I prefer to take a stroll out of campus during long breaks and stay indoors listening to music on shorter ones.Just the other day, a friend of mine decided to join me for a walk.As we walked, we spoke about the projects we were involved in.He said to me that he wanted to build a "clap detector".It's an easily doable project, (a half day's project infact starting from buying the components to fabricating on pcb).
"Challenge accepted",came the equally quick response.
A clap detector is a very simple device that makes use of an microphone(condenser type),a relay and a few other resistors,capacitors etc. to detect "claps" and turn on the relay.In this way, a light,radio or fan can be turned on by a clap.
While working on the project, my mother told me that she could actually make use of this device if it could record the "whistles" made by a rice cooker and display it in some manner.
GENIUS!
I ran to the nearby electronics store,bought some 7 segment displays which would be indicative of the number of whistles and also a small buzzer.The buzzer buzzes if the whistle count is 4,5 or 6.
USE 1: Now we know one more use for the clap detector and it is in detecting whistles made by rice cooker,a tea kettle or a milk boiler(those of olden days wherein you will have fill it with water first before pouring in milk) .
"what's it used for,apart from the very obvious fact of detecting claps?" I asked.
This question of mine probably put him off, making him hit back with
"Well,why don't you build one and show me other uses for it.".
Challenges are something that I relish.It helps keep me occupied ,move away from academics and also give me chance to learn.

Here is how its turned out to be.
It may look fussy,but with a single evening I had to build it, I think it's turned out "OK".
USE 2: Another situation in which I use this guy is at class.
When the teacher is not inside the class, there is constant noise made by chatter of the students, me being involved with my music.
A lot of the time what happens is that the teacher enters the class without me noticing at all, for which I am punished by being the target,the rest of the class.
The solution to this is just replacing the buzzer by a vibrator motor.
So now, whenever the teacher enters the class,everyone falls silent ,my device detects this change and turns on the motor giving me an indication.
USE 3:This could also be used to detect if your baby is awake.Once the baby is awake and cries,the wireless module on the system(this one doesn't,will have to add one) will send out an indication to the parents.
PS:BLURRED PHOTOS AHEAD!!
That's it folks.
Let me know if you found out a use for it.
