    I used 2 18ga twisted and mine works just fine. I have noticed that any steel will keep it from oscillating, like setting it on a steel bench. Also try swapping the trigger ends and the resistance should be less than 200 ohms.

    Hi 49er thanks for help. Yes I was putting it on batteries which have metal maybe these effect. Regarding coil lenght how much resistance you're using?
    Did you find this circuit better for dissulphation?
    Thanks

    Though I'm sure many coil gauges, ohms, turns, core, no core, will work as well, just need to experiment.

    I'm currently trying to rejuvenate my old car battery that died a month ago, not much luck though, the oscillator may need more strands with a transistor for each strand to push the battery up higher and maybe desulfate more effectively.
    Seems one or two cells of the battery are shorted out from the corrosion, etc.
    I'm going to be running some more tests with this circuit.

    Today I did the coil on 0.8ohms bifilar but still no oscillation. Is there other guys that can share there lenght coils pleasefor 12v batteries?
    Thanks

    Coil resistance

    It is the school girl motor circuit, though with proper coil and base resistor, it self oscillates, making it solid state, this circuit.

    Hi skywatcher thanks for the info. Regarding pulse coil you're saying 0.6ohms from start to end? and how much is the trigger?
    Thanks

    hi skywatcher,
    can you give me details on the coils specs , i have ssg with motor but want to do SOLID STATE , how many turns , ohms gauge, bifiliar with what 18g and 22g core or without core ..

    Like i said, it seems more difficult to get any good output and reliable oscillation with the 2.4 volt AA series charging the 1.2 volt AA parallel setup, though works ok ,since those batteries don't need much to charge.
    Though if you use 24 volts input, charging 12 volt, you should have no problem getting oscillation and good charging rate.
    So your doing this with a motor, i see.
    Mine is solid state, so yours may behave different.

    Hi Skywatcher I am using about two 12v batteries in series although one is not that charged to another two in parallel. No not to a motor but to an SSG.
    What solid state schematic are you using not Bedini SSG?
    Thanks

    Maybe try lower base resistor or adjust it.
    It's possible when using 2AA's in series charging 1.2volts or 2AA's in parallel, that a sufficient low ohm is needed with enough inductance in bifilar to get enough current flow to start oscillation.
    I noticed this when trying to get the circuit to work reliably with my 13.8 volt power supply and it goes in and out of oscillation with 12 volt batteries in charge position, since only around 1.2-1.5 volts is energizing the coil.
    So it seems a little more tricky to get reliable oscillation and much current flow through when the voltages between batteries are so close, so in that case, lower ohm bifilar coil may be needed.
    hope that helps for now.

    Thanks Skywatcher for response; so I have to make a new motor cause all my motors are about 6ohm coil

    I tried again on this with exact placement of batteries but cannot get oscillation even when shorted Emmiter and collector for a little.
    How much resistance coil are you using guys? cause mine is about 6ohms.
    I have another bigger coil motor but this I had modified it a bit with two resistors to self oscillate maybe this I have to dismodify to work.
    Ok if there's any help I appreciate.
    Thanks

    I'm using an NPN 2n3055.
    It probably can function like matts T. switch, though more tests would have to be made, though that aside, it works great as a battery charger and at rejuvenating, the normal pulse of current mixed with the radiant spike afterward seems to work very good on batteries.
    Hope that helps.

    Thanks SkyWatcher! Yes that helps, although if anyone has any further information like the inductors' used, that would help a lot. Tomorrow is Monday and I'll start my experimental build.

    Wishing you all good "luck," or rather, God's blessings to be with us all -- as I believe mankind needs a non-fossil-fuel energy source right away!

    Thanks to SkyWatcher for bringing attention to this thread.

    I find this thread to be very interesting, and I'd like to contribute in some way. Would like to do the build that Hob outlined, and that SkyWatcher and others have built and graciously reported on here. Great work, guys!

    Can you help with a few questions, please?

    1- What are the inductance values for L1 and L2 -- and are these air-core, or what? (does it matter?) wound bifilar, or single-wire?

    2- Are D1 and D2 simply 1n4148 diodes?

    3 -- what is the resistance of R1?

    4 -- I'm surprised there is no cap in the L2-R1 leg; anyone tried a cap there?

    5 -- do you start with some of the batteries partially charged?


    6-- What transistor would you recommend? (I assume that this depends on other elements of the circuit; I'm interested in BOTH the AA-battery charging circuit, and the 12V-battery circuit)

    Any help would be appreciated. I think this is important, what you're doing!
