Clock on Soviet gas-discharge indicators under the control of the Arduino platform, version 2. Project page on the website: https://alexgyver.ru/nixieclock_v2/
I decided to make the simplest and most affordable clock project on gas discharge indicators and Arduino! Single-sided board, output components, no tin!
Boards:
- The dimensions of the board are less than 100x100mm, that is, ordering 10 such boards from the Chinese will cost $ 2, excluding delivery
- The board is one-sided, it can be made into a classic LUT without any problems!
- All components are output, even a beginner can solder
- The number of components is reduced to a minimum!
- At the moment, the project has boards for indicators IN-12 and IN-14, perhaps others will be made
- The system consists of two boards: the bottom (all control electronics) and the top (lamps and backlight LEDs)
- There are two options for the lower boards: normal (4 optocouplers, dot - LED) and with an additional optocoupler for a neon dot (5 optocouplers, dot - neon)
- The boards IN-14, IN-12, IN-12_changeling have the same lower part! Parts of the boards are interchangeable. The bottom board is different only for IN-14_neon
Hardware chips:
- The heart of the board is a full size Arduino NANO, which means easy assembly and firmware
- Power supply of the entire circuit - 5 Volts
- The high voltage generator is driven by the Arduino PWM channel
- The generator voltage is adjusted by a resistor with a twist
- Time sets RTC DS3231
- 3 buttons to set time and alarm
- Alarm buzzer
- Illumination of indicator lamps
- The project is based on Andrey Zheleznyakov's board. Thank you! Link to the project: https://goo.gl/xTVQWP
Software features:
- “Search” of numbers, preventing the indicators from oxidizing
- Alarm mode
- Smooth change in the brightness of the dot and backlight ("breathing" effect)
- Advanced settings for smooth breathing
- Setting the brightness of numbers, “points” and lamp illumination
- Two brightness modes depending on the time of day
- Different modes of switching indicators
- Smooth fade in/out
- Numeric brute force
- Enumeration of cathodes
ATTENTION! If this is your first experience with Arduino, read the manual

Boards:
- IN-14 - for indicators IN-14 with LED dot https://easyeda.com/editor#id=1d7c359f88254c9d9c7ce9de914bd4c5
- IN-14_mini_neon_dot - for IN-14 with dot - indicator (+1 optocoupler and resistor) https://easyeda.com/editor#id=be6c3cd8d42a414b8a8e5b9bdd0401bf
- IN-12 - for IN-12, the numbers are upside down (when looking at the board) https://easyeda.com/editor#id=1d7c359f88254c9d9c7ce9de914bd4c5
- IN-12_turned - for IN-12, numbers are turned correctly https://easyeda.com/editor#id=aea22745380847b5beeca679820e7565
By opening the board via the link, it can be exported to PDF, PNG or Altium (folder icon on the top left / export) for manufacturing by LUT or other methods!
When ordering boards from the Chinese, do not forget to indicate in the comment "Please make V-cut along middle thick horizontal outline" to cut the board along the middle line

Q: How to download from this fucking site?
A: On the main page of the project (where you are reading this text) there is a green button Clone or download at the top right, click it, there will be Download ZIP
Q: Some .zip file was downloaded, where is it now?
A: This is an archive. You can open it using standard Windows tools, but I think everyone has WinRAR installed on their computer, you need to right-click the archive and extract it.
