[neonixie-l] Re: red filter on tubes
FEV is based on coloured shellac in an hydrocarbon-based (alcohol) solvent - it does not require baking, just dries in air as the solvent evaporates - it's like traditional French Polish.

[neonixie-l] Re: Frank Buchwald's Nixie Machine
Its a shame that Z568x have become so expensive - I'm not convinced that they are actually that rare - there must be 1000s in the old Eastern Europe - like diamonds (which aren't rare at all), by dripfeeding the market, the price is inflated. Supply & demand... I bought my cache many years ago when they were 35 euros each - the price now is simply silly - not bought one for over 10 years now.

[neonixie-l] Re: Gas pressure in nixies...
That's really useful information -thanks! Do you "bombard" or otherwise clense the tube during evacuation prior to backfilling? I'm thinking of the nixies I want to refill - when the tubulation broke, air and general rubbish will have been sucked in and I'm not sure how to get rid of that. With neon tubes, you use a process called bombardment that hugely overdrives the tube using upto 15,000 volts and maybe 300mA to cook the tube up to se eral 100 degrees C - this process also activates (converts) the special coating on the cathodes lowering the work function and making the tubes more reliable -you have the vacuum pumps running whilst this is going on and that sucks all the rubbish and moisture etc. thats been burnt off out of the tube.

What gas pressure is there in nixies? I suspect just a few Torr or approx 1 kPa? And how much Hg was put in each tube - looking at Ar or Ar/He-filled display tubes which use up to 200mg of Hg (but can be a metre or more long), a pill of about 1 to 5 mg might be needed.

Also been doing a bit with RPis - just used two B+ versions to turn dumb 40"+ flat screens into smart wallboard monitors - interrogates max pixel depth & resolution over HDMI, sets the screen to max resolution with no borders, sets up an equivalent frame buffer on the Pi and then runs the matchbox window manager & chromium in app mode to display the pages full screen with no boarders or titles, mouse etc. If the TV is turned off or the HDMI unplugged, the Pi goes through the query & set cycle again so you can swap screens etc. and it'll always be full colour depth and full screen size.

[neonixie-l] Re: Nixie Clock Cool Project- a few questions
OK, some basic on SMPS design: 1. All SMPS designs have losses, some more than others. This results is heat being generated and devices get warm. The two devices that may exhibit this are the switch FET and inductor. In a good SMPS, the FET will remain cool-ish and so will the inductor. This design uses an old-ish chip that is not very efficient, but should be good enough. 2. Do you actually have a problem? How do you know? In the light of point 1. above, your FET will get warm, but how hot is yours? Quantify the issue - is the FET at 30C? 40C? 50C? 3. If the FET is actually getting very hot, i.e. too hot to touch, it may be due to internal losses (RDSon for that FET is quite high, so it may get quite warm) or it may be a sub-spec FET 4. Sometimes in SMPS designs, you can get RF oscillation - it may be that for some reason that is happening here... ...however the designer of that clock is a knowledgeable guy who has build a load of clocks- first thing should be to ask him. Have you done that? When tacking an issue like this, firstly establish whether you actually DO have a issue - speak to the guy that designed & built it. Remember that SMPSs are fickle beasts and sometimes misbehave and need care & feeding- judging by your apparent level of knowledge, this is not something you should do yourself - speak to the designer, Secondly, forget about drilling holes and fans etc. for now - absolutely NO WAY should that be necessary - this is a proven design by a good supplier - if you feel its not right, SPEAK TO HIM ! Thirdly. a little knowledge is a dangerous thing - forget the random stuff about "electro-migration" - it simply is complete rubbish in this context. To quote from a recent Intel research paper: "Electromigration (EM) remains a serious problem for the reliability of VLSI integrated circuits, and will become an even more serious issue as future IC's employ linewidths below 0.2 micron" Note the scale we are talking about here - 0.2 micron is one five thousandths of a millimetre, i.e. 7.9 MILLIONTH of an inch. The tracks on the PCB on that clock are at least 1000 times bigger. i.e. Forget about it. So, like all engineering and other problems: 1. Establish whether you actually have a problem or whether what you are observing is expected behaviour 2. If indeed you believe that you have a problem, quantify the behaviour (measure temperatures etc.) 3. Speak to the designer to resolve the issue - give him that data from item 2 - , and... 4. ... if that doesn't work, return the product for a refund (assuming your haven't done anything silly like drill holes & fit a fan). 5.

