Well, who else ended up here from Technology Connections link?
Me
was already subscribed but I'm back now from there
I think these were by the Atomic Energy Commission for nuclear weapons testing in the Nevada Desert during the cold war. The refresh rate of the screen display was fast enough measure time coding information perfectly, they would be referenced on film recordings of bomb tests. I cant remember if it was used for timing of the explosions or if it was just for time tracking of the film.
You may be the answer to the video, but your comment is buried in a pile of other comments. Fran may never see this.
Or reverse engineering from "other crafts" or systems that had high voltage power subsystems to augment the "other super high voltage electro systems" used for primary propulsion. Maybe?
Also they could withstand a helluva EMP. ?
Clark Magnuson not to worry, the power of RUclips prevails and it's now a top comment!
@@mycosys That was my first impression, this was specialized equipment that was made for a specific purpose. I would say military application would be the most common sense application. I would also consider the Space Program or rocket research.
@@wHiTeHaT44 She programmed the counter to count up; you can program the tube to count down as well. And some people have proposed this might have been used for timelapse or a time counter for video.
If it's rare and you're looking for one, is it called Finding Nimo?
OMG ^^
Groan! :-D
You are killing me! 😂
Smart ass! 😏🤣
Put that as the video title with some Nemo / nimo clickbait thumbnail and you got yourself 4-10x views
9 out of 10 early 70's super-villains prefer NIMO tubes for their doomsday machine countdown-o-graphs
readmedottext or nixie tubes
the other 1 out of 10 use nixies
When I first see it in action: "That looks way better than a NIXIE. I wonder why they never caught on?"
Then I hear "1750 VDC" "Oh...thats why."
@1968garfield remember that commercial solar panels were also hot new tec around the same time as nimo so they were thinking business would pay a one time premium fee then have free electricity and batteries were not an issue because the tubes only needed to work 9 to 5.
If you listen the entire video, she explains that they were not available until after NIXIE tubes were already becoming obsolete. Along with other factors, like requiring a more complicated power supply.
same here....... 1750V AC..... ok sure
but DC...holy FUCK!
@@mycosys sure it may be microwatts (which means LOW amps)..... but its still 1750 D.C!
stress on the DC part!
@@kainhall dont really get whats so magical about dc to you
1970 - Let's see how long we can make it last.
2000 - Let's see how quickly we can make it deteriorate.
capitalism at it's finest
@@niabiii we as a nation of consumers drove this process. In many cases we don't let a product die before we replace it with the latest and greatest version of said thing. Why would a company produce a car that lasts 50+ years when many get a new vehicle every 10 years. They just give the people what they ask for.
@@NavyVet4955 you have it completely backwards, no one wants to replace their 20k $$$ car with a new one ona whim, do you understand how much money this is for people?
@@johhnyknoxville3948 clearly until the recent economic crash people were often replacing their cars, you simply need to use those fingers and that device in your hand to find the info.
The intelligence of people like Fran who can not only understand but build things like this blows my mind.
Really? Its not rocket surgery...
It is very cool though, so Yay Fran.

this has nothing to do with intelligence...passion is all you need (and a nimo-tube of course)
Tom Treacy Rocket surgery?
@@newjargon1697 it's something smart people say
It's really cool watching you mess with things from my Dad's era onward, so I'm really glad I found this channel! He was an engineer from back when you didn't need an expensive degree, and worked with airport radar equipment back in the beginning of that technology. He always said if he did have that degree on his wall, he would be in the history books on radar technology - for airports, at least.
Later, after some issues in his life, he moved to the less stressful radio and TV repair business. From 2-way radio to home entertainment radios, and about anything with a tube or 50 inside it, he could fix it. Anyway, your channel brings back memories of me helping him solder stuff on his workbench in his spare time. ❤️ I really appreciate it!

