@@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. :(

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)

Brilliant as always Mr Techmoan, I'm all over that Kickstarter! cheers for assisting Jurgen

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.

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?

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.

It’s like dancing flames. Just beautiful.

Your videography is top notch Techmoan! Those shots of the Nixilizer were superb! :)

I was going to say the same thing. Those close-up shots of the tubes were gorgeous.

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.

that is gorgeous, the lights move so fluid like, almost like a fire or a plasma just flowing up and down in those tubes so beautiful.

You are the one who alerted me to the Nixie watches coming backout from Cathode Corner. Now I have the coolest watch in the world

Neat! Not too expensive and doesn't look too bad as a kit. Thanks as always for your great videos.

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.

Damn those are some sweet looking meters. So smooth!

Wow, I like that, it's like dancing flames, love these nixie tubes.

man thats really cool. ive never seen nixies like those before.

That is wild. I would LOVE to have one of these

Never seen one of these before now. Thanks so much for showcasing such a cool device! I can see myself staring at it in the middle of the night 🤪🤪🤪 and it's Midnight in Vancouver Canada!

This is indeed very beautiful.

Very slick, even for a prototype.. Like watching little jets of flame.

Thanks for the video and major props for pronouncing a german name right as a native english speaker, you wouldn't imagine how rare that is :D

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.

A thing of beauty is a joy forever.

Music at 4:37 is “Shoulder Closures” by Gunnar Olsen for anyone curious!

i just love the retro look of the nixie tubes. It would be really nice to design a car dashboard with these particular tubes.

Lovely piece of kit.

that looks really really good!

this kit looks like a lot of fun to be honest

Its beautiful from what I see!!

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.

Nixie tubes are the Pinnacle of awesome

I think I have found this years Christmas Present. For me that is.

Damn, that's one attractive design!

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

Great video as usual Mat.

This is gorgeous! I want one now!!!

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.

I really love that HP watch

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.

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 KZread 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.

I want one. I've always been meaning to get a nice clock too at some point as a gift.

That would look really nice in a picture frame like assembly.

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.

What a cool looking thing!

Your mechanical repair skills are very good. I can imagine you'd be good at building kits with just a little practice.

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 orange glow is really cosey! 🙂

Those close-up shots!

a longer and taller one of these would be sick

hey @techmoan, nothing particular to comment apart from that I appreciate your videos, You can tell there's a passion not just to for the more interesting aspects of tech, but also to share that information with others.

It’s both very cool and out of my price range.

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.

Another great video... Would love to learn more about the old Gas Driven Radio used in England around the 30s.

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

That looks pretty cool 👍👍

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.
