[TowerTalk] DIY Air Wound Coils

[David Gilbert]

Are you asking if my OpenSCAD code pulls variable information from 
Brian's excellent COIL program?  If so, the answer is that it doesn't.  
You can get what you want from Brian's program and then load those 
numbers into the OpenSCAD files.  Somebody could probably write a script 
to directly pass the variables, but I don't see the point.  For one 
thing Brian's program assumes a coil with uniform diameter and the 
version of my files you are referring to results in a slightly tapered coil.

If you're simply asking how to use Brian's program,  it's just an 
executable file.
