The iblazr external LED flash for smartphones got a start in life. External flash for smartphone - to help youtubers Led flash - LED flash for phone

On occasion, I bought such a device. Of course, there are flaws in it, but you can also achieve certain benefits.
Under<сut>disassembly, detailed illustration of the capabilities and video version of the review. I beg!
I traditionally do not cover the issues of ordering and delivery. First of all, because they are purely individual and, depending on the localization of the buyer, the terms can differ significantly. Yes, and shaking wrapping candy wrappers for all to see, in my opinion, is somehow pointless. It will be more important to indicate that the parcel moved with an international track, and the packaging was sufficient to preserve the contents.

So, the flash comes in a factory cardboard box (6x10x1.5 cm). The front of which is occupied with the image of goods in all possible body colors and replete with pictograms illustrating consumer properties.

From the back, we already see some kind of clarifications on this matter, but I hereby warn you to peer into the photo and try to read something on it. First of all, because all the characteristics are described in detail on. And secondly, because the ability of this device is in fact one: shine, consuming the charge of the built-in battery... He copes with her; the rest is details.

The set comes with only a standard micro-USB cable, which is not surprising given the box's dimensions.

It is simple and short (about 22 cm) and for some reason white, despite the fact that I bought a flash in a black body.

The flash itself is pretty compact too. And it is a flattened parallelepiped with a square base, the corners and edges of which are smoothly rounded. And the front side is almost completely occupied by a panel of LEDs arranged in a 4x4 matrix.

On the bottom edge there are (from left to right) a micro-USB connector for recharging the built-in battery, a hole for attaching a lanyard or lanyard (not included) and a mini-jack plug for switching and attaching to a smartphone.

And the right and left sides bear a switch and a three-position switch for the intensity of the glow, respectively.
For those who are interested in looking at the printed circuit board and electronic components - the photo under the spoiler.

Disassembly

The case on plastic dowels can be pry off from the side of any of the switches, even with a fingernail. The parts of the case are easily separated, there is not even glue. Regarding the installation of radio elements, negligence immediately catches the eye: the edge of the board with notches and not the flux is not washed off in the area of the contact pads of the plug.

Behind this disgrace, we see a lithium battery with a charge controller, toggle switches and a few more smd-cells.

Now, on to the matter, the use of this flash is supposed in conjunction with the iBlazr application, which can be downloaded to your mobile device by scanning the QR code from the package (here is the link encrypted in the code -). It is supposed to support the most popular operating systems: Android, IOS7 and Windowsphone, in fact, I never managed to comfortably launch this application.
However, the presence of mechanical controls allows the flash to be used in manual mode. That's what we'll do.

Here it is St. Petersburg's reckoning for the white nights - pitch darkness already at half past seven in the evening. Let's take this photo as a reference. For a starting point.

I took a photo session of the window from a distance of 2 meters. And already at the minimum brightness, you can see the outlines of objects.

Medium brightness allows you to see contours and tints.

And the maximum is clear shapes and even colors.
Therefore, I think it would be appropriate to voice an intermediate conclusion: despite the incorrect operation of the software (in particular, the android application), the flash is efficient, and with a certain skill, even useful.
But let's not forget that its direct purpose is a selfie, and then I will be the main person involved in the photo shoot.

Hmm ... even at a minimum, I am recognizable and distinguishable when photographing at arm's length.

As the brightness increases, the quality of the photo increases proportionally. But equally, a negative factor is aggravated - glare in the lenses of glasses, for example.

Although, of course, it can be avoided by changing the angle of tilt / rotation of the head or even removing them altogether. But this is more a problem of bespectacled people, not a flash.

Well, in the end, a short video, as promised.

The review turned out to be quite long, so it will not be superfluous to recall the main points of the device reviewed today.

Does not consume smartphone battery power.
+ Lightweight, small, mobile. Weight-dimensional characteristics and the presence of a standard loop on the body allow you to carry it on a bunch of keys.
± Hence the questionable point: I worked at full brightness for about 37 minutes, but it does not charge much longer either.
+ Ability to adjust the brightness or even turn off completely
+ Universal connector for charging
+ Has a signaling LED indicating charging, which goes out when finished.
- Crooked software

Now I say goodbye. All good!

