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.
That's a really nice project, I often thought of trying to do my own board to move project from breadboard to something permanent, and never got the motivation high enough to do it. So congratulations on your realization.
I must add, as a certified ipc-610 trainer that board gives me goose bumps, the Halloween kinds. (I'm just a professional critic, my projects are way, way worst)
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.
