How Does the Joules Thief ⚡Free Energy Work? 

NOTE: At the end of the video it says that we can change the *Amps* of the inductor to modify the behaviour of the circuit, this is wrong, it should say *Henrys*. Not sure how this translation error happened, in the original video and script it says Henrys. I will check in to this to avoid similar problems in the future 😁 by the way, new video on how X-Ray works is coming soon :) - EP -

It's not free energy, it is raising the voltage but reducing the duty cycle. So instead of steady flow of 1 volt, it will create pulses of 2 volt at 50% duty cycle (i.e. remaining on for only 50% of time). Free energy is when u r creating more energy than u r putting into the system, that is both voltage and current should increase.

Very well explained. Simple. Thank You!

Wow thank you. It is really the best explanation ever.

Thank you for the spectacular explanation of materials and visual of operation

THIS VIDEO HELPED ME UNDERSTAND WORKING OF POWER BANK ALSO

brilliant video

Many products will reject a battery at 1.3 Volts and say "low battery". This is like putting 15 gallons of gasoline in our car and have it show empty when we use the first 2 gallons. The Joule Thief helps us get back what would be wasted.

Finely!!

I doubt anyone understands this but a jewel thief is more or less a Tesla coil. Although tesla used the bifiler coil as a capacitor. More so if you at a capacitor with the same Capacity as the inductor in series it becomes a High frequency pulse amplifier.

I know motorcycle ignition coil have similar mechanism, but if I wanna use it to deplete my motorcycle battery, will I have to use additional components?

Thanks

Please requesting you make a video on digital vernier calipers

I built a couple of those but still dont fully understand them. I even looked at them with an oscilloscope and I see what happens but it still puzzles me a bit. I dont really understand why the voltage goes higher and higher. When the magnetic field of the coil collapses it induces the high voltage. Then the transistor closes connection so the voltage can only go through the LED. But THEN the transistor switches on again.. Why doesnt the voltage just go to the negative terminal of the battery ? Or will the voltage induced be in series with the battery ?? Oh maybe I got it ?? Is the induced voltage in series with the battery over and over, thus increasing until it can flow through the LED (and being capped by the led ? Lol if that is correct just writing this comment made me understand it. I'll check to verify with my oscilloscope. PS: Thanks for the video ☺ I can clearly see that you put lots of effort in it :) awesome animations and explanation. Still hard to get your head around.

Thanks.

Great video. Right at the end "a few microAmps or MilliAmps" should be microHenries or milliHenries.

The pinout of TO220 BJT's is incorrectly described in this video.

"How Does the Joules Thief ⚡Free Energy Work?" it's not free energy...

Current doesn't flow Positive to Negative in that direction. How does any of this make sense?

The inductor is rated in terms of Henrys, notamps.

How does an electronic anti-drone guns work?

Invented by Big Clive. He has a yt channel apparently.

🙏🏼🇧🇷🌱👍

not enough power :c what a mood haha

Ok all the super smart people here 2 questions, #1 if you increased the amount of coils and you wrap them to where there is multiple levels of coils stacked on top of each other does that mean that there would be more power produced? #2 if you take away the LED bulb and instead run it straight to the battery and you have a battery that is capable of recharging would this in turn recharge the battery? And I guess I have a 3 question how does a rechargeable battery work opposed to an alkaline battery? Why are you not able to recharge alkaline batteries? Thanks ahead to anyone that can comment or answer these questions

Interesting animation, but you are wrong with your placement of the resistor and you missed key Insights ------> ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ugPCH_3AIUQ.html

This is a nice explanation except you explained the transformer completely wrong. It is a center tapped inductor, not two opposing coils. The center tap is connected to the positive battery terminal.

Boop

Makes sense why it's used to scavenge static from the air.

Hi VirtualBrain, there's a channel called "鹰眼科普" that steals people's works and re-upload them. You are among the victims. This video is copied and pasted under a title "他就像電路中的資本家，神奇的焦耳小偷電路工作原理". You probably can report them to YT and get it taken down. You may find multiple of your works on their page, too.
