Hello Chris, > > The C.Eng requires a degree, More to the point a suitable degree from a > recognised university. > That's just one of the problems. Here in the US they often require ABET compliance of your course work. For many older engineers that is not quite possible because even top notch universities didn't have some ABET cert 20+ years ago. Also, you'd exclude pretty much all foreign universities. That is hardcore discrimination and can (and would be) litigated. > You also need three supporters who are also C.Eng and are prepared to > sign off on your work experience. > That's the 2nd problem: There is no critical mass here. The classical chicken and egg situation. I know a whopping two licensed engineers but both in the wrong field since they are civil engineers. I don't know any licensed EE personally (ok, if I make it to one of Jim's parties some day I would know at least one) and have never come across one in my work.

I think he would only need 3 bits of a simple PLD to pull it off. My first thought was that the edge of CF and program catches the revision, but it is the rising edge which means by the time that happens the FPGA is alread brain-dead. He just needs to capture the two rev bits in a pair of flip-flops and needs something to toggle program/CF and he should be good to go. If he's got a PLD already on the board for something else, this circuit could go int he corner of the PLD.Article: 95252

No idea. But I have a hunch that it was in the basement of my late

nobody else was keen on tech books. When I find it I'll post.
The other one is: Hanfland: "Der Neuzeitliche Maschinenbau", 1929.

That is clearly a trend. I have seen folks move to places like Arkansas. Nowadays the means communication are so excellent that it doesn't really matter where you design stuff. There are clients that I haven't seen in years but it never mattered. The upside is that the move to a rural place can provide tranquility, less stress and a re-focus on what the real values in life are. Plus there is some great Americana to be found that I sorely miss in the cities. Saloons, country music, a "real" main street that doesn't fall dormant at night, people have time for each other, people help each other, after a while you know almost anyone and they know you, and so on. And nobody cares whether you drive a snazzy ritzy sports car or not. In fact, all you might need is a pickup truck (to haul some farwood from them thar forest...).

That used to work in the UK, but ONLY for those who worked in places like
British Aerospace, Plessey, GEC, British Telecom, British Rail and the
like. How many of those still exist or have that many people working on
designs anymore, let alone ones with time to do mentoring and sign off.

The situation is that the questions and experience get academic orientated
rather than practical orientated, as the majority of people who have time
to sit on these panels are usually
1/ Academics (even less os these days)
2/ Retired members
3/ Staff from large organisations that the organisation
can afford these staff time to do this, usually because
they are of little other use.
4/ Occasionally relevant people in the same field(s) with
RECENT experience.
The same is usually of the committees, boards and other working parties
for most professional societies in Uk and some around the world.

Most require you also to write some form of academic paper, when ever
I have enquired.
Having never KNOWINGLY worked with any C. Eng or Eur. Ing, but in or
with many companies in the UK, I do not see them as relevant. Especially
any time I made enquiries about these sorts of 'senior' level of membership
they never can find people who can cover the breadth and depth of my
experiences which have been parts of medical equipment, various research
areas, plant control or monitoring, broadcast video electronics, and even
some comms devices.
