Hi friends!!!

In this instructable i will tell you how to make amazing dancing lights , so that you can build it up at home ( and even start your own disco if you have enough cash!!!!just kidding).
Using only few and simple components you can make this amazing thing.
So, may you achieve success .
All, the best.

********************PLEASE VOTE FOR ME.THE BUTTON IS IN THE TOP RIGHT CORNOR********************

Step 1: MOTIVATION

I had two reasons which developed this idea in my mind-

1. The first time the idea came into my mind was when I went into a party and saw those beautiful lights and disco balls.Then I thought that how nice it would be if I could make my own.

2. Also I was searching the website and found one of my friends posted an instructable of the same kind using an arduino, but this one is very simple as compared to that as it needs only a very simple components(as arduino is not so simple)

Step 2: WORKING PRINCIPLE

Practically it does not really matter whether you know the working principle or not, but as it is my responsibility i will tell it to you anyway.
The joints in the wire are shown by the dots.

PRINCIPLE

It works on the principle of charging and discharging of capacitors C1 and C2. Current from the positive of battery flows through first set of LEDs D1-D3 to the collector of Transistor1 through resistor R1. Resistor R1 limits current through the LEDs to protect them. The current through R1 charges capacitor C2. It then discharges through the base of T2 and resistor R4. This gives base current to T2 and it conducts. As a result second set of LEDs D4-D6 lights as the current flows through T1.Capacitor C2 again charges and the cycle repeats.

***********In the schematic the led's are of particular colour but i used them of different colours,so that it looks good**********

Step 3: COLLECTING THE PARTS

The parts are not at all complex and can be found at any local electronics shop.

PARTS REQUIRED

1. LED'S (of any colours according to you)
2. BC547 transistors X 2                                                            (BUY)
3. 100 ohm resistors X 2 (BROWN BLACK BROWN)                 (BUY)
4. 10 micro F 40Volt capacitor   X 2                                           (BUY)
5.47K ohm resistor X 2 ( YELLOW VIOLET ORANGE)              (BUY)                         SEE - Calculating resistance value

OTHER PARTS

1. Soldering iron
2. Solder wire
3.General purpose PCB
4.Wire
5. 9 VOLT BATTERY

Step 4: ASSEBLING THE PARTS

First of all arrange all the parts on the PCB according to the schematic.Be carefull for the capacitorsas they may explode if connected in reverse polarity.

Then join all the parts .Then just solder them all together.

Now just turn off the lights and you are ready to party.

enjoy!!!!!!

Well I wolud like to tell you one thing that you may create difference in the blinking of the LED's by replacing the capacitor from 10uF to 100uF.

Step 5: THE CAPACITOR

I would like inform you in advance that an electrolytic capacitor has to be correctly positioned according to its polarity or it may explode.!!!!!!!

Step 6: FAQs

I would like to discuss a bit about the circuit.

Q1) The circuit is not functioning?

Ans)There could be many reasons-
a)The connections in the circuit are loose.
b)The power source is not connected properely.
c)The power source is not working.
d)Either or both of your capacitors is not working.

Q2)The LED's are not blinking?OR Only one set of the LED's is lighting up?

Ans) I myself encountered this problem but was able to solve it.Actually in my case one of the transistors was not working.
And this prompted me to post an instructable.
So, it is probable that the transistor in your case is not functioning.

It may also be that either of the set of LED's is not connected properelly.

IF YOU STILL HAVE A PROBLEM I WILL BE VERY HAPPY TO SOLVE THEM
