Sure. But what the client asks for, what the client wants, and what
the client needs are three different things.
---
And you, of course, are the one who will determine what the client
gets?
Reminds me of the joke where this guy goes into a brothel and asks
the madam if she runs a union shop. The madam says no, and the guy
asks how she splits up the take. She replies, "Well, out of every
$100 we take in the girl gets $40, the house gets $40, and I get
$20.
Outraged, the guy leaves and goes to another brothel which he finds
_is_ a union shop and that the girl gets $60 and the house gets $40,
out of which the madam takes her cut. "That's more like it," he
says, "I'd like Lily, over there."
"I'm sure you would," replies the madam, "but you'll take Emma; she
has seniority."

You get satisfied customers by giving them what they need at minimum
expense. If they really need a BCD display, that's what you give them,
but if they can settle for two parallel octal rotary switches
displaying all the octal numbers from 00 to 37 or one hex rotary
switch plus a toggle switch the circuit can be much simpler and
appreciably cheaper
---
What a horse's ass you are.
One gets satisfied customers by giving them what they want, and
second guessing them by telling them that what they really need and
what you'll provide them with is the Stilton you've selected for
them instead of the Roquefort they really want isn't going to get
you many happy campers.
Or, BTW, many employment offers.
---
I prefer to give them what they want, rather than what they ask for.
---
No, you prefer to give them what you think they should have.
---
Getting them to understand what they actually want can take a while
and requires some diplomacy - not one of my strong points and not a
skill user groups offer the space to exercise.
---
I think the problem isn't one of their being able to determine what
they want, it more like your _not_ being able to determine what they
want and trying to force your decision of what they need down their
throats.
---
One of the marks of a good designer is that capacity to step back and
see what the client wants done - this does require some understanding
of what the client might be trying to achieve, and can frequently
avoid a great deal of unnecessary elaboration.
---
Yes, and you certainly proved that you had no clue that the OP
_wanted_ to be able to switch 31 channels and get a decimal
representation of the hot channel decimally when you unnecessarily
elaborated on that totally useless hexadecimal implementation.
---
Silk-screened front panels cost money - for prototype work we just
used Letraset transfers onto brushed aluminium to create the legends
and protected them with a layer or two of polyurethane varnish.
Cheaper and a great deal quicker.
---
Yes, and I've used Dymo labels. So what?
The point isn't that some panel marking methods are cheaper than
others, it's that, basically, your hex "solution" won't yield the
results the OP asked for.
---
Laying out a board to create a single protoptype can be worth the
effort for very high speed electronics. For this sort of work a one-
off prototype is usually hand-soldered onto perforated prototyping
boards. You can wire-wrap the connections but I've not seen it done in
recent years.
---
Oh, well...
If I don't go directly from schematic to PCB that's exactly how I do
my prototypes and one-offs. Vector T-44 terminals hot-pressed into
FR-4 perfboard with 0.025" diameter holes on a 0.1" rectangular
grid.
Components are mounted on the forked side of the terminal and the
connections wire-wrapped on the other side of the board. For
high-frequency stuff I use single or double sided copper clad
perfboard and spot-face a 0.1" diameter space around the terminals.
Works great.
---
If you've got access to a printed circuit layout program
that can do auto-routing, creating a printed circuit layout can be the
quickest way to get to a working board, but going from gerbers to
etched boards takes a certain amount of organisation which a
mad.scientist might not be able to access.
---
Again you digress.
---
In case you hadn't noticed, the defects in your banking system
recently produced dramatic falls in every stock market around the
world. That gave everybody a lot more trouble than any comment I could
possibly make.
Try and vote for somebody with an ounce of sense in the next set of
presidential elections.
---
This is supposed to be a technical discussion, not an outlet for
your anti-American garbage. You really do have trouble staying on
track and you never miss a chance to spew vitriol, do you?
---
What the client thought they wanted, not knowing what alternatives
were available.
---
You grasp at straws, Sloman.
The client described what he wanted to achieve and presented a
couple of ways he thought would get him where he wanted to be.
Your cockamamie hex rotary switch "solution", LOL, cannot by itself
a decimal display make.
---
While your approach might be described as the electronic equivalent of
the vanity publisher. Flattering for the client, but scarcely offering
them the kind of service they ought to be able to expect from someone
skilled in the art.
---
LOL, I'm prepared to provide the OP with schematics for either or
both of the two 32 channel switch systems he earlier showed interest
in, (one of which I critiqued in order to show him a better way)
while all you're prepared to do is flap your gums about how he
should settle for hex switching and learn to interpret a,b,...
---
Myopic I am - in one eye. The other one has mild astigmatism, which is
why I've still got binocular vision. Whether I'm an idiot or not is
not a subject on which you are equipped to express a useful opinion.
---
In my opinion, your opinion as to whether or not I'm equipped to
express a useful opinion is flawed.
---
Yesterday's job interview went well enough to show I don't look like
an idiot to people who do know something about electronics, but then
again I've always done well with the engineers at Philips - it has
always been the personnel department that has been unhappy with my
qualifications.
---
Too bad you're so easily outwitted and made to stand outside the
gates, cap in hand, by the morons in the personnel department.
Seems like after all these years, if you were any good, you'd at
least have _some_ internal engineering contacts who were aware of
your massive talents, wanted you on board, and could lean on
personnel in your behalf.
