Ok , first the coils 3 and 4 are not connected to anything in the circuit except your load or a diode bridge.

It just a regular jt with 2 additional coil.If you can light the jt led you are all set.

This is the funniest thing nobody gets it , yet It so simple,Don't complicate stuff.

Don't worry i had to repeat many times already, Everyone want's to connect them to something , you are not the first or the last to make that
mistake .

Btw , your plan look like Lidmotor jt.

Edit: If it works the led , make a quick test, take any wire you got make one turn and connect a led to it.

hi Mk1

dont get angry, i have replicate it. To me it gives about 320Volt DC but only 0.23 mA DC. There should no LED connected. It is funny to see how it glows a neon bulb.

thanks

kinda reminds me if this lil unit ... 

ist

i see that they have thease 1 watt led flashlights on sale this week 15 bucks ...    im gonna go buy 1 ...  it is a single led ..

im a JT IT!!


then i need a small solar cell then a cap and no batteries

      The energy sure as heck is coming from somewhere.   Please look on any 1 atom as a wharehouse of ac voltage or a vibrating tuning fork and it's agoin at frequencies well above what we can hear or see.   Take this one atom and put it on the end of a rope and transmit the vibrations down the rope maintaining tension on the rope.  The rope will start to vibrate depending on how long the rope is and the tension.  The little vibrating atom down one end soon is able to store it's action in the field of the rope.  The best part is that little atom is gonna vibrate a long long time by all accounts.

I think maybe I understand why we are getting different results for large and small toroids. My large toroids were the same diameter as the small toroids but much longer. I suspect your toroids are the same length (height) but larger in diameter. If you look at the equation for inductance of a toroid at http://hyperphysics.phy-astr.gsu.edu/Hbase/magnetic/indtor.html you will see that increasing the area of the coil increases the inductance. This is what I was doing. But, you will also see that if the area of the coil is kept the same and the diameter of the toroid is increased then the inductance is reduced. I suspect this is what you were doing. So I think it is a matter of how we define "larger" toroid. Would you agree with this?

@xee2 that does sound quite intresting

guys just got back from the store what a deal ...

i got the 1w led light and there was 1 left on the shelf of this solar 3 pannel flashlight i was not going to buy it cuz it alomst would have broke me ...  but i said i need the darn thing and what the hell is money any way ... lol


so i got it too ... got to the till the thing was half price 

i love it !!! 

a pic

what am i gonna do with this stuff ...  btw the solar light also has a cell charger in it 

but b4 i get to this im gonna build a board that uses a watch style battery and charges a bunch of caps far beond what is posible of the tiny battery to further prove the point ...
