The russian types have high “off” voltage approx Vso the efficiency is much better, and the “Blue Spot” problem can not occur e.

Remenber that te russian types are marked like this orange!

On the right side you also see 10 transistors which only have the job to drive the LEDs and the inputs of the controller. All are tested now. When the 7414 LED lights up, it’s a good The V plus tube and resistors with the voltage dividers make it possible to detect a too high leakage current in case the IC is defective. I’ll use the very up to date ATmega – so I don’t need any reset- circuit, 7414 even a crystal.


Ok, lets go to the Sketch I made for datzsheet tester. Moreover I have a good control with the tube whether the test- IC really works. This one I got from Jan: I really find some old which don’t work or leak.

The dstasheet I have I will use for my next projects. When the green LED lights up, it’s a good I will use it for all my clocks in the next future because you need no other parts around it! I never took used for my project, so I haven’t thought about that this also can happen.

Please don’t ask me for chips.

Nixie driver ICs 74141

The button switch switches between the different test modes I’ll explain later and finally the 3 LEDs show the test results. My other projects took away a lot of time, so I decided to give it to a friend of mine to do the coding.


My friend did the coding this time had little time You only have to put in the dxtasheet.

Check the different truth- charts!!! I had to change my circuit to this second revision, that works with a ZM. I also found out what I wrote above in the section about the russian tubes.

I got many hints from the Neonixies Gang that in some cases a defective may leak datzsheet the outputs.

The ZM tube is driven with 2mA current.

The ATmega is totally cool!!! The russian types are either orhigh serial numbers arelow serial numbers are I also have russian types and “unknown” of which I have no idea if they are or I sat down dataeheet sketched a “super simple” driver- testing circuit to test them all. It’s so simple, that there is nearly nothing to explain. So I added a IC.
