Std EditionIИ-1 Clock 1st Prototype
Profile:This is the first design of a IИ-1 Nixie Tube clock. I learned to use the Arduino and program the Arduino through a lot of trial and error. I also learned quite a bit about shift registers.

I first discovered Nixie clocks by accident while web surfing. After reading through several Instructables, creators web pages, and how Nixies work, I decided to make one from scratch as well. I did use other authors code snippets for certain elements of the clock. In my learning, I thought I would be able to create and etch my own circuit boards. After several trials and failures I deemed this was not a viable option. I considered using OSH Park at first, but they did not have a program to draw the diagram or design the PCB. I stumbled across EasyEDA, then found that I can also prototype PCBs and have them made. It took sometime to get used to EasyEDA but once I did I found it very simple to work with. Ignore the 2 pin headers in the original schematic and the PCB that seems to do nothing. This was an idea at the time of designing to have a child board plug into the mother board. Where the child board would have the Nixie tubes to display. Please see links below for some of the projects I borrowed from as well as video of my working prototype.
