Found in the covers an old Soviet alarm clock, as in the photo. I decided to give the second life alarm clock and make a Nixie Clock from them (hours on gas-discharge indicators). Not leaving far from the first project, I decided to do the same under aRDUINO control Nano, but make some changes.
Finding six pieces of Indicators IN-12 and IN-17 (scales flash drive) began to breed a fee.
The first board with lamps turned out two third-party, but I have prepared a pair of boards, with jumpers and with transistor reverses TLP627 (F) instead of transistor keys on MPSA92 and MPSA42. I did not try the scheme with TLP627, you may need to correct the delay between the inclusion and shutdown of the lamps.
In this project, I removed the RGB crewing and their adjustment.
Also, I replaced the RTC module with DS1302 on DS3132, because DS1302 begins to lag behind every week.
I used the LED to display an alarm clock, connected to the 13th Pin Arduino, and in the board there is a built-in LED that works in parallel, so it can be counted or cutting it. 
The fees did, as usually led by technology, pokels in a solution of hydrogen peroxide, citric acid and cook salt, more information about this can be found on the Internet. As will be your CNC, I will make cards milling or burn the photoresist with a laser.
I decided to remove the old alarm paint and paint it into a black matte color, here's the photo of the first attempt, but it turned out not very. 
Remembering the fee, it turned out much better, immediately tested the performance of lamps and other elements on the dumping board. Important moment: The Tone () function is superimposed on the PWM signal to "3" and "11" Arduino outputs. Those., Caused, for example, for Pina "5", the Tone () function may interfere with the work of the conclusions "3" and "11". Keep this in mind when you design your devices. You can use a squeak and without a tone (), with the help of AnalogWrite, but because of the TCCR1B, the sickness does not work. Whatever she worked need:
1) From the sixth Pina to transfer to the third
2) Replace in the TCCR1B program on TCCR2B
3) Use the AnalogWrite feature instead of Tone (). 
Imagine small columns horizontally, whatever the facial fee is moved and it would be easier to insert it in the alarm clock. 
Having spent another evening to set up and debug all the elements of the clock, I finished them.
In the clock there is a alarm clock to turn it on, you need to press the button (it turned out the upstart), after pressing the LED on the front panel lights up, to turn off the alarm, you must once again click on the button. Climbing the same button, we get into the alarm setting, the LED will flash and dig out the digits to exit the mode again to press the button. The alarm clock will work every day, it will be stored before rebooting the clock. 
The work of other four buttons has not changed
1. Changing the output of the date or time, in the setup mode is a change in the discharge;
2. +1 to the adjustable number if clamping, then add will be faster;
3. -1 to the custom number if clamping, then add will be faster;
4. Input and output to the clock setting mode;
5. Turn on and off the alarm, with a debt of pressing input and output from the alarm setting mode; 
The clock is powered by the 9V-1A power supply.
All the necessary components bought on a well-known Chinese website and in radio details.
We have been accustomed to the alarm for a long time as the perpetrator of its early lift in the morning. It is on him that he is responsible for the fact that you need to get up when so I want to sleep. And not always with the alarm the relationship of understanding and consent adds. Previously, the alarm could punish, offend, but today the alarms have already been created, which themselves can go to the owner on the wheels, if he did not stand on time. And yet it does not guarantee the harmonious relationship between the alarm clock and man.
In order for the person to feel the alarm clock with his friend, the wakeoff process should be pleasant. Today's alarms can ensure that it is fully. They sparkle with gentle colorful tones, lose pleasant music or nature sounds and even flavory room. Agree, such an alarm is much nicer than our old, with a loud piercing metal ringing?
Today's alarm clocks are specially equipped with the "Antistress" function. They are created in such a way that we wake up calmly, naturally, feeling nice and comfortable.

This alarm clock is equipped with a special glowing board and an erasing marker that can be applied or messages for each other. In addition, the alarm clock has a timer, a stopwatch and a thermometer, measuring the temperature in the room. Thanks to the "Birthday" function, you can not forget about the pleasant date.

Capabilities modern computers Not limited to entertainment or educational purposes, as well as the performance of various kinds on it. Via personal computers You can successfully implement the system automation systems " smart House" But if a full control system various devices It is quite difficult and requires additional financial costs, then at least one of its function can be easily implemented independently, if you use a computer as an alarm clock.
Without installing on a computer additional programs You can start the alarm clock using the built-in in oS windows family Component "Task Scheduler". Writing step by step how to execute it in Windows 7.
- Go to the next way to start the master task wizard - "All Programs" - "Standard" - "Service" - "job scheduler".
- On the right side of the window that opened, select the "Create a simple task ...".
- In the new window that appears, assign the task name and write its short description after which click the Next button.
- In the next group of task trigger settings, select the desired startup frequency from the proposed options: daily, weekly, once, etc. After that, you also need to click the "Next" button.
- Specify the start date of the task and set the time to which the alarm must run after which click the Next button.
- In the action setting, leave the default item to "Run the program" and press the Next button again.
