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. Please see this excellent article on Wikipedia about nixie tubes.
What voltage do Nixie tubes work?
170 volts
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 happened to Nixie tubes?
Nixie tubes were superseded in the 1970s by light-emitting diodes (LEDs) and vacuum fluorescent displays (VFDs), often in the form of seven-segment displays. Also, LEDs are much smaller and sturdier, without a fragile glass envelope. LEDs use less power than VFDs or Nixie tubes with the same function.
Why are nixie tubes so expensive?
The reason is that nobody is making nixie tubes on a commercial basis nowadays. 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. The thing is that tubes were not popular in clocks until recent years.
How to increase the voltage of a Nixie tube?
A single inductor can typically give you in the order of a 10x increase in voltage. It seems obvious that one way to go higher is to use a transformer. i.e. let the transformer boost the voltage generated by the back-EMF. Apparently, these are called flyback transformers.
What kind of signal does the IN-9 nixielyzer show?
The IN-9 Nixielyzer is an analog audio spectrum analyzer, based around an analog bandpass chip. It offers the display of six selective audio bands: 63 Hz, 150 Hz, 330 Hz, 1 kHz, 3.3 kHz and 10 kHz. As a feature, you can mix the signal of a build in microphone, to use the IN-9 Nixielyzer as a stand-alone device when no audio source is connected).
Can a build in microphone be used with an IN-9 nixielyzer?
As a feature, you can mix the signal of a build in microphone, to use the IN-9 Nixielyzer as a stand-alone device when no audio source is connected). Both signals (RCA and 1/8″ TRS are only internal mixed via an electronic zero ohms node and do not affect each other.
What kind of FFT does the in 9 nixielyzer use?
The IN-9 Nixielyzer uses no digital signal processor or FFT (Fast Fourier Transformation); so the display is stepless and fully in realtime. Furthermore a modified dbx compandor ciruity was introduced to enhance the dislayed dynamic range.
