves spreading a specially formulated ink of carbon nano tubes over a rectangular sheet of paper coated with an ionic solution. A thin film of lithium is then laminated on the other side of the paper. Aluminium rods are then connected to carry current between the two electrodes.

Six Important reasons How Paper Batteries useful:

1.Paper batteries have long lasting time. 

2.They are non toxic as they do not involve harmful chemical reactions. 

3.They are flexible and can be folded or cut without any effect on their efficiency. This is because of the fact that they are made up of materials like cellulose and carbon nano-tubes which have high tensile strength.

4.They are disposable as they are made up of cellulose which is bio degradable and non toxic. They can be used in harsh climate conditions like heat and cold. This is because the electrolyte does not involve water which makes the battery operate in the range of -73 to 149 degree Celsius.

5.They utilize carbon nano-tubes, which are one of the most highly efficient conductors of electricity.

Sony HMZ-T2 Personal 3D Viewer

World's first wearable personal 3D viewer

Sony launched the so called world’s first wearable 3D TV in India for Rs.69,900. The HMZ-T2 personal 3D viewer is a head-mounting device which has HD 2D and 3D personal display with win OLED screens.

The last among the many gadgets released by Sony on October 11, 2012 is the personal 3D viewer. This device is named as 3D Viewer HMZ-T2 and Sony has priced it at Rs.69,990. This sci-fi looking gadget is already available for pre-order at Sony Stores and they will be out during the Diwali season.

The Personal 3D viewer comes equipped with a HDMIU cable which can be connected to any device that has an HDMI port. Sony has made some changes as well from their earlier version; HMZ-T1. The built in ear buds have made way from regular 3.5 mm audio out jack. This change makes it easier for the user.

Once put on, the user looks like he walked right out of a science fiction movie. These glasses are not at all a disappointment when it comes with 3D images and brilliant sound quality. The 3D images that one views with this camera are not disappointing at all. The two individual OLED screens in the glasses allow the user to experience smooth transition between 2D and 3D content. The sound quality through these glasses is also quite impressive. But there is a drawback with the headphoens; since it is tiny the user must make sure he is in a very quiet environment.

The Sony HMZ-T2 Personal 3D Viewer is the second iteration of what Sony had initially created as a concept product. Designed as a way of looking into the future of home entertainment the device is Sony's answer to the awkward truth that 3D in the home still isn't perfect.Using two tiny OLED screens, the HMZ-T2 is able to create a 'perfect' 3D image without any of the eye-based confusion that can still take place using passive or active 3D technology.

These are claims that shouldn't be taken lightly, not only does the HMZ-T2 cost as much as a high-end TV, but it also limits viewing in that only one person can see the image. Of course, if that image happens to appear the size of an IMAX screen then things begin to make sense.

SIZE AND BUILD

With an almost identical look and feel to the original Personal 3D Viewer the HMZ-T2 has clearly taken its design cues from the world of Tron looking about as futuristic as you can get. With a plastic body and rubber headband it's not too heavy either coming in at a reasonable 330g. All the controls are sensibly arranged along the bottom while the now interchangeable headphone jack has been bafflingly placed inside the eye cavities resulting in a tangle of wires before you've even turned it on.

Where the HMZ-T2 fails is in how you actually wear it. Available with a series of rubber inserts that help to block outside light out, one wonders why these actually aren't a permanent fixture. Instead you have to individually pop each part of the 'blinkers' resulting in something that is less than stable adding to the overall feeling that perhaps you're still using a prototype.

SETUP

Taking this approach resulted in a completely painless setup. There's a box for HDMI input/output and power, the HMZ-T2 then uses a separate cable, which runs to the headset itself.

The wire is more than long enough for pretty much any living room. Because it's a single HDMI you can plug in almost any input from a Blu-ray player, your Sky HD box, Xbox 360 or Sony PS3 with the only downside being that it is just a single input so you will have to disconnect everytime you want to switch between formats.

