Re: [neonixie-l] Alarm Clocks and ChatGPT

[Dylan Distasio]

A quick follow up, it would appear Claude2 is also making mistakes.   I
checked the Sony and it was actually a pocket radio.   Here's what happened
when I challenged Claude2 on it:
You're absolutely right, my previous example of the Sony TR-610 was
incorrect. The TR-610 was a transistor radio model, not an alarm clock.
Thank you for catching my mistake!

After further searching, I could not actually find documentation that Sony
made any all-transistor alarm clocks without integrated circuits in the
early 1960s era.

I made an invalid assumption based on their early transistor radio
products. I sincerely apologize for providing an incorrect model number and
claim about an early Sony clock using solely transistors. As an AI
assistant aiming to be honest and factual, I should not have fabricated an
example. Please let me know if there are any other responses of mine you
would like me to correct or clarify.

Re: [neonixie-l] Alarm Clocks and ChatGPT

[Dylan Distasio]

Just my two cents working with LLMs a fair amount...They are all prone to
hallucinations when they don't know the answer.   With direct access to the
LLM, you can reduce this sometimes by lowering the "temperature"
parameter.   You may be able to approximate doing this through prompt
engineering with the chatbot.   You can firmly instruct it not to make up
responses if it doesn't know the answer.   You will also find if you
challenge it on a wrong answer, it may either provide a correct one, just
apologize and agree with you, or provide another wrong one.   How you
phrase prompts can be very important to results received in general.

If you have any ebooks/documents with any related history, you can also
upload them to the chatbot to enhance its understanding of a niche area on
the fly.  This is what is known as Retrieval Augmented Generation (RAG),
and can greatly reduce hallucinations and deliver accurate info based on
the uploaded materials.

FYI, if you are going to upload anything, I would suggest potentially
taking a look at Claude2 as last time I checked it has a much larger
context window than GPT3 (You may also want to check out GPT4).   The
context window determines how many tokens the LLM can pull in to work with
from what you've uploaded (which ultimately determines when something is
too big for it to ingest).

Alphabet's Gemini 1.5 which will be out shortly increases the context
window to 10 million which may be a game changer (as a reference, I believe
the current context window on GPT4 is 128,000!

Just for comparison, here are Claude2's results on a similar line of
questioning...I'd be interested to hear if anyone can verify the veracity:
ME: You are an expert on the history of electronics going back to the start
of the industry. Please answer my questions to the best of your ability,
and DO NOT MAKE UP answers if you are unsure of them.

I do not actually have expertise on the history of electronics. As an AI
assistant created by Anthropic to be helpful, harmless, and honest, I will
not make up or guess answers if I am unsure. If you have questions about
the history of electronics, I can try my best to provide factual
information, but please understand there may be limits to my knowledge.

ME: Has there ever been a transistorized alarm clock (no integrated
circuits)? If not why not?

Yes, there have been transistorized alarm clocks made without integrated
circuits.

Transistors started replacing vacuum tubes in consumer electronics like
radios and televisions in the 1950s. By the late 1950s and early 1960s,
advances in transistor technology made them small, cheap and reliable
enough to be used in consumer clock radios and basic alarm clocks.

Some examples of early transitional transistorized alarm clocks from the
late 1950s to mid 1960s include:

- General Electric had some of the earliest transistorized clock radios in
1957-1958 using four transistors. They later made basic transistorized
alarm clocks without the radio using similar circuitry.

- Sears had a line of "Compact" transistorized alarm clocks in 1959-1963
that contained a small number of individual transistors rather than tubes
or integrated circuits.

- Japanese companies like Sanyo, Sony and Toshiba made some of the first
mass-produced transistorized alarm clocks for export in the early 1960s.

The circuitry was still relatively simple, using individual transistors
wired on circuit boards rather than integrated circuits. But it allowed
miniaturization and battery operation compared to tube-based clocks. They
were affordable products marking an intermediate step before ICs fully took
over in consumer electronics.

ME: Can you please provide some specific models of clocks that only used
transistors.

Here are a few specific models of early all-transistor alarm clocks without
using integrated circuits:

- General Electric 940 Trans - This was a basic 4-transistor alarm clock
released in 1959.

- Sears 'Compact' Alarm Clocks - The Ted Series and Bart series released
from 1959-1963 used transistors to make small, affordable alarm clocks. For
example the Ted 2R65 model used 5 transistors.

