Sometimes you simply can not wait for "24 hour" or "1 day" turns in
the real world.
Myself I thought Dave's work was very well timed. Management saw
this: http://www.epiloglaser.com/ at CES and is thinking of spending
money (a rare event)
on one of them. There actually is a lot of industrial related stuff
at the consumer show.
What I wonder is if this Epilog machine can really do PCBs. I have my
doubts about etching the copper directly,
but I hope it can harden some pre-sensitize some board material, that
can then be conventionally etched.
I'll let you know if it happens...
