Re: [neonixie-l] Who simulates or protoypes their designs before doing a PCB ?
I am a chemical engineer and when I retired I was working on the safe
landfall of north sea oil and gas. I have little formal electronics
training and I'm mostly self taught That said
I do a mixed bag of experiments using dead insect on a copper sided
PCB, a plug in board, a literal breadboard (mostly for valves), strip
board when I want something semi-permanent or for a long running
experiment and simulations using LTSpice. I tend to do what I think is
best at the time for the tests I want to perform. I do enjoy building
things, this is the hobby after all.
My use of LTSpice is limited to analogue stuff and some power supply
simulations. I've not had too much success with designs that use
inductors in particular. But I spent some time simulating various CRT
deflection amplifier designs before moving to a PCB and I was not
disappointed by the results. I know I should simulate more before
heating up the soldering iron...
For PCB design I own an unlimited copy of Eagle 7.7.0 which was the last
version before they went subscription based. It is getting old now (like
me) and I have looked at some of the all-in-one design software but
Eagle does what I want (schematic to Gerbers), I know how to use it and
I have a large component library that I have developed myself. So I
don't feel a need to go anywhere else: I am unconvinced that the
facilities in any new software would be repaid the time I would spend
learning how to use it. But my prototype PCB designs often have
problems: they tend not to be "electrical" but "mechanical" in nature.
Components are too close or I goof with the silkscreen such as I label
things incorrectly - this is just incompetence I know.
Going back to the simulation question - I started with QUCS and then
moved to LTSpice - should I look to use another simulator? What should I
look at beyond LTSpice?
Keep in mind my limited knowledge of electronics and the need to
self-teach!

Just curious to know how many of you run logic and/or

Since I'm a longtime designer of IC's, I rely heavily on
simulations: ngspice for the analog sections, verilog for
the entire PCB (logic, FPGA if any, and analog). Once that
is done, I go straight to PCBs with no prototyping. So
far, I've only had 1 project that required any 'blue
wires' to fix a design error.

Re: [neonixie-l] Scope clock STM32
Hi Paul Your clock is lovely. Glad that I able to help in some way. I used (9 years ago!) DXF format for my graphics and now reading about SVG it looks to be a superb format for scope clock fonts and graphics. I look forward to seeing the evolution of your clock! Grahame On 26/02/2024 09:12, paulvr wrote: This is my first post in this forum and I would like to introduce you to my version of the scope clock. Mainly inspired by the work of David Forbes and Grahame Marsh. The work is not finished yet, but I have reached a milestone for myself in that all components are on one PCB and only one voltage source is required, nm. 12 volts DC. The high voltage is made using a standard Würth WE-flex transformer, plus and minus 250 Volt. The filament voltage is provided by a buck and forward converter and a standard Würth push-pull transformer (6.3 Volt to 600mA). The MCU is an STM32G491, mainly chosen because of the integrated 12-bit DACs. The image composition is completely DMA controlled and works independently of the CPU, which therefore has a lot of time for other tasks. The characters and graphic shapes are encoded as SVG path. An ESP32 has been added to achieve the correct time according to the NTP. Operation is entirely via a web server running on the ESP32. The software is not finished, and not all functions work (work in progress). The next step is to try out other CRT tubes and make a housing.

Re: [neonixie-l] Scope Clock with 3LO1i
Hi The DH3/91 is a nice tube. It has "automatic focus" so there is no external connection to the focus anode. To keep the pin count down to 8 it has asymmetrical Y deflection but it is an easy low voltage tube to use. I used one in this project http://www.sgitheach.org.uk/scope1.html Grahame On 02/12/2023 20:14, Max DN wrote: @ Anders Thanks for that. Yes, I'm sure you are right. At the moment I can only get it to work well with Brightness and Focus potentiometer in parallel (it's working ok, but I want to change that and have those potentiometers in series as per standard config). Picture attached (CRT came with a center point already a bit burnt, no biggy, it'll likely extinguish itself soon anyway!). I only have 500k and 1M POTs at the moment. I'm waiting for a 100k POT for the Brightness and from my calcs that should help given my power supply (+240V and -450V). I'll update you when I receive the parts and I'll post my solution for the resistor bleeder. @Grahame. I bought a DH3/91 - super cute CRT! I cannot wait to try it. Il giorno sabato 2 dicembre 2023 alle 12:46:52 UTC Anders Mikkelsen ha scritto: The current draw for CRTs is mainly between the cathode and A2/A4 (main accelerating anode). A majority of this current flows directly between the electrodes, while a small fraction is represented by the actual beam current hitting the phosphor screen. You need to ensure that the impedance driving these electrodes is low enough that the voltages don't move around a lot when adjusting the brightness grid bias, otherwise the focus, astigmatism and brightness controls will interact in ways that make it hard to control, and brightness modulation will also affect focus.

