Pete from PV Electronics sent me a link to a really cool kit that he has been working on. It is a GPS nixie clock kit that is offered in IN-8-2 or IN-14 tubes. This is a killer little design and all of the hard work is done for you. All you need to do is assemble it and build a nice enclosure for it (or buy the one pictured below).
Hours, Minutes and Seconds display.
12 or 24 hour modes.
Date display in DD.MM.YY or MM.DD.YY Format.
Alarm clock feature with programmable snooze (6,9,12 or 15 minutes).
Programmable auto display of date at end of minute.
Programmable Blue LED backlighting. Can follow night blanking.
Uses a Crystal Oscillator as the timebase.
Optional DCF / WWVB / MSF / GPS Synchronisation with status indicator LED.
Supercapacitor time backup for short power interruptions.
Simple time setting using two buttons.
Programmable leading zero blanking.
Calendar function has full leap year calculation up to 2099.
Five programmable neon colon settings (Flashing AM/PM indication, illuminated AM/PM indication, both flashing, both on, both off).
Maintains time during setup mode, eg. When changing between Standard Time and Daylight Savings Time.
Seconds can be reset to zero to precisely set the time.
Programmable night time mode - tubes blanked or dimmed to extend tube life / prevent sleep disturbance.
Separate modes for colon neons during night time mode.
Jürgen just sent me these new photos of the alternate enclosure for his Manuela HR nixie clock. The plexiglas in the final product will be a gold color. The plexiglas in the photo is actually a standard mirror finish that has been mocked up in Photoshop. And, for those curious, the tubes are Siemens ZM1182 clear tubes that were manufactured in January 1967.
