"Bomb Detector" Is Simple And Effective Device That Is Capable Of Detecting Any Explosive Material. It Is Cost Effective, Portable, Reliable And Accurate.
Bomb Detector Is Useful For Security Checking. It Can Be Used To Detect Slightly Big Size Metallic Objects. It Uses A Sensing Coil. This Coil Is Kept Near Metallic Objects For Detection. Input Of Circuit Is A Weak Colpitt's R.f. Range Oscillator. Sensing Coil Forms Parts Of Tuned Oscillator. When Coil Is Brought Near Metallic Object; Magnetic Energy Is Absorbed And Oscillator Fails To Work. Finally Transistor Conducts And Buzzer Is Activated. It Uses A 9v Battery. After Connecting Battery,the 4.7k Preset Is Adjusted Until Circuit Stops Sounding.

WELL,BY PARTICIPATING INTO COMPETITIONS I PRESENT MY IDEAS TO THE WORLD AND GET FEEDBACK ON THE AREAS I NEED TO WORK WHICH WILL HELP IN THE BETTERMENT OF MY PROJECT.MOREOVER I SEE OTHER IDEAS TURN INTO REALITY.WINNING GRADUALLY DOES NOT MATTER IF I AM ABLE TO MAKE A PROJECT ON MY OWN.I AM A BIG FAN OF THEORETICAL PHYSICISTS "ALBERT EINSTEIN" AND "MICHIO KAKU".ALTHOUGH I CANNOT MEET ALBERT EINSTEIN AS TIME MACHINE DOES NOT EXISTS! BUT MEETING MICHIO KAKU WOULD BE A GREAT FEELING.
