Hello.  this is my entry for the Green Tech Contest.    


  1.  About 30 in. of PVC pipe
  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
10.  USB cable & connector
11.  Tinkertoys (optional for fan)
12.  Wire cutter
13.  PVC pipe cutter
14.  Small pliers
15.  Hammer
16.  Small piece of wood to fit in hole of tinkertoy

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.
this is a great instructable but you wired the solar panels and batteries inproper. inorder to conect multiple dc power supply you need to do it in a certain way positive to negative. like for example a tv remote, the batteries run into eachother (positive to negative) so for solar panels you simply solder one of one panels negative to the other panels positive after that you are left with a positive and negative wire those would be the output and ground. you connected yours in parrallel which isnt wrong but for a project like this it isnt well sutible. if you connect them in series you will double your output while mantaing the same cap rating. heres a link to a website i just found. http://www.zbattery.com/Connecting-Batteries-in-Series-or-Parallel i didnt mean for my comment to come off as negative feedback because it isnt, i really like this idea! the wind generator is fantastic!

Could you please detail that "circuit board"?
What is it, or where can I get it?
Part number, serial number, link to the store?

I got my solar panel from a garden light and I just used the circuit board that was with it.

Sorry for the late response.
