Fusionchip's Bedini Feedback to Source!!!

Hi Fausto,
just try also to put a neon bulb parallel with your transistor.
When the BackEMF happens the spike should also light up the neon
and thus the spike will go back to the battery via the neon bulb.

( Your circuit might have to be modified a bit.)

This ( transistor plus neon bulb in parallel)  is a trick to simulate a mechanical switch,
where you also have a plasma sparking when you open the switch ( transistor)
and through the plasma goes the BackEMF
current spike back to the battery and will recharge it.

Good luck and happy experiments.

Regards, Stefan.

Just an update. I have the Fan running with the new transistor TIP32A and the new diodes SK3606. The battery has the same voltage as 5 days ago and it is spinning at about 118 rpm. I think current is around 7ma. I dont really know because I had to remove the meter so that I can tune it properly (the meter turns off automatically changing the whole tunning).

I am happy with it except that my battery is not charging up (which is my goal). It is running but too early still to judge by the size of the battery, 100 amp/h little beast.

Soon I will have pictures and videos.

Hi fasto
My test on the big battery is gaining ever so slow . i terminated that test so i will have to condition it with the big bedini for a couple of months . I put it back on the motorcycle battery and boom . she increased a 10 of a volts every 40 minuits or so . You have to have a Very good Conditioned battery . Its not hard to do just charge it only with a bedini and discharge it slow and keep doing this for 60 days or so and then you will have a very strong Bedini Battery . Yea the Ma meter Changes the frequency . i know you can tell what its doing with your scope though .. Its very good at sustaning on a non-conditioned battery i have noticed also except i see gain on them as well just slower. what is the resistance of your Fan No2 ?

@ Gadgetmall:

I just ordered some of those fans from the link you posted.  I am going to give this a try.  They will probably be here in about a week.

Hi all

I've been experiimenting over the last couple of days using a modified 24V fan of the type shown by Goat. I'm using an old wet cell  45A/hr car battery with one bad cell which has been put on a Bedini energiser a couple of times. It is very difficult to maintain the terminal voltage on this battery even on very light loads which is why I decided to use it for this experiment. Any small current draw of a few milliamps over a short period of time shows a reduction of voltage. The trigger and power coil resistances are 19 ohms and the fan has two poles wound bifilar.

Results did not look good at the beginning of the experiment but I eventually found a spot where I could hold the terminal voltage steady over a long period of time and this point coincides with a strange pulsing sound which some of you have described and posted sound files of. I get this strange sound only at this particular tuning point. I have scoped the waveforms across the transistor and battery. The waveform across collector / emitter has a very short duty cycle, thus the low running current which in my case is 20mA at the 'sweet spot'. The battery waveform is very interesting and shows a very high radiant content. My fan is turning at a reasonable rate, so it is doing some work at the 'sweet spot'.

I'm thinking that its perhaps not so much the resistance of the fan windings that's important to get the effect, rather the magnetic circuit and make-up of the fan. I deliberately modified a 24V fan to determine if the resistance is critical and appears it is not. Also my battery is far from conditioned but I'm seeing the same effect as others are describing without the charging. With good conditioning I may be lucky and see some self-charging.

@Hoppy,

oh boy, I am Sooooooooo happy that I am not craizy here and gadgetmall is becoming more and more correct (which I never doubted anyway but it is good to have external evidence).

I am having all sort of tuning points that behave in vast consumption levels. Some will maintain even my SLAs on a long time without dropping voltage. Some will keep the Wet cell battery virtually unchanged and some will simply drain it all.

It is indeed a matter of a sweet point. I also think as you Hoppy that it is the magnetic effect somehow influencing this. I am playing a lot with different positions of a magnet on top of the fan too.

Different transistors will also in a major way change the radiant content. My 3904 is very good but difficult to tune. The TIP32A is very easy to tune but consumes a little bit more. The MJL21194 (if I am correct) and the 3055 are the worse.

I am going to open another 48v fan tonight, take pictures and try a second circuit tonight.

Fausto.
