I am just occupied to develop a ac driver to supply neon bulbs symmetrical.
Those simple neon's with only two rods as electrode are awful on dc.

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

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

Hi Frank,
That's even better as I have in mind. However, I am busy to make a dc - ac
converter. I need it for an other project, where is no hv in use (meter clock).
I want to use neon's to avoid LED's because of old style.
Later more.

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

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

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.

I bought 1,000 of these and conditioned a whole bunch of them for a ring
counter clock. Many of them started to flicker and develop bad habits. I think
they are just not very good neons.
