Yep. CUPL and ABEL (from Data I/O).

 If so, have you tried to reprogram the Teensy or even erase it to set  
 it to its original setup condition?

 Martin, that's what I am thinking... however I don't think it's the

 few 
 components only: 2 potentiometers for centerting X and Y, their two

 capacitors, the DAC and its 1 bypass capacitors, the +3.3V Linear

Many of his other tubes ship for $7.90, so we can assume this is a typo.

[neonixie-l] Nixie shirts!

[Terry S]

I worked a little with the vendor on these, blame me if you don't like the 
image. I did choose that tube. But the vendor may have some flexibility, 
seems very accommodating.  I'm ordering mine tonight.
 
Lots of other cool images as well.

[Terry S]

I agree, don't change a wire! It's a piece of history as-is. Fix any 
defects and let it live as a tribute to the original designer. Who are you 
(or any of us) to second guess the designer? Could you update it with an 
Arduino and make it do back flips?  Yes of course But should you? No.

Yes that's correct. There's a PIC on the clock board that drives the 
pushbutton input. The clock board gets some fairly simple modifications:

Re: [neonixie-l] Re: It lives!

[Terry S]

It's an entirely different movement. To work with Jeff's code and hardware, 
you must find the old movement with a large red button. There are old 
movements with a blue button; best I can tell, (disclaimer: I have not 
taken one apart) these will not work either. They use a different push 
button sequence to sync the hands to the current time.

He did indeed, Nick. I feel fortunate to own a couple of them.
Unfortunately the WWVB clock movement he used on this device has become 
unobtanium. I have one stashed away, bought at a local thrift store. if

Greg, I'm in western Wisconsin, so not terribly far. I'm probably only 
seeing a 5 msec delay, I can live with that.

 Maybe for an alarm input? Would need a switch for AM/PM.

 What else can it be used for ??

 I don't need all the quantity I have.. so if anyone wants some PM me.

 Thanks!

[neonixie-l] Re: Jeff Thomas WWVB clock modification

[Terry S]

And another option might be to just have the Arduino emulate the WWVB 
receiver function. I'd have to supply it 5V instead of 1.5V. Just 
spitballin'.

[neonixie-l] Jeff Thomas WWVB clock modification

[Terry S]

Guys, thinking about modifying my big beautiful Jeff Thomas clock. The 
original Atomix clock movements are hard to find, and in my area WWVB 
reception is very spotty (and I have a metal roof).

Here is the clock schematic:
http://www.nixie.dk/~jthomas/example.pdf

I think with just a little rework, I could modify the design to talk to an 
Arduino. I'd have all the counters reset to zero from the Arduino, and then 
have the Arduino clock the counters  until they catch up to the current 
time as grabbed from the web via WIFI. I can handle the hardware design and 
the rudimentary code that would be required to reset and clock the 
counters, but I'm definitely going to need help with the WIFI and time 
retrieval portion.

Anyone willing to lend a hand from that standpoint? My code skills are, as 
I implied, crude at best. I would need advice on selecting a WIFI shield as 
well. 

Open to other ideas too.

Terry

[neonixie-l] Re: My in-14 tube died strangely.....

[Terry S]

Because nail polish is a thin porous coating with no strength per se. Would 
you trust it to seal a leak in a tire or a crack in a drinking glass?

If a tube is going to outgas around the glass/pin interface, no coating or 
other treatment is going to prevent that leakage. The seal is either good 
for the life of the tube, or if it's not, it's either a faulty seal from 
the factory or it has been compromised by mechanical or thermal damage.

 It's CCCP IN-14, no over current or voltage.

 You can see, even the anode grid have some discoloration. 
 It's not normal in cathode poisoning, right?

 And it's working video:

Re: [neonixie-l] Anyone purchased one of these clocks?

[Terry S]

Dan, I need to disagree with you on several counts. It's an .062 board and 
the vias are small. Plenty of space between D+ & D- and the ground plane, 
at least 10 mils. It's likely just a 2 layer board, but as someone who 
spent 25 years of my career designing PCBs, I find very little fault with 
this layout. 

Traces are 6 to 8 mils except for power distribution & HV. The layout is 
fairly clean and well thought out. The silkscreen is very good and I found 
no acid traps. Trace to trace clearance looks a bit small on signal lines 
but it's nothing that can't be manufactured reliably today. The simple 
architecture is a bonus in my opinion. 

He used copper pours a bit inconsistently but it's not a crime on this tiny 
board. 

Overall it's a competent design and quite a bargain. If the code was open 
source I'd certainly change a few things with regard to setting time and 
button operation, cathode poising routine, etc. But for this price it's a 
great little clock and a nice gift item.

Yes setting the time and backlight is rather twisted.

Re: [neonixie-l] Scope Clock - HF transformer dirving circuit and PCB layout evaluation

[Terry S]

I've designed hundreds of boards and never had a problem with silkscreen or 
soldermask related to conductivity. I seriously doubt any reputable PCB 
manufacturer would use a mask or ink that would be the least bit conductive.

I will say most of my designs were sub 50 volts.

I never specified an ink manufacturer or specific brand, but I specified 
plenty of different specific solder masks. Ink was always left up to the 
supplier.

[neonixie-l] WWVB clock

[Terry S]

As I mentioned in a previous thread -- my Jeff Thomas WWVB clock is broken. 
A couple members here offered help, which I appreciate. But as novel and 
cool as the WWVB clock approach is, it's a bit of a dated design and I'm 
investigating doing something more "modern" with the big Z568M tubes.

For those that may not know, the clock uses a modified "atomic" clock 
module from an ordinary WWVB sync'd wall clock. An 8 pin PIC set up as a 
timer manipulates the lone input on the clock board as if a user was 
pressing the button, setting the initial time and then allowing the WWVB 
receiver to speed up or slow down the conventional CMOS counters on the 
clock board to sync with WWVB time. It was truly an ingenious approach to 
have precise timekeeping back in the day.  (Hours still had to be set 
manually by the user, using a magnet and reed switch.)

With the advent of easy WIFI this approach is dated, the clock modules are 
difficult to find, and there is some tedious clock board rework to do, 
which I admit was easier to do when I had the right tools and magnification 
at my disposal. Problem I need to solve.

S.. I'm seeking out an open source design I can use/adapt for my 
big tubes. I'd like to lay out the boards myself so I can match the current 
footprint and use my existing enclosure. I'm not hung up on the whole "not 
invented here" syndrome -- I'm happy to use something well tested.

Arduino based would be ideal, but I can work with most anything. Retired 
now so looking to learn new tools.

Any suggestions?

Terry

Did a lot of that on failed electronic modules in my last job. Also 
scanning electron microscope analysis. Very cool imaging techniques.

Re: [neonixie-l] nixiechron issue (was Nixiechrom woes)

[Terry S]

Thanks for the ideas. It is working right now -- although I believe that 
getting to output string right would be better.

I do have Arduinos around and I could explore that path.

I have not had any luck getting my WWVB clock working yet. and that one 
has the big Z568M tubes.

[neonixie-l] Re: Nixichron woes

[Terry S]

The new GPS puck started working -- keeping both time and coordinates fine 
now. Has a lock at least 1/2 the time -- which is fine in my installation.

The WWVB clock is still not working. I may need a new receiver -- which is 
super hard to find now. It uses a circuit board out of an old "atomic" 
clock movement, modified. 

I could re-use the huge tubes in a new clock, but I like my enclosure and 
would not want to rebuild that.

[neonixie-l] Nixichron woes

[Terry S]

 My Jeff Thomas Nixichron has been misbehaving.

It's worked flawlessly for years. Lately (4 mo?) it's had a hard time 
keeping a GPS lock, so much so that the GPS coordinates would be wrong when 
displayed. Sometimes just a little, sometimes a lot. Then it would get a 
lock and seem to work fine for a while. It got progressively worse.

More recently even the time has been wrong, and the colon neon would never 
show a GPS lock.

All this led me to believe that the GPS puck was failing (I was on my 2nd 
puck, a GlobalSat BR355S4). So I ordered another and installed it today. 
Still no joy. It's just counting the minutes and not getting a lock.

Coincidentally, my Jeff Thomas WWVB nixie clock is also unable to get a 
WWVB time sync as of late. 

I need to fix both of these wonderful devices. Any input? 

I'd like to get the Nixichron converted to NWTS -- understanding that I'd 
lose the GPS coordinate display. I know some members here can help me with 
that and I imagine it's time to make that change. I'm basically clueless as 
to what's involved.

[neonixie-l] GPS receiver for Niichron

[Terry S]

I think the GPS receiver for my Nixichron is dying -- again. Last time I 
ordered a G-Star IV with a PS2 connector off ebay. Can't find one now. I 
seem to recall it was only around $25 bucks at the time.

What the heck is the failure mode for these receivers? I'm on my 3rd unit. 
They seem to degrade, not fail abruptly.

I used to have a piece of software that would run on my laptop and talk to 
the receiver. That's gone as is the PS2 and any other serial ports on the 
laptop of course.

I suppose now would be the ideal opportunity to sync it from the web so 
if someone can explain that to me and sell me the required stuff, I'd 
appreciate  the help.

Sorry -- the tube is a GS10C/S.

[neonixie-l] GC10/4B darkening

[Terry S]

I have a decatron clock I bought from a member here -- very neat piece that 
emulates an analog clock on the decatron face. I used a roll-top teak 
floppy holder for the clock case and it's a thing of beauty.

The clock and the GC10/4B ran for years, no hiccups, but in the last 6 
months the tube became almost non-viewable. The face has silvered or 
darkened. 

I can still see the glow from the side of the tube just fine.

