Yes, the tube timer was a feature since day 1. I bricked the original CPU 
on my oldest clock (botched update on my part) and don't know its 
total hours. The CPU I replaced it with (0 hours when installed) is 
reporting 56,200 hours (checked just now). This is with no display blanking 
at night, just some dimming. The MOD-SIX is a direct drive design using PWM 
for dimming, BTW.

The MOD-SIX page says the new version has an optional PIR sensor, so it 
should be possible to blank the display when nobody is around. The current 
firmware already has 2 programmable display on / off settings. The manual 
has examples of using them for both an office and a home schedule.

I've never had a tube fail. AFAIK, no-one else has either (purists may 
cringe at my manual's "carefully bend the pins with pliers if necessary", 
but it works).

My experience with these tubes is that they obviously have excellent shelf

Agreed. The youngest of these tubes is probably close to 50 years old at 
this point, and I've never seen a real "NOS" one - the ones on the 
Lectrascan display boards were obviously from units that were replaced by 
newer types of display, but the tubes I've seen represented as "NOS in 
original foam trays" appear to be preventative pulls from displays, given 
the mismatched date codes and overall condition.

There have been a number of revisions to the tube design (I think the ones 
with the "antenna" wire are the oldest, used to position the assembly 
inside the envelope), but unlike other tubes of the same vintage, the older 
revsions don't seem to be less reliable.

I have a number of bad tubes, but they were all received that way.

Terry - I don't know if your earlier MOD-SIX clocks had tube hour registers, 
but my curiosity is how many hours do you have on your B7971 tubes on your 
clocks?  Have you had any failures?  
My experience with these tubes is that they obviously have excellent shelf 
life, good seals and seem to be easily capable of 100,000 hours in actual use.  
It would be nice to know of some actual elapsed time readings in nominal 
circuits. 
PS:  agree that the latest MOD-SIX looks great!

I have not received any response.  Has anyone been in contact with Chris in

You shouldn’t have received a faceplate that was scratched. I would have 
returned that one (as I have done before). As long as you use a clean lint free 
cloth and the correct cleaner it’s pretty easy to clean acrylic. Fire polishing 
can work, but best if you practice a bit first as has already been mentioned.

Have you tried fire polishing it?   It worked for me.  For more info, just

Are ya'll talking about re-releasing this clock? If so, could you do a 
glass version instead of plexi glass? I would be interested in buying 
another one if so.

Thanks,

I'm guessing they're referring to a "trace antenna", where a PCB trace is used 
as an antenna (do an image search on "bluetooth module" if you're unsure what 
I'm referring to, that zigzag gold trace is the Bluetooth antenna).  I doubt a 
u.FL connector would qualify.

Re: [neonixie-l] PCBWay

[Luka C]

I will be placing a PCB order soon so I have checked Elecrow that was 
mentioned in this topic. They have a pdf with details on SMD stencil 
production ( 
https://www.elecrow.com/download/Readme%20before%20ordering%20stencil.pdf ) 
. In the document they state that they will use the "paste" layer to 
manufacture the stencil except in case there is an "obvious RF antenna". 
Considering my PCB contains an UFL antenna connector, what would this mean? 
Perhaps someone knows?

Re: [neonixie-l] Re: Nixies on AliX

[HuggerMugger]

I suspected something like that as some items “looked to be good” to come from 
the AliX vendors. 


Accidently ran into someone out there selling a kit for the Arduino-run Menta 
synth (in an Altoids tin can). Thought just Adafruit sold these

Please don't fall for the fake one, this seller use my pictures but copy my 
NCH6100HV power supply with low quality components and wrong parameter. 
My NCH6100HV use high quality components(TDK inductor. nichicon high voltage 
capacitor... ) with gold-plated PCB board, customized connectors with different 
color, fake one use only gray one...
They print my brand logo and my URL on the board, but they never know what's 
this module will be used.


Fake one here:

  Suffering for some jetlag and just looking up some stuff on eBay and 
  AlrExtress I notice that AliX has started selling Nixies. Not sure what the 
  quality/price are in comparison. Many claim that ICs sold on both places may 
  be pulled,fake or watever. 

  I list, just some of the things I find starting with what intrigued me most, 
  a DC/DC-converter:

  Russian IN-14 tubes (there are surely lot more vendors):

  h?!) 

  A few clocks:

  Been buying stuff from AliX för a few years and have to admit that just a 
  few cheap products have ended up in the bin. Still have some ICs to check 
  out - just got a packet of ICM7217.

  PS. Just got a pair of VFD clock displays from eBay:

[neonixie-l] Re: Clock Three Jr. - What Amp for AC adapter?

['Dave' via neonixie-l]

If anyone is interested in making one of these, 
I did a run of the PCBs for my own use have have some extras that I would 
sell.
Just hit the 'reply privately' option to me if interested.
cheers,
david

[neonixie-l] Re: Microcontroller driven boost converter

[Tomasz Kowalczyk]

Thanks! I looked into the code and it generally looks similar to my 
pseudo-PI approach (preloading PWM to some value and then simply ++ or -- 
if output is too high or too low). I had troubles with slow response, but I 
think that it was because how analogRead is handled on STM32 hacked to work 
with Arduino. Also I wasn't calculating new PWM in main loop, but in an 
interrupt - maybe it was too slow?
I'll copy and paste his code and test it with an oscilloscope, when I find 
my real Arduino...
