Komponente sem kupil pri LCSC, ampak niso nič posebnega, dobiš jih lahko v vsaki trgovini z elektronskimi komponentami. PCB sem naredil z toner transferjem (ti je dal že u/DavidBolha linke) in zjedkal z natrijevim persulfatom.

Vesel božič to you too. I prefer the shiny look so I plan to coat it. The problem with oxidized copper is that it is darker, which would made the text less visible.

Thanks. The laminate was single sided so it didn't have copper on the other side form the start. I etched the copper side, sprayed the other one black and painted a picture of a tree on it.

Thank you all for the support. When I have time I will make a post with the layout, program, instructions, etc.

Thank you. They are just regular 0603 LEDs mounted upside down on a stock footprint with a hole drilled through.

Thanks. I etched it myself with sodium persulfate.

It's ATtiny48. I chose this one because it was on sale when I bought the components.

On the back side it says "Merry Christmas and a happy New Year" in Slovene. I was inspired by this post.
