In previous project we made (Do it you self . DIY Wireless electricity transfer Project. For making of simple wireless transmission of electricity. we used 2N2222 transistor and copper coil. The results of the project were amazing and we received many emails about the power and distance of the electricity transmission.
This Wireless electricity transfer system is very simple and powerful. It is capable of charging mobile phone, can also run DC motor and can also glow 3 or 6 volt tungsten bulb.
What is Wireless electricity transfer?
It uses inductive coupling, is one of the effective ways to transfer power between points without the use of conventional wire system .An alternating current in the transmitter coil generates a magnetic field which induces a voltage in the receiver coil. This voltage can be used to power a mobile device or charge a battery.

Material
The activity required some simple materials that are as follows:
- 26 to 30 gauge copper wire
- ttc5200 transistor
- 2 resistors of 3.3 or 6.6 k ohm
- LED
- Tungsten filament bulb
- Scissors
- Pliers/wire cutters
- Battery/ Power Adapters (12V)
- 4 Diodes
- Cylinder/role with 8 cm diameter
Components:

Wireless transmission of Electricity circuit Diagram
Construction
It consists of two parts,
- Receiver coil and Transmitter coil
Making of Receiver
- Make a coil of 25 turns and connect LED to it's ends.
Making of Transmitter
- Take a Cylinder/role with 8 cm diameter and whirl wire on it 55 times after leaving the wire of 3 inches now make loop for center terminal and whirl it again 55 times.
- You will get three terminals of the coil. Now take TTC5200 transistor and connect it's base to 6.6 k ohm resistor.
- The other terminal of the resistor will be connected to one end of coil and collector at the other end of coil.
- Connect the emitter to negative terminal of 12 V power supply or battery.
- The center terminal of coil will be connected with positive terminal battery and now transmitter is ready.
- Place the receiver coil almost 15 cm above transmitter and you will see LED glowing.
According to diagram one terminal of the primary coil is connected to resistor and resistor connected with the base of transistor
According to diagram 2nd terminal of the primary coil is connected collector of transistor

Wireless Electric Car Video 2
How can we use wireless power tranfser for large scale
its is used for charging buses and other vehicle on road or buss stop.
How to make more powerful tesla coil
we will publish its video tutorial soon
It works on higher energy ( watts ) than normal transistors.
Do you want to charge the battery or do you mean the inertia of the car ?
It depends on many factors. Please be more precise…
Does the wireless car have a battery attached? If you put 2 coils under the car, how far do you think the car can drive between the coils?
What is the difference between your transistor and a n2222?
what is cuircuit you used in pc fan
simple bridge rectifier and capacitor
