    Simple Open-source Random Pulse Amplifier
    A Stochastic Resonator Pulse Supply

    I'm hoping to find a collaborative group to design, test, revise (in
    ongoing round trips for several months) a simple schematic for
    amplifying the random noise of Zener current, and using the random
    noise to switch a power MOSFET (or such) with as narrow a pulse as

    Rather than general chat/antichat on the topic, I'd hope to gather a
    protagonistic group toward a project posted here...

    Or contact off-list mitch @

    So you want a random number generator?

  3. Plus winding details for non-inductive coils. Next week, constructional
    details for capacitors that don't store charge, and superconducting
  4. Lots of big words in the article, but:

    So how much noise is generated by the zener, D2 in draft 1.
    R3 looks like a variable short circuit to me.

    Well, there's much more.
    Probably something like the 7 (hundred) hidden errors and I'm sure Win
    wouldn't have dreamed such a sum of bad ideas circuit.

    Also there's no need for an accomplished engineer to optimize this
    circuit: it's quite an accomplishment in itself :)
  6. It's all utter rubbish.

    The writeup at the URL makes no sense to me. The system which
    contains no harmonic energy, once pumped to a threshold....?????

    Perhaps it would be best if interpretation of the write up is left to
    you, and you just say what kind of pulses you want. Do you want
    pulses of random duration, random time of occurance, or both? Does
    "pulse" connote fixed amplitude -- either "on" or "off"?

    What is or are the random parameters -- time of onset, duration,
    number of pulses per second, or ???? What kind of statistical
    distribution are you after for your stochastic variable(s) --
    Gaussian, linear, or something else?
  8. Thats why I gave up after finding 2 errors. The site also needs to be
    translated into english

    Yes! Thanks, Fred, I have saved the drawing in my bad
    circuits! candidate folder. It's a real douzy! Not a
    good omen for Open-source circuit design, whatever that is.

    I hadn't been following this thread. Bwahahahahahaha!

  11. The text on the site is a typical melange of technical phrases more or
    lest scattered at random. The Maharishi Mahesh Yogi did this sort of
    thing. Once you see the words 'vacuum energy' (you DID see them, didn't
    you?) with no explanation how this 'pulse generator' could affect or
    liberate it, especially via a non-inductive coil, your sc/kepticism gene
    should switch to flank speed astern.
  12. Yes indeed, I was wondering how they are powering this crap, maybe a
    78L15 as a shunt regulator?

  13. Actually, I think it is rather clever. It will certainly
    teach the end users to stop fiddling with the pots ;)

    Hmm, a pot, a small window comparator, and string of 555's
    that turn on crowbars all over the place. And a very inviting
    label near the pot, something like "Spatial Bass Enhancement".

    I particulary like this requirement:
    "Maximum pulse repetition rate through maximizing
    the settling time after a pulse."

    Hi Luhan,

    No, not a random number genertor, but a random pulse generator--white
    noise amplifier. The current peak delivered by the circuit needs to be
    very high and very short.

    A sea shell will "pink" the "white" noise at the sea shore as a
    harmonic chamber.

    The "pinking" influence of various piezocrystal-magnetic resonant
    circuits is the intended use, but the use has nothing to do with the
    circuit design... which is simply to deliver maximum current in minimum
    time to a low resistance device, at a very high pulse rate per second
    (several dozen kiloHertz perhaps).

    The white noise of the Zener current is a nice source of randomness...
    as I understand from my amateur level of electronics. The variable
    potentiometer is "suggested" to adjust the Zener current. The op-amp
    is only a suggested black box that will trigger the MOSFET at various
    "pinking" parameters of the white noise.

    Any suggestion of the errors to be corrected in the "suggested"
    schematic at the link would be appreciated. As noted in the article,
    there are errors, and the request was to suggest improved versions
    based only on the circuit suggested.

    As well, I don't understand the drawing programs, like SPICE, or
    electronic design, and I hope to attract someone that can be the
    project engineer... all voluntary, of course.

    Hi Don Foreman,

    Thanks for your questions.

