Handmade toroidal inductor for "Joule Thief" circuit.
To make one of these, you need to start with a toroid, which is a piece of ferrite (Iron) shaped like a doughnut. You will also need wire. I used 0.3mm coated copper wire.
My first "Joule Thief" powering 2 white LED's with a single, "dead" AA battery
I’ve been wanting to do this for many months. I finally got some scrap parts together and made my first Joule Thief. This circuit milks the last bits of energy out of your “dead” batteries.
Circuit diagram, video, pictures, and observations included…
I tried making the Joule Thief as shown in a Make video from makezine.com.
