More detailed about Coil64

The Coil64 program is a 64-bit cross-platform open source application. The use, modification and distribution of the application and the source code is governed by the GPLv3 license. The application is available only for 64-bit desktop platforms Windows, Linux and Mac OS. coil64 - indactance coil calculator

Minimum system requirements:

  • RAM - 1024 MB or more;
  • Screen resolution - 1152x854 or higher;
  • Required disk space - 25 Mb;

In addition, the calculations and the source code of the Coil64 are synchronized with the Coil32 app for Android. You can download the desired Coil64 distribution from the download page.

The current version of the Coil64 allows you to calculate the following types of inductors:

  • Single layer air core solenoid with the round wire
  • Single layer air core solenoid with the rectangular wire (new!)
  • Multi-layer air core inductor
  • Multi-layer air core inductor with insulating pads
  • Coil on a ferrite toroids (only for low-current RF circuits)
  • The planar PCB coil with square turns
  • Tesla flat spiral coil
  • The app has the additional calculations:
    • inductor on a ferrite rod core;
    • finding unknown permeability of a ferrite toroid;

In the future, the other calculations currently available in Coil32 will be added to the Coil64 app. Coil64 corrected errors and optimized calculations, so the results with the calculations in the Coil32 may not match. Support and update of Coil32 application is discontinued.Coil64 ferrite rod

App Coil64 is multi-lingual. The application interface is available in the following languages:

Bulgarian Chinese Croatian
Dutch English Farsi
French German Greek
Hungarian Italian Macedonian
Polish Portuguese Romanian
Russian Serbian Spanish

You can configure the application by opening the "Options" menu item. In the first tab you can select the units of inductance, capacitance, frequency. Centimeters, millimeters, inches, and mils are available as units of size. You can select the calculation accuracy as the number of decimal places. You can choose to set the wire diameter by size or as an AWG number. In the second "Options" tab, you can select the application and output field fonts. In the third tab, you can check for program updates and set automatic updates.Coil64 options

In the main window of the app you can select the desired type of inductor, and then enter the necessary parameters for the calculation. In the first tab "Coil" is available to calculate the number of turns depending on the required inductance. In the second tab "Inductance" is available to calculate the inductance of the coil if you know the number of turns. In the third tab "LC circuit" is the calculation of the resonant frequency and other parameters of the LC circuit. Also additional calculations are available from the main menu of the Coil64. All calculation results are displayed in a common output field from where they can be copied or saved to an html, odf or pdf file, as well as printed.coil64 inductor calculator

Author of the Coil32

coil32I am radioamateur, especially I like creating short wave receivers, and also I'm programmer. In such creative process the left hemisphere of the brain is involved. Besides, I take a great interest of east philosophy and yoga, only without fanaticism. In this activity the right hemisphere of the brain is involved. Here and so from all this conglomerate of heterogeneous ideas and affairs this program was born. You get to know my name from program menu item "About".

If you have a need to contact me, you can use the feedback form on the site or send me E-mail from program Coil32 directly. Contact me via facebook.

I hope, Coil32 will be useful in your radioamateur creativity. 73!


More about the Coil32…

lcrFaced with the problem of calculating the inductors, and search for similar programs in the network, I found that most of the programs or old DOS-based command-line (which is archaic and inconvenient, excuse me the Linux terminal fans), or adapted in MS Excel. This induced me to create this program. Its name: Coil32, says that it works on 32-bit Windows, without the use of special libraries, such as Visual Basic interpreter, Java machine etc. I did it for myself, and if it will help anyone else, I'll be happy.

Assembler and not only...

Tao gave life to machine language. Machine language gave birth to the assembler. The assembler gave birth to the compiler. Now there are ten thousand languages. Each language has its purpose, sometimes modest. Each language expresses the Yin and Yang of software. Each language has its place in the Tao. But do not program on Visual Basic, if you can avoid it.

In this short article I want to support low-level programming fans. There is nothing about inductors, only about assembly language and programming. I remind you that Coil32 v4.1 written in this language. The source of this version is available for download , study and use. The required minimum programs to work with source – it: MASM32 v10 and above and WinAsm Studio.
