    Luc, All that playing around I did tonight and I forgot to try hooking up an Earth ground. Did you ever try that yet? (Sorry I just now am catching up on reading here and I see you already tried and answered that ) Also I assume you saw mention of this on OU - an oscillator that "typically draws only 1ma from 5v Supply.
    Requires only 1 external resistor and capacitor to set frequency.
    Can be used as VCO.
    http://cds.linear.com/docs/Datasheet/1799fbs.pdf "

    Sounded good although if your CMOS 555 only needs 300 microamps that is probably even better.

      HI LUC & ALL,

      using my newly wound toroid (which i still think may not have enough turns on it, but we shall see ) i managed to get a reading of -0.5 mV on the resistor across the caps of the input...however as this was happening the voltage on the supply cap was still dropping but very slowly.

      bare in mind this is all using an IRF740 mosfet

        I made lucs coil, it took like 2 hours to wind that toroid I will say that it does seem much more responsive to the influence of anything put around the coil, like magnets. Even my hand seems to influence the resonance of this coil, very sensitive. Unfortunatly my function generator is broke and needs repairs Im still not seeing the cap charging using my 555 circuit and the new coil.

          Hi all

          been playign all day, scanning through a bunch of frequency ranges using about 50% duty on a 555 circuit with "fixed" duty cycle...

          my "LUC" coil is a toroid the same dimensions..with two lots of 5 wraps of 26 guage wire.... inductance without magnets is 4mH.with mags goes down a lil.

          I used the LC calculator and together with the 220pF output capcitance of the IRF740 and it gave me a freq of 178KHz... i tried this...and still cant get the input draw down or to go negative like i could with my normally wound toroid ( which has an inductance of 29mH btw )

          just tried the normal toroid again..cant even get that to work, with or witout magnets at whatever frequency..

            Hi everyone,

            I had a little free time while my son is visiting his mother and made a new video.

            However, it's not showing any over unity

            Sorry this may not be what we were hoping for.

            Let me know if I'm missing something.

              Sorry to hear that -- I can't yet see the vid though - says 'not processed yet' whatever that means. I cut the middle out of my 10 pound torroid which had a metal washer and epoxy resin in it. I'm thinking of wrapping over the top of the existing winds and doing either bifilar or trifilar - maybe even quadfilar. I do think you are onto something here and have always felt torroids - especially bifilar have potential for OU. I saw a paper titled How to Build Solid State Electrical Over Unity Devices by Bill Alek this morning showing a torroid he calls a class 3 over unity device.

              Do you think winding bifilar (which I believe introduces scalar wave potential) might be worth trying with this?

              While waiting for your vid to show up I saw another one using a flat torroid coil with magnets on both sides (N-N) facing it. He had 3 magnets spinning by the coil also and when holding a pickup coil near the setup to run some LED's the current to the setup actually went down.

              Don't give up Luc - I'm sure there's lots of things that can be tried with this setup that may click into the right combination for some FE.

                Luc,

                Its been a pleasure watching the experimentation and adaption of your thoughts and ideas. I'm looking forward to seeing you progress into the MHz frequency range with future endeavors.

                The Road Not Taken by Robert Frost

                Two roads diverged in a yellow wood,
                And sorry I could not travel both
                And be one traveler, long I stood
                And looked down one as far as I could
                To where it bent in the undergrowth;
                Then took the other, as just as fair,
                And having perhaps the better claim,
                Because it was grassy and wanted wear;
                Though as for that the passing there
                Had worn them really about the same,
                And both that morning equally lay
                In leaves no step had trodden black.
                Oh, I kept the first for another day!
                Yet knowing how way leads on to way,
                I doubted if I should ever come back.
                I shall be telling this with a sigh
                Somewhere ages and ages hence:
                Two roads diverged in a wood, and I-
                I took the one less traveled by,
                And that has made all the difference.

                  Hi ewizard,

                  are you going to use that core to try to replicate my effect?

                  Can you post the link to the video using a flat torroid coil with magnets on both sides (N-N) facing it.

                  I have not quite given up on this but did loose some drive

                  Thanks for your support

                    Hi luc,
                    Well even if its not the desired effect you were searching for, its still pretty cool that you were able to get as far as you did. I havnt been able to get the effect and as far as i know, neither has anyone else. You have some excellent tuning abilities. One thing that i was thinking about that may improve the effect is increasing the Q factor of the coil. There are various websites about calculating q factor for tank circuits. Sorry i dont have any set instructions for how to do this but i believe you can increase the q in parallel resonant circuits(which is what you would be using with the pulsed dc) by adding capacitance in parallel with the coil. This should get more energy sloshing back and forth in the tank and maybe that might "couple with the environment better". Just an idea, may well be wrong. Maybe someone else can comment on this.

