Partnered Output Coils - Free Energy

[TinselKoala]

Talking about scope,  I have Some Siglent SDS1202DL.  TK or anybody else, maybe you can create the topic related to the scope. I can use it just in very limited level of knowledge. I guess there is much more I  can get of it  with your help

That's a nice bit of kit! Very capable for the money.  I like the control layout, it looks like it would be very easy to use. The waveform math is a bit limited, it doesn't seem to do integration, but that's a feature that's rarely used and you can always do it in a spreadsheet from dumped data if you really need to.

MarkE has started an oscilloscope thread; when you have some specific question or measurement problem I'm sure that you can get lots of help there. Congratulations on your nice scope!

Tinsel Koala: Your last coil pic is starting to look like Stepanov and also Kapanadze's three phase transformer in the aquarium2 video.

Hi TK, I c you play with Arduino too. I have burn my previous one a half year ago when I use it as a switch -charging cap from BMF and switching to load.
I got my second board last month and I would like to continue on that project, but I need switching frequency faster of 1ms. Is any change to get it just from the arduino board? I know there are some option I can connect Arduino to my signal generator.

Cheers.

Hi John
You can use a digital output pin of the Arduino to control the Gate of a logic-level mosfet, and let the mosfet handle the heavy switching duty.

Put a diode between the OutPin and the mosfet Gate and a pulldown resistor from Gate to Source.
You'll need to fine-tune the dwell and gap numbers to get your exact pulse width and frequency because the loop() statements take a little time themselves for processing.
You can control these values "live" in loop()  with a couple of potentiometers and analogRead and map statements.
Designate a couple of pins as inputs in setup(), connect the wiper of each pot to the input pins and the legs of the pots to +5 and GND.

Something like:

Code Select Expand



#define DwellPotPin A0  // potentiometer controls pulse ON time
#define GapPotPin A1   //  potentiometer controls time between pulses
#define OutPin 6           //  to mosfet Gate
#define LEDPin 13        //  monitor LED

long int dwell = 0, gap = 0;

void setup() {
pinMode(GapPotPin,INPUT);
pinMode(DwellPotPin,INPUT);
pinMode(OutPin,OUTPUT);
pinMode(LEDPin,OUTPUT);
}

void loop() {
dwell = map(analogRead(DwellPotPin),0,1023,1,99);  // adjust 3rd and 4th numbers for your desired timing mapping
gap = map(analogRead(GapPotPin),0,1023,100,1000);  //adjust 3rd and 4th numbers for your desired timing mapping
digitalWrite(OutPin,HIGH);
digitalWrite(LEDPin,HIGH);
delayMicroseconds(dwell);
digitalWrite(OutPin,LOW);
digitalWrite(LEDPin,LOW);
delayMicroseconds(gap);
}

//dwell: number of microseconds to keep mosfet ON
//gap: number of microseconds between pulses, adjust for delay caused by loop processing

Thanks TK. That's handy to know.
