Are Nixie tubes efficient?
Efficiency ranges from around 65% for 3.7V in, up to around 80% for 5V and 12V.
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 current does a Nixie tube draw?
This results in an average current draw of about ten microamperes. The nixie display tubes require about 180V to light up (strike) the neon gas and about 140V to sustain the orange plasma glow. This high voltage is provided by an LT1308B flyback-mode switching power supply controller chip, U1.
How long does an in 14 Nixie tube last?
Overview of Soviet (russian) Nixie Tubes types: height, what they display and their life expectancy
|Type||Height of digit||Life time|
|IN-14 (ИН-14)||18 mm||min. 5000 / 12 500 h|
|IN-15A, IN-15B (ИН-15А, ИН-15Б)||18 mm||min. 1000 h (A) / 800 h (B)|
|IN-16 (ИН-16)||13 mm||min. 5000 h|
|IN-17 (ИН-17)||9 mm||min. 7500 / 9000 h|
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.
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 clocks safe?
Yes, it is safe to power nixie tubes all the time, the power consumption is below 1W per tube, they stay at room temperature. 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.
Are Nixie tubes 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.
What is a Nixie Watch?
It is a two-digit wristwatch using Nixie tubes, a forty-year-old display technology that is delightfully easy to read. The watch requires no button-pushing to operate. 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.