PICTURE QUALITY

The headsets features two small OLED displays each of which has a resolution of 1,280 x 720 pixels. Yes you read correctly, that's NOT Full-HD. Does it matter? The only way to answer that question is by breaking it into two parts; gaming and films. Treat the HMZ-T2 as a gaming device and you'll be treated to a completely original gaming experience, well until the Oculus Rift is finally released.

With both the Xbox 360 and the PS3 maxing out at 720p the images you see are not only huge (The T2 creates a virtual screen size of 750-inches) but also clear. Fast response times along with the virtual 5,1 surround sound both contribute to create an immersive gaming experience that you simply won't find anywhere else. We spent a weekend playing Bioshock Infinite and felt a palpable sense of disappointment when we reverted back to a conventional TV.

Watching regular 2D films are where the chinks begin to show. Because the output is only 720p and the viewer has been designed for 3D viewing it immediately becomes clear that what you're seeing isn't the full Blu-ray experience. Instead fast moving images can become blurry and picture quality is noticeably reduced. The rubber attachments are an annoying design flaw while the fact that it's not Full-HD is regrettable. Add to that a price tag that could make you weep and what you have is a brilliantly engineered, but still not fully practical piece of the future.

Nura Headphones

Nura Headphones

Headphones that measure and adjust to your hearing

The combination in-ear and over-the-ear Nura headphones measure the wearer’s personal frequency sensitivity to offer an optimized music experience.

The Nura headphones are equipped with a microphone able to detect a sound as it enters and returns from the ear, allowing the device to determine the inner ear’s response to sound via an adaptation of OAE (otoacoustic emission) testing. The process takes about thirty seconds, with no interaction required by the wearer. Besides offering better sound quality, the headphones also help protect the user from high volumes.

Nura is a new headphone that integrates unique soundwave technology to automatically measure your hearing (from the outer ear all the way to the brain) and adapt music perfectly to you. In order for headphones to deliver the right sound, they must be matched to the listener. Nura even recognizes you when you put them on.

There isn't another set of headphones out there that combines neuroscience, acoustics and deep hearing in this way. And when we tested the products at a recent demo we found the resulting sound to be a substantial improvement.

The intimacy of the vocals, the rumbling of the bass, the heartbeat of the drums, and every single note of the churning lead guitar was distinct, perfectly balanced, and rocking.

Did you know that your hearing is as unique as your fingerprint, your face and your voice? Each of us has different sensitivities to different frequencies of sound. This means the same pair of headphones sound different for each person.

How do you choose the right pair of headphones when we all hear differently? It’s really confusing because sound and hearing are very hard to objectively self-assess. How do you know what you’re missing? Audiophiles are skilled at the art, but this takes them years of experience. It’s a rewarding journey, but it is time consuming and very expensive. Nura empowers everyone who loves music to find their perfect sound automatically.

Just like every human face and voice are unique, so too is the structure of everyone’s inner ear. These variations in anatomy result in us hearing sound differently. There’s a very wide range in our sensitivities to different frequencies.

Nura uses a microphone to know exactly what sound went in, and also uses the same microphone to listen to the faint sounds that return from the ear. This makes Nura very different from any other type of calibration. It actually knows the response of the inner ear. The inner ear detection is performed using an adaption of otoacoustic emission which is an amazing phenomenon well known in biology.

The sound that is produced by our ears and detected by our headphones’ internal microphone is encoded with information about how well you actually heard the sound that went in. Nura headphones connect to the lightning/usb port of your smartphone. You press go, and they sweep through a bunch of tones for about 30 seconds. At the same time, they listen to the sounds your ear is making. By processing these signals it works out how well specific frequencies of sound got through to your brain. Once they know this, they sonically mould to match your ears perfectly and provide rich, balanced sound for you.

The technology combines deep hearing and neuroscience, psychoacoustics, signal processing and acoustics.  The first time you put them on your head, they’ll measure your hearing a process that takes about 30 seconds. Nura headphones actually know you. Any time you put them on, Nura will recognize you in less than two seconds. Once Nura identifies you, they load your profile. Any music you listen to no matter the app will be optimized for your hearing, so you can hear every note perfectly.

