Wireless (Bluetooth) in-ear audio monitor

Wireless in-ear audio monitor is a  wireless Bluetooth module and the module are housed in different capsules. The AF 100W is super lightweight, yet provide at least 5 hours of playback  time. And if  in case you need more than 5 hours of playback, you can use a ‘Quick Charge’ option.  This will have  it recharged within 20 minutes. This game-changer is made for those on the move. With great studio- quality  sound and a  sweat-protective design.

Originally, Australian headphone specialist Audiofly launches its first Bluetooth wireless earphones. The AF100W wireless in-ear monitor is tiny and light, yet, according to the manufacturer, provides “studio quality”.

Audiofly specializes in headphones. This Australian company is also selling its products through an European website. So, the existing in-ear and ear-ear headphones are now complemented with two Bluetooth wireless earphones. We shall review the AF56W  and AF100W here.wireless in-ear audio monitor

The AF56W is the wireless version of the AF56.  Audiofly’s most popular ordinary earphones with 13mm dynamic drivers. The slightly more expensive AF100W is stated by the manufacturer an “entry level wireless IEM”. In other words, wireless in-ear monitor. A dual-microphone micro driver. According to the manufacturer,  it provides better audio quality.  Thanks for the support to aptX codec.


The Audiofly AF100W tabs weigh only 13 gram.  So, you are comfortable with your ears and also thanks to the various included interchangeable eartips . Now, you can make them fit perfectly in your transition. The thin but reinforced nylon cable connects both earings. It has a block of control buttons on one side, it hang behind your head and tighten with a loop so that they fit perfectly.

You use everything with three buttons.  You can use those to turn on, connect Bluetooth, control the sound level, take and end calls, flip through tracks, and turn the microphone off temporarily (mute function). Everything is clearly explained in the manual provided.

These earphones are waterproof according to the IPX-4 specifications. The small drivers with neodymium magnet have a sensitivity of 107 dB at 1 kHz. This is a dynamic range between 20 and 20 kHz and an impedance of 16 ohms. The battery lasts four to five hours and has a standby time of 200 hours. She is fully charged in one hour and ten minutes.

Audiofly delivers a sturdy carry case that safely stores the AF100W,. Also, supplies USB charging cable and possibly the additional ‘ear tips’ for on-the-go.

Wireless in-ear audio monitor performance

The AF100W is very light and comfortable. The difference between left and right is clearly indicated on the tabs. The control panel block is located on the left rear. The three keys are embossed and you can operate blindly after any exercise. The specified battery and charging times correspond to our test response.

Sound quality is of course very subjective,. But these earphones sound clear and clear. Especially, if your playback device supports the better aptX bluetooth codec. However, these earphones do not play very hard, but that is not safe at all. Basses sound very pure.

The handsfree function works well. The received phone is ready and clear. But some conversation partners noted that the sound quality on their part was not always optimal.

Much also depends on whether you are in or out of a conversation and how much wind there is. The microphone has no function to filter wind noise.


AF56W  costs – € 99.99/ $ 119.34
AF100W costs- € 129.99/ $ 155.15

The Audiofly AF100W are well-fitting,  easy to use wireless headset. It has a good, albeit soft sound quality. This really comes by its own as your playback device supports Bluetooth APTX better codec.

Charge batteries through wifi from distance

Charge batteries through wifi, is an article where I have mentioned the background and invention process of charging batteries through wifi. The whole concept is discussed below:

Ikola Tesla  was disliked by the cables. He imagined and worked for a world in which they were not necessary.  Neither to communicate nor to transmit the energy. The first part of his dream has been fulfilled: there are radio, television, mobile telephony and Wi-Fi networks to prove it. The second part has become more pleasing. But begins to give satisfaction in the form of mats that recharge mobile and systems that feed from the waves of television or mobile.

The next advance in wireless energy has been achieved. That is the system to charge batteries through wifi. Interestingly, thanks to a system designed for communication: the wifi used by most households. A team of researchers from the University of Washington in Seattle (USA) has used a router to charge remote batteries. At the moment they have managed to power devices. Such as those using small appliances and remote controls (nickel-metal hydride batteries). Also, the button cells of the watches (small lithium-ion batteries). The magazine  MIT Technological Review  collects in an article the study, with an ambitious title:  “To feed the next billions of devices with the Wi-Fi ”

The concept of charging batteries through wifi

The system presented there is named PoWiFi (English acronym for “feed through wifi”). It operates at distances up to 8.5 meters. To achieve this. The researchers created a system that collects the energy from the wifi and continuously supplies it to the batteries.

The researchers presume that their achievement is compatible with the usual use of Wi-Fi . Also, it “does not significantly compromise its performance” to connect devices to the Net and to each other. However, for the Radio communication professor at the Polytechnic University of Madrid, José Manuel Riera , this would only be possible in “houses isolated and distant from one another”. Such as those of residential areas of the United States. But, not so much in apartments and floors in which many Europeans live,. Just by the interference of the connection with those of the neighbors.

“When we are not using the Internet, our router only uses 1% of the transmission time. They are disconnections of milliseconds that take advantage of other wireless networks to transmit, “says Riera. The use to supply power, however, requires the router to transmit energy continuously.” In a high usage environment, such as a university or a company, could not be applied “, illustrates the professor.

How does it work?

Unlike the devices that use the television and mobile phone frequencies, this system works with frequencies of the band ISMC (which includes Wi-Fi, but also Bluetooth and ZigBee ). US and European legislation does not limit it’s use to communications. Therefore, could also be used to power small devices, according to the authors.

However, power limitations in Europe (100 milliwatts) and the US (up to one watt, under certain conditions) are very far from what is needed to charge a smartphone. A smartphone needs 4 or 5 volts. To charge your battery for this system, you would have to emit a power a million times greater.

In addition, the waves emitted by a router are broadcasted in all directions (it is precisely the quality that allows them to use devices to connect devices located in various places of a house). But that dispersion plays against the power they are able to transmit.

In spite of the inconvenience, in the opinion of the professor of Electronic Engineering of the Polytechnic University of Valencia, José Sánchez-Dehesa, the investigation is “a significant advance” to keep fed all type of low consumption sensors. Such as those used in home automation and other internet applications. In fact, the study is completed with two new devices . A camera and a temperature sensor – that feed perfectly through the new system. Tesla’s house would have fitted in well.

Thank you all for reading my article ‘Charge batteries through wifi from distance’. Hopefully this new system will overcome all the set backs and present use more comfortable and efficient charging for our devices.

One Plus 5 : dual camera with longer battery life

OnePlus 5 with a major concentration on dual camera with longer battery life has left behind months of rumors and leaks. Before he is born he is already a cult smart phone, but will not reach any store. OnePlus, its manufacturer, maintains one of its founding principles, they only sell by Internet. The new model arrives at a price slightly higher than the norm of this brand and exceeds for the first time the border of 450 dollars or euros. It comes in two models, for $ 479 or 499 euros, with 64 gigabytes of internal memory and six gigabytes of RAM. For $ 539 or 559 euros it rises to 128 storage and eight RAM.

Kyle Kiang, World Marketing Director, met with El Pais in San Francisco a few days before the launch to explain the details of this expected device. The first thing he did was justify the price, the most controversial point: “In each new model we raise the quality. Consequently, it does the price because we offer more. We think it’s still a great option for that price”-  Kyle Kiang during the One Plus 5 exhibition.

One Plus 5

Since its first mobile, OnePlus has been characterized by competing with the most powerful mobiles for almost half price. They continue to stand up and in many respects, are the best option. But this time the price is around 70% of what their competitors cost. Continue reading One Plus 5 : dual camera with longer battery life

Olympus Tough: 4K photo & movie camera for adventure

Olympus launches a compact, portable digital camera called ‘Olympus Tough’ , that can withstand a push. The Tough! TG-5 is resistant to all weather conditions and has a 12MP sensor that can also record 4K videos.

In this article I will describe the attributes and distinctive characteristics of this camera:

The Olympus Tough! TG-5 is the successor to the rugged TG-4. Like its predecessor, this photo and movie camera is intended for adventurers and athletes who need a camera that can bump into all weather conditions.

Opposite the TG-4, the sensor and imaging chip were renewed while maintaining the super bright 25-100mm (35mm eq.) Lens. Remarkably, the TG-5 has a lower resolution cmos sensor: 12MP versus 16MP at the older TG-4.

Olympus Tough

But Olympus says that the image quality goes on in a wider range of light conditions on the windshield, thanks to the backlight of the CMOS sensor and the latest TruePic VIII image processor (same as in the previously tested DiskIdee Olympus OM-D E-M1 Mark II system camera ). Also, the TG-5 has a wider dynamic range than its predecessor.

The lens now has a double glazing that prevents them from following extreme temperature shifts. The TG-5 can shoot at 4K at 30fps and in Full HD at 120fps for slow motion videos.

The TG-5 adds the temperature to the field sensor system, including GPS, compass and manometer. This data is transferable along with photos and videos via Wi-Fi to the free Olympus OI-Track app.

The camera is also easier to operate, for example, when wearing gloves. This allows you to set important features using a handy dial. The “Pro Capture” feature allows you to select the best recording from a series.

The Olympus Tough! TG-5 camera is waterproof up to 15m, shock resistant to 2.1m, pressure-resistant up to 100kg and frost resistant to -10 ° C.a.

