Problem is since the output voltage is completely unregulated and there's nothing in the way of charge termination you might end up popping your batteries. If you build this circuit keep an eye on the battery voltages and their temperature.
Well said, you really want to keep an eye on it while charging. I made a charger based on this once with all scrap parts before I bought a smart charger for my Eneloop Ni-Mh I bought for my camera. I used a decently sized joule thief with 4 windings: power, feedback, output and supply. The supply was half wave rectified and capacitor filtered to reference the switching circuit with 5V from a Zener diode. It trickle charged in separately transistor limited channels at about C/8 so it didn't have a chance to overcharge. I added a switch to change the base resistance for different amounts of batteries up to 4 and I added a simple voltage based cutoff that turned off at about 1.45V. It consisted of a transistor controlling the positive flow to the battery, bypassed for a reason I will state later. It's base was floating between a limited reference to the "supply" output positive and the battery's negative connection. It only used resistors, when the battery had enough negative potential it would turn off the NPN transistor. The bypass allowed 1mA to continue charging when done, completing the circuit and allowing the negative connection to hold the transistor off. When all batteries were done and the output voltage of the "output" coil voltage spiked up high it would light a neon indicator and feed the 3.5-6kHz sine into a piezo, which was decently loud. I still keep it for solar panels and such. I really thought it through, and it worked great. Makes a nice emergency charger, but is a bit over complicated. Mess of free formed (PCBless curcuit) inside a tiny plastic cube that was filled with with hot glue to encapsulate and protect it from bending and shorting.
I thought that the batteries would stop charging once the voltage of the batteries equals the voltage of the power source. Can someone explain, in simple terms, why I'm incorrect?
***** True. But if voltage source produces 1.5V, this circuit produces at least 10-16V alternating DC on the output. It's average voltage will be maybe 3-5V or so at that input level, but the absolute peak to peak voltage can be several times that.
@@J2897Tutorials Your right, that's why there is no explaination. Also the joule thief boosts voltage at the expense of current, so the batteries will not recieve a correct charge and will poop out very soon.l
Very helpful! I searched all the parts and it was too expensive, so I went to the local walmart and bought the energizer battery charger, took it apart and put it all together. It works great!
I remember seeing a circuit like this in an electronics book years ago back before the internet was around. The main difference was a transformer was used to step up the oscillated DC voltage and then ran through a bridge rectifier.
I have been experimenting with charging two 1.5v AA batteries from 4 small ,parallel wired solar panels all day.At the moment I have them joined up to a jewel thief , the volts seem to be creeping up slowly,even in quite low light.I have been looking for a way to improve the circuit,and yours looks worth a try.
Instead of winding a coil you can use a pair of through-hole or surface mount inductors (look like resistors) & dirt cheap, For even smaller size and better control you can use a dedicated boost converter chip, no transistor, and just one inductor since it will pulse by itself. Look inside a cheap solar powered garden light to see how this is done.
The cap after the diode isn't needed. In fact some think that a high frequency changing a battery helps batteries that are getting where they don't want to take a chance anymore because it can clean the surface of the inside parts, but I have not done any tests
In the before schematic shouldn't the 1k resistor be between the transistor and toroid instead of being up there, or it doesn't matter as long as it's in-line with them?
Hi, What type of cap did you use for C-2 your output and what type of rectifier diode D-2 . I am going to attempt doing this of the glass of a USB plasma ball. I know it sounds crazy and I am sure a lot of people would ask me why do I want to do that, but I have found that there is a lot of power coming from the glass of a USB plasma ball and just for fun I want to find different ways to turn it into usable energy. I am sure that I will have to rectify the imput some since the 20 KHz frequency coming from the glass is like a very strong radio signal but like I said fun. I will share back on my results. Thank you.
I have a small array of solar cells that produce around 2.5 v max. I want to be able to charge either a phone or battery bank, both of which draw 1A and 5v. Is there anyway this is possible as i built the circuit but my output voltage drops to basically 0v when the phone or power bank is hooked up. (It produces around 7V when nothing is hooked up to the output.)
Make what u have done is right i love it but i think the schematic circuit u provided is wrong i have tried a lot but it does not work out for me n i did not get what the two dots mean near torroid
hook a joule thief to a speaker... any sound you make in the room at all will light an LED fully... lol.. use a capacitor to build up a charge on the output to help light an LED better.. Pretty close to free energy but technically not free. as the dust particles and air moving around in the room will make tiny vibrations touching the speaker. causing the tiniest voltage to be created..
Hey , its great I thought about this project why not use a single AA battery to charge the two AA batteries . and then use the recharged battery to again recharge the battery. Sorry if I am wrong feel free to answer.
Wrong indeed... That would be perpetual, and that is impossible... It's like saying, let's get one cup of water to fill two other cups, then use those cups to fill more... See? Eventually, the amount of water in each cup would be less than a ml... Same with batteries...
Although you did not show it practically , doesn't the coils have to be connected in opposite directions ? IE. The start of the orange wire is connected to the last( end ) winding of the green wire so you end up with three connections: orange out ( last tail)...? then orange start soldered to green last tail ( end )....and the third connection is the start of the green wire. The schematic does show the coils wound in opposite direction with the dots
Nope! This type of circuit is used for many normal applications. For example those electric bug zappers, or the energy saving light bulbs, or those cheap bicycle LED lights. It's called a joule thief because you can take a battery that seems to be drained, but as long as it contains a small charge in it it can be used for a low power application such as an L.E.D. light, or to partially charge another battery. In other words, with this joule thief circuit you can drain the last remaining joules from a seemingly empty battery and the circuit will convert that energy to such a level that it still can be used. The initial input power source doesn't have to be a battery, a small solar panel or an earth battery, or a fruit battery are possible energy sources as well. It is NOT possible to give a completely drained battery a full charge with a single seemingly drained battery because it only charges partially until the initial input power source for the circuit has no more joules or energy left in it. In order to get a full charge you would need several seemingly drained batteries as the initial input power source for the circuit. Batteries with not enough charge left in it in order to operate a digital camera or a computer mouse can still be used with this joule thief circuit. So the conclusion is that the output measured in joules is NOT greater or more then the input, so it is NOT an over unity or free energy device. It's nothing more then a simple, efficient and fun circuit to play with because it is easy, cheap and harmless.
i get infinite energy from my outlets at home. Too bad it comes with a cost...so the only thing i have to find is someone who is willing to pay for it... probably a lot easier than making a Perpetuum mobile with free energy...
Infinite? One scenario- your power company goes down... Poof, not so infinite anymore. And this is not a perpetual mobile, whatever you mean by "mobile", as you might mean "module", as it only extracts energy, not give you free energy...

