Hi! The end of the year is here, it is almost impossible to find the hours for making videos.. So, I made a quick update.. https://www.youtube.com/watch?v=3M_rtOOlPCg

This is the second prototype build of the H-tube, I fixed several issues from the first build - especially the front window sealing made me soo much happy [...]

All the major issues were solved, the time to make the first complete H tube has come. The main goal for this one is to tell us more [...]

We always used old oxygen concentrators to make oxygen for our glassworking burners. They troubled us all the time - for the H tube, we need more oxygen, [...]

Unbelievable, we have all parts for a prototype ready! I want to make the prototype as soon as possible to find possible design issues. First operation - cleaning! [...]

The digits for the new "H" nixie tube have just arrived! They are so large compared to the 50mm numbers in our R|Z568M nixie tube.. I am so [...]

We are building our own 30L/m oxygen concentrator to supply our burners for sealing the window glass of the H tube. As usual, there are things that need [...]

Almost all parts for the H-tube are ready, just a few are still in development. Let's hope the visually boring phase of preparation will be soon over and [...]

There are 12 weeks left to the final installation of the large nixie tube project. Still, a lot of work to be done.. https://www.youtube.com/watch?v=AsyxZFfMgic

It's time to finish the development of the first parts of the H tube - sub-assembly of the stem and ceramic rods. I designed this connection to be [...]

A bit longer video - I wanted to give you an update on progress in: 1:18 - upgrade of the glassworking equipment 5:28 - residual stress in the [...]

Another test made - it turns out that dumet wire with its borated protective layer is not suitable for use in a high vacuum. Maybe at room temperature.. [...]

A borated dumet wire would be a perfect solution for the insulated electrical connection between stem and digits inside the tube H. Borax would work as the insulating [...]

While working on the tube H itself, we have to keep in mind also the design of the electronics - without an absolutely reliable driver, the panel will [...]

Finally some progress - I succeeded in sealing of the front window. I still need to do thorough testing, evacuating it etc.. but it seems the design I [...]

The project of the "tube H" is running well, however, there are still some voids that need to be filled. One of them: I need to find good [...]

I made another step in the development of the "H tube".. In this video, I am trying to seal the front window into the tube envelope for the [...]

To successfully seal the glass window to the main envelope body, I need to develop a holder for the glass windows which is able to withstand high temperature [...]

I am starting a project of a new nixie tube - a large 150mm front-view nixie tube. This particular tube is designed for an artwork that will be [...]
