    Here is my latest creation, yet another clock !

    This one is based on a IV18 VFD tube. You can find a lot of models on ebay.
    This one is a derivation of these !

    It is powered by a simple USB charger or any laptop USB plug. Then a boost converter increases the 5V up to 30V. And an ESP32 does the tricky multiplex of all the digits via an HV5812 driver.

    A B4A App is used to pilot the ESP32 with Bluetooth Low Energy.

    The design is rather compact.

    And the schematics minimalistic !
