DJI Inspire 2: redundancy and front camera

The Inspire 1 is used by many professionals to make efficient flights without having to deploy a large format machine. The new version was much awaited. What's new ? The main structure, made of magnesium alloy and aluminum, has been reinforced, assures DJI. The aircraft is now capable of reaching 108 km / h. Not bad to go quickly on the spot to film, then come back as fast. Autonomy is estimated at 27 minutes. It is provided by a system of two independent and heated batteries. It is possible to leave with two batteries for a complete autonomy and a redundancy in case of worry with one of the two. DJI ensures that flights are possible up to temperatures of -20 ° C!

The keyword: redundancy!

Dji-inspire-two-02-1200Inspire 2 also flies with a single battery, but shorter and without taking advantage of redundancy. Component redundancy also includes GPS, altimeter barometer, and ESC. The aircraft can fly up to an altitude of 5000 meters - let us understand, it does not mean that it can fly from the ground up to 5000 meters, DJI simply guarantees that its sensors, notably the altimeter barometer, Lifting power ensures its smooth operation up to 5000 meters. Obstacle detection and avoidance tools have been integrated into the Inspire 2: Stereo cameras are placed at the front and at the bottom, complemented by infrared sensors on top. This improves flight safety during tricky maneuvers, especially when passing in front of, on and under obstacles.

Everything for the video!

Dji-inspire-deux-05-1200New that the pilots will love: at the front of the Inspire 2 there is a non-stabilized 2-axis camera (pitch and roll, with the pitch controllable from 0 to 60 °) Control the device. The main video camera stabilized by a nacelle is therefore entirely intended for the cameraman to concentrate on the capture of the images. At the core of image processing is CineCore 2.0. It is a built-in chassis tool that handles heavy computations to facilitate the storage of video files. It adapts to the camera that is placed on the Inspire 2. The fact that it is no longer in the camera makes it lighter and easier to mount. The videos are stored in 5.2K / 30 frames per second at 4.2 Gb / s, in CinemaDNG on SSD media.

Two new stabilized cameras

Dji-xquatres-02-1200Inspire 2 can accommodate two new stabilized cameras. The first is the Zenmuse X4S offers a 1-inch, 20-megapixel sensor with a dynamic range of 11.6 stops, with a focal length of 24 mm. This entry level camera can be replaced by the Zenmuse X5S, which relies on a sensor in Micro 4/3 format. It covers a dynamic range of 12.8 stops and opens up to F / 1.7. She also films in 5.2K / 30 and 4K / 30 in format Apple ProRes2. Or in 4K / 60 frames per second in H / 264. Or in 4K / 30 in H.265. The sensor is a 20.8 megapixel.

And…

Dji-xcinqs-01-1200The rotation of the camera at 360 ° is no longer possible was already limited to 320 ° on the Inspire 1, but the Inspire 2 allows compensates by a soft rotation on the yaw, stabilized by the 3rd Axis of the camera. All settings, including focus, are made from the DJI GO application. The image of the stabilized camera is transmitted in long distance (4 km) via Lightbridge technology in 1080i / 50 and 720p / 60.

DJI Phantom 4 Pro: radio remote control, obstacles and 4K / 60

The DJI Phantom 4, best-selling in multi-shot models for shooting, is back in an improved version. What's new in the program? The Phantom 4 Pro is the first multirotor intended for the general public (despite its name "pro") capable of filming in 4K and at 60 frames per second, instead of the classical 30 or 24 images by second. If you tried to shoot a panorama by rapidly rotating the camera on itself, in 4K / 24, you know that you get a very jerky video, unpleasant for the viewer. With a frame rate of 60 frames per second, the image is streamlined for optimum results on a 4K TV. The bit rate, in terms of data, is 100 Mb / s - it will take quality memory cards to hold the shock. The sensor of the Phantom 4 Pro is a 1-inch 20-megapixel 12-stops, which should satisfy the photographers ...

