@@tim.honiss Always the biggest problem with Nixie stuff, and it will only continue as original nixie tubes get rarer and rarer. There's at least one guy making new tubes by hand in a few different styles, but they're ludicrously expensive. I don't know of any company that is making them as a niche product in any kind of semi-automated fashion. By the time finally get my arse in gear to pursue a Nixie project they'll all be priced out of the market for me. :(
@@sixstringedthing I believe Dalibor Farny makes new tubes, if I'm not mixing them up with someone else. But still small batches and lots of effort as well as custom equipment, so I wouldn't say they're cheaper than alternatives.
You remind me of the Musical Fire Table, made by some danish guys. (/user/Fysikshow) was featured by Veritasium (/watch?v=2awbKQ2DLRE). Not really a fireplace as in burning logs but its fire responding to sound waves making patterns atleast. :D
Lew from unboxing therapy actually did a video in something like what you described. It's not a fire place but a Bluetooth speaker with fire that responds to the music like a graphic equalizer.
I was thinking I'd love to see a 10 or 12 band Nixielyzer, but yeah a 31 band version would be sweet. perhaps an rs232 plug and socket on the ends to daisy-chain the modules and automatically change the bands, 5 kits = 30 bands.
Thanks for the wonderful video Matt, your “less is more” front cover really improves it, trouble is as you said, it’s something that no one needs one of, so I ordered two of them :)
Built my own version of this about a month ago using IN-13 tubes. I could only afford to do 2 tubes but even with only 2 you really can’t convey just how cool they look over video.
i did it 2 tubes IN-9 , having more than two tubes means you need band pass filters that are exponentially messy, also separated a lot the two frequencies to have the maximum diversity between the two bands (worthed), used a pair of CRT color electron gun transistors (most types are good and less blunt than like MJE13003)
Nixies are high speed. I've seen a Nixie clock that fades between numbers. Any unsuspecting viewer would assume it's fading because it's old and slow. Not so! It's being pulse width modulated at 100Hz+.
At end of 80s - beginning of 90s my father had an idea of building power amplifier with graphical equalizer based on ИН-13, he even got somewhere big heavy case, and two huge transformers. But economic situation in Russia in that time was horrible and there is no money or time for such hobby. As for now we still have most components, and maybe someday we build this amplifier.
I think nixie tubes are how I found your channel, and I know that the spectrum analyzer videos definitely appealed to me, this is the perfect marriage of them with a sprinkling of "I have no use for this, but I NEED it" to top it off. I mean, I do already have several nixie items already, AND my home DAW/mixing setup COULD use some fancy flashing lights... I think that counts as a business expense, right?
I think I speak for many people when I say: *COOOOOOOL MAAAAAAAAAN.* Neat kit, will definitely be investigating the kickstarter. Thanks for bringing it to our attention!
I was thinking this while watching, almost feel like the "previous version" that was showed later on was a better design, at least on that specific detail
@@F0nkyNinja that's true, and it's not like it's a scientific measuring instrument. But looking at the other one on the site, I think it appeals to me more haha
The comment that "this should not be your first electronic assembly project" makes me wonder if there could be a video that could provide some fun introductory kit recommendations. Or maybe a 'these are the basic tools that come in handy for most projects' video Great videos by the way!
The front cover is great as it is, in my opinion. It gives a sense of complexity and sophistication looking at it. Instead of a dull impresion understanding everything at first glimpse.
agreed, narrow base with very tall, thin glass tubes poking out the top, with loads of RCA and headphone cables coming out of the bottom, it looks almost guaranteed to get flipped over and smashed in no time at all.
One of the cool things about DIY kits is that one generally feels less guilty about customising/modifying them compared to a pre-built product. Could be an interesting project to make an add-on protective screen/guard out of wire mesh, or some similar idea.
For most of the target consumers of this product, yes, it is. However, Techmoan values the cool factor more than the assembly, which -- if one isn't comfortable with soldering -- is a big hassle.