- Sony TR-610 - Released in 1962, this model used a circuit with six
transistors.

- Toshiba TRQ-4 - One of Toshiba's first transistorized clocks in 1962,
containing six transistors according to its specifications.

- RCA Victor 6TR29 'Personal' clock - Contained 6 transistors when it was
introduced around 1960.

So in summary, many major consumer electronics brands produced
transistorized alarm clocks with a handful of transistors, no tubes and no
integrated circuits from the late 1950s through mid-1960s. They were
interim products before ICs took over the market a bit later in the 1960s.
Hopefully this gives some relevant examples! Let me know if you need any
other details.

ME: Were there any clocks that used only vacuum tubes

Yes, vacuum tube-based clocks were used prior to the invention of
transistors and integrated circuits. Here are a

Yes.  Agreed.  I'd be interested at around $15-17.50.

Re: [neonixie-l] Re: Seen this on eBay!?

[Dylan Distasio]

I just got mine in today.  FYI, for anyone who is in the US, I neglected to
notice that this unit come set to 220V by default.  Although I am not very
good with transformers, I noted in the manual it said that the taps could
be changed, so I decided to open the case and take my chances :-).  It has
two windings in parallel, with taps for 0, 100, 110, and 117.   There was a
jumper connecting the two windings at 0/110 (for 220 total).  I unsoldered
that, and unsoldered the remaining wire on the second winding to 117V and
resoldered it to 117 on the first, crossed my fingers to avoid the magic
smoke and turned it on.  I was greeted with a nice orange glow across all 5
tubes showing zeros!  I've never actually used a FC before so I have to
figure out plugging something into it to check other digits but it looks to
be in working order as far as I can tell.

Re: [neonixie-l] Re: Seen this on eBay!?

[Dylan Distasio]

I did as well, thanks to the OP for sharing.  FYI, the seller accepted an
offer of $120 (plus shipping) from me if anyone else is considering
scooping one up from the list.

I couldn't resist, although I'm not sure what I am going to be
realistically doing with it any time soon.  In the back of my mind is the
dream of turning it into a clock of course, similar to the Evil Mad
Scientist reworks of HP FCs which still use the FC function for
timekeeping, but it may be beyond my time and abilities, at least for the
foreseeable future.

Looks great, and thanks for offering the circuit boards.  I have a set of

Good point.  BTW, just a heads up, but based on the same seller's eBay

Re: [neonixie-l] l3d-cube versus led aurocube

[Dylan Distasio]

The LEDs are WS2812Bs (5x5mm sq).

The WiFi is part of the entire brains of the operation, a particle photon
board.  You'd probably just want to swap the whole board if the wifi quit,
but in theory you should still be able to upload something directly to it
over usb from a PC if everything else was still working.

FYI, I don't have one of these but the specs are open source.  They
actually look pretty cool.

Re: [neonixie-l] Opinions on this inverter transformer for prototyping NIMOs

Thanks to all for the answers including the clarification on turns ratio.
One question though, this reads as an inverter in the listing, so I was
under the impression I could feed it DC in and get AC out.  They reference
using a 9V battery as input in the description.  Is my impression correct?

[neonixie-l] Opinions on this inverter transformer for prototyping NIMOs

[Dylan Distasio]

Hi all-

I noticed that electronics goldmine is selling compact inverter
transformers cheap, so I just ordered a few:
https://www.goldmine-elec-products.com/prodinfo.asp?number=G22744

Can on of my betters on the list advise on whether they see any issues with
using this to test a NIMO tube using a low voltage DC input?

I'm still a beginner on some of the theory side, so wanted to make sure I
was not missing a problem here.

Also, it doesn't come with a pinout, and I had heard that inverter
transformer inputs are typically on a diagonal instead of one side.  Can
anyone confirm that this is standard, and suggest a way to figure out the
pinout using a multimeter only (not sure if that is possible but I figured
I'd ask).

Best,
Dylan

reference on price, I bought 4 on fleabay in 2016 for $100 each (which
granted I have not tested due to not getting around to putting together a
proper PSU,  but I believe are NOS and working based on seller reputation,
and look in excellent condition).  Some are probably scoffing that I spent
that much without testing, but I took a calculated risk and didn't have any
way to in a timely fashion.  I'm still a piker at building my own PSUs
unfortunately.

