heh, should be able to tell that by looking at it :)
Fortunately most hardware is pretty good with out of
tolerance values. However, I suspect many of the problems
that people run into are a result of less-tolerant hardware
(and shoddy construction and ill-fitting parts).

Cool, do you have a PCB layout for it?
