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.
Haha, the board won‘t win any prices for sure. But for a first try I‘m still very happy.
It's just the soldering. A drop of flux make wonders. The pwb is very decent, impressive even. You can be happy.