Anyways, as a tube hoarder, I have no intention to sell them, especially
since I really do want to make a clock out of them, but a gain of over 300%
in less than two years wouldn't be too shabby!   I'm sure there are some
tube elders of mine on list laughing that I paid that much compared to
whatever they're holding, but I was unfortunately late to the tube game.

Thanks for the additional color on these.  I was debating on picking one up

Re: [neonixie-l] Re: MCU religious wars (OT?)

[Dylan Distasio]

Hi Nick-

I'm in the US, but have ordered from Pimoroni in your neck of the woods
before.  I love their stuff in general (they have a ton of cool Pi hats!),
and believe their prices in GBP are pretty close to the USD prices here
($10USD).  They may be a bit higher with VAT but shouldn't be anywhere near
double:

https://shop.pimoroni.com/products/raspberry-pi-zero-w

They're a great bit of kit for the price.

Best,
Dylan

Re: [neonixie-l] Re: MCU religious wars (OT?)

[Dylan Distasio]

Although UV erasers were before my time, I grew up as a kid with a C64, and
although it's not a 6502/10 project, I decided at one point much later in
life to build a N8VEM Z80 based computer which strove to use mostly
components from the original timeframe of the 8 bit era.  Anyways, I
actually ended up buying a cheap UV eraser on fleaBay to use on the EPROM.
 While I really enjoyed the overall build, I don't miss having to use that
to erase a chip!  Later variations on the project which I also built used
an easily flashable ROM thank god.  What was perhaps slightly lost in
authenticity was made up for in convenience .

This was the project for those interested:
https://en.wikipedia.org/wiki/N8VEM

I've also played around with these more recently for fun, although I would
still like to build a 6502/10 from scratch based on my own design to honor
my C64 roots.  I still miss my Amiga also, but now I'm just getting
sentimental...

Re: [neonixie-l] Re: mason jar numitrons

[Dylan Distasio]

Sorry, my choice of the word hate was intended to be somewhat
tongue-in-cheek.   I'm relatively tech agnostic in terms of projects,
although as a relative latecomer, I cut my embedded teeth on the Arduino,
so I'm somewhat partial to Atmel tech.  In the past though, I've done stuff
on the Arduino, and then burned it directly onto a compatible Atmel 8-bit
chip to place on a board.  I haven't actually done of my own PCBs yet
though, so I'm still a piker.

Hats off for your use of assembly, I haven't done any assembly since my
Commodore 64 days, but am hoping to get back into it at some point.

Hi All,

On ebay I was looking for this display quite a while.  I have  a few PCBs
designed for Babcock display SP-431-001 and really want to find display and
add the clock to my personal clocks collection.

I have been watching  this lot for a few months https://www.ebay.co.uk/
itm/182853730802?ul_noapp=true

and a few times contacted seller to ship it to the UK, but he never replied
to me, so I thought I would ask our NeoNixie community for help.

I am wondering,  if someone from the US could help me to  buy it  and
resend it to me to the UK address. Of cause I'll cover all expenses.


Thanks in advance, Konstantin

Re: [neonixie-l] Re: Dekatrons for sale shortly

Just as a gauge of demand, I'm interested.  Thanks for your efforts!

Once I have the stock to hand I will publish a list here with the details

demand is there then I will endeavour to get greater numbers.

As to how it will work?

I think the fairest way is to make the list public and have a dwell time of
a couple of days for as many members to peruse it as possible as we all
live in different time zones and visit the forum at different rates.
Ideally it would then be on a first come, first served basis as people
would then be able to have their 'wish lists' made by then and I will sort
it out from there.

I am in Ireland so I would post the details at 12.00 GMT a couple of days
after receipt and checking what is available for sale, all being well. As
to packaging, I am looking at small mailing boxes with bubble wrap around
the contents so postage would be at materials cost plus the relevant postal
rates for the destination bound.

[neonixie-l] Looking for advice on building a DT-1704C clock

[Dylan Distasio]

Hi folks-

I've accumulated a few DT-1704C VFDs over the years.  Although I would
rather have Y1938s with their blue tint, I also really like these tubes.  I
was thinking of either handwiring a prototype or trying my hand at spinning
my first PCB, but was looking for suggestions on a power supply IC (or
other options).

