After building that once, you’ll decide that a microcontroller design is less work and more flexible. I’ve read with interest your post on driving the cathodes in various ways.

Also, if you are going to use a non-regulated high-voltage supply like the one in Mike’s clock the power supply voltage will sag as datxsheet increases, making this an even more not straight-forward proposition. The Group moderators are responsible for maintaining their community and can address these issues. Check out the demo video after the break. Check out our Nixie tube project list!

The additional zenerdiode you mentioned is more a general thought, unrelated the the specific shift register. The ZM tube is driven with 2mA current. Big thanks if someone can help me out.

and Nixie Driver Tester

News An electronic engineering-related news article or announcement. But you do not want to buy an old KID1 from Ebay? Ok, so here is my predicament: As always, see you next week. Well that is a close one on this uC.


If you completely omitted the limiting resistor, your nixie would have a VERY short and eventful life. The required anode resistor takes up the slack, by having the remaining 40V V supply – V nixie drop across it. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Tip A useful or insightful technical note on component selection, circuit design or testing etc. If the selection voltage is a little low for the particular tubes used then the HV might be a better choice and still keep the parts count down.

The concepts are presented clearly, with theory, and a schematic is shown, along with a truth table of the expected results. Nixie Tubes have an anode voltage of around V. Not a nixie tube driver. All they have to due is rise to a value so that the voltage difference is less that the extinguishing voltage. How do I find the range of resistance I need for a specific tube like a formula?

IF you look at the TI datasheet for their at http: Since there is no physical connection between cathode and anode it’s something in between depending on the switching state.


Already have an account? That’s why there are datsheet additional 8 D-FlipFlops which you clock RCK after your serial data is completely clocked into the input side.

Reading Datasheets and Driving Nixie Tubes

Modular nixie display board based on the soviet Russian INA cold-cathode tubes. He also assures that you will know not only how it works, but how to build things that work reliably over the long term. When [badjer1] [Chris Muncy] got his hands on an old synchroscope which had seen better days at a nuclear power plant control room, he decided to use it as the enclosure for a long-pending plan to build a Nixie Tube project. It could fail next week or in the next hour. Thanks to you all, Frank.

On Sun, Jan 3, at 8: The Western ‘s have protection zener diodes on their outputs, that limit their rise to 60V.

No contracts, No fees, No Kidding! Your question reminds me of the PhD student who went to the exam and was asked “why is the sky Blue” – it can be answered on so many different levels.
