But if you can't help thinking :"lie detector" at least also think about "The Lie Behind the Lie Detector."]]>Mar 24th 2006 10:18AMhttp://www.engadget.com/2006/03/24/lego-lie-detector-makes-interrogations-fun/http://www.engadget.com/2006/03/24/lego-lie-detector-makes-interrogations-fun/
A polygraph works by testing heartrate (via blood pressure), breathing rate, and GSR - the responses to various questions (standard ones: "Is today Friday?") is compared to the responses to relevant questions ("Did you kill Mother Mary?") and so on. It's notoriously inaccurate as a device for measuring "deception" - all spies are trained how to defeat it (to wit, it's never caught a spy - Aldrich Ames, the most notorious CIA mole passed two of them), but it is of some utility in exacting confessions from those ignorant of its limitations.]]>Mar 24th 2006 11:13AMhttp://www.engadget.com/2006/03/24/lego-lie-detector-makes-interrogations-fun/http://www.engadget.com/2006/03/24/lego-lie-detector-makes-interrogations-fun/

Oh and "...keep your subject alive by powering your detector from batteries and not deadly AC."

Um, this is just wrong. Coming down the tiny wire to the RCX is not 120VAC at 15A or anything silly like that. It's 9VDC at some low amperage where you may feel a slight tingle. Even then, why would plugging it in to the transformer instantly pass all the current through to the person?]]>Mar 24th 2006 12:16PMhttp://www.engadget.com/2006/03/24/lego-lie-detector-makes-interrogations-fun/http://www.engadget.com/2006/03/24/lego-lie-detector-makes-interrogations-fun/
