Today we are on step 8 of 10 steps. We wrapped electrical tape around the soldered parts of the wires, so any current when we are using the charger doesn’t go somewhere else. If we have time today we will glue down parts of the USB and battery pack, so it won’t move around when the Altoids tin is being moved. I think we will try to glue everything down with hot glue. We will also put the batteries in the batteries today so they can charge up with the solar panel.
