[neonixie-l] Dekatron Clock kit

[Jack Buechler]

Has anyone got or know of a place that offers 6 or more digit Dekatron Clock 
kits?

[Nicholas Stock]

Not a small amount of money spent there...I recognize most of
themexcept the dekatron clock and the LED matrix one (which looks super
cool!).

Thanks for sharing!

Re: [neonixie-l] Re: Gray version of our NL-8971 clock

[Bill Notfaded]

I wish I could because I know you really wanted one too.  Actually if it
hadn't been for Michael B. I wouldn't have any tubes.  It seems like this
person in NY/NJ area was only one I've ever heard of ever having B-8971's
and they sold them all years ago.  I'm surprised these recent planar tubes
appeared all of sudden.  Either a find somewhere or maybe someone with a
stash died?  I'm sure Pete isn't telling ;^} and I don't blame him.  His
price wasn't that bad for good tested planars really considering the
rarety.  I almost bought a set but he only had 5 left.

[Michail Wilson]

Bill,

 

I’ll give you 2x B-7971 clock kits for your B-5971 completed clock.

 

I’m pretty damn sure you’ll say no, but I had to propose it.

I'd be interested in a B-7971 version Michael!  There just aren't any tubes

Re: [neonixie-l] Re: Homebrew high voltage nixie power supply

[Kevin A.]

Richard; If you could provide a few images of your setup and the wiring
specifically, that would be very helpful. I'm not sure how your grounds are
routed, but using several switching power supplies without adequate
grounding could cause that switching noise to couple through other parts of
your circuit.

Another problem I see is using the $2 buck converter to directly power the
logic. It provides little in the way of filtering and low noise output; it
would be perfect for preregulating 12 volts to 8-6, but then using a linear
regulator for a low noise 5 volt rail, which should alleviate power related
glitches occurring with the your control logic.

[neonixie-l] Re: Gray version of our NL-8971 clock

[Bill Notfaded]

I'd be interested in a B-7971 version Michael!  There just aren't any tubes 
around really... I wouldn't want to rob my greenie for this!  I've got 
B-7971's though.

I'll buy some I'm a numitron guy... how many depends on the price.

RE: [neonixie-l] Re: Homebrew high voltage nixie power supply

[Bill van Dijk]

Richard,

 

Adding caps is not likely to improve things since your ripple current will 
increase, and only serve to make things hotter. If you suspect the caps (very 
possible) just replace them with the same value.

Hello,

 

I scoped the 5V and it all looked just fine, I am using the same 12V Buck 
converter that I have used everywhere else - I will try adding caps next.

 

The 12V supply is capable of delivering much more than the required current and 
it is also driving a 6 digit B-7971 device at the same time

 

I removed the HV enable/disable line - no difference.

 

I will report back once I have added some capacitors.

Richard,

 

The phenomena you describe seems to be quite interesting, and after thinking 
though the possibilities I have several ideas for you to try:

 

The 2 most likely scenarios I can come up with would be:

 

- Switching noise entering from the enable pin to the microcontroller. Try 
leaving the enable pin unconnected, and the power supply will stay on. If you 
find that this alleviates the problem, you can use an optocoupler to drive this 
pin and keep it galvanically isolated from your microcontroller. 

 

Or:

 

- Noise or large voltage ripple present on the 5V rail. I'm not sure which 12 
volt power supply you are using to drive the whole system, but the introduction 
of a large switching power supply could be taxing your 12 volt source and/or 
introducing unexpected noise. If you have a scope, see if you can probe the 12 
volt line and the 5 volt line with the NCH device installed, and then with the 
new power supply installed. If you see a lot of noise or higher ripple with one 
versus the other, try to smooth things out with some general purpose 220 or 
470uF electrolytic caps placed close to your circuits across power lines.

 

I would also recommend using a linear regulator for powering logic such as your 
micro and the smartsocket controllers. You can pre-regulate 12 volts down to 
8-6 volts, then use a high quality LDO (low dropout regulator) to provide clean 
power to your logic circuits. Switching power supplies can be very noisy and 
cause glitches just by output ripple present in normal operation. 

 

My suspicion is that the larger switching currents of the big supply may be 
inducing some noise on the low voltage side of your circuits, and seeing as the 
5 volts is running directly off of a switching supply this noise is making it's 
way to the logic and causing glitches. You already tried moving the power 
supply away from the smart sockets and observed the same glitches, so I cannot 
imagine EMI/RFI emitted from the device itself is the issue. 

 

Of course, let me know what your findings are. We will solve this!

Just got to my desk after working away and have looked at the PSU's.

 

First test - connect to 12V and set the output to 170V   all good.

 

My clock build has ten ZM1350 smart sockets - though only using six at the 
moment - it has been running reliably for 1 month or so using one of the 
NCH6100HV power supplies to generate the 170V.

 

I removed the NCH device, mounted the new supply, connected GND and 12V on one 
side, then the 170V Output and the output control on the other side and fired 
the thing up - all looked good.

 

I have now had it running for almost an hour now and I am seeing some odd 
behaviour on the smart sockets in as much as occasionally some characters are 
corrupted or the seconds misses a single change (ie, displays 1 then 3,4) other 
characters display garbage and some transition effects change.

 

I have checked all voltages on the Smart Sockets and right now - the 5V is at 
4.995V and the 170V is at 169.9V so I would expect that to be OK for the logic 
and the display.

 

The display blanking (processor disabling of the 170V output) is working 
perfectly - I am just getting corruption.

 

I have NOT connected GND on the output side as it appears to be the same 
connection as GND on the input side.

 

I have a small BUCk converter generating the 5V for the logic and that line 
appears to be clean.

 

I have mounted the new HV supply on one side of a perspex panel on 15mm 
standoffs, the smart sockets are on the other side of the panel with the same 
15mm standoffs.

 

Is there any risk that some form of RFI is causing the issue that I am seeing?

 

I removed the PSU from its mount and moved it away from the smart sockets - 
around 20cm and the symptoms remained.

 

If I put the NCH6100HV back in the circuit then order is restored.

 

Could you suggest where I should be looking next?
