In this post I have explained how a neat little self regulating automatic battery charger circuit can be made using just two inexpensive transistors. This circuit will automatically regulate the charging supply to the battery depending on its charge level, by switching the input supply ON and OFF periodically. How it Works As can be […]
Self
Making a Self-Powered Generator
A self-powered generator is a perpetual electrical device designed to infinitely run and produce a continuous electrical output which is usually larger in magnitude than the input supply through which it’s running. Who wouldn’t like to see a self-powered motor generator running at home and powering the desired appliances non-stop, absolutely free of cost. We […]
Self Adjusting Automobile Headlamp Circuit
A suddenly dimming and brightening automobile headlamp is usually quite undesirable, since it causes a painful interference with the normal vision of the opposite side driver or the passengers. In this post we try to design a gradually self-adjusting automobile headlamp brightness circuit, which enables the brightness of the vehicle headlamp to vary proportionately in […]
Self Optimizing Solar Battery Charger Circuit
In this post I have explained a simple IC 555 based self optimizing solar battery charger circuit with buck converter circuit that automatically sets and adjusts the charging voltage in response to the fading sunlight conditions, and tries to maintain an optimal charging power for the battery, regardless of the sun ray intensities. Using a […]
