Clocks in a tubes always guarantee positive reaction. They are bright, unique and proves that you’re better than flashing LEDs. Cubeberg have designed IV-18 vfd display based clock. It is powered by Ti launchpad.

IV-18 is a vintage Russina tube. It needs a voltage booster to work correctly. It was build using voltage booster using MC34063. Display also needs a driver. Max6921 works well here. It seems that clock function is running in software. Additionally there is a piezo buzzer to sound alarm and optional DS18B20 based temperature sensor for display surrounding temperature. Author plans to put it in laser cut case after its finished.