I spent 7 years in the NAVY on submarines SSBN 619 and ssbn 634 all built in the late 60s we had those tubes in our MK 19 GYRO and our 400 hz transfer system. The MK 19 gyro had over 200 tubes . I was trained in all tube electronics still have the books When a MK 19 gyro goes down and you think it has a tube you have to replace all of them with a tube pack that was tested 5 times before sending them out The tube we think has to be tested with a tube tester as we have to test all of them we write down any failures and the submarine carries 2 sets . My subs went out 70 days or more . Oh if you have a failure again you hope the 2 tubes that was bad and now no spare it sucked I still have a few laying around . 1 of the subs went into drydock for upgrades and they were throwing them away I have all the schematics for them. I would have stayed in for 30 but I got hurt bad that made me lose control of my legs
Thank you for sharing..
@ ncrdisabled Submarine vet
I maintained the MK 19 gyro for years. I call bullshit.
1: It did not have over 200 tubes.
2: Once you have tested a tube, why on earth would you subject it to 4 more tests?
3: The gyro comes with a very comprehensive manual, which generally allows you to isolate faults quickly.
4:The servo amplifiers were designed with double triodes, each of which was capable of maintaining the performance of the amplifier; if one failed, you changed it, without requiring that the entire system be shut down.
5: Submarines are not noted for their space; You do not have the capacity to carry an abundance of spares. Relying on the skill of your technical people is a far better policy.
6: I was on a 18 month deployment, and I had maybe 5 'maintainers alarms', and I think 2 'gyro alarms', neither needing the system to be shut down - in fact, the most serious snag I had was a failure of the cooling fan in the control cabinet.
7: This device ( NIMO tube) was not a part of the control system, and I cannot imagine what purpose it would serve.
8: I don't believe you have any technical knowledge of the Mk 19. You were just a toolbox carrier.
Probably used a TV-7A/U tube tester.
Do you still have the tubes? I might be interested in purchasing if available.
By 79 (SSN 684) we had re-programmable buttons (called PROs) on the BQQ-5 suite. Push the button and the text on it changed. Way cool.
A bunch of tech-heads are now furiously scouring the internet for one of these.
I'm about to make a mint!
While all you peasants are furiously bidding on eBay auctions, *I'm* learning glassblowing, to make one of these bastards.
Anneliese o'callaghan I'm going to build a car, I just need to make the shell right ? Lol.
Inner parts for vacuum tubes are easy. Anyone with even minimal metalworking experience and equipment could knock out the inner components of one of these.
A true Dutch master :)
This tube looks like it came straight out of Fallout 4. Also I just learned you are Frantone ! That's cool
the power armor internal displays use nixie tubes
looks like the number 2 on the fallout 2 cover
Trippy! You're an absolute fountain of knowledge on this quirky, rare tube that just barely existed. Thanks for this sweet venture into our 1960's! :)
Cooler than cool bananas!
EEVblog hey. It’s Dave!
Dave must be top comment! Help Dave on top!

Look at Dave, in like Flynn. I bet he'd love to give this more than a sniff test.
Dave's clearly a bottom.
I spent a fair few hours glancing at these when I was in the military. They were a part of a telemetry display used in missile testing.
5:28 The “near zero RFI generation” caught my eye. What if there was some specialized, classified military application where these were ideal?
Lawrence D’Oliveiro - It's not a big mystery. Listening in on very weak radio signals is a bread-and-butter intelligence operation. You would want the equipment you used for that purpose to generate very little self-interference.
I'm sure these saw more military use than people would think.
I graduated from high school in 1969. Your video brought back memories of the various electronic projects that I was working on then. I used electronics in my three-year-long research project that I completed during high school that won a prize at the 1969 International Science Fair in Fort Worth, Texas. (I studied the influence of electricity on the growth of the sensitive plant, Mimosa pudica.) That science project was one of the factors that worked in my favor in being admitted to Harvey Mudd College in Claremont, CA. I continued with various electronic projects during my undergraduate and graduate school years. Now, I'm a general class amateur radio operator, KE5HXX.
FRAN! YOU SHOULD HAVE NAMED THIS VIDEO:
*FINDING NIMO*
;~)°
K. K. K. K. Good joke
I see what you did there 😂
AccAccAccAccAcc
Thank You, Gustavo & Kevin!
FWIW: I have always been one of those "never forgets a face" types.
In the last decade or two, I began to realize my memory works by 'association'. And it was NOT just faces, but *anything* I see or read - and to a lesser extent hear, smell, or taste - can sometimes brings up an IMMEDIATE memory of some kind. Reading "NIMO" *immediately* reminded me of the title of the movie "FINDING NEMO".
