It should be possible. The same method can be used to make Iron Oxide. Dissolve the Copper Sulphate and Sodium Hydroxide in a minimal amount of water each. Now pour one into the other. You should instantly get a precipitate. Stir it for a few minutes and leave for half an hour. You can then either slowly pour off the excess liquid and then add some more, clean water or leave it. Gently heat the mixture in boiling water and it should slowly change colour and change into Copper Oxide. Once done, leave it over night and then decant and wash you Copper Oxide.
No safety needs to be taken into account other than the obvious, don't breath in or eat anything, wash hands if anything gets on them etc.

btw are Copper Sulfate Pentahydrate (CuSO) and copper sulfate the same thing and if not what is the difference?
here is a link of the MSDS root killer k-77

would it be possible to make copper oxide using copper powder and hydrogen peroxide?
I do not think so. I am curious as to whether Dan was able to use his precipitated Copper II Oxide. When looking for info in my library, I only found references such as Weingart, that stated "only the fused (Copper Oxide) form is useful, the brownish-black, light precipitated oxide is useless."
KAABLAAAMMM!!!

and don't do it in an aluminium pot.

And store it in a airtight plastic pot, because it reacts with air to form Coppercarbonate ( Green powder )