Hello friends! It just so happened historically that I can not always take something with a camera in the daytime. Sometimes you have to take pictures in the dark, with a smartphone. In my case, this is Nokia Lumia 520. For those who do not know - it is equipped with a 5MP camera without flash. And sometimes it is necessary to "take on a pencil" the daily routine of this or that institution. In the dark, it is far from always possible to properly photograph the operating mode of a particular institution - there is insufficient lighting and, as a result, the camera cannot focus normally. But I solved the problem with such an external flash.

This kit includes, in fact, the device itself and a USB charging cable. Yes, I have not sealed myself - for charging.

Firstly, this is not a flash, but a backlight - this will be more correct, since it is turned on manually.

The question is quite logical - why then 3.5mm jack on it? It's very simple - it is through him that the flash is attached to the smartphone. But at the same time, there is no electrical connection between the smartphone and the flash. That is, we turn on the backlight, take a frame (or video), and turn it off. And that's all.

Of the interesting things, we can also highlight the fact that the device has 3 backlight modes.

L is an abbreviation for Low, that is, this is the minimum mode. In this mode, the backlight will not shine very brightly, but for a long time.
M is an abbreviation for Medium, that is, medium and medium.
H is short for High. This is the brightest and most voracious highlighting mode.

By LEDs. I do not know if this is good or bad, but here LEDs are used and cold and warm glow.

The stupidest question that I was asked about this flash - "and if it is not connected anywhere, will it work?" With a charged battery, it will be.

Now let's move on to testing.

I think the first thing it would be logical to show it in action, but since I was brought up on the principle of "listen to what they say and do the opposite" (like most), I decided to start by testing the battery capacity.

What do we need for the test?

1) the flash itself with the battery already discharged to zero.
2) USB charger. It works for me from the outlet.

Any Auerbank, computer or laptop can be used as such a charger.

3) USB tester. In my case, it is.

In short - this USB tester combines a charging stopwatch, voltmeter, ammeter, and capacity counter.

4) Cable USB 'papa - microUSB "mother. That is, the one that comes with the kit.

From all this stuff, we will put together just such a schematic.

Then we plug the charger into an outlet and after the end of the charge we calculate the capacity of the built-in battery.

Before carrying out the test, it is better to either rewrite the initial indicators of the tester somewhere, or reset it to zero. I reset to zero.

Now we connect the charger to the outlet. With the help of a USB tester, you can also observe what kind of current is charging. In our case, these are "symbolic" 70mA.

Notice the red indicator on the flash came on.

This indicates that charging has not yet been completed. As soon as it goes out, charging is complete.

After 35 minutes, the tester shows that the current has dropped from 70 to 20 mA, which means that charging is nearing the end. At the same time, 35 mAh “hit” on the counter.

Interestingly, after a minute the stopwatch was stopped, and the current dropped to zero. The final reading is 36 mAh.

I agree, this is not much, but I think it will be enough to illuminate the photographing area.

This test does not mean that the flash meets (or does not meet) the declared characteristics, since they are not indicated anywhere at all. That is, this is just an informative test - so that they know.

The second test is just the same demonstration of flash in action. The photos will be taken on the Nokia Lumia 520 smartphone with three flash options, as well as without it. The smartphone will be mounted on a tripod and the photos will be taken with the main room turned off. And since the room is a basement with three small windows (and they are half obstructed), then everything will be very bad with the initial lighting.

I will take pictures of this wonderful powerbank from Duracell PPS2. To make the difference more clearly visible, I set ISO = 100, fortunately, the camera settings on the Lumia 520 allow this to be done.

So, let's see.

The difference is more than obvious. Of course, with such lighting, it is much more reasonable to use the minimum mode - it is enough to properly illuminate what you need. And in brighter natural light, it's more efficient to use brighter modes.

The only drawback that I found with this flash is glass. LEDs hit the eyes hard enough, literally cut. Therefore, it would be better to make the glass frosted. That is why this flash, I'm afraid, is not suitable for selfies, photographing animals, people, and so on. But it is suitable for those who constantly shoot video reviews on a smartphone. This is especially true for those who actively buy something on Aliexpress, BangGood, eBeye, and other garbage cans.

Hello dear friends!

