Dude I've been trying to get this simple circuit to work for ages yet I has no idea the two windings were suppose to be in opposite directions. No one seems to explain that and the schematics don't necessarily show that. Many thanks!!!!
I finally got all the parts. So far I finished two circuits of the first part of your video. Both work well with 1K resistor not 220 Ohm.. I also inserted 1,2&3 LED's. Everything is great and functions on 0.8 volts ( dead battery AA)or less. Next will be using a solder board. Again thank you for your video.
Any toroid with two windings of 20 turns should work fine, This circuit isn't all that fussy about component values. It might be better to use a larger transistor if you want to run lots of LEDs.
How do you know which holes to stick the components in ? I am a newbee and just purchased a breadboard with jumpers from Rad. Shk. But it did not come with instructions ! Where can I find out how to use it ? Thanks (too many holes )
Thanks for the video and the presentation. This drives most viewers including me to try it provided parts can be easily acquired. Will save this video for future reference.
Hey! i'm trying to build one of this connected to a 1.5V AA battery. Could you tell me for how long would the LED's be on for just with the AA battery?
MAN you are a teacher, You should do this stuff for living, the way you do it simple step by step that is what I was looking and I had been looking weeks now, and now I got what I want to see so badly, You should do DVD's with difference projects on it, I sure would buy your DVD's for sure, It is good that you do it, it helps some many people that are in to difference projects and you are a smart guy, it is you are doing it for free and thank you so much for shearing it. Thank you from Calgary, P.S. I have birds, and I'm using just the timers on the light, But I want something that would mind the lights from full to dark in one hour in the evening, And than in the Morning from no lights to lights on with in one hour. Do you think you could make something that I could use for that? even if I had to have it hooked up to a computer? Thank you Peter from CALGARY
+Pete Frise Send me an email about what you need, I could possibly build it for you. Zoorated@gmail.com. Also thank you for the feedback. I have a bachelors degree in electronics as well. I really enjoy this stuff.
I can't find a datasheet for "S0038 transistor" Where did you get that transistor from? Also, can you provide a detailed description, part number, & inexpensive vendor for the toroid-shaped ferrite core?
I found my S0038 transistor in my spare parts bin. I am not sure where the datasheet can be found if you can't find it online. As for the the core, I find mine in old computer power supplies. Try to find junk electronics to take about and find parts to use.
Could you provide the approximate measurements of your ferrite core? (e.g.: outside diameter, inside diameter, & width) If you have a caliper, it would nice to know the wire gauge of the core windings. Thanks
That's a great Toroid core. Did you make the base for it?? I don't see one like that via the link to Banggood you provided in comments below !! All of theirs just have open leads at the bottom of the windings. I'd like to get/make a few of those !!!
ZooRatedProductions Thank you . I , with finger in the wind knowledge , would suggest , they would be found , notably lossy , as it is a brew of resistance - heat loss & collapsing magnetic field ...... but I not suggesting it can be bettered ....... without more up front cost & madness . I think the term that you comes to hand , would be cost effective .
ZooRatedProductions That ' s the trouble with instrumentation , it is sometimes more difficult to understand what it reads , than if the reading is correct . The transitory becoming the definitive .
You cat looks like a tabby like mine(Isabelle) that passed away last February..16th..so not a good month for me...I love this well explained video..thanks....I am trying to make an LED memorial using your video..and using 3-6 LED's...to light it..
Thanks for the video. I build it with your instruction and it works perfekt. I got it work with 0,92v. My supply only goes to minimum 3,16v. I use voltage divider.
Not sure what you mean. The battery goes to the coil which goes to the transistor. The rapid on-off action of the transistor causes the magnetic field to collapse, inducing a voltage of around 110VPP. Now the current is very small, causing it to off of a nearly dead battery.
how to convert 1.5 volt battery to 5volts output using that toroid. and how long the battery last when using it.. i am just wondering to make an lm386 amplifier powered by that toroid
You would have to build a rectifier circuit I think because this circuit is putting out ac, but because it is oscillating so fast, the led appears to be on.
ZooRatedProductions Does it really put out AC voltage? This is good for my purpose of the Joule Thief. I need to raise up the USB's 5V to 9V. I would just have to play with toroids to get the voltage I want. Nice video and explanation :D P.S. Subbed ;)
When I tested it with a scope it was saying around 100 volts ac. This is with barely any current though. The reason that it lights the led is because of the speed of oscillation of the magnetic field collapsing inducing a voltage.
Glad I found this video again. I followed your instructions exactly, about 10 dozen times. Not one time did this circuit do a thing. I even tried setting up the torroid transformers differently, no change. I know not every way I set it up was wrong, there's only a small number of ways to connect the transformers. If this really works, I should have got it to work just through trial and error. If it does work, I would like to know if you would make and sell me about 4 of them for $50
Were you using the exact same parts. Also the torroid is a tricky thing to get right. If you wound it yourself, it may not be tight enough or enough winds. You could also try to find one already made like in a junk computer power supply. I have had this problem making this video actually. I put everything together and it didn't work. So I had to make the video all over again.
Wassup,i have your problem for a long time because every time i was make a mistake,and that mistake it was the windings from the toroid core wich has to be at least 10 turns biflar,after you do this chechk
If is still not working try to look at your transistor pin out confoguration,because if you use a diffrent npn transistor it woud have a diffrent configuration of the base,collector and emitter...good luck...for me the mistake was my toroid ...see what it's yours...
I thought everthing was ok..after I made this circuit..but my transistor (2n2222a) is getting very hot..while Im using 3 volts....not as bad with 1.2 volts..what do you think...??
Thanks for your explanation. I want to make this circuit. Please let me know the materials. What is the blue thing? * I dictated from your explanation about material 1) Ferrite core 2) Transistor 3) Resistance 200Ω 4) ???(blue thing) --- perhaps adjustable resistance? 5) LED 6) some Jumper wires (middle & small size) 7) AA cell in case8) Bread board
The blue thing is a 10kΩ potentiometer (i.e. variable resistor). You could probably obtain a similiar part using one of the following urls: 10KΩ potentiometer: - www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2118791_-1 - octopart.com/3310y-001-103l-bourns-578527 - solarbotics.com/product/rt10k_t/ - www.tme.eu/en/details/3310c-001-103l/cond-plastic-single-turn-axial-pot/bourns/#
Not sure if you can run a router like this. I wonder if this would work by taking two double A batteries in series on the input and setting the output voltage for your router specs. amzn.to/1U8yARq
Jeronimo Murruni I tried it and got 10v from a 5v source, but the transistor heats up fairly fast, what's the simplest way for me to fix that problem (if it involves a heat sink I don't have thermal paste).
+badley wrong That seems awesome with the two of them in parallel. I'll have to try that some time. Also powering it from pencil seems really interesting.
wils35 Graphene is the future... 1 atom thick layer of graphite. Fast charging, slow discharging, can be used as batteries and/or super capacitors, and it can store a heck of a lot of computer data. Graphites conductive capacity as well as its ability to be a resistor can possibly reduce most computer parts to just graphite.
Cats can be little fuzzy balls of static electricity..... Cant hurt to add some form of earthing mat to the entrance to the room lol. Actually it can help the cat too... One of mine sometimes get epileptic fits (like maybe once a year max) due to just grounding itself through its head. static electricity can do that to a cats brain... and its not pretty or nice... he tends to jerk around and I worry he will injure himself so I usually grab him and hold him down with a towel... and there is usually involuntary urination involved so invariably I have to give him a bath (not popular... not popular at all...) and he get confused a few minutes after not recognizing me or his brother for a while.. (cat brain rebooting I guess) So a safe way of earthing the kitty can save both electronic components and the poor cat :p (at least long haired ultra fluffy ones..) (incidentally cats that have more frequent epileptic fits should be taken to a Vet as there may be some more serious issue that has to be treated)
I understand, but the potentiometer IS a resistor, after all, so doesn't it prevent the short? Anyway, the 200Ohm resistor doesn't effect the circuit's functionality, obviously. I just like keeping things as simple as possible so I stick with just pots alone.
Lunartrek I do understand but in testing with this circuit, I was just using the pot alone and when it was anywhere from 0-200 ohms it was cutting out and not working for me. This could be a faulty transistor or something with the toriod.
ZooRatedProductions I get it. So you just made 200Ohms your baseline and used the pot to fine-tune the circuit. Makes good sense. Anyway, it was a fun video.
Also why didn't you just put the LEDs on the reverse side of that prefboard then you could have gotten an enclosure for it later and have the LEDs stick out of some carefully drilled holes :p
+Rich Gordon This one was already wound. It is difficult to get it right so that it is efficient. In the video I have linked th-cam.com/video/0GVLnyTdqkg/w-d-xo.html you can see his diagram of how it is wound.
There are two different spellings for that word. Some Europeans spell it as aluminium. In America, we spell it as aluminum--which is part of the reason that we pronounce that word differently. :)
T.P. Pansas the purpose of this device is to take the small voltage coming out of a dead AA battery, and boosting it to run some leds. you could have a that is considered dead in a tv remote, still work in this circuit for at least a couple of hours.
I finally got all the parts. So far I finished two circuits of the first part of your video. Both work well with 1K resistor not 220 Ohm.. I also inserted 1,2&3 LED's. Everything is great and functions on 0.8 volts ( dead battery AA)or less. Next will be using a solder board. Again thank you for your video.