I built the in-8-2 nixie tube clock while drinking lots of whiskey and it worked first time, they are simple to put together and instructions are easy to follow. You need to be careful that the switching supply in either the unit itself or wall wart doesn't inject annoying whine hissing or hum into your audio , especially since you are plugging it into line level equipment, you will notice this more on power amps that have the gain turned all the way up and that are fed from an head unit you are using to adjust the volume, i would use a ground loop isolator to isolate it. It would be nice to get a wood and polished brass base version of these kits, would look far nicer, the aluminum and text all over the place makes it look cheap. The plastic base on the clocks look ok with the RGB leds.
Nixie tubes are fab. As a kid I had a huge (as in size of a briefcase) desktop calculator from early to mid 70’s. It had a display of ten Nixie tubes and looked fab even if it did need a small power station to supply it.
"No servicing parts inside". You guys have interpreted this all wrong. If you're servicing parts, do it outside. The flux smoke will stink up your house!
Another fine video Techmoan, I ordered one assembled and look forward to getting it. The nixie tube watch you featured a while back was one of the best things I ever bought even though it was over $600. Keep up the great work my family and I enjoy watching your videos
The design of the circuit is quite elegant. He's managed to make it completely analog, and it appears these tubes work by varying the voltage applied (between 100-140V), but the current is low enough that relatively small high voltage switching transistors. The MPSA42s on the outputs of the LM358 dual operational amplifier chips are switching high voltage DC to the IN-9 tubes. The use of a photo flash capacitor in the high voltage DC power supply is innovative and saves space. I also like that he has socketed the op-amps - this means that if you choose, you can swap them out with higher quality chips that have the same pinout.
This actually looks pretty easy to put together compared to most kits these days, many of which are all tiny SMD components. This kit uses all old-school through-hole components except for a couple SMDs that are in extra large packages.
@@z097dsa Well your English is better than my German (despite my having worked in Austria for a time). Being a kit though, you could argue that this phrase is not required anyway.
IN-9/IN-13 VU meters and spectrum analyzers. A classic project really. Let's see how Mr.Nixie does it. I see... A set of audio summing amplifiers combining the inputs and convert stereo to mono. Then the signal goes through a Compressor before getting fed to a 6-channel Band-pass filter that is designed for Spectrum visualization. The output being done via a set of Op-amp compensated Constant-Current-Sinks. 2x NE555 timers handle High-voltage generation and power-cycling the tubes. The cycling is a clever trick to keep the IN-9 behaving well enough. A very solid design. My own uses a ARM with Digital Signal Processor that handles filtering and generating outputs. Using a very high-speed PWM with low-pass filters to drive the Constant-Current-Sinks. Perk: As many channels as i want. Con: Programming, which some absolutely hate.
It's enjoyable to see there's still business who give you the pleasure to built your gadget, in a world of pre-fab you can throw away in the trash two moinths later. The satisfaction to say I built this, and watch it work, that's the real gift.
I was a Kickstarter contributor for this project, and just received my full kit in the last days of 2019. I hope to add a construction demo video to my TH-cam channel sometime soon. However, a slight correction to THIS video based on my early study of the Nixielyzer schematic.....there is no firmware/software in this product, which surprised and delighted me. It is 100% analog circuit design. Op-Amp based gain and active-filtering for the microphone, and also for the audio mixer stage. 555 timer astable oscillator, with feedback, to drive the high voltage generator circuit. Another 555 timer astable oscillator to reset the Nixies frequently (as mentioned in this video). An analog multi-stage bandpass filter to split the audio signal into the six bands. Six op-amps to control the high voltage drivers for the Nixies. Analog voltage regulation. Seems that Juergen prefers the analog approach to his designs. His Nixie IN-9 thermometer, although it looks nearly identical to the Elektor Labs IN-9 thermometer, is an all-analog design, whereas the Elektor version is based on the Arduino Nano.
My option about the front plate is a bit of both, keep the logo and text that’s current on the front but use the simplified slider text and gray button .
Nice built anyway and great demo, also a compressor or AGC in the input section would lead to a much more pleasant display...and as these IN-9/IN-13 tubes are getting rare, the price will now increase within weeks i think...i bought about 50 some years back when one tube had been around 2bucks...nowadays its more like 10bucks/pcs if you order direct from russia.....these tubes had been developped in former CCCP only produced in the Uljanowsk plant in russia if i remember correctly. New-Sensor (ex "winged C" -> original Svetlana) may still have some
Well you finally did it Techmoan after years of following you. You made me buy a thing (bought via site rather than Kickstart). Came close with some older VU meter delicious HiFi stuff shown in the channel but just could not make it work with my setup.
