A couple of points.
You are going to need more than 0.2-0.3 mA to fully light a nixie
tube. Otherwise, you will see gaps in the numerals.
A camera flash power supply has DREADFUL efficiency, is usually
designed to work from a 1.5V battery, and does so by pulling HUGE
currents - often over 1 amp.
I have picked up a few B-7971 supertubes and whilst I have Jeff, Pete and
Jurgen's wonderfull 4LW quietly swearing in the corner - I yearn for a
clock/message board with maybe 8 or more of these tubes with a clock
function but also a scrolling message feature with a computer link to drive
it.
Thanks for your reply guys!
And so I have gave up on my current supply, and decided to make my
own. I didn't want to make my own as I thought that it will be the
most expensive option, but I was wrong.
Seems like all these pre-made supplys are around 20 bucks, a bit less,
and for that kind of
Also, does anyone know the shematics of this supply? (

It is incredible how I
I bought one of these in the link above and like it. If Lance still sells them.
I use it for bench testing/proto work. It's adjustable which makes it nice for
certain apps. John Taylor www.tayloredge.com has a real nice module that's
pretty much plug and play and works real well also

I'm putting the finishing touches on a new batch of B7971x8 driver
boards. Please have a look, and if you are interested go to the store
and put yourself on the notify when back in stock list. The wait
won't be much longer.
That little simple 555 circuit is fairly standard and basic, and
will work. It wont give top performance, but who cares? Stick closely
to the advised components, particularity for the main FET, switching
diode (NOT a IN4007 clone!) and inductor. Keep the layout reasonably
compact.
