    Your build looks very impressive! Nice work!

    From your video I assume the voltage measurement on the doubler is from the Bedini - Cole circuit that is running the window motor? And the energizer is not yet hooked up to any load or battery?

    You mentioned in the previous video that the energizer had a trigger winding on each coil. If this is mechanically driven by the window motor, why are you using trigger windings on the mechanically driven bottom unit? Is this for coil shorting? Or maybe over-driving it as an SSG for more out put? Or for switching a controller?

    I thought the energizer portion of John's 1984 machine was basically a low drag alternator charging a cap through diodes, with a switching controller cap dump to the singular battery.

    I would like that. I should know by the end of Jan 18' if I can make that happen. I will let you know.

    Do you think the rubber bands ran smoother or is that just my perception loss from the video?
    -Patrick
    Thanks Patrick. The problem with the rubber bands is they get really tacky after about 8 hrs of run time. This is especially a problem the further they are stretched. The chain is noisy. The noise can be reduced with a chain guard if properly designed.

    Thanks.

    Yes..from the BC circuit. The energizer is not hooked up yet.

    You mentioned in the previous video that the energizer had a trigger winding on each coil.

    The separate trigger coils will be to trigger the coils at the right time via multiple ssg circuits as per Patrick/Bolt's method : https://www.youtube.com/watch?v=0leZ...QP5Zv9OtA&t=2s

    It seems like something special needs to happen to get the hv events to occur with the energizer coils. I need to run some test for myself to verify.

    Thanks for the link to Patrick's youtube post. I had forgotten all about it and Dadhav's posts on the subject. I didn't understand what it was when first presented. I still don't really understand what's happening, but it seems to behave like coil shorting?

    This is yet another design. It uses the Harbour Freight ceramic magnets. They are doubled up at each of the 6 positions in the NSNSNS configuration. I am using one Trigger wire (26 AWG), one Power wire (23 AWG), and one Generator wire (20 AWG) on this motor. The circuit is a one transistor Bedini SSG. Here is the file: https://www.thingiverse.com/thing:2756600

    Hey DMANN,
    First of all Superb work pal!!
    Does the Generator coil (i heard you say you are using 'coil-shorting'using red switch in the video)serve the same purpose as the Aluminium cylinder in Bedini's Spherical Window motor that runs on the Lenz's opposition mode??

    I made a housing for the motor: https://www.thingiverse.com/thing:2789344 and have some interesting results with coil shorting.

    Most cities have a pro skateboard shop. You can get a pack of ABEC-5 bearings for $20. I added three additional files that will give a choice to use 8mm rod with skateboard bearings. These are better than ABEC-7 if you can spend a little more: https://bonesbearings.com/bones-reg-...earings-8-pack

    I've had an inquiry as to how I wound this latest motor. I found that it was easier to just do a video. If anyone needs any further clarification just ask.

    I did leave out, unintentionally, that the perimeter windings will be tied together in series to where they will pulse all six magnets poles in the same direction (either push or pull). Power the window coil up first. If, when you power up the ssg coils (perimeter coils), it does not increase in speed, you have hooked it up wrong.

    Doug,

    the orange brackets are they not needed for the build ?
