Can I perform electroplating with sodium carbonate and copper?

I want to avoid anything poisonous during electroplating. I can't avoid copper oxide though.

I have dissolved $\ce{Na2CO3}$ in water and I'm trying to electroplate aluminium with copper:

As you can see I'm doing it with no actual chemical equipment. Actually I'm trying to discover ways that can be done at home.

In the water, I can see copper hydroxide ($\ce{Cu(OH)2}$) and copper carbonate ($\ce{CuCO3}$), both formed from the copper anode. But the aluminium heatsink does not seem to have any copper on it. Will it take time or am I just wasting copper here?

If this is not gonna work, what is gonna work? Could I use vinegar?

• What does it mean some copper oxide? What kind of substance did you use for adding copper in the solution? $CuSO_4$? – Jaroslav Kotowski Jun 26 '14 at 10:54
• The copper oxide is generated by the oxidation of anode (which is a copper PCB). If I had $\ce{CuSO4}$ I'd use it as an electrolyte. And I was wondering if vinegar could help instead (because I don't have $\ce{H2SO4}$). – Tomáš Zato - Reinstate Monica Jun 26 '14 at 13:40
• It is possible to buy copper sulfate in a shop (it was used for pool cleaning). Without copper in the solution the deposition will not occur (oxidation of the anode is in this case insufficient). I have seen some recipes where vinegar was used, but the deposition will be complicated. For direct aluminium copper plating is generally used cyanide baths (I am strongly against using them). – Jaroslav Kotowski Jun 27 '14 at 8:41
• I was thinking that if dissolve the copper hydroxide and copper carbonate in vinegar I could electroplate with them. But I'm not sure if it's that easy. I want to avoid any poisons. From what I have discovered, both copper compounds in the solution are not poisonous. Copper sulfate is poisonous (especially dangerous to human eye) and I guess cyanide isn't safe either. – Tomáš Zato - Reinstate Monica Jun 27 '14 at 9:48