The book covers the fundamentals of how the tubes work, the history of the cathode ray tube development from 1603 (!) to about 1990 (including a contribution by Jean Picard would you believe), useage in radar, useage in oscilloscopes and more sections besides.

Re: [neonixie-l] Scope Clock with 3LO1i
Hi £55 is expensive - you should be able to get them for £30. Have you tied the deflection plates to A2 for testing purposes or left them floating? They should be tied to A2. Can you turn the brightness pot down to fully extinguish the dot? If not you need to be able to. Grahame On 25/11/2023 18:28, Max DN wrote: @Grahame Thanks for the suggestion.

[neonixie-l] David Forbes?
Hi all, Just reaching out to see if anyone has been in contact with David the past few months. I reached out to him mid-June of this year for a repair on my nixie round watch. He replied to my first email the next day with instructions to ship to him, so I did. Since then, I have attempted to follow up a number of times over email but have not received a reply yet. Wondering if he is alright at this point; hopefully just out of office but nothing serious? Either way, thought I'd reach out to the group at this point since I'm not having any luck making contact.

How much current are you using in a directly driven tube? I’ve had the same issue with the pins lighting up with as little as 1mA on the Z570M tubes.

I have a clock that has some glowing lead wires from the glass seal to where it connects to the individual cathodes. This doesn’t happen on every cathode in the tube. I know this can happen if too much current is applied but these tubes are running at the rated current or below when using PWM for dimming. So my question is; does anyone have an tricks to resolve this without just changing out the tube? Trying to avoid changing as these tubes (Z570M) are hardwired to the PCB.

Is it possible to use some OG-4 without the G3 input and corresponding cabling ? the speed is not critical and I would like to keep the classical orange glow instead of the argon.

[neonixie-l] Re: Repair of an original Jeff Thomas NixiSat...
Just a quick addition - the dead Xicon electrolytic had no visible signs of failure - no bulging or leakage at all. The DMMs, however good they are, were mostly useless in this case as they were simply confused by what was happening - no DMM or analog VM would have helped much - an analog VM would probably have been worse as it may have reacted as a true-RMS meter which would have hidden this issue completely. At least the DMMs went a bit bonkers, which made me think a bit! The 'scope is what nailed it; the gate on the FET was clear, as was the mad HT output line.

[neonixie-l] Repair of an original Jeff Thomas NixiSat...
So, I have had an original NixiSat from new, so a long time now - I detailed it's restoration to a more modern time source and working condition in these two threads: https://groups.google.com/g/neonixie-l/c/vcNOdSB3nYM/m/3AmeUTtCAQAJ ...and... https://groups.google.com/g/neonixie-l/c/evzX0noEGXg/m/JrVaZG3YFogJ However, a couple of days ago it had completely died; the PSU, a switched-mode 12V 2A wall-wart was fine, but the clock was completely dead. A quick check showed that the tiny 1.5A fuse had blown... and the IRF740AS FET was TOAST, almost literally. It had got so hot that it had burnt the PCB, (1cm charred circle) lifted the track and died to the extent that it no longer identifies as any sort of semiconductor... it's shuffled of this mortal coil and gone to join the heavenly choir invisibule... . Interesting smell, well known to EEs (no, not pizza, burning FR4). I replaced the fuse, did some clean-up of the crispiest bits, removed the CPU, dead FET , the tubes (position recorded for each tube as it was wrapped and stored) and HV drivers and did some voltage checks. The MAX771 was running and the 5V rail was fine... the HV drivers and CPU were looking good. So I replaced the FET with a more modern FDB14N30 which is also in a TO-263 (D2PAK) and is just generally a better FET (and I had some) - specifically lower Qg & RDSon; similar VGS(th). Tracks repaired just for the FET drain with 28G TCW. Using a good lab PSU (Tektronix PS2521G), 'scope (Tektronix 2465A) and DMMs (Agilient U1272A & U1253B) plus an Aglilent FLIR, I started looking for trouble... it arrived quickly. With 12V in, the current went right up to 260mA and the FET temperature started climbing rapidly - at 70C I cut the power. The HT rail was not easily readable and was the first indicator of what might be happening. The FET gate was looking fine with variable width pulses at about 45kHz but much more "mark" than "space" - not what was expected for an unloaded HT SMPS boost controller - it should have settled really quickly into more "space" than "mark"... Looking at the HT rail using the 'scope was revealing - it was all over the shop, from about 120V up to 290V - sharp rise time and then decay until the next hit from the inductor... Just for sanity, I checked the feedback resistors - 1M5 and 12K7 - they were fine, but obviously what was happening was that the wild swings were driving the MAX771 insane, that was keeping the FET mostly on and that in turn was connecting the FET between 12V and GND with about 0R25 or series resistance (the current sense resistors, 0R125 and the inductor 100uH and 0R11) plus the RDSon of the FET (which is about 0R290). What on earth would cause this? It's obvious if you think about it :) The boost converter output tank capacitor should be 4u7F @ 400V. I removed it and checked - it came in at 5p5F ! Another dead component. For reference, it was an Xicon. Without a tank, the output will do exactly as I observed and the FET will cook. Lucky that other stuff like the HV drivers and the MAX771 didn't get damaged too... Replacement cap - I had a nice, good quality Nichcon 10uF @ 300V with the same pin spacing, so used that. All done. Without the tubes, the NixiSat idles now at about 25mA with the FET stone cold and the gate staying at 0V as the tank was a nice, steady, 182V. Replaced each tube in original position. All good. Clock fixed for almost nothing, but an interesting lesson for those who haven't fiddled with these sorts of supplies...

