Thank you @tagor
Thank you @xs-nrg

Better is if it does not need to be programmed.

Jesus

Your biggest mistake.

here: http://www.youtube.com/watch?v=Q8lVI6-XStI

as you can see he uses a small pcb with a voltage regulator.
the lcd is optional.
the pot is for the contrast of the lcd.

you can use 4 or more buttons.
*speed up
*speed down
*direction
*start-stop

and then you can add tons and tons of other fancy functions and sub routines :)

@xs-nrg

That was great!

What I do not see on the cicuit is the power connections of the pic.
I mean the negative and the positive.

Well you can set almost any pin to be a input/output exept for the supply pins  :) these are fixed.

And here is the typical voltage regulator circuit  :)
Not all components are needed when the circuit is battery fed.

Hi Jesus,

I have to agree with XS-NRG using a pic would help in the long run. Although you do have to use a computer once to write your program, once it is debugged and running fine you don't have to touch the computer again. They allow a lot of flexibility in the long run because you don't have to change components around just tweak the program with your new settings and update.

This site has some very basics using a PicAxe controller which are very good stepping stones to more powerful uP's.

http://www.thebackshed.com/windmill/articles/PicAxe.asp

Look under projects on that site for other PicAxe projects.

Thank you @xs-nrg
The question is, the pic16f627a needs to be programmed? Or it just work when you power it?

Thank you @dreamthinkbuild
I checked the picaxe and it seems promising for a newbie like me.

Yes offcource it needs software.

But that is what makes it so nice actually  :)
You can write it yourself.
You can use and reprogram it over and over again.

I was once like you...
Always building circuits with fixed components.
Those days are over and i am so glad i started to look into microcontrollers  :)

Then:
I cannot do it it is way too difficult.
I don't know how.

Do you see what i mean?
I know what your problem is and i know the solution to it.
And i will help you, if you want.

@xs-nrg

What is the software used to program the pic.
Does it need a special pcboard?

You need a programmer and i use the Microchip MPlab software.
I also recommend to use microengeneering PICBASIC PRO toolsuite. :)

You can find how to integrate PICBASIC PRO into MPlab Here:
http://melabs.com/support/mplab.htm

And programmers are around everywhere if you do a search on PIC Programmer on google.
Here one of my favourites:

Thank you @xs-nrg

Lets see what I can do with all the suggested ways to run the brushless motor.
But it is definitely obvious that I have to step up from the way I do electronic circuits.

In the meantime the parts reach my home I found a 4097 fantastic circuit that does not need to be programed.

Today I was frustrated with the high prices of the PicBasic and Melabs experimenter boards.  I am unemployed at this moment.

I asked for a donation, but then I found 2 inexpensive pic controller boards on a search.

A photo of them included.  Which one do you recommend me to buy and why?

 4097 fantastic circuit

Jesus

That is a useless piece of shit and it won't bring you any good.
That thing is only good for blinking LED's not for motors or coils.
4017 suck very hard because there is a dead time in between the cycles and you field will fall off drop to zero before the next set of coils is energized.

You need a slight overlap between channels and prefferable programmable because then you can adjust it to your needs and wishes.
It needs to be crystal driven in high speed mode that will give you the timing you are looking for.

And you do not need a board, you just need the chip, a 20Mhz crystal, two capacitors and some buttons, and pherhaps a voltage regulator.

You can build it for about 4$ exept for the programmer but that is like your soldering iron it is just a tool and if you do things right it will be the most important tool you will ever have.

If you want a cheap programmer look for a PICkit2 clone on google.
All the files are there and you can also order cheap kit's.
