Re: [neonixie-l] Nixie doctor needed.
IN-14, very good! I connected the second tube the same way I connected the first, and the other tube works fine. I coded the second tube the same as the first, and I get all this blobbiness, and blue spots. I'll check voltages, and report back.

Hello Shane, hmm, maybe the driver does not work well enough? If the digits that are supposed to be "off" have a potential that is near ground, they might light up. Check the voltage on the faulty digits accross ground. My first guess was - without seeing the pictures - that you had tried to drive a biquinary Nixie tube as a normal one. Biquinary Nixie tubes have 0 and 1, 2 and 3, 4 and 5, you know, all even and odd numbers connected in parallel with two anodes. This way they have a standard noval socket, but require a different kind if handling. But it looks o me as though your tube was an IN-14, right?

[neonixie-l] Nixie doctor needed.
I moved up to a larger PICAXE, all is going well, except, I went to two tubes, and the new tube is...well... sickly looking. I double, and quintuple checked the connections, but as you will see in the attached photos, something is wrong. Half the digits light up fine 0-4, but 5-9, well, look terrible. they half light, and have bright blue spots at several points on the digit. Bad tube? Internal short in the tube? Thanks everyone, and sorry if I post too much, my desire for illuminated tubes is great!
