True. But sometimes when I have a hunch they could change their mind I
quietly add stuff, just in case. Last year on a dosimetry design:

Not going to happen. We already made 10,000 LCDs with MPH/KPH on a
previous version. This is just an updated design.


"Well, ahem, I guess we should have written the spec so the design could
also support double dosages but I guess it's water under the bridge
now." ... "Not too late, just move the resistor at R41 to the empty
location at R44." ... "Whew!"

We had some customized LCDs made once. It was a *very* minor variation
on a suppliers standard product. They were about half the price of
their standard ones! Apparently they price custom parts with a
different system. :)
LCD pricing is often weird. Standard products are expensive unless you
can find a cheap source other than the mainstream distributors. It's
similar with HD44780-equipped alphanumeric versions where distributor
prices are often outrageous. No idea why.

LCD productions are very labor intensive and difficult to change.
It's unlikely to find any distributor who would be willing to stock
"standard products" as well. Making custom products and standard
products are the same. They have to setup the entire production line
to make them. They can make a few hundreds, but probably cost the
same as thousands.

I realize that. But often the modules sold are identical to ones used in
fax machines or printers, yet they want top Dollar. And then the sale
doesn't happen because everyone goes custom or opts for another kind of
user interface.

We deal directly with the factory. The "standard parts" are for
references only, since they don't really stock them. Once they have
the tooling done, they can turn out 10,000 in a few hours.
