The first step was to purchase the parts necessary to make the clock.There are two main parts to the project, the nixie tubes themselves and some kind of circuit to power them.
Fortunately, I found PVelectronics, a UK based online shop which specialises in making and selling kits to make your own nixie tube clocks.
I purchased the Spectrum 18 kit for IN-18 tubes.
The next task was to find somewhere to buy the tubes themselves. They are harder to find than you may think, many places have no stock or have very small quantities in stock and therefore are extremely expensive.
Places like eBay are your best bet when it comes to finding some ‘new old stock*’ IN-18 tubes. I managed to pick up 6 tubes at a reasonable price from the Ukraine.
*Because the tubes are no longer produced anymore, people sell new old stock. This just means that they are new, never used tubes but were produced years ago.
