Color music with their hands on LEDs

Often, to create the optimal atmosphere for a party, one important detail is missing: color music. How to be? It's not everyone can rent such equipment. In this case, you can produce color music yourself. You do not need to be a genius for this. In addition, all that is needed for this, you can find in any store. It is worth noting that the original color music, created by their own hands, can decorate not only a separate room, but a car. This allows you to relax in a long traffic jam and, of course, not to fall asleep. So, how to do color music with your own hands?

Design of LED garlands

This is the most simple color music on LEDs. To produce it does not require special skills and tools. It can be made from ordinary New Year's garlands, which are used to decorate festive spruce. To make it you will need:

1. A special adapter for connecting to a computer.
2. Christmas garland on LEDs.
3. Insulating tape.
4. Shielded cable.

Material preparation

So, how is color music made with their own hands? To begin with it is necessary to prepare everything you need. To connect the garland to the computer, you need a special adapter. Find it will not be difficult. After all, in this case, you can use an adapter for the LPT port. In addition, a shielded cable or "twisted pair" is required.

How to collect?

Of course, for the manufacture of such a construction it is necessary to know at least an approximate scheme. In this case, it is the following. The control circuit transmits a signal from zero to 7 s DATA contacts using eight conductors of the usual "twisted pair". As a ground transmitter in this case, the monitor of a stationary computer is used. Therefore, in order to get such color music, you will need another adapter for the B plug. Otherwise, the design simply can not be connected.

Connection and verification

After all the parts are connected according to the specified scheme, you must run one of the programs on your computer that allow you to work with color music. For this purpose the well-known Winamp is suitable. Through the USB port, the processed data array is transferred to the device. As a result, the signal is output to eight channels of "twisted pair". This is what makes the LEDs light up in a certain sequence. That's how the color music is made with their own hands from an ordinary garland.

LED Lighting

To get a beautiful color music, you need to prepare a neat shell of Plexiglas, as well as the required number of LEDs. The result is a very original design. This will require:

1. Battery or 12-volt adapter.
2. Cable from headphones.
3. Transistor, preferably KT817.
4. LEDs are five millimeters. Their color and quantity should be chosen based on their wishes.
5. Sandpaper.
6. Adhesive thermo gun.
7. Plexiglass.
8. Electric wire.

Making the case

So, prepare the case. To make it, you need 4 plates of rectangular shape with dimensions of 5 by 15 centimeters, as well as plates of square form - 5 by 5 centimeters. Cut them carefully so that the products are even.

In one of the rectangular plates, several holes must be made. One is required for headphones, and the second - for power. Each of the body parts must be zamatirovat and necessarily sanded. The same thing you need to do with LEDs. You can assemble the case with an adhesive thermo gun. When the design is ready, you can begin the assembly.

How many LEDs do you need?

So, how many LEDs do you need to get good color music? You can make it quickly with your own hands. The main thing is to correctly calculate the number of necessary parts. If you divide the operating voltage of the adapter into the operating voltage of one LED, you can get the required number of LEDs. In this case, there are 4.

Color music by own hands: scheme

First, you need to pass the audio cord into the hole. Now it should be connected to the transistor. After this, all the LEDs must be connected in series to the positive of the battery or the adapter. After that, all the parts must be assembled in one housing. The adapter must be connected to the transistor via a minus. This is the main rule. A series of LEDs must be connected to the transistor.

Particular attention should be paid to the audio cable. It can be taken from old headphones. Under the braid there are three cores. This is one common wire and several wires for the right and left channels. To collect the circuit, only two are needed. Usually this is common and one for channels. The third wire remains unused. To the transistor usually connect both veins. But the adapter is to the channel cable involved. That's all, LED color music, created by their own hands, ready.
