  • Hi guys got a lil time to play with my pick up coil or piggyback coil on
    my ss Bedini today. With just a bridge rectifier connected to the pb coil
    I get 40V dc off the bridge rectifier.
    But when I connect a transformer in parrell with the pb coil
    I get 130V dc off the bridge
    when I connect a neo to the secondary to the
    transformer I get 185V dc off the bridge.
    And charging a battery off my ss at the same time.

    Am I collecting BEMF off the transformer back to the bridge rectifier?

      If relate output current with impedance:

      Then added the fact that capacitor will draw a lot less current when it is full, then we can assume that in order to get matching impedance between the coil and the capacitor we need a rather high impedance coil. Maybe the order can be 100 times more than the coil we use for 12V battery depend on capacitor capacity.

      Sorry for late reply, just notice it today. I think:
      - low impedance coil if radiant is recovered to battery
      - high impedance coil if radiant is recovered to capacitor

      Interesting, what happen if you add neo to opposing side with opposing pole?

      • Hi All.

        Here is an interesting video with a home made timing "torch".

        • 8ft wheel

          I am considering making an 8 foot wheel for a bedini motor this winter. I know from other people's posts that the larger the wheel the more magnets they can get by the coil per second. Mainly because of reduced torque requirements. I know that size wheel will take about 100 magnets with 2 inches between them or 75 with 3 inches. Any ideas?

          I was inspired by the idea of a water wheel turning without water.

          • 8 foot wheel

            that is a good idea. I have heard of 4 foot wheels. with a coil as big as a paint can. 200 circuits with a common trigger. here are some tips

            match your coils impedance to your primary battery impedance
            use solar in the day, match the panel to the current draw of the energiser when tuned plus what is needed to charge it for overnight running
            run the solar panel unregulated (no charge controller) or get ready for the charge controller coming from John soon.
            mass at the rim and at the center, with spokes. only 3 needed.

            • The most important thing when designing a magnetic wheel is keeping the spacing between magnets the same. Then comes bearing quality. All else falls after that.

              Magnetic wheels do inspire the makers, that is for sure. You could possibly make some M.C.Escher style waterfall with the Bedini wheel as the water paddle...

              Or transfer the force through another wheel like gearing.

              • Radiant and Solid State

                Hi guys,

                After some tests I found best charging from my Radiant Charger (p.47 FEG)with spare windings in parallel before the bridge, than neg. pulsed with 555 and SCR over charging battery. So, right now I have three windings in parallel. I aso made a short clip of my Solid State -
                Please ignore the noise in the background, it originates from my Radiant Charger sitting on the same bench.

                  About the cost? How about approaching magnet importers, and say
                  that you work is likely to end up a cult YouTube item. Offer to put
                  their name on the side if they send you the magnets free of charge.

                  If you succeed, it will be the best money they have spent.

                  • magnet4less.com has the same magnets that Rick sells with his kits. They are 1.95 each standard price with several levels of bulk discounts. as low as 69 cents each if you order 800. I'll be checking other vendors before I make my order. Pretty good idea about seeking paid sponsors though.

                      I am not sure that this thinking is right. The speed between the magnets is crucial because,
                      I think, time must be allowed for the inductors to shed their load (the circuit's LR time constant).

                      If you want to up your power, maybe you should stick to the same size
                      wheel, and put more bifilar coils around it (each having its own electronics).

                      How would the output of these new coils be fed to the same battery without causing some sort of interference?

                      • It's strictly a novelty item. But who wouldn't like the opportunity to see a giant wheel that is capable of desulphating the largest of batteries over time.

                        I figure worst case senario is i get a few laughs out of a hand full of people.

                          It would look great. I think you are preparing a presentation to

                          Now, that's what I call a potential Bedini SG.

                          Stepping back a pace, how about an SG with rather more coils,
                          in fact, one less coil than magnets?

                          • Flywheel effect....

                            I was hoping that a larger wheel with proper magnet spacing and additional coils would be able to take advange of a mass flywheel effect and provide additional tourqe for shaft output to run a generator....

                            Any thoughts?

                              this would be moving in to the Bedini/Watson territory. An interesting move.

                                A bigger wheel will give more torque. Much like putting a longer handle on a ratchet to loosen a tight nut. But you are sacrificing rpm to do it.

                                It you are goin to be spinning that fast make sure your magnets are secured. the farther away from the axle they are the stronger your glue has to be.
