We have out of state relatives visiting this week, so I grabbed the Joule Thief that I made a long time ago just to play with it for a short while. I took a relatively dead battery, 1.25 volts, and connected the JT output to a 1500 uF capacitor. I was surprised at how fast it charged it. I can see why people get ...

People have asked me if I think the Joule Thief produces excess energy. My answer is --> No, I have not seen or tested any Joule Thief that produces excess energy. I've seen countless Joule Thief videos, and I spend a great deal of time replicating the best Joule Thief claim, a claim by the anonymous user name ...

Yesterday I tested gadgetmall (Albert) Joule Thief circuit. I used a AAA NiMH 700mAh battery as the source connected to Albert's circuit, which in turn charges a BCAP0650 ultracapacitor (UC). The UC started at 1.130 volts. The AA battery was charged. The experiment ended with the AAA at 0.491V, and the UC at 1.313V. ...

Here's my results of testing gadgetmalls circuit, or at least the closest I can presently get to it. I don't have his toroid, but I'm using a good toroid with high permeability & similar size that he describes. This method consist of using a resistor for the load, and measuring the resistors temperature, which ...

A user by the name of gadgetmall at overunity.com has made some huge claims. He claims his modified Joule Thief circuit can make a AA battery fully charge a 650F Maxwell boostcap, where the AA battery voltage only drops by some microvolts. So I ordered one 650F Maxwell boostcap, $30 + $9 S&H. When the ...
