You asked: Are nixie tube clocks safe?

Are nixie tubes dangerous?

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.

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.

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.

Can you touch nixie tubes?

Yes! But be careful, touching any conducting part of your circuit can be lethal. If you are not familiar with working with mains fed circuits first read this. Examples of clocks which are fed directly from the mains are the Tube-in-Tube clock, my single-tube E1T clock, and Geert’s single digit nixie clock.

Do Nixie tubes burn out?

Nixie tubes are cold cathode devices and have no filament to burn out, so they have long lifetimes: a well-made nixie tube can last more than twenty years in continuous operation.

How much voltage does a nixie tube need?

Nixie tubes require high voltages (>170 volts) to illuminate. A single anode is connected to a high voltage source via a dropping resistor and cathodes shaped like numbers are grounded to make them illuminate. Drivers, then, must be capable of withstanding the driving voltage.

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. … For each 60 seconds when the tube is on (whatever digit), exercise every other digit for 0.2s.

What is a Nixie mermaid?

Nixie (postal), a piece of undeliverable mail, or the postal marking on such a piece of mail. Nixie, one of the three main mermaids in the first season of Mako: Island of Secrets.

What does Nixie stand for?

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

What is the difference between Nixie tubes?

The differences are the glass envelope shape and the ‘5’ and ‘4’ digits. IN-14’s use a upside down and backwards ‘2’ for the ‘5’ digit. IN-8-2 tubes have a narrower ‘4’ digit than the IN-14, but use a normal ‘5’ digit.
