Alas,  but I only have red HeNe...  Forgot the Kimmon HeCd though!  It
doesn't fire,  but I haven't tried hooking it up to a proper 240 outlet yet
vs a transformer,  or trying a violet ray to help ionize the tube. I was
able to get a response from a guy at Kimmon who said that model is the one
most likely to still lase.  They were used in silicon wafer machines.  When
it's powered up,  the starter arcs every few seconds.   The first time I
tried it,  it pulled white in the plasma tube a little.   Not sure if the
He pressure is too high.

Arcade cabinets are original Crystal Castles and Subroc 3D.  Have Boom'r
Rang'r conversion board kit in a vertical monitor Data East cabinet and a
Tetris board in a convertible cabinet that might have been a Heavy Barrel
originally,  and a 1982(?) DigDug cabaret cabinet with a 60in1 board
(harness adapted to JAMMA std).

I've scanned several carousels.  Still have some LPs like that too.  And (of 
course) laserdiscs of films that won't be released on DVD.

I have a ruby rod, but not a working laser yet.  The usual assortment of HeNes 
(including yellow and orange and a tunable I need to repair), as well as some 
argon, krypton, and a helium cadmium for variety.

I used to work with CAMAC and NIM stuff, I think all I have left at this point 
is a power supply.  I do have a dekatron prescaler that's available.

I have built a few replica movie props, and helped out on local productions.  
It's Halloween all year at my house.

I've gotten rid of all my arcade video games, but still have a couple of

The same thing crossed my mind. That's as far as it will probably get. Much 
more pressing is the need to dub off piles of cassette tapes (many in Dolby-C), 
four different kinds of camcorder tapes, Thousands of 35mm slides (I have a 
5000DPI scanner and a couple of carousels ready to go for that project), a few 
LPs that were never released on CD...and I need to rip my entire CD collection

> lasers (HeNe, Ar-ion, ruby, YAG, diode, dye)

Dibbs. I have lots of HeNe tubes and power supplies, including several 544nm 
green tubes and my treasured 594nm yellow (actually slightly amber). All I'm 
missing is a 612nm orange. I've been watching eBay for over a decade and I've 
seen a grand total of two plus a multiline that may be up right now (if you 
have to ask...)


> nuke gear incl 8 full NIM crates and another 100 or so modules

I'll take the decimal display scalers as long I can also get a cage, power 
supply and enough info to power the thing up and watch the lights blink. I know 
it's asking for the moon but some way to use them as generic-purpose counters 
clocked and reset with TTL signal would be the cherry on top.

I've seen two scalar modules with that display on eBay. I own one model and 
have the service manual for the other. Unfortunately, the counter+display 
itself appears to be a self-contained sub-module and the manual only goes over 
the basics of interfacing it with the rest of the device. The internals are 
given cursory overview sufficient to be a maddening tease. If anyone has the 
docs for THAT I'm all ears.

I don't own a movie prop agency, I just need more stuff for my Halloween 
display. I have plenty of the "regular" spooky stuff but I'm really into the 
mad scientist look. That's why I need to know to hook up some of those MTX-90 
keypads.


> arcade games (yes the real ones, only 5 cabinets though

Sadly, I had to unload all that some time ago. My beloved Atari Tempest is 
still out in the shed but paid for. It has the original, very rare marquee 
that's the same cartoonish style as the cabinet. All later production switched 
a marquee with artwork that looked airbrushed. It also has a set of boards that 
are geometrically perfect. No pincushioning.

I also have a set of EPROMs that have "holes" (the term only appears in the 
service manual) redrawn into different shapes. Some of them are NSFW.

Having said all that you can probably spiff yours up with information online 
but when I bought it for $65 thrity-three years ago this was a big deal.


> but also Atari 2600 and Colecovision and a few old Zenith TVs for spare CRTs 
> for the monitors), maps, books, books, and more books...

Yep, yep, yep. The only console video game I ever owned is a real oddball, 
Atari Breakout. It's 100% just like the actual arcade game plus some other 
modes. I say "is" because I still have it in the original box with all parts 
and documents. I have no idea if it still works but the pot and switches need 
to be replaced.

Sadly, I had to throw away a big pile of computer and electronic magazines 
because they were badly water damaged. Among other things I had the full run of 
SoftTalk magazine, which was THE Apple ][ magazine for a while. It was worth at 
least a few bucks but the sentimental value was much greater.

I have a well illustrated tube-era Electronics For Beginners book where all of 
the illustrations have cartoon electrons (with arms and legs like an electric 
company mascot) literally running around schematics that were drawn in 
orthogonal perspective and, IIRC, 3D extruded. I only mention this book because 
out of everything I scarfed up at hamfests it's one my hamfest/arcade game 
buddy is the most envious of. 8D

gave me one a few years back. And a 7971 several years before that.

Re: [neonixie-l] Re: Nixie porn

[Nick Andrews]

Don't laugh, but I recently threw out a pile of 486 stuff, mobos, proc,
even PIII, etc.  And a couple of 8086!  I recently bought a usb floppy
drive because my HP hybrid scope has one in it for storing traces and such
and also to upgrade firmware, etc.  I actually started an inventory of my
radiation and lab gear, with permanent ID labels, S/N, etc.  Intended to
add a picture in a spreadsheet so when I croak, someone could recognize the
value in portable gamma spectrometers and such and not toss them.  Maybe
not worth $20k new price, but still...  Lotsa Ludlum gear, Amptek Si-pin
spectrometer too, around $8k new for just that one (not to me, of course).
A small sampling:  lasers (HeNe, Ar-ion, ruby, YAG, diode, dye), metal
lathe, vertical mill, metal shaper, nuke gear incl 8 full NIM crates and
another 100 or so modules, woodworking, metal working, welding, auto stuff,
water gardening (water lilies, lotus, all sorts of bog plants, fertilizers,
etc), photography (yes, wet B darkroom with lifetime supply of chemicals
and 3000'+/- 35mm films, Graphic View 4x5),
guns/shooting/reloading/gunsmithing, chemistry, rockets, pyrotechnics,
hunting, gardening, motorcycles, 4x4s, general construction and repair,
arcade games (yes the real ones, only 5 cabinets though but also Atari 2600
and Colecovision and a few old Zenith TVs for spare CRTs for the monitors),
maps, books, books, and more books...

I have a tiny black hole in my basement that constantly needs filling. So far 
it has resisted almost all attempts to remove a few Plank constants.

I have a large analog plotter that goes with an old HP "calculator". Unlike 
most of my collection I'd be willing to part with for a reasonable sum of 
money. I've never gotten around to putting it on eBay because I don't know what 
constitutes "reasonable". For all practical purposes it's literally a museum 
piece just like the calculator.

I'm open to offers or at least appraisals. I can't just give it away to a 
non-profit organization because

A. I don't pay taxes and can't use it as a tax deduction;
B. The quite large PC board is heavily gold-plated including the component 
leads. As scrap it's probably worth a tidy sum.
C. It appears to be fully functional. The servos slew properly over the entire 
work area, the electrostatic paper "holder" works, and the pen goes up and down.

Hamfest? Sidewalk? Hmm...

Hah. You have to have very specialised interests. I often think nobody will
know what do with my stuff but I just offered a old HP floppy/hard drive
(that I'd been sitting on long after the HP85 computer had gone) to the
VintHP group and I was amazed to find they nearly bit my arm off for it.

RE: [neonixie-l] CRISTAL + CAPACITOR = TIME DELAY HELP

[Bill van Dijk]

Without knowing your exact design I cannot recommend a specific xtal. For 
instance, PIC processors recommend a xtal with a load capacity of about 12pF, 
while other designs are optimized for different xtals. Often the devise data 
sheet will give you a short list of recommended xtals which have been tested by 
the chip designer. The main thing is that for critical applications (such as a 
time keeping devise) always get a good brand name item with full 
specifications. Often xtals used for running a program are not critical, so 
there you can sometimes get away with something cheap; as long as it runs, and 
is close. I am a great proponent of recycling, but saving 32kHz clock xtals is 
not worth the trouble. Xtals are complicated; there are different cuts and 
styles, all specific to particular applications. 

