Hi Scott, Gary, All,

I had a little "java" fun today with Pete's Spreadsheet.
http://www.classictesla.com/java/2layer/duallayer.html

I've been wanting to throw together a work of miscellaneous calcs we 
all need from time to time. The Dual Layer Primary Inductance 
Calculation seemed a nice place to start.

So, there is now a javascript version at classictesla which everyone 
can use to calc the inductance of a dual primary. I'll keep a link to 
it on my main page.

I made some minor corrections for wire length and coil width, but 
everything else is all Pete's derivations of Wheeler formulae.

I also made it work for both inches or centimeters.

Take care,
Bart
