    greeting to everyone,

    i've need some opinion over here
    is it posibble to boost a 0.5V to 5V ?
    through boost circuit
    my homework was to build a portable movement charger
    where i'll move my motor via gears and generate electricity from it
    i able to generate around 0.5V from my toy car motor.
    i need around 4.6v to 5v and current 0.3A to charge my mobile phone

    and one more thing , any good boost circuit to introduce me ?
    so far , i still researching with my text book
    trying to simulate one

    thx =)

    Possible yes, practical, probably not.

    One of the problems is the 10X increase in current. ½V isn't enough for most semiconductors either.
