Here's how to throw together a DIY polygraph machine with nothing but an Arduino, some wire, and some tin foil.

In this particular case, it’s a DIY USB polygraph-like machine by [Juangg] using an Arduino and sensors on the hardware side, and a Python front end for data visualization.

This one caught my eye - an Arduino-based lie detector that can measure the skin's response to a question. At the heart of this project is an Arduino Nano, based on the Atmel ATmega328 (for the Nano 3 ...
