Share My Creation JG USB powered steampunk clock

Hi,

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 !
