Nixie Clock

I guess it’s time for my quarterly post.  It’s hard to find time to make updates anymore.  What little free time I have away from work is spent gaming or on my two newest hobbies, electronics and woodworking.

A little over a year ago I started working on a new project that required the use of a microcontroller.  Looking for something easier to use than the 68HC12 I messed with in college, I found the Arduino.  Of course I’m always out to save a buck, so rather than buy an Arduino board I decided to make my own based on various schematics available on the interwebs.

That initial project is sitting unfinished in my closet while I wait for warmer weather.  In the meantime I’ve been honing my PCB etching skills by working on a few others.  The first is a Nixie tube clock using my Arduino clone and the ArduiNix shield.


I used IN-12B tubes for the numbers and INS-1 neons for the dots.  AM and PM are designated by IN-15B and IN-15A tubes.  Two rotary switches are used to set the time, one for hours and one for minutes.  My next project, which I hope to have finished in a couple weeks, will involve tubes of a different sort.
