[alternator]

i can conect small SLA battery but i think that alternator"s charge curent is to hight

[alternator]

hi is it posable to use car alternator without conect battery to him ? To conect inverter directly to the alternator

[transistor]

thank you i will try :D

Hi i need some low power transistor that his  base curent somthink about 30-40 ma  and the collector  curent  200-300ma.can somone help me?

thanks for help but my english i not so perfect 
i need this multivbrator for  12 to 220  power inverter  for driving  two power mosfets i is that possible?

[mosfets]

how much gate voltage and curent need  for turn on a power mosfet?

hi i am new here and my english is not so good
i am looking for transistor based multivibrator like this http://www.dieelektronikerseite.de/Pics/Formeln/Astabiler%20Multivibrator.GIF
that provide 50hz
what the vaules of the resistors,caps i ned to get 50hz output and what transisors i must use ?
