Hi Eric,
That’s a good point. I guess it would not be too hard to construct a H-bridge
from 2x mpsa42 and 2x mpsa92
and drive that from the microprocessor, or even with one side using mpsa42 and
mpsa92 and the other side
just 2 resistors of ~100k between HV and GND.
Cheers, Frank

Some of the Russian users over at Radiokot.ru have discussed this and
similar circuit arrangement, like for the IN-24 here:

Hi Martin,
Yes, the top one is in fact an H-bridge.
The 2nd circuit is as good as the first, it only consumes a tiny
bit more current. I’d favor the simple circuit, quite a reduction
of parts which makes the H-bridge look a bit over the top.

Easier yet, just use two

I can do you E12 series from 1M to 10M as 5% 0.25W - so would need
values in series to get what you want.

I don't think that will work. The resistor will effectively short out the
resistor/neon combination. It won't light in either direction.

Ok, I can understand that. You could try a royer converter. The fun is in the
making
of the small transformer.

One transistor is on at a time, pulling that end of the neon down to
(approximately) ground, basically overwhelming the resistor on that end. The
other
That's exactly what I intend to do, however a little bit more sophisticated:

Usually when someone refers to a Royer oscillator, they mean a resonant Royer,
which has a series inductor and resonating capacitor, and produces a sine wave
output. The wikipedia article (like many such) is somewhat misleading, and

What a great link! It's fun to see what fellow hobbyists are doing, and
the translation of the web page makes it so much easier! Since I am a
sucker for any new Russian nixie related stuff, I did a search on E-bay for
the IN-24. I found some, and therefore ordered a few. Hopefully the
Thanks for the link! Nice to see Russian hobbyists using their own tubes.
:-) I had not heard of the IN-24, so I did an E-bay search, found some,
and ordered a couple. Looking forward to playing with these too.
