Big Joule Theif

[jeanna]

a new video

Hi everybody,

I made a new JT secondary powered light bulb modification.
I also modified the lamp so the whole lamp and bulb work together as a joule thief secondary light.

(aka jeanna's light, I think.)

19leds jeanna's light in a lamp

Enjoy,

jeanna

Thanks for your replies

Thank you for your replies... I am using this information for my joule thief maglight project.

Thanks

I haven't checked Mouser Electronics for these but there is no minimum order restriction so if you want to only buy a few parts you can. Of course, you'll probably want to make the shipping cost worthwhile by getting more in parts than shipping but there you are. I get most of my components from them.

Jenna and All,
Now that MATERIAL W seems worthy ..
I remind ya all of Toroid made of Material W (ICH) H5C2T31X8X1 1.23 O.D 0.718 I.D. 0.218 Thick
[/url]

Yes, vortex, the W seems to be the stuff.
CWSBytemark has a few of them in W and so does the place I mentioned above.(MTL??) and they both have minimums of $30.00 so even at 25 cents, the minimum will getcha.
I think these big ones will be around $5 or $6

Gadgetmall in NC has a website and he is buying an order of the big one (the exact one) for jeanna's lights for folks to buy from him.

Thanks Vortex.
Gadgetmall posts here too and sometimes calls himself fusionchip.
Yesterday he indicated that he already placed his order, but if you pm him you could let us know what he says.

thank you,

jeanna

$1 each or $0.75 for 10+ (using 2 coils might be effective )

Toroids: J type notsogood, W type terrific

Hi everybody,
I finished my test on the J type material I received as a sample from the toroid people.
I posted a small pic at ou and if you want to see the pic and some comments, here is the link.
If you are busy today don't bother.
I will not be using this type and the pic on overunity.com is for documentation only.

big flakey fight to light the 2 1/2" toroid J type material.

NOW
TA DA

I used the 2 1/2 inch toroid from the same folks but with the W core like the jeanna's light and it works fine.
I will post a pic, and here is the page on ou
the W type pix

Here is the info
2T,8T,100T
TIP31C
236r
835v465Hz ...very low!

It lights the 15w growlight tube and the 20w cfl easily and well.
Here are the pix.
I am going to wind this like the Golden one and see how it does with so many turns.
100T is very few, so I am pleased at this progress. I just want to push it hard and see.
here are the pix.

oops I forgot to measure amps draw, and when I remembered the AAA rechargeable was too low.
I don't have one charged up right now, and just popped in the Li AAA and OMG it showed 1200v (with the same 100 turns!)
The amps draw with that lithium is 160mA. I think I will recharge and try again with the NiMH.

Thanks Slayer007,
Thanks for doing that.

It makes a lot of sense, because raising the frequency will raise the sound above the hearing threshold.

For a long time I have held the thought that frequency of spikes operates in a pulsed circuit the same way amps do in a steady voltage circuit.
Increase of brightness with increase of frequency is a good piece of additional evidence for this.

(Of course I must also remember to add: when you increase the frequency in a joule thief circuit,you will also lower the volts. In a lot of these circuits that use spikes, we have excess voltage so it usually won't hurt the light.)

So, the trick is to raise the frequency to the highest level possible that allows the voltage to remain high enough to turn on and keep on the light.

thank you so much for doing and showing this... wow

@CosmicFarmer,
Hey thanks for the pretty wreath and ornament.
As an ornament it really looks great.

OK so, now add a battery and a bunch o' leds and put it on the top for the great star!

Very nice,

jeanna

In this video I just wanted to show the difference the magnets made on the JT transformer. Using the magnets on the transformer makes the light brighter.And makes it so you dont hear the transformer at all.

Here is the video.

Merry Christmas Energetic Forum



When I got done this looked too much like a Christmas wreath to not take a pic and share.

Put a whole green spool of radio shack wire on here. Might be around 400 winds or more, 3 layers scramble wind.

Happy Holidays

Hi uz
I made some normal led candle circuits about 5 years ago.
They had a 47r resistor and 1 yellow/orange led and 2 AAA 700mAH NiMH batteries.

Those batteries last 4 nights all day and night to 1 month all day and night.
The bright whites are the ones that run for a month or longer. I believe it is because they are so bright that when they are almost out, they are still bright.

My joule thief circuits are not normal because I remove the led from the transistor C-E and only use the secondary.

In my experience it is running the transistor that takes the battery power in this kind of joule thief.

The fresh battery 700mAH AAA again - only 1 of them, usually runs one to 20 lights for the same amount of time which is about 12 hours. [This means the energizer AA with 2500mAH will run for 36 hours.]
I personally believe it is because what is turning the lights on is the back spike from turning the switch on and off, and not mA from the battery like my plain circuits.

That is my experience.
Others use the joule thief in different ways and can speak from their experience.

Let the trumpets blare, and confetti rain from the sky..

How long does a brand new aa battery last on a typical joule thief circuit? with a couple leds?

Thanks

Hi everybody,
I received the toroids the other day and confirmed that the one I had and lidmotor etc used from allelectronics is indeed the

OW48613TC from MMI
The distributor in the southwest is MTL in umm I think Arizona or CA.
They have a $30 minimum and the price will be around $2 ea plus shipping.
So, Gadgetmall who has a website for this kind of thing made an order.
They will probably cost him $3 so my guess is that he will want 5-6 for them plus shipping to you.
I have not even talked with him about this but it seems right compared to allelectronics price of $3.50.
So, if you only want a couple instead of 15 Check out gadgetmall's website.
He will be letting us know when they arrive.

Now, I can get back to playing...

dual toroid

mark,
about four months ago when i bought 4 of these.. i tried all kinds of ways
that i will probably try again.. now that i know how to wire these things for best output...
thank you jeanna for your deep research and knowledge that you pour into
the toroids
i did notice a load on one side still affects the other side
its when there wired together the draw goes way down

If you can get your amp draw down low enough, and, depending upon what leds you use you can get one to run for months on a new AA battery. Gadgetmall has several that have been running for months now.

Something ?

Hi everyone.Here's something I am trying with two jule Thief's both with sec's.
both are 3 inch od dia.I cant find the one's used by Jeanna and lid motor I am trying to run the sec's back to each JT to see if this improve's the run time.will test these for the rest of the week.I tryed to wind a big sec last week what a mess a bird's nest looked way better al thumb's
Thank's Tec.
