Re: [neonixie-l] Re: In18 displaying cathode poisoning after 1000hrs or less.

Hi folks, I have had some time to troubleshoot my clock. I found that when running in night mode the tubes are supplied with around 1 mA, and when in day mode are supplied 5 mA. These readings are taken between the annode resistor (10k) and annode. My understanding is the tubes should

[neonixie-l] Datasheet, pinout, or hint for IV-29 single-dot VFD?

Several years ago I purchased two IN-28 and two IV-29 from a gentleman in Ukraine. The IN-28s I used in a Nixie clock project, but the IV-29s are still sitting in my tube collection. If I had any data at the time, I've since lost it, and careful googling doesn't offer any hints. The IV-29

Before I proceed, I would like to paraphrase the original article I read on DecadeCounter (here presented to you courtesy of the WayBack machine, because I can't find the original any more):
