The power supply I use is actually HY1803D (sorry I misread).

I noticed that this technique works for plating tin and copper (presumably nickel as well). I suggest you stick to copper though - organo-tin compounds are extremely toxic (and could conceivably form as a side product) and nickel salts are carcinogenic.
This form of plating does not appear to work well for plating zinc, aluminum, iron, magnesium, or sodium (of course). This is probably because these metals are too high on the activity series and dissolve right back into solution once they plate (if they do at all). I also noticed that if the solution is not heated, a black film will develop on the object being plated. This is copper oxide. Solubility of oxygen is reduced and conductivity is increased if the solution is heated (also increases acid dissociation increases dissolution rate of copper oxide).
