Joule Thief

Hi guruji,

first go here:

There is an amazing amout of information on earth batteries.
That thread was originally called earth battery etc. but it migrated to be a stubblefield thread, but the whole first 6 months or more were strictly earth battery.
That is where Bill originally posted his pix with the eb lighting the led.

enjoy.
There is a lot of activity going on there now. It mostly has to do with stubblefield, but plain earth batteries belong there too.

see you there,

Hi everybody,Here is what I have playing with for the last couple of days.

I hope it is just the media stick, but my camera quality is dropping fast. I do apologize, but it is a short video and worth a couple of minutes.


I made a cone with 2 wires.
It is a single layer but made with 2 wires.
I didn't get much response and I was sure that I would, so I kept on trying things.

In the end, or is it the beginning? I used a simple joule thief toroid wound as a primary.
This is 5T,8T center-tapped, of course, and I put that into the joule thief circuit to create some pulses and then stuck it like a cap onto the small part of the cone.

Next, I wrapped the top wire pair around the toroid 2 times. (2 times but 2 wires makes 4 turns total around the toroid).

Then, I took the red one from the top and connected it to the bottom end of the green one, and looked through the scope at what those red and green wires were doing.

At one resolution I see the jagged triangle wave that we see on the EER a lot.
At another resolution, there is a series of balls with spikes coming out of them but my favorite is the one that looks like a spiral. If you watch it in motion.

Please have a look. I will deal with the camera next week.

thank you,

jeanna

Hi, Can someone point me in the right direction...

If I have a simple Earth Battery at say .9v 2 mA and hook it to a super cap say 2.5v 55 farad and let it charge cap all night, will the cap have enough mA's to power joule thief LED for few hours
How much current will collect in super cap from EB ??

Make sure you use a diode to keep the energy from draining out of the supercap!

Actually it would be terrific if you would do this until you got something and let us all know the answer to that. We have been trying to figure that answer too.

Bill has lit a bunch of things with his, and some others have said they did too, but the closest I ever got was to make a set-up sort of like yours to collect a charge and charge a battery. I charged 2 batteries but only to 1.17v. Pretty low, but they were able to light a led... but not directly (yet)
