    Unfortunately I can't see the picture. I want to try this circuit bellow which said to have 100% variable duty cycle but still never try it yet.

    Havent tried it with optos, just wanna know.
    Maybe, but I don't think I can measure it. If the signal from OFF to ON is important for this maybe we should see the spec of rise time. Here is what I found out:
    PC817 optocoupler rise time = 18 micro second max
    CEF02N6 MOSFET rise time = 35 nano second max

    But would faster rise time is more important than more high voltage exposure in battery charging?


    edit, important fix for latest circuit.
    change the cap to battery to become negative polarity switching conforming Bedini switcher.

    and fix the resistor place.

    Second day experiment do not show self charging effect.

      Another circuit fix

      I still don't get LM393 yet but want to use the the coil in positive part like Bedini mention. Instead of triggering only 2N3055, I use MJ2955 to trigger the 2N3055. This way I can get very short on time for 2N3055 by utilizing short off time of 555. This way I hope I don't experience hot transistor and transformer again.

      Modification now comform with Bedini style, coil collapse by switching of negative side of coil and battery charged by switching negative side of capacitor.

      Charging is faster than when coil is negative part.

      Test report today:
      before turn off:
      battery = 9.63V
      capacitor = 12.24V average
      source = 11.08V

      after turning off
      battery = 9.49V
      capacitor = 11.98V



      Eidt:
      This circuit turn out to be much better than my previous setup in heating property. This circuit transformer and transistor will not heat as fast or as much as previous circuit. Only the resistor and optocoupler that heating up, but this can be solved by using 2 watt resistor and adding heatsink to optocoupler.

      Without capacitor, the battery would charge up faster but the transistor would get very hot even with heatsink, and transformer get hot to the point of it become untouchable.

      The very short pulse of the activating pulse also make the operation a lot cooler.

        My 555 and transformer dies after a week of working 6 hour a day. I decide to use self oscillating relay and optocoupler.

        I get a dead battery from broken UPS for experiment with this new circuit. 12V battery is measured at 0.3Volt ! Using the relay opto circuit the voltage jump to 12 Volt for few minutes. then get lower and lower. After an hour the voltage become 6 volt while charging and 3 Volt while not. Probably the battery cell become regenerated after some few minute of zap of the capacitor and after the cell become alive it demand more voltage to the capacitor and lowering the voltage.

        Because I use no capacitor to control the relay, it do not produce much noise, only buzzing faintly. After three hour the transformer I use as coil do not get hot. I use the secondary part which measured as 200 ohm. I also use neon in parallel with coil to reduce spark. No spark = No heat at relay.

          24 hour a day version

          I forgot that I still don't post my latest circuit update. The key of cold operation is a correct duty cycle and frequency. On my circuit it run cold at 2KHz and about 10% duty cycle. I bust the 555 chip twice only because I accidently short circuit it, so I think this circuit is sturdy enough to be run 24 hours a day for weeks. Although we should take precaution for the battery being charged, whenever the battery become almost full it will heat up and the transformer become slightly warm. I made bump on some 12V gel lead acid battery because I left it charge too long, during 3 hours charging I don't realize that it already full.


          It seems zinc carbon battery is rechargable to some extend as long as you give time to cool it down when it is heating up when charging. Have more success with larger one than small AA. NiCD or NiMg is more recoverable though, seems more than gel lead acid. It would have longer life in one charging.

            similar as the bedini solid state pg 46 charger

            Originally posted by sucahyo View Post
            This is a bit similar to what boguslaw in http://www.energeticforum.com/renewa...-charging.html thread. The difference is the source is normal power source and without coil.

            This circuit purposes is to charge battery using capacitor charge at frequency as high as possible.

            This is based loosely from Tom Bearden design in
            20* Bedini


            There is also explanation of capacitive discharge in Thomas Henry Moray book "Beyond the lightrays". It explain that if discharging is done at spesific frequency it would add up to previous charging and increase the output.

            My short observation result is:
            - It would charge the battery very good but it seems it charge normal electricity. Charging performance is better than Tesla switch, better than Joule thief, better than Imhotep RO.
            - The transistor would not get hot if 12V source used to charge 12V battery.
            - Input current increase proportionally with load / charged part.
            - Capacitor voltage is at 11.12V when the charging battery is at 11.08V, source is 11.16V.

            Both transistor in the circuit should not turn on at the same time. When 2N3055 turned on the capacitor will be charged. When MJ2955 turned on the capacitor will charge the battery. In theory the battery would only draw current from the capacitor, but in reality it also draw current from the source too.

            Maybe what I did is charging the battery directly with source electricity. Maybe the transistor is not capable of switching fast enough and make it just flowing normal electricity at lower amp. The capacitor aid it a little. Any comment?

            Edit: circuit diagram fixed

            Second version of the circuit charge a lot slower but seems to work as expected? voltage of the charged battery is increasing with very little input amp draw at 0.01A.

