“Here's a simple lie detector that can be built in a few minutes, but can be incredibly useful when you want to know if someone is really telling you the truth. It is not as sophisticated as the ones the professionals use, but it works. It works by measuring skin resistance, which goes down when you lie.”-----ElectroMaster
"Here are the details of the specific parts you will need
Part Total Qty. Description Substitutions
R1 1 33K 1/4W Resistor
R2 1 5K Pot
R3 1 1.5K 1/4W Resistor
C1 1 1uF 16V Electrolytic Capacitor
Q1 1 2N3565 NPN Transistor
M1 1 0-1 mA Analog Meter
MISC 1 Case, Wire, Electrodes (See Nots)
Notes
1. The electrodes can be alligator clips (although they can be painful), electrode pads (like the type they use in the hospital), or just wires and tape.
2. To use the circuit, attach the electrodes to the back of the subjects hand, about 1 inch apart. Then, adjust the meter for a reading of 0. Ask the questions. You know the subject is lying when the meter changes. " ------Tom McCurdy作者: 猪头四 时间: 2009-11-2 13:02
没有这个三极管 可以使用2N4401 替代。作者: yzz163 时间: 2009-11-3 23:35

是的，主要通过心理测试。如果不激动，或者汗腺系统失调都回误测。作者: 树叉 时间: 2009-11-4 10:01
现在CIA都会给你来一针，让你意示模糊，自控能力减低，然后想说什么不想想说什么自然一目了然。作者: 猪头四 时间: 2009-11-5 21:47

用不着测谎仪，只需要按着被测者的脉搏拷问就可以了。除了有心律失常的人，这个方法不比测谎机差。作者: 李林王 时间: 2009-11-12 19:35

这个电路实际上就是一个电桥！