Re: [neonixie-l] Original Tube Prices
Many years ago I bought some NOS B7971s - they came in expanded polystyrene trays moulded to half a tube lying down, 16 at a time, at about USD 10 each. Whilst they could have been pulls, there was very little ghosting so I suspect they were genuinely NOS or at least very close to being NOS. Most of my current stock was from US Mint at between USD 15 - 20 and we all know the pain that was... It's worth remembering that these are rated for a minimum of 200,000 hours running which equates to about 8330 days or nearly 23 years of continuous use. Also, there is no real definition of nixie lifespan, i.e. what constitutes end-of-life. Weston suggested EOL when 50% of the display was obscured, but there is nothing standardised. Personally, I've never had a B7971 fail or even look that used, and there are some clocks/FLWs around here that have been running continuously for 20 years or so.

Re: [neonixie-l] ScopeClock with teensy4.0

Hi Is that image of the face - showing the image offset twice in the X direction only - what you see with your eyes or is it a camera artefact? If it is real, what happens when you rotate the tube? It is interesting that it seems to occur in the X direction only. If you feed the X and Y data from the DACs into a scope in XY mode do you see a good image or this offset one.

I suggest leaving each value for about 10usec to allow more than enough time for the DAC and amplifiers to settle. Which DAC are you using ? My only experience is with 8-bit parallel-input DACs, and I had no problems with it (ADCs, on the other hand, are a different story). If you see erratic behavior, post the findings and we can figure out next steps. If the DAC is operating correctly, then my first suspect is the range/offset of your DAC. You might not be able to drive it rail-to-rail due to the design of the level-shifters/deflection amps. In that case, try to narrow-down the range where the DAC is driving the CRT as-expected.

Re: [neonixie-l] Date codes on ETL GR10x tubes...
Thanks for asking, but I really don't know yet. There's a HUGE number of tubes to go through (many 1000s). A few of the exotica have been sold to other collectors, but there is a set of 6 matched GR114/CD47s (will sell only as a set) amongst the stuff in the store, plus many other rare tubes. I'll start doing auctions in a few months and will provide early warning here. Some of the stuff is extremely rare, including F9020, NEO-5000M, NEO-8000, loads of NIMOs, Pandicons, Pixies, Panaplex, Alphanumeric tubes etc. On Tuesday, 30 May 2023 at 17:55:20 UTC+1 Robert wrote: > Hi > > What would the cost be per tube, used or NIB? > > Thanks > Rob > > On 30 May 2023, at 17:40, 'Nick' via neonixie-l > wrote: > > So here's the thing: I'm rationalising my rather large nixie collection > over the next few months I don't need lots of every nixie. > > > I'm starting with a stash of ETL GR10Gs in varying condition - one has a > broken 7 internally, 3 others are "dark" to the point of ... just > useable... another 10 are in "used but good to OK condition" and the rest > are NIB. > > They're a strange, early, tube, needing a Va of 250VDC and an Ra of only > 10K for most digits, but 18K2 for the "1" and 14K7 for the "7", i.e. the 1 > & 7 also have cathode resistors...

So here's the thing: I'm rationalising my rather large nixie collection over the next few months I don't need lots of every nixie.

