Introduction: VUmeter Led

Picture of VUmeter Led

I was thinking of making a present, but it was very special. Then I found a lm3915 chip and said "let's get to work."
Some time ago I had made a map, but I had never tried it before. I'll show you how I did my own vu meter led with acrylic.

●LM3915

●2 LED RED

●2 LED GREEN

●1 LED WHITE

●5 LED BLUE

●10K Potenciometer
●Mini Project board

-First cut 10 frames of 8 cm ^ 2 acrylic.
-Then we make holes in the point (4 cm, 5 mm). And we introduce a nut and then the base.
-Then with a sander, we apply to each side to have a better appearance.


Traducción:
-Primero cortamos 10 cuadros de 8cm cuadrados de acrílico.
-Luego hacemos agujeros en el punto (4cm,5mm). Y luego introducimos una tuerca y una base, repetimos el procedimiento.
-Luego con una lijadora podemos perfeccionar los lados para tener un mejor aspecto.

Step 3: Chasis

●Cut 2 bases of 13cm ^ 2.
●Cut 2 of 12 cm x 5cm.
● Cut 2 of 13cmx5cm.
●Make a small hole for the potentiometer and another at the base to introduce the wires and the iron.
●Apply glue.

●Apply Varnish


Traducción:

Cortar 2 bases de 13cm cuadrados

Cortar 2 tiras de 12 cmx5cm

Cortar 2 tiras de 13cmx5cm

Hacer un pequeño agujero para el potenciómetro y otro para introducir los cables y el hierro.

Aplicar pegamento.

Aplicar barniz transparente

Step 4: Compartment

Picture of Compartment

With the carton we make rolls of the size of the led.

Apply Glue.

Introduce the whole acrylic base and underneath we apply a nut with pressure, to hold it.


Traducción:

Con el cartón hacemos rollos del tamaño del led.

Aplicamos pegamento.

Introducimos toda la base de acrilico y por debajo aplicamos una tuerca con presión, para sujetarlo.

Step 5: Circuit

Picture of Circuit

We set the circuit on the project board.

Pass 11 argos cables through the hole in the wood.

The #11 cable is positive.


Traducción:

Montamos el circuito sobre la project board.

Pasamos 11 cables largos por el agujero.

Puedes sujetar los cables con goma caliente para cuando cierres ninguno se mueva.

Step 6: LED

We closed the box.

To avoid forgetting the location, mark each cable with a number so as not to make mistakes. We put the led in the compartments. With the positive towards the right side.


Traducción:

Cerramos la caja.

Para no olvidar la ubicación, marque cada cable con un número para no equivocarme. Ponemos los led en los compartimentos.

Conectamos todos los positivos. (lado derecho)

Step 7: Cover

Picture of Cover

After soldering all the led, we put a cover.


Traducción:

Después de soldar todos los led, colocamos una cubierta.

Step 8: Functioning

I hope you like honey <3

Step 9: GIFT BOX

Picture of GIFT BOX

Look for a box of at least 11x11 inch.

Paint the box.

Let your creativity emerge.

Write something special.


Traducción:

Buscar una caja de almenos 11x11 pulgadas.

Pintar la caja.

Dejar el resto a tu creatividad.

Escribe algo especial.

So I need to wire the + and - to a speaker directly or a jack? I'm confuse.

Stuxnet97 (author)clausc32016-12-19

You can use a jack only.

DeepakB34 (author)2016-12-14

Thats ok but What
I wanted to ask was that where the Entrade de audio is connected to?

Stuxnet97 (author)DeepakB342016-12-14

The audio input is connected to a sound equipment. As if it were a speaker. Another way is to use a 3.5mm jack, and a dual adapter jack 3.5 (one for the lights and another jack for the 3.5 jack speakers). But the signal from a cell phone is very weak.

DeepakB34 (author)2016-12-13

That audio input, tell me what is '+' and '-'? There is generally three terminals in 3.5 mm stereo audio jack which are left right and ground. So what + & - are connected to?

Stuxnet97 (author)DeepakB342016-12-13

Pin 5 is audio input (+). And the potentiometer is (-). However it works without an order. Because it is not a speaker. When you connect a speaker, the impulse is inward. But the meter only waits for an audio signal. I hope I have helped and sorry for my English :)
