How To Make Nixie Tubes

How a nixie tube is made?

The glass tube contains a wire-mesh anode and multiple cathodes, shaped like numerals or other symbols. Applying power to one cathode surrounds it with an orange glow discharge. The tube is filled with a gas at low pressure, usually mostly neon and often a little mercury or argon, in a Penning mixture.

What are Nixie tubes filled with?

(Numeric Indicator eXperimental-1) The first electronic digital readout. Developed by Burroughs in the 1950s, a Nixie tube is a vacuum tube filled with neon that contains 10 wires formed in the shape of the digits 0 through 9. The wires are attached to cathodes on one end and a wire mesh anode on the other.

Do they still make Nixie tubes?

The last nixie tube was made in the early 90s, when this beautiful technology was replaced by lower-cost alternatives. But production has now resumed in the Czech Republic.

How long do in14 Nixie tubes last?

Newer Nixies such as IN-8, IN-12, IN-14, IN-16, IN-17 and IN-18 have a specified lifetimes of about from 2000 to 12 500 h. This is probably caused by the addition of mercury, which limits evaporation of the cathode material and prevents cathode poisoning.

Are Nixie tubes rare?

Today, nixie tube clocks are still available but rare. People who make them usually use Soviet military stocks. As old tubes get used up, they also become more expensive. The tiny tubes used in watches are especially rare because they were rarely used in the nixie display age.

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.

Who is making Nixie tubes?

Nixies Reborn: This clock features modern-day Nixie tubes made by Dalibor Farny. The Czech engineer has revived the manufacture of the distinctive display devices, which had their heyday in the late 1950s and 1960s.

What Nixie means?

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

What is a Nixie mermaid?

The name, Nixie, refers to a magical water creature similar to a mermaid called a Melusine or Neck. The Melusine are often depicted as having two tails. Also, Nixie is the name of a different Germanic mermaid shapeshifter and water spirit.

How do vacuum tubes use neon?

Neon lights, also known as cold cathode fluorescent lamps (CCFL), work when electrodes on each end of a vacuum tube filled with neon or other fluorescing gas are subjected to an alternating current, according to the Edison Tech Center. The current ionizes the atoms causing the tube to be filled with free electrons.

What is a vacuum tube radio?

A vacuum tube, also called a valve in British English, is an electronic device used in many older model radios, television sets, and amplifiers to control electric current flow. The cathode is heated, as in a light bulb, so it will emit electrons. The anode is the part that accepts the emitted electrons.

Are Nixie tubes reliable?

The accuracy of the Nixie clock is thus locked to the accuracy of the hydrogen maser. The stability of this maser is around 4×1015 at 1 day making this the most accurate Nixie clock on the planet. The ‘scope clock in the right is directly driven by the maser’s 1 PPS output.

What are the smallest Nixie tubes?

IN-17 – Ultra tiny nixie tube. IN-17 is cold cathode neon gas discharge indicator intended to display Arabic digits in a shape of “0 1 2 3 4 5 6 7 8 9” . Digit size approx 8 x 5.5 mm (H,W). There are normal “5” (not an upside down “2”).

Are Nixie tubes waterproof?

It is a two-digit wristwatch using Nixie tubes, a forty-year-old display technology that is delightfully easy to read. Just hold the watch at your standard viewing angle, and the hours, then the minutes, will appear in perfectly-formed, 14mm tall, glowing orange digits. It is water resistant and rugged.

Do Nixie tubes use AC or DC?

The overall circuit is powered through an off-the-shelf low-voltage AC-to-DC adapter. This version will use the IN-12A Nixie Tube design.

How do you wire a nixie tube?

Connect the cathodes of your Nixie tube to the corresponding pins on the SN74141 and connect the the anode of the Nixie tube to 180vdc+. The IC chip takes a binary input on D, C, B, A and outputs the corresponding digit of the nixie tube. Low, Low, Low, Low for 0. Low, Low, Low, High for 1 and so on.

What is a divergence meter?

In the Steins; Gate anime plot, the divergence meter is a Nixie1 clock/calendar set by the protagonist to show how much an original timeline has been altered by the influences of time travel. Its blue dots are the original events in case the divergence meter is equal to 0, that is, the time machine was not invented.
