I often use a classic 555 nixie power supply as I find they always work for me
and are very tolerant of any PCB layout abuse I submit them to in my infinite
ignorance.
My question is: Is there a simple way of switching a 555-generated timer off
from a 5v logic gate, as I would like it to go to

Hi John,
I use the attached circuit in my ZX81 nixie clock and works great. On J7 pin
1 is the 12V input (mine is 9V btw). Pin 2 can be pulled down to gnd with an
open collector circuit which will then power up the 555 circuit. The

With this 555 power supply, is it ok to use a 9-12V wall adapter
directly into the circuit, or would a voltage regulator first be
ideal? I figure it IS a voltage regulator so thats not necessary but
then again for all I know it would be better to

In Denmark, you can buy from RS being a private customer, but you need to do it
online if is't not in stock locally.
We have a local warehouse in Copenhagen, and if it's in stock there you can
pick it up at the counter and pay by cash, but if it's not in stock, you'll
have to order it online
I've made up dozens of these supplies in all kinds of layout
configurations and have found them to be bomb-proof. In fact I have
never had a failure yet, they work every time. The circuit will work
without the snubber R6/C3.
There must be some simple answer to your problem. It seems to me
