Wire up your RGBW LED strip to Wi‑Fi with ESPHome! This 12 V controller drives four PWM channels—R, G, B, and W—using a simple ESP8266 board. Ideal for Home Assistant, perfect for ambient lighting, and totally local.

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!!

Tidesy is an innovative tide tracking device designed for coastal adventures and enthusiasts. Whether you're a surfer, sailor, or beachgoer, Tidesy delivers real-time tide updates to enhance your ocean experience.

RGB Control System With ESP32-C6

An Arduino Mega–based robot plotter that uses DC motors with encoders, sensors, and G-code interpretation to accurately trace shapes, paths, and drawings. Designed as a low-cost, customizable platform combining robotics, automation, and creative design

Artificial plant with environmental monitoring

Extract data items from a mmWave sensor, train a NN to diagnose pipeline defects, and inspect results w/ deformed pipe images on a web app.

Turn any wired doorbell into a smart Home Assistant trigger! This PCB uses a D1 Mini and optocoupler to detect the bell press directly from the existing transformer, no additional power needed. Fully isolated and ESPHome-ready—just wire it in and go.

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.

Is there an easy way to freely connect several music sources and their multiple receivers at home? Yes! Even if entire environment should be integrated with a COAXIAL-SPDIF switch for the audiophile sound quality? Sure, recently I built the switch that can do that. But now it's time for the main question, is there the easiest and most intuitive way in the world to manage required connecions? To allow anyone seeing it for the first time to control it without any learning? Of course, now there is! All I needed to breathe a new life into my music center is the HMI panel from Elecrow.

WiFi-Enabled, modular prototyping platform for creating and testing electronics projects with ease.

eBUS Adapter Stick C6 is a reduced size version of previous highly demanded eBUS Adapter Shields and provides an interface to a 2-wire eBUS with galvanic isolation for enabling communication with an eBUS enabled heating, ventilation or solar system. With a size of 42 x 16 mm it is way smaller than the previous Shield versions, but still supports an USR-ES1 module being plugged onto it for having Ethernet access. Even better, with the upcoming firmware version for the ESP32-C6, it automatically scans the heating components and makes all data available via MQTT to e.g. Home Assistant with auto discovery of entities.
