Description

I got inspired that tweets like "well happy 32/12/2020 everyone" so why not make a date gadget based on this idea?
It uses ESP8266 to connect to an NTP server and get the current date. Then it does some magic, and displays the 2020ized date to a TM1638-based display.

Components

1 × ESP8266
1 × TM1638 seven-segment display controller

Neat. What happens if it's still terrible after Mar 9? Month becomes 15? 🤔

Are you sure? yes | no

To meet the display constraint of 2 digits for the day, 99/12/2020 will be followed by 1/13/2020.

Do you have code? i'm interested in connecting to an NTP server and collecting the current date.

Are you sure? yes | no

I will soon, in the meantime you can have a look at the example code I used:

I had a hard time finding a simple way to get NTP time. Then I found Dave's code.
