Recently, a gadget called Click Quick Button has become popular. This physical button, which can be connected to a mobile phone or tablet. The button is inserted into the headphone jack and allows you to perform certain actions, such as turning on the LED flash, launching the camera, and so on. We suggest making such a gadget yourself.

So, we will need:
- glue gun;
- soldering iron;
- heat shrinkage;
- tact button;
- 3.5 mm mini-jack;
- tester;
- mobile phone.

The clock button, according to the author, can be removed from some old and unnecessary board. This is where you should start making the gadget.

After unsoldering the clock button from the board, thoroughly clean the mini-jack.

Since the tact button has four tabs, it is necessary to determine which of them are working. To do this, take the tester, switch to resistance, connect the buttons to the two legs and press it. If the tester shows a short circuit when pressed, then we have chosen the correct pair.

We bite off the remaining two legs with nippers.

Let's move on to the assembly. The mini-jack has four outputs - ground, microphone output, and left and right channels. The clock button must be soldered to ground and the microphone output.

Since the upper channels are not needed, they can be bitten off with wire cutters to make room for the button.

To prevent individual parts of the mini-jack from accidentally remaining in the mobile phone connector, add a couple of drops of superglue between them.

Solder the button to the mini-jack.

We carefully insulate the soldering area with hot glue.

We put on heat shrink and fix it.

Just recently I saw the Pressy project on Kickstarter. I decided to look at the options. It turned out that there is plenty to choose from. Klick, 360 smartkey and Mi key from Xiaomi. In general, I decided to buy it and try it in practice. I ordered a Mi key for $4 because paying $35 for the original Pressy seemed unreasonable to me, because I had doubts whether I would use it in everyday life.

I love summer best time for orders, they arrive quickly. The small parcel contained a small envelope containing a miniature button. After unpacking, I began testing it on all the devices that were at hand.

I started with the native Mi key application. The program has wide capabilities and offers to assign an action from 1 to 10 clicks. IN additional settings You can flexibly change the parameters necessary for comfortable operation of the button. In practice, the application with the Z te nubia z5s mini smartphone only responded to a single press, double, triple, etc., the second or third time.

Things were a little better with the 360 ​​smartkey app. Its capabilities are limited to assigning commands to single and double clicks. In the settings you can activate additional features. The smartphone responded quickly and accurately to all commands, but from a locked state it worked the second time.

Having tried all the applications, I settled on Klick because it worked the most correctly even when the smartphone was locked. The application allows you to combine short and long presses, but the Mi key button does not support them. I would like to draw your attention to the fact that it makes sense to try all the applications and choose the one that will work without problems with your smartphone.

After several days of using the Mi key smart button, I was satisfied. True, the only use I found for it was to launch a flashlight and camera, although sometimes it’s faster to take a picture in the traditional way by activating the camera from the lock screen. There were no accidental activations. The button can help in an unforeseen situation when you need to urgently send an SMS, make a call, or start a video recording without watching. You just need to be 100% sure that the button will work the first time. For users whose devices have diagonals larger than 5 inches, it may not be convenient to reach for the button. For those who like to listen to music from a smartphone, you will have to constantly change their places. The price of the button is small, so anyone can buy it if they want.

At the end of last summer the whole world learned about “ magical» button from the Pressy project. The creators of this idea announced the project on “ Kickstarter", planning to raise 40 thousand dollars, and eventually collected all 695 thousand. This button went from an idea to a selling model quite quickly, and can now be purchased for $27. However, many critics thought that the price was too high. Xiaomi caught this trend and came up with its own button Xiaomi Mikey(Xiaomi MiKey). It sells for less than $1 and this review will be just about her.

The essence of the work of this gadget is identical to the work of Pressy. The button itself is inserted into the 3.5 mm headset jack and controls previously specified functions and capabilities of your smartphone. To set these functions (and there are about 9 of them), you need to download a special proprietary application in Google Play or on other sites. It is possible to assign not one, but several different actions to the selected number of clicks. This review will help you look at them in more detail.

Overview of the Mi Button's capabilities

For example, Xiaomi Mi Key can take a screenshot of the screen with a single press, with a double press - turn on the flashlight or start a voice recorder, with a triple press - take pictures from the main or front camera and send them to the specified address. In addition, you can launch a window with 4 different functions of the user's choosing. There are a lot of options for action.

The mi-button counts the number of presses per day and credits certain points to the owner’s “balance.” In the parameters you can set the reaction speed, select focus during hidden shooting, activate background work and launch the toolbar in the pull-down "curtain".

Nuances

The software that powers this gadget is constantly receiving updates, and this is not the limit - there is something to improve. For example, many users complain that the Mi Key button does not respond even to a single press, let alone recognize 2, 3, 4 or more clicks. There are also cases when required program does not start immediately, but after some time - five or ten seconds, but the program is already hanging in RAM, occupying her.

It may be worth just getting used to it and calibrating the button response speed slider, however, most likely, this device will work 100% only with Xiaomi smartphone. This is understandable - there is only one manufacturer, and therefore the reaction will be predictable. In other smartphones, the operating principle will be slightly different, and therefore it is impossible to predict how the button will behave with them.

