Tesla unveils a portable battery powerbank for mobile devices

The automaker has discreetly put online in its shop a portable battery “Powerbank” of 3350 mAh.

Unfortunately, it is already exhausted! The Tesla Powerbank portable battery has already found many takers, who bought it for $ 45. The manufacturer has not done much publicity. If it recently unveiled its novelties, an electric truck and a new Roadster, it did not even mention the existence of the battery.

Convenient, it incorporates Apple’s USB, microUSB and Lightning connections. Thus, it is possible to recharge the vast majority of mobile devices on the market, iOS or Android.

The battery itself is composed of a single 18650 cell of 3350 mAh. Of course there are alternatives but Tesla is also the design and we must admit that it is rather successful.

Remember that in 2015, Tesla had already unveiled a range of batteries for the home, including PowerWall.

 

Did you know that Apple deliberately slows down the iPhone performance?

In two complaints, Apple is accused of deceptive business practices because it deliberately slows down its iPhones. Cupertino argues that it is about saving the battery, but some customers of the brand see a limitation pushing users to buy a new iPhone.

Apple was recently forced to admit that it was deliberately slowing down its iPhone to spare components. The information is not new: the specialized hardware press reports these performance degradation for several years. This is the first time Apple has made an official statement on this.

Lithium-ion batteries are becoming less able to respond to peaks of activity in cold weather, when the battery is low or because it ages,” says Cupertino.

For so long the device went off without warning, “last year, we released a feature for the iPhone 6, iPhone 6S and iPhone SE designed to smooth peaks only when necessary, to prevent the unit from turning off suddenly”. A feature since extended to the iPhone 7.

The removable battery, solution to all problems

And what was to happen happened: in the days following this confirmation, two complaints were lodged, one in Illinois, the other in Chicago. And they could well turn into class action.

Apple is accused of deceptive marketing practices, since these slowdowns are made without the knowledge of the consumer, without it being informed of the underlying reason.

Therefore, the deliberate degradation of iPhone performance can be seen as an incentive to purchase a new smartphone, apparently more efficient. Hello planned obsolescence!

Especially since the only replacement of the battery would be enough to continue to use the old iPhone. But impossible for the common man to change the battery himself and out of warranty the replacement is charged 79 dollars.

48 Gbps Ultra-High Speed HDMI 2.1 cable to display 10K images

The New Ultra-High Speed HDMI 2.1 cable will be capable to display 10K images (10240 x 4320 pixels) with a bandwidth of 48 Gbit / s.

While 4K content is still far from being democratized, technology continues to advance. Thus, the HDMI Forum has just given the specifications of the new HDMI 2.1 standard.

In this case, it is thought to support resolutions up to 10K; to schematize, five times higher than Full HD.

Recall that 10K corresponds to resolutions of 10,240 x 4,320 pixels. This is what HDMI 2.1 offers at 120 Hz and with a bandwidth of 48 Gbit / s where the standard 2.0 offers “only” 18 Gbps. For this, it will require new cables dubbed “Ultra High Speed ​​HDMI“, backward compatible with the previous standards.

Dynamic HDR

At the same time, the HDMI Forum also announces that the 2.1 standard will support Dynamic HDR formats. This technology makes it possible to adapt the content, in particular the brightness and the color levels, in real time.

It is interesting to note that manufacturers are adopting HDR technology, such as Nvidia and AMD, which support the function in their latest GPU models. On the other hand, Dell has already introduced compatible displays, including the S2718D, and LG will unveil a monitor at the next #CES2018.

The best tips to buy your first DSLR camera

These are the best tips that will help you decide which is the best professional camera you should buy!

If you are a lover of photography, you have saved money and you are willing to buy your first camera, surely the question will arise on which one you should choose. With so many good options in the market, the choice can be a bit difficult, especially if you’re just starting out in the world of photography.

We have prepared the following guide for you, that will allow you to know the best tips to buy your first professional camera and that you feel comfortable with it.

What is the best option between a DSLR and a MILC?

DSLR cameras, also called DSLR, have been for years the best option when buying a professional camera. They are based on the same design as older film cameras that use a physical mirror inside the body of the camera to direct light to the viewfinder.

