Then I would suggest you're working with engineers
who are not
particularly knowledgable about practical electronics. If they're (say)
mechanical engineers or civil engineers, then no problem. If they claim
to tbe electronic engineers I'd probably dispute that claim.
I agree, last year they couldn't even build a set of LED Christmas tree lights
without blowing them up, never heard of constant current drive !!! I'm not
Do you own a suitably large LART?
I must have told the story of the 362.8 ohm resistor. In case I haven't,
it goes like this.
I was working in a lab at a university over here when some final year
engineering student asked me for a 362.8 ohm resistor 'as there are none
in the drawer'. I said that I was not suprised, and asked him what on
earth he needed it for.
Glug! Almost sprayed water on my precious IBM keyboard.!
Even 180 Ohms is good enough driven directly from TTL. :-)
The answer? An LED current limiting resistor.
Apparently he'd taken the
Snip!
I've come to the conclusion that the best
(electronic?) engineers and
programmers are all essentially self-taught. It's probably much the same
in all creative subjects.
Practical experience and hard knocks school is your best teacher
, I agree. Blow up, screw up some stuff as you learn as you go on is
required. Straightening out those mistakes if you can discover is
excellent way to learn.

I wonder if the HPIB spec (if it was ever published)
specifies the
jackscrew threads.
Might be not existent.
4-40 is right for those kind.
