    Hahahahaah!

    Something like 6 posts from this loser!

    I must have gotten him REALLY mad!

    I can see the steam from here.....

    Gee, thanks for repeating what i already typed, moron!

    You gave me totally moronic answers to BASIC
    questions, in an attempt to appear to know far more than
    you do, which is not much at all.

    I wonder where you work at....Toys-R-Us??

    hahaa!

    You are misunderstanding me. If the AC adaptor is
    not hooked up, the impedance looking into it may not be
    very high, in which case a reverse biased series diode would
    help out.

    That would be a good idea, to current limit with
    a series resistor, if i expected a complete short, but i
    don't think it's THAT low an impedance.

    Oh, ok, then you meant normally closed when the battery
    is hooked up, and open when plugged into the wall, when
    i don't care about energizing a relay from the wall.

    I'd still rather not do this, but point taken.

    Yeah, i hope to not need even the diode.

    Again, thanks for your input kind sir.

    So many times? So frequently? But even so it it just your and
    Andrews opinion. Shouting about it too hard is much worse than any
    harm this guy ever did.


    ** What BOLLOCKS !!

    Christ almighty - you must be a fucking mental retard too.


    When dealing with retarded, hyper-manic sociopaths - direct action is
    best. A bullet in the head would be the kindest way with raving schizoids
    like " Paul ".

    Hi Fred,

    I'm trying to wrap my head around that topology, but I need a nudge to
    figure out something.

    When the 'A' voltage is removed, the top NAND goes high (1), and sends this
    to the top leg of the bottom NAND.

    What I can't see right now, is how the bottom leg of the bottom NAND gets a
    high (1) signal, so that it will then go to a low (0) output and turn on the
    two FETs to conduct the 'B' voltage towards the desired output.

    I know I must be missing something really obvious here?

    Thanks for any insight,

    Jon

    The battery has built-in diodes to prevent a re-charging
    current.

    What a lucky fella Phil is, as you can see!


    And isn't he a sweet guy, giving her all that chocolate?


    Beautiful!

    Thanks, Fred. Looks like I need to learn a bit more about FETs.

    Thanks,

  20. I gave you perfectly accurate advice on an issue that you didn't
    even know to ask, namely the distinction between USB host and
    peripheral. You refused to take this on board, you launched into
    your vitriol immediately and indeed rejected the whole notion of
    any distinction, insisting that both devices were identical. Don't
    bother to deny it, the details are in the Google archive for anyone
    to see.
    Well, I never advertise. Nor do I even have a web site. All my
    work is either repeat business or by referral and I'm still in the
    position of turning down a fair proportion of work offered. Doesn't
    that tell you something?

    As for my clients they're principally manufacturing or engineering
    operations. I'm working on, modifying or actually designing and
    building unusual 'peripherals' on a regular basis. The only office
    based regular I have is a local architect and that's only because
    I have some knowledge of AutoCAD.
