Trigger Tube Clock

[Grahame]

Hi All

Here's two pictures of a nixie/trigger tube clock built by Massimo Capra
in Barcelona. Still to have a clear acrylic cover fitted over.

Details are here:

http://www.sgitheach.org.uk/nixie8.html

I have run out of PCBs but could be convinced to get some more
manufactured if there was sufficient interest - please PM me and I'll
gauge interest. It is unlikely I'll do any kits again. The design uses a
custom wound mains transformer that is not hard to have made. The Z700U
trigger tubes are available in their thousands from a UK supplier.

Note that the Z700U has a priming electrode so it doesn't have problems
operating in complete darkness.

Enjoy

No problems with the half life time of the doping of the ZM800U ? I can remeber somebody here in Netherlands who needed to check the ZM700U tubes in these, before he could make a well working clock.

What will those trigger tube prints cost?

Hi,

I don't believe the Z700U is doped. Its performance in the dark is
brought about by the priming electrode that keeps a good amount of
ionised atoms in the device so when the cathode-trigger gap is pulsed it
breaks down readily and reliably. I've not had any problems with the
Z700U in complete darkness whereas the XC18 trigger tube I tried to use
before that was a doped tube and was pretty useless in the dark. It
required light to keep operation reliable. I did try an experiment with
a Z700U with the priming electrode unlit and it then didn't trigger
reliably in the dark.

As for the price of a set of PCBs for a clock, it very dependant on the
number of people showing interest. Counting you, it make just two people
at the moment so I doubt if the price will be very good.

I would also be interested depending on price.

Grahame,

I'd be interested in a set of the boards myself.

Thanks,

Dave Speck

Beautiful! This looks like it needs a video on youtube....
