Homebrew PCBs

I added the results of a 5/5 etch to my inket page:

I decided to be cautious this time.  As soon as the big blank spots
started vanishing, I stopped the etch, rinsed the board, and inspected
the smallest traces under a microscope.  They were etched!  They
looked unetched with the magnifier.  Took only 25 minutes for 1/2oz
copper.

Based on these results, I now know to reduce my inked edges by about a
mil to get the copper dimensions to match the design, as the copper
was about 2 mil thinner than planned.  I'm guessing the comb pattern
on the edges from the inkjet (which happen to be about a mil wide :)
cuts the UV down too much to get a full cure.  Might also be causing
the ragged edges at this scale.
