The Beginning

My introduction to the world of Nixie tubes and clocks was because of a Steampunk lamp I built for my daughter’s birthday seemed to lack something on it. It was no doubt an interesting lamp, and something totally out of the ordinary, but it didn't seem quite... complete.

It had great big Edison bulbs, a rotary dimmer control, a Frankenstein switch, a pressure gauge, a voltmeter, copper coils and a valve that when operated switched on the two outer lamps.

It needed something extra and that is when I found out about Nixie tubes. The result is the clock on the right.

This was a good start, but now I had the bug.


I obtained a little FunKlock kit from PV Electronics, bought some IN-12A tubes and made a Steampunk designed clock to fit to the lamp which finished it off nicely. It was that warm glow of the Nixie tubes that got me hooked on them.

That was the beginning of making clocks to my own design and the clock just above on this page, the Oak Clock, was then the next case build on a PV Electronics FunKlock kit again. It is made from a stair spindle, a piece of banister and some 8 mm copper micro-bore tubing. It originally featured remotely wired IN-1 tubes as they were cheap to buy but I later found out that there is a reason why they are so cheap. One failed within months and they were replaced with CV5278 Nixies. Since that episode I have stuck to buying mainly European tubes for their reliability and longer lifespan.

Remote wiring is not easy to do when you have a 6 mm bore to feed through but it makes for interesting designs.

The buzz I get from making the clocks comes from designing the cases as I am not skilled enough to delve into the electronics side of circuit design and I stick to Pete Virica’s kits as they have proved reliable.

The Hands of Time

HandsOfTimeThe next design was using CV5278 Nixies again and I wanted a clock that would also look like a sculpture but did not realise what it would entail in the wiring department when I dreamed it up! This gave rise to what I called the Hands of Time clock. I had a nearby wood stockist who sold off cuts of hardwood and buying these saves a few pennies as you get some quite varied selections in a bundle. 

The elements of the clock case are poseable 12” artist’s mannequin hands, solid beech wood balls, plumbing back nuts, brass AM/PM shrouds with the wiring passing from one hand to the other. On the back there is a recessed control panel, and the clock runs with GPS time source. 

I like to design cases that are different from most and the next design was the most challenging that I have attempted so far.



AtomiumMy wife and I went to Brussels, and one day while we were there, we took a trip to visit the world famous Atomium. The sight of this massive metal sculpture was inspiration for my own version of it.

After a lot of head scratching and scribbling I managed to get a basic design that used the Nixie holders I had designed for my Oak Clock. I am fortunate that I have built up quite a good workshop that includes a lathe and milling machine. A rotary table was essential for this build as all the connection points for the tubing had to be exact and the recesses for the CV5278s and OG-4 Dekatron precise for visual enhancement. 

AtomiumBackThe design was originally without the Dekatron in the center of the clock, and only after stumbling upon them and finding a suitable Dekatron Spinner kit from ThreeNeurons (Mike Moorrees) on Ebay, was this added. This was a perfect feature for the central pod of the design.

All the brass work for the structure is converted plumbing fittings, the AM/PM, Alarm/GPS LED mounts and control buttons are made from solid brass, and the LEDs are embedded in clear epoxy which is stirred until it creates air bubbles in it.

This gives great diffusion of the LEDs light and their brightness is reduced by increasing the value of the limiting resistors. Rather than have the PSU and GPS sockets with nuts I designed shrouds for them with the original sockets epoxied and hot glued to the rear of the brass plate. It also has a power indicator between them.

More brass was used for the pod rear covers and the underside cover to enhance the look. Nothing beats brass and wood for cases!

I am fortunate that my designs have attracted some interest in that when Paul Parry featured them in his Bad Dog Designs website, a Hands of Time and an Atomium now reside in the US.

Paul Parry and Pete Virica have been exceptional in their support and solving issues I have had as I progress in Nixie clock building and my thanks go to them both for that.

Other Clocks

Other clocks I have are a little wooden cased IN-12A FunKlock and a wooden shrouded IN-8 clock that will be getting a makeover into something a little more enhanced with brass.

The Future?

Currently I have a valve clock in build featuring a great big thyratron inside a wooden case as a centre piece in the design to be lit by LEDs using ZM1020s for the clock display. There is also a Z566M clock that will feature a lot of brass on quite a simple wood base section that has brass and acrylic RGD LED light guides on the front of it.

A Spectrum kit based clock called "The Peacock" is already designed and will feature lots of acrylic light guides and RGB LEDs. A working 6 cylinder engine clock with the Nixies moving up and down on the pistons made in aluminium and acrylic but need a scroll saw first!

There is also my moment of total madness design, as Paul called it, in planning and if I can pull this off it will be unlike any other Nixie clock out there, but that is for the future. And finally, when funds permit it, there will be a clock based on Dalibor Farny’s excellent RZ568M Nixie tubes.

You just have to love Nixie tubes!