    The pulse distribution would be as close as possible to being a mirror
    of the randomness of the Zener current.

    A Zener is a quantum tunnel device as I understand it, true?

    The "randomnes" of the source of quantum fuzziness is the character of
    the pulse distribution.

    The amplitude and duration is not yet realized. The project circuit is
    posted as a suggestion, and as such has already weeded out many
    antagonists from well meaning protagonistic advise.

    I understand the Zener clamping diode (spike protection) is backwards,
    true? As I learn details (and perhaps I should be in a beginners forum
    rather that with the august big dogs) I'd hope to link words to
    definition pages... this is toward helping the novice realize the
    design components purposes.

    There is a lot of scientific research outside of electronics in the
    science of system dynamics. Search the wiki
    for "chaos and bifurcation" for various links. A frog's ear uses Hopf
    bifurcation effect to couple with faint sound and ignore louder sounds
    (a faint insect buzz in the raucous din of pond life). A PA system
    turned up to the threshold of feed-back is a course analogy of Hopf
    bifurcation. There is a couple of good articles on randomness
    stabilizing determinant systems in the Esoterica Articles.

    The coupling with the illusive gravity wave and piezocrystals (saphire)
    is a current project in Australia. A friend in Alaska has repeated the
    success of Wilbert Smith of Canada, circa 1950s using piezo-magnetic

    Back to bad electronics... can you suggest corrections for version two,
    with a focus on selection of practical and affordable components?

    Hey Ed!

    You mean the "flux capacitor" (hehehe). That's one bit of psience
    fiction I haven't posted anywhere yet... based on a magnetic array
    technique that will lock two magnetic iron squares together with a
    levitated separation, each have a center hole: a stack of these in
    pyramidal form... sacred geometry and all that stuff.

    There is a patent on a moebius strip resitor that will also crank your
    skeptical-gene... the moebius resistor is actually a circular strip
    capacitor that has a half-twist which makes it one surface, and as such
    has a resonant frequency proportional to the length of the
    circumference... while the capacitance goes away at resonance when the
    traveling wave meets its tail.

    Plus the Caduceus winding is well known outside of consumer electronics
    circles, also patented as a toroidal Caduceus winding.

    Thanks for all the laughs. Back to bad electronics now --and the
    request to help make good electronics from the pool of engineering
    minds in the know... a group thing.

    Tell me how to fix whats wrong, please... the obvious problems first,
    then round-trip through design tests and subsequent versions.


    The measure of the group-project advocate is as to whether when his
    skeptical gene is activated, that it doesn't activate his fight nor
    flight response, and instead invokes a curiousity which overcomes
    sycophantisms aimed at meriting group allegiance with the
    antagonistical and subjectivly ascertained big dogs of the respective
    interest group... I've been doing email groups for eight years... same
    old stuff always happens :)

    You're obviously a victim of severe psychotic confusion resulting from
    some sort of serious shortcomings in mental development. Whatever you
    do, please stay out of politics.

    Your most glaring error is that you're top-posting your replies.
    Learn how to bottom and in-line post if you expect much help from

    Some of the remaining errors are:

    1. With R3 at 0%, VP will be connected to ground through R3, which
    means that you'll need a power supply which can source infinite
    current through the zero ohms of R3.

    2. D2 is in backwards.

    3. There is no such thing as a "0µH" inductor.

    4. R2 and C1 will only slow up the circuit.

    5. Your opamp will "rail"

    Let's separate the problem from proposed solutions for a moment. In
    other words, fuggedabout the zener for now, and define what you want
    in terms of excitation. Might this be pulses of known voltage and
    duration occurring at random times, like random injections of a
    quantum of energy? If so, should they be bipolar or is a DC
    component OK?

    Once we sort out what is wanted, then we can worry about how to
    realize it. There are several ways to get randomness.
    We're all beginners at something until we quit learning.
    It'll be up to you to translate all that into terms of what you want
    in terms of excitation.
    Yes, once you have clearly defined what you want in clear, simple
    terms. The circuit designer need not understand Hopf bifurcation
    etc. It's your job to determine what you want for excitation.
