“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. You most commonly see this …
“For those who have never heard the term, make it easy for me here and quote Wikipedia : “As Joule thief (German Joule-thief or energy thief) refers to a discrete electronic circuit in electronics, the electrical DC voltage in a higher …
“LED filaments are thin, stick like LEDs. They are used in many Edison bulb look-a-like LED bulbs.Each of those thin sticks contain many - 20 to 30 LEDs connected in series. So they are quite bright and energy efficient, however …
“A minimalist 1.5V coin cell led tree with all components and power source confined within a mini breadboard. This is a holiday project targeting the 2017 December HackaDay coin cell challenge.The objective is to employ a 1.5V …
“This LED flasher circuit will run for 10 years on a single 1.5V AA cell. Circuit is basically a “gated” blocking oscillator (joule thief) . IC1 CD4001 requires 3V and will not run from 1.5V (AA cell) when first …
“Hey everyone, getting busy with your DIY projects? If your projects are LED based, you will require a power supply that is quite efficient and make sure the circuit consumes low power. A joule thief can be a solution. Only …
“Hey nice to see you again guys! Now I’m back with another instructable. I shall teach you how to make a diy joule thief. This is one of the easiest way to make a joule thief and the most …
“Did you have problems winding the toroidal transformer of a regular joule thief? If so then this instructable is for you! And if not it is also an interesting circuit to see. In this instructable I will show you how …
“This idea appeared to me by coincidence and I thought I’ve ever done no more Instructable and that’s why I have this idea Documented have fun and reverse engineering or reading :)”
“Joule Thief allows to use almost all of the energy of a single cell or a single cell battery. Thus, the circuit Joule Thief permits to increase the voltage of the source (battery, battery) above the minimum voltage required to …
