Hello gays im new in this so… i don’t know (anything) about it? 
I know programming a little. 8)
I’m trying to build my first hexapod with 6 legs and 12 servos. but i don’t know how to start, what do i need? 
Take a look at existing 12 DoF hexapods:
lynxmotion.com/c-145-ah2.aspx
lynxmotion.com/c-107-mh2.aspx
lynxmotion.com/driver.aspx?Topic=assem10
This will give you some ideas about configuration, servos to use as well as suggested electronics and code.
The SSC-32 servo controller has a built-in 12DoF servo sequencer which makes coding a lot easier.

What about this servos i have this one:
ebay.it/itm/N-2-pz-x-Servo-M … 1270183001
and ill need to buy that servo controller…soo thank you for the links.
Note that although the servo might be small, it can consume high current, so whichever battery you choose should be able to discharge at high current.