In Russia, I somehow did not meet them on sale ... only on the Internet. The spread of prices for them hoo. The average price, which I came across about 1000 rubles, but there is also more expensive. I decided to look for this little thing on Ali and, naturally, found these rings there at a much more attractive price.

So, the deal is done. Package sent. We wait. By the way, we didn't have to wait long. Only 13 days. And now my purchase is in my hands.

The packaging is a cardboard box with a transparent window on the front. Well, let's not go into detailed descriptions - you can see everything in the photo))

Opening the cardboard box, I found inside the actual ring on a transparent molded stand. The size of the ring is 8.5 cm in diameter. It will definitely fit my phone. For reference: I have a Samsung galaxy J3.

The flash ring is a round clothespin with LEDs on the front and a battery compartment on the back.

To tell the truth, I was already eager to try this little thing in action. Batteries were inserted into the ring, of which 2 pieces of AAA format (little fingers) were needed, and then a setup was waiting for me. The battery cover just didn't close! I don’t even know what it’s connected with ... There is no marriage! Without batteries, the compartment closes normally, without any difficulty. I tried to insert other little finger batteries - the same story. If you include the theory that all things around are alive ... maybe he is embarrassed to close in front of strangers?)) But seriously, maybe the Chinese have little finger batteries in a volume slimmer than ours? Or how, then, to explain the current situation? In any case, I can't help but remove one star for this item.

It was not possible to close the battery compartment, so I sealed it with colored tape and tell everyone that it was intended.

On the ring, in addition to the battery compartment, there is a button that turns on the light. She's only one. If you press it 1 time, then it will simply turn on, and if you press it 2 times, the light will become brighter. And if 3 times ??? Right!!! Pressing the button 3 times will turn on the brightest mode. The fourth press will turn off the ring.

The ring turned out to be quite convenient in use. It can be fixed on the phone simply and firmly. Do you know why? Because on the inner surface of the ring, where it touches the phone, there are silicone inserts that not only firmly fix the ring on the device, but also protect its surface from possible scratches (in fact, from itself). This item was appreciated by me. Thanks to

Want to see what effect the ring has in use? I know, of course you do! I tried to take some photos. Below I am posting a collage. For this photo test, I specially found the most unlit corner in my apartment. Look, the darkest option is no flash at all. Slightly lighter is the weakest ring mode. Even brighter - medium lighting. The lightest in this series is the third and brightest lighting mode.

I also did a photo test using a low light source in the frame. Take a look. The effect is present and quite obvious.

After all of the above, I will summarize, the flash ring is a fun and practical thing. I am sure that it will not gather dust on the shelf and will not get lost. My daughter is already looking at this ring with interest and has already managed to try it on on her phone. Most likely it will be in use for two. I am sure that this kind of flash can be a good help for manicurists and various needlewomen in shooting their masterpieces. In addition, it will not leave indifferent selfie lovers and various party-goers who like to shoot in dimly lit places.

And even with selfie shots, small circles are reflected in the eyes)) Funny effect))

My opinion in the flash ring is quite decent and despite the confusion with the battery compartment, I recommend this product! And for this money, this is generally a godsend.

I wish you good shopping and great mood!

As you know, a phone flash can be used as a flashlight. But with prolonged use, it can burn out and fail, and it also consumes a large amount of electricity, which is why the phone's battery is quickly discharged.
The advantages of my flashlight option:

Compact size.
Bright light (slightly inferior to phone flash).
Low power consumption.
Ease of manufacture.

For manufacturing we need:
1. LED (diameter 5 mm, voltage 3 volts, white color).
2. Resistor 100. Ohm.
3. Micro USB plug with housing.
From tools: soldering iron and wire cutters.

Manufacturing process:

1.Approximately determine the length of the legs of the resistor and LED.
2.Ludy all contacts.
3. We need to close pins 1 and 2 of the Micro USB with a jumper (as shown in the picture).
4. We solder the LED to the resistor (in this case, it does not matter to which contact, without observing the polarity).
5.Pin 3 is (+) and pin 1 (-) (as shown in the picture), solder the plus of the LED to the plus of the plug and minus to the minus.
6. It remains to install the micro USB into the case and close it.
Thank you for the attention!