DEEPEST BASE AND CLEAREST SOUNDS

Everyone has a different experience when trying new headphones. Some sound tinny and lack bass, others have too much bass which drowns out the detail. The acoustic separation of Nura’s design allows for the deepest bass and clearest tones. The over-ear cup delivers bass you can feel through your skin. The earbud prevents the bass from drowning out the detail and delivers crystal clear mid and high notes directly into your ear. Your brain combines the sensations into a fully immersive experience.

KEY FEATURES

Automatically measures and adapts to your hearing in 30 seconds
Customizes sound so you can hear every note perfectly
Allows listeners to jump right into yhe shoes of an audiophile who has spent years finding the right headphones
Double speaker drives deliver the deepest bass and clearest tones, bringing you closer to the action.
Two way isolation which means no noise in and no sound out. Nura headphones are perfectly silent.

EyeLock Myris

Forget Fingerprints: EyeLock Myris Brings Eye Scanning to Devices

The myris is computer mouse-size device that scans your eye. You plug it into the USB port on your computer, tablet or some other device. Pick it up, flip it over, look at it, and the sensor will immediately scan your eye to verify your identity.

Myris is a sleek handheld iris scanner, brings biometric security to home computers. The device plugs into a USB port and takes a split-second video of both eyes, scanning more than 240 points in each. A government-grade encrypted digital signature syncs with passwords stored on Myris, and never on your desktop. Once it verifies a match, it automatically signs the user into accounts through a browser extension. Since no two irises are alike, the chance of a false positive is less than one in two trillion.

Once your eye has been scanned and recorded, Eye Lock's software acts as a password manager. When it's time to log in somewhere, you can just look at the scanner, and the software will use your iris to unlock the password of whatever service you're trying to access. The myris is compatible with Windows PCs, Macs and even Chrome books. It supports up to five different users.

Myris provides unparalleled security, is portable, lightweight and is as easy as looking in a mirror. Use myris to quickly and easily enroll users for Eye Lock's access control products or to grant users access to corporate domain environments within seconds—users never have to type their username and password again. On the back end, administrators can set passwords as complex as they like and once myris is linked, they can forget them. Use myris for enrollment, directory authentication or to secure workstations, high-value transactions, critical databases and information systems for enterprises large and small.

Eye Lock uses video, uses video, not still pictures, to capture an image of your eyes, and delivers throughputs of up to 50 people per minute. No two human irises are alike not in twins, nor even on the same person. False Accept Rate of 1 in 1.5 million for a single eye.Eye Lock generates a unique encrypted code of each iris. Then to authenticate your ID, it matches the encrypted code with your eyes. The scanners themselves simply aren't designed to receive data from a file rather than a live scan. So even if a hypothetical hacker got your scan, they couldn't do anything with it.

New Flagship

New Flagship in China, Forms VR Company

It's no secret that Taiwanese smartphone manufacturer HTC has been going through tough times in the past few years, struggling to compete against both established names in the business and Chinese upstarts like Lenovo, Huawei, and Xiaomi. Its recent virtual reality efforts, in the form of the Vive VR headset built in collaboration with Valve, have however garnered critical acclaim. It is in this scenario that HTC is reported by Taiwanese media to be considering spinning off its VR division.


Focus Taiwan reports that HTC has managed to sell only 251 units of the HTC 10 in China during the pre-order period that began with Tmall and Jingdong Mall on April 25. The report attributes the low demand to HTC's decision to introduce the Snapdragon 652 SoC-powered variant of the HTC 10 in China, known as the HTC 10 Lifestyle, managing to alienate potential customers.

The same publication in a separate report says HTC has confirmed it has set up a new company for development of VR technology. HTC is said to have issued the statement as a response to other local media reports that the Taiwanese firm had formed the VR company late last year. It did not confirm whether it was considering spinning off the company, as local media also reported. 

