This is my new and improved earth battery running 4 ultra bright 10mm 28000 MCD LEDs. I am using a standard Joule Thief circuit wound (bifilar) on a ferrite toroid this time. An N3904…
Combining present circuit ideas with those of the recent video by PMMG4HYBRID, this video demonstrates a peculiar phenomenon…that of a li-ion cell charging back up after moderate usage. Whether cell chemistry, radiant conditioning or…
This shows a battery that uses calcium cloride to draw moisture out of the air and help run a copper and magnesium battery. I also show a simple Joule Thief circuit that uses the…
This is my earth battery running a 48″ (40 watt) florescent tube. It is not at full brightness but it is lit and lit pretty well. It is much brighter than it appears on…
I am replicating a test I saw on the net where folks listened to their Joule thief circuits using an AM radio. Yes, this is still the same old AA battery as I used in all of my previous tests. Here I test a regular Joule Thief toroid circuit and the Fu…
This is a Joule Thief Flashlight. I simply modified a cheap 5 super bright LED flashlight that ran on 3 AA batteries by gutting it and using a simple Joule thief circuit which now…
Q1 and Q2 oscillations in the Rosemary Ainslie NERD claimed overunity circuit. They have nothing whatever to do with function generator operation, other than depending on it as a power supply. Erratum: Of course…
This is a 60 watt equiv. LED bulb that uses 9.5 watts when driven by the mains. It is rated at 800 lumens and is the best LED bulb I have tested to date….
An example of wireless electricity experiments (more within my YouTube channel). Here we have a dollar store type of flashing lights circuit, that has some interesting traits. The flash type can be set with…
