Project- Vibration Detector.

Open House- went on well. Had lots of fun and also gained some practical knowledge about Electronics ;) And my project is 'Vibration Detector'. In short, it detects any heavy vibration and it makes alarm sound. It can be implemented in Car doors, Shop shutters, wardrobe/bureau keyholes etc so that when the thief tries to breakthrough the alarm sound is produced and hence the thief will be caught. With a good sensor we can vary the sensitivity so as to detect even voice signals, seismic waves. It was a great experience teaching the lecturers. I mean explaining the project, circuit, applications etc. Have uploaded a snap of it. Have a look :)

Many were attracted because of the wardrobe/bureau keyhole usage and they asked to sell the kit to them. Especially ladies. May be to keep their jewels (alone) safe :P

That's all for this week. Nothing much. Take care and bye!

PS: All the mugs were really cool and I felt like owning each one of them :D. Thanku for posting them.

Have a nice day,

Impressive work !

Paurna said...

pretty useful stuff.keep up the good work

Vidya said...

Neat stuff !

Selvan Subramanian said...

Very nice, Keep it up ! I suggest you to enhance your project in earth quake detecting system.

Saving human life is better than catching a thieves. Am i right?

You must look into commercializing the product! We can probably miniaturize it and patent the design.. Its a once in a lifetime opportunity!

@Dinesh, Paurna, Vidya
Thank you for nice words. :)Feels Happy!

Yeah, Will do. But the sensor for that is quiet expensive. Dad would be happy to provide that money but what to do keeping that at home. If college will fund and if it will do something on it means will do it ;) Thankyou will make a deal with college :D

Yenakku 1st comment mattum thaan pa kannuku theriyuthu ;) I alwaz see the gud things :P
Vadivelu alavukku nalla irukaaaaaaa?:))

Have a nice day,

senthil natarajan said...

thats impressive! keep up the good work

aval said...

Coincidently I also heard about the projects by school kids for detecting tsuname and also to avoid
train accidents.

Applause to your social interests.

aval said...

read it as tsunami!

Ram said...

That itself is a prize isnt it,provided it is only for a few projects. :-)

Kartik Kannan said...

Its good to see urself involved in projects , but honestly dont u think u can go a level higher in making better projects? Forgive me , my knowledge of elex may not be that high , but this vibration detector are all sensor based things aint it ? I have heard that these are easily available in the market.

Please dont feel offended.Am just curious and asking u as thats what I remember one of my ece friends in college telling me . :-)



Ponnarasi Kothandaraman said...

@Senthil, Aval
Thanku :)

Yeah. U r rite :))

It is sensor, agreed. But apart from the sensor there are other components (Buzzer,LED, FLIL FLOP etc) in the circuit.And I dont get "Easily available" ??? The name itself is quiet new to many. May be Am unaware of it.
To reach the top of mountain, we should first know to walk. Am jus learning to walk :) And thanku for making me think as what am up2.

Thanku :) Feels good.

kanniya said...

haha ... good idea ... but dont ya think its a like too big to fit in the places u wanna fit em in ... am not discouragin r somethin but u need to do things a bit more practical ..

senthil natarajan said...

@karthik : as ponna says- probably its just the begining... and it is good start..!!
@ponna : he is probably talking about something like car alarm which is similar to what you have done... but honestly if this was ur masterpiece kudos to you!

Ricky said...

How about a device to detect Tsunami? If you can program one which is cost-effective, you could save thousands of people and become a multi millionaire. :)

neighbour said...

Great Idea... I hope similar idea is implement for anti theft systems in High end cars which worth a lot.. Its not possible to start the car if it detects that car was under theft.

Nice project buddy.. College life that is the place where you can expose all you ideas...

Enjoy the life....
