Homebrew PCBs

Though I confess to only trying the sponge-etching process once, it was very
labor intensive and I had miserable results with it.

It took about 15-20 minutes of manually scrubbing the board, and still made
a considerable mess.

Also, though it worked well with my toner transfer pattern, it scrubbed all
my resist-ink corrections off the board, even the really dark traces.

I expect my method can be improved upon, but I found that using even a
simple etching tank was much quicker, even including all of the setup and
putting away.
