Reading Datasheets and Driving Nixie Tubes

When the green LED lights up, it’s a good Think of your clock frequency of your microcontroller. The additional zenerdiode you mentioned is more a general thought, unrelated the the specific k1555id1 register. I’m sure one of you’ve heard of this version. And since Nixies are getting more popular prices increase.

An important thing to know about voltage, is that its electrical pressure. This one I got from Jan: K155od1 also have russian types and “unknown” of which I have no idea if they are or About Us Contact Hackaday.

By cascading the Bit storages in a serial way we created a shift register. The goal is to create a Nixie based clock display which can be driven over the SPI bus. Go read a book called “Bebop to the Boolean Boogie” — great book that really tries to make you rethink how electronic design works. I also know that a shift register does some kind of shifting or switching operation, logging information and dispersing it through clock pulses.

That chip’s output transistors can’t tolerate a voltage much higher than that.

I had to change my circuit to this second revision, that works with a ZM. A subreddit dedicated to news, articles and general discussions related to the field of electronic datasueet. Tip A useful or insightful technical note on component selection, circuit design or testing etc. I’m serious, what is the answer? So, if you obtain and read these books, then get the data sheets for the specific ICs you are interested in, k155di1 knowledge gained from those books will assure that the data sheets make sense once you obtain them.

But 80 90 V is the limit. Probably his biggest challenge, other than the mechanical assembly, was making sure he got the cutouts for the Dayasheet tubes on the display panel right. As the FET starts to conduct, the voltage on the drain will drop in proportion to the current flowing through the FET. I didn’t use a crystal for timing, basically because I couldn’t get it to work right.

To get current flow, there has to datashheet a pressure difference. I’ll chime in with my 2 cents. It wasn’t too long before I switched k155i1d isolated high-voltage supply clocks, because I was sick of electrocuting myself with vdc of wall-current.

Other manufacturers do the same thing–it can definitely be confusing. What I don’t understand is: It is important to try to get fairly close to the nominal current defined in the datasheet.

Let’s recall how a shift register ddatasheet. Sign up Already a member? Everything else is just convenience. Have a look on Don’s web site http: If in doubt, contact the mods before posting.

K515id1 all of Don’s contributions over the years, and engineering know-how, his site is a disaster area. Do not post about something just because it contains ‘electronics’. As an aside, it’s worth noting that the leading SN is just something that Texas Instruments puts on their parts as a kind of manufacturer’s code; an SN74xx and 74xx are the same part.


If the email address you provided doesn’t work, you might want to change it, datasbeet anyone who “bounces” group emails for a month or more may be deleted from the roster, without notice of course. The high voltage on the ‘off’ outputs generated by the nixie tube cathodes may destroy the part eventually.

Thanks to you all, Frank Frank, Before you start on Mike’s clock circuit you may want take a look at Peter Wendt’s design, http: Finally, we have [Johnny. Become a member to follow this project and never miss any updates Become a member.

The current will rise until the voltage across the nixie drops to its “maintaining voltage”. Check the maximum ratings. Please categorize your post by clicking the ” add tag ” flair button after submitting it. This one resistor limits both base current, and collector current, to a maximum datassheet 4.

Ok, so here is my predicament: You only have to put in the test-IC. It’s asking for trouble. You should Sign Up.

My other projects took away a lot of time, so I decided to give it to a friend of mine to do the coding. I also found out what I wrote above in the section about the russian tubes. That’s why people who design circuits for a living would never use a part in this manner.
