Thank you so very much....I NOW understand. It sure is alot easier to wind a nail or spike instead of winding the torrid ring. This was the most useful video I've watched in a long time.
great explanation Ashton, and nice to meet you. I was always under the impression that the winding being in the opposite direction on the primary would be blocked by the secondary as an opposing field being that as the primary field builds and so to does the reverse blocking secondary field but your explanation gets me wondering . thanks for you effort😀
I just realised its been 44 years since formally studying this at tech college as a telecoms apprentice. You show it is still understandable without the maths! - great start.
solarhope cheers mate, my belief is that the maths is slave to imagination, a useful symbolic reduction for when we need something concrete to hold onto, but i think most of it can be visualised and understood without ever formally symbolising it
"A “Joule Thief” is a simple voltage booster circuit. It can increase the voltage of a power source by changing the constant low voltage signal into a series of rapid pulses at a higher voltage."
It's always difficult to know who your audience is on You Tube and their level of understanding. All in all, a very good operational description of the "Joule Thief" circuit. The only comment I would make is to avoid the use of acronyms such as EMF (Electromotive Force) without explaining what EMF is. If you use electromotive force in your presentation then counter electromotive force should also be explained and used, otherwise just use voltage. It's a small criticism, which indicates how good your presentation was. Thanks Ashley!
I think your on it mate! Keep up the good work, this would be a good video to redo, only make it shorter, more concise. One of the best joule thief explanations I have seen to date after almost a decade of joule thief learning and experiments. Big up to the Robert Murray of the Smith as well! BRAVO LADS!
4:10 Your diode is backwards in this diagram. When the switch closes, the inductor uses its stored magnetic energy to continue driving some current in the same direction.
Nice explanation - thanks. However, in the first diagram (beginning at 3:24) I think you are showing the LED the wrong way around. The back-EMF induced across the coil when you open the switch will be more positive at the switch side than at the 1.5V rail side, so you will need to connect the LED the other way around for it to light.
i finally understand this circuit.i have sadly watched way to many video's,but this explained it in simple terms.it can be replicated easily.RMS is a master at this game,if he hangs with Steve i would imagine he is very competent also.I'm glad you were allowed to join with them . i expect great things from you as this is one of my most trusted sites.no bs or tricks there ever.thank you
I have been watching you last week takeing kn everything your teaching me i love it want as much you asyou can put outaneedto know please more of old batteis know one had time to tel, me thank you ever much your new student G.R.P.
Ashley, if you want to take this to a next practical step, review a voltage multiplier. Image Intensifier is high voltage tube that runs on AA battery. Cold plasma another application with some very cool applications where this can be used. No end to what can be done with cold plasma device. My experiments investigating healing graphene defects with CP, if you want practical application. Cheers mate, you are doing good work.
Wow! So you have actually healed graphene using cold plasma? That’s like a Nobel Prize level accomplishment. Why haven’t you demonstrated this or published any papers? By the way, if it does work as you claim then what you have demonstrated is known as ‘negative entropy’ which is the second law of thermodynamics working in reverse! That’s bigger than Relativity in terms of its impact on physics.
Awesome thank you. ive never found a good joule thief explanation so black and white. Again thanks for making this and i look forward to more teachings in the future. A practical use for a joule thief is an earth battery light and/ or a crystal cell battery
Who is this bearded, meditating, mushroom loving, hippie genius? 😂😂 Seriously though, brilliant explanation! And it’s the perfect case study in non-linear dynamics. IE…how do you create a circuit that automates and regulates itself through non-linear phase and field transitions? That’s no joke, genius stuff right there!
Isn't the Diode drawn in the wrong direction? Because when the switch is closed the current will go through the diode not the coil. This is similar to a diode on a relay coil and normally the cathode of the diode is towards the positive rail. This type of arrangement is usually called the flyback diode. I could be wrong.
I have wired a Ferrite ring in parallel with telephone wire.... (2 sets of windings, counter rotating) ........and it will light the LED down to .31 V, with a TIP31 Transistor.....470 resistor ......................... at .31 V it stops working. Best coil I have made so far. Ferrite Tubes are noise suppressors in certain electronic cables, computers monitors etc THEY WORK GREAT !!! and are compact !!
I just stumbled onto you and this video and I must say very well said. Video editing sucked but your explanation was spot on. Now I have read that the type of inductor used helps with efficiency so you can go even lower so a nail will work, or any metal, but is not optimal as say a toroid. I know that it matters EXTREMELY which transistors you use and a germanium transistor has a lower starting voltage so that .7v to kick it on suddenly becomes .3 or .4 so even more of the battery, or an even lower voltage solar cell, can be used.
*+Robert Murray-Smith:* Where-ever did you find a soft-iron nail to use for xfrmr core? Almost *all* nails are made of mild steel = poor choice for xfrmr cores!
This is by far very effective, simple and to the point like you get explained by a proper Professor. Great job I must say. Now the meat & potatoes - as I have Joule Thief circuit which does Not use any Core (no ferrite or Iron, just a paper card core for support only). Then more interesting is that a smaller voltage say 1.2v Drive voltage not only runs a LED but also recharges a discharged Battery connected parallel to the LED. Then when the Battery B (discharged one) gets fully charged, when swapped around with the drive Battery A (which is now discharged) so that the Battery A gets the charging. In this manner if one keeps Swapping these Batteries (can be done electronically) then you get continuous power to the LED. Is this something possible or a myth. Kindly share some light
You can ommit the 555 timer in the relay circuit. Feed the relay coil through the normally closed contact. By doing that, the relay will turn on in the off state, and off as soon as the contact breaks. It's commonly called a relay buzzer circuit. If it is controlling different voltages you need a dpdt but if it's the same you can use a dpst. It has to be a double pole with a nc and no connection. Normally Closed and Normally Open.
