Save Water... in a smart way

This post is dedicated to all those lazy fellas who don't want to make effort in closing the damn switch of Motor when the Tank has filled.
This is the circuit diagram of the Water-Tank Overflow Checker. 
The circuit is simple; only assume that the Button Icon(fig) is the two wire open connection fixed inside the water tank at the desired level to check the overflow, and the DC motor is the water pump, which is connected to the default ON switch of the Relay.
WORKING:
           As long as the tank is not completely filled, open connection of wires is not shorted by water, so it is like that the Button is not pressed, so Transistor Q1 will be in Cut-Off state, and Green LED will continue to glow and motor will keep pumping water. But as soon as the tank got filled the two wires will get shorted by water, so we can say that the Button is pressed, this will make the transistor Q1 ON and hence the relay toggles, cutting the power supply of the motor, which is indicated by the RED led.

Components Required:
  • Two 1k & One 100 ohm Resistor
  • One NPN transistor
  • 6 volt. Relay
  • 3 mm Red & Green LED
  • 12 volt Rectifier Circuit( For DC circuit power supply)

How to make a Quill....



This post is dedicated to all Harry Potter fans out there! I will show you, how easily we can make a Quill & cast spells or at least you can write them down. Ok to make it, all you need is a Feather!.... may be of Phoenix or whatever u got, but please don’t start killing Birds for it(just kidding), of course you can find it somewhere!
Ok enough talk..… let’s just start
 
Step 1: Choose your pen(prefer a ball pen), a scissor and feather. Now just look at the feather and measure the length, for which pen's refill can be adjusted inside it, roughly.

Step 2: Take out the refill and cut it down to the measured length. And also cut the edge of the feather. As you can see in the picture.


Step 3: Clear the feather cavity by using a sharp & thin thing(like needle) so that the refill gets easily fitted. Make sure u have cleaned only about the length of the refill, otherwise it will not get a perfect fitting.

Step 4: Once you are done cleaning, insert the refill into your magical feather. Use a tape to secure the refill, if you want.


So your Quill is ready!!
 Expecto Patronum

Learning Traffic rules!

 It's my first vb.net program, i'm novice with this language,though  i have studied  C/C++ as an subject, vb is my hobby. Since my subject languages don't provide such GUI as VB does, so i preferred to go with VB to make this quiz program. I started learning VB using online tutorials( there are hundred of sites for the same and it's really tiring to find the right one). But this did not help me until i started building on my own. Obviously i got stuck  right through the beginning, but i googled for the same topic and saved! Finally after a week i had completed it.
     This is simple traffic rule quiz program which is very similar to the Learning License Quiz. Actually i have made this to help people with their knowledge on transport and prepare themselves for Learning License Test!
The questions are taken from the official website of Delhi Transport.
Download the program: Click here!

      Hope it will help you !

2.      In Pop-up window, select the file you want to convert into Audio. Click “Ok”.
3.      Now your selected video will appear, and then drag it to the Timeline view.
4.      You will see two rows- Video and Audio. Right click on the Audio row & select “copy’.
5.      Just below, you will find Audio/Music row, select it then press Ctrl + V.
Now we have extracted the audio, so delete its video part.
6.      Go to the video, then right click & “Delete”.
7.      You can also increase or decrease the volume of extracted audio, press Ctrl + U and adjust the volume as required.
8.      Select “ File” à “Save movie file”  then save it to your desired location. Your Video to Audio conversion is complete!
NOTE: Window Movie Maker supports only Videos of .Avi, .Mpeg extensions make sure you have a converted them to appropiate format. And the output audio file will be of *.WMA not MP3.

Funny Side of Inflation!

FIGHTING INFLATION

India is indeed a lucky country
With leaders like Pawar and a party like NCP
Whose mouthpiece has given
A panacea and not just a remedy
For the biggest worry
Corroding the nation
The food inflation
If sugar is costly
Eat less, avoid diabetes
Reduce intake of wheat
Vegetables, fruit and meat
Remain slim and trim
And you'll never need the gym
If the minister forecasts increases in price of milk, sugar and rice,
He should be given Bharat Rattan
For taking care of the nation
By whipping up inflation!

(Poem by Khuswant Singh)
