  • LUC,

    nicely explained, makes much sense....

    since it seems to be the split winding that is giving the higher inductance, how about instead of 2 split windings.......useing 4 split windings? or 6 or 8? to enhance the extra inductance "effect" on the coil.

    see attatched

      Hi David

      I don't know if that would work but please try it if you can to see what would happen. Let us know of the outcome positive or not so we know what works.

      Thanks for sharing

      • What can it do?

        Hi Luc,

        I find your videos very interesting but may I ask if this effect will charge a battery fast enough to provide power to a usable load?

        What might be the practical use of this device or is this just a learning device and you have plans to move on to something more able to do work in the future?

        Just curious.....

        Hopes and Dreams....

          Hi tjnlsn255,

          at this time most of the energy gained is used to switch the mosfet and an extra 14uA is needed from the source 3vdc to keep the circuit running at 20KHz

          However, it seem that more energy is used in the circuit to keep self pulsing then what is taken from the source.

          So at this time it cannot power anything but we are looking into ways to make it more efficient and maybe find some excess energy.

          I can tell you from the 3 years of research and experiments I have done this circuit shows very promising results.

            re:- my 2 scope shots

            i was only using a pot & the shunt... i wasnt using the 1K above the pot also...so.when i turned the pot all the way down... its resistance....in comparison to the opto's collector/emmitter resistance was small...hence the small voltage going across the gate.... actually....as i turned it all the way down to almost zero....i noticed the signal "flip".......also explains that as i turned the pot up, then the voltage on gate went up....in essence... i had a voltage divider comprised of the collector/emmitter resistance....and the pot forming a voltage divider as i wanted to explore the full spectrum of resistance values at both ends.

            when i switched the scope to "DC"...the ringing went away.....then..the FET blew dont quite know what happened to cause that

              Hi David,

              sorry but I missed communicated something to you of you circuit. You need a 10K or higher resistor across the gate and source of your mosfet to drain the gate to ground when switched off or else it will stay on and blow the mosfet. This is where I wanted you to put the variable pot to see how high of resistance above 10Kyou can go to and the mosfet still switches off. This way you waste less energy on that resistor.

              So again, the pot should be across the gate and source and your shunt between the negative and source with both probe grounds on negative side of shunt. Maybe your 1K resistor can drop some but that was not the resistor I was thinking about.

              Your mosfet is fried. Sorry about the miss communication.

                  • Hi everyone,

                    I decided to make a video using the 2 identical toroid's of test 15 video to demonstrate what I had done for myself yesterday that the magnet affects a ferrite core toroid more than just dropping it's inductance.

                    Below are the scope shot of each at the peak efficiency tuning points.

                    Please note that I had a little bit of tuning problems with the magnet toroid as the efficiency tuning point is super sensitive compared to the non magnet toroid. But I got it at the end just before the 10 minute limit.

                    Link to video: YouTube - Self Running Coil test 16

                    It is also clear by comparing the data of the two shots that there is a gain in the magnet toroid and this is with identical generator gain to each test as I did not touch the generator output.

                    • Well Luc it appears that your persistant hard work is paying off I understand your theory now and it looks promising. Im still not sure on the explanation of the energy gain, but hopefully that will become clearer in time. Comparing your special coil to a standard one was a great deminstration of some actual findings to help us understand what is going on here. Well done! From the last video it appears to me that the special coil has less self capacitance than the regular coil, at least thats one possible explaination for the higher resonant frequency. So working under your theory, i have a question, would you have even higher inductance if you divided the coil into more than two sections. Say maybe you put 3 windings on a core, could you then get three times the inductance. Or maybe 10 or 20 sections on the coil. Or is two the limit?

                      Edit: sorry i just noticed that rave asked the same questions above.

                      • all rings a bell

                        Hi Luc

                        As I posted before, this is very similar to the effects of the STEAP circuit. A polyfase transformer is a four coil as you know, and I could get this circuit to run on its own using another coil and reed switch to do the triggering. I would still like to do more, but I have had to put it on the back burner for now as I have more pressing things to do and so can not find the time.

                        Luc just go back to the circuit that I did with the coil and read switch, this was running and charging the battery, no energy lost, out and back into the battery and power a bulb. A magnet was used in this to set the frequency.

                        Also using a PWM to run the circuit I could bring it into resonance and it would stay there even if I changed the frequency of the PWM, it self oscillated.

                        Dam wish I had more hours in the day, but I am very pressed at the moment
                        keep it up

                          • Hi everyone,

                            Since I changed my cap bank meter to a 10 Ohm instead of the 1 Ohm resistor to get more resolution on my meter I'm getting confused. In my latest video test 16 I said the normal wound coil with no magnet was using 320uA and that is not correct!... it is 3.2uA used
                            Same goes for the toroid with magnet I said it was returning -350uA and it is -3.5uA returning.

                            It will take me some time to adjust using the 10 Ohm but it's worth it as it gives me much better resolution. Maybe I should even go to 100 Ohms!... but I don't have a 1%

                            I also decided to retest the 20KHz self pulse test I posted at OU forum Self running coil?. The more accurate reading is 17.5uA and not 14uA

                            I also took a new scope shot of it once it was tuned to the most efficient and is below.

                            Sorry for the confusion in video test 16

                              Hi Michael,

                              for a circuit to work it would need at least one replication.

                              I did try my best to replicate your circuit from the information you provided me but could not get it to work as yours did! not even close.

                              If you would like your circuit to be replicated and shared, then consider sending it or a working copy of it to me so I can see what I misunderstood and also confirm your results. I will post and share as I usually do.

                              I hope you are willing to consider this as I would hate for something that is working just sit there and collect dust and not reach the ones it could help.

                              Please contact me if you would consider this and I can paypal you the postage cost. I would not need the pwm but would need the same transistor or mosfet you use.
