Making a Float Switch for a Corrosion-free Water Level Control

May 26, 2014

A float switch is a device which detects a fluid level (such as water) and activates a set of contacts which may be further integrated to a control circuit for restricting the fluid flow behavior. The advantage of a float switch is that it works without a direct contact with the water making the procedure free from all sorts corrosion or mechanical degradation problems,

Generating Electricity from Road Speed Breakers

May 23, 2014

Free Energy is available all around us in a variety of different forms, it just needs to be appropriately harnessed and used. One such example is our modern streets and roads where thousands of heavy and small vehicles pass everyday non-stop. The amount of energy transferred across the roads by these vehicles could be huge, and easily tapped, especially over the speed breakers where it's much easily accessible. The procedure and the circuit diagram are enclosed herein.

Twin or Split Battery Charger Circuit with Auto-Changeover

May 22, 2014

The presented twin or split battery charger circuit with auto-changeover illustrates a method through which two batteries can be charged and discharged in tandem by switching them appropriately across the charging voltages and load alternately. This ensures that the load receives a continuous supply of power irrespective of the actual source conditions such as a solar panel, wind generator etc. The idea was requested by Mr. Mohammad Zain.