Stored Power = Power * Time Power = Volts * Amps If you need 230 Volts and 4 Amps to use your computer for 1 hour you would need to store 920Wh. one car battery has about 432Wh. and when input Power >= output Power the battery would need to give 76,5 Amps. but only a few strong wires can lead that mcuh power. and the battery would explode. if you would use 19 batterys you would have enuoth voltage to run you pc. and it would last for about 28 Days. But to run your whole house this would only last for a few horus. So you still can't get free energy. But if you do it to generate enegry out of nothing you would make good as everything we know about physics wrong

This sounds stupid but..... Couldn't you use a dead rechargeable battery to charge another dead one and than they switch places, two fully charged ones from 2 dead ones?
Hi sir, I'm your biggest fan, I wanna purchase rc parts from your end to my rc plane, can you sell me the parts below with less rate or used parts....?? 1. Rc motor+esc+propeller 2. 3ch Receiver+ 3ch transmitter
go to Flitetest on youtube of hobby king will also sell you some cheap part You are going to want more like 5 or 6 channels incase you want to upgrade with 3 channels all you get is throttle aileron and rudder you are going to want elevator when you become more advanced
Ah yes, charge a battery with a device that doesn't control voltage on the charging side. Then you wonder why your batteries go dead entirely or stop being able to keep their charge. It's ok if you use this kind of "booster circuit" to drive a LED, hey, it's only a 1$ LED you break at worst. Trying to charge a battery, could mean an exploding battery.

insAneTunA I realize that, I never said it was magic. Over unity or energy destruction results can be achieved through 2 ways mathematically: 1) You vary the resistance in respect to time 2) You vary the capacitance in respect to time (in real life, over unity can be achieved in millions of different ways, electrets, Moray Generator, Hendershot Generator, bi-toroid transformer, Stan Meyer's EPG, Steven Mark's TPU, etc, etc.)
It sounds more like "desperate energy" since you're trying to grab every last joule from a seemingly dead battery. It makes sense though, why waste that remaining energy when it can still be used.
Notice he doesn't show the batteries being charged. This channel gets a thumbs down from me because it is a fraud and is just clickbait, to get revenue from ads.

what function do capacitors play in that circuit?
They help to stabilize the voltage going to the battery and into the joule thief
I think the one on the left is for moderating and extending the output pulse. It works like the filter capacitor in an AC to DC circuit.
I can't really manage to start with pin solar cells, what I've tried is that it requires too much current, i.e. mA.

Well, it isn't. This type of circuit is used for many normal applications. For example those electric bug zappers, or the energy saving light bulbs, or those cheap bicycle LED lights. It's called a joule thief because you can take a battery that seems to be drained, but as long as it contains a small charge in it it can be used for a low power application such as an L.E.D. light, or to partially charge another battery. In other words, with this joule thief circuit you can drain the last remaining joules from a seemingly empty battery and the circuit will convert that energy to such a level that it still can be used. The initial input power source doesn't have to be a battery, a small solar panel or an earth battery, or a fruit battery are possible energy sources as well.
It is NOT possible to give a completely drained battery a full charge with a single seemingly drained battery because it only charges partially until the initial input power source for the circuit has no more joules or energy left in it. In order to get a full charge you would need several seemingly drained batteries as the initial input power source for the circuit. Batteries with not enough charge left in it in order to operate a digital camera or a computer mouse can still be used with this joule thief circuit.
So the conclusion is that the output measured in joules is NOT greater or more then the input, so it is NOT an over unity or free energy device. It's nothing more then a simple, efficient and fun circuit to play with because it is easy, cheap and harmless.
This is free energy though. :P

No, it isn't, it is not a magical energy generator. It converts existing energy, that's all.
insAneTunA I realize that, I never said it was magic.
Over unity or energy destruction results can be achieved through 2 ways mathematically:
1) You vary the resistance in respect to time
2) You vary the capacitance in respect to time
(in real life, over unity can be achieved in millions of different ways, electrets, Moray Generator, Hendershot Generator, bi-toroid transformer, Stan Meyer's EPG, Steven Mark's TPU, etc, etc.)
It sounds more like "desperate energy" since you're trying to grab every last joule from a seemingly dead battery. It makes sense though, why waste that remaining energy when it can still be used.
Notice he doesn't show the batteries being charged. This channel gets a thumbs down from me because it is a fraud and is just clickbait, to get revenue from ads.
