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.

计算器可以改装成金属探测器
一种新发明出现后，许多人就会努力尝试改进这个发明。这一定律正在一种新方法上发挥效用，这种方法可以将计算器改装成为金属探测器。 Angus MacGyver可能是普及使用DVD及CD光盘改装计算器为金属探测器的第一人。在他的提示下，Razorg 使用AM收音机将计算器改装成金属探测器。无论你想用DVD或AM收音机作为媒介将计算器改装成自制金属探测器，原理是一样的。所有电气设备，如计算器从电路板放射无线电频率，可以通过CD及DVD光盘或AM收音机发射信号，探测金属物体。 这种自制的金属探测器对于那些时常找不到钉子或缝衣针的人来说，是相当方便的。
