Feedback To Source

[nievesoliveras]

I composed a new circuit to get a self runing power supply.
I am still developing it.
The problem I need to solve first is the value of the feedback resistor and cap.

If anyone tries to build it, just use any wallwart inside transformer and connect the circuit to it from the lower side.

If it is from 120 to 12, connect on the 12v side.

Update:

The circuit has 7 pins at the circuit side.
It is better and easier to take a flyback ferrite and build the transformer on it.

The formula is:

Divide the desired voltage by the source voltage you are going to use.
The result is the step up number.
Wind at least five turns as primary.
Then multiply the step up number to the turns you wound.

That last step will give you the secondary winding number.

Good luck!

After a long time of frustration I could at least make the Pic microcontroller Pickit2 to accept the program "hello world" from the tutorials contained on the cd that comes with the kit.

Lets see how long will it take to learn to program it on assembler, that is the language used by this kit.

Hey Jesus. It must feel good to get things starting to work from scratch like that.
I remember back in collage I was in the automation compartment, and we got to do a lot with PLC's (programmable logic controller). Programming it from a computer was pretty easy and visualized with lines, boxes etc. I understand PIC is more textfile-typing based, right?

PIC seems to be more down to core though and could do things faster than PLC's, at least that is my impression. Oh and not to mention that a PLC costs a LOT of money

Even though I studied computers I have never in my life had programmed a pic microcontroller and just getting that "hello world" Led on has been a great success.

I do expect to get a circuit that responds to the microcontroller signals to drive an alternator.

And now that I look, this is the wrong thread, the circuit is on another topic that started talking about a good high voltage circuit.

Thank you @hartiberlin!
The page looks good now!
