What is special is the use of a standard inductor instead of one with 3 connections that you need to wind yourself.\n\nA joule thief is a circuit able to use the very last electron from a 1.5V battery. 'empty' AA cells contain enough energie to light a white LED for over a week.\n\nThe schematic made in LTSpice.\n\n![](white%20led%20circuit%20joule%20thief%20schematic.png)\n\nHigh enough voltage to light a white LED.\n\n![](white%20led%20circuit%20joule%20thief%20waveform.png)\n\nThe pcb that is still in use in 2021.\n\n![](white-led-circuit-joule-thief-pcb.jpg)\n\n![](white-led-circuit-joule-thief-detail.jpg)\n\n[![License](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fatoomnetmarc%2Fjoule-thief","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fatoomnetmarc%2Fjoule-thief","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fatoomnetmarc%2Fjoule-thief/lists"}
