Light L16 – an amazing camera with a lot of lenses

When you look at the camera Light L16, then in the head itself there is an association with the world of insects. There is a feeling that you see a spider, who looks at you with dozens of his eyes. In fact, a similar appearance camera pursues a very important goal: to save the user from cumbersome lenses and to reduce professional camera to such an extent that he can fit in your pocket.

Light L16 is a completely new type of cameras with a multi-diaphragm. While DSLR and mirrorless cameras use interchangeable lenses and one large sensor, the L16 uses many smaller lenses and smaller sensors. As components of the camera, details are used that can be found in modern smartphones. When you press the shutter release button, the image is taken at the same time by ten tiny cameras with different focal lengths, and then the images are merged together using software to create an amazingly detailed photo with a resolution of up to 52 megapixels.

Light L16 also can shoot video with a resolution of up to 4K and a fixed focal length of 35, 70 or 150 mm. Of course, the video is shot with only one lens, not several, so this function can be considered just a pleasant bonus to the basic capabilities of the camera. The camera will be available for sale in the summer of 2016, and its preliminary price is indicated at $ 1,700. Expensive? Yes, it’s expensive. But for certain there are wishing to acquire such an unusual gadget. By the way, those whopre-order on the camera within the next month, will be able to purchase it at a reduced price of $ 1,300.

American airports are equipped with tracking systems for drones

Recently, the drones have been closely integrated into our lives. They are used by photographers, cameramen, delivery services , scientists and even parents to entertain their children. But there are those people for whom drones are an additional threat to security in their difficult work. We are now talking about airport employees . The US Federal Aviation Administration (FAA) is seriously concerned about the increase in the number of drones flying dangerously close to various airports.

What would the Civil Aviation Authority do to protect airports from quadrocopters and other radio-controlled cars, people simply do not hear them. Already a law on this subject was released, and the public tried to inform, and evenspecial application for a smartphone have been published – but people do not quit and persistently continue to buzz their toys near airports.

In order to somehow protect thousands of passengers from amateur pilots, the FAA made an unusual decision. The agency teamed up with a private CACI company to test and implement at US airports the tracking technology for drones and their owners in dangerous proximity to the runway. Thus, it is planned to maximally secure the take-off and landing aircraft from collisions with radio-controlled drones.

The prototype of the new tracking system scans the radio signals that are used to control the drones, and if such signals were detected, then the system is able to find the owner of the drone in a radius of up to 8 kilometers from the airport. Initially, it is planned to install the system in several American airports for field testing. Airport names inpress release the FAA website is not specified.

Perhaps in the future, agencies from other countries will also adopt similar systems for tracking drones and their owners, as “dronomania” continues to gain momentum, and thanks to Chinese online shopping, today you can buy a radio controlled quad copter for a penny, without leaving it from home.

Kickstarter users invested in flashlight, shone from the heat of hands

Forget batteries and solar panels – the American inventor came up with a flashlight, working from touch. A small device called Lumen is equipped with a panel that converts the heat of a person’s body into an electric current to power a small LED .

Lumen length of 4 centimeters and weighing 35 grams does not have a large light power, but the brightness is not inferior to the built-in flash smartphone, often used as a flashlight. The author of the development is the engineer Ross Zhuravsky from New York.

The device is equipped with a ceramic plate – a thermoelectric element, which is designed to collect heat energy from a person’s touch. Generation of electrical energy is due to the difference in temperature.

Lumen

Reading the external temperature, Lumen “feels” when touched. The metal case of the flashlight accumulates the received heat.

On kraudfandingovoy site Kickstarter launched a campaign to raise funds for the implementation of the project, which has already managed to collect more than 40 thousand dollars from the declared 5 thousand. The campaign will last for another three weeks.

The temperature difference between the body and the environment is sufficient for the device to generate the energy needed to operate a single LED, “Zhuravsky said.

Lumen is able to produce about 15 mA and 3 volts with a relatively small temperature difference, Daily Mail writes.

Lumen

The example on Kickstarter takes into account the air temperature difference (27 ° C) and the tip of the finger (36 ° C).

When the difference is large, excess energy is accumulated in the condenser. This energy is enough to supply a 5-millimeter LED with a light output of 3000 mCd, – explained the engineer.

Lumen is from 35 dollars. For an additional $ 15, a tritium backlight is available, making it easier to find a flashlight in the dark.

ACPAD – MIDI controller that turns your guitar into an orchestra

ACPAD is the world’s first wireless MIDI controller for guitarists . This gadget is quite capable of turning a classical six-string guitar into a full-featured synthesizer with a built-in sampler, a bunch of settings and other sound buns. This device was developed by German musician Robin Sucroso, who since 2009 experimented with various prototypes and, finally, presented us with the final version of his invention.

The idea of ​​ACPAD before the ingenious is simple. You just need to stick a thin synthesizer out of the polymer substance on the frontal guitar deck, and no glue is needed, as it is fairly firmly held on the smooth surface of the guitar by itself, and at any time it can be easily peeled off without damaging the instrument. On the surface of the synthesizer are various control elements, including two sliders, 10 buttons of sound settings, two samplers with the ability to record and loop the sounds, as well as 8 round touchpads with sensitivity to the force of pressing and gold-plated contacts for more precise operation.

All functions of the synthesizer are easily configurable and programmed with the help of official software. The musician can assign to the keys the sounds of various musical instruments , thereby turning his guitar into a real orchestra. Of course, for a full gadget to work it will need to be connected to a computer or mobile device via USB or wireless. ACPAD is powered by batteries hidden in its body, which last for 4-5 hours of continuous use of the guitar.

