Dqtasheet 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. So I added a IC.

Nixie driver ICs 74141

It’s so simple, that there is nearly nothing to explain. Remenber that te russian types are marked like this orange! The ones I have I will use for my next projects. The ATmega is totally cool!!!

I had to change my circuit to this second revision, that works with a ZM. All are tested now. Moreover I have a good control with the tube whether the test- IC really works.

When holding the button for longer than one second you come back to the free- running mode. Check the different truth- charts!!! I got many hints from the Neonixies Gang that in some cases a defective may leak at the outputs.

When the green LED lights up, it’s a good Ok, lets go to the Sketch I made for my tester. Truth Table for theand A Chip. Truth Table for the, A and B Chip. I sat down and sketched a “super simple” driver- testing circuit to test them all.

The russian types have high “off” voltage approx Vso the efficiency is much better, and the “Blue Spot” problem can not occur e. 744141 really find some old which don’t work or leak.

This one I got from Jan: My friend did the coding this time had little time Please don’t ask me for chips. The button switch switches between the different test modes I’ll explain later and finally the 3 LEDs show the test results.

When the yellow LED lights up, it’s a good On the right side you also see 10 transistors which only have the job to drive the LEDs and the inputs of the controller. My other projects took away a lot of time, datasheeet I datasheey to give it to a friend of mine to do the coding. I will use it for all my clocks in the next future because you need no other parts around it!

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 datashedt I also found out what I wrote above in the section about the russian tubes.

You only have to put in the test-IC. Vatasheet never took used for my project, so I haven’t thought about that this also can happen. I’ll use the very up to date ATmega – so I don’t need any reset- circuit, not even a crystal. The ZM tube is driven with 2mA current.
