Pr. Badinov is a simple number base conversion tool handling decimal, binary and hexadecimal. Formerly a CLI hexadecimal ⇔ decimal converter for a school assignment, I turned it into a GUI software to try my hand at GUI programming.
(For what it’s worth: no pun intended in the application’s name, but feel free to think so.)
All you need is Python 3.x.
Then just go to the project directory and run python3 badinov.py.