NOW, if I could just *recall everything else* in my memory *when I needed it* ...《grin》
Ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha ha !!!!! ...Good one.
That is FREAKING AWESOME!!!!!!!!!!!!!!!! ............you rock Fran!!!
... and your bench is nicely organized like mine: last used materials and tools are used to push previously used tools and materials away from the central work area lolol
thats normal :) Also here lol
I have seen a teenage daughter's bedroom tidier than this.
Einstein was unorganized to. Great minds don’t worry about making things look good they just want to create. That’s my excuse for being a slob.
One of the best obscure electronics videos I've seen to date! Thanks for showing me something that I never knew existed. I'm going to set aside some time to binge watch the whole series.
You are awesome for bringing this thing back to life and sharing it with all of us! This is the first video of yours that I've seen btw. Thanks!
after 2 years am also watching her for 1st time
Ended up here after an AvE video and am very pleased, you have another subscriber
That was my reaction too -- it's like AvE for wireheads.
You will be seriously disappointed.
I love how you see some videos and the freaking soldering iron looks untouched. And then you have labs of people that do things. Like hers! I love it.
old vid, but I just thought why the anode is on that button. It's probably for future plans on making these things entirely socketed, so you can just plug them in and out.
they are fucking rare! she has one, in numbers 1, of them, because she was fortunate! did you even listen to her?
@@hansmuller4338 did you even read his comment? lmao
I just love the occasional EEVBlog multimeter in your videos, it's like a little treasure hunt to find it in the different shots to me :D Also, great video als always! Gotta thank the patreons myself for making this possible, otherwise I would miss your videos a lot!
Can't believe I only just found your channel.
Subbed!
People like Fran get me so motivated
I believe general electric was developing a miniature version of this. My grandfather Herold walker was an engineer for them for 40 years. He had patents that were property of ge for things such as a machine he invented to test light bulbs for correct gasses content with polarized light to spot defective ones quickly. Absolutely wonderful video!
Inflation calculator says that $29.95 in 1969 is $201 in 2017. Whoa-yeah.
So basically a 4 digit clock would cost about half as much as a new 1969 VW Beetle
At the time, I recall being told that transistors were a passing fad. Never make any power, too noisy, fragile, low frequency only ... which was kind of true for a CK722 . 1700 volts wasn't all that much considering 450 volts was a fairly common plate voltage and I lost count of how many times I took 14 Kv shocks when I was converting a TV to a scope ( ok I was 12 and a the anode connection was behind the chassis ) but I can see the established tube engineers thinking this was the way to go.
..I remember when you could (as a hobbyist) only get 2 types of transistors...CK722 and 2N107......and high-voltage rectifier tubes were being replace by Silicon Rectifiers..!
I built a radio in 1958 that used a silicon rectifier...fit right into a fuse socket...plans from Popular Electronics....the radio still used a couple tubes for everything else...no transistors....
Doug Ankrum , recall adding a resistor to make the silicon diodes a closer match to a 5U4.
sporadic -Z , I still have a working NeHe gas laser , speaking of a 2.5 Kv power supply.
On this side of the Pond, Mullard ruled, and we had the OC71, with a cutoff frequency of 350kHz, and a noise figure which was unbelievable. Scrape the paint off and you had a photosensitive device which was quite useful. The OC72 was its 'power output stage' counterpart, usually used in push-pull, giving around 200mW of audio, if you used heatsinks. Mullard later developed RF transistors with internal screens, so four leads out of the bottom of the aluminium can. Top it off with the OA81 diode as a detector, and you could build a radio receiver which could run quite happily on a single dry cell at 1.5 Volts. Later on, we had the OC200 and OC201 transistors which were symmetrical, in that you could even connect them the wrong way around (Collector to positive instead of to negative) and they would still work. All devices were Germanium, and mostly point contact, not Silicon wafer, so everything had to be properly biased, in an attempt to reduce thermal drift, which plagued Germanium semiconductors. You could destroy them with soldering iron heat in around ten seconds, too. The ubiquity of PNP transistors meant that ground was almost always positive. Happy days.
