Re: [neonixie-l] Pricing Insanity

2019-05-12 Thread 'Greg P' via neonixie-l
Jeff,

That is still the going price.  There seems to be an endless supply of 
Z566M and IN-18's out there.

Re: [neonixie-l] Anode current and voltage measurement

2019-05-12 Thread Bill Notfaded
This is interesting to me because the current baffled me some.  I like how the 
Nixie tester/healer has the connections to hook up to MM to measure current and 
voltage.  To have this measured by the processor in the clock is neat idea.  I 
also like the idea of controllable current and voltage from software... That's 
true flexibility.

Re: [neonixie-l] Anode current and voltage measurement

2019-05-12 Thread David Forbes
You can measure cathode current much easier than anode current, and it's
the same thing. Tie all your cathode driver grounds together, and put a
small resistance between them and ground. Select the resistance so that it
has a bit less than one volt when operating.

[neonixie-l] Re: Anode current and voltage measurement

2019-05-12 Thread gregebert
Anode voltage is easy; just use a resistive divider to get the voltage 
within the range of your ADC, and be sure to put a filter cap (0.01uF 
should work) at the ADC input (most ADC inputs appear as a 
switched-capacitor).

Current is a different animal. The easiest way to dodge this is to use a 
current-limit circuit at each anode and you really dont need to measure it 
anymore.

Anode current can be measured at the cathode side by tying all of the 
cathode drivers together, then connecting to GND thru a sense-resistor. For 
example, if you use an HV5530 to drive your cathodes, connect all of the 
VSS pins together, then to GND thru a sense resistor. If you drive 3 tubes 
from single HV5530, your max current will be about 15mA. Next, select a 
sense-resistor that will give about 1V drop at 15mA; by ohms law this works 
to about 67 ohms. Be aware the sense-resistor will affect the 
signal-integrity into the HV5530, so be sure to use the recommended input 
levels (12V logic), and this will directly impact your low-level noise 
margin. But with a 1V drop, the overall impact to noise margin at 12V 
signal swing is negligible.

The other option is high-side current-monitoring. You could use a cheap 
analog or digital meter and put in-series with the anode supply. If you 
want to extract that info for you microcontroller, then your best option is 
to have an A/D converter on the high-side, and use opto-isolators on the 
serial interface to the ADC. There will be a fair amount of support 
circuitry for this, so be warned.

Seller must have had a change of heart after all the chatter circling the 
web on this topic.  He's now lowered them to a much more affordable $950.00

I guess now they're just RARE and not BEYOND Rare.

I would like to be able to measure the anode voltage and current on one of my 
clocks and have a permanent display of those values built in to it. I came 
across this reference design at TI 
(http://www.ti.com/tool/tida-00528?jktype=design#technicaldocuments) but was 
wondering if anyone can point me at other possible solutions?
