This is awesome, thank you for these videos. Great channel :)
You are the First one To Help About The Connection, Thankyou very much.
This is exactly what I was looking for. Thanks so much!
Its amazing how many people are impressed with this simple transformer action with magnetic fields. 40 years ago our professor showed us lighting a 40watt flo lamp from the TV Transmitter tower 5 miles away . That was impressive.
+roy douce Me too, I was amaze why the fluorescent tube lamp lights on while there were no wire connection in a radio transmitter 30 years ago.
Very intresting, I will need to try this sometime.
Thank you for sharing I think I would like to try this one. 👍🏼
Very good video thanks for sharing.
Great!
You have given a good explanation of wireless electricity.
Great for start. Can you please explain if any calculations involved to select the coil thickness and number of turns etc ? Thanks in advance.
this is awesome, thank you, I will be making this
Hey can you give me the types of diode capacitors are used in your project??
wicked cool man thanks for the video
My question is, if you close up the LED to the base, the current increases right? Would that burn the LED if you don't have a resistor on it?
You just innovated a joule thief actually. Very clever.
Do you know if a neodymium magnet put in between this 2 coils interferes with the electricity transmission?
What a way I can transfer 20-30 W 0.5 meters away? 12V 2A would be needed from the side of secondary, which produce heat. Thanks.
Wonderful Mutual Induction of cycloidal core. It has better future.
Is it possible to build an induction battery charger with super capacitors, boost converter and induction coils to use magnetic field as a power source that builds up around a DC (in-runner/out-runner) motors?
what is the guage of magnet wire? please help me out
Can I use pancake coil with 12 turns? Please help me. I didn't find wire more than 3mts and it makes only 12 turns. Can I use that? Please reply and help me quickly
great work... what is the diameter of the wire you have used? does the wire diameter make any change?
Ah.. the principle of induction. Beautiful
Excellent and more than excellent.
I wonder what would happen if you put another smaller coil above the larger but have the currents going in opposite direction with different phases?
It's a nice video but I have a problem when i use this technology on charging the phone.
Can please you tell me the votage in the emitter coil that i can got about 5V on the reciver coil when the distance between reciver and emitter is 5cm or 6cm ?
what factors apply to the coil? lenght of wire,resistance,etc.
hello nice experiment, what diode did you use for the dc motor, i will try to make my own. Cheers
That's a nice Canary you got there (singing in BG).
Very nice videos and I like it .
what are the effects with less turns on the coil and why the 5 watt resistance?
nice ,but plz answer :
if i want to use 5 volt as supply what type of transistor i need to have an output of 5 volts with use of coils?
plz tell me the names of components u used in circuit
This works, thanks for the video.
kindly tell me that the resistor (470 ohm) used in the circuit is either 5watt or 0.5watt?
thanks
I enjoy your easy to understand Demonstrations..Thank you...
Nice Video. Great project for anyone.
i love this...pls where can i get coil pancake coil,its posssible to make the matching coil and HOW?
can i use any kind of wire to form bifilar coi? is it ok to use stranded or solid wire?
Very good and amazing project .......Well done
Thanks!
I cant seem to get this to work, ive ordered coils that are already coupled . im able to get a magnetic flux through the coils from my power source but i cannot complete the transmission process
very nice Ludic
+Jaime Perez Thanks man
can i make a small coil for transmiiter because i want to make a wireless charger with the same circuit
for more then 20v input which transistor i use & how u calculate base resistor
????
can it be done using a single wire(eliminated copper wire) of 27-30 gauge?
TIA
How is its working different from a tesla coil? And why do the LED etc also require a coil in this circuit whereas in tesla coil the CFL and LED light up without a coil attache to them?
Very nice videos and I like it
Good day sir, I attempt to replicate this project. However I consistently pulling 0 amps into the coil. The only difference is the transistor i am using and possibly the wires. Can you offer any advice please?
What would happen if you laid Both receiver coils on top of the Pancake at the same time ? Would they cancel each other out.?
How can the transistor work with the big battery
Very nice Video.
good demonstration of electric induction.
can we use this technique to get 50v r any other technique is available to get 50v wire less current between two terminals
This works perfect.
just finished mine and tryed it on 3.3 volts of a computer supply.
3.3 because i dont have a heat sink yet which i recommend if you go higher in voltage.
the transistor gets a little warm already.
I used a tip35c transistor and a 5 watt 470 ohms resistor.
for the coil I used speaker wire held together with hot glue.
thanks for the great explanation
Bob Jeuriens what guage is your reciever coil made up of
it is just a simple cheap wire from an electronics store.
i have to gues that it is AWG 22 or 24.
Ludic Science, can you suggest any other transistor which acts in a smilar way as T1P35C does?
Very good thanks for sharing
hey man which transistor you are using on this video?
please tell me soon,i am waiting for your information.
My TIP35c get very hot. I have tried different resistors but no difference. What can I do go reduce heating without heat sink ?
what is the significance of the number of turns and is there any law on the no. of turn present ??
pls tell
Can someone helpp me I couldnt get a TIP35c transistor so can i use a TIP3055 transistor very urgent
That's awesome. My mind hath been blown. :D
So theoretically, if the joule thief coil was connected to a power supply of a reasonable power, and the second coil was attached to a 5 volts regulator and a usb port, it could be used as a wireless charging solution for a phone (within a fairly small range of course)?
