Numitron Clock

This is the first OTA capable Numitron watch made with an ESP32 WroverB !!! (At least the first one I have seen ;))

List of Content (Projects)

1. CNC PCB
2. PCB 1.0
3. PCB 1.1

• Gerber Files for a Numitron Clock and generated GCode (with flatcam) for milling a PCB (with grbl)
• Code provides a driver for the watch (can be found in the repository)
• Numitron Clock made for CNC milling (larger PCB and wider tracks for milling)
• Small PCB profesional manufactured not CNC capable (maybe if you have a LPKF or something it is possible ;))
• BOM, Schematics and Boards are provided in specific Project description

Features

• Clock will update its time and date from the internet via NTPClient
• A button press will switch between time and date (shown for 3 seconds)
• Because the clocks brain is a ESP32 you can basically view what ever you like from the internet on the 4 segments of the clock ;)

Known issues

• Clock is getting very hot -> due to AMS1117 if sufficient cooling is provided it should not be a problem. Will use a Step-Down Converter in future PCB 1.1 design.

Use this as a template for your projects it can be very handy in various ways ;). Please let me know if you have anything to improve or commit.

Cheers
