Tesla coils back to back.

[antimony]

Hi, i am reading Kellys book, chapter 3, page 157 where he describes someone that have used two TC´s to power loads, and doing the regular stuff. It sounds interesting as i am starting to make my first Tesla coil ever.

Anybody know more about this, or have perhaps tried it yourselves?

I know of this one

Kelly's book is a nice read, but don't expect all the promesis to be true.


I enjoyed the optimized joule thief plans. Also the links to 555 schematics.


There was a claim, widely disputed, that you can pickup a tesla coils field without back emf, so basicly you could put a ring of tesla coils around the first one and use that induced current at no cost.


But I guess that would be without the connecting wire at the top.

I am trying to get into TC basics now, and i have wound my first small TC secondary today, and i will try to get into tuning a bit now.

When i first started reading Kellys book i was sceptical, and then i became sold, then sceptical again back and forth. It seems like it is a good source of information thou.

I think Tesla used the magnetic reactions of the bi-filar coil to create a rebounding field.
But it has to be timed or it won't work.
I've had coils bouncing all over the place, just by hooking them to shorting brushes on the commutator.
The trick is the timing.
You have to figure out when to use it.
Sorry just on a bit of a rant tonight.
