PCB etched with toner transfer method
(lemmy.world)
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.
Nice job! I never got toner transfer to work properly, I used UV instead
Yes UV is so much nicer, I also use this method now when I‘m not ordering online.
