There is something to be said for designing on the fly.
It gives you a chance to test key parts of a design to validate
your ideas before you get too far along. It also lets you use
what you have.
If you have sufficient experience, you can get to the end
result more quickly, such as when I used to stop at
Active Electronics on my way to work,
and designed circuits for a 'we need it right now' project
to use what they had in stock. Now that Active
stocks bugger all, I am forced to do a full design just so I can
order all the parts I'll need the first time around.
If I find a nice part for a project, I -may- be able to get a
sample, but if I need 10, I'm S.O.L because everyone is only
interested in 5k+ piece orders. MOQ (minimum order quantities)
are killing basic research and development by hobbiests. Thank
goodness for Digikey, even if they are pricey. But if the big
mail order houses don't carry a part, you're out of luck unless
you have deep pockets and can afford to waste 90% of a MOQ order.
