circuit diagram of coin insertion mobile charger

This is the smart coin based mobile charging system that charges your mobile for particular amount of time on inserting a coin. The system is to be used by shop owners, public places like railway stations to provide mobile charging facility. So the system consists of a coin recognition module that recognizes valid coins and then signals the microcontroller for further action. If a valid coin is found it signals the microcontroller and microcontroller then starts the mobile charging mechanism pro ....etc

Some materials have the ability to produce electricity when subjected to mechanical stress. This is called the piezoelectric effect. This stress can be caused by hitting or twisting the material just enough to deform its crystal lattice without fracturing it. The effect also works in the opposite way, with the material deforming slightly when a small electric current is applied. Piezoelectricity was discovered more than one hundred years ago and has many applications today. It is used in electronic clocks, gas ovens, inkjet printers, and many o ....etc

wirless mobile phone charger circuit diagram and component detail in hindi

Technology is one thing that keeps on changing to make life simpler. But, let s take the case of charging a device, for decades, we still confine to the old traditional style of wire system. Think of a device or a system that can charge up multiple systems without all those snake-look-alike wires. The solution is to go with wireless power transfer using inductive coupling.

Wireless Power Transmission using inductive coupling, is one of the effective ways to transfer p ....etc

piezoelectric mobile charger circuit mini project pdf

Description: When a piezoceramic trandsucer is stressed mechanically by a force, its electrodes receive a charge that tends to counteract the imposed strain. This charge may be collected, stored and delivered to power electrical circuits or processors.

The Piezo Bending Generator

When the Energy Harvesting Bender is flexed, one layer is compressed while the other is stretched, resulting in power generation. It may be excited by intermittent pulses or continuously from low frequency to res ....etc