Equipment and design

Xiaomi Mi Key went on sale in six different colors. At the same time, the device itself is the same silver color, but the cases for it are multi-colored. If the user wants to connect headphones to the smartphone, then this very case can be attached to the wire, although it is very easy to lose the button in this way. But don’t worry: the price for the device is minimal. In addition, if you regularly listen to music through a wired headset, then most likely you will not need the Mi Key button.

We hope this review was useful to you. Share your experience Mi Kay in the comments!

In the wake of general enthusiasm, I bought myself some buttons for my smartphone. I found it very interesting to perform various actions in Morse code, and even without turning on the screen.

As a result, it turned out that on the one hand the buttons work, but on the other they are not very convenient to use. I'm not entirely sure that the problem is in the button, since there are enough cockroaches on the smartphone.

However, one of the purchased buttons disintegrated during the process of being removed from the phone, and I considered this sufficient reason for the post. So what follows will be an analysis of the contents of the button using a savage destructive technique.

First, in honor of Friday, a little about pricing policy. I bought the buttons, as follows from the price field, for $0.85 each. Yes, I know that it would be possible to dodge and save more, but that’s not the point now.

So here's Friday's picture: a harsh Chinese discount of 67% OFF after the traditional unrealistic price increase

I also know that this is a copy of some original button, probably Klick. I won’t talk about the original - I didn’t hold it in my hands. I’ll go over the functionality of this button.

.

Firstly, for the button to work you need an app, which you can download from the link in the QR code almost automatically, or manually - from the link. I probably won’t provide the link, because after downloading it, Avast on my smartphone complained that it might contain a virus.

Color scheme of “covers”-button holders

So I didn’t install the “native” app. And I used a rather simple and concise one, programming it for three functions by single, double and triple pressing. All of them, by the way, are recognized quite well, and the functions are executed accordingly.

The button holder, as designed by the designer, attaches it to the headphone wire

If you insert a button while the program is running, it will ask what exactly was inserted: headphones or a button, and if you open the program, the programmed actions are immediately visible.

If you insert it without launching the app, the button will turn the player on and off by default. Moreover, if a Bluetooth headset is connected, then there will be sound in it, otherwise there will be no sound.

It somehow worked in the opposite direction too. When a Bluetooth headset was connected and the button app was launched, sometimes a single press of the headset button triggered an event programmed for a single press of the smart button. For the most curious: no, double and triple clicks on the headset do not work, since at the hardware level it itself interprets double clicks as a command to redial the last dialed number.

Well, plus the settings

In general, you can hang on the button: taking a photo, voice recorder, video recording, flashlight, clearing memory, screen lock button, home screen button, calling a number, SMS and launching an application

In this case, photo shooting occurs completely unnoticed, without turning on the screen, backlight or sound. My flashlight turned on and would not turn off again - I had to restart the phone. Launching the application - like clockwork. But I confess, I didn’t check the rest.

In general, one of the advantages is that I can turn on the radio in the morning without unlocking or even opening the cover of the phone. Of the minuses: on my Mijue M880 the iKey app does not start after rebooting the phone. Moreover, if after a reboot you launch the app with the button inserted, the button does not work until you “reboot” it too.

Those. you need to remove the button, insert it, tell the program that the button is inserted, and only after that use it. Actually, it was the repeated reboot of the button caused by repeated reboots of the phone due to a faulty microSD that led to the breakdown of this very button.

Indeed, it simply shattered into pieces: the plug, the upper ring-rim and, in fact, the round “button”. Moreover, I, in fact, did not even see the latter after they separated from the main plug - this happened in the subway, and everything fell to the floor.

A round part and an inconspicuous but existing ring that fixes it, pressed into the upper part of the plug

Only the largest fragment remained in my hands - the plug. For some time he was lying in the pocket of his down jacket, and had no idea that he would become a MySKU star. But here you go.

So, a deadly number.

To begin with, this is probably how the creators of Klick imagined its rich inner world:

Those. microelectronics, board, contacts, practically nanotechnology. But we know that in China equipment is assembled using improvised means and materials. First of all, Occam's razors.

To find out exactly which extra entities were cut off with the indicated tool, I first used tweezers, and then even pliers.

This is what I have left and where it all started

Above

You can see a three-pin plug with a plastic insert pierced with a pin. At first I thought that this was a physical button that was pressed by a decorative round insert. But in reality everything turned out to be much more prosaic, but more on that below.

The lower part of the plug was the first to give way under the delicate pressure of the tweezers. It turned out that it was just a plug, not connected in any way with the two upper contacts

To the front

Then it was the turn of the middle contact. He didn’t want to give up just like that; he longed for achievement. Well, I did it to him with boring black pliers - I crushed it and tore it. However, this did not bring relief - neither to him nor to me.

But it became clear that the secret was not in the second link, but in the first. Since it is clear that the second contact goes up through the insulator

Based on the degree of miniaturization, one could assume that these are genuine nanotechnologies - after all, they had to somehow manage to cram at least some elements into the upper section.

So I had to use the last resort - those same terrifying wire cutters built into any self-respecting pliers. Surprisingly, they cut through the remains of the plug quite smoothly.

.

.

And then I realized a lot. There is no spoon, no nanotechnology. There are no buttons. The upper springy part of the “button” (while it was in place) is simply an elastic plate that closes the upper and middle contacts of the plug. Actually, this event is recorded by Android, transmitting it to the corresponding app.

The report is finished. Happy great and terrible Black Friday and good night everyone! Question and answer session - in the morning :)
