As I've said elsewhere, we don't know what Andrew had in mind. Choosing a +5V rail for his single rail system does make the problem complicated enough to be marginally interesting.
As it was when I was working on 4-20mA stuff at George Kent in Luton, back in 1973-6.

I don\'t accept challenges from lightweights, and I _choose_ to do
neither.
If that pushes you toward apoplexy, then so be it.

Just what one would expect from you, hyperbole instead of fact.

Don\'t you delight in seeing the trolls brought to their knees?
I do, and we\'ve seen a lot of them turn tail when dispatched through
sed.
Unusually spoiled brats who\'ve never been disciplined are the bane of
our existence in this world and should be given their comeuppance as
soon as they rear their ugly heads.
It\'s not always an easy task since some of them are smart, like Sloman,
and his parents were, apparently, unable to deal with him, so it lies on
us to apprise him of his failings and, ergo, to help him become a better
human being and the world a better place.

Personally, I think Slowman is mentally ill. His life is built around bickering with people he can suck in here. If everyone ignored him he'd probably commit suicide ;-) ...Jim Thompson

Wow. Chicken-s*it with pretensions.
And delusions of significance.
John Fields does suffer from delusions of adequacy. Here he is posing as a psychologist, and looking even less convincing than he does when he poses as an electronic engineer.

It's just riveting when the S.O.G. [1] and the T.O.G. [2] engage. Sort of like the 45th viewing of a slow motion film of sloths doing battle.

Caught in the Filter Test Folder... it's working to my satisfaction, so you will be ignored henceforth ;-) So happy to note that I can now aggravate Larkin just as easily as Slowman ;-) Larkin's first sign of senility is persistently trying to be an asshole when he is realy nothing more than an amateur.
His second sign of senility is touting his company's wonderful circuit designs as his own, while posting amateur crap on S.E.D
The third sign is acting like Polly Prissypants :-)

Jim thinks he aggravates me, when I'm just laughing at his errors. This lot is pretty good - Jim knows remarkably little about senility (which isn't all that surprising, since he is the renaissence man of ignorance) and seems to think that personality defects are evidence of senility.
Sadly, it's all about short term memory, and there doesn't seem to be much wrong with John Larkin's short term memory - he can remember all sorts of interesting facts, though he doesn't understand them as well as he might.
But he doesn't seem to have reported anybody to the FBI for having dangerously anti--American opinions,
Unlike Jim, who thinks that the MC4014 and MC4044 were wonderful circuit designs.
As opposed to hoping for violent revolution so that he can shoot everybody who is less right-wing than he is?