Not only the fact that SLRs have a large number of available objectives makes them the first option in mind of a photographer who will buy the camera, but also its ergonomics, the enormous quality that this method gives to others, and the fact that they maintain the same characteristics as regards the traditional reflex system.

However, market trends are changing, and in recent years mirrorless interchangeable lens cameras (also known as Mirrorless or MILC) have evolved much from their beginnings and are currently very popular. They use the same sensors and components as the DSLR, but with an electronic viewfinder and they are much smaller and lighter.

There is also a third group that are compact cameras, very popular in the past, and that are a good option if what we are looking for is a simple option to manage and much cheaper. However, we will talk about the latter on another occasion and in a much more specific way.

Deciding between a DSLR or a Mirrorless is, perhaps, the most important decision that one has to take when acquiring a camera, because there are many aspects to consider between them. For this, we are going to analyze some of them.

What are the characteristics that my new camera must have?

Canon professional camera EOS 7D buying tips

DSLR or DSLR cameras have much faster burst speeds, better battery life, have a tilting mirror system that brings light to the optical viewfinder to frame the image and a phase detection focusing system that allows you to have a fast and accurate autofocus.

They have a large number of accessories and a wide variety of lenses, but they are sturdy, large and heavy. For this reason, if what you want is a smaller camera that is easier to carry, you have to opt for the Mirrorless option.

The latter do not have a mirror system, the light passes directly to the sensor, giving us an image that has been processed by the sensor. In addition, they are smaller and lighter than DSLR, which makes them more portable. But at the same time, they do not have such a wide range of accessories and lenses.

Also, they do not have optical viewers, although the quality of the Live View is quite good and, in turn, have a slower contrast focus than the phase detection approach. The battery life is much shorter, have a very elegant design, support a higher ISO and have a greater sharpness.

We recommend you: Panasonic Lumix FZ300

Which manufacturer should I decide?

If you decide to buy a DSLR or SLR camera, you have to know that the brands that offer the best models are Canon and Nikon. Sony, Olympus and Pentax have acceptable DSLR models, but they are not as popular, so you will not get lenses and accessories as easily as the first ones.

Dslr camera buying tips - how to buy a professional camera

On the other hand, if you have decided on a Mirrorless you must surely choose between the models of Sony, Fujifilm and Olympus (who are currently leaders in that sector of the market). Although I must tell you that the differences you can find between each manufacturer are not very big and it all comes down to knowing each model better in detail so you can have a more accurate decision that best suits you.

Full-Frame or Crop Sensor?

What do we mean when we talk about these two terms? Well, the sensor is the heart of every digital camera and it is who really takes the pictures. In general, the larger the sensor, the better the photos will be, but the cameras will be much more expensive.

Among the DSLR cameras there are mainly two sizes of sensors: 35 mm (usually called Full Frame) and APS-C (clipping sensor). The Mirrorless come with Full Frame sensors, APS-C and other much smaller sensors. The difference between the sensors lies in the size of the sensor.

Thus, the full format, Full Frame offers a greater sensitive area than that offered by the APS-C sensors. Which means that they are capable of capturing a region of a higher scene. If you’re just starting, the recommendation is that you opt for a camera with APS-C sensor, which will give you excellent image quality and save you money by being cheaper.

More megapixels does not mean it’s a better camera

The number of megapixels of a camera is the number of points a camera is able to capture in a given scene. However, this does not necessarily mean that a larger number of pixels will result in a better camera or better photo quality.

The number of megapixels only gives you an idea of ​​the size of the photographs taken, not of the greater or lesser fidelity of the photograph with respect to the scene portrayed. The larger the photos are in pixels, the larger the size at which you can make prints without losing quality.

What you never have to forget is that without an adequate objective or lens, the quality of the photos will not be good and this has to be the most important detail in the camera you choose. The latest cameras that have come onto the market have the necessary megapixels you need.

It never hurts to consider buying a used camera

The cameras have a considerable duration in years. Many professional photographers have cameras that are up to six years old and have a high image quality.

