Identify noxious air bubbles lurking in the substrate w/ ultrasonic scans and assess water pollution based on chemical tests simultaneously.

Weather Crow is an ESP32-S3 based weather station featuring an E-paper display that shows current weather conditions and forecasts. This initial release provides a complete solution for monitoring local weather with minimal power consumption through efficient deep sleep cycles. the project is under the MIT license, so you can modify or chage as you want!!

A ready-to-use weather station. Quick setup: flash the prebuilt firmware and start testing in under a minute, no coding required. Open-source and customizable for your own weather-based projects. Firmware and source code available on GitHub.

The DIY Heating Booster helps you get more out of your existing radiator – without modifying your heating system. An ESP32 controls 12V fans mounted underneath the radiator, automatically turning them on when the radiator gets warm to efficiently distribute heat throughout the room. The control logic works standalone with a local temperature sensor, but can also be fully integrated into Home Assistant. Perfect for cold spots, smart upgrades, and energy-saving DIY solutions.

In the year 2021 I created a "Internet Hardware WatchDog" using NodeMCU which reboots my home router whenever there is an issue with the Internet. This device sits next to my router and happily takes care of it whenever it has a hiccup. This year, I wanted to extend the watchdogs horizon by adding an "Internet Status Notifier" that displays the current status of the Internet using an RGB LED.

Build a Digital Timer Switch that allows you to switch devices on or off on a specified schedule, e.g. your garden sprinkler or lights in your home. This Digital Timer Switch will always have accurate time since it synchronizes its clock with an internet time server. No need to adjust the clock for daylight savings time or to set it after a power outage. Furthermore, the large display makes it easy the set or change schedules.
