It is very easy and fast at the same time to make a lamp from simple batteries. This is a great way to craft a flashlight or just create temporary lighting. The simple act of properly connecting a lamp and batteries creates an electrical circuit that powers the lamp. The electrons flow to the negative terminal of the circuit and return to the positive terminal, thus keeping your lamp on.

Steps

Method 1 of 2: Use a conventional lamp

Make a Light out of Batteries Step 1

Step 1. Gather your materials

To do this, you can use a light bulb or a small light fixture. Likewise, it is best to use special electrical tape, but any type of tape will do. You will need the following:

  • D-type batteries
  • electrical wiring wire (5 to 7 cm long)
  • a lightbulb
  • Scotch tape
  • scissors

Step 2. Strip the wires

Using the scissors, remove about 1.5cm of the plastic insulation from the end of each of your wires. Do this on each of your threads. Be careful not to cut the cables.

Step 3. Connect the wires and batteries

Tape one end of the wires to the negative side of battery D.

Step 4. Connect your bulb

You now have a wire attached to the bulb, take that same wire and connect it to the bottom of the bulb. Take the second wire and connect it to the bulb. Tape the pieces together.

Step 5. Tie the other end

Take the second cable (the stripped end) and tie it to the other side of the stack. You should now connect to the positive terminal of the battery. When you touch the wire to the positive side of the battery, the bulb should light up. The electrons begin to flow from the negative terminal of the battery, pass through the bulb and arrive at the positive terminal. This creates an electrical circuit that causes the bulb to light up.

Method 2 of 2: Use light emitting diodes (LEDs)

Make a Light out of Batteries Step 6

Step 1. Gather your materials

This flashlight is very easy to make and requires very little material. Make sure you have AA batteries, as larger voltages will heat up the wires very quickly and make your flashlight dangerous. You will need:

  • 2, 5 cm and 7 cm electrical wiring wire
  • 2 AA batteries
  • a light emitting diode (LED)
  • duct tape
  • scissors
  • a sheet of paper

Step 2. Tape the batteries together

Line up your 2 AA batteries so that the positive end of one is close to the negative end of the other. Connect the two batteries using the electric tape. Make sure the connection is secure, so that you don't have to squeeze the batteries together with your hand to initiate charging.

Step 3. Strip the wire

Remove the insulation from the ends of your wire using the scissors. This exposes the wire to bare. Be careful not to damage the cable itself. Do this with your two pieces of yarn.

Step 4. Attach the wire to the LED

Tighten the shorter wire around one side of your LED. Do the same on the other side with the larger thread. Tie them together.

Step 5. Test your lamp

Using the shorter wire, place the stripped wire on the negative terminal of the battery. While placing the wire directly on the battery, place the bare end of the longer wire on the positive terminal of the battery.

If the LED does not light up, swap the wires so that the shorter one is on the positive terminal and the longer one is on the negative terminal

Step 6. Unravel the thread

Once you know what load the short wire should be attached to, unravel and tape it to the correct side of the stack. Fraying the wire will help secure the connection, as it will cover more surface area on the battery.

Step 7. Pack the batteries

Cut a sheet of paper according to the length of the stacks. Roll the paper around them (keeping the cables inside), so you have a small flashlight. Your long cable should not be attached yet. Tape the paper over the stacks with the light on one side, and the end of the longer cable and the exposed side of the stack on the other.

Step 8. Use your finger as a switch

Now you can hold the end of the long wire on the exposed side of the stack. This will turn on your lamp. You can either hold it or tape it to keep the light on.
