Joule Thief

[Mk1]

@all

It was a demonstration of my new tool , to analyze the performance of my new coil, and there are no other way i could think of .

Now my new coil doesn't seem to show really high voltage , but it has more power then any coils i have made before.

The output from the secondary are almost independent from the jt circuit , it helps when you have many secondary , even the pickup coil is loaded the jt runs unaffected.

It runs motor 12 dc no cap , filament bulb , not the regular jt .

I did see your experiment with the cone, 2 turn secondary plus asymmetric pancake coil .

Now for the Cardboard tube , you need 2 coils going around the core like a regular toroid, but the coil needs to be at 45 degree on both face of the core , those are the base and collector coil the one on the outer rim is the pickup coil.

This is a basic version , you are supposed to leave room between the wires ,

Also when i say many time around (revolution ) , You understand , A bit like the Rodin coil .

The secondary works with bigger wire , bigger the better , More turns on the base and collector coil means more out of the pickup coil.

my new coil

That is an amazing coil. Will this version light a filament bulb using the pickup coil?

Yes , i am already on a new one , i will try to make it better , they all light filament bulb , to different degree , but there is so much more to it...

I will try to make one from a smaller tube , commonly found around the house and take all the pictures needed to make some follow along instructions.For those that really need it , but honestly it is so new , better design will come along , lets let it evolve like the jt usually dose .


But this is like step one , and it feels like going backward , but there is more then just volts .


Thank for your interest.

That is good so far Mark,
Now, how are these 1 and 2 to be connected?
Are they eventually connected to each other in series?
Are they connected end of 1 to beginning of the other?

The secondary is easy,
It is the primary that nobody has managed to get through my head!

@All,

I just posted something which I believe will help many who live in countries where they cannot buy the toroids we have.
I just took the little orange toroid from a small cfl and made a very powerful joule thief whose secondary is 60v at 62Khz.
This will light 8 leds blazing bright (as I showed) and with 10 strings of leds connected in parallel the amount of light will fill a room with no more amps draw from the battery than one led.

I wrote the recipe.
I am very pleased to have been able to do this.
I hope it can help many people light their homes.

@ Mk1

and take all the pictures needed

Great. I think a photo of just the base coil on the tube would help people understand better how it is made.
