Mercury is also present in reasonable quantity in fluorescent tubes,
of which there are millions all around us.
Hi,
personally I think that the IN-18 Blue Dream and the Sven Nixie
clocks cannot be compared, for several reasons:
First, you already mentioned the IN-18 tubes, they are much more costy.
But this also poses a technological problem: While it is rather easy to
supply 12mA = 6 * 2mA for IN-14
During my Nixie tube project mercury will be a good solution for
prolonging the tubes' lives. When I merely mentioned the possibility
while talking to our facility manager, he wouldn't want to listen to me
anymore, and I had to assure that I would not tinker with mercury in
their rooms...
Personally I think that the whole mercury craziness is plain stupid.
But well, people were made to believe that some plants are evil.
What if you tried to do it as The Ancient Nixie Makers would do: Use a
tiny mercury giver tube. Maybe it would be possible to find them in
the 'former USSR'? Or
You mean that if they were 1mx1mx1m with 1m3 of mercury it would be
fine? World is weirder than I thought...
I would just use them not telling anybody what's in those tiny, tiny
tubes. Or tell them it's getter.
Then you crack those tubes open in some other location. And you are
not exposing
Sure, 1m^3 would be fine ;-) Don't worry, in that case other rules will
kick in...

I think it's a great clock stuffed full of features and would really
like one but I too think it is on the expensive side. 179 Euro (inc
tax I'm in the UK) just for the board kit + you have to buy the needed
transformer @24 Euro + the colons @19 Euro separately! Surely a
critical part

That's what I was thinking, it was my understanding that elemental
mercury is not all _that_ readily absorbable by the body. The kind that
you need to worry about is the sort that has already been absorbed by a
body (like a fish) and so is in a form that your body will happily
accept.. and
OK, you are right, it's a matter of taste.
