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 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,.
Drill with various bits
Step 2: What to Do: Part 1.
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.
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.
When dry gently press through the foil so the bulb will come through.
Step 4: What to Do: Part 3.
Step 5: What to Do: Part 4.
Now press the bulb into Pringles top.
Glue the Pringles top to the can.
Glue the cup to the pringles can top.
You are done for this part so leave the lamp alone for a bit.
Step 6: What to Do: Part 5.
Take 3 batteries and put them together as if they were one battery (in serial not parallel) and tape them up.
Cut two pieces of wire to go from the ends of the battery to the other usb cable end..
Now strip off the insulation and tape (DO NOT SOLDER) each wire to separate ends of the batteries. Using battery holders like I did is a lot easier. You could probably use a 3 cell flashlight in a pinch. The dollar store did not have one so I could demo it that way.
Now take the other ends and connect to the wires on the usb cable. Tape over the connections to prevent a short.
If all works, the lamp should light up.
You have built a flash light! be sure to undo the wires to the batteries when you are finished so they do not get used up.
Step 7: Done.
Danger: Do not leave wires in the sink like I did. There is 100 percent chance of electrocution and death. Cables were removed immediately after the picture was taken.
