I have made the older version of this power supply and i made the whole pcb the wrong direction by not mirroring it before printing. I do not want to make another pcb is there a way to make this? ??? Thanks :)

i already made up my mind making a cnc pcb router(computer numerical controlled printed circuit board router) when i make it ill post it up on the projects page

the problem is if someone in my family hear the word acid or any other as they call "science wierdo word" then they will freak out so i need some thing that's ingredients's names have no word acid in them.

Ferric cloride is what i used in the first place then i accidentally spilled it on our floor now there is a hole there and i needed an alternative.

oh i also added or use the most to make it make more sense

u can change the antenna windings by amount size and you can also change the thickness of the wire used. or add a variable capacitor across the antenna. hope that helps :-\

I am trying to etch a board but i don't have access to etchant and i tried the saltwater electrolysis etch proses. it does not work it just stained my pcb. anyone have suggestions for home made etchant? ???
