Nixie tubes are cold cathode gas discharge tubes with multiple elements. Elements are typically in the shape of numbers from 0=9, or mathematical symbols. Elements glow orange when high voltage is applied between the anode and one of the cathodes.

Driving a filament
What to do really depends on your power budget and physical size of the circuit.
The brute force approach is to linearly drop the 5 V to 1 V. You say the current is 50 mA, so that will take a total …

Reducing the brightness of Nixie tubes
This simplest way to reduce the brightness given the existing circuit is to reduce the high voltage. The brightness will be non-linear with that voltage, but you should be able to find a point that h …

Anode driver for Nixie clock
That amount of current should be well more than required for normal nixie tubes.
The load on the digital output is the 1 mA divided by the gain of Q1. …

Is this circuit OK for a Nixie Tube clock?
I haven't really tried to follow your circuit, but this doesn't make much sense:
You say something about a 12 V interface, but the transistors are used as emitter followers. Not only will that dec …

Alternatives to High Wattage Resistors? (Do multiple low-wattage resistors equal a single hi...
Yes, you can make a high power resistor from multiple low power ones.
The simplest way to do this is to put them all either in series or all in parallel. With N resistors in series, make each 1/N th …