Could've spent the 16 minutes walking to a shop and buying this magic for a pound in a cheap torch ffs. An led driver wow This guy needs to have a word with his mushroom pals, they're taking the piss out of him
You can go further and ditch the 555 timer get a relay the two separated contacts to build two separated circuits. The one switch (NO) is attached with the julethief. And the second relay switch (NC) is in series with the relay coil and the relay will buzz happily away like a buzzer. Note both switches have to be electrically separated they are two different circuits the are only mechanically connected in the relay.
13:30 did you just crawl from under a car you're repairing next door? Even academics can afford a comb, a bit of soap, a clean T-shirt and a less scruffy sweater
@ashley mills, excuse my ignorance but at 4:05 you say the direction of the coil winding is important to determine which way the magnetic field (and therefore the EMF) builds up when switched on (and then off) but doesn't an inductor always build up an EMF that opposes the current creating it, so does the winding direction really play a role or am I missing something?
Love the channel. I a bit puzzled when the relay and the 555 timer is introduced as surely that needs 12v and 9v respectivly to work .that is not referred to and seems to move away from the original intention of boosting a 1.5v battery to drive a LED
maxwell wrote about this. he noticed that the pulse after system was turned off had MORE ENERGY than original pulse!!!!!!!. to me that is the key to overunity. the key to overcoming back emf etc.
Very interesting and thank you for sharing it with us but I think the problem with this circuit for stepping up the voltage is efficiency which seems to be bellow %50. I wounder if a resistance load to collect the short cut phase of the oscillation would effect the circuit. ie. between Emitter and Ground.
I believe your LED is backwards in your whiteboard diagram around 4 minutes in... no? Looking at the coil: upon opening the switch, the lower portion of the coil will at positive potential, reverse biasing the diode.
what determines the on-off frequency, and by changing the transformer what range of frequencies can you create? Any shielding suggestions for use in an airplane??
At 1:28, "The electromagnetic field induces a magnetic field in the iron". Hmm. Put my mom's iron in the microwave to see by experiment, lots of sparks and bangs indeed, lovely magnetic field effects! Unfortunately it left the iron afterwards, in the form of blue smoke and won't come back.
"After I had meditated outside for a coupe of weeks..." Ha, classic, love it. And I liked the way RM-S looked round, at the amusing comment.Love the films gentlemen. As a bit of a youtube educator myself, I applaud what you do!Question: is there any way that old batteries could be utilised, via the joule thief (or other method), to help charge a 1 mega farad capacitor? That would be a nice way to use other peoples waste batteries to help power a home or car? Just an idea, sorry if it is patently ridiculous - my primary area of knowledge is the Human body/brain, and I got a piss-poor grade in my A-level electronics exam, lol.
Excellent Video Mr. Smith, How about a video on the current flow involved in a Joule Thief. You'll definitely need an oscilloscope to really look at that circuit. It's truly amazing
iluzyon1 Ash is a star mate - it's good to have him around - you should be in the lab - some of the ideas we come up with while chatting to each other is just amazing
Gracias por su aporte, una pregunta: es factible emplearlo en un circuito de Radio Galena sin energizar? con el fin de aprovechar las señales de radio frecuencia 🤔
13:58 "when the electric field collapses"? Which field is that all of a sudden, there are no capacitors in that circuit. Messy, messy, messy. Hope you're never found in front of a classroom...
Ashley Mills well you did a good job. The electric Magneto Effect en.m.wikipedia.org/wiki/Magnetoelectric_effect is what the basic idea of bouncing the energy is. "Mindful of Roberts rules," I thought you would find this interesting. It's surprising how well it works and how you can tune it. Cheers David A Puchta
Ashley Mills your welcome, FYI it's 10:02 Am in San Diego California and you responded at 9:30ish. I truly an enjoying Roberts channel and your addition is way cool. Sometimes a chemical energy-related relationship between friends can get amazing things done.
I dont know much about electronics - but this was clear and REALLY interesting. When you say that you can power a 3V device usiing just 1.5V of energy I Initially I thought "OMG free energy!" But then thought of the First Law of Thermodynamics - cant create something out of nothing. But what you are really doing is just making it more efficient ? Just wondering how this effects the overall life of the battery ? Anyway, REALLY well explained - I hope you go on to make other videos. Cheers!
there's no free energy here mate - you are right it is just an efficiency and depth of discharge thing - i have no idea on cycle life as i have never tested it - but that would be worth doing
Robonza anything that lowers the gate voltage will allow for a lower voltage driving of the circuit. there are some very sensitive field effect transistor's out there that trigger just from ambient RF, so there are some useful directions to go
i saw this article the other day www.aldinc.com/ald_zerothresholdmosfet.php but just in general, if you take any mosfet, the accumulated charge will often cause the mosfet to be on and you have to explicitly pull it to ground just to stop it from being spuriously on, I'm looking into this at the moment and how this can be controlled to create a lower effective voltage
So Goood. For several time I want to build a joule thief without know how it is work. Thanks Ash. I want to order the stuff to build a joule thief,could you tell what I have to order? Resistance, ferrit coil.... thanks
Mo Kha you need some copper winding wire, 0.25 or 0.5mm, a nail, a 2n2222 transistor, an LED, a breadboard, some joining wire, and a 1k resistor, but other values of resistor will work instead of the nail you can use a ferrite rod or a ferrite toroid, if you do use either of the latter then the number of turns needed will be much less, because the ferrite concentrates the magnetic flux much more readily than the nail does if you use a toroid for example, then you only need to do about 12 turns on either side of it to make the circuit work.
Thank you so very much....I NOW understand. It sure is alot easier to wind a nail or spike instead of winding the torrid ring. This was the most useful video I've watched in a long time.
***** cheers mate!
Ferrite works better, that is why it is used

