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.

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

A wrist watch on rare vintage LED dot-matrix HDSP-2000 indicators

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

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

Buying a ready-made power supply would be too easy, so I decided to make my own.

Effortlessly monitor your home's energy consumption with the DIY Smart Powermeter, seamlessly integrated with the user-friendly Home Assistant platform. This powerful project provides real-time data on your household's energy usage and offers the added convenience of a snapshot of your grid's status whenever you open the electric closet, thanks to the 2.9' e-paper display. Featuring an integrated 230VAC to 5VDC regulator, the ESP32-S2 efficiently harnesses power from surrounding wires for optimal performance. The Smart Powermeter supports up to six different CT clamps, with or without a burden resistor, allowing for versatile monitoring options. Additionally, it can measure ambient temperature, giving you comprehensive insights into your energy consumption and surroundings.
