current plus radiant charger apears to be OU

[Bradley Malone]

aln nice work...Since this ciruit works with normal current it may be a disadvantage to use parallel charge batteries. Dont know this for sure but i think having all the current run throew one battery would be more of a punch. so maybe try running one charge batt then the other instead of parallelling them. since you already have the data of a parallel charge batt you will be able to see the difference if you do one then the other. I know radiant works better with parallel batts because its more "surface" for the radiant but normal current charging works on the amps going threw the batt and with parallel bats you are basically puting half the power threw each....just a thought.

Hi All,

This thread reminds me of some of the circuits I was also working with back in 2014,which again are very similar to what you have all been working with, found here...

http://www.energyscienceforum.com/showthread.php?t=2054

I asked people to try it back then but no one posted their results... Here is my own quote from that thread... "I have a favour to ask... can someone try this circuit and tell me what they find out."

Dave Wing

Dave, I copied all those on your thread and put them in a folder back then, just never got around to trying them. I'm doing something close to yours and brads, maybe you've tried it, here is a pic and it seems to have no negative effect on the primary circuit. Basically added an ssg between the negatives. Aln

[aln]

A pic nearing the end of the run, I'll go a few more hours and then let them rest and see where they sit.

[aln]

it would also be really simple to change an sg into this type of configuration to see what differences it has.[ATTACH=CONFIG]5194[/ATTACH]

Using the modification Bradley posted, (24v primary, no extra diode, 12 charge battery on other side of coil from primary), I have been running for a day and a half.

Details:

two new 10.5 AH batteries in series at 26.08v to charge
two almost new 10.5 AH batteries in parallel from 11.89v.
This is off one power wind of a 130' 4 filar 26awg trigger/20awg power, small 7 magnet wheel at 750 RPM's 190mA draw.

I started the run at 2030 hrs on 3/23/16
each drop of .2v on the primary(series) resulted in the increase of .1 on the secondary (parallel).
This morning 3/25/16 at 0700 hrs primary was 23.94 and secondary was 12.88, it is still running.

Broken down details

starting:
P=2 batts at 13.04 each
C=2 batts at 11.89 each

35 hrs later:
P=2 batts at 11.97 each
C=2 batts at 12.88 each

Interpretation:
looking like a free spinner with almost exactly out electrically what I put in on the first try.
Could tidy up the circuit, lube the bearings, ad a flywheel, cap dump, generator coils, etc.

Hi Bradley and All,
2 years ago I found a schematic postet by Broadie G.Williams and it describes a typical DCDC bucking (step down) converter explained in a lot of websites containing
standard electronic circuits. You will find there the typical triangle wave you posted here. but congratulations to your finding ! stay on working on this and it will lead you to a sure and relyable method
for measuring the input/output efficiency of any pulsed coil curcuit while observing the triangle on a oscilloscope. You can easily adjust to max power output !! in a few minutes...

There is a lot of great information on this thread and I am enthusiastic to see this research on an SSG variant. Bradley that Arduino logging code is also impressive even if not useful on the first go. To think even something like that was a half million dollar IBM and a computer sci department 50 years ago, not it is a ten dollar chip and a few public libraries. Am also writing cause I uh gobbled up the last of the 4,000,000 UF 4007s for 8 cents on Amazon that Aaron mentioned. So Bradely if you need some for this project or if anyone else is sore about it ... for the low, low price of, joking, joking, but seriously if anyone needs these or was looking forward to them I can just mail you ten or twenty or fifty. Don't know what I will do with 400 of the things. Keep up the good work.

graph

this is the test i just completed. I ran the machine for one hour...the logger was having hiccups so I just did the gopro deal and graphed the data by hand. as you can see on the graph the charge battery started at 1.08 volts and finished at 1.27 so it raised a total of 0.19 volts. I did not graph the supply batteries because i only took five measurments during the run and they were 2.528 at the start (2.517 at 15 minutes) (2.506 at 30 minuntes) (2.497 at 45 minutes) (2.493 at 60 minutes) with a total drop on the primary batteries equaling 0.035. looking good so far...more "in depth" test to come!!

