Fusionchip's Bedini Feedback to Source!!!

Hi,

Here is my Helmholtz Coils Oscillator battery charger.

Adjusted, the circuit uses 0,1 amp.at 12,00 volt from the lab supply.

I have two 12 volt 7 Amp. GEL batteries in parallel on the output.
Both batteries is charging well. Started out as 10,5 volt but has gained voltage up to 11,24 volt
in half an hour charging. The coils and transistor runs very cool. No heating in the circuit.

Now it is exciting to see how long it takes to fully charge both batteries.

Hey Groundloop would you be able to describe how can I build that coil myself?

And do you mean that the battery that runs is the same that charges, correct?

@AbbaRue,

Thank you for explaining how to build lead acid batteries.

One question, where do you get the lead dioxide (PbO2) to put on
the lead plates?

I do not agree that 7 amp batteries is to big to see if a circuit is o/u or not.
If a circuit puts out more than it receives then a depleted battery will gain
voltage. If not there is no o/u. I always try to design my test circuits to use
one battery just for that reason.

Fausto,

No, on this circuit I charge two paralleled batteries from the circuit output.
The input power is from my lab supply. I like to test the circuit before I
start modifying the circuit for closed loop operation. I will try to loop the
output from the circuit later on.

Making the coils is easy, find a round item (a jar or bottle) and wind the copper
wire around that item. Slide off the coil and tape it all the way round. I used
a glass jar with a diameter of 84mm. I used 0,35mm enameled copper wire
and 200 turns.

When you connect the homemade battery to a power supply it will develop the PbO2.
I once bought a new motorcycle battery from Canadian Tire and it was on the shelf without acid in it.
The case was transparent and you could see the plates inside.  All of them were just lead, no PbO2 plates.
They told me I had to come back the next day to pick up the battery because they had to add the acid and
get the battery conditioned to the right polarity by charging it over night.   
What ever polarity you give the homemade battery with the first charge that will remain it's polarity.
If you take an almost completely dead lead acid battery and connect it up in reverse to a power supply
you can change the polarity of the battery.

What I meant about it being difficult to see if large battery is charging is that it takes a long time to see results.
A very small amp hour battery will charge and discharge within minutes instead of hours. 
If this bedini fan motor can run off a very low amp hour battery for hours without a change in voltage like some reported,
that in itself would be significant.

Hi,

I guess that nobody is even remotely interested, but here is my newest build.

The rotor is inside the coils and runs very well indeed. The coils is approx. 50 Ohm (DC)
and is wound around a plastic tube. Each coil is 500 turns 0,35mm enameled copper wire.

EDIT-1 I have measured the input usage. I'm not able to see how much current this motor use.
           My best estimate is that the current usage is less than 5mA at 9,27 Volt.