Did the photo transistor trick too, and later pried the metal off a ceramic case 4164 to make a crude imaging element. Worked but they had a curved epoxy layer over the silicon so a bit distorted and really was 2 32K bit elements with a bar between. Tube days, a 12 year old armed with the warning not to push a rectifier over 25 Kv is of course going to play with X rays too :P . I think I recall seeing Nimo tubes on a Dr Who episode, wonder if it was the one filmed at a working nuclear power plant.
You are amazing! Thanks so much for this in-depth view! I didn't understand all (most) of it, but it makes me excited to learn new things. Well done! :-)
Loved this video! So glad i found your channel!
Another unique an amazing video, Fran! Keep them coming! Thank you! :-)
Reminds me of the old "Magic Eye" tuning aids on receivers from the early 1960's.
Julia Marshall I loved those. My father had an old Webcor reel to reel tape recorder that had one to set the recording level. I remember talking in to the microphone and watching the little phosphor eye "talking" with me. Very cool to me back in the day! I'd love to make a project with one to relive those times.
Fireship1 I have that webcor Chacago also
Hah! I was just about to say the same thing.
I had one of those tubes. I think my uncle gave it to me. I was too young at the time to appreciate it. Don't know what happened to it.
Magic eyes predate the 60s by several decades.
THANK YOU for sharing this lil' tube in action.
It is now my FAVORITE thing ever!!!
The best feeling an inventor/innovator can have is the “it works...” feeling. And let me tell you, no matter how small the object or machinery that feeling is the most satisfying thing when it comes to making something new.
Who needs a fancy edited intro when you have a little diddy like that? "It's Fraaaaan (again) in the laaaaab. FRAAN LAAB!"
agreed. too many pages have stupid intros. just get on with it already.
That part reminded me of Linda from 'Bob's Burgers', which is a compliment because every character on that show is hilarious
frans the best.
Isn't she on mfc?
I love this lady
I really liked this video. I really liked the display and how you've kept a tiny bit of elecro-tech history for us, and I like your engineering a LOT. Bravo
How have I not found your channel before?!? Love the controlled chaos of your lab.
I knew about nimo tubes,but had never seen one,let alone one working. Thanks!
Entertaining and informative. Liked and subbed.
You're an inspiration to all pedal builders! Great channel and work :)
4:00 probably used in the military then. if something is produced and cant find any civilian application whether industrial or not, you can bet its military.
This might be a bad memory, but back in the 80's my dad was a tchnisian in an oil refinery. P{art of his job was running the control room. I remember nimo tubes (I didn't know what they were called then) and I thought they were pretty cool compared to the nixi tubes I'd seen in other places.
You drunk friend?
Thank you for the video, thats so awsome that you put this together!! And it looks so old school bomb shelter style. You rock!
Sometimes when I'm really high I'll see Fran
I don't think Fran will be pleased to see a swarm of bees heading towards her from a really high altitude.

Yes, the Nimo--sort of a scaled-down numeric-only "baby brother" of the Charactron. The Charactron (developed by Convair in 1954, IIRC) was another similar, but much more advanced CRT tube which also sports an electron bean stencil plate to shape the electron beam to form the numbers displayed much like a Nimo. Although the Charactron could also do letters and symbols, and have the character positioned anywhere on the screen via a set of secondary deflection coils. The Charactron could do vector-traced graphics as well using said secondary deflection, and a special "center dot" character in the stencil, where the resulting formed narrow beam could be deflected and steered to write vector graphics to the Charactron's raster, like a traditional vector scanned CRT.
The Stromberg-Carlson SC4020 computer film recorder/plotter from the 1960s used a smaller 5" Charactron as the heart of it's workings, and the SAGE radar terminals used by the US Air Force also employed a larger-sized 19" Charactron for their displays. Bell Labs used a 4020 to create some of the very first computer animation to film in the mid-60s using their Fortran-derived "BEFLIX" graphics language. And IINM, NASA also used a 4020 to print out the first digital images of Mars from the Mariner 4 probe in 1965. Wikipedia even has an article about the Charactron: en.wikipedia.org/wiki/Charactron
Fran, if you could find an old Charactron to demonstrate in one of your videos, I'd be delighted!!!!
