Vibration alarm on the guard of sleep
In the winter, when there was an extreme lack of sun, I used a light-illuminator for the comfortable awakening , which I already wrote about. This alarm clock first increases its brightness, simulating the sunrise, and then begins to sing, ring and wake its owner with all possible sounds. But what to do if a small child sleeps in a room or does the schedule for lifting you and your companion differ? A very selective alarm clock is required. It seems that I have found a solution to this problem for myself - this is a vibration alarm.

Inspection
According to tradition, we begin with a complete set and an external inspection. The device is as simple as effective. In fact, these are big wrist watches (and not only) with a beeper and a vibration motor. The kit includes the watch itself, a rubber cuff and an AAA battery.

The rubber bracelet is wide enough for a comfortable attachment to any hand. It can also be attached to the forearm. Adjustment of the size is carried out by means of a flypaper in very wide limits.

On the same rubber strap there is a loop for attaching the vibration alarm. What is important, the alarm clock has a clip, which can be hooked on at least a t-shirt, at least on the edge of the trousers. This will allow tactile to feel the vibration, for example, during working hours when the surround sound is too loud to hear the beeper. If you use a rubber cuff, it is desirable to make sure that the watch is as close as possible to the hand.
Curiosity always leads to the opening of any technology, so take a screwdriver, unscrew a couple of screws and remove the case. As can be seen in the picture, the speaker and the vibration motor are placed on the back wall to fit snugly to the arm.

Setup and operation
The alarm has 4 buttons and one switch. Three buttons are responsible for setting the modes, the fourth - for the three-second switching on the backlight. It should be noted that the backlight is dim, but it is a big plus. In the daytime, the numbers are already visible well, but at night, if you want to see the time, the bright light will dazzle. So dim backlight not only saves the battery, but also does not make the night squint.
This vibro alarm has a stopwatch mode. And let this function is not needed especially often, but it will not be superfluous either. The calendar is configured up to the day of the week, that is, you can always see the date, month, day of the week and the current time.
Present in this watch is a great function of a pending alarm. That is, if on waking to press any button except Reset, the alarm will work again after 5 minutes. Sometimes this function saves, especially those whose revival is similar to the illustration below.

There is also an hourly alarm function. That is, every hour there will be a short beeper sound or vibration. It is necessary only in order to be able to celebrate the onset of each new hour. Disabling this feature is completely illogical and not immediately understandable, if you do not look into the instructions enclosed in the box. I will carry out the operation of turning off and turning on the hourly notification with a separate quote so that the new owners will not have to re-read the entire instruction in search of the cherished lines.
Finally, it is worthwhile to demonstrate how the device works in the mode of vibration and sound.
Final impressions
I used to wake up by the sound of an alarm clock or by the internal clock. Quite often, I open my eyes a few minutes before the alarm goes off. I must say that I even woke up at night and watched the time on the dial, using the backlight - it really isn’t blind. As for the feeling of vibration, it is felt. Vibration is noticeable, but the sound of the vibration motor is also audible - this is the inevitable price for the plastic case. It is not so loud, but if the hand with this watch lies on the pillow next to the head, then it is quite possible to wake up from this sound. When you want to replace the vibration with sound, you should check if its volume is enough to wake up, because I saw people who, in their normal state, could not wake up from a phone call.
But the most important thing is that such an alarm clock will not wake up the child sleeping in the same room, so the further sleep of the household will be saved, and you will not sleep.

To turn off the alarm every hour, press "Time set" and "Mode" at the same time again - the days of the week on the display will disappear
