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!!

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.

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

This project aims to produce a fully assembled Meshtastic node based on the ESP32-S3 and RA-01SH, both of which are avaliable for assembly by JLCPCB. The only components to be bought outside are the antenna and LiPo battery. The PCB will include battery charging and SMA connector. Meshtastic® is a project that enables you to use inexpensive LoRa radios as a long range off-grid communication platform in areas without existing or reliable communications infrastructure. This project is 100% community driven and open source! Meshtastic utilizes LoRa, a long-range radio protocol, which is widely accessible in most regions without the need for additional licenses or certifications, unlike HAM radio operations. These radios are designed to rebroadcast messages they receive, forming a mesh network. This setup ensures that every group member, including those at the furthest distance, can receive messages. Additionally, Meshtastic radios can be paired with a single phone, allowing friends

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.

Cutting-edge farm security system that revolutionizes protection for agricultural asset.

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.

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

I built a scalable ESP NOW hydroponic network using 3D printed components and off the shelf sensors to automatically care for plants with minimal intervention, starting small in my apartment but expandable for future vegetable gardens.

This device secures high-risk tools by cutting off power to the devices. The electrical plugs are secured inside a metal enclosure. An IoT power bar allows power to be controlled using an RFID card reader coupled with an Arduino module.

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.

Effortlessly monitor your home's energy consumption with the DIY Smart Powermeter, seamlessly integrated with the user-friendly Home Assistant platform. This powerful project provides real-time data on your household's energy usage and offers the added convenience of a snapshot of your grid's status whenever you open the electric closet, thanks to the 2.9' e-paper display. Featuring an integrated 230VAC to 5VDC regulator, the ESP32-S2 efficiently harnesses power from surrounding wires for optimal performance. The Smart Powermeter supports up to six different CT clamps, with or without a burden resistor, allowing for versatile monitoring options. Additionally, it can measure ambient temperature, giving you comprehensive insights into your energy consumption and surroundings.

Encrypted off-grid LoRa messaging terminal with GPS sync and dynamic key destruction. No network, no trace, full control.

Provide to your favourites green friends with a DIY pot that let you know their needs!

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.

Introduction of the 5″ CrowPanel ESP32 Display, featuring a capacitive touchscreen and a resolution of 800×480. As its main control processor, it uses the ESP32-S3-WROOM-1-N4R8 module. This is a dual-core 32-bit LX6 microprocessor with integrated wireless capabilities, supporting both Wi-Fi and Bluetooth. It runs at a main frequency of up to 240 MHz, delivering powerful performance suitable for IoT applications.
