This is my earth battery and modified Fuji joule thief circuit lighting 400 leds. Please see my other videos for explanations on the circuits and for more information on the earth battery. Join us…
This is Kubikop’s ‘Joule Thief’ charging light circuit that I replicated. Here I show what the signal from the transistor looks like on an oscilloscope. This pulse is what is doing the work of…
Here’s an interesting effect I discovered just now. Don’t think your JTs are inactive just because the light goes out! Something may still be happening. Oscillations may start and stop without lighting the LED,…
This Joule Thief work at a very very low input voltage from 0.125 to 0.35 volts and the output voltage is 2.7 volts, to the LED. An ordinary Joule Thief work down to 0.6…
This is another replication of the Lidmotor/Jeanna Joule Thief circuit. I am using two Lights Of America 4 watt (25 watt equivalent) LED bulbs being driven by a hand-wound 3.375″ diameter Lidmotor/Jeanna circuit. (TIP…
This is my earth battery powering a joule thief circuit and running 7 ultra bright, 10mm, 28500 MCD LEDs. I misspoke myself in the last video, these are 28500 MCD not 28000 like I…
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…
This is just a quick video of my new earth battery set-up. I am using the same 2 carbon rods but this time, on the minus side, I am using a large block of…
This is nothing more than a coil of plastic tubing filled with water. I added a 265000 MCD LED on each end of the tube. I am powering this with one of my Joule thief toroid circuits. Although it does light well on a single AA battery, I decided just to…
A Joule Thief night light made from an empty plastic water bottle filled with glass spheres and plain water. Powered by a single AA battery. (This is the same AA battery used in all of my video experiments to date) This is actually a lot brighter than …
