wavelength calculator.
I am still kind of looking for a toroid inductor calculator but I found this in my bookmarks.

To avoid confusion , i have to say that what most people refer to when speeking of mk pickup coil , it is not the way a last presented .


Now 3 volt over 20 turns fine. 6v=40t ,9v=60t ,12v=80t ,15v = 100t,18v=120  20v = 140t

So i see a 20 volt gap with 140 turns ...

guys i never said i had it 100% figured out

thats the fun in it 

mk1 your gonna love this pic ...    i took it just for you

this first pic is my KICK STARTOR .. 

next pic is the next level unit ...  still lame ass switches ... but  1 shift at a time .... 

this is a kit i bought last year ...  never bothered to assemble it yet...  no rush ...

it is for better tuneing .. BY SOUND WAVES   now i do have far in advance of the TESLA POWER UNITS SHOWEN .. 

but they operate diffrently ...  more a UFO thing 

ist!

this unit is an execlant item for parties and dances...

Thanks,
Now xee2,
Have you calculated either of your coils?
If you have, what is the inductance you are calculating from them?

BTW folks,
I just got back from my annual trip to home depot. I picked up a 4 watt fluro tube. I will give it a try tomorrow since I don't need to be up til 4AM just to watch it go out! 

And they have a smaller globe (like the one I pictured last week) for 7 bucks as a ceiling light with a pull switch. Hopefully I can rig up the light socket with the jt battery so that a nice bunch of JT secondary leds will turn on by the switch. (the one without the switch was $5 or 6.)
The globe I got last week is so bright I cannot use it as a night light. It is too bright with 3 leds.
So, I will put 12 or 18 in it in series/parallel.
Then it will be enough to light the room.
One more directional led would be enough to read.
Good for those T-storms and blizzards.

@ All:

Yucca posted this link over on the Kapandze topic and I thought it might be useful for some folks over here.

High voltage resistors are expensive and he said this link shows you how to make an adjustable one for free:
