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.
