With separate clock lines, you can eliminate the timing problem between
cascaded HV devices. I attached the timing I use for my clock (havn't
had a chance to test it yet; the boards just left the PCB vendor... yes I'm
getting anxious to try it out!).
If you are using direct-drive, there's
re Hi-z meters.
A useful measurement technique is to provide a variable voltage approximating
the voltage that you wish to measure.
eg Potentiometer across a bench supply, with a common to the circuit under
test..
You connect you meter between the point to be measured in the circuit under
Hi Marcin,
Nope, that's the Eagle PCB file, what I'd like to find is the Eagle
schematic - SCH extension. I'd like to make them both available in my blog
post.
Phil, probably I won't be selling kits. The sockets are probably harder to
obtain than ZM1000s themselves. I have counted the
I took another look at the level-translator circuit, and I noticed there is
a resistive pulldown (10K). This could be the problem, but without any
scope traces I cant be certain. You could do a SPICE simulation and get a
decent idea what the timing is.
The CLK on the HV5622 is falling-edge,
Hi to all!
Ten years ago I build a clock with ZM1000 nixies and posted a few photos of
it in the old Yahoo neonixie group. I recently decided to revive the
project: http://betatronics.blogspot.com.
The thing is: I have lost the schematic file for this clock. (Loss of data
and no backup, of
Damir.. any chance of buying a kit less Nixies - I have lots of ZM1000's new.
Thanks Phil

Well, I inspected the power line to the HV5622 with the oscilloscope and it
shows a straight 12V line, no noises. On the clock line, I do sometimes see
to have longer rise so it could be a problem I guess.
I have made the second version of the board with 4505 level shifter, both
Vcc and