Detection in all directions

Dji-phantom-four-pro-02-1200 The detection and avoidance of obstacles recently introduced in the Phantom range only concerned what was at the front of the aircraft. The Phantom 4 Pro is now equipped with 3 stereo cameras. One is in front, the other behind and the third under the camera. They allow to create a 3D model of the environment to improve the detection and propose the avoidance. Infrared sensors on both sides complete the Phantom 4's security solution. An impressive device, coupled with the FlightAutonomy module, which now allows you to fly without fear of backing up and hitting an obstacle - you will obviously have to put the system to the test , Particularly that of thin branches of trees. Only obstacles above the unit will not be detected. DJI ensures that avoidance works up to 50 km / h! The Sport mode allows it to reach 72 km / h, but without detection of obstacles.

And…

Dji-phantom-four-pro-07-1200The Phantom 4 Pro comes with a new radio control, more compact than the previous models, which operates in 2.4 or 5.8 GHz (depending on the radio environment ). It's also equipped with a GPS receiver to manage the return to the starting point and tracking, a port for a microSD memory card and an HDMI port to broadcast the video feedback signal in (It needed an accessory on previous models). It can accommodate (optional) the Crystalsky screen to display video feedback and telemetry data. Edit: It seems that the HDMI port is only available on the GL300F version, which comes with the Crystalsky screen. The GL300E version without a display (for smartphones and tablets) does not have an HDMI connector.

On the software side?

Dji-phantom-four-pro-03-1200DJI GO is enriched with a "Draw" function: it draws the itinerary of the Phantom 4 Pro to the screen, and it follows it ... "Narrow Sensing" allows to fly in a Environment, between obstacles, without risking the fatal touch. There are always "ActiveTrack" functions for tracking people and objects, "Profile" and "Spotlight" which have been enriched with the detection of obstacles in all directions. "TapFly", which controls the Phantom 4 by touching a target point on the screen, gains modes to steal camera towards you, so camera facing back, and with a free orientation to point the camera at will during the flight. Finally, the "AR Route" function displays the flight path in the form of a dotted line on the screen to better manage the positioning of the camera. The price of the Phantom 4 Pro is 1699 €.

JJRC H20W in Spanish: A mini drone with FPV WIFI camera

The drones with FPV camera for WiFi are not exactly to my liking as a rule. When the real time image of the camera of a drone reaches you via WiFi, it usually gives many problems in the lower price ranges of this hobby (interference, exaggerated delay in the image, very blurry ...) but with this JJRC H20W I have to Recognize that I have been impressed with what it offers. Let's go with the review.

We can not be confused: the JJRC H20W is not a normal JJRC H20 with FPV camera. They are drones that aesthetically have made them very similar but that in the rest they do not resemble at all: in size, flight style, control .. Nothing. We are facing a drone much closer to the range of mini drones (a bigger palm of a hand) whose references are the Hubsan X4 h107, Syma X11, JJRC H6C ... things like that.

On the other hand, and leaving the FPV and recording the camera for the end, we have to emphasize greatly its great resistance to the wind. We are facing a drone that knows how to fight wind gusts of 20km / h, which for a drone of this type has a lot of merit. It is a pleasure to see how JJRC strives every day to make drones that can with this type of unforeseen, since it is of the most important in this range to improve these points.

As for normal flight, we are facing a really stable drone if you like but also with a very fast one. We can get to complete circuits fairly fast compared to the price and strength of this drone, which leaves hallucinated many times. It may be that its higher speed mode is very unstable and especially fast in the beginning, but once mastered ... will be one of the greatest pleasures in flying this drone.

Regarding the range, make it clear that it is not a drone to move it beyond 20 or 30 meters, since we can not control it with the view and it starts to give dots of sporadic signal loss. It is not a very bad thing, but I would not take it beyond those distances, which is when the eye starts not to distinguish well the nose of the drone's ass). About its autonomy, we are before the 6 minutes or 7 long, depending on how you fly and such, but how we can exchange their batteries ... I think it is something very interesting and positive for this drone.

