Sorry for the bad pictures, the only camera I had available was my phone camera, and I couldn't get it to focus sometimes.
Step 1: Parts List
> Soda bottle - I used a glass one.
> Flashlight bulb and holder - Make sure its rated about 5 volts or more.
> USB cable and connector (if necessary)
> PC (to power it with)
> Glue gun & glue
> Solder Iron and solder
Step 2: Wire Up the Bulb
Afterword, plug it up to test it. If your computer says there is an overload on the USB port or suddenly shuts off, you have a power short somewhere.
Step 3: Glue Stuff
You may also want to glue the USB connecter down, if you're using one.
Step 4: Done!
