LEGO lie detector

Nice Make! – “You can’t get more simple than the Galvanic Skin Response GSR sensor. It is just a cut 9V LEGO motor wire and some aluminum foil wrapped around your fingers with tape. I was inspired by talks by Mindfest panelists Karen Wilkinson and Mike Petrich who talked about using this type of sensor.” [via] – Link.
