Best answer: Can you make a nixie tube clock?

How long do Nixie tube clocks last?

Average longevity of Nixie tubes varied from about 5,000 hours for the earliest types, to as high as 200,000 hours or more for some of the last types to be introduced. There is no formal definition as to what constitutes “end of life” for Nixies, mechanical failure excepted.

Why are Nixie tube clocks so expensive?

Clocks and watches are so expensive not only because of the tubes but also because of the high voltage supply. Nixie clocks require extremely efficient components, and you have to pay for them, as well.

Do Nixie tubes use a lot of power?

Although the voltage is high, the amount of current flowing is very small, so the clocks do not use much power. They only consume about 3 to 4 Watts of power, and consequently generate almost no heat. The tubes are not hot or even warm to the touch.

What voltage do Nixie tubes work?

Tubes ignite at 140-170 V, slightly varying by type. Once ignited, their resistance is very low so a series of resistors is necessary to limit the current, typically to 1-5 mA. The operational voltage of the Tube is 90-130 V depending on type. If the voltage drops below the turn-off voltage, the Nixie will go out.

Are Nixie clocks a fire hazard?

Our clocks are powered from power adaptor which is able to deliver only 24W, in case of short-circuit of any kind in the clock/tube, the power adaptor cuts off the power. No risk of setting surroundings on fire.

Why did they stop making Nixie tubes?

In the 1970s, Nixies were eclipsed by LEDs, which were not only much cheaper to make and use but also more versatile. The tubes might have died the lonely death of countless other obsolete devices—and yet they did not. Some Nixies lingered on in legacy equipment, of course.

Are Nixie tubes toxic?

It’s somewhat safe but potentially lethal. I tested everything with a meter and shorted all leads together to make sure mains are off. Be careful and think twice before you do anything.

Are Nixie clocks safe?

Are Nixie Tubes Safe? They are completely safe. Just do not stick your fingers inside the the clock or you might get shocked!

What does Nixie mean?

noun. a letter or parcel that is undeliverable by the post office because of a faulty or illegible address.

Are Nixie tubes efficient?

Efficiency ranges from around 65% for 3.7V in, up to around 80% for 5V and 12V.

What is nixie tube poisoning?

Nixie tubes tend to develop a phenomenon called “cathode poisoning” on digits that are no in regular use. To make sure the digits in your clock stays in good condition, all of them needs to be exercised regularly. This is done by running a “cathode poisoning prevention routine” regularly.

Do Nixie tubes use AC or DC?

Nixie tubes need about ~180Vdc to light up and thus on most devices, a DC-DC converter is needed. Here we designed a simple DC-DC switching regulator capable of powering most of Nixie tubes. The board accepts 12Vdc input and gives an output of 150-250Vdc.