I suck at these things ...
and even I understand this ...
thanks man ...this is perfect ..
thank you for this. I needed an explanation that took its time and went into detail. I appreciate your hooking up the battery at the end. peace
Thanks for the knowledge. Really appreciate it!
Hi ! Really great tutorial. Thx. But is your toroid iron powder or a metal core?
Your video is amazing. Thank you. Many are asking if you could give advice or make a video to make this Toroid or where you bought from. Again,thanks.
Any toroid with two windings of 20 turns should work fine, This circuit isn't all that fussy about component values. It might be better to use a larger transistor if you want to run lots of LEDs.
What is the AC to DC variable power supply brand name/model you are using here?
Do you know about crystal batteries? I have something I would like to see you make if your interested.
Keep with good work and show how the things are working with no frauds great job!
How do you know which holes to stick the components in ? I am a newbee and just purchased a breadboard with jumpers from Rad. Shk. But it did not come with instructions ! Where can I find out how to use it ? Thanks (too many holes )
where did you get the toroid core and what size is it?
Thanks for the video and the presentation. This drives most viewers including me to try it provided parts can be easily acquired. Will save this video for future reference.
Karim Ismail glad it helped.
hey please tell me what camera are you using . does it cost 1 billion $
I have a ferrite toroid magnet will that make a good joule thief or does it have to be plain ferrite without any magnetism?
Hey! i'm trying to build one of this connected to a 1.5V AA battery. Could you tell me for how long would the LED's be on for just with the AA battery?
MAN you are a teacher, You should do this stuff for living, the way you do it simple step by step that is what I was looking and I had been looking weeks now, and now I got what I want to see so badly, You should do DVD's with difference projects on it, I sure would buy your DVD's for sure, It is good that you do it, it helps some many people that are in to difference projects and you are a smart guy, it is you are doing it for free and thank you so much for shearing it. Thank you from Calgary,
P.S. I have birds, and I'm using just the timers on the light, But I want something that would mind the lights from full to dark in one hour in the evening, And than in the Morning from no lights to lights on with in one hour. Do you think you could make something that I could use for that? even if I had to have it hooked up to a computer?

Hello, you will kindly Put you the list of materials that would be used to make it. From already thank you very much. (excuse my English)
what is the brand of that regulated variable power supply?
I like this !
I tried to find a power supply like yours, but all the xp15's I found did not have a digital display.......did you add this feature ?
+qwertyqwerty1955 yes I added that to it. This is the one I used amzn.to/1QFgRCQ
+ZooRatedProductions did you have to use an external power supply (battery) in order to read the very low voltages ?
no you dont
That's a great Toroid core. Did you make the base for it?? I don't see one like that via the link to Banggood you provided in comments below !! All of theirs just have open leads at the bottom of the windings. I'd like to get/make a few of those !!!
I found this one in a computer power supply. Cant find anything close to it online.
Thanks !! I think you got lucky to find one in a commercial power supply that is plug compatible with breadboard spacing !!
Also is produced small DC to DC step up converters, sim card size. I think more efficiency.
I built the same thing, it didnt work. Is transistor has to be certain pick up?
does this work using mini windmill from a small dc motor?
as a source.
what did you take appart to get that choke
Great video! How long can a AA battery last when powering these lights? Better still what is the current drawn from your power supply?
Have you done any measurements of efficiency ? Power in power out ? How lossy are these systems ?
I have not
ZooRatedProductions Thank you . I , with finger in the wind knowledge , would suggest , they would be found , notably lossy , as it is a brew of resistance - heat loss & collapsing magnetic field ...... but I not suggesting it can be bettered ....... without more up front cost & madness . I think the term that you comes to hand , would be cost effective .
the only thing that I measured was the voltage across the leds and it was 110vpp. it didn't make any sense to me or my professors.
I think this happened because when the magnetic field drops out, it creates a voltage spike and that is what the scope was reading.
ZooRatedProductions That ' s the trouble with instrumentation , it is sometimes more difficult to understand what it reads , than if the reading is correct . The transitory becoming the definitive .
could you use multiple joule thiefs in one circuit? would this increase your voltage output?
Thank you man . very nice. keep on the good work. thumbs up!!

good eats
LMFAO, you said "20 fairoid core" Um dude it's a ferrite core toroid with 20 turns. THe "scream" you hear is the Transistor
Thanks for the video. I build it with your instruction and it works perfekt. I got it work with 0,92v. My supply only goes to minimum 3,16v. I use voltage divider.
How much current does this circuit draw at the voltage you're using?
it draws about 20milliamps
Where can I get that toroid??
Thank you for sharing it. Very interesting.
can i run my wifi router by this ' & if S then what thing i need plzz reply
This is very interesting and informative. Good Job of explaining!
Thank you.
hey zoo, ever thought of making the ferrite core whine as loud as possible?
What is the device you used to control the source voltage? Btw, great video!
Not sure what you mean. The battery goes to the coil which goes to the transistor. The rapid on-off action of the transistor causes the magnetic field to collapse, inducing a voltage of around 110VPP. Now the current is very small, causing it to off of a nearly dead battery.
I meant the device that controlled the current (when you set the input voltage to 1.32 volts)
how to convert 1.5 volt battery to 5volts output using that toroid. and how long the battery last when using it..
i am just wondering to make an lm386 amplifier powered by that toroid

U can tell me which gauge of copper wire is used
I think 22 or 20 gauge. it shouldn't matter what size
Thank bro
I thought everthing was ok..after I made this circuit..but my transistor (2n2222a) is getting very hot..while Im using 3 volts....not as bad with 1.2 volts..what do you think...??
Use a power transistor (2N3055 or any other) with heatsink,
how much current the circuit draw on 1 volt?
Thanks for your explanation. I want to make this circuit.
Please let me know the materials. What is the blue thing?
* I dictated from your explanation about material
1) Ferrite core 2) Transistor 3) Resistance 200Ω

5) LED
6) some Jumper wires (middle & small size)

Such size of toroid can be found on the circuit of induction cooker..
where can i get a ferrite core like that?
+Broccolilover69 www.banggood.com/fr/search/tore.html
Thanks man
You may get such toroid from induction cooker circuit .
Using a bt136 to ac 120v to 160 same?
Will it work in pumping 5v into something like 10v?
Yes, but you don't have to put a high load
Ok
Jeronimo Murruni
I tried it and got 10v from a 5v source, but the transistor heats up fairly fast, what's the simplest way for me to fix that problem (if it involves a heat sink I don't have thermal paste).
5thDragonDreamCaster What transistor did you use?? Tell me the code and i'll find one equivalent, but with more POWER :D
Jeronimo Murruni
Never mind now, I swapped it out for n channel mosfet and it worked fine, but thanks though.
Can it work on a small dc motor
very good dude
UN TRANSISTOR SIMILAR AL QUE TIENE EL CIRCUITO .....XK EN MI AREA NO HAY EL KE TIENE PUESTO.......MUCHAS GRACIAS
If I ever get a 3 d printer I'm going to print the halo pistol and put a led where the laser needs to be
+badley wrong
That seems awesome with the two of them in parallel. I'll have to try that some time. Also powering it from pencil seems really interesting.
that's pretty sweet. if you'd be willing to do a video on that, that would be awesome.
***** You saying about graphite being a good conductor, look up Graphene ;)

Cats can be little fuzzy balls of static electricity.....
Cant hurt to add some form of earthing mat to the entrance to the room lol.
Actually it can help the cat too...
One of mine sometimes get epileptic fits (like maybe once a year max) due to just grounding itself through its head.
static electricity can do that to a cats brain... and its not pretty or nice... he tends to jerk around and I worry he will injure himself so I usually grab him and hold him down with a towel... and there is usually involuntary urination involved so invariably I have to give him a bath (not popular... not popular at all...)
and he get confused a few minutes after not recognizing me or his brother for a while.. (cat brain rebooting I guess)
So a safe way of earthing the kitty can save both electronic components and the poor cat :p (at least long haired ultra fluffy ones..)
(incidentally cats that have more frequent epileptic fits should be taken to a Vet as there may be some more serious issue that has to be treated)
cool vid dude
I would like to posit that, if you have a 10kOmh Potentiometer, you do not need that 200Ohm resistor. Try it, you'll see!
Lunartrek That 200 ohm resistor is so there is not a direct short from the base of the transistor and the core.
I understand, but the potentiometer IS a resistor, after all, so doesn't it prevent the short? Anyway, the 200Ohm resistor doesn't effect the circuit's functionality, obviously. I just like keeping things as simple as possible so I stick with just pots alone.

ZooRatedProductions I get it. So you just made 200Ohms your baseline and used the pot to fine-tune the circuit. Makes good sense. Anyway, it was a fun video.
I would you list the parts needed nice video
Judging by the burn marks and bubbles on your bench, you've pushed components to their extremes quite a few times. Heh heh.
fb314 the bench suffered marks from a soldering iron, and yes the breadboard suffered burns from cranking the power to the max for fun.
very useful.thanks
it very simple step by step I can do it now thanks
just did it. it works great thanks
Yeah, I'm going to do something cool. Also my cat wants to say hi.
Woof
19:19
oops!!!!!!!!!!
Your so cool! No bs legit :p love this vid
2n2222 works great too.
Also why didn't you just put the LEDs on the reverse side of that prefboard then you could have gotten an enclosure for it later and have the LEDs stick out of some carefully drilled holes :p
Can you get rid of that sound so the beeeeeeeeeeeeeeeep and if how
Great.please provide a schematic diagram.
Why do all the joule thief experts never go into detail about how to wind the torrid?
+Rich Gordon This one was already wound. It is difficult to get it right so that it is efficient. In the video I have linked th-cam.com/video/0GVLnyTdqkg/w-d-xo.html you can see his diagram of how it is wound.
No problem I found a video that provides the details
david spade is that you?
Congratulations !
I don't understand why people like you have to come on and post first just because you were the first person to post on his video.
Ac 110v coils same
Did anyone else notice that this is being narrated by David Spade? lol
Finch ?
plese send circuit
Dx.com for parts huh
nice :)
Describe the transistor. NPN?
Yes, this is a NPN type transistor.
Lacking on the explanation side, but informative nonetheless.
Oh no -not another one who says "sodder". I think he means SOLDER -you know- a bit like soldier- Sodder off.......
Fyi... It is phonetically pronounced "sod-er"--according to the dictionary.
Hahaha annoying aint it. Sodder it good. And for you yanks it Soul der.
mart fart
No yanks should pronounce it as sold-er, as our dictionary does not show to pronounce it that way.
A B Haha never mind. Aluminium.
There are two different spellings for that word. Some Europeans spell it as aluminium. In America, we spell it as aluminum--which is part of the reason that we pronounce that word differently. :)

I hooked up a nine volt
what was the voltage of the output?
I'd forgot lol
lmao
So what is the purpose of the joule robber
T.P. Pansas the purpose of this device is to take the small voltage coming out of a dead AA battery, and boosting it to run some leds. you could have a that is considered dead in a tv remote, still work in this circuit for at least a couple of hours.
now put solar panels on the back silly

I finally got all the parts. So far I finished two circuits of the first part of your video. Both work well with 1K resistor not 220 Ohm.. I also inserted 1,2&3 LED's. Everything is great and functions on 0.8 volts ( dead battery AA)or less. Next will be using a solder board. Again thank you for your video.