The segment voltage is 27V, and the filament is 1.6V.   I was thinking of
using 12VDC in, but am still a noob when it comes to designing power
supplies.  Is there any type of step up/step down IC someone could
recommend that would be good for outputting both of those voltages?

Thanks,
Dylan

[neonixie-l] Praise for PV electronics

[Dylan Distasio]

I'm sure most on the list are probably already aware of PV electronics, but
I just wanted to praise the quality of the IN-8 kit.  I just finished
building one for a friend of mine who really wanted a nixie clock, and he
was very excited when he unpacked it.  His co-workers all wanted to know
what it was, and how he got it.

I went with the full case and GPS attachment, and blue LEDs.Building it
also made me remember that I actually like IN-8s.  I think they look great
for a smaller, relatively inexpensive tube.

Anyways, just wanted to give Pete a shout out.

Re: [neonixie-l] Need IN-14

I've ordered a lot from Russia, and have found it is usually 2-3 weeks to

Re: [neonixie-l] Lixies/Tixie Clock

[Dylan Distasio]

No funds were ever returned, and I think you can see from his own writing
that he has no real issue with what he did.  Apparently, screwing over his
backers was a learning tool for him.

I have backed a ton of projects on Kickstarter, and fully understand that
things can go wrong and that ultimately a project may not work out
(although in all my backed projects, his was the only one where I
encountered a total loss combined with fraud).   I think that all most
backers are looking for is a well planned out best effort, and transparency
throughout the process.  In this case, there was zero transparency until
the end, irresponsible use of funds (criminal in my mind), and a lack of
remorse.  If he had really cared about what he had done, and learned from
the experience, he would be refunding his backers over time.

Anyways, for obvious reasons, I personally will never do business with him
again.  Luckily, it was a relatively minor loss financially, but the
overall experience leaves a bitter taste.

Re: [neonixie-l] Lixies/Tixie Clock

[Dylan Distasio]

I was a backer, so I will share the last update from KS (which was only
provided after months of backers pleading and cajoling for any type of
update):

Fatal Mistakes

My name is Connor Nishijima. In 2015, I set out to audit the emotions of
the earth via Twitter using a Kickstarter for Emotiscope - then known as
"Moodlight".

It crashed and burned. Here's what I did wrong.

I never planned to make it this far

I only wanted just enough funding for a small batch. Just enough leftover
to start a run on Tindie afterwards or something, so I did the math. $935
was what I needed to make a modest batch, and grow it from there
afterwards. I could handle assembly and shipment on my own in a timely
matter for that kind of run.

I hit that goal in less than 24 hours. Fuck. It kept going, and kept going,
until I was 483% over funded. My first fatal mistake was never planning for
this before starting. I didn't know how to fulfill that size of an order
yet.

Irresponsibility with funds

I own a 2008 2nd Gen Prius. It's a wonderful car, but it had a hiccup.

Driving on a freeway, the car would slow down on its own. No dash warnings.
I turned off the air conditioner and radio. The car kept slowing down and
losing power. It went into safe mode, then all the dash warning lights went
on.

After taking it to a dealer, the regular service tech couldn't figure why
it was failing. There were no codes being generated upon failure. The
dealer got a master tech from Toyota who went over the car and said it was
fine. After the first service tech and I witnessing the failure, I wasn't
confident taking the car. The master tech said he would try driving it
again. After a 20 minute drive, the car failed again.

The diagnosis from the master tech was to replace the Hybrid, Power and the
Transmission Computer. This totaled $1,660 in parts and $1,428 in service.

I had $1,700 of my own savings on hand, but I still needed another $1,300
to cover the cost. My girlfriend at the time didn't drive or work, so this
was the only way for either of us to afford our roof. At the time I was
making ~$1,500 a month at my job, so I figured this would be easy to fill
in with some help from family. I pulled $1,300 from the KS fund, with the
idea of paying it back in within a month. This was my second fatal mistake.

That company I worked for was the original RadioShack. (Now General
Wireless DBA "RadioShack") After filing their Chapter 11 bankruptcy in
February that year for a restructure plan with Sprint's parent company,
they got the approval in September. In October 2015, RadioShack cleaned
house of over 80% it's hourly-waged employees to bring in existing Sprint
staff for massive downsizing.

Now I've fixed my car, and I have no income source. During following month,
I had to live off of KS funds, until landing as an Electrical CSA for
Lowe's, for about the same wages.

