I guarantee you that if you open up any phone/monitor/TV/camera there will
be at least one custom IC that is not an off-the-shelf part. It's not just
IC makers that design ICs, any company that has a relatively high-tec
product does it. For example we design our own driver and controller ICs
for LCD panels, I know Canon designs their DIGIC image processing IC, I
imagine all other camera and display makers do similar. For TVs and
monitors I also assume they design controller ICs, because often there is no
off-the-shelf part to exactly fit your product. What about specialist
electronic test equipment? Presumably FPGAs will need to be designed for
that. How about network cards and routers, someone needs to design the
chipsets for those which are always being improved. What about when
Logitech develop a new mouse technology, I doubt they can just pick up an IC
from RS that does the job. What about the thousands of companies that offer
FPGA and ASIC design services - who are they doing work for? Who is working
for them?

Yes, but this job is at our Oxford lab.

Nope. While most people don't /care/ how computers work, my experience
is that many of them still tend to be impressed when people know.

In the same way I don't regard watching people beat eachother to the
ground over a small, oddly shaped, brown ball as fun.
But, what you're doing sounds fun to me. :)

There is a not insignificant portion of the human race that is aware of
your existence that does not regard you as a loser in the least.
There is a massive proportion of the human race that is not even aware
of your existence. This segment does not count, as they cannot possibly
form an opinion of you.

(1) That's where the "get a qualification or training" suggestion kicks in.
(2) You just named another point why toying around with 7400s may not be
wasted time after all: FPGAs are essentially nothing but a bunch of
(N)AND and (N)OR gates, plus a few flip-flops, that you can "wire up"
programmatically. Once you have toyed around with 7400s and the like,
going for FGPAs is a piece of cake. All you need is a dev tool (some
FPGA manufacturers give you at least some trial version for free) and a
dev kit (which you can solder together yourself in some cases; that's
what I did), and there you go.

At present, maybe. If you keep going (and possibly do some qualification
on it), things could look different soon.

how about it being a practical intro to general chip design?

regexes are definitely useful. :)

plus, if there's ever Armageddon, Andy will be King by getting networks back
online made out of 8-bit chips. He'll get all woman bowing to his supreme
intelect bringing back Farmville and Facebook (8-bit renditions).
Of course, there's first the little problem of getting electricity back and
molding his own sylicon devices out of sand...

Rly?
Clearly I'm going to the wrong sort of parties...

Who needs electricity when there's water pressure? ;-)

...which isn't useful unless you happen to design chips for a living,
with approximately 0.0% of the population does.

...no, I'm not even going to say it. :-P
