  7. Raul Romo:

    cool vid, out of focus, but good idea

  8. TheDutchHD:


  9. Gursehaj Singh:

    and how much current is produced ?

  10. Gursehaj Singh:

    what should be the range of power source

    for example 6 — 10 Volts or what?

  11. Deena Lucas:

    Where do u get the voltage regulator

  12. galaxymode:

    9v battery, 9 v battery holder, solder iron, 7805 voltage regulator.

    I recomend getting 6 aa batteries in series to charg that because then it will give the amprige needed to charge big things. Like a raspberry pi. Wich is wat I use this for. Vote up please so that others. Can see this!

    dude i said «zener» diode+ i tried it and it worked….after some research i also came to know that a voltage regulator is made of zener diodes

  19. aadz93:

    no the voltage regulator takes that 9 volt battery and converts around 4 volts of electricity into heat there leaving 5 volts where a diode is quite different

  21. Vikram Venkatesh:

    can i use a 5.7v zener diode instead of voltage regulator?