There are various accessories available for this rugged camera, ranging from a flash diffuser and fish eye converter, to a sports holder and an underwater housing that can capture photos and videos to a depth of 45m.

The Olympus Tough! TG-5 camera costs € 479 or $566.24.

Thanks a lot for your time.  I hope you have enjoyed reading this article.

solar energy ‘surpasses all forecasts and expectations’


Solar energy ‘continues to surpass all forecasts and expectations. It stands at 6 cents kilowatt-hour. In 2011, the US Department of Energy launched the SunShot Initiative, which sought to drastically reduce photo voltaic energy prices by 2020. This week, the National Renewable Energy Laboratory (NREL) has confirmed that 85 % of 2020 targets . Among them the most important is the ‘price’.


Today, in Kansas City (the place that is taken as the average reference in the United States because it has the average number of hours of sunlight in the country) kilowatt-hour has been placed at 6 cents. Therefore, without government subsidies that reduce the cost of the panels even more. In fact, this figure was calculated taking into account real cases and market prices .



Photovoltaic Energy

solar energy

The Photo voltaic energy is the natural resource that, through the application of technology, can be exploited industrially. The term also refers to the ability to transform or put something into motion.

It is known as photo voltaic energy. Therefore, the type of electricity (electric energy) that is obtained directly from the rays of the sun or solar energy. Thanks to the quantum photo-detection of a device. The photo voltaic energy allows to produce electricity for distribution networks, to supply isolated houses and to feed all type of apparatuses.

Root the mobile: so you can customize it to measure

Root the mobile: so you can customize it to measure’- in this article, I am going to tell you what rooting is for. Rooting is a process that offers more freedom to the user for doing things in the Operating System. But is complex and involves many risks.

Root the mobile, means:

Rooting is the process of gaining total access to everything in the operating system and those permissions allow you to change it all. Root, can be called the superuser. Our Android devices use Linux permissions and file-system ownership. We are an user when we log in and we are allowed to do certain things according to our user permissions. Root is also an user. The difference is the root user (superuser) has total access to do anything to any particular file at any place in the system. For an example, uninstalling application forced on us by the developers or the sellers. Also, things we are unwilling to do can put our Android programs in a corrupted state. But, when we are doing things with superuser permissions, we have the power to change anything.

Process of Rooting

The mobiles leave the factory with an installed configuration. Also, have an operating system in a combination that the manufacturer has tailor made and with great care. In theory, this marriage is best suited to exploit to the maximum what the terminal offers. But, this is defended Apple layer with its iPhone,. It is an armored mobile with limited configuration options by the user. On the other hand Android, when it comes to customizing the platform, it gives something more of a broad sleeve to the user. However, both platforms touch the same ceiling in the customization range: the one determined by the manufacturer.

However, the bravest can penetrate into warmer waters by rooting. A process by which superuser permissions are acquired to access the deepest part of the mobile and configure it at will. Thanks to this process, we can remove programs from the system. Also, we can install customized versions of the operating system (known as ROMS). The concept of rooting essentially refers to Android devices. Although iPhone owners will find some comfort in the familiar jailbreak. But, both are not exactly the same. The big question is why rooter a device?

Functions on demand

Those who defend rooting explain that they get more personalization of the equipment eliminating unnecessary programs and adding functions à la carte. Carrying out this procedure allows the user to remove from the game known as bloatware or software that arrives preinstalled in the device. Already  occupying space and resources. This is one of the most critical that has been done by certain manufacturers and operators. Those who make a root will be able to choose better performance of the processor. They can force the machinery in certain situations or to slow it down saving battery. This procedure also allows to make total backups of the device. Nevertheless, for lovers of the exclusive, an extreme personalization of the device.

However, this procedure is risky.  On the one hand, it is most likely that the warranty of the terminal is lost and on the other, it runs the risk of damaging it definitively. In addition, it is not a procedure available to anyone: “We lose security”, explains Fernando Álvarez del Vayo, editor in chief of El Androide Libre . He also points out that this is a practice in disuse. “As Google improves its system and devices its features the need to make root access to an Android mobile, or a tablet, it decreases a lot.” The root it would recommend, in this way, advanced users and driven by a real need to do so. Something increasingly less given the evolution of Android devices.

Mobile applications you had not imagined

A mobile is much more than a cold bright display apparatus. This is our faithful companion in the day that device that never leaves you if your battery begins to threaten us and has to resort to saving mode. It accompanies us through thick and thin. In the event in which they have left us planted and we turn to slide so melancholy thumb Instagram. Also in most intimate moments, which took the library of games, while we sat on something that many call throne?


Besides all this, a mobile phone can serve many more uses and have decided to collect them. After discussing it in writing no doubt these would be the five uses, you could give your smartphone in addition to those already frequent. What’s more, sure you list any of the sounds of something.
