Hi,
some testing done with sulfuric acid and normal solder wire as anode
I uploaded a few photo's shown the huge tank and the result :))
http://www.xs4all.nl/~atmel/fotos/album1.htmlthe 1st result was get cristals on the surface after bagging the
tin in a coffee filter makes much better result
also the voltage as low as 2 volts helps
i like to use the tin as a resist for etching (in future)
it solder real easy components on so gonna use it as anti oxidize for
copper (instead of a flux)
just have to hot weld another pvc tank for it
any sugests always welcome
the little red tank is 5 x 5 cm :) filled with dim water and only a
few drips of acid
