Rain or Shine Solar Charger

Step 15 Attach the hardware to the software

Now its time to put everything together. The first step is to turn everything inside out, and sew the battery holder and regulator to one of the inside hems. This is done by hand, through the holes that we drilled in the battery box and controller. The seams are four layers of fabric and attach directly to the snaps, so they're strong enough to hold the weight of the battery and regulator. Then run two thin wires for the solar cells through the stitching that connects the zipper to the bag on the end with the attached battery box and controller assembly. This will bring these two wires under the hood which covers the zipper and outside the pouch.

Its also a good idea to sew the charger plug wires to the seam. This will keep some strain off of the joint on the PCB.
