This my first nixie clock. A simple clock using six Phillips ZM1040. The schematic and PCB layouts predate my use of Eagle software and so I do not have them here for download. Similarly the software (for the Atmel mcrocontroller) was written before I had migrated to CodeVision so again it is not available for download. The clock lives in our kitchen, has worked continuously since 2002 and is a constant talking point for visitors. Not a clock I look on as being a good example of the nixie clock builders art, but it does work and it was my first.
In 2021 after years of continous operation the tubes started to fail. They were already well worn when I bought them. So the clock is now retired.