[Bradley Malone]

Peter...other than the extra diode you have could you think of any difference in putting the battery before or after the coil. The reason I put it after was I remember John talking about switching the negative so that the charge is already sitting on the positive, can't remember exactly how it was put but something like since it was already charged on the positive side when negative was connected then it was ready to go. with the battery after the coil the positive would be charged up by the current and the negative would "switch" through the diode. I will be testing both just to see but was just asking in case you had already tried it and decided for some reason that before the coil was better.

On a side note I just got everything set up to run a test on my small AA battery powered machine. I drained one battery down to .970 and am letting it re-stabilize before I get it going. Going to be using the data logger that I posted to hopefully be able to make a graph of the charge battery, and I am going to hook up a time lapse gopro to watch my multimeter hooked up to the run batteries. With the gopro I am going to go back and plot the time and reading manually so I can make a graph of that also and compare. I am also in the process of making an arduino controlled battery discharge circuit so i can measure the actual amount of energy in the battery instead of just voltage measurements...I have come to learn a voltage measurement is not a foolproof thing...thanks to all you fine folks

good luck to all...and keep up the good work!

OU into batteries is great, especially with Large wet PB cells, nice sharp pulses and offtimes - gearing the pulse size too the batter size is the tricky part too ovoid loosing NRG, i found a simple bridge frmo the mains with a series capacitor on one rail of the bridge input, too be excellent, bridge outpuot straight over the batteries, and my country mains is 240 v, excellent desulphate and charge speed / efficency, a real contendor !! but currently working on rosemary ansile circuit - GOT COP10 reliable design and trying too market it, please , a little supoprt would be awesome.

I literally spent thousands of hours on those Ainslie experiments. I do not believe you will see COP 10.0. The most I saw was 2.0 but was more interesting was that when I underdrove the 555, it went into strange oscillations and the resistor dropped up to 5C below ambient.

Thanks for posting your circuit Peter, I've been wanting to experiment with it for a while.

Here's one version I quickly put together. I already had the tape drive motor SG, so it only took a few minutes to get this running.
It's charging the heck out of B3!

I'm thinking about how I might be able use this in a four battery Tesla Switch

Hi All,
Sorry to chime in here...but just a pointer if you read the Advance Battery Charging Circuit Patent ' Circuits and related methods for Charging a Battery''
the significance of the Node 30 says a lot about what is going on in here.. This Patent according to me is a Multitude of Combination of the modes and topology and the other Associated Bedini Patents. Must tinker with this if you are to get a feel of the differences..
Rgds,

also forgot to add that it is coded to take 5 samples and average them for the reading to get rid of any erroneous readings. you can change the sample count and also how often it samples by changing the sample number or "log interval" at the top of the code.

[Bradley Malone]

I have a logger that works ok with AA batteries. it is only off by 0.01 volts so its good enough to make a graph. I am using a voltage divider made from two 100k resistors to the A1 pin on the arduino. I am using a ds3231 Real Time Clock and an sd shield to log everything. here is the code if anyone has this stuff laying around.

#include <SD.h>
#include <Wire.h>
#include <RTClib.h>

#define LOG_INTERVAL 2000 // time between readings
#define SYNC_INTERVAL 10000 // time between sd write
uint32_t syncTime = 0;

#define NUM_SAMPLES 5 // change to times analog is read(averaged)

#define redLEDpin 10 // write to sd status pin
#define greenLEDpin 11 // analog read status pin

#define battPin A1 // analog read pin

RTC_DS1307 RTC; // define clock object
const int chipSelect = 4; //set to chip select pin on shield

unsigned char sample_count = 0; // current sample number
float sum = 0; // sum of samples taken
float battVoltage = 0.0; // variable for analog read data
File logfile; // file to write to

void error(char *str) // error string
{
Serial.print("error: ");
Serial.println(str);
digitalWrite(redLEDpin, HIGH);
while(1);
}


void setup() // setup
{
Serial.begin(9600);
Serial.println();

pinMode(redLEDpin, OUTPUT);
pinMode(greenLEDpin, OUTPUT);
pinMode(4, OUTPUT);

