Voice-controlled robot interface using CrowPanel Advance and OpenAI. Spoken commands are interpreted via API and sent over Bluetooth to a robot. Works with CrowBot and can be adapted for other devices.

The future of air transport

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!!

Introducing our Advanced 8-Channel RC Transmitter and Receiver System a pinnacle of innovation for RC enthusiasts. Powered by STM32F103C8T6.

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

Most people are unaware of Cosmic Rays, yet they exist everywhere, unseen or felt. They were created long ago when primary particles get accelerated to near the speed of light by the tremendous magnetic shockwaves when stars supernova, black holes eat, and binary stars merge. The very same processes that thrust heavy elements made inside stars and other extreme events to form interstellar dust, asteroids, planets, and the building blocks for life. Cosmic Rays are an ongoing and continuous reminder of the immense scale, age, and complexity of the universe and the importance of science to our understanding. Building a Cosmic Ray Muon Detector allows anyone to collect data and visualise or make music from Cosmic Ray showers here on Earth. It is an opportunity to share an appreciation of Cosmic Rays: how tiny our little blue planet is, where it exists within the vastness of the universe, a precious, rare and fragile place, something worth protecting.

Build a miniature DIY FPV drone that operates fully on Arduino hardware for a fun learning experience and thrilling living room racing.

A replacement PCB for Hori Pad Mini controllers supporting software calibration & Hall Effect sensors.

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.

A Short PCB tutorial so you can make your first PCB.

This project is the development of a fully integrated, standalone Voice Assistant built upon the ESP32-C6 microcontroller. It leverages two major cloud AI services—Gemini 2.0 Flash for intelligence and Murf AI for realistic speech generation—to create a seamless, conversational experience for the user.

This project demonstrates a simple yet highly effective SDR (Software Defined Radio) receiver based on a dual-conversion superheterodyne architecture using two NE612 mixer ICs.

A custom IoT controller that manages street lighting over LoRaWAN and turns each streetlight into a fixed BLE beacon for proximity-based smart city services.

Discover the potential of the 2.8” ESP32 Miner Display by Elecrow: a compact development board that integrates a powerful ESP32 microcontroller with a TFT touchscreen, Wi-Fi, and Bluetooth connectivity. In this project we explore its features, hardware architecture, and development possibilities using the Arduino IDE. The tutorial shows how to configure the board, upload example code, and create graphical interfaces, turning this device into a versatile platform for IoT dashboards, smart home control panels, and embedded HMI applications.
