pyFretCalc is a handy little fret spacing calculator for luthiers (Guitar makers). Simply enter the scale length you want and how many frets, then click on calculate
First you have to have the following software installed.
QT 3 http://www.trolltech.com
For Linux and other *nix's just untar pyFretCalc-0.0.2.tar.gz to any directory (like $HOME/bin) and run main.py. Future releases will use some sort of packaging.
Windows/OSx users: Follow the same instructions and let me know how it works.
NOTE: The tempered functions, and printing are not working... yet :-)
Oh another reason I switched to the PyQt toolkit... Liquid Rocks!
Better site on the way! :-)
