Since the 5V contact coming from the regulator remains constant, that would
suggest it is not overheating/shutting down, right? I'm in contact with
Pete (very nice how he is willing to answer questions from people who abuse
his products, lol) but I've also gone and ordered another board. I don
What's important is ic2 receives power from the 5v regulator . The
oscillator is connected and drive + hv sense is connected to the rest of
the circuitry. If those check out (continuity) and the FET is not shorted,
but something is still causing the 5v regulator to overheat and go into
shutdown, li
Obviously. That said, what little I've learned has been in the process of
troubleshooting here, so my ignorance wasn't very useful, either. Which is why
I'm working to fix that.

You say it better than I, but I simply mean that the fact I read 12 at the HV
point means it is the FET circuit or earlier with an issue, so that eliminates
all the downstream stuff from troubleshooting for now. Thanks for the
explanation of the FET amplification, I understood it involved oscil
Hi Dalibor
I used the Pebeo Vitrail colours with IV-9 numitrons, also by dipping, and
it worked nicely. It did require some testing and dilution of the colours
to achieve the effects I wanted, so you might want to try on some small
test tubes before committing one of your lovely large tubes to
Truly beautiful! The price though is indeed enough to render one speechless
a second time...

A little knowledge is a dangerous thing.

Dalibor, I had success with IN18's (thanks to Michael Barile for helpful
advice) dipping the tubes in Pebeo Vitrea glass paint (make sure it's the

Hello guys,
I remember I read a post in the forum where someone showed a DIY red
filter on a nixie tube. I was searching hard, but I havent found it
again.
I am going to try making a red filter on my tubes, so I am looking for
tips and tricks first..
Any tips for a colours I could use for making t

The only thing different with the IC2 (driver, vs. nixie-lighting) present,
is that the 5V across the LEDs slowly dies off (I assume because of an
additional trickle ground connection within board that is in front of the
actual LEDs). The 5V and non-amplifying 12V test points do not change
whe
HV sense resistors are all good? Have you tried it out with the driver IC
removed? If that's all good and the FET is not shorted, might be an issue
with the microcontroller.