Ryan Schweitzer. Yes, I heard or read this years ago. Some say it was used to play zee first video game of Space War.
Bell Labs used vector graphics in 1963 to create a animated short film to portray the orbiting of a satellite around zee Earth
I used to work for IEE in Van Nuys about 15 years ago, they were going into commercial point of sale displays but their history was ALL military displays. I do remember seeing one of these on the desk of an engineer who had been there for 37 years. He explained it as a CRT nixie tube (for simplification) while telling me of the military uses it had performed. They also refurbished the displays back in the day.
They are still around. ieeinc.com/
If I worked there I would tell everyone I worked at IEEEEEEEEEEEEE!!!!!!!! and would pronounce it :)
I downloaded the archived data sheet that Fran referencesd I'm amazed that this firm is still at the address shown on their 1969 data sheet. Their website shows that they continue to innovate in display design.
@@erickschumacher1294 I took the office of an older guy who had as a screen saver "who is john galt" and then next office over was a guy named Mike who invented CCFL . .my supervisor was a tall redheaded woman.
@@erickschumacher1294 were you there when they decided to "ruggedize" the 42" plasma screens, that was 1997. I was hired during a period that felt like the company was conflicted between the status quo and adopting new ideas. Status quo actually adopted new ideas but then didn't recognize itself. Confusing idea, yes it was. it was like a sinking boat tried to put the sky below it to stay atop the water.
What an interesting piece of technology. I've been interested in Nixie tubes for a while, but this is a whole new level! Also, I'm happy that Fran is not a spastic youtube presenter with jump cuts like most of youtube presenters. Thanks for making this video!
Thank you for this, Fran. Very interesting. I feel as though I've seen these in older sci-fi or nuclear war type movies. Almost always a countdown display.
i was digging with Nixie, Glad this came up!! love your content also your way of talking ^_^
Fran, I have some of these tubes (somewhere!) - no they are NOT NIXIE tubes! Mine have a hash and some other non numeric characters and came from demonstration display that was used at the Mullard expo in London (it wasn't only Mullard equipment but an expo of new inventions). Prince Philip attended and I met him at the time. I too obtained them to play with but unlike you never managed to do the job properly so they are in the attic, or the shed, or the outhouse, or..... Do you want one or have you exhausted your interest? I am in England so they'd have to travel well. Rob.
I would love one to play with!
I think getting some to her would be awesome cause she could make a calculator for it. I would love to see it
They said that the tubes were not numerical...so no calculator
I'm also in England Rob, these tubes are pretty interesting. If you are looking to get rid of one or two, I'd love to have one :) I really would
If possible I’d love to make a clock out of some of these.
I found this channel seeing some vintage music equipment videos, which were great, and now I'm finding out Fran has videos on all sorts of super interesting subjects. Great stuff!
You ROCK Fran! Love your style, you are such an engaging speaker. God bless.
And 40 years later, a company called Vu1 got the equally wacky idea to use a miniature CRT as a light bulb -- the ESL (Electron Stimulated Luminescence) light bulb. Needless to say it was an idea that didn't catch on.
Well it's settled then - get three more of these tubes and two Vu1's for the : for a clock. Easy!
That was my idea when I was 11 or 12! Wondered if it could be morefficienthan a fluorescentube.
After the haul video you're a lot closer to that clock project ;-)
Fran Blanche any progress here?
Whoa, cool! Can you tell me anything more about it? Was it powered directly from the AC socket, or did it need its own solid state power supply - - or a combo of both?
I mean what kind of ac/dc adaptor goes with it, or inside it(its base)?
Hey! Just found out your channel
Hi Fran! Thanks for the content. You're helping me sleep. My mind races at night, so your interesting yet calm videos help me settle down and relax.
Thanks for this, Fran..truly excellent presentation and content. I suppose you have a rockin’ set of Nixie tubes…
Someone broke one of these to expose the matrice, it's pretty interesting as it has the numbers laid on it. I wonder if the round version (as the broken one is rectangle) is displayed in a carousel style or different.
I think that with the technology we have today in tubes (the slight, but considerable advances in power consumption) we could make more of these. Even as a DIY level, i can see this happening. OF COURSE, the price would be high, but hey, we're making Nixie tubes, again, after so long. One of these, isn't much more complicated.
