Calculator can be turned to a metal detector

homemade metal detector

When someone makes an invention, soon there will be others who would work on improvising it. This is exactly what is happening with a new method of converting a calculator to a metal detector. Angus MacGyver was perhaps the first person to popularize the concept of turning a calculator to a metal detector using DVD and CD discs. Taking cue from him Razorg has displayed the technique of converting a calculator to a metal detector using an AM radio. Whether you want to use a DVD player or an AM radio as the medium to turn the calculator to a homemade metal detector, the theory remains the same. All electronics like calculators emit radio frequencies from their circuit boards that can be manipulated by CD and DVD discs or by AM radios to emit signals to detect metallic objects. This homemade metal detector might come handy for all those of you who often lose pins and needles in their house. The video after the jump shows how.
