Big Joule Theif

[jeanna]

YEAY
Fantastic Mark

I love the way the lights respond to us.
It makes them seem more alive.

See if an aluminum pie plate or foil on the wall will do the same.

I think it is so interesting also that you can get a lot of these in series once the first one is lit.
My cfl did not get any dimmer when I added the tube to the string.
But I have not been able to add 2 cfl's in series... come to think of it, I don't have 2 modified 10w so maybe I could get 2 of them to turn on?

Very nice.
The fat tubes have a lot of gas, and the gas has to get "excited" for it to glow.
I was not able to get the 48 inch to light but the same diameter 24" worked just fine.

My house is cold. The funny thing about this is that the lights do not warm up after a while. Normally they warm up and also brighten.
So, wrap your hands around the ends and see if warming helps to brighten the warmer spot.

And, of course 3 volts instead of 1.5volts... but that is cheating!

======
All,
I am looking into a catalogue from the manufacturer of these toroids.

I think I have narrowed down my request to 3 toroids.
I would like to make the light go on with a smaller toroid, if possible, and I know you are all waiting for the supply of the 3.38" one to open up.

The southern CA distributor just suggested I go to the manufacturer, which I will do. Hopefully we can get somewhere with a local distributor who has a low minimum.
The toroids themselves are not too much, but the $30 minimum is a lot for one lamp.

I will return when there is more info for you.

Hey jeanna my 32 watt tube bulbs are pretty skinny not your normal commercial overhead size. There were from a light kit I was going to put in my walkin closet, bulbs are made by Phillips. I wish I had a 8 footer to try.

out of toroids...

Buy the way I can't find any other source for that core. I wish that I had bought a few more before they ran out.
Lidmotor

They probably ran out because everyone wanted to replicated the
Jeanna/Lidmotor light.

Way to stimulate the economy.

Really folks .. you can make coils out of all sorts of stuff.
The other day I was eye-ing an old truck wheel hub.
This sucker is a HUGE ... massive toroid of rusty steel.
You could wire up a coils for a Joule Thief or Rodin coil
using a wheel hub.
It might be a more difficult conversation piece ... since it weighs
about 50 lbs ...
But massive metal like this has a great effect in terms of
energy storage in your coil. I imagine all the little mini molecules
in it spinning around magnetically as your coil gets it going.
The metal acts as a sort of fly-wheel magnetically ... causing
the coil to have LARGE inductance.

With something even more massive like this, it might be
possible to light up some grow-lights for plants.
Imagine being able to provide light for your plants during
the winter using "earth batteries".
Such a strategy would provide the ability for food production
during winter years or in locations far from the equator.

Also, I would love to see experiments done powering
the big joule thieves using non-battery sources such as
teeny-tiny wind generators, little water wheels, steam engines
run from a candle, bicycle generators, gerbal/mouse-wheel
generators, hand-crank generators with capacitors,
thermopiles, ambient energy generators, antenna VLF-to-RF
power source, leaching power from dongles & transformers,
new battery chemisties, magnetic resonance.

In the mid 90s, gangs of techy punks used to go around
and TAG buildings to indicate sources of free wireless routers.
It seems to me that free wireless power is FAIR game
as well.
Let the Joule Thievery begin!!!!

Hi everybody,
I am getting some samples from the manufacturer of those toroids.
I am also getting a smaller diameter toroid, because the big one is so heavy.

I will let you know.

But I wanted to tell you guys about my experimental circuit.
It is even farther from slayer's big joule thief, but I hope it is ok since the topic has wandered.
I have made a new toroid winding design (in fact, I tried it out on the golden light = jeanna's lidmotor's jeanna's light) This one is very little gets 172 volts, and it lights a neon from a 1.2v battery. It's voltage is very stable, and does not rely on the most perfect tuning to get a good voltage. It is higher by almost 2 than anything I ever got with this .5 in toroid.

I brightly lit the 30 leds in my experimental circuit and added 4 more for the safety of the leds.
Would you like to see a pic?
Of course you would!

Pic is called Multiple secondaries full brightness
87mA for 34 leds in series.

Wanderings

@Jeanna
That is a bunch of light coming out of that little toroid. "More please". What do the secondaries look like? Maybe a little LED version of the JLJL in a smaller box??
I have also been "wandering" around and have been working on a replication of Jonnydavro's new circuit. He uses just one transistor, an HV trigger coil, and some aluminum pans to make an excited environment that self-oscillates producing HV all around it. The base of the transistor gets the feedback through the air.

Toroid (ICH) H5C2T31X8X1 1.23 O.D 0.718 I.D. 0.218 Thick
$1 each or $0.75 for 10+

is bigger better?
(ICH) FEROD-8 Ferrite rod. Material 43. 1/2" diameter x 8" long. for $0.35 each

I have no idea but could "Magnetic ferrite rod antenna" be used to pick up energy from Jonnydavro's new circuit producing HV?

