    Nowadays you're better off using PWM--it's way more predictable.

    I don't have control of the source side... I need isolation, no more >>>>> than 10uA IQ.

    No sure what you want to do here but there are plenty of LED -> dual
    photodiode versions for doing the feedback thing, like this one:

    http://www.avagotech.com/docs/AV02-0886EN

    Thanks, Joerg--I didn't know about those ones.  TI has got completely
    out of the opto business, it looks like, and sometimes a linear
    photocoupler is just the right medicine.

    That might be just the ticket, since I tried this already...

    http://analog-innovations.com/SED/CurrentPolaritySense.pdf

    Pretty puny performance, even when praying that the 4N25 model is
    adequate ;-)

    Phil, Your "PUT" idea is intriguing, though I'd need two for
    _polarity_, unless you have another clever idea ;-)

                                            ...Jim Thompson

    Of course you'd need an isolated power supply to be able to apply
    feedback to the optocoupler...those aren't the same as a dual matched
    opto, where you can invert the transfer curve on the LV side using an op
    amp.

    I'd be inclined to put the PUT device inside a bridge rectifier made
    from two optos and two diodes, so you can get the polarity and the
    current as well.  (That's a variant of Pease's trick with the voltage reference inside the bridge rectifier.)  If you're brave you can save
    one photocoupler, but I'd prefer to subtract the two photocurrents on
    the left side to get a more reliable polarity indication.

    Somebody doesn't put part numbers on his pencil-sketched devices. This might be a whine, if I thought that John Larkin had real parts in mind when he scribbled his sketches. No doubt he relies on his subordinates to fill in the petty details, so it is
    more of a cluck.

    I'd add Genome / DNA to that list.

    Which one? ;)

    Fields occasionally had good things to say, but the interminable

    Most of my interaction with JT was technical. He liked to insult
    people.

    I suspect he drank himself to death. He talked about wine all the time
    and got pancreatic cancer.

    Dunno---he was 78 when he dropped off the grid, which isn't an
    out-of-the-way number. My MIL died of the same thing at 68.

    But you are a bit of a lightning rod at times, you must admit. ;)

    I have ideas, and a lot of people here are instantly hostile to
    unapproved ideas.

    Psychology is important, key to design. It is interesting to see how
    people react to ideas, and even to suggestions of possibility.

    It's not important. It's just a newsgroup.

    Actually they are hostile to bad and silly ideas, and that does cover most of the "ideas" you post here.

    "Unapproved" isn't a a categorisation you can apply to novel ideas - if they really are new (and most of yours aren't) there's no way that they could have got approved in advance.

    Psychology is important, key to design. It is interesting to see how people react to ideas, and even to suggestions of possibility.

    And if you are hungry for flattery, you are frequently disappointed.

    It's not important. It's just a newsgroup.

    As opposed to a group assembled to flatter John Larkin, but he keeps on hoping.

    The discussion/demonstration usually reverts to "you are stupid."

    And the people who "demonstrate inadequacies" rarely have any
    expertise in the subject, which is why they respond to concepts with
    insults.

    These serial insulters are invariantly bad with electronics.
    Interesting correlation.

    You do seem to get a lot of that. Your habit of re-posting climate change denial propaganda and treating it as it were real information is demonstrably stupid.

    And the people who "demonstrate inadequacies" rarely have any expertise in the subject, which is why they respond to concepts with insults.

    Your idea of what constitutes "expertise" is a little strange, and decidedly self-serving.

    These serial insulters are invariantly bad with electronics.

    And John Larkin thinks that he is "good" with electronics. He does seem to be able to fool his customers, and the more expert people he gets to deal with have learned to respect his delusions on this subject (otherwise he won't keep on dealing with them).
    More objective observers credit him with rather more persistence than skill.

    Interesting correlation.

    And it tells us quite a bit about the guy making the correlation, and how he lets his emotional reactions over-ride what judgment he might have.