So my life was back on track, but now I'm out $1,300 car fund, and $800
rent.

I was making about $1,400 a month on average at my new job, and this wasn't
enough.

Rent - $800
Groceries - $100
Gas - $20
Heating - $80
Electrical - $60
Water - $40
Verizon - $110
Comcast - $60
Pet supplies - $20
Total: $1290

At the end of every month, I would only be left with about $110. At that
rate, it would take 19 months to refill the KS fund to it's original
status, so I knew now that the entire profit margin was gone and I would
have to sell at a loss.

I had no fulfillment company

One thing I realized very quickly after it was too late, was that anyone
whose ever comfortably "made it" on KS used a fulfillment company to handle
shipping. There are companies designed where you can ship your entire stock
to them, and an address list. They charge $2-5 per order, and move
shipments for you. I didn't have one on retainer, because I never expected
the massive overfunding. But I couldn't afford that fee, as things were
already in the hole.

I wasn't cautious with large order proofing

"Might as well keep up appearances", I thought. I pressed on, making a
final revision of the boards, double checking it, and ordering 120. I
checked every trace, and all was well. But this was my third fatal mistake
- I did the mass order without a proof. By forgetting to change out the DRC
of the more-expensive and capable OSHPark fab, I gave a board to a Chinese
factory that couldn't match the OSHPark standard my board passed during
checking. As you may recall, 120 boards arrived with a short to ground near
the LM317, causing it to overheat, overdraw current, and quickly destroy
any USB port they were plugged into. This was a $574 loss.

I kept changing the product after launch

I was starting to make a little more money on the side with some graphic
and web design consultation, so I was able to make back a lot of the
missing money. So I got cocky. I wanted to make the wait worth it for my
backers, so I refined the prototype unit seen in the video to a slimmer
model, with a faster processor, and a painted, translucent 

Re: [neonixie-l] Lixies/Tixie Clock

[Dylan Distasio]

While I do agree that this looks cool, I would point out that the creator,
Connor Nishijima, defrauded Kickstarter backers on his prior ill-fated
Moodlight project.  He admitted to using the backer's funds to pay for car
repairs, and nothing was ever delivered, nor was there any attempt at
making it right with backers.

Are you asking specifically about how to get the different required

place?

If the latter, this is a pretty well explained datasheet:

[neonixie-l] Great article on Mr. Parry's amazing work

[Dylan Distasio]

I've seen a lot of it here, but what gorgeous clocks, truly works of art:

http://dornob.com/clocks-dont-get-more-bonkers-or-beautiful-than-the-bad-dog-designs-nixie-tube-clocks/

...
A career in electronics and a childhood of taking his toys apart and
putting them back together again to greater effect has lead Parry to really
coming up with the goods this time. In the past, Nixie tubes, also known as
“cold cathode tubes” as they have no internal heater and are cold to the
touch, would have been hidden away within equipment — like old fuel pumps —
but now they are a prominent feature of Parry’s clocks. Tiny metal pieces
all stacked together create numerals which emit an orange, gloom-like glow
when given an electrical charge, all encased in glass tubes and looking
like something that would be at home in a 1950s sci-fi movie. Or a Hammer
House of Horror film set in the basement laboratory of a crazed scientist.

Re: [neonixie-l] Re: Any large tube clock kit recommendations

Thanks for the suggestions.  I ended up going with PV but with IN-8s and a
nice acrylic case and GPS.  I couldn't make anything larger work in the
budget I had, and my friend is happy with the choice.  Now I just need to
build it.

Do you guys ever ship clocks with tubes in place?   I'd rather spare him
the minor hassle of fitting them.

I would second the choice of Pete's kits having built quite a few now. I
have a Spectrum kit built and ready for case decoration but my preferred

Why not make your own case such as this one Imade for the Spectrum kit from

[neonixie-l] Any large tube clock kit recommendations

[Dylan Distasio]

Hi folks-

I'm trying to help a friend put together the nicest nixie clock possible
for between $350-500 with tubes.  I'm willing to build it from kit for him,
so through hole (and relatively easy SMD) soldering is fine.  I need some
kind of case, although acrylic is fine and he likes the look of it.  He
loves the Zen clock (who doesn't?!) but doesn't want to spend that much.
I'm basically looking for the biggest tubes possible at that pricepoint
range with some kind of enclosure.  I'm willing to source the tubes
separately but won't have any magic cheap supply for them and will be going
through fleaBay or somewhere readily available so I do need to include the
tube cost in the total price.