They're a strange, early, tube, needing a Va of 250VDC and an Ra of only 10K for most digits, but 18K2 for the "1" and 14K7 for the "7", i.e. the 1 & 7 also have cathode resistors... They have no Hg doping, so the life of the tube under controlled circumstances is only 5,000 hours... Early stuff. But they are a BEAUTIFUL tube... I mean, REALLY BEAUTIFUL (IMHO)...

Re: [neonixie-l] Re: Neonixie Spam Messages
Hi Just the one pending this morning.. No overly eager moderator - my memory is that we have deleted 4 posts in the last couple of years - two from a Russian tube seller seeking to bypass sanctions and two from someone advertising gold. As Nick said, there doesn't appear to be any moderator controls on spam delete/pending so we are just going to have to live with this problem for now. I appears there are two levels of control by google - one is they delete the message outright - the second is it goes into a pending folder for the moderators to approve. I will watch the post contents more closely and see if there is a reason why posts are being moved to pending.

Re: [neonixie-l] Is there a cheaper alternative to the IN-18 at that size?
Hi everyone As Nick said, Google sometimes puts messages into a "Pending" folder requiring moderator approval. I just approved 3 pending messages including the one from you, Yohan. This is a Google thing and we just have to live with it.

Re: [neonixie-l] ScopeClock and GPS
Hi Michael, I'm also using the BU-353S4 on mine and it's working fine too. I believe that the software that David ships with the clock is looking for a 4800 baud rate with one NEMA message string update per second. Anything else is not going to play well.

The final results is below: it uses 20 IN-13 tubes, 10 for each channel. The choice of frequencies matches a home-made 10 octave equaliser you can see below.It is working fine, though some channels need some additional fine tuning! It is fully analog.

Re: [neonixie-l] Re: just wondering what these tubes G10/241E go for
I have two G10/241E and both are dead unfortunately but physically intact. Grahame On 23/12/2022 09:14, Jon wrote: Primarily a tube collector item I'd suggest. They're fiddly to drive and the display is much less visually striking than other dekatron types, so there's not a lot one can do with them in the direction of a clock or similar. And then there's the question of condition - many G10/241E don't work now, even if they're apparently NIB (there's a 'death in storage' problem that afflicts many high speed dekatron types including this one). And the metal base shell is prone to cracking and falling off the tube which is cosmetically unattractive. So a scraggy tube without proof of function is pretty worthless IMHO. At the other end, a tested mint tube in the original box is probably a few tens of dollars, depending on how interested the small pool of likely buyers is at that moment. If you've got one of these you might want to sell, you're welcome to PM me some pictures and I'll try to give some more specific input - I've done quite a bit of historical research on these tubes. They're actually a really early solution to the counting tube problem, but one which largely lost out in commercial use to the more elegant and flexible Ericsson designs. While we're on the subject of STC counting tubes, does anyone have a working G10/240E (note different number) that they'd be interested to sell? PM me if so! Cheers, Jon.

[neonixie-l] Querry on Burroughs symbol tubes
Dears , I have received a couple of Burroughs symbol tubes and I have some trouble with identifying some of them , if I could say . The issue is with 2 tubes that share the same symbols with one marked as B-5994_ 4 (_ = empty space and the last 4 is a little bigger than the rest of characters ): This tube displays : F , Omega (small size ) , Hz , A , V , S (small size ) The other 2 tubes share the same symbols with the difference that the Omega and S are with the same size as the other characters ; unfortunately the marking are erased , but I could " see "the last numbers on one of them as 952 or 962 , Could that be the B-59952 as listed on AJ Franzman list ? PS , maybe some one has a more comprehensive list of tubes made by Burroughs and National that is willing to share .

Hi The moderators have had a discussion about this and we've decided to ask the poster not to use this forum to circumvent any sanctions in place as we are a strictly non-political group. They may well advertise elsewhere, but not here. These issues are complex - there are millions decent & honest Russians - this is a war of their government, not the masses - however as a group we cannot pick & choose and at this time we certainly cannot advocate round-about routes for paying for Russian goods.

Re: [neonixie-l] IV-17 Explorer Kits & ZM1350 Smartsocket Boards — Both With Tubes
This seller is some kind of estate liquidator I'm convinced of that. Some of the clocks he sold could be traced by serial numbers and the original buyer has since passed away. Again, this is my speculation based on the deceased and where this seller is located, both in Northern New Jersey, Metro NY area. As far as the sex toys, who knows maybe they bought out one of those seedy places in Times Square.

