This is a macro pad in the shape of a snowflake. PCB can also be processed into a plate to fix the keyswitch.

This project features an e-paper display that shows real-time weather information, including temperature, sky conditions, humidity, and visibility. It's an energy-efficient solution with a sleek design.

In this tutorial, I will show you guys how I designed and assembled the humidifier circuit into the 3D model.

I used the new CrowVision 11.6" display under a lot of circumstances, not only with SBCs, and here are reported my tests and impressions

This is a very original, effective, and interesting example of a safe lock, which is almost identical to the large factory safes.

A fairly well-known and interesting montage

A simple and relatively inexpensive way to make an efficient DRSSTC (Dual Resonance Solid State) Tesla coil.

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.

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