Drone Under the Sea

Drone development is now increasingly sophisticated. Not only the action in the air, there are even drones that are created to act under the sea, like this one drone.

Named BIKI, an artificial drone company from China, Robosea can be a friend for the traveler who is fond of photographing and enjoying the beauty of the underwater. The shape is also unique, which is made to resemble a fish.

If seen while swimming in the ocean maybe the traveler thinks this is a real fish. When viewed closely, this is not a real fish but a bionic fish robot that is used as an underwater drone.

Drone BIKI is claimed to be the world’s first bionic underwater drone. Looking at the new innovation product funding site, Kickstarter, Thursday (5/25/2017), BIKI helps the traveler to take pictures under the sea more freely.

Turn on BIKI, put in the water and the traveler can manage the movements with easy to use remote control. No need to install waterproof casing first as underwater camera in general.

BIKI is also designed to be able to regulate balance and avoid objects that block their path. Movement is also nimble like a real fish, with a tail that move while swimming.

The ability to record images no doubt. BIKI equipped with 150 degrees wide angle lens, can record 4K video, 32 GB internal memory and battery that can last up to about 2 hours.

BIKI can swim and record images to a depth of 59 meters. Swim too fast, so you can diving with BIKI and capture the exciting moments and natural beauty under the sea.

Traveler who want to try to use BIKI must be patient because it has not been mass produced. Still opened pre-order on the Kickstarter website with prices starting from USD 549

Apple AirPods Review: Real or Gimmick?

Apple recently introduced its very first version of wireless earbuds. This accessory was launched together with the iPhone 7 as well as the iPhone 7 Plus. They are essentially in-ear AirPods that are wireless. They are truly wire-fee and make connections only via Bluetooth. The important question is that are they a glimpse into a wire-free future or just another design disaster? That is the big question that this review will diligently seek to answer.

Features

The following are some of the interesting features that the Apple AirPods have to offer the innovation-hungry tech market:

Design

The AirPods have a design that is quite simple and are white in color. They typically sit in the opening of ears with nothing more than a mere small rod protruding outside the ear and down the face of the user. The outer rod of the AirPods is sensitive to touch and allows the user to either pause music or interact with Siri. The design is amazing in both appearance and functionality, a cool

Battery

The AirPods do not have connectors as they are charged only via a charging case that is provided in the iPhone box on purchase. It has a convenient size as it similar to dental floss box, this makes it easy to carry it in the pocket or a small bag. The battery can last up to 5 hours of listening time from just a single charge and 24 hours of listening time from the charging case. This is a good battery life by all standards.

Connecting to music

The AirPods easily connect to Apple devices. All one has to do is to put them and their charging case near the phone and they connect. Once the AirPods are connected to a single device, they will be available to all of the user’s Apple devices through iCloud where it will automatically detect the type of device that music is being listened from.

One AirPod or two

When they are both put in the ears music starts playing automatically. However, when one is taken out of the ear the music stops playing in stereo and switches to mono. If both AirPods are removed from the ear, the music is paused until the time they are once again picked and put in the ears.

No buttons

Siri can easily be accessed by double-tapping the AirPods so as to make music selection and control what plays, adjusting the volume, checking the battery life or other necessary Siri tasks. Buttons are non-existent whatsoever on these futuristic AirPods. This is one of the reasons why this product is going to be a success because of simplicity.

Speech

The AirPods each have an extra accelerometer that is able to detect if the user is speaking. The accelerometer allows a pair of microphones that are formed by a beam to maintain focus on the voice of the user. They proceed to filter out noise from the external environment to facilitate the faster and easier detection of the user’s voice.

Pros

The Apple AirPods have a number of advantages that interested clients stand to enjoy. The main ones include the following:

  • They are easy to use as they are simply put in the ears and can be used to listen.
  • The AirPods seamlessly switch from a phone call on the user’s Apple devices to music being played on an Ipad, Mac or even an Apple Watch.
  • They do not fall out of the ears when running and can therefore be used when exercising vigorously. However, it should be noted that this applicable only for short distances.

Cons

The Apple AirPods have a few disadvantages. The notable ones are as follows:

  • The light weight and small sized AirPods can easily get lost. Apple has not provided a lost and found feature that can be used to signal track them in case of such an eventuality.

Conclusion

The Apple AirPods review above clearly shows that opinion is polarized especially with regard to their design. However, the fact that the earphones can be lost due to their small size and light weight is not desirable. The AirPods are exemplary in connections. Similarly, they are smart with regard to sound isolation for voice calls and functionality. The Apple AirPods review above is proof enough that Apple is undoubtedly setting a significant benchmark in relation to a future that is wire-free.

The battery calibration

What the battery calibration?

Batteries included hardware function to save power. With the battery, devices like cell phones and laptops may have the power to perform its functions. The battery also has the capacity. The battery capacity can not be seen directly. The operating system takes a certain software, such as drivers, to read the battery level so that we can see how the remaining battery level. Ranging from 0% to 100%.

Need some Calibatrion

In theory, with the passage of time then the software will not be for accurately displays the percentage of battery. Perhaps the level of accuracy is reduced only slightly, but if continuously will decrease accuracy. It could be the original battery level is still 70% only read 45% on the screen. Therefore, calibration is necessary to restore the level of accuracy of the battery level readings.

How to do it?

Actually, there has never been a standard of the vendor or manufacturer of the battery to calibrate. The most common way is as follows:

Use the device until the battery is depleted and the device turns off by itself.
Charge the battery to 100%. Not to break up the filling.
After 100%, allow up to 1 hour.
finished
There may still be other versions of how to calibrate the battery, such as repeated several times such measures even have to reset the device. But whatever it is, basically there is no specific standard battery calibration way.

What effect?

The expected effect is the measurement of the battery level becomes more accurate. For example the original battery level is still 80% yes 80% legible on the display device.
