3 Best Joule Thief Circuits

Technically it may seem impossible to illuminate a 3.3V LED with a 1.5V source, but the amazing concept of joule thief makes this look so easy and effective, and virtually unbelievable. Moreover the circuit additionally makes sure that not a single drop of “joule” is left unused in the cell. A joule thief circuit is … Read more3 Best Joule Thief Circuits

Make this Buck Converter Using Arduino

In this project we are going to step down 12v D.C to any D.C value between 2 and 11volts. The circuit which steps down the D.C voltage is known as buck converter. The output voltage or step down voltage needed is controlled using a potentiometer connected to arduino. By Ankit Negi INTRODUCTION TO CONVERTERS: There … Read moreMake this Buck Converter Using Arduino
