[EFM] Been quiet lately... too much DIY ?

Ah, autorouters. I don't mean to rain on anyone's parade, but there are certain,
er, risks when autorouting. We got a layout back from a contract house (picked
for speed), and all of the Vcc vias were tied to Vcc and ground. Five, cout them
FIVE engineers looked at the gerbers and didn't catch it until the boards were
fabbed and checked. Note that the PCB house didn't catch it either. 

There is a lesson in there somewhere, which I'll leave to you.

    Generally, the customers are more interested in having it now and cheap
rather than pretty and next week.  I have even in the past just done routing.  I
get the board, with all the parts placed and netlist loaded, start up the
router, wait five minutes, write out a bill for $500, and return it the next
day.  I wish I could make that kind of money all the time. :^)
