I am new to the forum and would like to share my first few nixie creations. My clocks use german z566m and z5660m tubes, which are one of the most popular 30mm models on the market. All driven by reliable Spectrum 1040 kits made by PV Electronics. My personal idea for the case was very simple - glass top made of perfectly clear OptiWhite glass (no green tint) and a wooden base - CNC machined oak. Glass protects the clock against dust and reflects the orange nixie glow in a beautiful way. Wooden bases were prepared in two different color options - natural oak and black. Black color was obtained by using a Japanese Shou Sugi Ban technique. These clocks are now available on eBay (links below). Please let me know what do you think. If you have any questions please ask me directly.
