    Clarence that is a great great idea to use a BFO I have
    always remembered the old books when i did some radio
    way back when. I love all the good old circuits and everybody
    needs to remember as you know, each circuit has a special place.

    Here is a basic description of what you are talking about so our
    viewers can understand what the goal is for the final stage. The
    old ways of heterodyne have been lost so it is time to bring it back.

    You really are going for the best final. Yes filters were suggested
    as we remember when DON S. talked but he didn't go into the
    depths of what that really takes. I think we have our answer now.

    In the most readily available material on the subject the targeted
    final stage is audio but we can't forget that by using this method
    any frequency is possible just as easily. It doesn't HAVE to be in
    the audio range of 20khz, it could be used just as well like you
    pointed out at 60hz.

    Below is a discussion about a lost art of true radio roots.



    The beat frequency oscillator (BFO) i

    Beat Frequency Audio Oscillator

    The BFO has mainly two RF oscillators. One of the oscillator gives a fixed frequency and the other one produces variable frequency. The variable frequency will be slightly different from the fixed frequency. The fixed and variable frequency outputs are fed to a heterodyne or mixer device. The sum and difference terms of frequencies f1 and f2 are obtained as the output of the mixer. It is so arranged that the difference terms of frequencies f1 and f2 lies in the audio-frequency range. All the RF components, leaving only the audio-frequency difference component, are removed in the RF filter. Audio-frequency output is then amplified in the AF amplifier.

    It should be noted that the two RF oscillators are completely isolated from each other. If there is any sort of coupling between them, they will synchronize when the difference is small.

    Beat frequency audio-oscillator has become obsolete now, because of its complicated circuit and Wien bridge oscillator has taken its place, which has already been described.

    Hi Clarence,
    You will have at the output coil both input frequencies as well and some others. It is mandatory to have an output filter where mains frequency can pass only. Else you have genuine transformer function. The frequency generators might be disturbed as well by the other frequency. Depending on their circuit you need to add there frequency filters as well.
    As proof you can see the Bob Boyce transformer where he intetionally mixed the frequencies and applied this complex mix to his hydrogen generator.

    That is better than I thought Clarence. The project
    appears to be top notch professionally assembled
    and I am certain great operation will follow.

    Back a while we were talking about using so many of the TBC
    coils and the TPC coils to generate HF that some speculate
    bounce energy off the ionosphere then returning to be harvested
    in great quantities than when the signals left.

    The problem was that no 60hz loads could be run and that if
    a means to filter out the HF was ever found the new load might
    might throw off the HF portion.

    I hope you can tune it for a balance that will give the extra without
    drawing down the source then you won't need another 120
    earth grounding rods.

    Nice box. It that the big block with a sinc on the other side?
    It really looks pro. It is going to show great results.

    Hi Cornboy,
    My pleasure you surface again :-) :-) Hope you established well at new location. What do you grow now?
    My experimenting is near to 0 and will stay there up to 2018 but will come alive then. Just "sharpening my ax" for that sweet moment.
    What monster do you refer to - there are several in my thought.

    @Bromikey:
    Of course it is essential to not kill effects requested.
    On other hand those effects surface at fast switching and most circuits are not optimized for that. They are operated just like switching a lazy relay. You should be aware that at average current you often switch (unknowingly) excessive peak currents and under this condition switching is lousy -> heat -> you reduce pulse power -> you do not get performance possible.
    What Bedini teaches for SSG is super simple and cheap setup but sophisticated and adapted to that very setup he proposed for proof of concept. Based on that we should learn more being steadily aware that changes shall be compared to previous know good state so it is a good decision to pertain a known state.
    But in case you want to tweak it you should know what levers are there and what they do and what I wrote above is of general use at every transistor circuit. BTW: FET drivers we have similar implications that need different curing.

    Hey Clarence

    i did read up on your progress. John has something on the resistor
    and diode to advance efficiency but it might kill the effect.
    We can't have that now.

    Keep pumping that energy around til you decide you struck a vane.
    yeah that is a great driver circuit to work with. And that block will
    really add a new twist. It is a tool to see what can be done to
    squelch some of that HF aether down to 60hz.

    We got to find the key hole to unlock the final stage.

    2.
    Transistors own a B/E capacity and it needs to be discharged for OFF state in order to get is switching fast and cool.
    A transistor is not FET and hence it does not react on voltage or charge. But electrons from this charged capacitance perform a small current up to discharge state and hence the transistor continues to conduct in a lossy manner.
    At Bedini circuits the reversal of the voltage at control winding performs this discharge and the protection diade at base of transitors drags it down to minus 0.6V. Three or four diodes in series at that location will make things even better. This is another smart thing about this circuit and that is only one of those.

    In your circuit above you do not have those Bedini goodies mentioned above. Hence you need to speed up the transistor by additional means.

    A:
    Usually a 100Ohm resistor is added between B and E (low wattage). It does not hurt because it experiences only .6V but helps for short circuit this parasitic capacitance if 555 output switches to OFF.

    B:
    Yo may add a small capacitor in parallel to the base resistor. As the base capacitance is dependent on collector voltage and bas current it is not fixed and needs to be tested out for the base leg to go not below 5V minus at switch off time.