Any suggestions welcomed.

Re: [neonixie-l] Re: Rare Nimo Tubes

[Dylan Distasio]

Does anyone have experience undervolting these to 2kV?  I see on the
datasheet that this moves it significantly down the brightness curve, but
am wondering how noticeable it is in practice.

I was thinking of picking up an Emco F20 PS which while not as cheap as I'd
like seems like an easy way to get 2kV for a noob.  The next model up is
3kV and I would rather not overvolt as I'm concerned it will shorten the
tube life (not sure if that is actually true if current stays the same
though).

Thanks,
Dylan

Re: [neonixie-l] Re: Rare Nimo Tubes

[Dylan Distasio]

I took the bait and picked up 4 of these to add to my future projects
pile.  That said, I've never experimented with voltages beyond the dekatron
range.  I don't know that I'm interested at this point in building my own
kV PSU (although I would be eventually).  Can anyone recommend a relatively
inexpensive off the shelf PSU to drive these with?  According to the
datasheet, I should be looking for 2.5kV on the anode, with 1.1V on the
filament.  I'm not sure exactly how to drive the grid.  Does the grid
consist of the cathodes?  Apologies, but I have zero CRT experience at this
point, and any pointers would be appreciated.  I'd like to at least be able
to test these when they come in.

Thanks!

I agree, awesome project, but I wish he would have used another tube.

Re: [neonixie-l] Cogwheelcircuit

Speaking of which, are there any other b7971 kits out there that people are
aware of? I have the tubes and sockets, but haven't gotten around to
building a clock with them from scratch.

[neonixie-l] DT-1704C sockets

[Dylan Distasio]

Hi all-

Does anyone know which socket to use with DT-1704C tubes?  It looks like a
9 pin mini but I was hoping to confirm.

Thanks!

-Dylan

Re: [neonixie-l] b7971 request

[Dylan Distasio]

Thanks for the input.  In the interest of not breaking the bank, I am only
looking for two tubes at this point (I already have two).  I was hoping
someone on the list might have a few extras they'd consider parting with.
I had already checked eBay and am watching the auction for 4, but figured
it wouldn't hurt to ask, especially since the trust factor is higher here.

[neonixie-l] b7971 request

[Dylan Distasio]

Hi all-

Apologies in advance for annoying anyone with this request, but I finally
managed to grab a couple of used b7971 tubes at a somewhat reasonable (all
relative I guess) price.

I was wondering if anyone had 2 extra b7971s (used in decent condition or
NOS) that they might be willing to part with.  I am trying to get up to 4
total for the usual reasons :-).

Please contact me offlist if interested in discussing this further.

Best,
Dylan

Yeah, I understand the pricing, just wish I could afford one along with

I've never built one and would love to start with yours.

[neonixie-l] IV-1 help needed

[Dylan Distasio]

Hi folks-

Hoping I can get some assistance with driving an IV-1 VFD (dot dash) tube.
I have still not gotten around to building VFD circuits on my own from
scratch (I've built a few kits), so do not have a great handle on this.
I've tried to muddle through the Russian datasheet but have not fully
translated it.

I figure someone here must be familiar with these for separators in VFD
clocks.

Let me start with pinouts.  If I am reading the datasheet correctly, I
believe:

Pins 1,8 are the filament

Pins 2,3,4,5,6,9,11,12,14 are not connected.  Does this mean they are
literally not connected, and are just there for physical support or can be
clipped?

Pin 7 is the grid

Pin 10 is the dash (anode)
Pin 13 is the dot (anode)

Assuming I have gotten this far without an error, can someone confirm these
voltages?  I may be really off on what I am assuming is what, since I have
not fully translated this.

Pin 1- 0V (ground)
Pin 8- 0.85V
Pin 7 - 20V
Pins 10,13 20V

I am unsure how to read the current limits on the datasheet.

Apologies in advance on any ignorance or mistakes, and thanks for any help.

Best,
Dylan

Re: [neonixie-l] Thoughts on building an ITS1-A clock from Mr. Nixie's kit

I agree, I do love the tubes.  I wish they were a bit more affordable, but
that's a lament across the board on most of our stuff.  I always learn
something new on each build whether it is from a kit or scratch.  I did not
know how irregular the shape was on these until I got started on this one.

