hi luther, did they write about connecting a battery / psu between the two 
electrodes
or simply using the different electrochemical voltages?

i guess this will only work as long as the copper is one area (when the 
edges are removed first it may be hart to connect the wire).

i would very appreciate to hear more from this, i will try it maybe next 
time...

but only because of interest, i think it is fast enough as it is...



but maybe hart to compare results... maybe 2 boards needed, one on the 
wire, the other conventional, in the same etchant
at the same time....
