Description

This is my final design for a NIXIE clock. I have made several and this is the best one. My gift to the universe is this in the public domain. Feel Free to make one and tell me about if you like.

the arduino code is attached, I suggest you use it as a starting point for your own code. From it you can see what pin is connected to what and how I implemented the multiplexing, you may have a more elegant method, go for it...

dont bother crediting me for any of this, all I did was reinvent something that has been invented a thousand times over. You can build it, understand it and the build something better.

But do sent a photo and/or questions if you like... I'll try to be helpful.
