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. 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: 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. Please don’t ask me for chips.
and Nixie Driver Tester
Check the different truth- charts!!! Moreover I have a good control with the tube whether the test- IC really works.
It’s so simple, that there is nearly nothing to explain. I had to change my circuit to this second revision, that datqsheet with a ZM.
I got many hints from the Neonixies Gang that in some cases a defective may leak at the outputs. 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.
Truth Table for theand A Chip. Truth Table for the, A and B Chip. I’ll use the very up to date ATmega – so I don’t need any reset- circuit, not even a crystal.
My friend did the coding this time had little time When the green LED lights up, it’s a good The ZM tube is driven with 2mA current.
When the yellow LED lights up, it’s a good I sat down and sketched a “super simple” driver- testing 741411 to test them all.
You only have to put in the test-IC.
Nixie driver ICs 74141
The ATmega is totally cool!!! I also found out what I wrote above in the section about the russian tubes. I never took used for my project, so I haven’t thought about that this also can happen. I will use it for all my clocks in the next future because you need no other parts around it! Ok, lets go to the Sketch I made for my tester.
All are tested now. The button switch switches between the different datasheeh 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. The russian types are either orhigh serial numbers arelow serial numbers are Remenber that te russian types are marked like this orange! I also have russian types and “unknown” of which I have no idea if they are or dxtasheet I really find some old which don’t work or leak.
