That’s why there are an additional 8 D-FlipFlops which you clock RCK after your serial data is completely clocked into the input side. Simple function generator using an AVR, built from parts I have lying around. The current will rise until the voltage across the nixie drops to its “maintaining voltage”. Some nixies have extinguishing voltages as low as V. What’s the purpose of the anode resistor? Similar projects worth following.

An important thing to know about voltage, is that its electrical pressure. About Us Contact Hackaday. By cascading the Bit storages in a serial way we created a shift register. Nothing quite beats the warm glow of a tube. Does this project spark dtasheet interest?

Search Only Within This Topic. I’m sure one of you’ve heard of this version.

Finally, we have [Johnny. The new topic will begin with this message. How do I find the range of resistance I need for a specific tube like a formula? And since Nixies are getting more popular prices increase. Check the Voltage levels for High level input 0.

Truth is, it works with datashet. The additional zenerdiode you mentioned is more a general thought, unrelated the the specific shift register. Well, most logic chips 74xx, 4xxx, Same hack time, same hack channel, bringing you the best of Hackaday. It’s so simple, that there is nearly nothing to explain.

Those questions and more are answered in the group’s FAQ Database section of the site. Fun book, to boot. Your question k1555id1 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.

Crosscheck the recommended values. You are about to report the project ” Reading Datasheets and Driving Nixie Tubes “, please tell us the reason. Please categorize your post by clicking the ” add tag ” flair button after datasbeet it. Note that tis very special one has FETs at it’s output to driver higher loads. Think of your clock frequency of your microcontroller.

74141 / K155ID1/ K1551 Nixie Driver IC

I’ll chime in with my 2 cents. The russian types have high “off” voltage approx Vso the efficiency is much better, and the “Blue Spot” problem can not occur e. Reminds me of a Geocities refuge. 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 current increases, making this an even more not straight-forward proposition.

I sat down and sketched a “super simple” driver- testing circuit to test them all. What controller are you using? Submit a new link.

You can skimp on the base resistors, since only one transistor will be ON at any one time.

There’s some good info, but datasheef nearly impossible to find. So I added a IC. View and contribute to our wiki page for beginners. Lets use a shift register. A few blue LEDs add a bit of ambient light. Typically you have a set of eight Bit-Storages since we live in a binary world. Typical of all outputs:
