Li-Fi data transfer experiment - transferring data using a Led and Solar Cell
Pavleski Aug 25,2023
 Li-Fi is a light communication system that is capable of transmitting data at high speeds over the visible light, ultraviolet, and infrared spectrums. The term was first introduced by Harald Haas in 2011. The Li-Fi system consists of normal LED light bulbs and modulating circuits. LED bulbs are semiconductor devices, which means the current, and therefore the illumination can be modulated at extremely high speeds which can be detected by the photo-detector.Using this technique allows ...

Mini Solar Light Project with a Twist
Arnov sharma Jun 28,2023
Greetings.This is the Cube Light, a Small and compact cube-shaped emergency solar light that boasts a power output of 3 watts. The light is equipped with a high-efficiency 5V 80mA solar panel, intelligently positioned on the backside of the cube. To ensure convenience and versatility, I have ingeniously integrated four magnets, allowing for seamless attachment and detachment of the solar panel from the main body of the light.This magnetic connection ensures a secure and relia...

Weather station receiver
Keshka Feb 17,2023
An add on for opengreenenergy weather station project. Debasish Dutta had provided the pc board for the weather station transmitter but no receiver board so I created one and added the ability to solar power it as well so it could be placed on a window sill.
