How to make a wireless power with old mobile phone charger.

 Introduction

WPT technology was purposed by “Nikola Tesla” in the year 1980. Wireless power transmission mainly uses three main systems like microwaves, solar cells and resonance. Microwaves are used in electrical device for the transmit-ion of electromagnetic radiation from a transmitter to a receiver. Wireless power transmission states that, the electrical power can be transferred from a source to receiver device without using any wires. This system consists of two coils they are a transmitter coil & a receiver coil. Transmitter coil is powered by AC current for the creation of magnetic field and receiver coil is used to observe the field.

1.Mje13003 transistor from an old AKT bulb circuit or either 13001,

 or D3331 transistor from an old mobile charger they will all work since they are NPN transistors they will work if you follow the circuit diagram below.

This is for an old AKT bulb

This is also for an old mobile phone charger.

2.Blue LED

3.5v DC power source.

4.wires 

5.copper wire

steps:

1.make the transmitter coil by making first a 15 turns then a center tapped followed by another 15 turns.

2.make the receiver coil by wounding a copper coil at 30 turns,

3.connect by following the circuit diagram and have your LED brighten up!!