On your FPV, say that we are not before one that goes by the frequency of 5.8 gHz (which is the most normal and recommended to watch the video in real time) but if it perfectly achieves its goal: to be able to control the drone from the screen . We may sometimes find ourselves in greater delays, it may, but that is not the norm, seeing in real time a great caldiad of video that will allow us to recognize the terrain perfectly.

Another theme is how you record the drone's camera to see it in your house. A very bad video quality that will hardly serve to make small assemblies or things like that. Low definition, very moved, deformations and too saturated colors ... Come on, let alone the format, which is not exactly too friendly.

In short, this is a very interesting drone and if you are convinced by the concepts I mentioned in the article you should go head over it, since the price, to this day, is not too bad.

Additionally, if you need to purchase some rc drone parts, you can search via Banggood website, which is one of the wholesale platform to provide affordable prices, such as camera keychain, f645 helicopter camera, etc.

ELECTROACOUSTIC GUITAR: INSTRUMENT UNIT, BASIC ERRORS AND BUYING

Electroacoustic guitar is not different from its non-electrical relatives except a loud pop sound. Conventional acoustic guitars and classical, and Western-style sound is too quiet, even to speak with them in a small cafe. The first time this problem was solved by inserting into the cavity of a small microphone guitar. The sound quality was not so hot, but the musician heard the whole room. As technology sound "clean", and on the music scene, a new high-grade instrument - guitar electroacoustic.

Classification 

The guitars of this subspecies is traditionally divided into two types: "classic" (nylon strings, soft and muffled sound) and "Western" (strings of iron, sound sharp and ringing). Qualitative differences in them no - it is entirely a matter of taste. On the classical guitar playing classical music and flamenco, and the "western" (otherwise it is called "Dreadnought") - rock, country, blues, etc., in other words, everything.

Also it is necessary to dispel one very well-known fallacy. Some players confuse poluakustiku and electro. Common among these are almost no tools. They have a different sound, different roles in different composition and playing technique. Listen fire hit Seven Nation Army. This song is completely recorded on acoustic-electric guitars. Is it similar to the melodic trills conventional acoustic?

Device 

Before turning to the topic of choice and purchase of a guitar, you should start to deal with its device. Guitar electro-acoustic model of your device is very similar to an electric guitar. So, the musician touches chord ... and here begins a long while and instant way of musical notes from the instrument to the ears of the listeners. Piezoelectric transducer immediately catches the string vibrations and converts them into an electrical signal. It can be made from various materials and be in different places, but the role it always the same. Then, the preamplifier (aka preamp) grabs a damped piezo signal, amplifies it and transmits to the outside world (eg, combo amp). Located preamp, usually directly in the shell. Equalization is located in one nest with a preamplifier. Its purpose is to gauge the tone sound of the guitar. Number of custom levers can vary from 1 to 7 (very much affects the value of the instrument). Below is a picture with the "preamp EQ."

Recommendations for choosing 

Outset that beginners buy electroacoustics contraindicated! Instead of quiet systematic study of game technology for the beginner guitar must first be busy setting up the instrument and its frequency amplifier. And the price of such a system of tools is 20-30% higher than that of a normal guitar. The main purpose of electro-acoustic guitar - concerts and recording. This is very important, because to record the normal "mechanical" tool is much more complicated. Concert with it too difficult to give. Because of this and should start when choosing an instrument. And yes, it is worth remembering that when buying electroacoustic guitar percent 20% of the budget will have to spend on its "horn" - combo amp.

First level 

The market presents a variety of electro-acoustic guitar, the prices of which start somewhere around $ 150. It is better to pay $ 20 more and get a complete tool for the novice. He can and will come forward and register. Equalizer on this guitar will have only two regulator - the volume and the overall tone. 

Average level 

The musicians of the mid-level, of course, will not be enough. Electro-acoustic guitar Yamaha (even the cheapest) as a whole would meet their needs. Also pay attention to brands such as Cort and Fender. Prices for such instruments start at $ 350. On this guitar can be much thinner adjust timbre, and reliability they are much higher than cheaper counterparts. 

