Area 42: Lamp with Pet Bottle, LED and Broken Glass

Christmas is already near and, at this time, nothing better than to decorate all the places with many lights.

To take advantage of the celebration, today we are going to teach you how to build a lamp using a pet bottle, broken glass and some LEDs. Best of all is that the part can be plugged into any USB port on the computer or directly into the power outlet with a cell phone charger.

Materials

Preparing the necessary material:

10 LEDs of any color (we use the ones of blue color);

1 100 ohm resistor;

1 printed circuit board for projects (or parts thereof);

1 transparent plastic bottle;

1 USB cable any;

Glass broken or broken;

Welding equipment;

Hot glue.

When breaking windows, great care must be taken not to cause accidents. To prevent shrapnel from flying all over the place, it is best to put it all in some box or wrap the material with a cloth before it starts to break. Do not forget to use thick gloves to not cut your fingers.

According to Zephyrledlights, the printed circuit board, also known as standard board, can be used in various electronic designs.Before we start work, we cut two equal parts. We will do this because we need them to solder the LEDs.

After that, let’s start the assembly process.

Assembly-Preparing The Leds And Circuit

Let’s start by separating the two printed circuit boards and positioning them both with the side that has the copper tracks out. Then we take the LEDs and distribute five on each side, keeping the same proportion of space between each one.

At this point, it is important to remember to leave them all positioned in the same way: the positive sides to one side and the negative sides to the other. See in the circuit diagram how the components should be connected.

After positioning all the LEDs on the board, we will bend the metal rods of them to the sides so that they do not fall in the hour of soldering the set.

Then we weld all the LEDs on the printed circuit board. Finally, we cut the metal rods.

Then we place the resistor at the end of one side of the board and weld it the same way we did with the LEDs.

The last step is to unite all LEDs into two unique tracks: one positive and one negative. We will do this by using a few pieces of copper wire.

Finally, let’s take the USB cable and cut one end of it, keeping only the one that has the main connector. The other side has four wires inside it: one white, one green, one red, and one black. What we need to do is keep only the black wire that is the negative and the red wire, which is the positive wire. The rest, we can cut without problems.

Before welding the cable from the board, we will open a hole in the bottom of the plastic bottle to pass the wire. After that, we must weld the red wire to one of the resistor terminals. The other terminal of the resistor must be connected to the positive signal line of the LEDs.

To conclude, we welded the black wire into the negative line of the circuit. That part is ready.

Preparing The Glass To Fill The Bottle

The glass part is a bit dangerous and should be done with care as it can cause accidents. Before handling broken glass, put on gloves and make sure to wear goggles and face shield.

Let’s put everything inside a box – to prevent shrapnel from flying around the room. We will use a hammer, but you can do as you please, as long as you are careful.

Finishing The Assembly

After breaking the glass, we will deposit a little at the bottom of the bottle, so we have a place to fix the circuit board.

What we are going to do now is to finish positioning the circuit of lights inside the bottle and, little by little, put the chopped glass inside. This time, we must be careful that the glass does not damage the circuit board, as sharp parts can damage the assembly.

After that, just close the bottle with the lid and you’re done! Just plug in the USB port, turn off the lights and enjoy the special effects!

Important tip: Because the power connection is USB, you can connect this device to any device that has a USB port, including mobile phone chargers, computers and notebooks.

An interesting observation is the possibility of modifications. Instead of working with a pet bottle, you can use a glass bottle to mount this lamp. The LEDs can also be of any color you want, just remember to calculate the correct value of the resistor before doing this, since each one has a different voltage.
