'Gerhard Flemming's Replication of John Bedini's "Directory:Bedini SG"'

Is using a target board for the rotor, and PVC pipe for the frame.

here is Idea for you. Hook up the recovery circuit with 6 old flashlight batteries that you know are dead and charge them up, good way to recycle your old batteries. -- John

Good job on the motor, I would put more turns on the coil, move from 450 turns to 900 turns on coil, now that it is running. Good window for transistor base 450 ohms to 680 ohms. -- John Bedini (Oct. 13, 2004, from replications page)

There is my dartboard turning.

Wednesday October 13, 2004

start preliminary tests

October 20

stopped test to build a new coil with 900 turns on power winding

October 21, 04

Resume test with new 900 turn power winding

system uses 220 mA,

resume test with 2 brand new Power Source gel cell batteries W7.5A-12v


All measurements will be on the running system.

Sterling's Comment

Oct. 31, 2004


Call me an optimist, but it seems to me that the average slope on your last set of data from 10/29 8:00 pm until now is beginning to be less steep than in the previous two runs, and it is curving toward less steep.

Isn't this what we were expecting to see as the batteries became conditioned?

I'm thinking perhaps you are beeing impatient in expecting to see results right away.

First, you have not supercharged your batteries, which is a major step toward conditioning them.

Second, you are only using one battery on the output and one on the input, rather than four on the output, taking turns on the input.

Step two needs to follow step one, and you have done neither of these steps.

Nevertheless, I would tend to think from your data that there is a change beginning to take place.

Be patient.

Here is what Peter had to say:

Subject: [Bedini_SG] Re: when supercharging is done

Dear Gerhard,

John and I took a look at your battery charging graph on the wiki

page. We believe that your batteries are fully charged. We draw

this conclusion from a number of points, which you can use as points

of reference for the future.

1) The voltage is over 15 volts.

2) The big dips in voltage during the process, which are large

inpedance drops in the battery, have all but stopped.

3) The voltage has dropped slightly below its peak, and is not

regaining its former top value.

These are the best indicators. Also, feel free to put your ear right

up to the battery. If you hear any sounds inside the battery, it

means the electrolyte is boiling. Also, a sure sign that the battery

is at or near its top voltage.

Sterling must have misunderstood what I told him when he said that

the voltage would "drop at a slow, steady rate". It should

essentially plateau slightly below its peak value and hold steady.

I hope this clarifies the issue for you.


Gerhard: Thank you for the coaching Peter

Here is the chart for the 2nd set of batteries

November 20, 2004

Here is the final test for this replication.

This test is using 4 of the previously supercharged 12 volt 7.5 Amp gel cell batteries..

One cell powering the circuit, 3 cells charging from the circuit..

The rotation is about every 12 hours.

Sterling's Question

Nov. 22, 2004


Would you mind briefly summarizing the following,

1) did you wait until you brought your battery that had been on the front side up to voltage by itself before connecting it to the bank of back-side batteries?

2) what was the voltage differential between the batteries when you hooked it up?

3) what guage wires were you using to connect to your terminals?

Also for the sake of others viewing this page, I should mention that John/Peter recommend four batteries on the back side, rotating in turn to the front, and they recommend that the battery that has been on the front be brought up to the same voltage by itself on the charger before being hooked in parallel to the bank of other batteries on the back end.


Essentially used the components specified in the Directory:Bedini SG:Materials page. Used P600M6A10 for Diode D2 because I had it on hand.

On recommendation of John Bedini I put 900 turns on the power winding.

Transistor base current limit is 680 Ohm.

Batteries: had the Werker battery on hand

Power Source batteries are new

1) Werker WKA 12-5.1A gel cell, pretty new from blown out UPS

2) 4 Power Source gel-cel batteries, 12 Volt 7.5 Amp

Question from the floor : Maybe you could tell us how you affixed the target board to your stand so it would rotate. Close-up photo from both sides would be nice. SilverThunder 14:21, 14 Oct 2004 (EDT)

Answer from builder

I turned a Plexiglas plug on my lathe to fit the hole in the board.

Drilled ΒΌ hole

Glued in plug

Glued in shaft,

ball bearings between 1/4 inch shaft and pipe-frame.