[neonixie-l] Re: OT: "ShellShock" bash shell vulnerability...
The world will never entirely switch to node.js - the simple fact is that most ISPs worldwide do not provide node as an option, let alone as the default option - Apache is the default, CGI is dominant due to its simplicity and Bash is the default shell. The sheer mass of Apache CGI sites means that node won't be dominant for many years yet, if at all. I stated in the OP that embedded Unix uses ash rather than Bash by default (it matters not one jot that its BusyBox or some other Unix variant), and FWIW, the Bash vulnerability goes back way more than 4 years - its pretty much been there since inception - certainly more than 20 years in the GNU chain (which is the one that everyone, including Apple, uses). FYI - dd-wrt is based on the original GPL'd Linksys f/w which uses ash as its shell. Nick On Saturday, 27 September 2014 20:22:13 UTC+1, Dman777 wrote: > > I use dd-wrt firmware on my router.

[neonixie-l] OT: "ShellShock" bash shell vulnerability...
Genuine 10/10 nastiness for web-servers that use Bash CGI - you have all probably heard about this one - its potentially far far worse than the OpenSSL HeartBleed one... This is what I sent to all our staff yesterday: *Introduction* Many of you will have read about this in the press. For those that haven’t, the simple summary is that the Bash shell that is used to execute CGI requests on most of the world’s web servers has had a huge and easily-exploitable hole in it for 20 years. As everyone uses the same version of the Unix toolchain, everyone uses the same “Bash” and thus all Unix-based are equally vulnerable. Its rated as being far worse in real terms than the “HeatBleed” SSL issue, in that rather than “just” being able to trawl the memory space of the remote web server for username/password combos or private RSA keys, you can basically do what you like - you can execute arbitrary command in the context of the remote shell – it’s really easy/trivial to exploit this bug – examples in the link below. RedHat have probably the most concise description of this issue – see [url]https://securityblog.redhat.com/2014/09/24/bash-specially-crafted-environment-variables-code-injection-attack/[/url] Note that the fix that was originally posted was incomplete – a new fix is yet to be delivered. *How does this affect me?* Possibly a lot, in that sites that you access and which have your data stored on them may well be completely open to attack. If you run your own web sites (nearly all run some variant of Linux), you should replace your Bash as soon as an approved fix is available. However, there is nothing you, as a client browser, can do to lessen your chances of being indirectly affected by such an attack – its server-side only and therefore up to each Unix-based website that used Bash-based CGI scripting to implement the fixes ASAP, or to simply disable Bash CGI until the fix is made. This is being actively used in the wild already - a botnet was discovered within hours of the announcement - cunningly, it uses wget or curl do download the botnet precursor, does a chmod 777, ten executes the downloaded code to subvert the host and add it to the botnet.

[neonixie-l] OT: Anyone used an RTOS in anger?
I'm looking to use an RTOS for a project, but I'd like to exchange a few off-board emails about the pros & cons of the main offerings. Currently, I'l looking at Contiki, TI-RTOS, freeRTOS & tinyOS - my taget is probably msp430x-based. Any of you engineers worked with one or more of these?

This is a paper from Buckinghamshire Trading Standards on the risks of cheap adapters, even if they have what purports to be a "CE" mark.

Re: [neonixie-l] Digest for neonixie-l@googlegroups.com - 3 updates in 2 topics
Reprogramming the GPS module is not enough - the electrical interface to these clocks is different to the miniDIN-6 connector used by the GPS puck. Whatever path you take, just reprogramming the puck is not enough - mechanical changes are needed that are probably well beyond the capabilities of most of the owners of these clocks. The board I was proposing would not need an extra PSU - it would run off the same supply as that given to the GPS puck - and I doubt that it'd be more that 2cm x 2cm in size (by far the biggest component would be the miniDIN-6 socket, though even that could be an in-line version) - the pcb could be just sealed with heat-shrink and be inline with the cable - in-line miniDIN -> tinyPCB - > BNC for clock.

[neonixie-l] Re: Compatible GPS receiver for a Nixichron?
It'd be *FAR* neater to program a tinyAVR or small PIC etc. to take the Haicom/whatever NMEA sentences and massage it into a form that can be used by the clocks - this would cost peanuts, would mean no changes to the puck or clock and could be resold to the owner of every affected clock as a completely painless upgrade.

Two bits of ply glued at 90 degree to each other. At one end, glue a strip of wood at 45 degrees to the other two such that one side of the strip intersects with the vertex of the two other pieces.