I was always under the impression that the winding being in the opposite direction on the primary would be blocked by the secondary as an opposing field being that as the primary field builds and so to does the reverse blocking secondary field but your explanation gets me wondering . thanks for you effort😀
In your first diagram with the led in parallel with the inductor , you need to reverse the polarity of the led in order for the led to light .
I just realised its been 44 years since formally studying this at tech college as a telecoms apprentice.

Best explanation of Joule Theft on the internets I've seen (and I've seen quite a few). Full marks. Excellent video.
Ahh, the good old TNT revisited
Still so useful, still so worthwhile.
Brilliant video, I like how you started out with the conceptual foundations.
I've seen several explanations, I understood the basics, but this really made it crystal clear..Thank you..

Ferrite Tubes are noise suppressors in certain electronic cables, computers monitors etc
THEY WORK GREAT !!! and are compact !!
Is the LED at 3:30 facing the wrong direction? Like a fly back diode. But with light. Thanks for the detailed explanation!!
The best Explanation ever. Thanks❤❤❤❤
The LED at about 3:30 to 4:15 is connected backward in the whiteboard schematic.
He has most of it right, but not all of it. Specifically the turn of mechanism of the transistor. 11:20
wonderful wonderful explanation, the best explanation I found online.
Great Explaination. Inductors are fascinating. Thanks J.R.
Thanks so much for the simplification, i think my little mind can comprehend it now :)

Can u tell me the formulas to determain how many turn should i do to make those coils?
thanks at first.
That was purely awesome!!! Excellent mate ...thank you

How does joule thief- joules per lumen compare to standard LED joules per lumen?
Would a bifilar pancake coil help pull the current more?
How's Ashton doing? You ever check in with him and his family?
13:58 "when the electric field collapses"? Which field is that all of a sudden, there are no capacitors in that circuit. Messy, messy, messy. Hope you're never found in front of a classroom...
A nail will work , but Ferrite works better
So what can I make at home with this info. ? Anything I can use for security lighting, plant growing, or ? would be useful . Thanks

it was extremely educational, thank you very much.
Gristle Von Raben cheers man :D
noughtpoint seven volts means to me:any sorce of voltage ex. ground battery will be enough for lighting...
how can people do this with inductors only, no toroid? Some circuits achieve this using a capacitor and multiple inductors
Great job great explanation.
+Stephen Kramer cheers mate
so we can say it can increase or bost voltage ?
I guess if you use a germanium transistor the voltage could go much lower?
Robonza anything that lowers the gate voltage will allow for a lower voltage driving of the circuit. there are some very sensitive field effect transistor's out there that trigger just from ambient RF, so there are some useful directions to go
Ashley Mills I don't think you can get a gate (fet) voltage lower than a base voltage (germanium bipolar). Can you name a part for me to look at?
i saw this article the other day www.aldinc.com/ald_zerothresholdmosfet.php
but just in general, if you take any mosfet, the accumulated charge will often cause the mosfet to be on and you have to explicitly pull it to ground just to stop it from being spuriously on, I'm looking into this at the moment and how this can be controlled to create a lower effective voltage
Nice info.
Dan Murphy thanks
nicely done! :)

Mo Kha you need some copper winding wire, 0.25 or 0.5mm, a nail, a 2n2222 transistor, an LED, a breadboard, some joining wire, and a 1k resistor, but other values of resistor will work
instead of the nail you can use a ferrite rod or a ferrite toroid, if you do use either of the latter then the number of turns needed will be much less, because the ferrite concentrates the magnetic flux much more readily than the nail does
if you use a toroid for example, then you only need to do about 12 turns on either side of it to make the circuit work.
Thanks Ashley I will order these stuff. Very good video
TIP31 Transistor will give you way more light but uses more current
Ferrite works better
