Re: ScanTesla - Prime Time Version

Original poster: Rich Simpson <richcreations@xxxxxxxxx>

Hi Terry,

I was able to make a few small changes to your program to allow me to
port it to Mac OS X, it builds clean on the mac (using gcc4.0) and
seems to work.

If you are interested I can send you my changes (one really small
change actually, conio.h does not exist on my machine, nor does it
seem to be needed, so I just commented it out in your file)

I often wish that more software such as this were made for mac as
well as windows (linux too), and I am willing to test/port code to
the mac for the better of tesla coilers everywhere, so if you have
more stuff that could be ported to unix (mac/bsd/linux) let me know,
and I will try to make it happen.

Keep up the good work,
-Rich Simpson

Hi All,

I think I have a version of ScanTesla ready for the masses ;-))

http://drsstc.com/~terrell/modeling/ScanTesla500.zip

The parameters are input by the simple text file "input.txt".
It can do a DRSSTC or conventional coil.
It can find the maximum streamer energy or the maximum top voltage.
It reads out as it goes and stores everything to the file
"output.txt" too.
It seems to all work fine ;-))

The C program is included and perhaps sort of understandable...
It was made and compiles under LCC (free windows C compiler), but
now you should not have to change the program itself to run it.
You only need a C compiler if you want to go changing the program
itself.

http://www.cs.virginia.edu/~lcc-win32/

The input.txt file is now set to scan Lprimary from 10 to 100uH in
steps of 0.5uH and scan Lsecondary from 20 to 200mH.
It is set for a conventional coil with 20000 volts on the primary cap.
It is searching for the combination that gives the maximum top
toroid voltage.

In general, the search parameters are start value, stop value, and
increment value.  If the start and stop parameters are the same, it
is a fixed value.

You can change the input.txt file to do anything.  There is no
error checking so garbage in, garbage out ;-))

Cheers,
