Homebrew PCBs

Today I remembered to heat my etchant.  I just ran hot tap water into
a large container, and floated the FeCl container in it.

Although it had cooled some (the water bath) by the time I got around
to etching (had problems with blue TT paper, ended up using white),
the etchant was still warm enough that the copper almost seemed to
just wipe off with the sponge!  The board was etched in no time.

So if any of you haven't tried heating your etchant yet, try it!
