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

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

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

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

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.

XRC PRO is a powerful, open-source RC transmitter and receiver system using STM32 and NRF24L01. It features real-time control.

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

This is certainly the cheapest and simplest Internet radio that you can make yourself if you have minimal knowledge in the field of electronics, and all thanks to this universal and practical display module.
