Homebrew PCBs

Well - I had to try it at least . . .
The Oxygen tabs I tried did not generate enough oxygen to make many bubbles in the tank.  Perhaps the tabs were old, but I doubt if new ones would have been much better.

I'm guessing that it should be as fast a regenerator as Hydrogen Peroxide . . . and not any more expensive when compared to 30 or 40 volume Hydrogen Peroxide - plus the etchant will not be diluted.
