Introduction

The Solar USB 2.0 Kit is a great way to create a simple solar powered USB charger. The project requires a bit of simple soldering, but can easily be completed by someone who has never soldered before.

  1. Strip the ends of all wires.  This includes the battery holder.
    • Strip the ends of all wires. This includes the battery holder.

  2. Solder the diode to the + (Positive) solder point on the Solar Cell.
    • Solder the diode to the + (Positive) solder point on the Solar Cell.

    • Note: The Diode has a black bar on one side. That side goes to the wire, non black bar side to the Solar Cell.

    • Twist one end of your red wire around the other side of the diode. Solder into place.

    • Snip off excess parts of the Diode legs.

    • Thread the wire through the "Top" laser cut wood part.

    • Twist the Red wire from the solar cell together with the Red wire from the battery holder.

    • Solder both wires to the middle pin on the switch.

    • Solder your other piece of Red wire to either of the outside legs.

    • Solder the Red wire coming off the switch to the Positive terminal on the USB Circuit.

    • Solder your Black wire to the Negative side of the solar cell.

    • Thread it through the "Top" wooden piece.

    • Twist the Black wire from the Solar Cell together with the Black Wire from the Battery Holder.

    • Solder the two black wires to the Negative terminal on the USB Circuit.

    • Move the small white switch so that it is closest to the black wire.

    • Snip off the White and Red LEDs. (They're useless in this project.)

    • Using a screw driver, assemble the body.

    • Use double sided tape to hold down the USB circuit and battery holder.

    • Close up the box and secure the solar cell to the top using tape.

    • The batteries included in the kit may be dead. Use a wall charger to quickly charge them up.

    • Or use some regular AAs for a quick test, though NEVER try and solar charge regular AA batteries.

    • Check out the diagrams in this step if you're worried you missed something.

    • The solar cell on this charger is weak and it may take a couple of days to charge up your internal batteries all the way.
