@Bill
Good to see you again Bill
Bad things those tornadoes

@All:
Great work folks!!!!!
We had 3 more tornadoes touch down here within 10 miles of me.  These storms have been rough.

Bill

I hope you have one of those underground bolt holes at your place to take refuge in, don't be brave and sit it out on the surface if one of those things heads in your direction.

I feel for those who may have been touched by them, 3 tornadoes in 10 miles, is a bit scary

Take care.

Altrez,

I got mine at allelectronics.
It is a tor-60,  $3.50 each
http://www.allelectronics.com/make-a-store/item/TOR-60/3.38-DIAMETER-FERRITE-TOROID/1.html
this is 3 .38 inches in diameter.

That will be great for you to get one of these!

@MK1
On the top of the last page is one of the best descriptions I have ever seen on the winding of the Bifilar coil, terrific art work, its a good find.


Same with the MOBIUS coil setup, I wonder if it is possible to make a Mobius secondary?

Nice work mark

@electricme

Mobilus , both ends of the coil show the same polarity , easy way is to change the winding direction midway in the coil.

Edit , yes nice drawing (tesla) , that way both sides of the coil have the same power both side are as strong.

So Mark,
How are you testing the mobius?

If you made it on a nail which is easy to try, then what did you do, please?

Also,
Please explain how this is different from the MK1 design pickup?
OH NO wait... I see there are no crosses in the tesla. but there are crosses in the mobius, I thought.

Mobilus , both ends of the coil show the same polarity , easy way is to change the winding direction midway in the coil.

That is the MK1

thank you,
