I also found out what I wrote above in the section about the russian tubes. You only have to put in the test-IC.

The button switch switches between the different test modes I’ll explain later and finally the 3 LEDs show the test results. I’ll use the very up to date ATmega – so I don’t need any reset- circuit, not datqsheet a crystal. The ones I have I will use for my next projects. When holding the button for longer than one second you come back to the free- running mode.


On the right side you also see 10 transistors which only have the job to drive the LEDs and the inputs of the controller. So I added a IC. It’s so simple, that there is nearly nothing to explain. I got many hints from the Neonixies Gang that in some cases a defective may leak at the outputs. All are tested now. The V ratasheet tube and resistors with the voltage dividers make it possible to detect a too high leakage current in case the IC is defective.

My friend did the coding this time had little time Ok, lets go to the Sketch I made for my tester.

The russian types have high “off” voltage approx Vso the efficiency is much better, and the “Blue Spot” problem can not occur e. This one I got from Jan: Moreover I have a good control with the tube whether dqtasheet test- IC really works.

My other projects took away a lot of time, so I decided to give it to a friend of mine to do the coding.

Check the different truth- charts!!! The russian types are either orhigh serial numbers arelow serial numbers are I had to change my circuit to this second revision, that works with a ZM. Remenber that te russian types are marked like this orange!


The ATmega is totally cool!!! I sat down and sketched a “super simple” driver- testing circuit to test them all.

Truth Table for the, A and B Chip. I never took used for my project, so I haven’t thought about that this also can happen. I really find some old which don’t work or leak. When the green LED lights up, it’s a good Truth Table for theand A Chip. When the yellow LED lights up, it’s a good The ZM tube is driven with 2mA current.

I also have russian types and “unknown” of which I have no idea if they are or I will use it for all my clocks in the next future because you need no other parts around it!

Please don’t ask me for chips.
