Hi,
by "bad" I mean the name is highly ambiguous. Is "design" a noun or a verb round here ? JL and others seem convinced it is a verb: " to design ". But it is every bit correct to think it's a noun: " a design " .
It is very hard to discuss anyone's design without seeing a schematic and this NG is non binary. However it is easy to post links ( pdfs) to schematics found on the web, allowing discussion of them. But that does not work out too well either:
- Folk think they see flaws evident in a schem that does not exist in practice.
- Others may consider a schem fine when a built version is in fact hopelessly flawed.
- Folk like to make comments on a schem while barely understanding how it works or even what it does.
FYI:
I annoyed a few posters here a couple of years back by posting links to schems of well known audio products that were seriously flawed. I challenged folk to spot the flaw or flaws. Nobody here could.
Question for JL:
Where in the above did I mention " engineers " ??? Nowhere. And I was not thinking of them. I was not thinking of bench techs either.
JL wants me to debate his opinions with him. Not bloody doing. Like his faux invitations to post a schem of mine - it's a hostile trap. Since commercial products do not have the designer's name printed anywhere let alone their qualifications - one is left to guess. My guess is VERY few were the efforts of graduate EEs. They are mostly the work of " product designers " working alone or in a small team. Employed by a manufacturer or else free lance.
These guys specialise in particular products, constantly evolving new versions as required by manufacturers to keep them in business. Low cost design using only readily available components is crucial. A product designer must remain very disciplined to this need.
Most manufacturers have the idea that if a prototype works - it's fine to go ahead and mass produce them. Time's a wastin'.
So all non-obvious and many dumb mistakes get through regularly. A small sample wind up on my bench, having failed.
So Phil shakes his head and wonders:
" Who the hell designed this POS ? "