I just backed Mr. Nixie's project! I got the 32 Euro reward level. It gets me 6 spare tubes and I'll get the finished product after it comes out. It will go great with my Frankenstein's monster home theater that includes some vintage Carver amps along with some small tube amps that drive the tweeters in my main speakers. I use a digital active crossover to split up the signal to my speakers. I will definitely have to go analog once I am happy with the levels. ;) Thanks for the video! :D
I would have a field day soldering all that. A huge part of the enjoyment would be building it. Treat yourself to a good iron such as an Antex and some breadboard and get practicing Mat. I think I had my first soldering iron before I hit my teens.
This is art. I love it. I was kind of cringing at the beginning watching you hold it while talking about it and giving a little shake, and desperatly hoping you werd not going to drop it. Then I though, well that's silly the video would not have been finished if you dropped it.
"no servicing parts inside" ahhhhm, ya mean all those parts that I personally assembled and soldered together in exactly the right place and orientation using a complicated schematic guide? k....
10mintwo Was it spelled like that, because that would be a bug he needs to fix. Other than that, it might be directed at other family members and preassembled buyers.
Presumably a 'cover your ass' warning, so people who don't know how to work with the zappy stay away from the angry lightning pixies that dwell within. And giving more credit that is due, it is not unthinkable for capacitors to hold a charge after the first power-up and change the risks of working with the parts from 'soldering burns' to 'fatal shock', especially if you do a terrible job building it. There's also that thing the other guy mentioned about people other than the builder needing to be warned off. And even if a warning sign has no legal weight in your jurisdiction, making an attempt to prevent harm occuring is usually looked upon favorably if anything goes to court. Labels aren't all that expensive to toss in when you're building hardware, after all.
I would appreciate if the housing had an extended bottom flap to screw into the desk it is on, reducing the chances of it being knocked around by a tugged cable. I wish this design was also implemented more often on small form factor preamps.
If one is money enough, I would definitely like two of these for separate left and right visualization and double the nixie tubes. It is actually very interesting what kinds of nixie tubes exist aside the myriad of different sized and different types of number displaying tubes.
It’s 03:20 in the morning where I live but I’ll be damned if I can’t push off sleep for a while longer to watch this video! Thanks Mat! Love all things Nixie.
Love the simplicity in design, only change, I'm super paranoid and a bit clumsy, I would suggest a dark plexi glass back behind tubes and a clear one in front, to protect tubes and add ease of visibility in brighter light environments, but it is great !
A great idea, well carried out. I am, however, wondering about the fragility of those glass toobs sticking out, without much support or protection. Perhaps a translucent Perspex sheet with a silvered back behind the Nixies, providing some support, protection, and (for some environments), a better display?
Very nicely shot , like the start of a Netflix espionage series but not sure about this . I think in a future version this would be so cool . As always thank you Sir Moan of Techshire .
I think going to a longer stroke slider, such as you'd find on a graphic equalizer, would be epic. Actually, now that I think about it, a graphic EQ with nixie tubes would be pure awesomesauce.
I stopped building electronic kits two years ago because I was going through a major depression and lost any interesst in everything. I am currently recovering and I think this would be a beautiful way to get back to do what I used to like.
Very nice. If I were to get a spectrum analyzer, it would definitely be something like this. I was late to the mini amp video (when the trolls already had taken over the comment section), so I'll write my compliments on the updated outro here instead. Love that you put the glorious three deck cassette player in the updated outro. Much pleased!
I like a lot of your demos on different equipment lease or are they cool I wish I knew some of the music that you played it’s really jazzy and sounds great I’m glad I found your TH-cam channel you bring forth a lot of interesting components.
Very interesting, have a problem with the power switch placement. The chassis is light, very light, each time the switch is pressed, the chassis will move, If the power switch is placed on top of the chassis in front, the unit will stay in place better. It might be best to move the other switches to. This brings to mind of the time when strobe lights and light organs were the thing.
