ESP32 Numitron clock

[nexus]

Hi all,

Being new to the forum, I thought I'd share my most recent project which is my one of my first serious attempts at embedded design.
It is a clock using RCA DR2000 "numitron" incandescent display tubes, controlled by constant current LED drivers and all run by an ESP32-WROOM module. It also currently has the capability for setting time over Bluetooth and I'm working on getting the WiFi up to automatically sync the on-board temperature compensated RTC with NTP.

Not too shabby for a mechanical engineer right?

Thought I'd put a picture up here as well.
