[sdiy] My PCB positives are see through!

Seems your right Tom.  I just exposed two boards and both came out
just peachy.  I used 2 20 watt 24" bulbs hung about 1' above the board
with an old window pane for a weight.  Now, I haven't etched them yet
so there could still be complications but it looks like 8 minutes
under the light and about 1 1/2 minutes in the developer does the
trick.  To be honest I'm beginning to get excited about this as it
really went without a problem.  Hopefully not just beginners luck!