This channel has gotten me interested in nixie tubes. I still haven't gotten anything nixie related, but I still want to, and I'd totally be down to get a kit and put it together myself. Sounds more fun, plus I'm sure it's cheaper.
and now watch this: th-cam.com/video/9g-WU4oZAeI/w-d-xo.html i know i´m spamming, but his work is so amazing over the top, he really needs more attention ;)
Don't really need all that much skill or equipment to put it together. Just lots of patience and some logical thinking, mainly in the order u solder the parts in. Worst thing I see is that SMD IC jobby, but even that doesn't seem to be all that fine-pitched, and can probably be drag soldered just fine with some flux. So don't need a super fine tip and steady hand :) All in all it seems like a lovely kit. Lots of fun to put together, and oh-so-cool when working! Thanks for the video!
Nice idea, but I feel the heavy plastic 'bridge' near the top of the tubes is just too big. I would replace it with a very thin piece of drawn glass hot-melted too the top of the tubes.
Hmmmm. This could work very well as a replacement for the radio dial screen if I need to replace all the innards of a radio furniture. Very intriguing.
I think I prefer the original front panel actually. It isn't sleek, but it really fits the fact that this is a nixie tube device. Those things have a certain aesthetic :)

Absolutely beautiful! I'd love to own one! 👍👍 For Mr. Nixie.
This is art. I love it. I was kind of cringing at the beginning watching you hold it while talking about it and giving a little shake, and desperatly hoping you werd not going to drop it. Then I though, well that's silly the video would not have been finished if you dropped it.
lovely made kit , i wouldn't mind the led green shining through ,
Music at 4:37 is “Shoulder Closures” by Gunnar Olsen for anyone curious!
"no servicing parts inside"
ahhhhm, ya mean all those parts that I personally assembled and soldered together in exactly the right place and orientation using a complicated schematic guide? k....
I noticed that too - it's an odd thing to put on a user constructed item.
Simon Coates probably has some high voltage capacitors.
@@AnonymousUser77254 Isn't it supposed to assemble that thing BEFORE connecting it to the mains socket?
10mintwo Was it spelled like that, because that would be a bug he needs to fix. Other than that, it might be directed at other family members and preassembled buyers.
Presumably a 'cover your ass' warning, so people who don't know how to work with the zappy stay away from the angry lightning pixies that dwell within.
And giving more credit that is due, it is not unthinkable for capacitors to hold a charge after the first power-up and change the risks of working with the parts from 'soldering burns' to 'fatal shock', especially if you do a terrible job building it.
There's also that thing the other guy mentioned about people other than the builder needing to be warned off.
And even if a warning sign has no legal weight in your jurisdiction, making an attempt to prevent harm occuring is usually looked upon favorably if anything goes to court.
Labels aren't all that expensive to toss in when you're building hardware, after all.
I think I have found this years Christmas Present.
For me that is.
I would appreciate if the housing had an extended bottom flap to screw into the desk it is on, reducing the chances of it being knocked around by a tugged cable. I wish this design was also implemented more often on small form factor preamps.
i just love the retro look of the nixie tubes. It would be really nice to design a car dashboard with these particular tubes.
If one is money enough, I would definitely like two of these for separate left and right visualization and double the nixie tubes.
It is actually very interesting what kinds of nixie tubes exist aside the myriad of different sized and different types of number displaying tubes.
That is awesome. Ive always liked spectrum analyzers and this the coolest one ive seen.
Your mechanical repair skills are very good. I can imagine you'd be good at building kits with just a little practice.
It’s 03:20 in the morning where I live but I’ll be damned if I can’t push off sleep for a while longer to watch this video! Thanks Mat! Love all things Nixie.
4am here. Hah!
Mr. Nixie -> Jürgen
Of course his name is Jürgen.
Maybe his name is Nixie Jürgen...?
Von Strangle
Wouldn't it be spelled Jöergen?
VDel he's already dead reep

Love the simplicity in design, only change, I'm super paranoid and a bit clumsy, I would suggest a dark plexi glass back behind tubes and a clear one in front, to protect tubes and add ease of visibility in brighter light environments, but it is great !
Thumbnail wouldn't load, I had no idea what a IN-9 Nixielyzer was but it's a Techmoan video, knew the content would be awesome anyway ha.
It's a beautiful add-on for a hifi setup, spectrum analysers are so cool!
The tubes are just beautiful.
A great idea, well carried out.
