Coil32 is inductance coil calculator, that allows to calculate the single-layer and multi-layer air core inductors, the ferrite toroid inductors or chokes, flat square coils on PCB etc.
The app allows to calculate needed number of turns for desired value of inductance of homebrew inductor or to calculate the inductance value of a fabricated inductor. I hope this app could be useful for HAMs, Audiophiles and other radio enthusiasts who needs to make DIY inductors. I need for help from native speakers to translate this app in Indonesian etc. If you can give me the help, please email me.
Nice but... When calculating a single layer coil, winding length is displayed in the wrong units. I set my inputs to be in inches but the calculated result for winding length says 30.62 inches. Should be either 30.62mm or 1.20 inches.
The best It's not often I take time to rate apps and it's even less often that I will rate an app I haven't even used yet. However I just tried their Cantenna Calculate app and it is so fantastic that the rating I have yet to give it was so great that it messed with space time and retroactively inspired me to post this. Getting serious though, these apps are perfect, very simple specific application. If you need something complex we have Matlab.
