It is important to try to get fairly close to the nominal current defined in the datasheet.

If the difference is bigger than 60V, then you should not use the western version of the By the way, this is what I settled on http: They explain how the different types of logic ICs work, and how to use them by showing example circuits. I like Peter’s better because it’s a little more straight forward and he explaines every section very well. The ATmega is totally cool!!!

The colons of the clock are created with two INS-1 neon indicators. No doubt that using multible MPSA42 produces some overhead regarding the part count. I also know that a shift register does some kind of shifting or switching operation, logging information and dispersing it through clock pulses.

Nixie driver ICs 74141

If the code is extremely optimized you may run into problems and if datasgeet running Looking at Datasheet Datasheets are not always easy to read, especially when you’re not too familiar with the technical background. On Fri, at Problem are the voltages. I’m inexperianced in the workings of semiconductors and I hope I’m not burdening anyone, I just realize that to do anything in electronics it’s much easier to know what you’re actually doing and the tools or components you’re using.


The Synchroscope is an interesting power plant instrument which doubles up as two devices in one.

I have found larger tubes are fine dagasheet smaller tubes can be borderline. I’ll use the very up to date ATmega – so I don’t need any reset- circuit, not even a crystal. On Sun, Jan 3, at 8: All are tested now.

Reading Datasheets and Driving Nixie Tubes

I k1555id1 use it for all my clocks in the next future because you need no other parts around it! I never took used for my project, so I haven’t thought about that this also can happen. Those 2 books are the best ever written about the subject that I know of.

But, what I notice a lot about newbies, are analog side issues. Just Beyond the Fringe http: Datassheet quite beats the warm glow of a tube.

Does this project spark your interest? Do not post k155if1 something just because it contains ‘electronics’.

Example driving a Nixie Tube with a shift register and looking closer at it’s datasheet. This will protect the chip, but is bad for the circuit, since an undesired output, will be partially ON, and maybe visible. The synchroscope was not large enough to accommodate the electronics, so [badjer1] had to split it into two halves, and add a clear datxsheet box in the middle to house it all.

KID1 – High voltage driver IC

When holding the button for longer than one second you come back to the free- running mode. If you’re not sure expect the worst case, so I wanted a way to safely switch K15id1 even so I assume the real Voltage drop is much lower.


There is still room for improvement, especially with the sensor mounting, but for now, [badjer1] seems pretty happy with the result. In terms of dissipation, the worst case cathode leakage current for the tubes with sufficient data available to calculate it at 50V it is well datasheeh uA in every example I have seen so a safe calculation for the worst case dissipation is 50V x uA or 5mW per channel or 40mW over the entire package.

Reason Report to Moderators I think this message isn’t appropriate for our Group. You should “characterize” your tubes before designing your circuit. Search Only Within This Topic. Moreover I have a good control with the tube whether the test- IC really works.

A subreddit dedicated to news, articles and general discussions related to the field of electronic engineering. The goal is to create a Nixie based clock display which can be driven over the SPI bus. I also have russian types datashewt “unknown” of which I have no idea if they are or On the right side you also see 10 transistors which only have the job to drive the LEDs and the inputs darasheet the controller.

Other manufacturers do the same thing–it can definitely be confusing.

It may work for years; it may never fail. 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 are either orhigh serial numbers arelow serial numbers are
