That story reminds me of one from work. Not Nixie-related but sorta funny :) Years ago, work had an IBM System/360 ot /370 of some age; It started having faults at random times, so they called in the tech. He opened the system covers, tied in all the diagnostics tools - logic analyzer, etc, but,

Im currently working on a pandicon-project with the 14-digit version (sadly i don't have a workshop and can only do woodworks outside, so "no working" in winter). This calculator helped me much to learn abou the pandicon timing. The gap between Anode 1 and Anode 2 is really "long" (400uS) so i'm

Dalibors tubes are wonderful and perfect, and the price is very reasonable no boubt about that. If there were newly made tubes in size of Z566M or ZM1042 this would be perfect, the Dalibor tubes are rather big, and for a clock to place on your desk or so they are maybe to big. Tubes in size of

Hi! I believe that the design shouldn't be entirely based on the existing tubes; if we can incorporate favorited characteristics based on general trends, why not? It's true, the thinner the mesh, the better. I do agree that wired anodes like on zm1177 improve visibility. Thanks for the suggestion:)

Hi John, you're right about how people shouldn't commit to buying a product that hasn't stood real life testing in the first place. I believe it promotes a culture where new manufacturers think it's fine to push out a product before its ready. I'm sorry if I sound unsubstantial; I had once contacte

Hi Nicholas:) I totally agree with you; considering that what we are planning to undertake is building a manufacturing process ground up, there would definitely be a huge number of pitfalls waiting for us. Most of them would almost certainly be different from what Dalibor had encountered too. The b

Hah! It isn't really about the QM, it is about the technology and the engineering knowledge. Your "we" had better have some real engineers in it! You are sounding more and more like a "Product Manager" as we call them out here. Once all the technologically-required steps are known, we get the I

I do wish you well with the enterprise Aiden but it sounded to me as if your first buyers were going to carry the venture and risk aspects. I have knowledge of Chinese manufacturing both back when trouble-shooting and very recently when doing the same for a mate who imports LED lighting. You bet

There is a very similar story about an early super computer developed at Control Data in the 70's. An AC outlet on the side of the machine was intended for engineering for debug instruments. But nightly, when the cleaning lady plugged in her vacuum cleaner, the machine would crash. It took da

Hello! I am sending few notes to this topic, from a perspective of someone who spent last 5 years exclusively in nixie tubes manufacture ;-) IMHO, $25 nixie tube is not possible. Nixie tubes were never so cheap, even in 60s, the less expensive tube from Burroughs was for $8 (equal to today's $

Dalibor’s information is surprisingly candid. He is also quite correct that there are many operations such as this which are extremely labor intensive. His videos are very educational and tell you a lot about what it will take to even begin to make Nixies. The investment to justify more autom

I do not know how to properly applaud Dalibor. It seems such an empty thing coming from myself. I am just an observer. However, I am so absolutely impressed with what he has done. It quite goes beyond the obsessive amateur radio guys filling a room with gear, the amateur scale-railroad enthusias
