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.

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

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.

OpenAI Terminal is an AI-powered voice assistant designed for the Elecrow CrowPanel Advance. It enables real-time communication with OpenAI models via WebRTC, providing hands-free interactions. Users connect via Wi-Fi, authenticate with an OpenAI API key, and access features like live transcriptions and model responses.

A single board arduino nano controlled DCC accessory decoder for control of upto 16 servos with led output indication.

Beyond Beeps and MP3 Clips: Real Voice on MCUs.

Hands-free access. Just say the code out loud and the lock opens. Without Internet.

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.

This project aims to accelerate the process of identifying soil density values from the subgrade, subbase, and base course layers by integrating vibration, speed, and acceleration sensors connected to an Arduino Mega 2560 microcontroller. The data generated enables real-time monitoring and adjustment during the compaction process in accordance with SNI (Indonesian National Standard) 1738-2011.

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

In this tutorial, I am going to use the ULN2003 IC to create a simple, inexpensive water level indicator.

In this project, we will build a tiny internet clock connected to your wifi to get time from NTP servers.
