Lupi-Nixie
This site shall be dedicated to my Lupi-Nixie clock. It uses russian IN-16 digit display tubes.
The clock uses a simple, but clever hardware/software design and is made mostly with SMT components.
Here is the ”feature”-list:
- 6x Russian IN-14 Nixie tube
- 2x Standard neon bulb (i got mine from RS Components)
- ATmega16 microcontroller – the only “intelligent” IC on the board, other ICs are discrete or linear
- Completely built with SMD technology parts (just a few parts are through hole)
- DCF77 receiver module (the clock has no controls for setting the time – totally control-less design)
The ATmega decodes the DCF77 signal, keeps track of the time, controls the multiplexing of the Nixie tubes and regulates the high voltage power supply (voltage can be trimmed with an SMT trimmer pot).
- Click here to see a video of the clock in action. Notice the fading effect, it got smooth transitions between displays.
- Click here to download the latest firmware of the clock.
- Click here for the parts list.
- Click here for the eagle schematics and board layout. Two versions included (one extra slim and the other optimized for an ALUBOS casing)
- Click here to view the schematics and here to view the board layout (just in case you don’t got EAGLE)