            Second circuit can also be used to ligth up CFL with the help of car coil. It can output a decent high voltage at secondary part. It also produce long spark as can be seen in this video:

            hi there!!
            i liked your circuits....which one worked the best????

            i made a joule thief charger by using a torroid and it really worked great...also its very small in size....
            i usa a cell phone charger as its source and recharges everything form 1.5v aaa to 12v 7amp ups battery...but its not overunity or even actual radiant energy like john bedini's devices have....it simply gives high voltage spikes at a very high speed with small current....
            wether i build a large jt charger or a small jtc design...it works but i now want to build a bedini solid state charger charging a battery with a capacitor
            which according to john bedini is overunity......
            but i dont want to use expensive components like scr and H11D1 diode..etc etc
            even if its not overunity it can be don...as i am looking forward to your circuits........
            kindly tell me that principle wise your capacitor circuits should work like the bedini one right????
            i am attaching its cirrcuit........
            kindly explain

            charger given in his book " 20 bedini bearden years" on page no 46...


            there is the bedini energizer on pg -46 of his book heres the

            link--"http://www.ziddu.com/download/4732808/zpe_bedini_solidFEG1.gif.html""...

              The best depend on what you want to achieve. The one that I currently use are attached. The reason for this kind of combination (555, NPN and PNP) is:
              - I want to achieve 0 to 50% duty cycle using 555 (said to be colder)
              - I want to switch off the current using NPN (said to be most efficient)
              - 2955 and 3055 usually sold in pair here


              Don't expect to get overunity with Bedini charger. Even Bedini himself mention that this kind of circuit is not meant to achieve overunity. The solid proof way to achieve overunity still not published yet. Using capacitor may help, but it is not the kind of capacitor we can get at store. Same with coil, transistor, etc.

              When using capacitor for charging, you need big capacitor. The electricity generated when the current of a coil being switched off is collected in the capacitor. Once the capacitor is twice the charged battery voltage, it then be used to charge the battery. The problem is the switching mechanism. Relay is too slow and using optocoupler is less efficient (hot). I found that charging using direct way using my attached circuit is much faster and have higher charge.

              I conclude that capacitor charging is less efficient than direct way for my kind of implementation.

              When you switch off the current of a coil you get radiant electricity. But to get usefull charge you need current. High current can be achieve by using coil with low resistance or power source with high voltage. But high current may kill the transistor and 555 if you are not carefull. I use 11.5 Volts power source and my coil around 9 ohm (just from memory).

My attempt is to replicate what Moray said about capacitor can have more energy when charge-discharge at very high frequency. I can't build a high frequency switching at the moment, this is why I use transistor.

                Moray did his device with transistor. I think we should be able to find a way to make OU device with transistor.

                If we can make spark free and high frequency mechanical switch, maybe we can have much much better efficiency. Still waiting for the news from Inquorate which currently trying to build it. Maybe with rotary switch inside oil bath.


                Attached is my plan to make a more efficient charger using a coil. It failed. But it would allow the charging part to have higher voltage than source. The only difference from charge battery with cap circuit is I switching the cap charging. Who knows it can make the battery charge better.

                I am thinking of charging the battery using capacitor voltage only, so the charging must be done when there is kickback voltage. This must be done at high frequency since the kickback is short lived and normal electricity will flow to the battery after that.
                @ Sucahyo - haven't forgotten about the mechanical switch, still working on it...

                I was googling and came across your old post, do you remember where moray said there was an increase?

                Where did you come across that?

                Love and light

                Atoms move for free. It's all about resonance and phase. Make the circuit open and build a generator.

                  Ok .


                  I conclude it from:
                  Thomas H. Moray: "Beyond the Light Rays (Explanation of the Oscillations of Radiant Energy)" -- Radiant Energy -- For Beyond the Light Rays Lies the Secret of the Universe" -- "A Short Treatise on Alpha, Beta and Gamma Ray Therapy"
                  it also available at Free Energy | Dr. Peter Lindemann's Website
                  This I have been able to do through the use of certain oscillators that I have made and of which doctors of science have said are the most powerful devices known to science today. With the use of these oscillators and the oscillating effect of condensers which I have sometimes explained in the following way to those who are not acquainted with the back-rush effect of condensers, and which may serve to make my point now. When an elastic substance is subjected to strain and then set free, one of two things happens. The substance may slowly recover from the strain and gradually attain its natural state, or the elastic recoil may carry it past its position of equilibrium and cause it to execute a series of oscillations. Something of the same sort may also occur when an electrified condenser is discharged. In ordinary language there may be a continous flow of electricity in one direction until the discharge is completed, or if proper use of the condensers are made an oscillating discharge may occur. That is, the first flow may be succeeded by a back-rush, as if the first discharge had over run itself and something like a recoil set in. The condensers thus become more or less charged again in the opposite sense, and a second discharge occurs accompanied by a second back-rush, the oscillations going on until the energy is either radiated or used up in the heating of the conductors. And if your device will oscillate in harmony with the oscillations of the Universe, or in other words, if the device is capable to synchronization with the vibrations of that energy through space then the oscillations will go on forever. No one can call such an arrangement perpetual motion any more than one can call the motion of the earth perpetual motion. My device oscillates because of the oscillations of the Universe.
                  I guess getting resonance is only part of the effort, getting it to resonate at universe oscillation is the goal.

                    capacitor discharge circuit

                    I have a few photo transistors from crt monitors I can use but can not find any SCRS. Would a TL431 serve the same purpose as an SCR?
