HOW TO CUSTOMIZE YOUR DOORBELL

Picture of HOW TO CUSTOMIZE YOUR DOORBELL
  Hi!! friends. Have you ever wondered how old and boring is the sound of a conventional doorbell? It  says TTTrrringggggg.....

Is it not old for our new generation which belives in action.
So, now its time to change the old thing and customize it with something which has got action in it.

Step 1: MOTIVATION

Picture of MOTIVATION
One day i went to my friends house and noticed that his doorbell gave a sound similar to a cuckkoo bird,whereas mine was a simple one.Then i thought that why not make a doorbell that would shake everyone like that of a machine gun. Ratttatttaaa.................


So, I did some research and found how to make it using a NE555 timer IC.

So, Im going to  tell you how to make it in an easy and exciting way.

Step 2: THE NE555 TIMER

Step 3:

It is very important to know about the pins of the IC in order to build the circuit.

1   GND    --           Ground, low level (0 V)

2   TRIG   --    OUT    rises, and interval starts, when this input falls below 1/2 of CTRL voltage.

3   OUT    --   This output is driven to approximately 1.7V below +VCC or GND.

4   RESET   --        A timing interval may be reset by driving this input to GND, but the timing does not begin again until RESET rises above approximately 0.7 volts. Overrides TRIG which overrides THR.

5   CTRL    --        "Control" access to the internal voltage divider (by default, 2/3 VCC).

6   THR     --     The interval ends when the voltage at THR is greater than at CTRL.

7   DIS        Open collector output; may discharge a capacitor between intervals. In phase with output.
8   VCC        Positive supply voltage is usually between 3 and 15 V.

Okay! Pranjal you are an indian huh?
i may tell your instructable was very good but the way you present is correct for instryctables but i may tell you that you nedd to give a smaller description so it makes reading easy cause every one who search's this type of content know a bit abput electronics and i am samad and i am also an indian and i am also younger than you.
Your instructable was far more that good but you need a better way of presenting your content sooraj bhaiya! yYoc can see my simple instructable which gave me a pro membership very easily you can search it on instructables site my instructale is how to make a soldering iron with a 6 volts battery.

you may need to re-edit the whole text content of the instructable to get it featured(maybe).

1)Make it easy to understand.

"Hi!! friends. Have you ever wondered how old and boring is the sound of a traditional doorbell? Itnnsays TTTrrringggggg.....

Is it not old for our new generation which belives in action.
So, now its time to change the old thing and customize it with something which has got action in it."

2)Get this grammatically correct, be explanative.
3)The circuit diagram should be the secondary information.
4)The Primary resource should ur good labeled diagram(sketched one is recommended and should be well labelled); As this instructable is also read by people with little or no knowledge about the circuit programming, the type of explanation should be Universal.
5)Consider editing the images, get it in focus, make it eye-catching(You can make use of photo-editing softwares too!); If you have no knowledge about photo editing or photography search for these instructables, many good collections of ebooks are available as a whole at this instructable site.

As a part of my personal opinion ,

1)Traditional bells may not be 'uninteresting or unpleasant to hear' as far concerned to others.

2)There are billions of teens and kids of this present generation, you can't judge on behalf of them, whether they like action or not (Its your personal interest)

3)Do you know about cheese and olive oil making process?It's made the traditional way, costs far more than machine made products. Again, don't label it as tradition, depends on your interest.

I also took a look at your another project - Something about camping, Right?

On my opinion,

Deodorants are usually labelled (and are) 'Highly inflammable'
But the idea of utilization was great. So well done....Great! :D