Serial.print("Initializing SD card...");

if (!SD.begin(chipSelect)) {
error("Card failed, or not present");
}

Serial.println("card initialized.");

char filename[] = "LOGGER00.CSV";
for (uint8_t i = 0; i < 100; i++) {
filename[6] = i/10 + '0';
filename[7] = i%10 + '0';
if (! SD.exists(filename)) {
// only open a new file if it doesn't exist
logfile = SD.open(filename, FILE_WRITE);
break; // leave the loop!
}
}

if (! logfile) {
error("couldnt create file");
}

Serial.print("Logging to: ");
Serial.println(filename);

Wire.begin();
if (!RTC.begin()) {
logfile.println("RTC failed");
Serial.println("RTC failed");
}

logfile.println("millis,stamp,datetime,battVoltage ");
Serial.println("millis,stamp,datetime,battVoltage" );
}

void loop() // loop start
{
while (sample_count < NUM_SAMPLES) {
sum += analogRead(A2);
sample_count++;
delay(10);
}
float battVoltage = ((float)sum / (float)NUM_SAMPLES * 0.004912) ;
// change 5.015 to measured actual refference voltage
delay(10);
DateTime now;
delay((LOG_INTERVAL -1) - (millis() % LOG_INTERVAL));
digitalWrite(greenLEDpin, HIGH);

uint32_t m = millis();
logfile.print(m); // milliseconds since start
logfile.print(", ");
Serial.print(m); // milliseconds since start
Serial.print(", ");

now = RTC.now(); // log time now
logfile.print(now.year(), DEC);
logfile.print("/");
logfile.print(now.month(), DEC);
logfile.print("/");
logfile.print(now.day(), DEC);
logfile.print(" ");
logfile.print(now.hour(), DEC);
logfile.print(":");
logfile.print(now.minute(), DEC);
logfile.print(":");
logfile.print(now.second(), DEC);
logfile.print('"');
logfile.print(", ");
logfile.print(battVoltage * 2.0129); // change 11.132 to measured voltage divider (batt voltage divided by voltage out)
logfile.print (" V");

Serial.print(now.year(), DEC);
Serial.print("/");
Serial.print(now.month(), DEC);

logfile.println();
Serial.println();
sample_count = 0;
sum = 0;
digitalWrite(greenLEDpin, LOW);
if ((millis() - syncTime) < SYNC_INTERVAL) return;
syncTime = millis();

// blink LED to show we are syncing data to the card & updating FAT!
digitalWrite(redLEDpin, HIGH);
logfile.flush();
digitalWrite(redLEDpin, LOW);
}



the multiple after reading the battery voltage is found by measuring the Aref and dividing it by 1024. then when it prints you multiply it by the divider ratio witch for me was 2.0129. anyone doing this will want to measure their reference voltage and divider and replace these values in the code. I used the voltage divider in the hope of being able to read 12 volt batteries but when i try it they read off by 2 volts witch is not good enough...but as i stated it reads only 0.01 off when reading AA batteries so for a small scale operation it will work.

Thanks Patrick,

I have been drawing the circuit wrong for a while... Memory is going down hill I guess. Here is the correct drawing.

-Dave Wing

Thanks Dave,

I have tried that before but it separates the current punch on the inverted battery from the spike going to a separate battery.

From my brief testing, Peter's variation with the alternating current/spike/current/spike to the same battery seems to work best.

Bradley's probably should do the same for the most part, but just requires testing to have a real comparison.

Just starting off with a full charged battery in all 3 positions, the battery receiving the charge was pushed to 16.9 volts before I realized it was that high.
With any other variation of normal SG, common ground mode, etc..., none of those will push the battery to that voltage in a short period of time like that.
My SG was a 7 power winding 1 trigger SG - the old plastic bicycle wheel kits that were available for a short time.

Will do more thorough tests with a battery that is drained down - someone is working on a data logger and auto battery rotator.
