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!

    I would love to make one of these, but I've got some learning to do before I can surmount it.

    If you are attempting this be aware that the US Amazon link for the Arduino is incorrect. It does not have the 3 holes at the bottom for Gnd, A6, and A7. You can actually use the board in the link if you do not attach a header and wire the PCB connection to the alternate pins on the Arduino controller as noted in his video.

    I finally bought from JLCPCB and I am not disappointed. The boards truly are high quality. I desoldered and resoldered components and all the solder pads remained intact and everything remained functional.

    Where does the 170V supply draw it's power from?

    Nice NT clock project Scott. Would the heat from the power supply be a concern being enclosed with no ventilation, from what I could see? Just wondering.

    Why does the 10k resistor need to be in series with the anode to pull the voltage to 145V? Wont this stop the voltage source from achieving the 170V initial voltage?
