Installation

You can install Coulomb from Flathub.

Alternatively, you can download the jar file directly from releases

Features

• Draw arbitrary circuits
• Plot voltage and current of devices against time
• Save/Load circuits
• Dark Mode support
• Beautiful UI

Available Devices

• Resistor
• Battery
• Current Source
• AC Voltage Source
• Inductor
• Capacitor
• Diode
• Zener Diode

Problems

1. Circuits containing non-linear devices will most probably not be solvable, because the current backend is not good at dealing with non-linear systems, that's going to change though.
2. Due to the way inductors and capacitors are modeled you can't put two inductors in series, or two capacitors in parallel, that's also going to be fixed.

Building From Source

1. Make sure Gtk4, libadwaita and Gradle are installed on your machine.
2. Clone this repo:

git clone https://github.com/hamza-Algohary/Coulomb

3. Navigate to project's folder

cd Coulomb

4. Build and run

./gradlew run

[!NOTE] You can also build the flatpak package and run it:

make
make run

Credits

• Coulomb's backend uses Efficient Java Matrix Library for solving linear systems.
• Coulomb's logo is designed by Alhussien Algohary.
• Coulomb's behaviour is inspired by Paul Falstad's Circuit Simulator
