Has anyone made a variable power supply for use in home electroplating ?
It depends on how much current you need. Plating is best done with a current-regulated supply (not voltage-regulated). It is relatively simple to build a current regulator if you have any experience with electronics. Email me for more info.
Another good solution is to just buy a switchmode bench supply from EBay. Some are well under $100, and most of them are capable of regulating both voltage and current.
I'm not an electroplating expert by any stretch but I do know electronics enough to agree with Don that if you arn't an expert the best route is to find, buy, adapt. It is a rare day when reinventing the wheel is the best route with electronics.
Figure out just exactly what your needs are and then let google and other search engines be your friend. Very good chance Ebay will have just what you are looking for.
Toni I don't know what finish you are looking for but I've used products from these folks in the past with great results

For my power supply though I had re-purposed a 650 Amp DC power supply from a large mig welder. But we were doing 1000s of small parts contained in baskets every week
Never try to tell me it can't be done
