Step 61: Handle/Electronics: Battery Case

Disassemble your flashlight. Take out the battery case. Sand the ends of it to prepare it to accept solder. Remove the batteries and solder a red wire to the positive side and a brown wire to the negative side (if you can find them, color is not really important).

Pour hot glue over these connections to insulate them and protect them from breaking off. You now have a power source for your hub.

Plug your camera into the USB hub and connect the battery case red and brown (+V and Ground) to the USB hub +V and Ground (red and brown) using alligator clips. The camera shutter should fire, and if the hub has an LED, it should light up. This will only work if you installed the custom firmware I discussed earlier.
