Once ignited, current starts to flow. By cascading the Bit storages in a serial way we created a shift register. So, if you obtain and read these books, then get the data sheets for the specific ICs you are interested in, the knowledge gained from those books will assure that the data sheets make sense once you obtain them. Modular nixie display board based on the soviet Russian INA cold-cathode tubes. The data sheet states and shows in the output schematic that the output is clamped with a 50V Zener between the drain and gate. Check the maximum ratings.

Kizahn I got many hints from the Neonixies Gang that in some cases a defective may leak at the outputs. I opted for a DS32KHz module which worked out great. I gues there are more sensible ways to switch NIXIs.
It was mentioned in the email you should have received upon joining, if you provided a working email address. So it makes this not exactly a straight-forward proposition. They explain how the different types of logic ICs work, and how to use them by showing example circuits.
What about the timings? By cascading the Bit storages in a serial datashet we created a shift register. Other than the funky enclosure, most of the electronics are assembled from off-the-shelf modules. You can skimp on the base resistors, since only one transistor will be ON at any one time. 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 under uA in every example I have seen so a safe calculation for datasbeet worst case dissipation is 50V x uA or 5mW per channel or 40mW over the entire package.
Also two ways of switching the Nixie Voltage are discussed and as a bonus a closer look at the datasheet of the shiftregister is taken. The electronics and hardware assembly are also equally well detailed, should anyone else want to attempt to replicate his build. Truth Table for the, A and B Chip. A pressure difference usually around V V. I did not know about the HV so far. It could fail next week or in the next hour. Don leaves it up to the reader to follow along and build the example circuits so as to be able to see them working first hand.
By the way, this is what I settled on http: The additional zenerdiode you datasyeet is more a general thought, unrelated the the specific shift register. When it stops rotating, the pointer angle indicates the phase difference between the generator and the grid. There are 28 transistor drivers on that thing without the 6 digit option and all of the decade 1k55id1 need to be cascaded. Reminds me of a Geocities refuge. See what voltage is required to turn them ON, and how low the voltage needs to drop before they go OFF.
