Hi everyone, I have been working on this for awhile now and thought I knew how to fix my problem but ended up creating another. I have made this nixie tube clock with the base from scratch and the board from GRA & AFCH. The initial problem that I ran into was since the wire I was using was 12 inches long there was not enough current to push up through to light the nixie tubes and only partial pieces of the numbers were lit. So my thought was that each tube has it's own resistors and after emailing GRA & AFCH and confirmed that replacing resistor 1-6 it would increase the current going to the tubes. So I took the trial and error approach and slowly worked my way down from the 23k (3k intervals) chip resistor that it came with to the 1k resistor that I am currently at. Probably trial and error was not the best approach. So currently I have hit the point where the number is fully lit but now it has all numbers within the tube lit. So now I am wondering what my next step should be or where I went wrong because I have hit a wall. Any suggestions or direction to go in would be greatly appreciated. Thanks.
