I've just received a lot of IN-28 tubes.
Now I'd like to drive these using only AC 230V mains but can't get it to
work the way I want.
The tube has 3 connections: anode, cathode and screen.
To get it to light up using the anode and cathode you need 340V so that's
not going to work. But using the
I should also say that they will light up with 250V DC reliably, so I'm
pretty sure that 340V is full-wave rectified AC

A late friend of mine who was quite a nixie addict.
He was inches away from flying to Europe for a set of CD47s before the deal
fell through. He was no less 'particular' about nixies than the nuttiest
among us, and had spoken with many folks (I don't know any names) while on
the hunt for these
Hello,
Does anyone here have any tested data on the maintaining voltage and
current requirements for these panaplex displays?
Tube-Tester suggests 150V and 0.35mA - which for a 170V supply suggests
(170-150)/0.35 K = about 56K. If I use that I measure the voltage across
the illuminated segment
I am in possession of two watches from Cathode Corner.
One is the round version with a black case, the other is the square
version, also in a black
case. The round looks like the same model that has been seen 'on the wrist
of a certain computer geek'.
I believe that the owner of these was
I've always felt that the two critical parameters for neon displays of any
kind are the operating current and the striking-voltage. Whatever voltage
you get across the tube/bulb when it's operating at the proper current is
not important. Basically, "it is what it is". This is why I use
That seems like a sound plan - I shall stick to the recommended segment
current then via whatever resistor is required - in this case it seems to
be fairly well established that this is 350uA per segment and then around
180uA for the decimal points.
I have no knowledge about current limiting
Connect a ~ 1M resistor from the anode to the grid. Use fully rectified
mains, which should give you the 340V (240*1.414). Feed that in to the
anode with your resistor, and tie cathode to 0V.
