Joule Thief

[kamax]

I don't use a normal battery, just a earth cell in a pot(copper and a screw). You can see it on the beginning of the video, the initial power come from here, but it's very weak and never blink the led if i do nothing.

The cap is a 1000µF 6.3V connected in parallel to the cell. The resistor is a 1K ohm and the transistor a 2N2222A. For the toroide i just know it a ferrite and width ~13mm.

@ kamax

I am stumped. I took a coil and hooked it to a peak voltage detector and shook it. I was able to get over half a volt but it was drained quickly by the internal capacitor resistance. You must have a very good capacitor.

I'm not sure you have the same setup as mine, was your coil a part of a joule thief ? I suppose when i shake mine it just boost the energy coming from my earth cell who give continuously a little amount of power(~0.6V and less that 1mA).

But it is so amazing that the transistor even starts up at .6v.
If it could work so low, my earth battery which puts out .9v most non parched days would be lighting a led all the time.
I think it must be the cap.
Maybe the shaking gives the cap a boost as you suggest.

You are doing something really interesting.
Perhaps I should try touching my earth battery/joule thiefbase resistor in that same spot next time.
I will; and I will  let you know.
I don't have 1000uF cap,, just 65 or whatever you get in one of those cameras.

thank you,

Bienvenu ! You got your new toroid , looking good .

It may be  static issue , try moving the board on carpet , even holding the board and brushing your feet on the carpet may charge the cap.

This video is a example of how a transistor react under static stress real cool.

I also believe you could make improvement on your battery , maybe carbon and zinc or aluminum , or galvanized nail or screw witch is zinc , anyway the idea is to get metals with the bigger voltage potential range, at that point the electrolyte will insure meeting those potentials .

There is a book a book or two on the hendershot motor , scribd

Morpher44 started working on the device he as made many video

Also on youtube http://www.youtube.com/user/morpher44#play/all/uploads-all/1/O1EoFg7dy4A

There is a link between the magnetic battery , floyd sweet and hendershot , i believe the way the coil are facing each other .

I think i got more , i will keep searching .

@DonL

Nice work ! have you tried winding a secondary ?

@ all

Keep the good work everyone.

Also to keep you thinking watch the following there is 5 parts here is the first one , it gets better at the end , there is the first one.

Keep in mind if you could catch a high amperage current in a loop then pulse it to the need speed for the application, always using the same force and recycling it every time.
