Hi, I'm a Rudolph and you know me from Santa's Stories, and I'm here to help him to bring messages from all around the world directly to your Christmas tree.

Nowadays with some travel restrictions, Santa's asked me some genial Ideas to make happier people, and looking at my desk I found some DIY materials and with some effort, I've created my first IoT device (I'm fancy). Let me show "my precious":

I've got an Espressif MCU called ESP32 (in Node32s dev board) and an Oled display (SSD1309) with 2.4" and 128x64 pixels, some headers, and a cool PCB (did you like?) that works with a Firmware that can connect to the Internet and receive messages from a Twitter account and show on the screen.

First, you will need to configure Internet Connection, and after you will be guided to get your Twitter API credentials and spread two the world how all the universe can send a graceful message directly to your Christmas tree.

All this hard work make me tired, and you know, in a few months I need to help Santa again, the Firmware code is an Open Source art of code, and you are invited to help Santa too, come with us spread happiness around the world