[neonixie-l] Thoughts on building an ITS1-A clock from Mr. Nixie's kit

[Dylan Distasio]

So I just finished putting together an ITS1-A clock from Mr. Nixie's kit.
I ordered the tubes separately on fleaBay.

The kit is very well done, but I ran into a couple of pain points I thought
I'd share.

The first has resulted in a finished product that pains me a bit from a
cosmetic perspective.  I was not aware of any size differences in
individual ITS1-A tubes based on manufacture date (or whatever else).  I'm
not sure if ITS1-As vary from 1-Bs and if somehow I got a mix of both on my
eBay order but some of the tubes slid cleanly into the cutouts from the
kit, and some did not.  Unfortunately the first ones I was working with did
not, and it was not until I got to the 3rd digit that I realized some did.
Since I was not up for attempting to resolder the tubes already done with
their leads clipped, I am left with different depths on the digits and the
angling is not perfect on the ones that did not fit flushly into the
sockets.  It does not look horrendous, but I am kind of a perfectionist
with these things, so it is driving me a bit crazy.  I've tried to make my
peace with it though, and have moved on for the most part.  I still love
the clock, and am just happy it is working at this point, which leads me
into...

The manual specifically calls out how fragile the leads can be on these
tubes, and prone to breaking.  I had ordered 8 tubes originally to have
some spares.  Despite my best efforts in babying the leads while
straightening them out, it was with much horror that I saw one break off
near the glass.  I spent a very long time attempting to jury rig the broken
lead back on but eventually gave up as I could not get conductivity after
soldering it back into the board.  After giving up, I used one of my spares
as a replacement.

I continued to solder away and got to the final tube of 6.  After hooking
up the clock for testing, I was dismayed to see two of the segments
refusing to light.  I doublechecked all connections on the leads,
resoldered, etc. and despite everything I tried I could not get those
segments to light.  I eventually admitted defeat and hooked up my last
spare, which of course did not light (I did not have a tube tester at the
time of purchase).  At this point, I was pretty frustrated with the
experience.

To add insult to injury, I had also gotten sloppy when moving the live
board during testing and managed to give myself a nice 270V shock when I
made contact.

After ordering two more tubes on eBay, I waited patiently for them to
arrive from overseas.  They just arrived, and after carefully bending the
leads outwards, and soldering in the last one, I am now the proud owner of
a slightly askew working ITS1-A clock!

This turned out to be a very expensive project.  I am happy with the unique
nature of the tubes and the wonderful kit from Jurgen though.

Re: [neonixie-l] Thoughts on building an ITS1-A clock from Mr. Nixie's kit

[Dylan Distasio]

Thanks!  The separators are a plastic rocket shaped red LED.  They can be
set to blink also, or just turn on for AM / PM.  The clock has a lot of
nice features overall including temperature, light sensing, and the ability
to set any rgb color on the backlight LEDs.

 After 2 years of work, I finally finished my first (and only) nixie
 watch... OK, so it's panaplex watchwhatever.
 I still dont know how long the battery life is. When I did accelerated
 battery-life testing on my demo board a few months ago, it  extrapolated to
 about 2.5 months. So far, it's gone a bit longer than that on a full-charge
 and there's still a nice charge on it.

 The sad story about this watch is that *after* I sealed the case (yep,
 permanently...), then the charging terminal for the battery developed a
 broken connection. Murphy's LawSo I must either destroy the handmade
 plexiglass case, which took many hours to build, or drill some tiny holes
 into it so I can pin-probe the battery terminals to charge it.

 It's a ridiculous thing to wear because of the size and weight; I'll see
 what the other engineers at work say about it tomorrow. They think I'm a
 tad kooky to design a watch with a 40+ year-old display when my day-job is
 designing 10nm ICs.

 Heh-hehnotice I didn't show how tall the watch is in the photoit
 aint no iWatch. Probably 1 inch tall.

 I just finished it in a nick of time, too. My wife and I saw
 Tomorrowland last weekend and she was awed by Goerge Clooney's IN-18
 nixie clock and gave me an assignment to build one for her. Definitely the
 best task on my honey-do list..will it really be 12 tubes, or only 6.
 Still pondering that.

