How to Make a joule thief circuit to extract battery power

Apr 10, 2008 11:23 PM

This week, Windell Oskay of Evil Mad Scientist Laboratories joins me to teach you how to make a super clever little circuit called the Joule Thief! The Joule Thief allows you to squeeze the life out of what most people think of as "dead" batteries!

We were inspired by Big Clive to make this project and it's the perfect platform for a flashlight, book reading light, or really just something you should make to g et more use out of your batteries!

The next big software update for iPhone is coming sometime in April and will include a Food section in Apple News+, an easy-to-miss new Ambient Music app, Priority Notifications thanks to Apple Intelligence, and updates to apps like Mail, Photos, Podcasts, and Safari. See what else is coming to your iPhone with the iOS 18.4 update.