One of the most important tasks of ACPAD developers was the minimization of delays between pressing the controller keys and playing sound. In the final version of the device, the delays were reduced to the maximum possible minimum, at which the musician does not experience any discomfort. You can see the work of the device in the video just below. The song is performed by the creator of ACPAD Robin Sucroso.

The device should go on sale in May 2016, but for now you can support the developerson kraudfanding-portal Kickstarter. ACPAD is currently available at a reduced price of 219 euros, and after it goes on sale, the price will soar to 349 euros.

A critical vulnerability has been detected in Ledger’s hardware crypto

It is generally accepted that crypto-currency hardware wallets are very reliable, and therefore are best suited for storing their savings and conducting various transactions. One of the most successful devices last year was the French hardware cryptic escort Ledger, whose sales quickly passed over a million devices. But recently, representatives of the company-developer reported that Ledger found a critical vulnerability, allowing you to substitute the final purses and steal the recipient’s own crypto currency.

To send funds or download the address of the recipient to Ledger, it must be connected to the Internet – at this stage, the attackers and get access to the device. Ledger wallets create a display address using JavaScript, and malware has the ability to change the details of the attacker’s address, after which all the money intended for the recipient will go to the scammers, and the sender will be sure that everything is in order.

So far, no one has suffered from the vulnerability in the wallet, but the developers posted a video on the site with a demonstration proving that it is real and dangerous. It is noted that the software purse stored on the PC in the folder AppData, too, can be attacked by scammers after substituting the address of the recipient.

Avoid the trick of hackers can be quite simple: the developers recommend that before making transactions, always verify the correct address of the recipient – just press the button with the monitor image. After that, the user can independently confirm the correctness of the transaction with one more click.

Even despite the occasional “holes” in the security of such devices, the use of hardware wallets is still one of the most effective and safe options for storing crypto currency, because there are absolutely no solutions at present safe from the attackers.

China prepares for sea tests of railgun

In the web there were photos of the Chinese large landing ship “Haiyanshan” of the project Type 072-III with supposedly installed in its bow “railgun”. Western media report that the testing of a new gun can begin in the near future. If this is the case, then China will be the first country to install a weapon of this class on the ship and bring it to sea for testing.

Recall that the railgun is a weapon that uses electromagnetic forces to disperse a projectile. The design of the system implies that the projectile at the first stage of the shot is part of an electrical circuit that accelerates it between two contact rails (hence the name railgun). For a shot gun needs to supply high voltage and current, which can not provide a simple connection to the electrical network. Several countries are engaged in the development of technologies for this type of weapons. China, in turn, has been working on the railgun since the early 2000s, and on the whole, research in the field of electromagnetic weapons has been conducted by the country since the 1980s.

In open access, the first information on the creation and testing of new weapons by China appeared in 2005. Then it was a question of relatively compact laboratory samples, unsuitable for scaling and use in real conditions. At the end of last year, the Marine University of Engineering Sciences of the People’s Liberation Army of China announced the development of technologies that could be used to create the railgun. Specifically, it was a method of electromagnetic propulsion of shells. There were no other details on this subject.

Pretty dimensional, not on the scale of the ship, the gun, installed in its bow, is unlike any existing artillery ship system in China. It looks like a huge tower with a barrel, behind which three sea containers are mounted on the deck. Various sources report that, probably, a charging automaton is located in the tower, while in the containers there may be an energy system, generators and a weapon control system. Also, a new element appears on the superstructure of the landing ship, which may be a radar control station for fire.

The media also notes that, as a rule, China uses Type 909 / 909A project ships to test new weapons. In total, the Navy of the People’s Liberation Army of China has four such ships, each with a displacement of 4.5 thousand tons. It is possible that the gun was so large that its power plant simply can not provide the required amount of energy railgun, so it was decided to use the ship “Haiyangshan” with a displacement of 7 thousand tons.

It should also be recalled that even earlier military prototypes of the railgun were presented by the American company General Atomics, as well as British BAE Systems. Installation BAE Systems uses as metal projectiles metal kinetic blanks weighing 16 kilograms. The muzzle energy of the gun is 32 megajoules. The muzzle energy of the prototype installation of General Atomics is 1 megajoule higher. Last summer, the US Navy Research Department, in conjunction with BAE Systems, tested a railgun mounted at the Dahlgren training ground in Virginia. As part of the tests, the gun first fired two shots in a row.

To date, the development of railguns for the US Naval Research Administration has been frozen. Engineers and military decide the fate of the project, which now seems very vague. It is possible that the project will be completely stopped. The reason for this is the complexity of the gun, its high energy consumption, the relatively low resource of the railgun barrel, and the absence at the time of the fleet of ships suitable for installation and large-scale testing of the electromagnetic installation.

Startup Citybirds has developed the “most thin and light” electric car

Recently, the developers visited the ISPO exhibition in Munich, where they presented the electric self-production of their own production called Eagle, which, according to the creators, should emphasize the elegance and ease of their offspring.

The battery capacity is enough for 15 kilometers, but the duration of the trip can be increased by inserting another battery into a special compartment on the steering column – then Eagle can drive up to thirty kilometers. You can charge the “Eagle” from the car’s cigarette lighter or from an ordinary outlet.

The scooter is capable of speeding up to 25 kilometers per hour, independently prompting the road and sharing with the owner various useful information. In addition, the scooter can report on the situation on the road and predict the weather – this is the display located on the steering wheel. In addition, it can also duplicate the screen of the smartphone and track calls, incoming messages and other information via Bluetooth.

The prototype brought to the exhibition was made of plastic, but in the series there will be a scooter made of carbon fiber. Its frame is doubled, which makes it easy to carry it on the shoulder or in a large bag, so even if the scooter batteries sit down, it will obviously not be a big burden.

The price of the scooter will be announced later, closer to the start of sales. It is planned to start production not earlier than next year.
