Take four solar path lights and remove the base stems. These you can use as garden stakes or for another project.
Twist off the tube shapes lense piece from the solar cell top. Now you have the solar cell and LED light. If you turn it upside down so that you are looking at the LED you can see three screws holding the thing together. Remove the three screws to reveal the internal circuit.
Now you can see a battery socket and a small circuit board.
Cut off all the wires close to the circuit board. You want the wires to be long so you can use the parts later.
Take two of the battery holders and the 4 solar cells for the project.
Mount the four solar cells onto a board as seen in the photo. Then mount two of the battery holders.

Connect all of the solar cells together in parallel. Then run all the negative leads to each of the two negative leads on the battery sockets. Connect both sockets in parallel.
Connect the positive leads of the solar cells to a diode, then from the diode to the positive sides of the battery sockets.
Put two batteries in, place it in the sun and it will charge the batteries.
