Picture of Wireless Power Transfer (Simple and Fast Way)
I've been searching about this topic for a year to make a simple project. However i found nothing simple. Every project contains hard to find materials and high voltage. I'm trying to make it simpler. I also find a Hungarian site about this project. But i made some changes. Schematic in this site will also help you. http://skory.gylcomp.hu/kapcs/

Step 1: Materials...

Picture of Materials...
Materials required;
(I give capacitors by using codes and values)

-  BD139 Transistor                                    /  1
-  5.1 K resistor (all resistors will work)   /  1
-  220n or 224 Capacitor                           /  1
-  4.7n or 472 Capacitor                            /  2
-  1.5pF or 102 Capacitor                          /  1
-  LED                                                            /  1
-  1N4148 Zener Diode                              /  1
-  Jumper wires
-  Cable for Coil 
-  9V Battery and Clip

Nice Job! However contrary to your title, this relatively complicated. If you are looking for a really simple wireless power project, check out my instuctable on the matter at: http://www.instructables.com/id/Simple-Wireless-Power/ . I think you'll find it easier.

Sir why you used center tap winding and which oscillator you used in circuit.

I have completed this construction and the circuit diagram is working perfectly and the maximum distance is 15 cm but the problem is if I try with a repeater than it is not working. Can you explain why??

Also, It is obviously a DC chopper...please correct me if I am wrong.

Well done you done better than me :)

plz send me the project circuit diagram and pdf plzzzzzzz

rakeshreddy961@gmail.com

thanks man. i think i made this project the same time as you. got it from the same source you did. lol

can you send me the project details with pdf file plzzzzzzzzzzzzzz @rakeshreddy961@gmail.com

This system is working upto how much distance?

the furthest mine went with 9v was 5cm with 50nF capacitor. :)

Atakan Atamert (author)  SELVAKUMARM10 months ago
max 10-15 cm

also i need a circuit diagram for your circuit (not the original one) for my physics project...........it will also be very kind of you if you make theory and all of this, just the way you did with slayers circuit

akhil.mithran7 months ago

Can you pls upload a video of this project.......make it quick plssssss

i made it but some one plz give me a report on it of about 35 pages plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz ASAP

I have done this project and the LED glows without diode :)
but i want to improving this circuit to charge 3.7 volt Li-Ion battery. Could you help me, what can i to do?
I want to me it like an adaptor wireless. Anyone can give me great idea ^,^

what is diameter of the both wires?

Atakan Atamert (author)  markk2110 months ago
you can change it but they must be same

I have done it but its not working

Atakan Atamert (author)  anayaka10 months ago
be sure to double check your connections(exactly transistor) if you done everything correctly it should work well

which type of cable do we need to use for coil

Atakan Atamert (author)  tejaswiv10 months ago
just regular stranded cable
HezrinHaze11 months ago
The diodes on the recieving circuit is not necessary and the capacitor increases the recieving range. :)

i have done the above project and the LED glows. how can i modify the above circuit so that i can glow a 60W bulb (or even a 15W CFL bulb) half meters away ?? how can i modify the above circuit??

dkols sr91 year ago

hi,
I have done the connection as per the circuit diagram.But LED didnt glow.Can u please help me to make the LED glow?....my id is dharshap@gmail.com.....I want to do it as soon as possible....

this circuit is just enable to on the led..it is not give requried voltage to charge battery...

what is the input resistance of the circuit????

how much watt is requried to operate this circuit??

what should i do to increase the output voltage and current of the circuit???

rply me fast.

am trying out this project for my science project. I I I made the primary and secondary as explained by you but it just don`t work. I did not use diode in my secondary circuit, is it a must.
Can you please help me
Atakan Atamert (author)  shrawan981 year ago
yes you must need to use diode to make electrons flow in one way
shrawan981 year ago
I made the connection ...but LED didn't glow...can u help me?
Atakan Atamert (author) 2 years ago
I'll help you if you have some questions

I made the connection ...but LED didn't glow...can u help me?

Hey guys can you help me? I´m on a hurry I don´t know how to make the three output coil for the transmiter. Could you help me by explaining how? My mail is jsvidal99@gmail.com
