Thread: Bedini self running method

  1. #11
    Got the fab work done today but not running yet.
    The mechanical commutator is ready to go with the large timing wheel,
    The silver brushes and round belt, etc.

    I'll start with one, 8 strand coil and switch it manually with beefy battery clips.
    Should have a report tomarrrow.

    Hi All,

    Initial report of Bedini self charging with mechanical cap dump:

    Bike wheel rpm - 370

    1, 8 pwr strand coil.

    120,000 mF cap bank

    10 dump pulses in 8.5 seconds at 21v

    Presently I'm running with a charger on the run batt until large bank is fully charged.

    Then we'll have proper testing prep.

    Always grateful,

    What are the specs for your cap(s) bank?

    Hi Aaron,

    All in parallel for 120,000 is a bit over 1/3 of what John used but is a good start. If you got those to 2-3 volts above battery voltage and dumped that every 2-3 seconds or so, that would be similar to what John did. There is something else that happens with the batteries with those big cap dumps. It wasn't mentioned in my walk-thru video - I want to see if anyone experiences it and reports it.

    Hi Aaron,
    how about using super-capacitors there i guess in year 2000+ photo in his website, i see that he used two cans of 1F each in series.

    Hi Aaron,
    Do you know what John B preferred with the B/C half switch, regarding energy from the circuit?
    As you know there is energy that can be used back to the run batt or switched to another destination.
    I'm looking at doing a B/C half sw with 4 pwr strands and 4 independent strands.

    Thanks,
    bro d

    P.S. One more question,
    In the overview of John's machine, you said that the the coils were both wound in repulsion mode and that they were counter wound.
    Both wound in repulsion mode and counter wound? How can these both be true statements?
    Many thanks, bro d

    To scale this up with B/C half cct, one would need many strands and many coils.
    I've seen 2 examples of John B runing pwr windings from 2 coils with one cct.
    It appears that this is what Aaron showed in the walk through of John's machine.
    My latest attempt is two pwr strands with separate bridge for each one.
    I got more out put with one pwr strand.

    Is a house powered by a bench toy?

    Hi Bro D,

    I have more of the JB Ferris Wheel 5 pnp/npn Transistor B/C circuit PCB's that I Had for sell at the 2019 conference if you would like one to make your 1/2 bridge circuit to drive larger coils, or more coils..........

    Thank you for responding RS,

    I tried the attached cct (board made on CNC router)
    and it put out less than a single half BC cct.
    I used jumpers for the trannys and the R's to make easy changes.
    You might see why.

    Today it seems that to scale the half BC cct up to charge large banks, one would have to use a single BC ct with multiple trannys for higher amp in/out.
    Also coil windings that are equal to #10-12 range. Single bridge.

    I would like to see how you handled the scale up.

    If the best way is to use one of your boards then I'll take one.

    Is the full B/C sw more efficient regarding out put then half sw?

    Thanks,
    bro d

    PM me for transaction info, please.