In fact, the newer ones do not take better photos, but add new features such as adaptability to work in extreme situations, better burst rates, faster and more accurate autofocus, they can film movies, they come with Wi-Fi, etc.

That is why if you are just starting out in the world of photography and your budget is a bit tight, surely buying a used camera will be a good option. There are very good offers in this type of cameras and you just have to make sure they have the details that we have mentioned as essential.

Finally, we know that you have a lot to think about in order to make the right decision of which camera to buy. We have tried to cover some of the relevant points that will help you get one.

However, we believe that when deciding on a model or another what matters is what you are looking for and that it suits your needs.

We hope that you are satisfied with the purchase and please tell us in the comments below what model you chose and why?

Samsung Galaxy A8 (2018) smartphone on render images

A 18: 9 format display like on the Galaxy S8 (Plus), a fingerprint sensor and a speaker in an unusual place: Render images show the Galaxy A8 (2018), which Samsung will presumably present in January at CES.

Not only for the Galaxy S9 (Plus), Samsung apparently plans a spring break in the new year. Even before the new models of the flagship series, the South Koreans are likely to introduce new devices of the mid-range Galaxy A family.

Insiders expect that Samsung will show the Galaxy A8 (Plus) in January at the Consumer Electronics Show (CES) in Las Vegas.

The new Samsung smartphone is the first A-series model to have a 6-inch Super AMOLED display in oblong 18: 9 format.

The fingerprint sensor on the Galaxy A8 (2018) will sit directly under the camera, given the narrow, flat edges on the back of the smartphone. A dual-camera with 16 megapixels or 8 megapixel resolution, the device, however, only the front – at the back is based on advance information a single 16-megapixel camera with f / 1.7 aperture.

2018 Galaxy A8’s Design

The Next Samsung Galaxy A8 2018 releasing this Jan worldwide

The Dutch fan blog Galaxy Club has now released render images of the Samsung Galaxy A8 in a matching protective case. The Samsung smartphone is shown in three different color options. At the bottom edge of the model, which has been moved by an aluminum frame, there is a USB-C connection and a jack socket for wired headphones.

Also, the unusual position of the speaker on the right side above the power button can be seen. Not to be seen are the under-the-hood features of the device : the Exynos chipset 7885, a 4 GB or 6 GB in the Plus model memory, 64 GB of internal memory and a 3,100 mAh or 3,500 mAh strong battery.

In addition the memory size and battery capacity of the Galaxy A8 (2018) and Galaxy A8 Plus (2018) still differ by the display size of each other. The smaller smartphone model is said to offer a 5.7-inch super AMOLED screen. The display resolution should be format-appropriate 2,220 x 1,080 pixels for both devices.

Report: No Bixby Voice on Galaxy A8 (2018)

Samsung will deliver the new Galaxy A8 (Plus) apparently still with Android 7.1 Nougat and not yet with the latest Google operating system. An update to Android 8 Oreo should then be submitted later.

The assistant service Bixby, developed by Samsung, will be pre-installed, for which the manufacturer claims that the voice control will be activated in German next year. A dedicated button for working with Artificial Intelligence service is probably not on the devices. According to Electronic Times, Bixby Voice will not be available on the Galaxy A8 (Plus) for 2018.

Should Samsung actually present the new A-series at the CES, we will keep you updated about the latest news and updates of this amazing phone.

Self-driving cars: Why in the future the interior design is must

When cars control themselves, people have time for other things. That’s why designers now design offices, sleeping capsules and luxury wheeled suites. This will change not only driving but also business models.

Pia greets you as soon as you drop into one of the chairs. It makes sure that the right radio station is running, and knows which lighting you like because it recognizes one on your smartphone. It activates the massage function when the neck is tense – and anyone who freezes recommends the seat heating.

Pia is the voice of an artificial intelligence designed to make your stay in the autonomous car as comfortable as possible. At least when it comes to Audi boss designer Marc Lichte, who has designed Pia.

self-propelled cars BMW cars for 2021

It will not be long before driverless vehicles are on the road. BMW, for example, plans to build the first self-propelled cars from 2021 onwards. The industry is facing one of its biggest challenges:

how does the car of the future have to be? Which requirements should it satisfy?

