I'm tapped out. Too many late nights at the work bench. Your help would be appreciated.

  • Bobbin ass'y is going together nicely. Thank you all for your comments. I'll be taking this video down shortly to reduce the clutter and focus on the current state of development. ZFF.

  • hi, how about a telescopic arm for you bearing.

    thank you for sharing this project.

    good luck

  • I think I'll just assemble the arm in two pieces for now. Shouldn't be a problem.

  • Can u sketch out how U will attach the arms? When u push by hand, U R moving more than 3mm cause of the lever. But,lever makes it efficient. If lose leverages, may b hard to maintain good energy levels. The pivot point and counterweight of the stator is important, as I believe many have failed in this respect.

  • Stator needs to travel about 3mm. Mechanical ratio of the lever alone where I have the fulcrum now is 2:1. Bearing will need to travel 6mm.

    After sleeping on it, I think for testing I will use copper wire, lay it out straight like RR rails, cut small pieces and bend them at the tips to act like RR ties and also stand it away from the bobbin core, solder them to the rails and wrap the whole thing around the bobbin last.

  • I was thinking that the coat-hanger wire isn't deep enough, but if you take two pieces and solder them side by side, that might give the depth that you need. In fact, you can make a circle as well after the desired shape is obtained.

  • Actually, that's not a bad idea. I think even solid 12 or 14 AWG copper would do. The outer bearing race is a bit more than 1/4" deep. What I will need is a way to suspend it rigidly away from the bobbin center that doesn't interfere with the bearing riding along it. Maybe I will use copper and solder small standoffs. I'll sleep on it. Thanks!

see all

  • suggestion 1. lose the bottom lever assy 2. extend the top & bottom of your seagate magnet over and under your rotating disk using iron strips . use your magnetic shielding tape on top & bottom of your rotating magnets to time your seagate magnet 3. balance your arm (maybe counterweight) to middle position and add springs (ballpoint pen) at counterbalance (may need damping) . This based on your you-tube 1-10 Thank you Zero Frozen chosen

  • why not use a elctromagnetic generator and the base and a simple trigger to power a electromagnet to pull the arm down and have a spring to return it quickly enough then you could adjust the timing and way less drag.

  • How about a strip of sheet lead. It can be bent by hand and could last long enough for proof of concept

  • alternative... use a rc helicopter model size flexibelt on a gear wheel below the main rotor..the belt can go of to another gear set at 90 degrees which can turn a cam to push the lever up and down..simples is best

  • You could use bondo you could add and subtract for the cam. I have been working on the same idea sence 1997. You have made great progress. You can get bondo at napa auto body filler.

  • If your still looking for the idea for your bobbin, get another pvc pipe that's the next size bigger than the one that you are using, cut the grove out with a dremel then cut off the ends of both sides of the pipe to the with of the bearing and fit them over the smaller bobbin pipe.

    Good luck!

  • you may need a second disc,

    ie, 78 size disc, on top.

    with magnets,

    spaced. in slightly different

    timing position,

    ahead to push the leaver magnet

    down, after the bottom magnets on the bottom disc, pushed the leaver magnet up.

    pushed the leav

  • ps, the timing, would work out.

    speed synchronizes.

    the little kicks, of the leaver,

    from mal

  • an old 78 record disc,

    under the rotor, spinning .

    on the edge little magnets, north south alternating.

    face upwards,

    the arm, you push, with your fingers, could be pushed

    by magnets, repel and attract,

    centrifugal, force maintaining the spin, the disc, under the leaver magnet. maybe work?