 The new VR company when spun off will reportedly be controlled entirely by HTC Chairwoman Cher Wang. It currently operates in several domains as per government data cited by the report, including "the sale of computer equipment, information software, electronics material and precision machinery, and telecom equipment development, as well as online retail sales." The report adds the new company is also involved in international trade and warehousing business.

The identical e-book in a separate file says HTC has confirmed it has installation a new company for improvement of VR technology. HTC is said to have issued the statement as a response to different nearby media reports that the Taiwanese firm had fashioned the VR company overdue final year. It did not verify whether it become thinking about spinning off the organization, as nearby media also reported.

Highlights:

1.  Only 251 HTC 10 units were reportedly sold during the pre-order period. 
2. HTC reportedly confirmed if it has formed a new VR company. 
3. HTC however didn't confirm its plans to spin off the VR firm.

HOVERBOARD

HOVERBOARD

A hoverboard is a fictional levitating board used for personal transportation. Whether hoverboards are this year’s Tickle Me Elmo or the beginning of a true movement  is yet to be seen. Either way, they’re among the most discussed gadgets this holiday season and much as in the similarly trendy field of selfie sticks, figuring out which one to buy can be quite confusing. We researched these self-balancing, two-wheeled scooters for more than ten hours and rode three for more than twenty hours. After all that, we can’t pick any one model as the best because they all work similarly—and many even use the same technology inside. But we can give you some advice on what to look for when shopping and we can suggest a model that meets our criteria for a safe buy.

Our goal was to determine what sort of differences exist between models that appear to be largely identical on the surface—and sometimes sell at vastly different prices. Ultimately we discovered that we prefer riding inexpensive copycat models over a real one that costs Rs60,000 more because the hardware controls on the cheap hoverboards are easier to master. Our general advice is to choose an inexpensive hoverboard with a good warranty and responsive customer service to back it up.

After poring through dozens of product listings looking for models that fit those criteria, we tested several hoverboards and found them to be very similar in design and performance. However, the Swagway X1 is one of the only hoverboards sold by a company with a customer service department that actually replied to our requests for assistance—important because it’s likely indicative of how responsive the company will be to customer support requests. A dedicated learning mode makes the Swagway easier to start on than the others. We felt more comfortable going faster on it than on other models too. And it has a UL-certified charger, which not all competitors do, helping to assuage fears that it might burn down your house. If you must buy a hoverboard soon, it’s what we’d get.

If the Swagway goes out of stock or its price increases dramatically, the MonoRover R2 is an acceptable option. If you’re shopping around, keep in mind that—as we explain below—if a model looks identical to the Swagway and MonoRover, it probably is. If you find a similar model in the Rs 24,000 to Rs 30,000 price range, and it has good reviews, it’s probably safe, though we can’t guarantee that you’ll get a UL-listed charger, or that something inside isn’t slightly different. We do recommend confirming that the company has a US presence you might even try contacting the company, as we did for this guide, to see if you get a response.

No, they don’t actually hoverboard is the most commonly used term for these devices—partly because there’s no agreed-upon name for this class of product. You’ll see them called self-balancing scooters, motorized personal transporters, two-wheeled smart electric drifting boards, endless amalgamations of those terms, or just various brand names. All of that makes it difficult for you to find what you’re looking for without direction. We’ll stick with hoverboard here for simplicity.

Hoverboards aren’t likely to replace your car, your bike, or the bus as a daily form of transit—at least not if you need to commute over anything more than a couple of miles of smoothly paved surfaces. They have limited range (less than 10 miles on flat roads) and don’t move very quickly (the fastest model we tested maxes out at about 10 miles an hour). But they are a lot of fun. While a lot of people may criticize lazy hoverboard riders for gliding instead of walking, know that constantly keeping your balance takes some leg muscles. It’s far from a workout, but you may feel the burn, especially after a long ride.

