But not, AFAIK, in the UK...
Aww heck Will. Why spend a buck when you can spend so
much more=2C and cou=
ntless hours making some obsolete technology perform?
I can think of one very good reason. It's called 'Education'. If you jsut
use a black-box solution, you don;'t understnad how it works, you don't
know how to debug it if it dorsn't work. If you design the thing, then
you (hopefuilly) understand what you were trying to do, so when it
doesn't work, you know what to test, you can then redesign it to work
properly.
I get verry worried by jsut throwing black boxes at a problem. Somebody
had to design said black box in the first place. And if you don't
understnad how it works, who is going to design the next generation of
modules?
Put it this way : A so-called electronic design (in any area of
electronics) who can't work with discrete tranisitors is going to get no
respsect from me.
