I ran into the same problem with the 10's digit in the hour position.
When it's dark, it takes extra time to turn back on. I put a 22 Meg
resistor from the decimal point to ground. This primes the Nixie
without turning on the DP (it glows very faintly), and it turns on
without the delay.

*Its been a long time since I built the wonderful Jeff Thomas WWVB Radio
Controlled Nixie Clock. I was never able to get the modified Quartex module
to get a reliable receiver lock to keep the time accurately and I
reluctantly retired the clock over 5 years ago. Recently however, I was
Hi,
I did just that, not for tube life but because I live off the grid and need
every watt I can make. I used an IR sensor from Parallax and interfaced it to
an MCU. Nice thing for me is the clock is MCU driven, so all I had to do is add
a little code. It's nice to do it with a MCU because you
How do you make your watts, Jonathan? Just curious.

Hey there,
I have a similar plan for my work-in-progress clock. What I'm
currently planning on doing is using a PIR sensor I ripped out of a
really old motion detector in my house to allow me to use short-range
motion detection. For some reason, the sensor seems to have a very
erratic output
Clever. One thing I was thinking of doing was putting a small ~400nm
LED under the tubes and turning it on for a few microseconds while the
tube started up, but your way is more sensible.

Wait... if I have a 10k resistor on the high side and a 10k resistor
on the low side, won't the voltage at the base of the MPSA92 just
hover around 85v? Is this low enough to turn it on? Also, 20k shorting
between ground and +V and ground will draw 8.5mA, won't it?

I don't have any capability of programming AVRs etc. I can just
solder.
I need to be able to switch off the 9v wall adapter supply to the step
up transformer. See schematic here:

Well, what about just switching it on/off? Or use an off-the-shelf mains
timer (- electronic or mechanical) ?
Or, there is home-automation equipment [X10 etc] that will allow you to
operate a mains-switch from various remotes.
