    Patent #US7990110 FIG.1 - Replication

    Greetings Friends,

    I have a new board to share with the group.

    This is as close of a replication of FIG.1 in Mr. Bedini’s Patent #US7990110 as can be obtained with automated switching. Mr. Bedini’s diagram is meant to explain the process of obtaining a spike and mechanical switching is represented. I have replaced the mechanical switch with a FET and a micro controller but no other additions have been made.

    Here is a picture of the board:

    FET_1.jpg

    The coil is fed at the “top” end from the primary pos.
    The “bottom” end of the coil connects to the drain of the FET, the source of the FET connects back to the primary neg. This is our switching point and it creates our closed loop.

    Extended from the drain we have the anode of the diode connected and the cathode connects to the charge Pos. This is where the spike appears and is our open path.

    The charge neg is connected to the Primary Pos.

    I have a 75V Neon across the charge POS/NEG which is not necessary for the circuit. It is only there as protection and as an indicator.

    The Gate of the FET connects to the microcontrollers logic signal (5v 20ma) through a 150 Ohm resistor. There is also a 10k Ohm resistor from gate to source.

    The switching is then controlled by programming the microcontroller with ON/OFF periods of the logic signal. The power source for the microcontroller is external to the circuit; I use USB battery phone charger to power the board currently. The estimated draw for the triggering is about 40ma; 20ma out for the signal and 20ma is used up by the chips onboard.

    This circuit is exhibiting some very interesting properties which I have not seen on other builds. For example it self adjusts to the load!

    It feeds the charge battery at precisely the correct pace to achieve a perfect charge, simultaneously self adjusting the draw from the Primary.

    As usual I have a video for those who wish to see more:

    Excellent vid!! Arduino are so great to use! this is an easy replication. you can get arduino from Fry's electronics, and other online retailers.

    Thanks Tom, appreciate the feedback.

    I have another short video to add to the thread here. This demonstrates running a load from the radiant side while charging a battery. In this case the load is a cooling fan for the FET.

    By the way when I watched these videos I notice I sometimes say Primary when I mean Secondary, anyway you guys should be able to understand what I am showing even with the mistakes.

    Here is a bonus video:

    Bonjour.
    Est ce que par exemple, le circuit peut fonctionner a partir d'une source d'alimentation fournissant 0,7 volts pour recharger une batterie de 12 volts?



    Hello.


    Is for example, the circuit can operate from a power source providing 0.7 volts to charge a battery of 12 volts?
    Regards
    Pour moi, le principal, dans le fonctionnement du systeme Bedini, est l'energie rayonnante (temps 7) laquelle a pour but de recharger la batterie primaire.

    Comment amplifier cette energie afin que la batterie primaire soit totalement chargée?



    PS: I do not understand the american's language.
    I call a google translation to try to communicate with you ....

    NO ... The Primary is 12v,, charge also 12v

    Bonjour

    Merci de m'avoir repondu aimablement.

    Quelle sont les depenses de la batterie primaire lorsque la batterie secondaire est chargee?

    Merci de me repondre.

    Cordialement.



    Hello there

    Thank you for answering me kindly.

    What are the expenses of the primary battery when the secondary battery is charged?

    Thank you to answer me.

    Best regards.

    Thank you to answer me.

    Best regards.

    I need to do many more test runs to determine the efficiency. From what I have seen so far I would think a one to one ratio should be possible.


    I may run some charts on the primary and secondary voltage soon. I have been more interested in the frequency behavior as shown in the video. ----Thanks

    UPDATE:

    I have decided to take the fan power from the primary side, I will explain the issue I ran into.

    It did work well as I described but I found as I tinkered more with the machine and put different batteries on the charge side the effect would vary. I did start seeing a draw very slight but still it was there on the primary.

    For those who may want to tinker on their own I will explain in simple terms what I was doing to achieve that radiant power draw and charge at the same time. I had adjusted the resistance to the fan so that it would not spin until it saw about 15v. The spikes are coming in on pulses so what it was doing in theory anyway was being pulse driven off only the high potential spikes, in other words the off period the charge battery alone did not have enough voltage to drive the fan. In comes the spike and gives the fan a turn.

    It did work but tuning is problematic. I charge many different batteries of differnt sizes so when I started charging different batteries I adjusted my timing and it was not stable anymore. Perhaps in a static setup where nothing changes you could drive things in this way, it was a good addition to experiment with but because I adjust things a lot it was not going to work how I wanted over the long haul. I have now just hooked the fan to the primary with resistance so that it does not pull to much, I estimate about 50ma.

    I have a charge curve to share with the group.

    This is a 9v Ni-MH battery, the small kind you use on multi meters and smoke alarms. I wanted to show that this machine when properly tuned is capable of charging everything from the large deep cells down to a tiny little 9v and does it well.

    Here is the chart:

    And another short video taken while I did this run:

    Greetings,
    This is version two of this design. The first one was meant to be a prototype and as faithful to the FIG 1 diagram as possible. This new model is expanding on what was learned.

    This model has two separate coils of 14AWG @ 40ft. The tops are connected parallel to the primary POS and the bottoms go to separate Diode/FET configurations. Each bottom connects to its own anode/drain. Then on the back end the cathodes are bussed together and connect to the charge POS. (See picture). In a way the whole thing is parallel but not really because the FET’s are each handling a coil before the parallel bus.

    I used some larger heat sinks on this build and mounted diodes and FETs as a pair on each. Heat is not an issue with this system unless driving it pretty hard which I have not needed to do. I did when I was first finding its proper tuning however. I still have the fan on the board and continue to hook that to the primary.

    Here is a picture from top side:
    FET2_2.jpg

    And this is a front view with the fan removed so you can actually see the circuit:

    *EDIT*
    Added a video showing a 150AH bank on the charge:
