Zen Nixie Clock – Update #3

Estimate reading time: 4 minutes

Middle of September is here – expected time of shipment of the Zen Nixie Clocks, let’s take a look at what is ready and what we are waiting for.

Case

Case is the main factor which delays the shipment – specificaly the aluminum stand. First batch of the stands had a small defect, it was rejected and manufacturer had to make the batch again. The stands are already manufactured and on the way to us, we expect them to come around 20th of September. Once they are here, they will need little surface preparation, then will go immediately for surface finishing – I expect 14 days to make it ready.

The glass covers are already manufactured and ready. We asked the manufacturer to use Optiwhite glass which is clear and doesnt have the typical green tint on edges.

Brass pillars which hold the electronic board on the aluminum stand are manufactured, prepolished and waiting for final finishing and gold plating. Gold plating protects them from tarnishing as brass would eventually do. Polished brass is first nickel plated, then gold plated. The nickel barrier prevents the copper (from brass) from diffusing into the gold layer, which would make the gold layer tarnish as well.

Electronics

The boards are completely ready, soldered, assembled and cleaned, waiting to be mounted to the clock stands. We cover all the high voltage parts with insulation layer to protect customer from accidental touch. The voltage used (170VDC) is not particularly dangerous, but you can get freaked out and drop the clock, hit the tubes etc..

The power is supplied to the board via the pillars – this makes the clock completely without any wiring inside. I use the metal parts to conduct the electricity – aluminum stand + 9 pillars forms the ground (negative terminal). The positive terminal is on the middle back pillar (isolated from the ground). All electrical joints formed by threads use electrical joint compound which prevents galvanic corrosion, dissolves the oxides and provides reliable electrical contact.

Nixie tubes

30 tubes for first batch of 10 Zen Nixie Clocks are ready, the rest is almost finished.

Packaging

Because of fragile nature of the clock, I ordered a proffesional packaging company to create packaging for it. The box is made from plywood, inside is foam which fixes the clock from movement. Uses also anti-corrosion bag and desiccant.

Available colours

There are currently two color options to choose from – Black satin and Silver satin. I had planned also a champagne gold colour, but it turned out that it is very difficult for the surface finish supplier to achieve consistent results with this specific color, so I decided to not offer it. If you are seriously interested in this color (or any other), please let me know – it is possible to have the parts for whole clock made in one order (stand + tube bases), so that the color is identical.

When I can expect my clock?

The only thing we are waiting for is the batch of case stands. I expect the package with stands to come in a couple of days, it will take another 10-14 days to have them blasted and anodised. Once this is ready, we will start shipping – I expect first week in October all the clocks will be shipped.
