Flashlight Circuit with Long Backup and High Efficiency

Last Updated on July 24, 2024 by Swagatam 2 Comments

There are two main advantages of this highly efficient flashlight circuit with long backup. Firstly, it uses only a single 1.5V AAA cell and illuminates a 3.3V LED. Secondly, the 1.5V cell is consumed by the LED until there’s virtually no charge left in it. Due to these features, this flashlight is able to last […]

Last Updated on November 9, 2024 by Swagatam 14 Comments

torchdia

In this article I will show how to construct a Faraday flashlight circuit using only a coil/magnet assembly which requires no battery. It’s not free energy, but it converts oscillatory motion to electricity, which can power the flashlight for a couple of minutes. This flashlight will be useful in emergency situations where no access to […]