[neonixie-l] From the Moderators...
Occasionally we remind members about what the group is about and what it isn't to encourage on-topic, healthy & constructive discussion. There is quiet a lot here so our apologies for the long email... _Underlying Google Group Rules_ All Google Groups must adhere to rules of basic decency. The Google Content Policy is here https://support.google.com/groups/answer/4561696?hl=en <https://support.google.com/groups/answer/4561696?hl=en> You'll find nothing in there that will surprise you. _The language of the Group is English_ Please realise that many members' mother language is not English. If you have problems phrasing what you want, then try and no doubt you will get help. _What is on-topic and what isn't?_ Although the noble gas "neon" and the trade name "nixie" are in the group name, we are not just limited to devices that use neon or are nixies. Other gases, other types of gas discharge tube, vacuum devices, incandescent filaments, semiconductors and mechanical devices can all be on-topic (probably missed a technology or two here). What is on-topic tends to revolve around (but is not entirely limited to) clocks, counters, computing, display devices and examples of their use in DIY or professional equipment. Construction techniques and materials are all very useful to share here as well. We are trying to be intentionally wide and vague. A question about the best feed for your tomatoes or hum in your audio amplifier are likely to be better posted elsewhere! But posts about removing scratches from/cleaning acrylic, or about DIY PCB making are likely to be on-topic. Posting off-topic is not entirely discouraged. If you have something that you want to share then start the subject of the email with "Off Topic:" or just "OT:" please. _What about advertising?_ A modest amount of on-topic advertising by established group members is allowed. In fact we would encourage members to sell items to other members ahead of using a market place website, e.g. eBay, "keeping things in the family" as it were. Off-topic advertising (see tomato feed above), bulk or repeated advertising will be removed. Posting links to on-topic items for sale, whether you have any affiliation to the seller or not, are acceptable. Personal comments on a seller's performance must be considered carefully. You must comply with the Google Content Policy as a minimum, it is one thing to warn or advise but another to rant about the one bad experience that you have had. _Politics_ The group is apolitical meaning having no interest or involvement in political affairs, world or local. _When things go wrong_ Occasionally, members have difficulty in posting or receiving posts from the group. Google have some blurb on the topic here: https://support.google.com/groups/answer/70498 <https://support.google.com/groups/answer/70498> If you want to change what you receive, then you should change your membership settings. The choices of what you receive are * Each email - Each message is delivered as it's posted * Digest - Messages are sent in bundles of 25 * Abridge - Abridged messages are sent in bundles of up to 150, at least daily * None - no emails sent If you are failing to receive emails then 99% of the time it will be settings on your device that are blocking the messages. Google Groups now seems to be very stable and problems with it are now rare. Some email services are known to block Google Groups. There are limitations on how frequently you can post, however Google don't actually seem to say what the limits are anywhere. There are limitations on the size of attachments. When you go looking, various numbers are offered from a few MB up to 25MB. There may be other limitations set by your email software or settings on your device that prevent posting attachments. When a member does have problems posting we now rarely find it is Google Groups. See also https://support.google.com/groups/answer/70498#zippy=%2Ccant-post-messages <https://support.google.com/groups/answer/70498#zippy=%2Ccant-post-messages> Moderation Member's posting rights are normally set to fully allowed. The moderators can set a member's rights to "not allowed" and "moderated", this happens oh-so rarely. The moderators can also ban members from the group for infringement of these rules. Our banned list is currently empty, but that can change at any time. Moderators can also selectively delete inappropriate messages or conversations. It's extremely rare that we take action, however in all circumstances, the moderators' decision is final. Hopefully you have found this summary useful (and on-topic).

Re: [neonixie-l] IV-17 Explorer Kits & ZM1350 Smartsocket Boards — Both With Tubes
That eBayer has been selling a lot of Nixie related clocks, tubes, etc along with sex toys. From what I can tell he must be a liquidator and I presume bought out a Nixie collection from someone who either passed away or decided to get out of the hobby.

Re: [neonixie-l] Jeff's Nixie watch parts layout or schematic?
Hi Nick, I appreciate you sharing this BOM, but it's for the Commemorative clock which is the one that replaced the one I have. Mine is his first piece that used a modified Mike Harrison PCB and work on mains power not a 12V power supply.

Re: [neonixie-l] Jeff's Nixie watch parts layout or schematic?
Hi Nick, I appreciate the BOM but the clock I have is the first one. The Commemorative one that you were kind enough to share is for was for the one that replaced the one I have with the modified Mike Harrison board and ribbon cable in it.
