I remember that clock! - I seem to have more than 10 Nixie clocks, however
I would be interested in the new version...

Before I let the magic smoke out of half a dozen MAX1771 ICs.. has anyone
ever tried using ceramic output capacitors? It wants a low ESR capacitor,
so ceramics may work well.
The datasheet doesn't mention ceramics on the output side.. but then again
it was written a few decades ago when the
I'm going to make this one a single board using the Z573M/Z574M tubes,
since I have enough for a batch of kits.. but yes, I have in mind something
more modular later.
I'll look into the feather. I've heard of it, but never tried one. There is
plenty of prototyping space.. so I'm sure it can be
You obviously can't just have one!

Excellent stuff Moses! Will you be releasing plans/open sourcing things? Just
curious.
Cheers,
Nick

Nick,
I'm glad you like it! A good deal of time has gone into it so far.
I'm definitely going to open source the ESP32 code, it's written in the
Arduino IDE and is turning out nicely. I'm sure people will add to it and
have uses for it other then a clock.. counters, etc..
I haven't started on
Hi Moses,
What David writes below about the capacitance reduction of ceramic capacitors
is correct.
I have experienced success using polymer aluminium electrolytics (solid
electrolyte) to replace conventional low-ESR electrolytic capacitors that
regularly fail in similar applications.
You
I haven't tried it, but I can make some observations. The MAX1771 isn't
connected directly to the output circuit, so it's not likely to suffer from
a problem. The current flows through the inductor which will accommodate a
momentary short circuit caused by the capacitor.
In short, it shouldn't be
Thank you. Yes, I almost forgot about the DC bias voltage :(

You are right, most of the ceramic caps I was looking at don't publish any
data on decrease due to DC bias. I may try it
Roger,
Yes. Looks like the common dielectrics (X7T, X7R) available in the 250v
1-3uf range suffer from a 30-80% reduction in capacitance at 180v. I hadn't
realized it was that high.
Thank you, I'll look at the polymer caps. It's my last remaining
electrolytic on my board and if possible I
