I purchased this now, will be able to test after returned to India.
Nice Tobias. Single sided boards are a little easier to etch for me but someday, I must learn to do double sided boards.
Someday when you get a chance, that AD815 dip board would be nice too. I have a bunch of them laying around waiting to heard. I did do a single sided board, but the layout with that chip is critical. A little too fussy for me.
