JT nuchillis we do!
But where to get a little alternative inergii 1.2 -1.5 volts?
Wood + ground? Air + ground?
We used steel nails for wood, copper rod 40 cm for the land, 25m copper wire for the air
Found in the Internet scheme for the application of air + scheme (CIRCUIT) + ground, but the result is zero.   
Tried tree + scheme (CIRCUIT) + ground zero result. 
Wood + ground 0.2 volts! 
Air + ground 0!   

What do I do that correct?

a few days ago i did a basic plasma refresher cource ...  passed with my eyes closed ... : )

3vdc supply ...  no transistor ....    i can even wobble it if i want to ...  but it burns things up ... 


so with the super high speed plasma ... and some tuned plates ..  ground and  air becomes intresting ....

@ist

Ist knows everything , because aliens come and visit him Yep he told me .

Ist offers money for work , actually i seals every idea on the net and them claim them as is, because frankly he is a moron , i spoke to the guy many times, i know.


Some think you are a troll , i use to think everybody had the right to speak .

Ist is not a troll , he is just a kid that could not finish high school , he thinks he is brilliant , and he is quite a sculpture artist , because that is all he makes ...

he doesn't have enough focus the right clearly , because it to hard , and not his style .

And that way he can fool people for a while .

I tried to tell you , to wise up , you brush it off . so be it .

Ist has a big ego , things his ego prevents him to know , first he is a child ( so don't bother if he tell you to grow up.

ist second even if he could explain it to you , you would not understand(he would not undurstand)

I am sorry dude , but really find a job , stop feeding of of other s work.

It doesn't work anymore .

But my favorite one , i can't post it they will break my pc screen .

I am a patient man , but that is where i draw the line.

Good i wish i had the power to put you on read only , until you learn how to interact with adults.

Here is my coil!  It has 2 primaries with 2 sides going to the positive rail and then 1 going to the base and 1 going to the collector of the 2N3904 and the emitter going to the negative rail.  The secondary is 5-6 winds of lamp cord and shows 1.1-1.5vAC...It wont light anything?  Also the base and collector turn amounts are different from each other...not sure how many!  Any advice?

@stprue

Nice looking coil.

Ok , first i only did this with cardboard tubes so far , in case its a material issue.

Ok , so you connected it like a regular jt , then reversed one wire if it did not work ?

Dose a led work at the transistor ?

Edit , lamp cord lol , you need more turns on the secondary and try i bit smaller wire not covered. to get the wire closer to the primary.

The field around the toroid is not big , that is not how it powers the secondary.

try different size secondary , put more then one at a time .

This a jt , 1.5 , not 9v ... soon

Also try a pot for base resistor (tune it to best performance), also make sure the transistor is good , one of my 2n3904 did not work good either .
