A full floating trigger circuit to turn on the FET can be made for about $10 so that the FET does not need to be tied to a ground reference.
    Would you mind posting a circuit like this or provide a link to an example?

    Doug,

    I should have said something about this earlier.... John really loved mechanical machines, he was very proud of his pulley and discharge setups, he always felt they were the best option for cap dumping, he made the solid state cap dumps to increase reliability of the technology. everyone who is building is following in the spirit of his challenge to all of us.

    Doug,

    I just watched your 3 BLDC casting process Videos, great job!!

    Even if anyone would choose not to use my particular design the process alone is worth a lot. There are so many coil designs that can be made from this and experimented with. I appreciate Paul Babcock for sharing that process. I have been interested in the Faraday disc type generators with the C-Shaped field coils for a while now. There are some fantastic stories about the designs from Otis Carr, John Searl, Paul Brown, and Mark Tomion that I believe may be worth exploring.

    Tom, The mechanical cap dump has been a fun project to experiment with. There are so many things that you can do with this project. The threaded rod makes additions easy. I wish I could have met John Bedini to have had some direct guidance. I certainly appreciate what information was given through the many videos and books.

    Thank you TomC for that little account in the memory of JB...

    I have added a 15lb cast iron flywheel to the project. The end goal will be to disconnect the primary using the circuit that Bedini provided to Jim Watson for his machines and then zap the primary with the radiant from the generator coils. I'm going to use the mechanical energy from the cast iron wheel to run the device while the primary is getting fed. Here is the video of the energizer running with the flywheel:
    I should have it running with the circuit for preliminary testing in 2 weeks.

    Hi Doug,
    I did some similar experiments on my medium size machine and had some great results. I did not utilize a heavy flywheel as you are doing but the idea of pausing the primary feed and taking from the freewheeling on a genny coil was what I played with along with shorting the genny. I did a lot more after the video I made but didn't tape any more of it.

    If you have a hard time with the 555 circuit you could try what I was doing which is an Aurduino. You can program the duty cycle however you want with those things. I switched a SSR to do the job but you could also use a FET. It's just a simple switch ON (set time) OFF ( set Time) inline on the primary feed. .

    This is a really long video and that was not the primary focus but if you fast forward to about 10 min you can see it.

    Bob, That was a great video and an AWESOME machine!!!! I'm probably digging a little in the past with the 555 and mechanical relay. The Arduino certainly seems to be the way to go. With the amount of amps these machines are said to pulse there is also probably a definite need to parallel your switching devices (relay, bht, fet...etc) even on a relatively small device.

    As for the coil shorting with the reeds to get the high voltage peak events on the generator coils...Is that not hypothetically the same thing as what Watson did using the ring magnets to get the fast switching? Chapter 7 of the Advance SG book explains this. Look under "Other Unique Features".

    Hi Dough,
    First of all Great work indeed!!! Jim Watson's machine was not switched in the sense of Generating the Radiant Impulse in the SSG way... we all know that right!! but nothing stops you from trying it this way either!... i know it can be done.. but the gist of the entire pursuit is.. what is it that we are after..?? either Torque or Speed but not both from the same 'Source'..for me the John Bedini's 1984 machine is more a precursor to understand all this.. (i feel John gave an improvised iteration that was Cap-dump version to Jim watson and not his original 1984 machine based on Tom bearden Theory of self-powered motor-generator.)
    Its not my intention to discourage Experimenters...on the hind sight,..i intend to give pointers in the direction i have gut feeling and that i also have myself getting results the way i have thought about them...
    Rgds,

    Doug,

    Watson was not doing the Coil Shorting technique. on his machine. The magnets / coils just generated a very High Voltage that filled a cap, that was then Dumped into the Primary Battery, while the drive motor is off, (called Back Popping) using a DPDT relay, to switch between the 2 states
    Power Motor / Dump Cap. The duty cycle is a very short duration pulse for the cap dump, and rest of the time is Power Motor...

    Coil Shorting came much, much later, when Kone Head (Doug Kronzen) introduced the technique.

    There is no reason that you can't do coil shorting on your genny coils if you want......
    let me know if you need a coil shorting circuit, and I will show you one with Mosfet Back Popping the Primary battery while disconnecting the Drive circuit......
