This was my first try developing my own pcb with the toner transfer method. I did this project many years back but it works perfectly to this day.

It filters an audio signal and drives led strips so they pulsate to the beat of a song.

I'm using a 10W laser at about 25% of its power. It's a 450nm laser that is sold as 80W electrical power on AliExpress but Chinese webshops often exaggerate their specs.
