Garland LED with your hands: a myth or reality?

Original garlands - one of the ways to decorate the room, which create a cozy and festive mood. Few people know that a garland LED, made by own hands, is an easy thing to do. You will be able to create an option yourself, which will suit you and fit perfectly into the interior.

What are the garlands

On the shelves you can find a huge number of different options, so as not to be lost in all the diversity, you need to know how they are arranged and how different. Knowing what a LED garland circuit is, will help you if you decide to do it yourself.

Kinds of garlands:

1. Traditional garland thread.
2. Garlands of a grid.
3. Curtains.
4. One of the variants of the curtain is the garland-icicles.
5. Durolight.
6. Kiplayt.
7. Stroblight will create flicker.

Now that you have decided on the types of garlands you create, you need to carefully study the wires and types of food that can be used to create the garland yourself.

Types of wire and power

Modern garlands are made using one of three types of wire. For this, rubber, silicone and PVC materials can be used. For street scenery, the first two types of wires are used, because they have increased water resistance and are sufficiently resistant to temperature changes. In premises it is possible to use budgetary fur-tree garlands light-emitting diode with a PVC-wire.

By type of power, you can distinguish two types: stand-alone and electrical. The first are ideal for decorating facades and places where it is impossible to bring electricity. These garlands of street LEDs are powered by batteries. Due to low energy consumption, a large amount of time can work. A big plus in mobility, they can easily be taken with you to promotions. Electric plug into the outlet.

Option 1. Create a garland from the old keyboard

It happens that a garland is needed in the shortest time, and there is no money to buy it. Then the master class "Garland LED, made with own hands" will come to the aid. Consider the most budgetary version of the alteration of the old computer office equipment, for example, the keyboard and mouse.

To perform the work you will need:

• A few unnecessary keyboards (you can not work).
• Soldering iron.
• Resistors.
• Insulating tape.
• Tube-cambric for heat shrinkage.
• Flux or rosin.

First you need to remove various unnecessary wires from the keyboard and carefully disconnect the USB cable. In order to garland LED, made by yourself, was fully valid, it is worth looking for at least five keyboards. Ask from friends, friends or go to local forums. In each there are at least three LED lights that serve as indicators for the command buttons. If there is an unnecessary gamer in the stock, then it will not be priced, because there are a lot of LEDs assembled there. The most interesting option is obtained by mixing different light bulbs from different office equipment.

Instructions

Disassemble the keyboard and get out a small board with the controller. It is to it in the future will be soldered bulbs. It is important to take into account that any garland LED (made by hand) consists of 12 elements that are connected to the resistors in parallel. If you consider that a normal USB gives a voltage of 5 volts and a current of 500 mA.

The natural voltage of each element does not exceed 5 volts. If you connect them directly, they will overheat and quickly burn. It is necessary to lower the voltage. This can be done by pairing the elements together. Thus, each of them will lower the other. But this option is not optimal. It is best to use certain voltage frames that will not infringe on the riot of colorful lights.

Take the cable and burn a little braid on one side. In the bare windows solder. So you will create a garland LED with your own hands of the required length. Get the desired shape, length and isolate the exposed places. Inside the cable, it eats veins: minus - black, plus - red. Connect the whole structure and start testing the street LED garlands.

Option 2. Creating a garland from scratch

If you want to make an interesting garland that meets the specified requirements, then carefully study the figure below. The scheme of the LED garland will allow you to understand the process and thoroughly understand the order of all the elements.

In the case when we consider the possibility of emergency regulation of the multivibrator frequencies as a consequence of the shift at the ends of all available transistors, the question of the complexity of the substitution of field and bipolar transistors arises. In this case, it is necessary to consider the periodicity of switching, if the period is reduced, then the LEDs located on the garland will begin to switch very quickly.

So, used VT-1 and VT-2 can be similar to KTZ101 and KTZ15. To determine the supply voltage and its drop across the entire LED chain, you can use the transistor R2.