                      I did try that core and a couple other torroids today. The only one that produced anything unusual was the one wound similar to yours (but with much less turns). I found some unusual scope patterns again very sensitive to the magnet position - one at around 250 Khz. It produced a square wave that was offset from the main one and inverted from it. I took a pic and will post tomorrow. But the cap still slowly runs down - I've only been charging a big cap briefly and then running from it. Also today I used a different MosFET as I think I may have blown the other one (not sure yet). The one I used today was an IRFZ42 which I found in a UPS I'm stripping.

                      I think this is the video you may want:
                      YouTube - Magnet Motor_Toroidal Coil

                      I found this interesting as I've noticed several people lately focusing on bifilar pancake coils - an interesting post today on OU forum refers to one also.

                        I think the large toroid transformer core would be a silicon steel tape core.

                        If you want to replicate my effect you would need a Ferrite core which is very different in behavior than a steel core.

                        Let me know what you think

                        Thanks for sharing

                          I experimented with a spiral magnetic wire wraped with a copper wire. Charging the copper wrap blocks the attraction to the spiral wire core. Charging the spiral core creates a north pole in the center of the pancake and a south to the outside. So we have 4 things occuring. One the attraction to the wire, two a canceling with a charge to the copper wrap and three and four, a repulsive north pole from the charging of the spiral wire, in the center and an attractive south pole at the perimeter for the fourth motive event.

                          • Fascinating video with the 3 magnet motor and the neo behind the toroid also a N pole in replusion, i never thought of doing it that way round.

                            I'm going to to throw this in here, more to possibly generate ideas & thoughts rather than anything concrete to actually "build" ( but hopefully though )

                            We've all played with magnets, for example, trying to push two like poles together and battling with it... notice.that as long as you keep the two centres of the two magnets youre pushing on....in alignment....and with enough force, you can get them to connect.

                            However, while trying to do this, im sure weve all applied just a tiny lateral force to one or other of the magnets, thus the centres are no longer lined up.and what happens?.......due to the pushing force youre applying, the magnets shoot past each other.

                            Due to the properties of flux lines, ie- they can never cross and they must always be parralell...this gives them that inherent "slipperyness" that i tried to describe above.

                            with that in mind, consider the following analogy, imagine a razor blade, edge up, the razor vertical so that the blade is horizontal to the floor. Now try and balance a heavy ball bearing on the edge of the razor, pretty impossible.....but....imagine you could do it.

                            Now, since the ball is constantly being acted upon by in this case, Gravity, by applying only a tine lateral force to the ball bearing you can unleash a tremendous amount of kinetic/potential energy ( however you want to desribe it )..and..for the purposes of this thought experiment, i know, to do it all over again you would have to ACTUALLY lift the ball back into place thus spending energy...dont worry...ill come to that part.

                            Is it possible, to create a "magnetic version" of the above analogy... something like... a strong permanent NEO acting as the razor blade,

                            perhaps above that neo with like poles in repulsion, another NEO acting as the ball....both fields are pressing against each other, but because the neos are centrically aligned ( like when you push them together correctly) you could almost say that the top neo is "balanced" on the bottom one..by that i dont mean that the twop neo is suspended by on the field, both neos would in fact be fixed into position on a mount of some sort.

                            now, apply a slight lateral "force" by virtue of prehaps a coil positioned horizontally between the two NEOS ( this would be the same as giving the ball bearing a slight nudge from the side )... and wouldnt the fields of both neos "SLIP" past each other with ferocity like they do when youre pushing them together with your hands..... a pickup coil correctly positioned would picup this flux change..and would also picup the reverse flux change when the trigger coil is de-energised. Notice that in this case, there is no need to spend any energy to "Lift the ball back into place" as the flux lines would snap back to where they were when the trigger coil is de-energised.

                            Hope this makes sense and helps generate some thoughts.

                            • Hi everyone,

                              I made 2 new videos as experiment requests that a user of the OU forum asked me if I could do.

                              The links below will take you to my posts so you can find the details and links to the videos.

                              Sorry to send you there but I'm limited in time at the moment to copy all this.

                                thanks for cotinuing to test :-)

                                could i ask "precisely" which type of IRF640 you have, brand-model etc, as im about to order a bunch of them and want to get the exact same type as yours ( also ordering a sig gen too )

                                thanks,
