2. 3 T-pieces of PVC pipe
3. 5 90 degree pieces (right angle)
4. Altoids tin
5. 2 rechargeable batteries & battery holder
6. Solder iron & metal
7. Solar panels and its circuit board
8. Small motor
9. Lots of wires

Step 1: Cut the Pipes.

   Cut the pipes into these measurements using the the PVC pipe cutter.

4- 3 1/2 in. pieces
2- 2 1/2 in. pieces
1- 9 in. piece

The width of the pipes that I used is 3/4 in. wide.

Then put the pipes together so it looks like this.

Step 2: Make a Hole.

Then drill a hole in the T-piece that is connected to the 9 inch piece so the wire can come out.

Step 3: Connect wires together.

Next, you get wires, the battery holder, and the part where you plug in the USB cable.
Then, conect the two battery holders together and put extra wires on each side.
On one side of the battery holders connect the USB connector there; on the other side, just leave the wires there. 

Step 4: Connect the Circuit Board.

Now attach the circuit board to the two loose wires and solder them together.
Then solder all the wires together and make sure the wires go from positive-to-positive and negative-to-negative.
Then after the solder metal has cooled down put it inside the Altoids tin.

Step 5: Connect the Solar Panels.

Now solder together the solar panel and the wire on all panels.
Then connect all the positive wires together and all the negative ones togather.
Then gat two wires and use oe for the positive wires and one for the negative.
Then solder them.

Sorry for the late response I8nite. I actually had a few set backs and the batteries wouldn't fit, so I had to use my two back up AA batteries. It would work better if you had 3 AAA batteries. - Ceci Bot
