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.

      It’s just the soldering. A drop of flux make wonders. The pwb is very decent, impressive even. You can be happy.