Haseeb Malik In principle yes, but modern phones need a fairly large charging current, around 1 amp. This device will give you a maximum of 400 ma (less losses from the regulator).
Thanks for the great tutorial! I was able to make a circuit working with USB power but the transistor heats up way too much. It works for like 30 minutes and then it stop working. Should I increase the resistor value? I'm using the exactly the same ones from tutorial; TIP35C, 5W470ohm x 2, with USB 2.0 output of 5V and 0.5A. Could you please help me out?
+Min Kim yes increasing the base resistor should help. Try 1 kOhm. Are you using a heat sink?
+Ludic Science Yes, I am using a heat sink. I'll try 1kOhm and see what happens. Thank you. :)
can I use this circuit for making wireless charging for my mobile is it safe or not?..
Is there any design like this that can produce a current of 1 ampere?
Ok, really stupid question (I'm not an electrician), but can these circuits be used in-reverse? Like can the pancake coil act as a collector rather than to transmit electricity? Love your videos by the way!!!
What is your input voltage and turns of secondary coil ?
Brilliant!
can u explain its working .I made it my science model for my school project and have to write its working in the project file .please help.
If we move the receiver coil in the horizontal plane, it should not make any difference, right?
works better when it is in the center of the emitter coil, so it does make a difference
Hola, pude armar el mismo cirucito y me funcionó. Lo usaré para un proyecto. Sin embargo, debo hallar el voltaje y la corriente de ambos circuitos teóricamente. Me gustaría saber si debería usar formulas sobre circuito RLC o si me puede dar alguna referencia para investigar. Gracias
can i use a normal wires for the base coil as well as the receiver coil. pls inform fast very imp.
must use bifilar wire fot the base coil
@LS what is the use of tesla bifilar pancake coil here?means what is its main advantage?
in this experiment .. pretty much none .. although a slightly different winding of the coil which would make it phi, would probably give a slight increase in the distance which you can cause the induction. These coils were initially designed to be able to work as capacitors more than just basic induction circuits, as N. Tesla found it hard to find suitable store bought capacitors that would sustain the experiments he was doing at the time. It was one of his frustrations.
What about combining wireless transfer with a joule thief to allow a detachable LED to burn a long long time when connected. Maybe a coil doing double duty ?
Good i am searching for a witricity project to drive a motor finally u did it , but i want to know this is useful for 2 motors or not ... can u send me a graph of secondary coil output with repect to time and Thank you
how is the coupling factor is done without capacitor? @lucidScience
What does the transistor do?
Tell me the rating of diode used to the mini motor
thank you!
Mine is not working properly.When everything is connected properly, the led does not glow.But when I strike two connections the the led will glow just for a fraction of a second.what is the problem.is it there a problem with my transistor?I've used the same as yours.
would you need different materials for more power
will this work in charging battery. so instead of led I will put battery connected to coil then put it to the top to charge
+JD Punzalan yes
which transistor is use ? please to tell about transistor number
what is the input limit ??/
You became my hero...!
thanks for the video helped alot
:)
Thanks!
Hello sir I am from India I want to know how much voltage this transfer DC kindly tell me
I want to power a small LED with its receptor coul about 12 cm above a wooden base plate into which I'll put the slayer coil. But there has to be a mirror immediately over the coil which will hide it from view. Would the mirror's thin coating of aluminum interrupt the field and prevent conduction of electricity across the coils?
I think it will interfere, however I have not tested it
That's what I suspected. The pancake coil you show would fit nicely in my base, and I could make it with wire less thickly insulated than what you have, thus increasing the number of turns in the coil, if that would help. Your receiving coil is also about the same as what would fit my project. I could reduce the distance to maybe 10 cm. Suppose I put 18 volts to it with sufficent power. (Plus, suppose an ideal resonance could be tested and set up between the coils.) If there is possibility of success I think I'd like to try it.
May I ask you to put a mirror above the coil at various distances, with at least 10 cm between the mirror and the receiving coil, to see if any current will pass through the aluminum coating? Test it for me? I'd be very grateful :-)
Thanks amigo
what transistor can i subtitute to TIP35C?
Good one bro
Can we use mje 13007 instead of tip 35c
with something to detect lux levels, this could be an Interesting alternative to ultrasonic object detection? or maybe for other things involving proximity...
I am confused. I just looked at the slider2734 video. It does not show AC being applied to the input coil, just a DC battery input. It also shows the original Nikola Tesla circuit drawing showing application of a DC source. What exactly is turning the DC source into an AC waveform applied to the pancake (input) coil ?
The transistor
I tried this circuit , the motor is not working.could u specify the dimensions of the wire used to make the pancake coil. I used a 2 core wire made of copper. In the circuit diagram there is only one resistor, but the video shows 2 nos. what is total resistance at the base of transistor?
+Rajani Suresh I used old phone cable, the size is not critical. I used two resistors because i did not have the correct value. Check your connections, something must be wrong
How to deal with the tip35c heating issues?
What is the method to make a 200 Watt Wireless Transmitter and Receiver?
what type of wire is this using specifically i know u said 2 wire cable but i want to make sure that i get the right type
mine is telephone cabble
can anyone please provide the link to order the pancake coil, please........
how many amps i need for need to my power source?
What is frequency of the primary coil current?
