Please note that this applies to ALL Yahoo Groups, as even those who elect not to receive any email from this group will appear in our Bouncing list if their emails from any Yahoo Group are being returned as undeliverable.

If you completely omitted the limiting resistor, your nixie would have datasneet VERY short and eventful life.

If the code is extremely optimized you may run into problems and if you’re running Because of this, all we care about is the sinking capacity because of our usage in this case; the transistor should be able to handle the load fine, voltage is irrelevant.

I guess this is what I get for writing rants late at night: Dataasheet new topic will begin with this message. Tip A useful dataaheet insightful technical note on component selection, circuit design or testing etc. Those books even show the basic internal transistor circuits used to make the gates.

Also, it’s a bugger to debug i155id1 you’ll need an isolating transformer before you can use a grounded scope on it. You can only get old stock which has been lying around for decades.

When holding the button for longer than one second you come back to the free- running mode. Well that is a close one on this uC. It could fail next week or in the next hour. One wrong move and he would have ended up with a piece of aluminum junk and a missing face panel. Reason Report to Moderators I think this message isn’t appropriate for our Group.

A useful or insightful technical note on component selection, circuit design or testing etc. I have found larger tubes are fine but smaller tubes can be borderline. Navigating a somewhat clunky old website to find them is well worth the effort.

A few blue LEDs add a bit of ambient light. There is still room for improvement, especially with the sensor mounting, but for now, [badjer1] seems pretty happy with the result. A pressure difference usually around V V. 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.

We really love the understated laser-cut black acrylic case. By cascading the Bit storages in a serial way we created a shift register. Nixie Tubes have an anode voltage of around V.

How Does it Work?: The KID1 and the 74HC

I gues there are more sensible ways to switch NIXIs. I sat down and sketched a “super simple” driver- testing circuit to test them all. After building that once, you’ll decide that a microcontroller design is less work and xatasheet flexible.

Crosscheck the recommended values. These are mostly intended to connect to the inputs of chips of the same ‘ilk’. This will protect the chip, but is bad for the circuit, since an undesired output, will be partially ON, and maybe visible.

I’m serious, what is the answer? Truth Table for the, A and B Chip. He also assures that you will know not only how it works, but how to build things that work reliably over the long term.

Want to add to the discussion? That chip’s output transistors can’t tolerate a voltage much higher than that.

The required anode resistor takes up the slack, by having the remaining 40V V supply – V nixie drop across it.

The ZM tube is driven with 2mA current. Ok, so here is my predicament: I will use it for all my clocks k1155id1 the next future because you need no other parts around it! This one resistor limits both base current, and collector current, to a maximum of 4. To get current flow, there has to be a pressure difference.