Well, it's basically a a slightly more complex variant of a CRT display. (relatively speaking - I imagine the kind of colour SVGA tubes used in the late 90's might be a touch more difficult. Or not. Who knows?)
It's an interesting thought that you could make such things as a hobby.
Though CRT's were pretty dangerous to develop. (apparently a lot of the earliest designs produced large amounts of radiation. I forget what type. X-rays I believe. - not the healthiest thing to be exposed to.)
Still, can't be as bad as semiconductor manufacturing.
And I know for a fact someone did that at hobby scale - quite an ordeal just to make your own transistors...
(The problem with semiconductors is that commercial manufacturing quickly moved towards using chemicals that are amongst the most deadly you could think of - odourless gases that can kill you if you inhale them. Fun.)
Some of these things are definitely doable, but at a hobby scale it carries a lot of potential hidden risks for the unwary...
I'd love to see someone do it though. XD
LEDs and a light mask are an interesting idea. Ultraviolet LEDs could make the phosphor coating glow in the same way the electron gun did. You'd need lenses to focus the UV LEDs, though; that would add a bit of complexity.
Well now at least, someone in China will be tooling up to flood the market with these.. they are just too cool not to be wanted by every tech head on the planet.
But it would be safer.
It was already done, the tech behind it is known, you could even get a broken one for reverse engineering if a teenager can make a breeder reactor in his garage I can't see why an electric engineer wouldn't be able to make one of these. I think that the issue might be with people not wanting it. Why waste time bringing some old crap back if few people will buy it.
Making a microprocessor is magic though.
What a neat bit of electronics history. Really cool find. Really awesome.
Awesome cool vintage tech! Thanks for this video presentation.
So neat , thanks for all your hard work Fran , love your stuff ....
Thank you for showing the operation of the rarest display on Earth!
From a technology course I took more than 40 years ago, I believe those Nimo tubes were used on some continous-tuning HF-VHF-UHF radio receiver, which required a frequency display that generated no internal interferences. The Nimo requires the same complex bias of an oscilloscope tube, but that is dwarfed by the complexity and cost of such all-frequencies tube radios for special customers. I want to emphasise that I heard in a teaching course about the tube, but I have never seen it. My hands-on experience is limited to devices like the EM80.
Thanks for the video - and for the incredible patience needed to put together all the power supplies, the bias circuitry and the drive logic...
Makes me think of the “green eye” tuning tunes of old tube radios.
Me too I don't see why they could not have used one of those in a different way and not had to use 1700 volts
@@ronalddaub5049 the reason why it takes soo much voltage to drive the tube is due to the heater inside the tube, a NIMO tube is basically a micro CRT
Got to say working in Electronics for over 45 years and never seen a Nimo tube, but it looks cool.
First time I've ever seen this channel I subscribed instantly I love you Fran keep it going!!!
Wow, I just discovered your channel, great stuff, you are just adorable!
You are so cool.. I envy your skill and knowledge.
66 year old female here...
So you have no knowledge about anything?
Sagans Run Don’t envy, go and learn new things on-line!
My Mom learned to drive at age 60. 24 years later, she is itching to get back in her car again but the lockdown means that she has to stay home and I get her groceries from the store. She used a Windows PC at work but in January 2018, she got an iMac, an iPad and she has an iPhone and handles them like a boss to make crafts and cards for a local thrift store.
When I worked in a school, pupils would always say things were “impossible”. So we moved around some of the letters to read “I’m possible” - so something small and move on to more complicated things later. Good luck!
Made me smile seeing this pop back up in my suggestions again!
This is the first of your films I watched and immediately SUB. You did a great job. Keep it up.
I love Fran!! If Fran Blanche and Peter Barakan hosted a show together with Ben Minnotte as MC, we would surely know world peace.
Congratulations! Think how many people are missing this because they don't know how cool you are! LOL Your "do it yourself mounting" for the NIMO is not only ingenious, but highly functional!
Better let them in what a "compactron" is.
