But I have, on
serveral occasions, been designing anf prototyping
something and found at the last minute that I need, say, a 390 ohm
resistor. I don't have one in the junk box. In the old days, either in
London or Bristol, I'd hop on a bus and get 10 from Maplin. And be
designing again within the hour. Now I have to send an order to RS or
Farnell and make it large enough to meet the latter's minimum order
charge or so that the former's postage charge doesn't exceed the value of
the components. OK, there are always components I can use, but finding
the money every few days gets a bit much!
Resistors are SO cheap that pays for having a parts' tray with one
hundred of all values comercially avaiable and being replenished from time
to time. This is something you'll use forever. And doesn't get old.
