Laser Security System

Bismillahir Rahmanir Rahim

Assalamualaikum, how are you friends. This titurial  i wanna make a simple "Laser Security System" . Its a very simple project, At first we have to know what are the components to make  this project:

Electronics components are:-

1. Buzzer
2. Light dependent resistor (LDR)
3. 1k ohm resistor
4. PNP 2N3904 transistor
5. 3 volt coin cell battery
6. Battery holder
7. Breadboard
8. Jumper wires
9. Laser light

Most of the people are don't know who are beginner about PNP 2N3904 transistor . That's why the project con't run successfully. Now introducing with PNP 2N3904 transistor .At first move your PNP 2N3904 transistor so that the Plane or flat side in-front of you. Now the middle one is Base, left one is Emitter and the right side one is collector.

 Now see the circuit

 diagram:

Now just all the components are put in your breadboard like as a circuit diagram.

In a short 

1. Emitter of PNP 2N3904 transistor and head of 1Kohm resistance are connect together. (mind it its the +3V or Voltage input point)
2. Baseof PNP 2N3904 transistor, tail of 1Kohm resistance and the GND of LDR are connect together.
3. Collector of PNP 2N3904 transistor and Positive side of  Buzzer /LED  connect together
4. Connect LDR and Buzzer/LED negative sides together. this one is GND of this circute.
5. Last job is the circuit connect with a power source ,Here we use +3V .

now put your laser ray on your LDR then buzzer sound will be off and when something comes over the Ray then buzzer make a sound.

Best of luck

Virus! My files turned into shortcuts (Solved)

Bismillahir Rahmanir Rahim

If your computer is the one that infected yours and your friend’s memory sticks, you need to update your antivirus. If even after the update the antivirus fails to catch the infection, you definitely need to use another product.

Step ONE

Windows has the bad habit of hiding certain files and much worse: their extensions. You may for example run a dangerous program like “photo.jpg.exe” just because Windows only shows “photo.jpg”.
To fight the memory stick infection (and as a safety measure for the future) is good to make all files visible.
(The following steps apply for both Windows XP and Windows 7)

1. Click on Start
2. Click on Control Panel
3. Pick Folder Options
4. Click on “View” tab
5. Clear the following check boxes:

Hide protected operating system files (Recommended)

Hide extensions for known file types
Accept.

Step TWO

Now that your vision is restored, delete Autorun.inf, and everything you don’t recognize as yours. Delete the shortcuts too, because they are part of the infection and not related with your files, even if they have the same name.

Step THREE

On Windows Vista and 7:

• Click on Start
• Type cmd in the first box you see
• Press ENTER

On Windows XP:

• Click on Start
• Click on Run
• Type cmd
• Press ENTER

On the black Window that appears write the commands shown on the picture. Replace X with the letter of your infected USB flash stick or hard drive, for example attrib -h -r -s /s /d F:\*.*
Wait a few seconds

Finished!

O Sajna Aaja Ve Lyrics Translation (Table No.21) & MP3

Movie: Table No 21
Music n Lyrics: Gajendra Verma

**********DoWnLoAd**********

Love in you is losin my soul
I was in the lost battle
death at my door
A dog in the backyard
Feels for my pain
Beau in broken bottle
Beatin rain

O sajna aaja ve
Dil di sunava gallan
Muh te uda ke pallan
Sir choom laan
O meri gal sun ja ve
Dil mera hoya jhalla
Ek bus tu hi ikalla
Tere te manave..

O my beloved, come..
I'll tell you the talks of my heart,
removing the veil from my face,
I'll kiss your forehead..
Listen to my heart's talk..
My heart has become mad..
Just you alone are there (for it),
It wishes for you only..

Yoon hi aansu aansu bikhar ke
Humein chain milega mar ke
Pachhtate hain hum tujh se dhokha karke
Zaaya hum pe yoon teri wafa na kar
Jaane jaan hum ko tu daga de

Spilling tear by tear as I am,
I'll get peace by dying..
I regret after ditching you..
Don't waste your faithfulness on me,
Now, O beloved, cheat me..

Tera mera rishta tha bhool
Tu ne ik pal mein mita daala jaise ho dhool
Ab bas main hoon yaadein or gham hai
Ab is gham ko saari umar sahenge hum..

Our relationship was a mistake,
You finished it in a moment like dirt..
Now there is just me, memories, and sadness
Now I'll bear the sadness all my life..

Mann dard se tere bhara hai
Tere naam ka zakhm hara hai
Sab khatm hua par baaki kuch zara hai
Dheere dheere kat rahi hoon jaane jaan
Aansoo thode tu bhi baha de..

The heart is filled with your pain,
The wound of your name is still fresh,
Everything has ended but something still remains..
I'm slowly getting cut, O my beloved..
You too drop a few tears..

Toota dil to sub kuchh jal gaya
Mausam vo achanak khushiyon bhara badal gaya
Khwaab the jitne aankho se beh gaye
Bas karne ko yaad purane kisse reh gaye

When the heart broke everything burnt down,
Suddenly that weather full of joys changed..
All the dreams streamed down the eyes..
Only the old stories were left to recall..

O sajna aaja ve
O meri gal sun ja ve..
