Do It Yourself Beating Heart LED

I created this excellent looking defeating center.. Suddenly designed near the valentine day. .The system has 20 LED`S that flash at a components specified amount. As opposed to the traditional strategy of using micro-controllers i though using a easy 555 Minutter would be excellent ..adding to it ..it would shorten the style and create it less cuber-some for those who either have no understanding or do not want to spend collecting the same.

Step 1 Tools May required :

Things that are required:

1 x NE555 Timer
2 x 10k Resistances
1 x 100uF Electrolytic Capacitor (25V)
1 x 10uF Electrolytic Capacitor (25V)
1 x 9V Battery / 3 x CR2032 Li-ion
1 x Through hole board
1 x 9V Battery connector
1 x IC Base (8 pin)
1 x Push Switch ( to avoid ur heart beats in front of everyone:D)
20 x "identical" Red LED ( Identical is the catch in here.. as if they are sourced differently u might end up having uneven brightness..which will be disappointing)

Wires as required..( it goes to like " Salt to taste")\

And lastly "Spare Time"

Other Things that might be available at hobbyists are:

soldering Iron, Solder, Flux, Tweezers, wire cutters, Helping Hands ( Clamp tool)and hot glue gun.

Step 2 Circuit Details :

Now that u have products..lets discover out what actually is this-

NE555 is the most general of all electronic timers . Its provide variety is 5V To 15V ( We are relaxed with 9V..).Its result present from datasheet is about 200mA which is enough to travel those 20 LED`s of my own..
Using an on the outside packaged routine it can be used to choose time a particular pin goes higher or low( Thats known as Timimg).

Step 3 Construction :

After you have pre-prototyped it ..you need to do the following elements..

1. To create the center look a heart( specifically for individuals with bad drawing as mine) please sketch a center on the non imprinted aspect of the PCB using a lasting marking and then continue in resting the LED`s..
2. Since LED`S are circular they are ought to go by the range as they can be placed with the two feet either up and down or aspect.
3. Solder the feet and level the good ones.
4. Then video the feet.( Thats the interesting part)
5. When you are done..solder the IC Platform.

Now that you have soldered it will..Its time for the unpleasant factor..
CONNECT ALL RANDOMLY ORIENTED +ve Hooks together.
and all -ve together.
You might have to create some typical argument somewhere and other variations.
At the end of the training do analyze the +ve and -ve devices with a a continual specialist and say "crap" if the beep appears to be.C

You will end up with something like this.

After all`s well..put hot stick gun to further strengthen the electrical wiring..( That`s optional)

Then solder the elements as in the routine given previously.
BEWARE- Do not be connected the +ve of the power provide supply to the LED.. Becoz thats what we have 555 for!