Advanced level 

For guitarists who catch tiniest deviations from the norms of sound, or for those who choose a guitar-companion for life, there is a premium brand of the Crafter, electro-acoustic guitar which otshumeli at thousands of concerts. They play psychedelic and Status Quo, and dark and mad grotesque Alice Cooper. In addition the firm Crafter has also Takamine, and Taylor. We do not insist on the fact that the choice is worth something because of these brands. Just before buying, carefully check the credibility of the brand, because the electric acoustic guitar, reviews of which is infinitely angry, hardly will live long. Do not forget that comments of ordinary people is more valuable than any advertising. Prices of premium guitars start somewhere on eight hundred dollars and tend to infinity. But the optimum range - is at 800-1400. E.

Additionally, if you need to purchase some entry-level musical instruments or parts, you can search via Banggood, which is one of the wholesale platform to provide affordable prices, such as mini finger drums, flexible roll up piano, etc.

Mobius Mini, the test

This is a mini camera that is similar to keychains, that is to say size keychain. The first such was the 808 # 16 (tested in December 2012), a model that is still used despite its definition of 1280 x 720 pixels at 30 frames per second. Why ? Because all the models that have succeeded are heavier and bulkier. Here now the Mini Mobius, who finds a keychain size, while offering more advanced features, including the ability to shoot Full HD at 60 frames per second.

dsc_0011-1200Commençons by the dimensions and weight, since these are the main features for a mini camera. It measures 5.4 cm long (counting his goal that exceeds 5 mm), 2.9 wide and 1.4 thick, and weighs 27.4 grams. including the battery? Yes, indeed there is no choice, the battery is integrated, non-removable. On top, we see only a diode. Below, there are 4 no metal screws that both fixing base and heat conductor. On the right spine are the power button and the hatch to accommodate a microSD memory card.

dsc_0020-1200Sur the left edge, there is a further diode, a button with a camera icon, another noted "M". At the rear, there is the miniUSB socket as the 808 # 16, the Mobius Mobius and 2. There are also two screws to open the box, a small hole behind which is hidden a diode, and another small hole for the reset of the camera. The lens of Mobius Mini A (FOV of 110 °) or B (FOV of 135 °). How to recognize them for sure, if for example you buy a used camera? The center of the lens A is red, the center of the lens B is green. The camera I tested is a version of B.

The promise of this Mobius Mini?

dsc_0024-1200Ce are images similar to the Mobius 2 of 2 RunCam or Legend 1 with a mode 1920 x 1080 pixels at 60 frames per second. A mode that promises Full HD videos without stuttering, even by performing panning or at high speed. She also filmed in 1920 x 1440 pixels at 30 frames per second in 1280 x 720 pixels and 120 fps and 848 x 480 pixels at 240 frames per second. The formats with a number of images per second over 60 are intended to produce beautiful slowed. Like the previous Mobius, the Mini lacks functions without wifi and Bluetooth, but it can be used to return a video in real time via its miniUSB connector.

So ? Promises kept?

All shooting modes are at the rendezvous. The pictures are rather nice, with a steep dive, maybe a little too much (much like the RunCam 2), and color quite respectful of reality. The camera offers many settings to adapt the camera to the environment, to center the focus, etc. image1Pour access these settings, you need to download the small software (here), compatible with all versions of Mobius, and the 808 # 16, and is available in French. But it only works with Windows. There is also an alternative version for Android, if you have an OTG cable. But nothing for Mac OS X or iOS, or Linux. The other solution to make adjustments to fully pass computer or smartphone. The camera comes with a USB cable that ends with servos made for video, power and audio, Boscam type (as opposed to ImmersionRC format). Simply connect the video jack to a video transmitter to get the image in real time on a screen or in FPV glasses. 3 camera buttons to navigate menus. But all functions are not available: for example it is impossible to access the photo settings: Definition, timelapse, etc.

Additionally, if you need to purchase some rc drones gadgets, you can search via Banggood, which is one of the wholesale platform to provide affordable prices, such as radiolink receiver, 12a brushless esc, etc.
