Make Your Own Retro Nixie Clock With an RTC!

In this project I will show you how to create a retro nixie clock. That means I will show you how you can control nixie tubes with a high voltage DC power supply and then I will combine 4 nixie tubes with an Arduino, a Real Time Clock (RTC) and a custom 3D printed enclosure in order to create the nixie clock. Let's get started!

The video gives you all the information you need to create your own retro nixie clock. During the next steps though I will present you some additional information.

Here you can download the Gerber files for the PCB that I created. Upload them through https://jlcpcb.com/quote#/ to order them.

Here you can find the schematic of the circuit along with reference pictures of my own assembled PCB. Feel free to use them in order to finish your own PCB.

Here you can find the code for the clock. Upload it to the Arduino with the help of an FTDI breakout board.

Also you will need to download and include the following DS1307 library: https://github.com/MajicDesigns/MD_DS1307

Here you can find the files for 3D Printing the enclosure along with reference pictures of the assembly of my clock.

You did it! You just created your own retro nixie clock!
