There are a zillion usb lamps. This is just the one I made. One feature I made sure to add to mine was the ability to use regular batteries when a computer was not available.

Notice: soldering, mechanicals skills, and a bit of knowledge about electricity are required. Get a professional to help if you are not sure about this project. Do this project at your own risk to yourself and to your computer. I will not be responsible for any issues.

Step 1: What you need.

1 Vienna sausage can emptied.
1 clear plastic cup.
1 Usb extension cable (you will use both ends) If you have the right cable one end will plug into the other end. If they do not, you have the wrong cable.
1 - 3 battery flashlight bulb.
1 Pringles can cover,.
glue.
3 batteries
tape
extra wire,
Foil

Tools:
Drill with various bits
wire cutters.
soldering iron

Step 2: What to do: part 1.

Picture of What to do: part 1.
Take the usb extension cable and cut it in half.
For both ends, strip the casing off so that 4 wires are exposed.
You only need the red and black , so cut off the other two little wires on each cable.

Step 3: What to do: part 2.

Picture of What to do: part 2.
Drill a hole int he Vienna sausage can at the bottom just large enough for the usb cable to fit.
Drill a hole in the Pringles can lid so that you can force the bulb through and be snug enough not to fall out.
Thread the cut wire end of the normal usb end through the hole in the can so it will be easy to solder the wires to the bulb without a hassle.
Glue the foil to the lid with the shiny side up.
let dry.
When dry gently press through the foil so the bulb will come through.