I am, however, wondering about the fragility of those glass toobs sticking out, without much support or protection.
Perhaps a translucent Perspex sheet with a silvered back behind the Nixies, providing some support, protection, and (for some environments), a better display?
Very nicely shot , like the start of a Netflix espionage series but not sure about this . I think in a future version this would be so cool . As always thank you Sir Moan of Techshire .
That schematic looks like it was done in Proteus. The marvels of electronics prototyping. 😊
Music at 4:30 is 'Loser' by Stevie Rocker...
I think going to a longer stroke slider, such as you'd find on a graphic equalizer, would be epic.
Actually, now that I think about it, a graphic EQ with nixie tubes would be pure awesomesauce.
I stopped building electronic kits two years ago because I was going through a major depression and lost any interesst in everything. I am currently recovering and I think this would be a beautiful way to get back to do what I used to like.
It is amazing how many of these IN-9s were made in the USSR, that they are still being used!
Very nice. If I were to get a spectrum analyzer, it would definitely be something like this. I was late to the mini amp video (when the trolls already had taken over the comment section), so I'll write my compliments on the updated outro here instead. Love that you put the glorious three deck cassette player in the updated outro. Much pleased!
Yes that definitely earned it’s place in the outro.
Aaaa, Look at Techmoan making real changes in the world! I'm proud of you boy!
The words Nixie Tube spectrum Analyzer has to be the most Techmoan combination ever
Very true, and your comment made me laugh!
How did that not break in shipping?! Amazing.
Another great video... Would love to learn more about the old Gas Driven Radio used in England around the 30s.
Very slick, even for a prototype..
Like watching little jets of flame.
I’ll have nerdy dreams tonight. Drilling holes into my NES and let the tubes light to the sounds would be a fun mod
Neat! Not too expensive and doesn't look too bad as a kit. Thanks as always for your great videos.
Very pretty. Will have to go on the Christmas wish list.
Nixie tubes are the Pinnacle of awesome
It's 4:30 A.M. on the southern cone when this is uploaded
Nice night gift Mat
That would look really nice in a picture frame like assembly.
I didn't know I needed this - but now I need this!
I like a lot of your demos on different equipment lease or are they cool I wish I knew some of the music that you played it’s really jazzy and sounds great I’m glad I found your TH-cam channel you bring forth a lot of interesting components.
Very interesting, have a problem with the power switch placement. The chassis is light, very light, each time the switch is pressed, the chassis will move, If the power switch is placed on top of the chassis in front, the unit will stay in place better. It might be best to move the other switches to. This brings to mind of the time when strobe lights and light organs were the thing.
this kit looks like a lot of fun to be honest
This channel has gotten me interested in nixie tubes. I still haven't gotten anything nixie related, but I still want to, and I'd totally be down to get a kit and put it together myself. Sounds more fun, plus I'm sure it's cheaper.
and now watch this: th-cam.com/video/9g-WU4oZAeI/w-d-xo.html
i know i´m spamming, but his work is so amazing over the top, he really needs more attention ;)
Wow, I like that, it's like dancing flames, love these nixie tubes.
Don't really need all that much skill or equipment to put it together. Just lots of patience and some logical thinking, mainly in the order u solder the parts in. Worst thing I see is that SMD IC jobby, but even that doesn't seem to be all that fine-pitched, and can probably be drag soldered just fine with some flux. So don't need a super fine tip and steady hand :) All in all it seems like a lovely kit. Lots of fun to put together, and oh-so-cool when working! Thanks for the video!
I like the "left - both - right" option, this way you can have two of them - one for each side :)
Nice idea, but I feel the heavy plastic 'bridge' near the top of the tubes is just too big. I would replace it with a very thin piece of drawn glass hot-melted too the top of the tubes.
A thing of beauty is a joy forever.
Hmmmm. This could work very well as a replacement for the radio dial screen if I need to replace all the innards of a radio furniture. Very intriguing.
I think I prefer the original front panel actually. It isn't sleek, but it really fits the fact that this is a nixie tube device. Those things have a certain aesthetic :)
You bastard lol i love all things nixie and could never afford to buy them and now you get me all tingly again with this one hope your happy lol,
Could possibly do with a box cover for protection, or to be really clever, a choice of clear, smoked or lensed / prismatic