Getting used to riding a hoverboard takes at least a few minutes—for some people, longer. (We suggest wearing a helmet and maybe having a friend walking behind, ready to catch you if you fall.) Once you get the hang of it, though, it’s much like riding a bike: You rarely think about it when you’re doing it. To go forward, you subtly tilt both feet forward; to turn, you simply apply a bit of pressure on the footpad opposite of the direction you want to go. The hardest part is getting on and off, because the board will start to move a little as soon as you put weight on it. Your best bet is to hold on to something as you mount and dismount, at least at first. The Swagway’s learning mode makes this task a little easier—the hoverboard is less sensitive with this mode enabled, so it’s more stable when you step on.As for safety, a hoverboard’s small wheels and lack of handlebars do compromise its stability when you’re riding over irregular terrain. It’s fine indoors or on smooth pavement, but you should prepare for challenges when going over the bumps, cracks, and rough surfaces you regularly encounter on a street or sidewalk.

They’re extremely hard to ride over even the smallest sidewalk cracks and gentlest curb slopes, and topography of any kind presents a real challenge.Before you try to commute on a hoverboard, we suggest checking with local laws. As of December 2015, they’re illegal or banned on New York City sidewalks, British streets, and flights, as well as in the Cleveland Cavaliers locker room. If you happen to get in any trouble, be polite and respectful—there’s a good chance the police will be more entertained than upset.Even if your city allows hoverboards on streets or sidewalks, you should also consider whether you’ll be a hazard to those around you when you’re riding. It’s tough to navigate a crowded sidewalk or shopping mall without bumping into people and running over toes.

Unfortunately, it’s difficult to know which models are safe—even well-known brands may cut corners by using inexpensive components that lack safety certification. In December 2015, we spoke to John Drengenberg, consumer safety director (and an engineer) for UL, about hoverboard safety concerns. At that time, UL had not yet tested any hoverboards, but Drengenberg was able to provide information about the UL certification process that remains useful for anyone shopping for a hoverboard. We continue to recommend avoiding budget-price hoverboards from unknown companies, and instead buying from companies with a US presence and responsive customer support.

UL certifies some finished products, such as vacuum cleaners, as whole units, but it also tests and lists individual components within products for electrical safety and fire risk. The charger will have the UL seal printed on its exterior, so you can easily verify this certification. Batteries however are more difficult to verify unless you take the device apart to find the UL seal on the battery itself.

However, even if a particular hoverboard’s battery and charger are UL listed, that doesn’t mean every other component inside is. The wiring may be of poor quality or use a risky design.If you’re unsure whether you have a hoverboard with UL-listed components, your best bet is to contact the manufacturer and ask for verification. In our interview, Drengenberg also suggested a few safety precautions every hoverboard owner can take. Don’t overcharge the battery—unplug the hoverboard once the battery is full—and don’t leave a hoverboard charging overnight or unattended. Make sure to use only the provided charger. And just in case something does go wrong, store the board away from combustible materials, especially while charging.

The manufacturing of hoverboards is such a twisted web that it’s impossible to know exactly who is making what, which brands are copying which, or who is telling the truth. And more than curiosity is on the line. Inventist, maker of the Hovertrax, claims to hold the patent on the hoverboard. They’re all the same. The designs may vary slightly—sometimes the faux hubcaps are shaped in Mercedes-like triangles, sometimes there are five or six spokes—but like painting tiger stripes on your kitty cat, nobody’s getting fooled here. Perhaps one factory sells boards to another. Perhaps one factory sells parts to another. Perhaps both factories buy parts or just boxes from a third factory.

with a small platform in the middle for your feet and a wheel on each side. The MonoRover and Swagway models are nearly identical, with only minor aesthetic differences such as slightly different curves over the wheel wells and different trim designs on the rubber foot-pads and the wheels.

The Hovertrax, on the other hand, looks like a more-refined piece of hardware. It’s a little smaller in every dimension (for example, 20½ inches across for the Hovertrax, compared with 22½ inches for the MonoRover and Swagway), and while the cheaper options look as if they came out of the same factory, the Hovertrax is obviously of different manufacturing lineage. All three are fairly heavy.