    C: There are other simple means but I will elaborate on it at request only. Such small measures often make a replication useless if components are brought to their heavy load condition.

    I CAN FEEL A MONSTER coming onn!

    Hello John, good to see you posting again, hope all is well with you and your family.

    Warmest Regards, Cornboy.

    Hello BroMikey,

    Here are the photos:


    The batt that I used to power the oscillator was one that I just Grabbed when I first went to power up my Oscillator and it had just sat around and discharged by itself down to 9.2 volts and I never even checked until after I first started to use it. evidently that is why it was charging up by the 6.5 volts supply from the FWBR. It finally gets up to around 10.99 volts but that's about as high as it will go. would need a higher rectified voltage to do any better.

    After I finished my reconstruction this morning and started the oscillator unit
    with that same battery setup it brought it back up again to the near 1o.99 volt level but thats all.

    curious I did take a 12.17 battery and put it in place of the 9.2 volt batt and
    when I started the oscillator it started dropping slowly and not charging. I didn't wait for it to bottom out because I already know that it would have gone down to 10.00 to 10.99 and then just maintained it self from then own.
    ALSO BRO I did use a ceramic .11 uf capacitor and was actually able to hook the positive FWBR output back to the powering battery positive post making everything looped and just needing one battery!!!!

    all of this tells me that an oscillator/coil system producing high enough acv
    can rectify that AC and use it to keep its powering battery charged while
    driving other light components at the same time.
    and all of this can be done at a very low KHZ by the oscillator but will still have to be in the KHZ range though.
    Any double layer coil system when driven will always produce more acv at a lower KHZ than a higher KHZ using the same damn coil! turn the frequency up and down and measure voltage and you will find out real quick!

    Well, enough of this good stuff, through it all and much learning I now finally
    have my small boxed Oscillator (top off seen in the photos) and its companion signal coil output system to be used in conjunction with my Intermediate Frequency Transformer as the means to eliminate the high frequency in the TBC AND TPC 120 voltage and 240 voltage and have it available at the necessary 60 hz standard household voltage that I have been working towards all this time.

    Best wishes to you on the SPLITS !

    Respectively,

    Clarence

    To keep from tying up your time I will make photos of the exact circuit I am using for my oscillator and showing the FWBR and Led in place - also the FLO
    thru battery and its clips in place. I am going to let it run all night and see what
    the batt reading is for tomorrow.

    Say by noon or so tomorrow.

    regards,

    Clarence

    I meant to ask you if your full wave bridge is HF type? Are
    you connected using that big block? Diodes will act as
    resistors at a HF.

    Hi Clarence

    It is my understanding that all batteries in the pulsed circuit are
    subject to be able to collect energy back to it if tuned right.

    The path of least resistance. I saw the circuit yes. Talk to me
    Clarence. Let me see you in action.

    That is exactly how the SG Osc was born.

    been awhile for certain!

    First I have a question, and then later I will post with a reply to you concerning the question.

    I have peeped at you on the Split Positive thing, not that I intend to do any of that, however I need to know if you have a battery routine with with just two batteries - one of which remains constant ( not even a hundredth volt change at all) forever. the other battery (which is not connected to the one I just mentioned) at present being actively used as a powering battery supply is also self charging itself while powering LED? thin air? backfeed? what?

    Holler soon.

    Clarence
    Hi Clarence

    So good to see you looking over my shoulder. So far i am not
    sure what I have yet. I ran tests on old batteries that seemed
    sort of weak exhibiting very low capacity for their ratings and
    have thrown out a set of new ones that I am trying to get the
    numbers right. Well I got in a hurry and did some destructive
    charging of battery 'C' and normal discharges at super high rates.

    All I have are a set of known good batteries. My new tests will be
    done at a lower drain, running a light and charging battery C at a
    rate that battery C can process.

    I have to rerun tests now that I have set some standards.

    How are your batteries treating you?

    I did finish my oscillator as the photo shows. I also proofed its ability with
    the dual layer feritte square loop transforner ( both units have a blue LED I added as run indicator lights). I just quickly threw together the dual winding
    to see the results of efforts at this stage - the input to the smaller coil was 6.32
    square wave (seen as AC) @ 33.4 KHZ . the output from the larger of the dual
    layer coils was 30 volts square wave (seen as AC) @ matching 33.4 KHZ.


    I will be revamping the dual layer coils to give me a desired output of 120
    volts AC for injecting into the middle IFT coil - NOTE that none of the IFT coils are in place at this time! all good things take time - working on it!


    A note worthy point is the use of the 2N3055 transistor without a heat sink!
    Simply did not need it at this point and I actually don't think it will need one for this low energy level that I will be injecting strictly for the sake of a high
    KHZ signal int the IFT.

    Has taken me many many hours of effort to get it all done this far and more to come I'm sure, but that's life - live it or get to hell out of the way.
    another thing to note is the MINIMAL components used in the 555 oscillator
    circuit I put together. effort paid off.

    Need to take a day off for farm time ( and clear my head) so it's see you later time!

    Respectfully,

    Clarence
    Hello Clarence, and ALL

    since no one trying this circuit!! i will give it a try and see what result came out of it!!
