Here we are illuminating a 40 watt tube from a single AA battery. This is a modified version of Josepino’s disposable camera circuit. I have used this same circuit to light 2 of these 48″ tubes end to end. I have also illuminated 400 leds with this same circuit driven only by an old AA battery. More to come when I can get the time. More info on Overunitydotcom in the Joule Thief topic. Pirate Labs. …
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 at Overunitydotcom in the joule thief, and earth battery topics. Thank you. …
This is my replication of Lidmotor’s Jeanna Light using Jeanna’s large toroid Joule thief design and Lidmotor’s circuit. This circuit puts out between 1200-2000 volts! I do not have an exact measurement yet. (I am afraid of frying my measuring equipment!) This uses two 3-3/8″OD ferrite toroids, TIP 3055 transistor, 20 ohm rheostat, 15 turn variable 1k resistor, and 28 ga. magnet wire for the secondary and pick-up coils. I…
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 runs on 1 AA battery. This circuit uses a 2N3904 transistor, a 1K resistor, 1″ ferrite toroid, and 22 gauge bifilar wire windings. The components cost less than $3.00. This is easy to do and it is a fun project for everyone. This light will run on “deadR…
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 the camera. i am using my earth battery and running the output into two 2.3, 10 Farad supercaps in parallel with my modified Fuji joule thief circuit. The earth battery does not put out enough mA’s to run the Fuji circuit by itself. The supercaps allow it to power the…
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 Fuji AA battery circuit. for more info, please go to my topic “Joule Thief” on Overunitydotcom. …
Joule Thief Test circuit lighting 2 LEDs. One LED is 28500 MCD and the other is 265000 MCD. Each LED requires about 4.5 vdc each to light. Circuit is powered by single AA battery. More can be read about these experiments on Overunitydotcom in the Joule Thief topic. The transistor is an N3904 and the resistor is 1k. A Bifilar wound ferrite bead is used for the coil. It is wound with 22 ga. stranded wire. I have been able to light 400 leds from a …
This is a simple light fixture made using a modified Fuji circuit Joule Thief and a disposable plastic food container. It lights up an 18″ tube pretty well and this is very easy to read by. It throws light 360 degrees around the room and works well. I was planning on using another Jeanna light circuit I made but I must have a short somewhere so I stuck in the Fuji. I will use the new circuit on another light project when I get it fixed. Fo…
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 stated. It is good to get corrected sometimes. I won’t go through the circuit details here, you can check my earlier ones for this info. The only real difference is that I added a second 2.3 volt 10 Farad super capacitor to the circuit. I only did this because I …
This is a video of 3 LEDs (2-265000 MCD and 1-26500 MCD 10 mm Ultra brights)running from a single AA battery. Each LED requires between 4 and 4.5 vdc and over 100 mA’s each to light. For more info, see overunitydotcom in the Joule thief topic. This is just documentation of my beginning experiments, these little circuits have done more, much more and I will be posting more videos. …
