Interesting to see those IKEA cutlery drying containers being used (about 3 minutes into the video). I've often seen them used for all sorts of different purposes. A very useful product. http://www.ikea.com/sg/en/catalog/products/70179546/
The name ORDNING means "order" (as in "the opposite of chaos", not as in "telling someone what to do"), by the way.
This is really cool. I've been enamored with Nixie tubes since I was a kid, and I finally got my hands on some surplus CCCP tubes and started a project with them. I'm keeping somewhat of a diary of my progress with photos and videos in this collection of tweets about the process: https://twitter.com/jazzychad/timelines/773442085278085121
Heh, reminds me of when i first found out that the spare tubed a musician friend of mine kept around for his amp was CCCP stamped. Given that we are both old enough that we grew up during the tail end of the cold war, that seemed somewhat like consorting with the enemy at first glance. These days i wonder how much of the cold war, particularly after Stalin's death, was a massive US propaganda creation.
I think we can do a sort of differential analysis of the propaganda by looking at the coverage of events then and now. Back then, the USSR was repressing dissidents and engaging in proxy wars with the US; and became the universal bugbear, reviled in film and popular culture.
Nowadays, Russia is repressing dissidents and engaging in proxy wars with the US, including shooting down a civilian airliner; but the propaganda intensity is much lower. Is that because Russia is nominally capitalist and run by oligarchs who park their money in the West?

He is getting money, he started the business with a loan IIRC, he's located in the Czech Republic which means that the cost of some of those things isn't as high as you would expect. He's selling them at around 150$ per tube, his complete Nixie tube clock sells for 1700-1800$ and he's shipping these units about as fast as he can make them. The volumes aren't high but like with any other artisan crafted item they are…
Great to hear, after watching the video (I recommend 2x speed) it feels like he very much earned it, but starting this business with a loan, wow..
That's not necessarily a bad thing.
Artisanal vacuum tubes are a thing.[1] There's some interest in this from the vinyl record and overpriced tube amp crowd. There are even people who rebuild old CRTs for early TVs.[2] It's a lot of work. [1] http://hackaday.com/2014/11/21/artisanal-vacuum-tubes-hackad...

There's no vacuum in a Nixie Tube! That being said, it would be nice if classic tubes of yesteryear can be remade efficiently. Especially for antique radio enthusiasts.

Then comes Putin, clamps down on said oligarchs, and all of a sudden we are right back at cold war rhetoric.
As for repressing dissidents, lets have a look at the number of civil wars and whatsnot that was instigated by USA around the "free" world during the same timeframe.
I'm really, really impressed with the amount of work that goes into making these tubes and can understand why he's selling them for around $150, but what I don't get is how he can compete with the nixie tubes that go for under $10 on eBay. Are his better or more reliable?
I also noticed that Dalibor provides warranty — for initial batches, even lifetime warranty. That is very impressive and well worth the prices.
Glassblowing is a disappearing trade itself. I'm not sure what university chemistry departments are doing these days, an in-house glass shop with one if not several skilled glassblowers used to be pretty common. Likely it's cheaper now to have this outsourced.

I've seen this elsewhere and what baffled me was the startup aspect of it all. He spent 5 years doing this and a non-insignificant amount of money. How does he know it will eventually all be worth it? It seems like such a baffling risky step to take.
I can't imagine him getting back money that was spent on the equipment visible on the video selling these tubes. It seems to me more like the money wasn't a problem, and he just really wanted to start making these tubes (which is awesome).

If you know what you are looking for; you can buy used lab equipment very cheap. Most sellers don't even know what they are selling. You do need to spend a fair amount of time browsing. I've been thinking about a glass lathe on CL for awhile now. My problem is space.
What the frak HN?! Why is this have been downvoted to a flag kill?! This guy is absolutly correct! you can buy lab equipment on Ebay on the cheap, many sellers don't know and don't care.
Local listings are even better you can sometimes buy a whole lathe for "free" by just agreeing to take it of their hands these things are huge and heavy and the transport costs are usually higher than the cost of an old machine.
Here is an example of a Machine Shop Lathe for 150 GBP not that different than the Lathe He uses (He doesn't seem to use a glass lather with it's own heating elements, but just a glass chuck and a torch).
https://www.gumtree.com/p/other-power-tools/machine-shop-lat... (yes a "faulty" motor, which is usually fixed by a new fuese or a drive belt).
Here is a fully functional one for 500 GBP https://www.gumtree.com/p/lathes/metal-turning-lathe/1191030...
And here is a beast 15X50" refurbished lathe for 2500 GBP
https://www.gumtree.com/p/lathes/colchester-triumph-15x50-la... With his slightly smaller brother (more in line with the size of the lather the guy has in his shop from what I can tell) for 1500$ http://www.ebay.com/itm/CLAUSING-COLCHESTER-13-X-40-ENGLISH-...
Do they need work? sure but you can buy an entire shop for less than 10,000$ if you are buying used, have some patience and can fix things up (and if you are planning to run a shop and you can't fix your own tools, when sorry but don't bother unless it's a hobby you don't mind spending money on since if you can't fix 99% of the problems yourself you'll be out of business pretty quickly).
You can see from the wide shot of his shop that the lathe he uses is a pretty old one https://www.youtube.com/watch?v=awkzCmQ0kVA this isn't some high end CNC lathe, this is a pretty large prescision shop lathe which can be bought for Old lathes are the "free couch" (or almost) of the machining world, people can't get rid of them because they are too big, and they aren't a rare item to command a huge premium unless they are relatively new or highly specialized.
Other testing equipment is also pretty darn cheap, I've bought signal generators and scopes for <100$ on many occasions of Ebay and local listings which were probably worth 5-10 times more (and I've resold them after a short refurbishment).

As for your comment about MH317, I guess we all forgot about Iran Air Flight 655 where a US AEGIS guided missile destroyer which was arguably back then (and even now to some extent) the best radar system in the world shot down an Iranian civilian flight while violating Iranian territorial waters at the time. MH317 was a pretty bad and tragic incident but frankly IA 655 was arguably worse.
I had to rewind to make sure I heard that right.
