    Matt

    The bigest CFL i tried so far is 13w.
    It gets bright but its not at full brightness.

    Still working on trying to get the amp draw down more.


    @ shlodo

    I tried rectifiers and they do work very well.
    I ran it from the collector and emitter tho.

    I'll have to try it from collector to base.
    I seen the base of the 2n2222 had a lot of voltage sitting there to.

    use a rectifier to recharge batteries

    @Slayer

    I cant believe it! I just recovered a completely dead 12V 7.2Ah battery with the joule thief! and it holds a load

    Try a rectifier on the base and collector and charge cap/battery, seems to work really well

    will post a video very soon...

    Here's a better drawing of the circuit.
    Xee2 at OU redrew it for me.

    I penciled in a couple spots were you could pick up the - bemf
    Comming off the emitter I get 6v off the base I get 9v.
    This is off a 1.5V AA battery.

    Both going back to negative source for the positive.

    Back EMF clarification

    @Everyone

    Hi Guys, I just want to clarify the back emf issue....

    I know we like to say we are capturing the BEMF however I have been watching the latest video from the "Energy from the Vacuum" series, the new video is called "Teslas Impulse Technology" with comentary and interview by John Bedini.
    Its a great watch i highly recommend it.

    John says its not the BEMF we want to capture. The BEMF is the counter Electro Motive force and is always lower than the pulse voltage (Lenzs Law). Hence, cant get more out of the BEMF than wat we put in.

    Bedini says its the radiant spike that we want to capture not the BEMF. (I think the term BEMF is used in patents to get them through the patent office).

    the coil is energized and As the coil collapses the high voltage spike is sucked fom the vacuum and we can capture it with a diode, like we are all doing.

    He also explained that by putting a bridge rectifier across any pulsed coil will extract this spike (we have been using 1 diode off the emitter). This is the essence of Teslas impulse technology. It appears that on Bedinis larger motors this method is used, instead of the single diode trick from the monopole SSG circuit he released on the internet.

    If u look on my last video in previous page u can see scope shot of the radiant spike.

    Anyway wat do u guys think? Are we calling it the wrong thing? Has anyone seen the "Energy from the vacuum series?


    Also I watched Stanley Meyer lecture:
    YouTube - Stanley Meyer Lecture Part 2

    There is a striking similarity between wat Meyer was doing with his electronics and Tesla Impulse Tech. Meyer pulses dc through a coil (choke) which multiplies the voltage and frequency creating resonance in the water cell electrodes. That is how he is able to fracture water with little amp draw.
    I see this as very similar to the way the Joule Thief, Radiant Oscillator and Bedini motor works.

    wat are your thoughts??

    I noticed it's allso sending out positive BEMF and negative BEMF.

    I have one of my diodes turned around backwards on the 2222 transistor.
    I can connect that to the negative of my meter then for the positive I go back to the negative of the source.

    It seems we can collect the back emf both way.
    When the magnets turning on and when its turning off.
    I tried it, both works. But since NPN transistor usually more efficient than PNP we get better result with positive BEMF. I tried Tos 2N3055 and MJ2955 (sold in pair) and the 2N3055 have brighter LED.

    My previous experiment show that spike only happen at coil field collapse at either BEMF. Try it with a 1.5V battery, a coil and a LED. Parallel the coil and led, disconnect both at either positive or negative side of the battery.

    i do collect it at the Bedini, and coil seems has more power, i lead i back to my plus side.
    I hooked today a scope too to 2 Coils from a JT,
    and both Coils had positive Curves also, only the one had it some earlier.
    Seems, you need a different timing for the other Spike.

    Great Work Gentlemen

    I dont what to tell people what to do but if someone could trying connecting the negative of the charging battery/Cap to ground you may increase the charging.
    Try getting the cap to the highest it will go then connect the ground and see if it goes up More with the ground on.
    If it goes up tell me and I will give a understanding on the process which ends up in higher charging!

    Good luck All

    Hello boguslaw

    The circuits on page 4 Posts: 113.

    But I'd change the trigger 3055 to a 2n2222.

    It seems to work a little better having the 2n2222 trigger the 2n3055.