[neonixie-l] Re: Anyone have access to neonixie files?
FWIW, I'd prefer that we used some public storage area rather than someone's private server as doing so can avoid "unexpected consequences" in the future (you can see where I'm going on this - we've had some unfortunate experiences in the past). There is a potential issue with copyright - the files were uploaded to the old Yahoo! neonixie-l group with the general intention that that is where they'd live - it's very likely that most of the owners of those documents don't care what becomes of them, but one thing is for sure, they're not de facto in the public domain and devoid of copy restrictions. So, I would be happier if we had a Google-hosted (as per this forum) or similar solution - lets have some ideas from the mods and forum members...

I have contributed substantial parts of this article over many years, but now its so hacked about that it has lost its structure and the use of English, in part, is not good. Actually, I'll go further - it's poor, contains errors and lacks cohesion. Over the next few weeks I'll seek to completely rewrite this article with a better structure, improved use of English, no duplication, expanded references etc. If others feel that this is not appropriate, please contribute below; if you feel something is missing and needs to be added, please say so.

Re: [neonixie-l] Question on Z5660M Tubes- What kind of gas and age survival?
More recently, a posting about the details of handling Kr doped tubes... https://groups.google.com/d/msg/neonixie-l/WutNWZBDMAo/WVOJ-VmwNBoJ The tubes had 0.5 μCi (micro-Curies) of 85Kr (half-life is 10.7 years) - a tiny amount. Generally, 1milli-Curie ingested will be fatal - so that's about 2,000 5092A nixie tubes when they were "hot" off the press - today, assuming the tube was made in 1970 (the 122P224 tubes I have are dated around there), that original 0.5 μCi would have decayed down to 0.028 μCi (overwhelmingly by β (beta) decay at 687 keV <http://en.wikipedia.org/wiki/KeV>), i.e. only 5.7% of the original radioactivity remains (see http://www.radprocalculator.com/Decay.aspx or http://ordose.ornl.gov/decay.cfm) 1 μCi = 3.7 × 104 disintegrations per second. Decent UV light (shorter wavelength = higher energy) certainly helps striking, IME. In the absence of daylight, you need something to kick the ionisation off - Panaplex devices had a keep-alive cathode to help, as do a lot of cold-cathode trigger tubes...

[neonixie-l] Re: Frosted Metal Case Instead of This Shiny One?
...should have added that if you are in a really humid atmosphere, you may need to re-passivate the stainless steel with some Nitric Acid - Google for the method - basically, SS doesn't corrode largely because it has a layer of CrO2 on its surface - when made, the SS is completely de-greased and then pickled in Nitric Acid - this removes any free Fe from the surface leaving the remaining Cr ions to react with oxygen to produce a layer of Chromium Oxide a few molecules thick. 4Cr + 3O2 → 2Cr2O3 In a dry atmosphere, the newly brushed SS will form its own passivation layer in time... You can "matt" the surface with Hydrofluoric Acid (i.e., micro etch it) - this works well but not all SS is the same and micro-etching is not suitable for high-Sulphur steels (303 grade) and low-Nickel grades (400 series).

[neonixie-l] Re: Frosted Metal Case Instead of This Shiny One?
Its not called "frosted" - the standard term is "brushed". Easy to do. Take off the current shiny case. Get some fine "wet and dry" paper (stuff that is waterproof), a block of cork or other wood about 3" x 2" with rounded edges and some light mineral lubricating oil (like "3-in-1"). Wrap some W&D round the wooden block, wet it with the oil, and using long (full length of the piece), straight, strokes work in one direction on the piece, not lifting the block off until you've run over the end (else you'll break up the nice lines). You could convert this from smooth to brushed in maybe 30 minutes. HTH Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

I still think the best bet is to ask him... Cheers Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.

[neonixie-l] Re: Chronotronix V400 clock dead power supply
Most MAX1771 designs are remarkably similar - whilst failure is rarae, its generally down to a few possibilities... - The MAX1771 failed and is keeping the FET on, which cooks it as the current limit resistor (if used) with be ignored. This will also cook the inductor. - The FET fails with D-S short. Similar symptoms to the first mode - The supply, if designed and running properly, should not be capable of being overloaded - it has a current limiting resistor. - The inductor has an internal short (rare failure mode). - The inductor has been replaced with one whose maximum DC current is too low - for most nixie PSUs, at least 1A capacity is required - For some reason, there is high frequency parasitic oscillation in the PSU - MAX1771 designs normally run at about 60kHz - if the thing has parasitic oscillation (typically in the MHz region), the FET will cook. Have a look at my MAX1771 page ( http://www.desmith.net/NMdS/Electronics/NixiePSU.html) for pretty much all you need to know about them along with recommended components.

Partly as a result of that visit, my younger son is now doing a Civil Engineering degree :) Nick -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