I'm interested.

neonixie-l@googlegroups.com wrote:

 Ok, so I went ahead and started designed my own clock, borrowing heavily
 from an existing open source design.

 Here's what it entails. I have IN-18's and love those tubes, so naturally
 it uses them. I designed a main module that has the Arduino interface,
 power supply, control logic, 2 anode drivers, and 2 IN-18 tube socket
 footprints. At the end of that module there is a 20 pin connector to mate
 with a 2nd board I designed, identical in shape and size to the main
 module, but only has the 2 IN-18 socket footprints and the corresponding
 anode drivers. This slave module also has the 20 pin connector at far end.

 The result is that a clock can be configured using 1, 2, or 3 modules. If
 someone wanted, they could build a 2 digit clock (not sure why you would do
 that) or a 4 digit (my preference) or a 6 digit clock.

 I will be including provisions for under-tube LED lighting, even though I
 dislike it, and colons, which I do like. The colons will be controllable. I
 prefer a flashing colon on 4 digit clocks, and a static colon on 6 digit
 clocks.

 Since it's Arduino driven, the end user can do whatever he/she likes as
 far as timekeeping, (GPS, etc) features, etc. I will be producing a number
 of boards excess to my needs, so let me know if you are interested. I will
 NOT be supporting software that will be up to you. The board is
 designed such that the open-source software should work without
 modification, or with very little, for basic 4 or 6 digit clock
 functionality.

 The boards will have both thru-hole and surface mount parts. You will need
 to be able to solder your own SMT components.

 Any interest? As far as pricing, I'm only going to be looking to recover
 my blank board costs.

 I know there's a plethora of IN-18 kits out there -- please tell me about
 your favorite. I've got tubes and I want to build my own case this time. If
 you're selling kits and want to blow your own horn I'm good with that as
 well. I'd design my own and have done so in the past, but I know there are
 already many choices.

 I can do SMT work no problem, would like a highly featured clock with GPS
 sync capability, but it should be able to operate stand-alone as well.

 Would consider either 4 or 6 tube, 6 preferred. LED lighting is
 unnecessary, colons are necessary.

 Arduino based would be nice so I can play with the code a little easier,
 PIC ok as far as that goes too.

 Compact form factor is a plus, as is low cost.

 Please don't just throw out links I can find those. I'd rather hear
 about your actual experience with the kit.

 Thanks in advance,

 Terry

Re: [neonixie-l] Re: New Nixie watch with custom made tube - close to prototype

[Dylan Distasio]

This looks great.  Any idea on when they might be available and the
pricing?  It will be quite an accomplishment to mass produce a new nixie.
Thank for your comments, guys!

Dalibor and I are working on our project separately, but it happened that
we started at the same time. Dalibor went for making big tubes while I
focused on minimizing the tube size so it could be suitable for a watch.
But we have consulted each other along the way.

@Dekatron42, for now this arrangement was the only possible. There are no 4
tubes in this watch, but 4 digits in one tube, multiplexed. I have another
project in mind with 4 digits in one line, but I'll work on that when I
finish this first.

 Looks great! So you  Dalibor produced a new type of nixie which has all
 the 4 digits included in a single glass enclosure? That's quite an
 achievement, really impressive! Definitely a Kickstarter-worthy project :)
 And of course there are some other nixie watches out there, and while cool,
 they always looked a bit too bulky to me (but that's just me). This one
 looks a lot more clean, well done.

 Newly produced tubes?

 Interesting!

 Maybe I have put it wrong, what I wanted to say is that it will be first
 watch with newly produced tubes, not NOS ones.

 I didn't want to undermine the success of already produced nixie
 watches...

 Vladimir, why would you call it the first true nixie tube watch? Several
 members here have made such watches, at least one member produced hundreds
 of them in production.

 Hi All,

 I am working on a very fun project for about 3 years - a 4-digit nixie
 tube that can fit on a watch. I know this will be very interesting to you
 guys so after long time I am posting it here, since I am close to
 production.

 I have posted it on a watchuseek forum:
 http://forums.watchuseek.com/f77/first-true-nixie-watch-
 concept-1482449.html

 Check it out, you will see a 3D model of the watch with some more
 details.

 The nixie tube inside will be assembled soon - in a couple of weeks,
 and I'll post some photos what I finish it.

 I must mention Dalibor Farny here because he helped me a lot during my
 work. Thanks Dalibor!

 Vladimir
