Look behind the scenes of nixie tube making

Cutting Pins for F Nixie tube | EP#3

Another version of a mold for manufacturing stems is in development. Meanwhile, I am trying the process of cutting wires to pins – this will be needed once the mold is ready..

We now ship also from the USA

Since I started manufacturing and selling nixie tubes and clocks, our customers from the USA formed the single biggest market for us. I remember years where we shipped 50% of our clocks to the USA. Today, I am excited to announce an improvement for our US customers – cooperation with Nicholas Stock from California. Nick […]

First sub-assembly – support of the stem – Project H #10

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 done using ceramics adhesive and it seems it will work. It is vacuum safe and it will provide enough support for the rest of the internal system […]

Project update – Project H #9

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 glass after sealing 7:25 – solder glass testing 11:20 – nitrogen purging setup 15:29 – connecting wires insulation 20:17 – anode cup manufacture 24:52 – ceramic parts.

Borax is not a suitable coating under high vacuum | Project H #8

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.. The borax layer (or the borated compounds) evaporates under high vacuum at 500C. I will need to find another solution.

Is Borax Suitable Coating for High Vacuum? | Project H #7

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 layer while copper-clad NiFe core would do the electrical connection which is easy to spot-weld to both stem and digit. Moreover, we have plenty of dumet already, […]

Thinking How to Drive a Panel of 121 Nixie Tubes | Project H #6

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 simply not deliver the desired experience. Our first idea was to use a master module with just a string of shift registers – we do this normally […]

Successful Window-Envelope Seal | Project H #5

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 chose might work. The tooling setup is temporary – I will make it safer and more productive later.