According to estimates by the consulting firm PwC, traditional manufacturers and suppliers, who are currently collecting 70 percent of the profits in the industry, will have to settle for only half of what can be earned with cars by 2030.

The reason for this are providers of networked technologies and digital services, which push themselves between the manufacturer and the customer – just as the chauffeur service Uber demonstrates with its pick-up function via smartphone wipe.

Only those who understand how to set the right accents in terms of technology, comfort and design will have a chance of winning in this new mobility game.

What will be important in the future is shown by Marc Lichte with the concept car Audi Aicon. The vehicle is controlled with artificial intelligence and introduces itself, as I said, with a female voice, as Pia. And Pia can do a lot.

Self driving cars Why in the future the interior design is must

It picks up its (smartphone) users on its own doorstep, illuminates them with a built-in drone on boarding and alighting – and is otherwise designed as a kind of smart living room on wheels that adapts to the preferences and needs of travelers. “We have designed the Audi Aicon as a luxury vehicle of the future, which is designed especially for travel on long journeys,” emphasizes Lichte.

Four interior modes in a car

Not just Audi, just about all car manufacturers, work on the question of what the car looks like when it drives alone one day. Volkswagen has developed a self-driving minibus with its VW Sedric, which can be used as an office or meeting room.

Yanfeng Automotive Interiors, a Chinese-Irish supplier of automotive interiors, recently presented a concept vehicle that can switch between the four Drive, Lounge, Family and Meeting modes – depending on the setting, the seats move to or from each other, and in family mode, it slides in Origami table in the middle.

Volkswagen VW Sedric self driving mini bus

BMW has already shown a car that can be controlled via a hologram, that is, via control elements projected into the room. Renault has designed with Symbioz a lounge-like luxury sedan: The seats can be rotated like a living room to each other; light falls through a glass dome roof; Seats in gray fabric, copper-colored fittings and a pull-out marble table spread a homely atmosphere.

Rolling offices, moving luxury suites or sleeping capsules on wheels: everything is possible. If cars no longer need a steering wheel, are also so sure that seat belts are superfluous, and with the electric mobility even the space for the internal combustion engine is eliminated – then the interior can be designed as free as never before. For car designers, these are golden, creative times.

Meet Ryan, the six-year-old boy who made 11M USD this year reviewing toys on YouTube

The children of now want to be Youtubers, and when they do, many parents want to earn money

Forbes has published its annual list with the youtubers that have earned the most money in 2017. All the owners have been taken by DanTDM to dethrone PewDiePie as the one with the most income now, but hidden in the list we have a child of only six years that is making a millionaire doing reviews of toys.

This is Ryan’s ToysReview, who at six years old already amasses more than 10 million subscribers that make him earn 11 million dollars a year before taxes. This child is the protagonist of a channel run by his family in which he is seen opening and using all kinds of toys, which has earned him to reach the eighth place in the list of Forbes.

Ryan’s case is the most notable of the growing tendency to see youtubers children as a replacement for the actors or children’s singers of the past. Some cases that are not exempt from controversy, since there are those who see in this type of channels examples of child exploitation with parents wanting to take advantage of their children.

The Verge spoke with the family last year, and revealed details such as that her mother decided to leave work to dedicate herself to the channel full time. Not surprisingly, according to this medium, the 10 million subscribers are providing income of one million dollars a month only in advertising.

Ryan ToysReview began in March 2015, but it was in July of that same year when it reached virality with a video in which it was seen opening a giant surprise egg and playing with the dozens of toys that are inside it. This video to date has already managed to surpass 800 million visits.

Currently in the channel we can see reviews of new toys, food products and other types of entertainment videos in which some video clip is included. All while watching the young Ryan’s reactions, and the voice of his mother listening in the background and asking questions about the products in front of him.

The rest of the protagonists of the list

As we have said, the list of Forbes this year is led by youtuber Daniel Middleton ( DanTDM ), who at 26 years old and with more than 16 million subscribers has pocketed 16.5 million dollars in 2017. It is followed by Evan Fong ( VanossGaming ), who receives close to 15.5 million dollars with at least 22 million subscribers.

