I need to control the speed of my wall fan in my workshop - but the dimmer I'm using is so noisy!
JLCPCB Only $2 for PCB Prototype any colour and easy integration into EasyEDA

The standard, leading-edge bulb dimmer buzzes and so does the fan. It's driving me mad! So how do I control the speed in a way that is silent?

After many weeks of gathering the courage to spend the not inconsiderable money I finally plumped for a UK-sourced Variac, or auto-transformer.

Why would this work any better? Watch the video and find out!