[jeanna]

@vortex,
I think the permeability is the important thing to find out.
It may be too low.
But, it might be perfect??


@Lidmotor,
Yes, I have thought about jonnydavro's aluminum pie pan experiments too.
Many things are coming together, here.

@Jeanna

The 2 secondaries are wound differently from each other.
I had a hunch that if I did one of them in a way that got much higher voltage that the second one could gett a ride from that and could just be there, so the second is 'scramble-wound' but I kept it all on one side of the first secondary.

That first secondary is something I derived from using the MK1 style, which I have always liked a lot.
I was thinking of 3 phase one day and wondered if I used 3 directions of winds (which is the MK1) and made each segment a multiple or maybe exponent of the first, if I could get 3 phase.

The answer to that was no.

But, what I did get was about twice the voltage from the same number of turns.
I must say I have had really high volts before, but they required a very specific set of elements (to be at resonance) and would quickly degrade and the effect would be gone.
So, one of my criteria is that the bandwidth be wide enough to take a change without much loss. (and this is why I used the xtree in my experiments. It is really stable.)

So, to make this secondary that is in this one I have total 84T.
This number is divided by 7, so 12T go into each segment. Or, x=12
You will always wind (turn) around the toroid the same way but your progression will change.

Start a little to the left of center and wind 12T progressing to the left (actually 13 turns to give you 12 spaces.)
Proceed to the right carefully placing each turn into the 12 spaces. Continue 12 more turns to the right (again add one).
On this final lap you carefully wind 4 turns in each of the 12 spaces.

So, you end up in the center. You can keep the extra 2 or take them off, but I keep them because I usually lose count anyway.

On the big golden toroid (JLJL) I made x=30T but instead of 4T in the final lap I used 8T ... for a total of 330T for my secondary. Wow, I put the scope away at 1400volts!

I am still playing with this, but yesterday put the first one to the test, and it has worked beautifully.

I already made 6 videos on this circuit with multiple secondaries, so I won't be making more until I change the circuit, but if I can make one that works, I will post a video showing this winding method.
(MK1jeannaHybrid)

I found a source for boxes. They are from ritz camera and unfinished and cheap enough. They are a bit big for the one tiny 10w cfl, and I am thinking, a strip or ring of leds under a diffuser of some kind could work well.

I will make a pic when I have something using the box.

thank you,

@vortex,

That toroid has a permeability of 10,000µ (which must mean it is MATERIAL W)
and
that 0.5" x 8" rod is of MATERIAL 43 -- Permeability 850

Hi Vortex,

you could try it.
The W with a u of 11,000, is what xee2 thinks the big toroid is.
So, 850 might be a little low.
It takes many more turns to get any oscillation to happen when it is too low a permeability, so you use too much copper, put too much R into the equation, and you might run out of room.

I am getting some samples from the manufacturer of the big one, and will test the differences between a few permeabilities and sizes. Hopefully we will be able to know after that..

thank you,

Hi everybody,

I made a new lamp today and made a video of the stages in making it.

My Globe Lamp using 24 LEDs on the secondary

I hope you enjoy it!

Hi folks, Hi jeanna, nice work and nice lights you've built. I've tried the JT using my 13.8V supply and the transistor tends to get hot, although with bedinis oscillator the transistor stays cool, so I'm not sure if the JT is driving the transistor properly in all cases and with certain loads using the flyback it can heat the transistor. Though the JT circuit does work well with certain loads such as running the halo flouro bulb off a secondary wrapped around the bifilar winding. It seems that when using the flyback off the primary that if the load is say a battery with a lower voltage than the source the transistor will heat up. I'm sure you would find the same thing if you ever try higher voltages, though I wish I could get the JT to properly drive the transistor because it has a nice linear drive whereas bedinis oscillator is finicky. Anyway cool lights.
peace love light

reason for deleting my post's

Hello everyone.
The reason I deleted my post's were due to a virus that had gotten past my software.I didnt want to share a virus with anyone else.I ending up having to reformat my hard drive.I have a new anti-virus which I hope will take care of the problem. I will not use avast antivirus again. Thank's Tec

Nice one Jeanna. I like that you took an exsisting light fixture and converted it rather than completely "reinventing the wheel". I have an old LED camping lantern that I may do the same thing with. These Jolue Thieves can hide out undetected in all kinds of places.

Hello everyone

I have a new personal record of (8) 1.5 watt unmodified led bulbs lit with 1 AAA battery, for a total of 152 leds. I think I still have 3 more bulbs left so I will see If I can light all 11 here shortly.

[Mark]

Well that was a short record. Just lit up the last 3 bulbs. Now have a total of (11) unmodified led bulbs lit. That means a total of 209 leds lit from a single AAA battery! I'm beginning to wonder just what is the limit that can be lit off this big joule theif. Thanks Jeanna!
