Joule thief circuit is famous among electronics enthusiasts. It has many implementations but probably most common is very minimalist voltage booster based on In simulation file we .. -
Here is a totally different take on the Joule Thief (JT) circuit commonly found in garden lights. Instead of charging a 1.2v battery directly from the solar cell and converting the .. -
Today I am showing you how to make a very simple joule thief. A joule thief has many applications, the best gadget that I made with was a Water Powered Lamp, soon Im going to post on .. -
So the title has a lot of words in it, but that is because this instructable combines many ideas from many sources. The general idea stemmed from robomaniacs Desktop energy seed lamp.. -
Yep, no transformer and no hard to get IC. But two transistors and other parts are required. I actually found this circuit by accident while roaming Colin Mitchells Talking Electronics.. -
The post explains a simple 1 watt LED driver circuit using a single 1.5 V penlight cell through joule thief concept. The coil may be wound over a T13 torroidal ferrite core using a 0.2mm.. -
This is probably the 1001 flashlight with a joule thief, but then again this is mine :) I used a pen style flashlight from duracell. It has a 2.2 volt lamp and two AAA batteries... -
I have many used batteries around. Remote controls, cameras, many electronic gadgets all use batteries, mostly AA size. I always felt guilty for throwing away the used batteries... -
A high power joule thief circuit is explained in the following post which can constructed by any new hobbyist. Here is the simplified drawing I biult the radiant joule thief battery charger.. -
Afraid of the dark? Built a simple Joule Thief circuit and would like to go further? Just want to have a cool blue light to show off to friends? Let me present the Joule Thief 10x10 LED.. -
Investigating a Paradox: Recently, I saw an energy saving LED flashlight for sale and it only used one 1.5 volt battery. I purchased this light and took it apart expecting to find a .. -
You are now showing a 1n4148 diode, and a 1 meg resistor. My question is: How can you can light the led(s) off of a 1.5 volt battery. That additional coil L3, I am not sure how it affects.. -
The Joule Thief is such an easy and simple device, but what it does is amazing. It can use a battery that is not usable in any other electronic device and It is super simple to make on a.. -
Retired Physics Professor, Steven E. Jones is working on a simple overunity circuit that he has seen go as high as 20 times overunity. The circuit is a derivation of the Joule Thief.. -
Battery Vampires are circuits designed to suck as much energy as possible out of batteries/cells. They are not regulated drivers they are a boost circuit create a higher voltage on .. -
You would think that given how many flashlight projects I do that I actually own a lot of lights. I can change the inductor to adjust the current setpoint, but the overall current.. -
The Joule thief… yes, It’s been discussed here before, and in many other places, so not something really new, but the twist is that I took the concept and it had lots of good .. -
Presented here is a significant step forward in simple, cheep, and efficient boost converter design. So to make an effective design, we must convert the current to voltage as .. -
I wanted to make 3v to 1000 volts inverter circuit. I already soldered circuit but it doesnt work. I wanted experts to look for errors in my circuit. Also I dont know if I made .. -
I have followed some threads on ringer and have seen many variants, specially the transformer used like aircore and stepdown transformer types. Some similar circuits : 1)12V-to-120V.. -
R1, D3 and C1 are optional! You just need one LED. If it does not work, try to switch the LED polarity. I first tried a single 555 CCT (CirCuiT). I was annoyed by the huge current consumption... -
A low power, long life LED flashlight circuit. Electronic Design proposed a simple circuit to resolve this in a recent article. The front end of their circuit draws less than a milliamp of extra current... -

Well, this particular circuit is called the Joule Thief, and for those of you that arent familiar with the circuit, here is an image of it... -
Joule theif circuit and videos with circuit diagrams and explanations... -
The post discusses a joule thief circuit which drives and illuminates four 1 watt LEDs using just a single 1.5V pencil cell... -
When working with these circuits, I bought a light-meter to take the guesswork out of assessing light levels as the human eye is very bad at doing that... -
Blue and white LED drivers using joule thief circuit has been covered in this post, lets learn more. The circuit may be simulated with the following points.. -
In this example we have the PWM (pulse-width modulation) output of the microcontroller driving a Joule Thief style voltage booster to run the white LED... -
Joule thieves arent just for lighting plain old LEDs!. Attiny joule thief neopixel.. -

The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
