Sir Nixie Bunny
I have one of your 10 year old Burroughs Nixie clocks. Is there any chance
you would upgrade the FW to include the "slot machine" affect? I only
replaced one tube in about 9 years
I'll pay of course!

The S11S1 is an experimental tube that combines an E1T with output
electrodes for all ten stages!
Just have a look here and marvel at the mechanical construction:

I'd love to have a few of those to build a clock with!

@gregebert: Yes, I ordered a switching regulator. The 6.3V AC just happens
to be available on the transformer I am using for other purposes.
@jfeng: I am tending to agree that an isolated 5V power adapter is the way
to go, particularly as I will want the logic circuits to stay functioning
even
If all you want is to get 5Vdc rom the mains, a USB charger seems like a
very attractive option. They are usually less than US$5 and occupy about
1cu in (plus the power plug). My initial concern would be safety
isolation, but some of these will surely be UL listed or CE qualified.
However,
I tend to use higher voltage transformers, in the 8-12VAC range, full-wave
rectifiers + filter-cap, then use switching-regulators that are
pin-compatible replacements for the popular LDO regulators. They are 90%+
efficient, and therefore generate almost no measurable heat.
If the current is
And I’d ask about mains stability.
Was half-wave ruled out?

I would use four discrete schottky diodes in a bridge, and a low dropout
regulator like an LM1117. The 5V version of the LM1117 regulates down to
6.2V input and delivers 800mA.
