just another note that it will charge another battery  as unloaded produce Ol in the 20 volt scale on the DVM and charged up a 5.5 super cap in 2 mins . Also i have tested Jesus's circuit and it does work ,except i Charged a twin double aa pack and the led gets brighter OR rather stays lit ..I did not do a long term test on his however but i see that it might be possible to bleed some of the double aa power back to source prolonging the run time . possibles .

     Hi . What do you need to know . i posted this 10 20 3050 pages ago . This thread is so full of different experiments it took me two days to read thou them all just to catch up . I posted this experiment with a picture i think . I still have this one . make a regular Jt bi with 40 turns . i used a computer toroid not the large one the next size down maybe 3/4 inch . copper wire . then i took the real thin 32 which is a pain to wind cause you have to string it out first and make sure it does not  tangle .. I wrapped this in between the the regular windings 100 times . it didn't go around all the way . i think if i had the patients you can wrap 500 or more times but i did 100 .. then i wrapped another unused winding that lights an led but it dims the other one .. I used the pots to adjust the bias and frequency to obtain light and positive feedback . you will see that the battery voltage will increase when you connect the feedback up.. Edit .. Dang W"W" Key is sticky . I know how to spell rapped 

@ Gadgetmall:

Please feel free to post any drawings or photos again, or (if you can find it) post the link to the page.  Yes, this topic is moving very fast and deals with at least three different approaches (probably more than that) and it can be very confusing....trust me.....I know this first hand.  So, if you think it can help someone and you cannot easily find where you posted it before, go ahead and repost.  I want everyone here to help each other as others have been helping me. Which, I am very happy to say, that is exactly what has been happening.  Thanks.

i believe bedini showed us best with charging batteries, do not i repeat DO NOT use a higher voltage to charge a battery! it is a false charge!

current battery charging methods send 1.7 volts to a 1.2-.1.5 volt battery, what it sends that recharges it is the amps which does all the work! yes voltage can be funny and drive a light with little to no amps but that is a different principle.

bedini charged his car batteries or lead acids with a +20 voltage spike that had little to no amps to back it. this does not work! it raises the voltage of the battery creating a false positive!

High voltage spikes do help in one area which bedini showed. take a dead battery one that cannot be charged and connect it to a "bedini generator" and you will find that somehow it wakes the batteries up and allows them to function again!

im assuming it cleans the poles of the batteries?

i seen some speak of AC in this curcuit, its not AC as the AC has no way to reverse polarities (the LED IE Light Emitting DIODE) prevents AC. the meters see AC because pulsed DC looks like AC. remember volt meters do not show the whole story especially digital ones they take "snap shots" to compare. if you want a true reading of what your dishing out attatch a cap. what ever voltage it reaches is the voltage your spiking at. remember a cap can only reach the voltage it is charged with!

EDIT:  by the way have a look at the jule thief curcuit and compare it to bedinies work, i think you will find they are roughly the same curcuit in principle! use a iron core (not torrid) and you have a bedini pulsing generator!

cheers

@ Artic Knight:

OK, speaking of caps, I have a question.  Take my new super caps (2.3 v 10F) for example.  I got the 2.3 volt version so I could charge them with an AA battery (1.5 v) and not blow them up.  But, How do I know how many amps (or mA's) these caps can hold?  For example, if I charge up a supercap with 1.5 vdc from an AA battery, I can get it to light 3 superbright leds for about 20 minutes.  Now, if I used a C or D sized cell, would this make the led run longer as I am maybe putting more mA's in to it?  Do these caps only really store volts only?

I have searched the net and I have to say that I learned more about supercaps from playing with them than I can find info online.  The way they work like batteries has not been mentioned in any of my reading.  All of my prior understanding of caps was that...you put X into them and they will dump X out in a micro second.

I plan on doing, or attempting to do, more experiments involving these and even larger caps so any info you could tell me would be greatly appreciated.  Thanks in advance.  (PS.  I still have some friends of mine that tell me I must be mistaken as a Farad is a huge amount and no one makes a 1 Farad cap much less a 10 F cap.  I told him I could buy, if I could afford, a 5,000 F cap and he said that was impossible.  He is an old radio guy.)

Hey Pirate thanks . HEy i got some of those 2..5 volt 4.7 farads too . Also i got some 5.5 volt .22 farads . I think you said you had an earth battery . I found out that if you put a cap in the input circuit along with the 2.5 volt super cap . it don't light , well it does start to light after about 20 minuets BUT if i use the .22 farad 5.5 volt it lights up almost instant . also it will light brighter with a cap on input But it will light the Jt up a little without a cap .  . Now My earth battery is only putting 1.08 volts at an unmeasurable current  ie 0-1 ma   How does it run a 10,000 mcd led i don't know ? But it does Wonder if you tried it Pirate ?

Artic .. as for the bedini i have to say that is not correct . I have 7 bedinies and they all produce High Voltage and Charge the heck out of lead acid and regular Alki battery's . I have burned up several alkie battery's . I heard a wistle one night and happened to look at my 8 pak of AA and one was Spitting Liquid out the top with a Hiss (Rayovac)  and i have an over unity Bedini that Charges its own battery plus a secondary battery and i have to dump the charge every 3 days cause the voltage gets up to 16+ and burned one of them up already .. I use a cap on the Bedini output . On the Ou Bedini i pules a cap with an scr sometime 60 to 100 volts just to slow down the secondary batt charge. see here.. http://www.youtube.com/watch?v=JRnYQvYEwkM