In third place on the list we have Dude Perfect surpassing 14 million dollars, followed by Logan Paul and Mark Fischbach ( Markiplier ) with 12.5 million each. Until the sixth place has fallen Felix Kjellberg (PewDiePie), the ever controversial youtuber whose channel pockets 12 million dollars.

The seventh place is occupied by Jake Paul, one of the most popular creators of Vine, and who has obtained 11.5 million dollars in 2017 according to Forbes. Followed by the aforementioned Ryan ToysReview with 11 million dollars, Smosh with the same amount, and finally Lilly Singh ( IISuperwomanll ) that in 2017 “only” has obtained 10.5 million dollars.

Everything about Bluetooth 5.0, what mobile phones have it and what it is for

Right now the biggest unknowns about Bluetooth 5.0 are what mobile phones have it and what it’s for. And it is not for less, since it is a new technology that, for now, few have implemented, so its use has not yet been extended, and users are not used to it.

As we will explain below, Bluetooth 5.0 has a number of advantages that will make you want your smartphone to incorporate this new communication protocol . Although, if you make memory, you will remember that we already tell you some aspects of Bluetooth 5.0 when we talk about the Samsung Galaxy S8, which is the first smartphone that has it.

All about Bluetooth 5.0.

Bluetooth 5.0 usage and review

In order to understand the changes that are going to happen, we are going to tell you all about Bluetooth 5.0, what mobile phones have Bluetooth 5.0 and what exactly it is for. Although, if your mobile already has it, it is possible that something you discovered for yourself.

What is Bluetooth 5.0?

This section is the easiest to solve, since Blueetooth 5.0 is, simply, the fifth version of this popular wireless communication protocol that, traditionally, has served both to transfer files between two devices, as well as to transmit audio to a loudspeaker, or to get the most out of a smartwatch for example.

Historically, despite its slowness in some situations, it has been a widely used wireless transmission method. In fact, surely in your car you have a hands-free device, or a portable speaker that works with Bluetooth.

Now, this Bluetooth 5.0 has improved the performance of the previous version, enabling a data transfer twice as fast, and an eight times greater bandwidth. That is, you will be able to transfer data eight times as fast twice as fast.

In addition, Bluetooth 5.0 increases the distance range of the signal four times, so you can separate more of your accessories when they are connected.

What is Bluetooth 5.0 for?

Obviously, Bluetooth 5.0 serves the same purpose as previous versions. However, it has certain peculiarities, since this Bluetooth 5.0 can, for example, transmit audio to two different speakers at the same time, something ideal for mounting a good audio system at home. Although, of course, it is not the best option for interiors, but for exteriors.

As we have said before, Bluetooth 5.0 increases four times the distance of the signal, something that will be ideal when using drones, since it will not be necessary to be at such a close distance. This triggers the autonomy that these devices can have at the distance level, of course.

what is bluetooth 5.0 and what is it used for

In addition, since Bluetooth 5.0 allows a higher file transfer speed, you can leave the cables aside to transfer files to your computer. And best of all: you will not have to lose quality when transmitting photos via WhatsApp, you can transfer the complete files without losing time, which is what happens now when you try to transmit a file via Bluetooth.

Which phones have Bluetooth 5.0?

At the moment, there are few smartphones that have the famous Bluetooth 5.0. As you know, the Samsung Galaxy S8 laureate was the first to incorporate this new technology, and then, it has been the Sony Xperia XZ Premium that has followed his steps, in addition to other smartphones such as the LG V30. In short, almost any recent high-end, will have this technology, so if you want to use this technology, you know what you have to do.

When the Bluetooth 5.0 is going to be extended?

Since this technology was introduced, it is available for integration into all the manufacturers that make up the Bluetooth Special Interest Group, which are more than 30,000. This figure, as you can deduce, includes both smartphone manufacturers and brands dedicated to audio or accessories.

Therefore, the normal thing would be that at the end of this year 2017 we saw a good amount of smartphones and accessories, such as hands-free, speakers or smartwatches that have Bluetooth 5.0 connectivity.