Because it’s difficult to tell what really goes into a given hoverboard, or even who actually makes it, we relied solely on subjective testing in our evaluations. We rode around an apartment, around a co-working space, down the street, and in a brew pub. We wanted to see if any of the boards were easier or harder to ride, or if any of them felt significantly faster or safer.

To put it simply: In our real-world tests, we found no huge differences in performance or behavior among the hoverboards, but we did end up preferring one of the models over the others.The narrower body of the Inventist Hovertrax makes the whole thing feel tighter—a little cramped—and it’s slower to turn from a standing position. In addition, its wheels lack any sort of tread, unlike with the other two hoverboards, which means the Hovertrax will be a little less forgiving over rough terrain. Even though it’s the most expensive model, and it may have inspired all the rest, we liked riding this one the least.

Hoverboards are toys. They’re fancy toys, and they’re fun, but that’s all they are. If you want to buy one, know that you could end up spending several thousands of rupees on an unregulated product with little quality assurance that may be illegal to ride in public in your jurisdiction.

Sphericam 2

Sphericam 2, the 4K 360º Video Camera 

The camera is about the size of a tennis ball, and has six built-in 4K  lenses to capture 360-degree video at 60fps.Sphericam 2 will also have WiFi, allowing you to live stream video to desktop or mobile devices.WiFi, allowing you to live stream video to desktop or mobile devices. Sphericam 2 is a spherical, 360º camera that allows you to capture absolutely everything around you in high resolution without any blind spots. You can watch the resulting videos on a VR Headset (like Oculus Rift, Samsung Gear VR or Google Cardboard) or on your iPad, tablet, PC or mobile phone.

Most cinematic VR creation attempts so far have been, well, less real and more virtual. Think blind spots, uneven stitching and mismatched white balance from unsynchronised sensors. There just aren't many people who want to go through the months of training required to operate 6 sports cameras stuck together, and the tremendous amount of tricky post processing that is needed to make such footage watchable.

A mini miracle that is no bigger than a tennis ball, Sphericam 2 is by far the best 360 degree video camera out there. Six cameras work seamlessly together to capture the world around you in stunning 4K resolution. In other words, you can capture great looking VR video content straight out of the box.

Sphericam 2 turns heads even before it’s turned on. Its breathtaking crystalline shape has been sculpted from anodized aluminum, letting you give it tough love during your adventures. And with a host of mounting options, there are many ways to hold (and behold) this camera. So whether it’s happening behind your back, under your feet or over your head, it’s all happening on your Sphericam.

With WiFi and streaming baked right in, viewing and sharing content on your smartphone and 

 desktop is a breeze. Our mobile app allows you to start/stop recording, monitor the view, while recording, transfer, view, edit and spread instant VR-love.

SPECIFICATIONS:

It is made up of Anodized Aluminum with 68mm diameter and weight less than 400 grams,the number of mounting points are eight. the micro USB port,Aytomatic Stabilization,GPS and live streaming available in Sphericam 2. It can record upto 60 to 90 minutes with four microphones and six cameras

File formats and Quality

Pro quality:Six individual videos, up to 60FPS in Cinema DNG, up to 2.4 gigabits per second bit rate total (300 megabytes per second) using the fastest type of memory card (Sandisk Extreme Pro). At 30FPS, it is entirely lossless. At 60FPS, it is slightly lossy, but in practical terms, you will still have as much freedom as possible in post production for color grading.

High quality compression:Six individual videos, compressed in H.264 (in an mp4 file) up to 600 megabits per second (100 Mbit/sec per camera).

Real time stitching resolution/quality:One single stitched panoramic video written to the internal memory of the camera in real time. We are aiming to deliver at least 30FPS at 4096x2048 resolution, in 10 bit color, with at least 600 megabits per second bit rate.

Live Streaming resolution/quality:Using a micro USB to Ethernet adapter, it will be possible to stream either 6 unstitched videos, or a single stitched panoramic video, at a bitrate of up to 100Mbps.
