RE: Tesla Coil Computer Programs

Ed, Ross -

I have used this spreadsheet and found it very useful as a TC calculator. It
is similar to the JHCTES Ver 3.1 program. However,  one thing I would like
to point out is that with the JHCTES program the user enters the primary
capacitor value and the computer finds the number of pri turns required to
keep the system in tune. This avoids the user having to vary the turns until
the proper capacitor value appears.

I agree.  Whenever I run a set of calculations on someone's coil, I just
save
it under their name and can go back to it in the future.  I find the
spreadsheet program very useful for finding out where to tune someone's
primary by playing some what if type calculations.  I enter the secondary
and
toroid information.  Then the primary info and check the required capacitor
value.  Then I go back to the primary calculations and slowly decrease or
increase the number of turns, watching the calculated capacitor value until
it gets close to the capacitor value that they are actually using.  Works
for
both of my coils.