Thanks for a great video Fran! I started working for Hewlett-Packard on January 26th of 1973 at the tender age of 19 as a trainee tech repairing the HP35 calculators and saw a lot of technology there over the 22 years that I worked for them and I had never seen or even heard of the NIMO tube until I saw your video today, so thanks for helping to enlighten an old technician and remind me that I don't know everything (which actually isn't to hard ;D). When you showed the One Plane display towards the end of the video (which I had seen and even played with at a friend's home years ago) I noticed that IEE was based in North Hollywood which is where we live and now I'm intrigued to see if I can find there old facility. Thanks again for all the great tech info.
Easiest way in is from Kester & Saticoy go north on Kester and follow it through the hood ahead. @ Keswick you should be able to seee their shipping bldg to the left. Take Keswick 1 block west to Lemona and you have found what remains of IEE. All the brick buildings you see on your tour used to be IEE or related. About half of their buildings are still theirs. My office was in a building that had been there from the beginning. Now it is a marble/granite showroom. AARRRRGH!! what a waste
BTW, technically it is located in Van Nuys
Amazing. Glad i found your channel
Not sure why I was suggested this video, especially after being over 1 year old. What's more puzzling is why I'm still watching it 15 min in...
@Pool Bal there's a moron in every comment section. You are ours.
your work bench is just as tidy as mine,lol
Amazing video, thank you!
I enjoyed watching this. Thanks for the info.. keep up the awesome work.
Just when I thought you cannot possibly come up with an even more interesting topic.
Can't help thinking I've seen these in 70s British sci-fi TV shows. Perhaps the BBC was their only customer?
i thought for sure i have seen them in the old Moonbase 3 series or more likely the great UFO tv show, seems to me Shado HG was full of great electronic gizmos,!
maybe Dr Who.....
Nicely presented, thanks Fran!
just got alerted by RUclips of this video. Very very amazing. Thanks for the clip!
Looking at the projection displays, I found that when I was working for a defence equipment manufacturer for many years, there would be relay logic units that would come in for servicing or refurb that used a very similar 3 x 4 miniature units. They were used for logic/status indication of controlled equipment and used T1 3/4 28 Volt lamps with coloured silicone caps and printed legend films slotted behind 12 miniature lenses and projected onto a diffused glass screen. They were not made by IEE though, I forget at the moment who made them, but I can always remember that the spring loaded electrical connector that mated with the lamp's 'pip' were nearly always problematic due to the amount of heat from the lamps.
Thanks Fran!!
Wow. That’s Soooo cool. Nice job, and I salute you for actually taking the plunge risking it by building everything to run it!
I love your energy! And I learn so much from you on top of it. Bonus!
It pleases me the retro look that the Nimo has. It should be funny as well to perform experiments with other kind of display tubes of 1950/60s like typotron or the charactron , even rarer than Nimo.
Great video Fran. I had never heard of the nimo tube. Maybe they all went down with the Nautilus :)
Except no Nautilus "went down".
Very cool video! Terrific project and description, very well done!
Such things used to be fairly common to come across at tech shows but yeah very rare working now!
Thanks for a great video and thorough explanation Fran !
It's retro and cool looking! They would make an awesome clock! I see you need a beefy power supply to run it.
Yea very expensive clock. I will get an app for that.
Your cool. I need more quality content such as this.
Absolutely beautiful. Fantastic build!
Just found your channel and subscribed straight away. Fantastic content delivered really well. Congratulations. 👍🏻
Looks like something from the movie Brazil.
Never heard of these. In the 60s I worked at a NASA satellite tracking station that had Nixie clocks in many of the racks - just loved them!
Ashley Booth Build one! I did last year just for kicks. I made a plexiglass enclosure for it so that stray fingers don't get zapped! I love the glow it produces at night in my living room. There are lots of kits online if you don't want to cobble up your own parts and design a board.
Fireship1 I have built one and now building an Elector GPS locked one!
Found you last Wednesday... i so love your channel!!!
Excellent work, keep it up
Visually reminds me of the Magic Eye tubes from the radios from the 30s and 40s. But definitely a strange build. Seems like the neon digital tubes would have been the easiest way to go in those days
Given their high operating voltage, would they have been immune to an EMP perhaps?
Amazing design ! What a treasure you got Fran !!! Nice project !
Thanks for making it work, it's a great video on account of your hard work.
