Attached is a short account of a most pleasant afternoon spent in the autumn sunshine having a ramble-chat and so much more over a cuppa at the Puffing Billy:)  Many thanks to Neil, Andy, Rob and Patrick for making it a success.

It was a most excellent afternoon, but bad for the wallet - I'm now
scouring ebay for Siemens smallest nixies :-)

Oh dear. What have I done? :-)

They can be compulsive. As I sit here there are 3 Nixie clocks on my desk, 3 more in the living room. One in my wife’s office. Another by the 3d printer...

This seems bad enough, but I was corresponding a few weeks ago with another nixie clock maker in the US who admitted to 27 clocks!  You have been warned.

The top ones are Russian nixies made in 1979. The middle are Siemens brand no datecode but 1980s I think. The bottom clock uses 14 segment tubes made by Burroughs in the USA in 1964. All the electronics is modern and microcontroller based, though having said that the bottom clock is over 20 years old.

As soon as LED and LCD displays came along nixies fell out of fashion as they need a supply around 170v. It's amazing how many are still around for sale on eBay though, particularly from former USSR countries where they continued to be made even into the 1990s.
