Electroforming from scraps?
I was reading the Electroforming 'ible https://www.instructables.com/id/Electroforming-an-Iris-Seed-Pod/ and I have a couple of questions:
1) It says you need an 18 amp digital rectifier. However in step 13 it says "Check the amp and voltage setting, they should both be at or below 1". Why do you need an 18 amp rectifier if you only need less than 1 volt and 1 amp?
2) Is it possible to build some sort of a suitable rectifier from scrapped microwaves? I know people wind a 10 gauge secondary into the MW transformer to make welders, so can it be done for electroplating too?
