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?
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
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
Hi, did your transistor turned hot to touch, because my tip35c did, when I applied 12V from a wall adapter rated at 1A max. Is this normal and will it damage the transistor if used often?
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?
You show in the drawing a 470 Ohm resistor but you are actually using 2x 220 ohm resistor in series, which is only 440 ohms of resistance. Which is correct?
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.
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 ?
Ludic Science Could I ask, If I have this close to my computer, like really close will it damage it, I will not using that to power my computer but to charge my phones ECT. so is it OK with the magnetic fields ?
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?
The pancake coil was made wrong. it should use side-by-side wire, not inside a outer insulation jacket. The wire you used has twists inside it, so the coil does not work as good as it could. Speaker wire or Lamp wire work.
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!!!
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
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 ?
I made this today, but it never transmitted any electricity wirelessly. Is there any common mistakes people make? can you help me trouble shoot? I used a 5W470 ohm resistor, a TIP35C transistor, 18 turn pancake coil with speaker wire, a small christmas light hooked to 20 turn magnet wire, and a 9volt. After I made it I went over your video and notes for a few hours trying to trouble shoot, I tried every variation of hookup to the transistor, but all with no success. Would you have any ideas of what might be going wrong or be able to give any tips? thanks
+Ludic Science Thanks for your help! I was thinking the christmas light wouldn't work. Yes, the battery is a small 9 volt, but it's the same as your the video.
Ludic Science Thanks, I managed to make the 31C work using 1K resistor. I had to go with a 9VDC source. AT 12V the power supply complains of an overload. Can I use this same circuit with this type of coil (see www.instructables.com/id/Wireless-Power-Transmission-Over-Short-Distances-U/)?
The output voltage on the receiver section decreases from 4v to 2v as it takes time. What seems to be the problem? I used the same components and a 9v power supply. Pls reply ASAP. THANKS!! :)
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.
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).
I made this but with 9v 600mA power supply and the transistor gets very very hot! and the voltage just reach like 2 volt. I think the transistor will burn if I use 12v 1.5A power supply
@@medtn because it's a different means of transmission .. this one is a direct draw from the battery .. which is being induced through a magnetic/di-electric field, where radio transmission is a pertabation of the Ether, same as light, just with a lower frequency. It's almost like asking why does a whole pile of light globes diminish after so many are connected into a circuit, but the sun doesn't diminish even though it illuminates multiple planets. It truly is an apples to oranges thing.
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?
So, is this kinda like a tesla coil then? I know you can get wireless electricity from the tesla coil at fairly good distances. Is this pancake coil like that?
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?
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 :-)
Very impressed by the work ....... how efficient do you think the process is ? ie you talk of putting 12 v in . What sort of wattage do you think you put in & get out ?
Could you tell me a way to use a different component rather than a resistor? I don't want to go through the hassle of buying brand new resistors for every project.
i need it for my science fair project so i have a few questions n mind..... (1).first of all you used a resistor tip35c can i use TIP41c or TIP31 instead of it? (2)and you used a resistor so that the resistor does not overload but wouldn`t it decrease the distance of magnetic field?so can use a capacitor if yes then where should it be placed? (3)can i used wire without insulator in primary coil? (4)what thing have impact on the distance of magnetic field?
+muhammad talha 1. yes but it manages less power, you will not be able tu use more that 6 volts input. 2. every transistor needs a base resistor. this circuit does not use a capacitor. 3. no. 4. you need a lot of extra power to increase the distance a litlle. If you increase the power 100%, distance will only increase a 10%, to put an example.
So the original plan is to fill the floor of a room with tiny lightbulbs / led lights in the size of a christmas tree deco lights, and the viewers who enter the dark room would be given a pair of slippers (with battery and transmitter attached). In my imagination, the lightbulbs would go on when the viewers are near enough, but watching your video made me realize that that might not happen, as the transmitter and the receiver of the device seem to have to be on top of each other (or at least right above each other) for the device to work. Is it possible to make something that's strong enough (or maybe I would just need to change the direction of the coil) for my plan to work?
+missyangster No, you will need a very powerful transmitter, something like 20 pounds in weigth with this kind of system. In your case, it would work better to have some kind of pressure sensors in the floor,so that when you walk, the lights go on.
Oh :(... Do you know approximately how much it would cost to install pressure sensors in.. say 1x1 square metres? Is it possible to make the pressure sensors myself, or would I have to order them from somewhere?
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
I didn't get the cause of induction.There should be a change in flux through coil. So either AC Current or relative motion. But you are using DC Voltage. HOW? Plz Explain.
I used TIP160 ..... the circuit woks with small battery 9V and transmit electric power at a distance of more than 5 cm only When i used 12V , 7A Battery , the circuit did not work??
QUESTION: Why doesn't the Max collector current of the transistor blocking oscillator become so large that the battery is damaged due to overheating ? same design as you have shown EXCEPT: 10 switching transistors connected in parallel , R = 470/10 = 47 ohm; 1 ohm load on the secondary. Answer?? the battery works fine, but ONLY for a limited design. is this true ? observerms
how come you cant just direct line the voltage to the primary coil and forget about the transistor and the resistors like lets say i sent 19 volts of dc current through that coil wouldn't it give off the same effect correct me if i'm wrong seriously because im just trying to learn i mean as far as i know the transistor is just a little micro switch that opens up when a certain amount of power is sent through it and a resistor does just as its name implys and resist the voltage but all that your doing is boosting and dropping the current with those right
You are the First one To Help About The Connection, Thankyou very much.

