E-Ink Info Display

I’m building a compact e-ink dashboard using a 2.66" Waveshare E-Paper display and an ESP32 microcontroller. The dashboard shows: The current time and date Local weather (temperature, conditions) via the OpenWeatherMap API Upcoming events from my Google/Apple calendar Optional extra info like a daily quote or fun fact The goal is to create a low-power, always-on display that consolidates important information at a glance.

CO2 Monitor

This project uses an Arduino Uno R4 WiFi and a K30 CO₂ sensor powered by a 5–9W solar panel to monitor live CO₂ levels. Data is uploaded to a custom HTML webpage, enabling real-time environmental tracking. The system is designed to be scalable, with each unit costing around $200 with solar power and $130 for the plug in version you can see cleaner code and other cool stuff at this link https://blueprint.hackclub.com/projects/834
