From the project

Small learning project for a DIY fume extractor using a 9v battery and a 5v replaceable fan

KiCad project for a small, battery-powered fume extractor: a 9V battery feeds an L7805 linear regulator to drive a 5V fan through a BC337 transistor, with a potentiometer for speed control, a trimmer for calibration, a power switch and an LED indicator.

This is my first electronics project, so it's a work in progress. Expect multiple revisions as the design gets refined.
