Archive of the former Yahoo!Groups mailing list: Homebrew PCBs

I have done some etching of small brass and copper/bronze parts in the
past, although not etching of PCB's, however this etchant/etching
discussion has me curious... has anyone tried placing a sonicair (type)
electronic toothbrush (extension, without bristles) into an etchant
bath for agitation? Just thinking it might make a simple, but
interesting experiment...