 

There is a great app note from Microchip worth reading:

http://ww1.microchip.com/downloads/en/appnotes/00949a.pdf

 

Even Wikipedia has a decent chapter on xtals:

https://en.wikipedia.org/wiki/Crystal_oscillator

 

Lots of other good information sources on the interweb.

 

Cheers, Bill

Hello Bill,

 

Thanks a lot for your answer and your knoledge, 

 

I will do a chart with different capacitors values and I will see how the time 
delay get's. I'm using two capacitor to ich leg of the cristal.

 

as you say, my cristal is not that good, do you recommend a cristal in 
specific? 

 

thanks a lot!

If you are still slow with the 10pF, a 12pF is not going to do it. The 
relationship between the crystal and load capacitor is critical, and it is 
therefore a mystery to me that so many (of the cheaper) are sold without the 
specifications. Anyway, if yours is a cheap Chinese crystal, try some other 
ones, perhaps you just got a bad one. Generally I always like to get a good 
brand name crystal. If you want to play with the one you have, try something 
lower yet, 8 or 7pF.

 

In general terms, and within limits, larger cap slows it down, smaller cap 
speeds it up. Sometimes (if you use 2 caps) using a slightly different cap on 
one leg of the crystal can make a difference in the final frequency.

Hello Guys! 

 

I have a nice question to ask you guys if you can give me some help.

 

I builded a Nixie watch, It works good, but I'm having a little bit of time 
delay, 1 min within 6 hours. 

 

At the first time, I had 6 min delay for 6 hours aproximately. I investigated 
the relation of the cristal and the capacitors you need to install with it. 
First, I had 22pF for a cristal that requires 12.5pF, giving me that 6 min 
delay for 6 hours, then, I realised these and installed 10Pf capacitor and the 
delay decreased to 1 minute for 6 hours, and I just ordered new capacitors of 
12pF to get more closer to the manufacture requires, So I imagine that the 
delay is gonna get less. 

 

·Is there any way to make this time delay shorter? 

·Do you recommend me a tipe of cristal that is really acurate to install on my 
watch?

 

 Thanks a lot nixie lover's

Re: [neonixie-l] CRISTAL + CAPACITOR = TIME DELAY HELP

[gregebert]

The DS3232 has an internal crystal, with periodic temperature compensation 
(every 100 seconds). There are also non-volatile trim registers that allow 
you to fine-tune the trimming even further, though I have not needed to do 
that.

You wont be able to use a scope to fine-tune the crystal oscillator, 
because the scope wont have sufficient precision or accuracy. A frequency 
counter is a starting point, but in the end you will need to measure the 
time over a period of days to get it accurate.

Many years ago I had a clock-calendar in my S100 computer, and I would 
tweak the trim capacitor every few days. After a week it was really close. 
There were no cellphones, GPS receivers, or NTP servers to get the time; 
you had to call the phone company for a recorded message with the time, or 
catch a radio/TV station identification.

Hello David! 

that's awesome, I really like the idea, I just bought an oscilloscope but a 
really cheap one, the only one I could affort. 

I will try make some change's on the watch to catch a Via to connect the 
oscilloscope to it and take a good look to the frecuencia to try to get 
that 32.768 KHz  frecuency. 

I love the idea of the variable capacitor, it is a really really good idea 
guys.


Thanks a lot for the comments, now I have more ways to keep studiying this 
methods and components.

Hello! 

that's crazy!!!  haha

Yes, I was thinking to put a RTC on my watch, but it is more space. that's 
my second option If I dont fix really good the time delay. 

But, as I know, With the RTC for example DS3232,  you also need to put an 
external cristal right? so, does theDS3232 regulate this time delay in any 
form? 

thanks a lot!

[MrThe50sanchez]

Hello Bill,

Thanks a lot for your answer and your knoledge, 

I will do a chart with different capacitors values and I will see how the 
time delay get's. I'm using two capacitor to ich leg of the cristal.

as you say, my cristal is not that good, do you recommend a cristal in 
specific? 

thanks a lot!

[blkadder]

I am truly floored.  Someone out there must have a gigantic horde of 7971 
tubes to send someone 14 of these giants.  Well, I am subscribed to the 
channel now.  I am looking forward to see what Fran comes up with  for this 
amazing collection of tubes.  I wonder if the anonymous sender is in this 
group?
