I actually designed and built a FLW clock out of IV-4/IV-17s; they’re quite
nice little tubes and currently still reasonably easy to get on the e-site.

And here’s a short movie of an older version of the clock “walking the
tree” as was
this in
a while, but I remember that it worked for some funky shaped
oscillators and things that I took out of an old motion detector a few
years back.

Hi all,
I'm in the process of building up a little four-digit NL-5440A clock,
and I had the good fortune to find a small bag of SK-185 sockets that
mate with this particular tube. If you're familiar with the NL-5440A,
you'll know that the pin spacing on the bottom of the tube envelope is
quite
the chance.
The AVR codebase, EAGLE libraries, project files, and host-side
interface code are all currently available at http://www.github.com/koolatron
-- I haven't pushed to the repo in a little while, so the code is
likely out-of-date, and there is no documentation as of yet.