I don't imagine there is any correcting the darkening.

Anyone have a nice GC10/4B lurking in their stash for a reasonable price?

Terry

Glad to see you are still with us.

 Tristan -

 Thanks for those hints.  the BLNK signal is pulsing at 60hz, and I 
 swapped Q13 without any change.  I also socketed U17 (6N137) while waiting 
 for a replacement to arrive.  Removing U17 from the circuit leaves the 
 display unchanged, so it does appear that the blanking circuit is the 
 culprit.

 I'll swap U17 once it arrives - and if that doesn't fix things start 
 shotgunning the passives.  

 Thanks again for the guidance, very appreciated!

Well it's clearly a dual preset controller :-)

[neonixie-l] Re: Jeff Thomas Nixie - New Site, B7971 FLW Nixie Kits, Tubes for Sale

[Terry S]

Christian -- thank you so much for preserving your dad's legacy.  Another 
member here also archived the original site and we've all benefited from 
that and now from your site.

I worked on a couple items with your dad and he generously gifted me a WWVB 
clock kit (so at least 2 exist!) as well as a Nixichron. Both are still 
running today, many years later.

Do you still have any of your father's Atwater Kent radio collection? I 
know he sold some of it off. Amazing collection.

Indeed. I believe I read somewhere on the interwebs that this clock is 
circa 1970.

[neonixie-l] Data Time nixie clock

[Terry S]

I've been watching these for years on ebay. Finally snagged one last night 
-- I hope I didn't beat out one of you with my last second bid.

https://www.ebay.com/itm/294351896097

This clock has always fascinated me. I believe it uses a mechanical clock 
movement -- decidedly low tech -- gears driving switches lighting nixie 
cathodes. An additional rotary switch to select the world time zones.

I'll add pictures once I receive it. I understand the mechanism is a 
mechanical wonder.

[neonixie-l] Nixies in a new car!

[Terry S]

Neighbor was showing off his new KIA Telluride last weekend, it has a 
massive center console infotainment touch screen. Very nice vehicle.

He turned on the radio and the station display was a very realistic 
depiction of nixie tubes! 

He didn't know what they were called, but he had seen them in my house on 
one of my several clocks.

Next opportunity I will grab a picture.

Guys, I also need help with this, as I have a Nixichron and I'm moving to a

large overhangs!)

Can someone help me out with an explanation of what I need to do? Rather 
purchase a solution than home brew.

Thanks, Terry

[neonixie-l] Interesting Nixie counter at auction

[Terry S]

https://www.ebay.com/itm/MSI-Nixie-Tube-Counter/174617954314?hash=item28a80a880a:g:AHEAAOSwmm1f-c7t

As a former career PCB designer -- I'm admiring the hand taped-out boards 
in this counter. They look amazing, so consistent and artful. I can tell 
they all bear the same signature, the same designer. Beautiful designs.

I hope someone here grabs this. Neat piece.

Michail, the files you sent me were not for the FLW clock. They were for 
another VFD clock.

I'm hoping Pete will still send the correct files.

[neonixie-l] Re: Marine clock

[Terry S]

That's why I was leaning towards numitrons. Pretty robust. It's a pontoon 
so I'm really not too worried about mechanical shock. However I also have 
some small HP LED displays that would look great.

I've identified a couple of gauge housings, but I'm having trouble finding 
the drawings/dimensions for them. I've picked ones that match the existing 
gauges in my boat.

Once I have one in hand, I'll take the next steps towards the actual clock 
design. Considering a GPS disciplined design.

I have one, I bought it for testing neon sign tubes. I leave it in my car

[neonixie-l] 4/6 digit clock

[Terry S]

Thinking about a new clock for the bedroom, I have IN-12s to use up. I'd 
like a design that functions as a 6 digit clock during the daytime or when 
the room is lit but blanks out the seconds digits during the night or 
when the room is dark. Also dims the remaining digits in the dark of course.

I also have IN-18s to use but I do want a smaller clock for the nightstand.

This seems like a reasonable design goal. Has anyone done this or something 
similar? What was your approach?

[neonixie-l] Blue Y1938 tubes

[Terry S]

Today I scrapped out a GE clock radio and salvaged the (4) Y1938 tubes. 
These are somewhat uncommon blue coated 7 segment VFD tubes similar to (I 
believe) DT1704s.

I tested each tube in my own clock, they all work. They are not "new tube" 
bright, but they all work. One tube has a small scrape in the coating but 
on the side, not the front.

Up for grabs, make an offer commensurate with what they are, and their used 
condition.

[Terry S]

My guess would be ENIG like on a PCB. Electroless Nickel Immersion Gold. 
The data sheet or the vendor's website would tell you the exact finish.

The far right column is part of the matrix as you would expect. It's the 
column adjacent that seems unusual.  I guess if the decoding is there for 
it, you could illuminate a + sign with that column.