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.
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?
This is exactly what I was looking for. Thanks so much!
Hey can you give me the types of diode capacitors are used in your project??
Ah.. the principle of induction. Beautiful
Hi, did your transistor turned hot to touch, because my tip35c did, when I applied 12V from a wall adapter rated at 1A max. Is this normal and will it damage the transistor if used often?
+Viktor Božičević is normal for a transistor to be hot, but not too much. are you using a heat sink?
I have used a small one for tip31 transistor, but will try to find the bigger one and probably in combination with a small fan.

+Ludic Science Yes, I am using a heat sink. I'll try 1kOhm and see what happens. Thank you. :)

Great for start. Can you please explain if any calculations involved to select the coil thickness and number of turns etc ? Thanks in advance.

Wonderful Mutual Induction of cycloidal core. It has better future.
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 ?
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
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!!!
this might be a dumb question but are you using a diode because the emitting current from the spiral is ac ?

+Michael Nauert Hi. Are your 9 volts from a small 9v battery? then it will not work, those batteries do not provide enough current.
+Michael Nauert I mean using a christmas light that is incandescent. They need more power. With a led and coil it should work.
+Ludic Science Thanks for your help! I was thinking the christmas light wouldn't work. Yes, the battery is a small 9 volt, but it's the same as your the video.
+Michael Nauert Yes, that battery will work with a LED with a small coil
+Ludic Science Great, thank you so much for your help. I really appreciate it.
You just innovated a joule thief actually. Very clever.
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.
I made the pancake coil but I could not find any Tip35C. I have 31C. But I could not make it to work. My power source is 12vdc. Any suggestions?

did you wind the coil by yourself or you bought the wound coil and what type of coil is both the receiver and trasmitter..thanks
Fredrick Obarafor i built the coil, the transmitter coil is described on video. the receiver is just a single wire coil
yeah i know, i hav try this not workimg.....does it have any specified coil or coils use in building MOTORS can be use>?
Ludic Science, can you suggest any other transistor which acts in a smilar way as T1P35C does?
The output voltage on the receiver section decreases from 4v to 2v as it takes time. What seems to be the problem? I used the same components and a 9v power supply. Pls reply ASAP. THANKS!! :)

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?
130 people came here for the pancakes, but left (still being) hungry. 😂😅😆
can we use this technique to get 50v r any other technique is available to get 50v wire less current between two terminals

because the 36c is a PNP

Yes it will finish
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

+CUBETechie No, those radiations are extremely low power
What does the transistor do?
sir what do you called insular that put two wires inside ?it is just an insular...thank you its very helpful to me?
Insulated, i`ts a interior telephone cable, two wires inside.
thank you
Garry Anole you´re welcome.
how come you cant just direct line the voltage to the primary coil and forget about the transistor and the resistors like lets say i sent 19 volts of dc current through that coil wouldn't it give off the same effect correct me if i'm wrong seriously because im just trying to learn i mean as far as i know the transistor is just a little micro switch that opens up when a certain amount of power is sent through it and a resistor does just as its name implys and resist the voltage but all that your doing is boosting and dropping the current with those right
+Jesse Hefner you need the transistor to make an oscillator circuit.
@@ludicscience but why do you need an osculator circuit?
