GALVA

I swapped my Windows PC for a Mac many year ago and never regretted the decision. There are some programs for Windows out there however, which are so unbelievably useful that just for them it makes sense to retain a PC or a virtual machine.

The French program GALVA by Jean-Paul F5BU is such a gem of a program that turns out to be a lovely toy for DIY electronics builders.

What does it do?

Galvas main purpose is to handle scales of instruments. It can create scales for potentiometers, linear or logarithmic, background scales for analog instruments, circular scales and many other things like the below attached SWR calculation disk, a very useful tool for radio aficionados.

It is controlled using a simple command language and comes with hundreds of sample files. The menu itself can be selected to use English, the command language however has a couple of French words in it which are still very easy to learn.

The program can be downloaded >>here<<
