Modified Wireless Power Transmitter.

Подробнее о видео

In this video, I show how I upgraded a basic Joule Thief circuit into a wireless power transmitter using just a 1.5V AA battery!

The original design used a ferrite toroid core to boost voltage for a standard LED. But in the upgraded version, I added a 15-turn air-core coil connected to the feedback winding (L2), allowing energy to transmit wirelessly and light up an LED on a nearby receiver coil!
