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.

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.

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

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

“The Cyber Clock” , A rechargeable battery-powered 1.51-inch transparent OLED clock with accurate internet time and date. It can also measure your room temperature and humidity from an onboard sensor. It can show the battery percentage as well, with a fully 3D-printed Cybertruck body. It also comes with rollable wheels so you can play with it. It is also possible to lock the wheels by tightening screws so it wouldn't fall from the desk by accident !.

The TEF6686 radio module is intended for AM/FM receivers for cars. This time I will present you a way to make a portable DSP radio with this module controlled by an ESP32 microcontroller.
